- An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
- that get passed through the PCI<->ISA bridge chip. So we've gotta use
- both windows to max out the physical memory we can DMA to. Sigh...
-
- If we try a window at 0 for 1GB as a work-around, we run into conflicts
- with ISA/PCI bus memory which can't be relocated, like VGA aperture and
- BIOS ROMs. So we must put the windows high enough to avoid these areas.
-
- We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
- and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
- Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
- be used for that range (via virt_to_bus()).
-
- Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
- to keep virt_to_bus() from returning an address in the first window, for
- a data area that goes beyond the 64Mb first DMA window. Sigh...
- The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
- we can't just use that here, because of header file looping... :-(
-
- Window 1 will be used for all DMA from the ISA bus; yes, that does
- limit what memory an ISA floppy or sound card or Ethernet can touch, but
- it's also a known limitation on other platforms as well. We use the
- same technique that is used on INTEL platforms with similar limitation:
- set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
- We trust that any ISA bus device drivers will *always* ask for DMAable
- memory explicitly via kmalloc()/get_free_pages() flags arguments.
-
- Note that most PCI bus devices' drivers do *not* explicitly ask for
- DMAable memory; they count on being able to DMA to any memory they
- get from kmalloc()/get_free_pages(). They will also use window 1 for
- any physical memory accesses below 64Mb; the rest will be handled by
- window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
-
- We hope that the area before the first window is large enough so that
- there will be no overlap at the top end (64Mb). We *must* locate the
- PCI cards' memory just below window 1, so that there's still the
- possibility of being able to access it via SPARSE space. This is
- important for cards such as the Matrox Millennium, whose Xserver
- wants to access memory-mapped registers in byte and short lengths.
-
- Note that the XL is treated differently from the AVANTI, even though
- for most other things they are identical. It didn't seem reasonable to
- make the AVANTI support pay for the limitations of the XL. It is true,
- however, that an XL kernel will run on an AVANTI without problems.
-
- %%% All of this should be obviated by the ability to route
- everything through the iommu.

- * Low Cost Alpha (LCA) definitions (these apply to 21066 and 21068,

-
-/*
- * NOTE: The LCA uses a Host Address Extension (HAE) register to access
- * PCI addresses that are beyond the first 27 bits of address
- * space. Updating the HAE requires an external cycle (and
- * a memory barrier), which tends to be slow. Instead of updating
- * it on each sparse memory access, we keep the current HAE value
- * cached in variable cache_hae. Only if the cached HAE differs
- * from the desired HAE value do we actually updated HAE register.
- * The HAE register is preserved by the interrupt handler entry/exit
- * code, so this scheme works even in the presence of interrupts.
- *
- * Dense memory space doesn't require the HAE, but is restricted to
- * aligned 32 and 64 bit accesses. Special Cycle and Interrupt
- * Acknowledge cycles may also require the use of the HAE. The LCA
- * limits I/O address space to the bottom 24 bits of address space,
- * but this easily covers the 16 bit ISA I/O address space.
- */
-
-/*
- * NOTE 2! The memory operations do not set any memory barriers, as
- * it's not needed for cases like a frame buffer that is essentially
- * memory-like. You need to do them by hand if the operations depend
- * on ordering.
- *
- * Similarly, the port I/O operations do a "mb" only after a write
- * operation: if an mb is needed before (as in the case of doing
- * memory mapped I/O first, and then a port I/O operation to the same
- * device), it needs to be done by hand.
- *
- * After the above has bitten me 100 times, I'll give up and just do
- * the mb all the time, but right now I'm hoping this will work out.
- * Avoiding mb's may potentially be a noticeable speed improvement,
- * but I can't honestly say I've tested it.
- *
- * Handling interrupts that need to do mb's to synchronize to
- * non-interrupts is another fun race area. Don't do it (because if
- * you do, I'll have to do *everything* with interrupts disabled,
- * ugh).

+ * Remarks about the rationale behind the chosen mapping:

+ * - BPF_REG_{1,2,3,4} are the argument registers and must be mapped to
+ * argument registers in ARCv2 ABI: r0-r7. The r7 registers is the last
+ * argument register in the ABI. Therefore BPF_REG_5, as the fifth
+ * argument, must be pushed onto the stack. This is a must for calling
+ * in-kernel functions.
+ *
+ * - In ARCv2 ABI, the return value is in r0 for 32-bit results and (r1,r0)
+ * for 64-bit results. However, because they're already used for BPF_REG_1,
+ * the next available scratch registers, r8 and r9, are the best candidates
+ * for BPF_REG_0. After a "call" to a(n) (in-kernel) function, the result
+ * is "mov"ed to these registers. At a BPF_EXIT, their value is "mov"ed to
+ * (r1,r0).
+ * It is worth mentioning that scratch registers are the best choice for
+ * BPF_REG_0, because it is very popular in BPF instruction encoding.
+ *
+ * - JIT_REG_TMP is an artifact needed to translate some BPF instructions.
+ * Its life span is one single BPF instruction. Since during the
+ * analyze_reg_usage(), it is not known if temporary registers are used,
+ * it is mapped to ARC's scratch registers: r10 and r11. Therefore, they
+ * don't matter in analysing phase and don't need saving. This temporary
+ * register is added as yet another index in the bpf2arc array, so it will
+ * unfold like the rest of registers during the code generation process.
+ *
+ * - Mapping of callee-saved BPF registers, BPF_REG_{6,7,8,9}, starts from
+ * (r15,r14) register pair. The (r13,r12) is not a good choice, because
+ * in ARCv2 ABI, r12 is not a callee-saved register and this can cause
+ * problem when calling an in-kernel function. Theoretically, the mapping
+ * could start from (r14,r13), but it is not a conventional ARCv2 register
+ * pair. To have a future proof design, I opted for this arrangement.
+ * If/when we decide to add ARCv2 instructions that do use register pairs,
+ * the mapping, hopefully, doesn't need to be revisited.

- help
- The Snoop Control Unit on ARM11MPCore does not detect the
- cache maintenance operations and the dma_{map,unmap}_area()
- functions may leave stale cache entries on other CPUs. By
- enabling this option, Read or Write For Ownership in the ARMv6
- DMA cache maintenance functions is performed. These LDR/STR
- instructions change the cache line state to shared or modified
- so that the cache operation has the desired effect.
-
- Note that the workaround is only valid on processors that do
- not perform speculative loads into the D-cache. For such
- processors, if cache maintenance operations are not broadcast
- in hardware, other workarounds are needed (e.g. cache
- maintenance broadcasting in software via FIQ).

+ * Generic and Software Tag-Based KASAN modes require 1/8th and 1/16th of the
+ * kernel virtual address space for storing the shadow memory respectively.
+ *
+ * The mapping between a virtual memory address and its corresponding shadow
+ * memory address is defined based on the formula:
+ *
+ * shadow_addr = (addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET
+ *
+ * where KASAN_SHADOW_SCALE_SHIFT is the order of the number of bits that map
+ * to a single shadow byte and KASAN_SHADOW_OFFSET is a constant that offsets
+ * the mapping. Note that KASAN_SHADOW_OFFSET does not point to the start of
+ * the shadow memory region.
+ *
+ * Based on this mapping, we define two constants:
+ *
+ * KASAN_SHADOW_START: the start of the shadow memory region;
+ * KASAN_SHADOW_END: the end of the shadow memory region.
+ *
+ * KASAN_SHADOW_END is defined first as the shadow address that corresponds to
+ * the upper bound of possible virtual kernel memory addresses UL(1) << 64
+ * according to the mapping formula.
+ *
+ * KASAN_SHADOW_START is defined second based on KASAN_SHADOW_END. The shadow
+ * memory start must map to the lowest possible kernel virtual memory address
+ * and thus it depends on the actual bitness of the address space.
+ *
+ * As KASAN inserts redzones between stack variables, this increases the stack
+ * memory usage significantly. Thus, we double the (minimum) stack size.

- * OpRegion handler to allow AML to call native firmware
- *
- * (c) Copyright 2007 Hewlett-Packard Development Company, L.P.
- * Bjorn Helgaas <bjorn.helgaas@hp.com>
- *
- * This driver implements HP Open Source Review Board proposal 1842,
- * which was approved on 9/20/2006.
- *
- * For technical documentation, see the HP SPPA Firmware EAS, Appendix F.
- *
- * ACPI does not define a mechanism for AML methods to call native firmware
- * interfaces such as PAL or SAL. This OpRegion handler adds such a mechanism.
- * After the handler is installed, an AML method can call native firmware by
- * storing the arguments and firmware entry point to specific offsets in the
- * OpRegion. When AML reads the "return value" offset from the OpRegion, this
- * handler loads up the arguments, makes the firmware call, and returns the
- * result.

- * This file defines various macros to transfer memory areas across

- * addresses. Thus, we need to be careful not to let the user to
- * trick us into accessing kernel memory that would normally be
- * inaccessible. This code is also fairly performance sensitive,
- * so we want to spend as little time doing safety checks as

- *
- * To make matters a bit more interesting, these macros sometimes also
- * called from within the kernel itself, in which case the address
- * validity check must be skipped. The get_fs() macro tells us what
- * to do: if get_fs()==USER_DS, checking is performed, if
- * get_fs()==KERNEL_DS, checking is bypassed.
- *
- * Note that even if the memory area specified by the user is in a
- * valid address range, it is still possible that we'll get a page
- * fault while accessing it. This is handled by filling out an
- * exception handler fixup entry for each instruction that has the
- * potential to fault. When such a fault occurs, the page fault
- * handler checks to see whether the faulting instruction has a fixup
- * associated and, if so, sets r8 to -EFAULT and clears r9 to 0 and
- * then resumes execution at the continuation point.

- * Addressing Terminology
- *
- * M - The low M bits of a physical address represent the offset
- * into the blade local memory. RAM memory on a blade is physically
- * contiguous (although various IO spaces may punch holes in
- * it)..
- *
- * N - Number of bits in the node portion of a socket physical
- * address.
- *
- * NASID - network ID of a router, Mbrick or Cbrick. Nasid values of
- * routers always have low bit of 1, C/MBricks have low bit
- * equal to 0. Most addressing macros that target UV hub chips
- * right shift the NASID by 1 to exclude the always-zero bit.
- * NASIDs contain up to 15 bits.
- *
- * GNODE - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
- * of nasids.
- *
- * PNODE - the low N bits of the GNODE. The PNODE is the most useful variant
- * of the nasid for socket usage.
- *
- *
- * NumaLink Global Physical Address Format:
- * +--------------------------------+---------------------+
- * |00..000| GNODE | NodeOffset |
- * +--------------------------------+---------------------+
- * |<-------53 - M bits --->|<--------M bits ----->

- * |00..000000000000| PNODE | NodeOffset |

- * <--- N bits --->|<--------M bits ----->
- *
- * M - number of node offset bits (35 .. 40)
- * N - number of PNODE bits (0 .. 10)
- *
- * Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64).

- * We get here for syscalls that don't have a lightweight
- * handler. For those, we need to bubble down into the kernel
- * and that requires setting up a minimal pt_regs structure,
- * and initializing the CPU state more or less as if an
- * interruption had occurred. To make syscall-restarts work,
- * we setup pt_regs such that cr_iip points to the second
- * instruction in syscall_via_break. Decrementing the IP
- * hence will restart the syscall via break and not
- * decrementing IP will return us to the caller, as usual.
- * Note that we preserve the value of psr.pp rather than
- * initializing it from dcr.pp. This makes it possible to
- * distinguish fsyscall execution from other privileged
- * execution.
- *
- * On entry:
- * - normal fsyscall handler register usage, except
- * that we also have:
- * - r18: address of syscall entry point
- * - r21: ar.fpsr
- * - r26: ar.pfs
- * - r27: ar.rsc
- * - r29: psr
- *
- * We used to clear some PSR bits here but that requires slow
- * serialization. Fortunately, that isn't really necessary.
- * The rationale is as follows: we used to clear bits
- * ~PSR_PRESERVED_BITS in PSR.L. Since
- * PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
- * ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
- * However,
- *
- * PSR.BE : already is turned off in __kernel_syscall_via_epc()
- * PSR.AC : don't care (kernel normally turns PSR.AC on)
- * PSR.I : already turned off by the time fsys_bubble_down gets
- * invoked
- * PSR.DFL: always 0 (kernel never turns it on)
- * PSR.DFH: don't care --- kernel never touches f32-f127 on its own
- * initiative
- * PSR.DI : always 0 (kernel never turns it on)
- * PSR.SI : always 0 (kernel never turns it on)
- * PSR.DB : don't care --- kernel never enables kernel-level
- * breakpoints
- * PSR.TB : must be 0 already; if it wasn't zero on entry to
- * __kernel_syscall_via_epc, the branch to fsys_bubble_down
- * will trigger a taken branch; the taken-trap-handler then
- * converts the syscall into a break-based system-call.

- * of the machine state. After returning from the signal handler, we return
- * control to the previous context by executing a sigreturn system call. A signal
- * handler may call the rt_sigreturn() function to directly return to a given
- * sigcontext. However, the user-level sigreturn() needs to do much more than

-/*
- * Here is what the interrupt logic between a PCI device and the kernel looks
- * like:
- *
- * (1) A PCI device raises one of the four interrupt pins (INTA, INTB, INTC,
- * INTD). The device is uniquely identified by its bus-, and slot-number
- * (the function number does not matter here because all functions share
- * the same interrupt lines).
- *
- * (2) The motherboard routes the interrupt line to a pin on a IOSAPIC
- * controller. Multiple interrupt lines may have to share the same
- * IOSAPIC pin (if they're level triggered and use the same polarity).
- * Each interrupt line has a unique Global System Interrupt (GSI) number
- * which can be calculated as the sum of the controller's base GSI number
- * and the IOSAPIC pin number to which the line connects.
- *
- * (3) The IOSAPIC uses an internal routing table entries (RTEs) to map the
- * IOSAPIC pin into the IA-64 interrupt vector. This interrupt vector is then
- * sent to the CPU.
- *
- * (4) The kernel recognizes an interrupt as an IRQ. The IRQ interface is
- * used as architecture-independent interrupt handling mechanism in Linux.
- * As an IRQ is a number, we have to have
- * IA-64 interrupt vector number <-> IRQ number mapping. On smaller
- * systems, we use one-to-one mapping between IA-64 vector and IRQ.
- *
- * To sum up, there are three levels of mappings involved:
- *
- * PCI pin -> global system interrupt (GSI) -> IA-64 vector <-> IRQ
- *
- * Note: The term "IRQ" is loosely used everywhere in Linux kernel to
- * describe interrupts. Now we use "IRQ" only for Linux IRQ's. ISA IRQ
- * (isa_irq) is the only exception in this source code.

- * This file defines the interruption vector table used by the CPU.
- * It does not include one entry per possible cause of interruption.
- *
- * The first 20 entries of the table contain 64 bundles each while the
- * remaining 48 entries contain only 16 bundles each.
- *
- * The 64 bundles are used to allow inlining the whole handler for critical
- * interruptions like TLB misses.
- *
- * For each entry, the comment is as follows:
- *
- * // 0x1c00 Entry 7 (size 64 bundles) Data Key Miss (12,51)
- * entry offset ----/ / / / /
- * entry number ---------/ / / /
- * size of the entry -------------/ / /
- * vector name -------------------------------------/ /
- * interruptions triggering this vector ----------------------/
- *
- * The table is 32KB in size and must be aligned on 32KB boundary.
- * (The CPU ignores the 15 lower bits of the address)
- *
- * Table is based upon EAS2.6 (Oct 1999)

-// The OS to SAL section of struct ia64_sal_os_state is set to a default

-// In addition to the SAL to OS state, this routine saves all the

-// excluding those that are already in the PAL minstate area. This
-// results in a partial pt_regs and switch_stack, the C code copies the
-// remaining registers from PAL minstate to pt_regs and switch_stack. The

- * Synchronize ar.itc of the current (slave) CPU with the ar.itc of the MASTER CPU
- * (normally the time-keeper CPU). We use a closed loop to eliminate the possibility of
- * unaccounted-for errors (such as getting a machine check in the middle of a calibration
- * step). The basic idea is for the slave to ask the master what itc value it has and to
- * read its own itc before and after the master responds. Each iteration gives us three
- * timestamps:
- *
- * slave master
- *
- * t0 ---\
- * ---\
- * --->
- * tm
- * /---
- * /---
- * t1 <---
- *
- *
- * The goal is to adjust the slave's ar.itc such that tm falls exactly half-way between t0
- * and t1. If we achieve this, the clocks are synchronized provided the interconnect
- * between the slave and the master is symmetric. Even if the interconnect were
- * asymmetric, we would still know that the synchronization error is smaller than the
- * roundtrip latency (t0 - t1).
- *
- * When the interconnect is quiet and symmetric, this lets us synchronize the itc to
- * within one or two cycles. However, we can only *guarantee* that the synchronization is
- * accurate to within a round-trip time, which is typically in the range of several
- * hundred cycles (e.g., ~500 cycles). In practice, this means that the itc's are usually
- * almost perfectly synchronized, but we shouldn't assume that the accuracy is much better

- * Therefore the operation reverts to a normal load
- *
- * ldX.c.nc (check load no clear):
- * - same as previous one
- *
- * ldX.c.clr.acq (ordered check load and clear):
- * - same as above for c.clr part. The load needs to have acquire semantics. So
- * we use the fence semantics which is stronger and thus ensures correctness.
- *
- * ldX.a (advanced load):
- * - suppose ldX.a r1=[r3]. If we get to the unaligned trap it's because the
- * address doesn't match requested size alignment. This means that we would
- * possibly need more than one load to get the result.
- *
- * The load part can be handled just like a normal load, however the difficult
- * part is to get the right thing into the ALAT. The critical piece of information
- * in the base address of the load & size. To do that, a ld.a must be executed,
- * clearly any address can be pushed into the table by using ld1.a r1=[r3]. Now
- * if we use the same target register, we will be okay for the check.a instruction.
- * If we look at the store, basically a stX [r3]=r1 checks the ALAT for any entry
- * which would overlap within [r3,r3+X] (the size of the load was store in the
- * ALAT). If such an entry is found the entry is invalidated. But this is not good
- * enough, take the following example:
- * r3=3
- * ld4.a r1=[r3]
- *
- * Could be emulated by doing:
- * ld1.a r1=[r3],1
- * store to temporary;
- * ld1.a r1=[r3],1
- * store & shift to temporary;
- * ld1.a r1=[r3],1
- * store & shift to temporary;
- * ld1.a r1=[r3]
- * store & shift to temporary;
- * r1=temporary
- *
- * So in this case, you would get the right value is r1 but the wrong info in
- * the ALAT. Notice that you could do it in reverse to finish with address 3
- * but you would still get the size wrong. To get the size right, one needs to
- * execute exactly the same kind of load. You could do it from a aligned
- * temporary location, but you would get the address wrong.
- *
- * So no matter what, it is not possible to emulate an advanced load
- * correctly. But is that really critical ?
- *
- * We will always convert ld.a into a normal load with ALAT invalidated. This
- * will enable compiler to do optimization where certain code path after ld.a
- * is not required to have ld.c/chk.a, e.g., code path with no intervening stores.
- *
- * If there is a store after the advanced load, one must either do a ld.c.* or
- * chk.a.* to reuse the value stored in the ALAT. Both can "fail" (meaning no
- * entry found in ALAT), and that's perfectly ok because:
- *
- * - ld.c.*, if the entry is not present a normal load is executed
- * - chk.a.*, if the entry is not present, execution jumps to recovery code
- *
- * In either case, the load can be potentially retried in another form.
- *
- * ALAT must be invalidated for the register (so that chk.a or ld.c don't pick
- * up a stale entry later). The register base update MUST also be performed.

- * This file implements call frame unwind support for the Linux
- * kernel. Parsing and processing the unwind information is
- * time-consuming, so this implementation translates the unwind
- * descriptors into unwind scripts. These scripts are very simple
- * (basically a sequence of assignments) and efficient to execute.
- * They are cached for later re-use. Each script is specific for a
- * given instruction pointer address and the set of predicate values
- * that the script depends on (most unwind descriptors are
- * unconditional and scripts often do not depend on predicates at
- * all). This code is based on the unwind conventions described in
- * the "IA-64 Software Conventions and Runtime Architecture" manual.
- *
- * SMP conventions:
- * o updates to the global unwind data (in structure "unw") are serialized
- * by the unw.lock spinlock
- * o each unwind script has its own read-write lock; a thread must acquire
- * a read lock before executing a script and must acquire a write lock
- * before modifying a script
- * o if both the unw.lock spinlock and a script's read-write lock must be
- * acquired, then the read-write lock must be acquired first.

-// The good point about this breakdown is that the long buffer handling

-// The reason for not using shifting & masking for both the head and the
-// tail is to stay semantically correct. This routine is not supposed
-// to write bytes outside of the buffer. While most of the time this would

-// of multithreaded code were to the extra bytes touched is actually owned

- * McKinley-optimized version of copy_page().
- *
- * Copyright (C) 2002 Hewlett-Packard Co
- * David Mosberger <davidm@hpl.hp.com>
- *
- * Inputs:
- * in0: address of target page
- * in1: address of source page
- * Output:
- * no return value
- *
- * General idea:
- * - use regular loads and stores to prefetch data to avoid consuming M-slot just for
- * lfetches => good for in-cache performance
- * - avoid l2 bank-conflicts by not storing into the same 16-byte bank within a single
- * cycle
- *
- * Principle of operation:
- * First, note that L1 has a line-size of 64 bytes and L2 a line-size of 128 bytes.
- * To avoid secondary misses in L2, we prefetch both source and destination with a line-size
- * of 128 bytes. When both of these lines are in the L2 and the first half of the
- * source line is in L1, we start copying the remaining words. The second half of the
- * source line is prefetched in an earlier iteration, so that by the time we start
- * accessing it, it's also present in the L1.
- *
- * We use a software-pipelined loop to control the overall operation. The pipeline
- * has 2*PREFETCH_DIST+K stages. The first PREFETCH_DIST stages are used for prefetching
- * source cache-lines. The second PREFETCH_DIST stages are used for prefetching destination
- * cache-lines, the last K stages are used to copy the cache-line words not copied by
- * the prefetches. The four relevant points in the pipelined are called A, B, C, D:
- * p[A] is TRUE if a source-line should be prefetched, p[B] is TRUE if a destination-line
- * should be prefetched, p[C] is TRUE if the second half of an L2 line should be brought
- * into L1D and p[D] is TRUE if a cacheline needs to be copied.
- *
- * This all sounds very complicated, but thanks to the modulo-scheduled loop support,
- * the resulting code is very regular and quite easy to follow (once you get the idea).
- *
- * As a secondary optimization, the first 2*PREFETCH_DIST iterations are implemented
- * as the separate .prefetch_loop. Logically, this loop performs exactly like the
- * main-loop (.line_copy), but has all known-to-be-predicated-off instructions removed,
- * so that each loop iteration is faster (again, good for cached case).
- *
- * When reading the code, it helps to keep the following picture in mind:
- *
- * word 0 word 1
- * +------+------+---
- * | v[x] | t1 | ^
- * | t2 | t3 | |
- * | t4 | t5 | |
- * | t6 | t7 | | 128 bytes
- * | n[y] | t9 | | (L2 cache line)
- * | t10 | t11 | |
- * | t12 | t13 | |
- * | t14 | t15 | v
- * +------+------+---
- *
- * Here, v[x] is copied by the (memory) prefetch. n[y] is loaded at p[C]
- * to fetch the second-half of the L2 cache line into L1, and the tX words are copied in
- * an order that avoids bank conflicts.

- // Here we handle the head & tail part when we check for alignment.
- // The following code handles only the load failures. The
- // main diffculty comes from the fact that loads/stores are
- // scheduled. So when you fail on a load, the stores corresponding
- // to previous successful loads must be executed.
- //
- // However some simplifications are possible given the way
- // things work.
- //
- // 1) HEAD
- // Theory of operation:
- //
- // Page A | Page B
- // ---------|-----
- // 1|8 x
- // 1 2|8 x
- // 4|8 x
- // 1 4|8 x
- // 2 4|8 x
- // 1 2 4|8 x
- // |1
- // |2 x
- // |4 x
- //
- // page_size >= 4k (2^12). (x means 4, 2, 1)
- // Here we suppose Page A exists and Page B does not.
- //
- // As we move towards eight byte alignment we may encounter faults.
- // The numbers on each page show the size of the load (current alignment).
- //
- // Key point:
- // - if you fail on 1, 2, 4 then you have never executed any smaller
- // size loads, e.g. failing ld4 means no ld1 nor ld2 executed
- // before.
- //
- // This allows us to simplify the cleanup code, because basically you
- // only have to worry about "pending" stores in the case of a failing
- // ld8(). Given the way the code is written today, this means only
- // worry about st2, st4. There we can use the information encapsulated
- // into the predicates.
- //
- // Other key point:
- // - if you fail on the ld8 in the head, it means you went straight
- // to it, i.e. 8byte alignment within an unexisting page.
- // Again this comes from the fact that if you crossed just for the ld8 then
- // you are 8byte aligned but also 16byte align, therefore you would
- // either go for the 16byte copy loop OR the ld8 in the tail part.
- // The combination ld1, ld2, ld4, ld8 where you fail on ld8 is impossible
- // because it would mean you had 15bytes to copy in which case you
- // would have defaulted to the byte by byte copy.
- //
- //
- // 2) TAIL
- // Here we now we have less than 16 bytes AND we are either 8 or 16 byte
- // aligned.
- //
- // Key point:
- // This means that we either:
- // - are right on a page boundary
- // OR
- // - are at more than 16 bytes from a page boundary with
- // at most 15 bytes to copy: no chance of crossing.
- //
- // This allows us to assume that if we fail on a load we haven't possibly
- // executed any of the previous (tail) ones, so we don't need to do
- // any stores. For instance, if we fail on ld2, this means we had
- // 2 or 3 bytes left to copy and we did not execute the ld8 nor ld4.
- //
- // This means that we are in a situation similar the a fault in the

-//
-// Theory of operations:
-// The goal is to go as quickly as possible to the point where
-// we can checksum 16 bytes/loop. Before reaching that point we must
-// take care of incorrect alignment of first byte.
-//
-// The code hereafter also takes care of the "tail" part of the buffer
-// before entering the core loop, if any. The checksum is a sum so it
-// allows us to commute operations. So we do the "head" and "tail"
-// first to finish at full speed in the body. Once we get the head and
-// tail values, we feed them into the pipeline, very handy initialization.
-//
-// Of course we deal with the special case where the whole buffer fits
-// into one 8 byte word. In this case we have only one entry in the pipeline.
-//
-// We use a (LOAD_LATENCY+2)-stage pipeline in the loop to account for
-// possible load latency and also to accommodate for head and tail.
-//
-// The end of the function deals with folding the checksum from 64bits
-// down to 16bits taking care of the carry.
-//
-// This version avoids synchronization in the core loop by also using a
-// pipeline for the accumulation of the checksum in resultx[] (x=1,2).
-//
-// wordx[] (x=1,2)
-// |---|
-// | | 0 : new value loaded in pipeline
-// |---|
-// | | - : in transit data
-// |---|
-// | | LOAD_LATENCY : current value to add to checksum
-// |---|
-// | | LOAD_LATENCY+1 : previous value added to checksum
-// |---| (previous iteration)
-//
-// resultx[] (x=1,2)
-// |---|
-// | | 0 : initial value
-// |---|
-// | | LOAD_LATENCY-1 : new checksum
-// |---|
-// | | LOAD_LATENCY : previous value of checksum
-// |---|
-// | | LOAD_LATENCY+1 : final checksum when out of the loop
-// |---|
-//
-//
-// See RFC1071 "Computing the Internet Checksum" for various techniques for
-// calculating the Internet checksum.
-//
-// NOT YET DONE:
-// - Maybe another algorithm which would take care of the folding at the
-// end in a different manner
-// - Work with people more knowledgeable than me on the network stack
-// to figure out if we could not split the function depending on the
-// type of packet or alignment we get. Like the ip_fast_csum() routine
-// where we know we have at least 20bytes worth of data to checksum.
-// - Do a better job of handling small packets.
-// - Note on prefetching: it was found that under various load, i.e. ftp read/write,
-// nfs read/write, the L1 cache hit rate is at 60% and L2 cache hit rate is at 99.8%
-// on the data that buffer points to (partly because the checksum is often preceded by
-// a copy_from_user()). This finding indiate that lfetch will not be beneficial since
-// the data is already in the cache.

- The algorithm is fairly straightforward: set byte by byte until we
- we get to a 16B-aligned address, then loop on 128 B chunks using an
- early store as prefetching, then loop on 32B chucks, then clear remaining
- words, finally clear remaining bytes.
- Since a stf.spill f0 can store 16B in one go, we use this instruction

-//
-//
-// This is an enhanced version of the basic strlen. it includes a combination
-// of compute zero index (czx), parallel comparisons, speculative loads and
-// loop unroll using rotating registers.
-//
-// General Ideas about the algorithm:
-// The goal is to look at the string in chunks of 8 bytes.
-// so we need to do a few extra checks at the beginning because the
-// string may not be 8-byte aligned. In this case we load the 8byte
-// quantity which includes the start of the string and mask the unused
-// bytes with 0xff to avoid confusing czx.
-// We use speculative loads and software pipelining to hide memory
-// latency and do read ahead safely. This way we defer any exception.
-//
-// Because we don't want the kernel to be relying on particular
-// settings of the DCR register, we provide recovery code in case
-// speculation fails. The recovery code is going to "redo" the work using
-// only normal loads. If we still get a fault then we generate a
-// kernel panic. Otherwise we return the strlen as usual.
-//
-// The fact that speculation may fail can be caused, for instance, by
-// the DCR.dm bit being set. In this case TLB misses are deferred, i.e.,
-// a NaT bit will be set if the translation is not present. The normal
-// load, on the other hand, will cause the translation to be inserted
-// if the mapping exists.
-//
-// It should be noted that we execute recovery code only when we need
-// to use the data that has been speculatively loaded: we don't execute
-// recovery code on pure read ahead data.
-//
-// Remarks:
-// - the cmp r0,r0 is used as a fast way to initialize a predicate
-// register to 1. This is required to make sure that we get the parallel
-// compare correct.
-//
-// - we don't use the epilogue counter to exit the loop but we need to set
-// it to zero beforehand.
-//
-// - after the loop we must test for Nat values because neither the
-// czx nor cmp instruction raise a NaT consumption fault. We must be
-// careful not to look too far for a Nat for which we don't care.
-// For instance we don't need to look at a NaT in val2 if the zero byte
-// was in val1.
-//
-// - Clearly performance tuning is required.

- kexec is a system call that implements the ability to shutdown your
- current kernel, and to start another kernel. It is like a reboot
- but it is independent of the system firmware. And like a reboot
- you can start any kernel with it, not just Linux.
-
- The name comes from the similarity to the exec system call.
-
- It is an ongoing process to be certain the hardware in a machine
- is properly shutdown, so do not be surprised if this code does not
- initially work for you. As of this writing the exact hardware
- interface is strongly in flux, so no good recommendation can be
- made.

- It is an ongoing process to be certain the hardware in a machine
- is properly shutdown, so do not be surprised if this code does not
- initially work for you. As of this writing the exact hardware
- interface is strongly in flux, so no good recommendation can be
- made.

-config CRASH_DUMP
- bool "Kernel crash dumps"
- help
- Generate crash dump after being started by kexec.
- This should be normally only set in special crash dump kernels
- which are loaded in the main kernel with kexec-tools into
- a specially reserved region and then later executed after
- a crash by kdump/kexec. The crash dump kernel must be compiled
- to a memory address not used by the main kernel or firmware using
- PHYSICAL_START.

+# This module implements support for AES instructions as per PowerISA
+# specification version 2.07, first implemented by POWER8 processor.
+# The module is endian-agnostic in sense that it supports both big-
+# and little-endian cases. Data alignment in parallelizable modes is
+# handled with VSX loads and stores, which implies MSR.VSX flag being
+# set. It should also be noted that ISA specification doesn't prohibit
+# alignment exceptions for these instructions on page boundaries.
+# Initially alignment was handled in pure AltiVec/VMX way [when data
+# is aligned programmatically, which in turn guarantees exception-
+# free execution], but it turned to hamper performance when vcipher
+# instructions are interleaved. It's reckoned that eventual
+# misalignment penalties at page boundaries are in average lower
+# than additional overhead in pure AltiVec approach.
+#
+# May 2016
+#
+# Add XTS subroutine, 9x on little- and 12x improvement on big-endian
+# systems were measured.

+####################### WARNING: Here be dragons! #######################
+#
+# This code is written as 'ctr32', based on a 32-bit counter used
+# upstream. The kernel does *not* use a 32-bit counter. The kernel uses
+# a 128-bit counter.
+#
+# This leads to subtle changes from the upstream code: the counter
+# is incremented with vaddu_q_m rather than vaddu_w_m. This occurs in
+# both the bulk (8 blocks at a time) path, and in the individual block
+# path. Be aware of this when doing updates.
+#
+# See:
+# 1d4aa0b4c181 ("crypto: vmx - Fixing AES-CTR counter bug")

+ * We use a flag to track in-kernel Vector context. Currently the flag has the
+ * following meaning:
+ *
+ * - bit 0: indicates whether the in-kernel Vector context is active. The
+ * activation of this state disables the preemption. On a non-RT kernel, it
+ * also disable bh.
+ * - bits 8: is used for tracking preemptible kernel-mode Vector, when
+ * RISCV_ISA_V_PREEMPTIVE is enabled. Calling kernel_vector_begin() does not
+ * disable the preemption if the thread's kernel_vstate.datap is allocated.
+ * Instead, the kernel set this bit field. Then the trap entry/exit code
+ * knows if we are entering/exiting the context that owns preempt_v.
+ * - 0: the task is not using preempt_v
+ * - 1: the task is actively using preempt_v. But whether does the task own
+ * the preempt_v context is decided by bits in RISCV_V_CTX_DEPTH_MASK.
+ * - bit 16-23 are RISCV_V_CTX_DEPTH_MASK, used by context tracking routine
+ * when preempt_v starts:
+ * - 0: the task is actively using, and own preempt_v context.
+ * - non-zero: the task was using preempt_v, but then took a trap within.
+ * Thus, the task does not own preempt_v. Any use of Vector will have to
+ * save preempt_v, if dirty, and fallback to non-preemptible kernel-mode
+ * Vector.
+ * - bit 30: The in-kernel preempt_v context is saved, and requries to be
+ * restored when returning to the context that owns the preempt_v.
+ * - bit 31: The in-kernel preempt_v context is dirty, as signaled by the
+ * trap entry code. Any context switches out-of current task need to save
+ * it to the task's in-kernel V context. Also, any traps nesting on-top-of
+ * preempt_v requesting to use V needs a save.

- * The canonical order of ISA extension names in the ISA string is defined in

- *
- * Ordinarily, for in-kernel data structures, this order is unimportant but
- * isa_ext_arr defines the order of the ISA string in /proc/cpuinfo.
- *
- * The specification uses vague wording, such as should, when it comes to
- * ordering, so for our purposes the following rules apply:
- *
- * 1. All multi-letter extensions must be separated from other extensions by an
- * underscore.
- *
- * 2. Additional standard extensions (starting with 'Z') must be sorted after
- * single-letter extensions and before any higher-privileged extensions.
-
- * 3. The first letter following the 'Z' conventionally indicates the most
- * closely related alphabetical extension category, IMAFDQLCBKJTPVH.
- * If multiple 'Z' extensions are named, they must be ordered first by
- * category, then alphabetically within a category.
- *
- * 3. Standard supervisor-level extensions (starting with 'S') must be listed
- * after standard unprivileged extensions. If multiple supervisor-level
- * extensions are listed, they must be ordered alphabetically.
- *
- * 4. Standard machine-level extensions (starting with 'Zxm') must be listed
- * after any lower-privileged, standard extensions. If multiple
- * machine-level extensions are listed, they must be ordered
- * alphabetically.
- *
- * 5. Non-standard extensions (starting with 'X') must be listed after all
- * standard extensions. If multiple non-standard extensions are listed, they
- * must be ordered alphabetically.
- *
- * An example string following the order is:
- * rv64imadc_zifoo_zigoo_zafoo_sbar_scar_zxmbaz_xqux_xrux
- *
- * New entries to this struct should follow the ordering rules described above.

+ * If multiple 'Z' extensions are named, they must be ordered first by
+ * category, then alphabetically within a category.
+ *
+ * 3. Standard supervisor-level extensions (starting with 'S') must be listed
+ * after standard unprivileged extensions. If multiple supervisor-level
+ * extensions are listed, they must be ordered alphabetically.
+ *
+ * 4. Standard machine-level extensions (starting with 'Zxm') must be listed
+ * after any lower-privileged, standard extensions. If multiple
+ * machine-level extensions are listed, they must be ordered
+ * alphabetically.
+ *
+ * 5. Non-standard extensions (starting with 'X') must be listed after all
+ * standard extensions. If multiple non-standard extensions are listed, they
+ * must be ordered alphabetically.
+ *
+ * An example string following the order is:
+ * rv64imadc_zifoo_zigoo_zafoo_sbar_scar_zxmbaz_xqux_xrux
+ *
+ * New entries to this struct should follow the ordering rules described above.

- * The mechanism of our pfault code: if Linux is running as guest, runs a user

- * paged out we get a pfault interrupt.
- *
- * This allows us, within the guest, to schedule a different process. Without
- * this mechanism the host would have to suspend the whole virtual cpu until
- * the page has been paged in.
- *
- * So when we get such an interrupt then we set the state of the current task
- * to uninterruptible and also set the need_resched flag. Both happens within
- * interrupt context(!). If we later on want to return to user space we
- * recognize the need_resched flag and then call schedule(). It's not very
- * obvious how this works...
- *
- * Of course we have a lot of additional fun with the completion interrupt (->
- * host signals that a page of a process has been paged in and the process can
- * continue to run). This interrupt can arrive on any cpu and, since we have
- * virtual cpus, actually appear before the interrupt that signals that a page

- * A 2KB-pgtable is either upper or lower half of a normal page.
- * The second half of the page may be unused or used as another
- * 2KB-pgtable.
- *
- * Whenever possible the parent page for a new 2KB-pgtable is picked
- * from the list of partially allocated pages mm_context_t::pgtable_list.
- * In case the list is empty a new parent page is allocated and added to
- * the list.
- *
- * When a parent page gets fully allocated it contains 2KB-pgtables in both
- * upper and lower halves and is removed from mm_context_t::pgtable_list.
- *
- * When 2KB-pgtable is freed from to fully allocated parent page that
- * page turns partially allocated and added to mm_context_t::pgtable_list.
- *
- * If 2KB-pgtable is freed from the partially allocated parent page that
- * page turns unused and gets removed from mm_context_t::pgtable_list.
- * Furthermore, the unused parent page is released.
- *
- * As follows from the above, no unallocated or fully allocated parent
- * pages are contained in mm_context_t::pgtable_list.
- *
- * The upper byte (bits 24-31) of the parent page _refcount is used
- * for tracking contained 2KB-pgtables and has the following format:
- *
- * PP AA
- * 01234567 upper byte (bits 24-31) of struct page::_refcount
- * || ||
- * || |+--- upper 2KB-pgtable is allocated
- * || +---- lower 2KB-pgtable is allocated
- * |+------- upper 2KB-pgtable is pending for removal
- * +-------- lower 2KB-pgtable is pending for removal
- *
- * (See commit 620b4e903179 ("s390: use _refcount for pgtables") on why
- * using _refcount is possible).
- *
- * When 2KB-pgtable is allocated the corresponding AA bit is set to 1.
- * The parent page is either:
- * - added to mm_context_t::pgtable_list in case the second half of the
- * parent page is still unallocated;
- * - removed from mm_context_t::pgtable_list in case both hales of the
- * parent page are allocated;
- * These operations are protected with mm_context_t::lock.
- *
- * When 2KB-pgtable is deallocated the corresponding AA bit is set to 0
- * and the corresponding PP bit is set to 1 in a single atomic operation.
- * Thus, PP and AA bits corresponding to the same 2KB-pgtable are mutually
- * exclusive and may never be both set to 1!
- * The parent page is either:
- * - added to mm_context_t::pgtable_list in case the second half of the
- * parent page is still allocated;
- * - removed from mm_context_t::pgtable_list in case the second half of
- * the parent page is unallocated;
- * These operations are protected with mm_context_t::lock.
- *
- * It is important to understand that mm_context_t::lock only protects
- * mm_context_t::pgtable_list and AA bits, but not the parent page itself
- * and PP bits.
- *
- * Releasing the parent page happens whenever the PP bit turns from 1 to 0,
- * while both AA bits and the second PP bit are already unset. Then the
- * parent page does not contain any 2KB-pgtable fragment anymore, and it has
- * also been removed from mm_context_t::pgtable_list. It is safe to release
- * the page therefore.
- *
- * PGSTE memory spaces use full 4KB-pgtables and do not need most of the
- * logic described above. Both AA bits are set to 1 to denote a 4KB-pgtable
- * while the PP bits are never used, nor such a page is added to or removed
- * from mm_context_t::pgtable_list.

+ * - VEX-coded instructions

+ * - 256-bit vectors (2 AES blocks per vector)
+ * - EVEX-coded instructions
+ * - ymm0-ymm31
+ * - This is for CPUs that have AVX512 but where using zmm registers causes
+ * downclocking, and for CPUs that have AVX10/256 but not AVX10/512.
+ * - By "AVX10/256" we really mean (AVX512BW + AVX512VL) || AVX10/256.

+ * (4 AES blocks per vector) in zmm0-zmm31.
+ * - This is for CPUs that have good AVX512 or AVX10/512 support.
+ *
+ * This file doesn't have an implementation for AES-NI alone (without AVX), as
+ * the lack of VEX would make all the assembly code different.
+ *
+ * When we use VAES, we also use VPCLMULQDQ to parallelize the computation of
+ * the XTS tweaks. This avoids a bottleneck. Currently there don't seem to be
+ * any CPUs that support VAES but not VPCLMULQDQ. If that changes, we might
+ * need to start also providing an implementation using VAES alone.
+ *
+ * The AES-XTS implementations in this file support everything required by the
+ * crypto API, including support for arbitrary input lengths and multi-part
+ * processing. However, they are most heavily optimized for the common case of
+ * power-of-2 length inputs that are processed in a single part (disk sectors).

+ * vector 0x80 and calling int80_is_external() is not merely
+ * suboptimal but actively incorrect: it could cause a system call
+ * to be incorrectly ignored.
+ *
+ * 2) It is called only for handling vector 0x80 of event type
+ * EVENT_TYPE_SWINT and will never be called to handle any external
+ * interrupt (event type EVENT_TYPE_EXTINT).
+ *
+ * 3) FRED has separate entry flows depending on if the event came from
+ * user space or kernel space, and because the kernel does not use
+ * INT insns, the FRED kernel entry handler fred_entry_from_kernel()
+ * falls through to fred_bad_type() if the event type is
+ * EVENT_TYPE_SWINT, i.e., INT insns. So if the kernel is handling
+ * an INT insn, it can only be from a user level.
+ *
+ * 4) int80_emulation() does a CLEAR_BRANCH_HISTORY. While FRED will
+ * likely take a different approach if it is ever needed: it
+ * probably belongs in either fred_intx()/ fred_other() or
+ * asm_fred_entrypoint_user(), depending on if this ought to be done

- *
- * This is considered a slow path. It is not used by most libc
- * implementations on modern hardware except during process startup.

- * eax system call number
- * ebx arg1
- * ecx arg2
- * edx arg3
- * esi arg4
- * edi arg5
- * ebp arg6
+ * int 0x80 is used by 32 bit mode as a system call entry. Normally idt entries

+ * 2.During posted MSI processing, the CPU needs to do 64-bit read and xchg
+ * for checking and clearing posted interrupt request (PIR), a 256 bit field
+ * within the PID.
+ * 3.On the other side, the IOMMU does atomic swaps of the entire PID cache
+ * line when posting interrupts and setting control bits.
+ * 4.The CPU can access the cache line a magnitude faster than the IOMMU.
+ * 5.Each time the IOMMU does interrupt posting to the PIR will evict the PID
+ * cache line. The cache line states after each operation are as follows:
+ * CPU IOMMU PID Cache line state
+ * ---------------------------------------------------------------
+ *...read64 exclusive
+ *...lock xchg64 modified
+ *... post/atomic swap invalid
+ *...-------------------------------------------------------------
+ *
+ * To reduce L1 data cache miss, it is important to avoid contention with
+ * IOMMU's interrupt posting/atomic swap. Therefore, a copy of PIR is used
+ * to dispatch interrupt handlers.
+ *
+ * In addition, the code is trying to keep the cache line state consistent
+ * as much as possible. e.g. when making a copy and clearing the PIR
+ * (assuming non-zero PIR bits are present in the entire PIR), it does:
+ * read, read, read, read, xchg, xchg, xchg, xchg

+ *
+ * READ_ONCE(ssp); // read+discard top element on stack
+ * ssp += nr_to_pop * 8; // move the shadow stack
+ * READ_ONCE(ssp-8); // read+discard last popped stack element
