* ArmVirtPkg/MemoryInitPeiLib: split memory HOB based on MAX_ALLOC_ADDRESSArd Biesheuvel2018-12-201-4/+4
| | | | | | | | | | | | | | | | | | The current ArmVirtMemoryInitPeiLib code splits the memory region passed via PcdSystemMemoryBase/PcdSystemMemorySize in two if the region extends beyond the MAX_ADDRESS limit. This was introduced for 32-bit ARM, which may support more than 4 GB of physical address space, but cannot address all of it via a 1:1 mapping, and a single region that is not mappable in its entirety is unusable by the PEI core. AArch64 is in a similar situation now: platforms may support more than 256 TB of physical address space, but only 256 TB is addressable by the CPU, and so a memory region that extends from below this limit to above it should be split.

| | | | | | | | | | | | | | | | | Commit 9a67ba261fe9 ("ArmVirtPkg: Replace obsoleted network drivers from platform DSC/FDF") incorrectly added the BaseCryptLib, OpensslLib and IntrinsicLib to "ArmVirtPkg/ArmVirtQemuKernel.dsc", it's redundant and the library instances from "ArmVirt.dsc.inc" is already sufficient.

| | | | | | | | | | | | | Commit 9a67ba261fe9 ("ArmVirtPkg: Replace obsoleted network drivers from platform DSC/FDF") failed to take into account that the now unconditionally included IScsiDxe.inf from NetworkPkg requires a resolution for TcpIoLib. Since specifying such a resolution is harmless for platforms that have no networking enabled, let's just fix things by dropping the conditionals around it.

* ArmVirtPkg/PrePiUniCoreRelocatable CLANG38: work around build issuesArd Biesheuvel2018-12-114-5/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The self-relocating PrePi module that is used by the ArmVirtQemuKernel and ArmVirtXen targets runs the linker in PIE mode so that it emits dynamic relocations into the final image in a way that permits the module to relocate itself into place before calling into the C code. When building these targets using the CLANG38 toolchain, we switch from the BFD to the GOLD linker, which behaves a bit differently when building PIE executables, and insists on emitting GOT indirected symbol references throughout, which means a) that we end up with absolute addresses (which need to be fixed up at load time) for no good reason, and b) we have to add support for handling GOT entries to GenFw if we want to convert them into PE/COFF. So instead, let's emit a shared library. Since the ELF image only serves as the input to GenFw, this does not lead to any loss of functionality, although it does require the -Bsymbolic linker option to be added to ensure that no symbol based dynamic relocations are emitted (which would, e.g., permit lazy binding for shared libraries). So for all other toolchains, the linker option changes are a no-op. Then, we have to convince CLANG38/GOLD that there is no need to refer to symbols via a GOT entry. This is done by forcing hidden visibility for all symbols in all components that make up the PrePi SEC module: this informs the linker that a symbol is never exported or preempted, making it safe to refer to it directly from anywhere in the code, rather than indirectly via a GOT entry.

Given that the first page of the flash device is not actually used anyway, let's reduce the mappings of the peripheral space and the flash device (both of which cover page #0) to only cover what is actually required: ArmVirtQemu.fdf: > 0x00001000|0x001ff000 > gArmTokenSpaceGuid.PcdFvBaseAddress|gArmTokenSpaceGuid.PcdFvSize ArmVirtQemuKernel.fdf: > 0x00008000|0x001f8000 > gArmTokenSpaceGuid.PcdFvBaseAddress|gArmTokenSpaceGuid.PcdFvSize For ArmVirtQemu, the resulting virtual mapping looks roughly like: - [0, 4K) : flash, unmapped - [4K, 2M) : flash, mapped as WB+X RAM - [2M, 64M) : flash, unmapped - [64M, 128M) : varstore flash, will be mapped by the NOR flash driver - [128M, 256M) : peripherals, mapped as device - [256M, 1GB) : 32-bit MMIO aperture, translated IO aperture, ECAM, will be mapped by the PCI host bridge driver - [1GB, ...) : RAM, mapped. After this change, any inadvertent read or write from/to the first physical page will trigger a translation fault inside the guest, regardless of the nature of the instruction, without crashing QEMU.

| | | | | | | | | | | | | | | | | | The primary FV contains the firmware boot image, which is not runtime updatable in our case. So exposing it to the NOR flash driver is undesirable, since it may attempt to modify the NOR flash contents. It is also rather pointless, since we don't keep anything there that we care to expose. (the SEC and PEI phase modules are not executable from DXE context, and the contents of the embedded DXE phase FV are exposed by the DXE core directly via the FVB2 protocol) So let's disregard the NOR flash block that covers the primary FV.

| | | | | | | | | | | | | | | | | Currently, we map DRAM as EFI_MEMORY_WB, and the remainder of the entire virtual address space is mapped with EFI_MEMORY_UC attributes, regardless of whether any devices actually reside there. Now that we are relaxing the address space limit to more than 40 bits, mapping all that address space actually takes up more space in page tables than we have so far made available as temporary RAM. So let's get rid of the mapping rather than increasing the available RAM, given that the mapping is not particularly useful anyway.

| | | | | | | | | | | | | | | | | | | | Up until now, we have been getting away with not declaring the ECAM and translated I/O spaces at all in the GCD memory map, simply because we map the entire address space with device attributes in the early PEI code, and so the ECAM space will be mapped wherever it ends up. Now that we are about to make changes to how ArmVirtQemu reasons about the size of the address space, it would be better to get rid of this mapping of the entire address space, since it can get arbitrarily large without real benefit. So start by mapping the ECAM and translated I/O spaces explicitly, instead of relying on the early PEI mapping.

* ArmVirtPkg/NorFlashQemuLib: discover NOR flash banks dynamicallyArd Biesheuvel2018-11-262-21/+69
| | | | | | | | | | | | | | | | | | | | | | | | NorFlashQemuLib is one of the last remaining drivers in ArmVirtPkg that are not based on the device tree received from QEMU. For ArmVirtQemu, this does not really matter, given that the NOR flash banks are always the same: the PEI code is linked to execute in place from flash bank #0, and the fixed varstore PCDs refer to flash bank #1 directly. However, ArmVirtQemuKernel can execute at any offset, permitting it to be used as an intermediary loader when running QEMU with secure world emulation enabled, in which case NOR flash bank #0 is secure only and contains the secure world firmware. In this case, NorFlashQemuLib should not expose the first flash bank at all. To prevent introducing too much internal knowledge about which flash bank is accessible under which circumstances, let's switch to using the DTB to decide which flash banks to expose to the NOR flash driver.

Some explanation should be in order (because 5c3481b0b611e doesn't offer any): - The UefiDevicePathLibDevicePathProtocol instance uses the Device Path Utilities Protocol, produced by DevicePathDxe, for formatting and parsing the textual device path representation. This allows for a lighter weight lib instance that gets linked into several DXE modules. In comparison, the more standalone UefiDevicePathLib instance includes the formatting and parsing routines in every client module. - The DXE core needs DevicePathLib before it dispatches DevicePathDxe, so it needs to stick with the standalone instance. - DevicePathDxe itself also needs the standalone instance, for implementing the protocol. - The DXE-phase PCD driver, "MdeModulePkg/Universal/PCD/Dxe/Pcd.inf", depends on DevicePathLib via UefiLib and DxeServicesLib at the least; so with this update, it inherits a dependency on the protocol. In reverse, DevicePathDxe depends on the PCD Protocol, via PcdLib. The cycle is broken by using BasePcdLibNull in DevicePathDxe. That restricts it to FixedAtBuild, Patch, and FeatureFlag PCDs, but that's fine. Example space savings (using ArmVirtQemu and the GCC5 toolchain): - NOOPT: 187KB in FVMAIN, 12KB in FVMAIN_COMPACT - DEBUG: 147KB in FVMAIN, 20KB in FVMAIN_COMPACT - RELEASE: 123KB in FVMAIN, 17KB in FVMAIN_COMPACT Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Julien Grall <julien.grall@linaro.org> Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=940 Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
* ArmVirtPkg: reinstate timer unmask quirk for XenArd Biesheuvel2018-04-263-0/+180
| | | | | | | | | | | | | | | | | | | | Commit 411a373ed642 ("ArmPkg/TimerDxe: remove workaround for KVM timer handling") removed the virtual timer handling quirk that cleared the mask bit in the control register when enabling the timer, under the assumption that only ancient KVM host implementations required it. However, Julien reports that Xen also masks the timer interrupt in the guest view of the timer control register, and therefore needs the same quirk. So let's reinstate it, but using a Xen specific implementation of the timer support library, so that other virt platforms remain unchanged.

* ArmVirtPkg: create QemuVirtMemInfoLib version for ArmVirtQemuArd Biesheuvel2017-11-233-0/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QemuVirtMemInfoLib ArmVirtMemInfoLib implementation created for ArmVirtQemuKernel does exactly what we need for ArmVirtQemu, the only difference being that the latter is PrePeiCore based, and so it uses a different method to ensure that PcdSystemMemorySize is set when ArmVirtGetMemoryMap() is called. On ArmVirtQemu, we currently abuse the implied ordering guarantees provided by ArmPlatformLib, by implementing this as follows: ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.inf [ArmVirtPkg/ArmVirtQemu.dsc] InitializeMemory() [ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.c] ArmPlatformInitializeSystemMemory() [ArmVirtPkg/Library/ArmVirtPlatformLib/Virt.c] // // set PcdSystemMemorySize from the DT // MemoryPeim() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] InitMmu() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] ArmPlatformGetVirtualMemoryMap() [ArmVirtPkg/Library/ArmVirtPlatformLib/VirtMem.c] // // consume PcdSystemMemorySize // Given that we are trying to get rid of ArmPlatformLib, or at least remove some of these API functions that are never used for their original purpose by any platforms, we need to move the PCD assignment elsewhere. So create a PEIM-only version of QemuVirtMemInfoLib especially for ArmVirtQemu, and add the PCD assignment code to its constructor.
