* Documentation: Document sysfs interfaces purr, spurr, idle_purr, idle_spurrGautham R. Shenoy2020-04-301-0/+39
| | | | | | | | | | | | Add documentation for the following sysfs interfaces: /sys/devices/system/cpu/cpuX/purr /sys/devices/system/cpu/cpuX/spurr /sys/devices/system/cpu/cpuX/idle_purr /sys/devices/system/cpu/cpuX/idle_spurr Signed-off-by: Gautham R.

* Documentation/powerpc: VAS APIHaren Myneni2020-04-202-0/+293
| | | | | | | | | | | | | Power9 introduced Virtual Accelerator Switchboard (VAS) which allows userspace to communicate with Nest Accelerator (NX) directly. But kernel has to establish channel to NX for userspace. This document describes user space API that application can use to establish communication channel.

* powerpc/vas: Define VAS_TX_WIN_OPEN ioctl APIHaren Myneni2020-04-201-0/+1
| | | | | | | | | | | Define the VAS_TX_WIN_OPEN ioctl interface for NX GZIP access from user space. This interface is used to open GZIP send window and mmap region which can be used by userspace to send requests to NX directly with copy/paste instructions.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EFI handover protocol was introduced on x86 to permit the boot loader to pass a populated boot_params structure as an additional function argument to the entry point. This allows the bootloader to pass the base and size of a initrd image, which is more flexible than relying on the EFI stub's file I/O routines, which can only access the file system from which the kernel image itself was loaded from firmware. This approach requires a fair amount of internal knowledge regarding the layout of the boot_params structure on the part of the boot loader, as well as knowledge regarding the allowed placement of the initrd in memory, and so it has been deprecated in favour of a new initrd loading method that is based on existing UEFI protocols and best practices. So update the x86 boot protocol documentation to clarify that the EFI handover protocol has been deprecated, and while at it, add a note that invoking the EFI handover protocol still requires the PE/COFF image to be loaded properly (as opposed to simply being copied into memory). Also, drop the code32_start header field from the list of values that need to be provided, as this is no longer required.

Provide a single switch LLVM=1 to use Clang and LLVM tools instead of GCC and Binutils. You can pass it from the command line or as an environment variable. Please note LLVM=1 does not turn on the integrated assembler. You need to pass LLVM_IAS=1 to use it. When the upstream kernel is ready for the integrated assembler, I think we can make it default. We discussed what we need, and we agreed to go with a simple boolean flag that switches both target and host tools: https://lkml.org/lkml/2020/3/28/494 https://lkml.org/lkml/2020/4/3/43 Some items discussed, but not adopted: - LLVM_DIR When multiple versions of LLVM are installed, I just thought supporting LLVM_DIR=/path/to/my/llvm/bin/ might be useful. CC = $(LLVM_DIR)clang LD = $(LLVM_DIR)ld.lld ... However, we can handle this by modifying PATH. So, we decided to not do this. - LLVM_SUFFIX Some distributions (e.g. Debian) package specific versions of LLVM with naming conventions that use the version as a suffix. CC = clang$(LLVM_SUFFIX) LD = ld.lld(LLVM_SUFFIX) ... will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc., but the suffixed versions in /usr/bin/ are symlinks to binaries in /usr/lib/llvm-#/bin/, so this can also be handled by PATH.

According to Arvind: binutils-2.21 and -2.22. An x86-64 defconfig will fail with Invalid absolute R_X86_64_32S relocation: _etext and after fixing that one, with Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve Those two versions of binutils have a bug when it comes to handling symbols defined outside of a section and binutils 2.23 has the proper fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html Therefore, up to the fixed version directly, skipping the broken ones.

However it actually works only at early stages of the system loading, when the majority of memory is free. After some time the memory gets fragmented by non-movable pages, so the chances to find a contiguous 1GB block are getting close to zero. Even dropping caches manually doesn't help a lot. At large scale rebooting servers in order to allocate gigantic hugepages is quite expensive and complex. At the same time keeping some constant percentage of memory in reserved hugepages even if the workload isn't using it is a big waste: not all workloads can benefit from using 1 GB pages. The following solution can solve the problem: 1) On boot time a dedicated cma area* is reserved. The size is passed as a kernel argument. 2) Run-time allocations of gigantic hugepages are performed using the cma allocator and the dedicated cma area In this case gigantic hugepages can be allocated successfully with a high probability, however the memory isn't completely wasted if nobody is using 1GB hugepages: it can be used for pagecache, anon memory, THPs, etc. * On a multi-node machine a per-node cma area is allocated on each node. Following gigantic hugetlb allocation are using the first available numa node if the mask isn't specified by a user. Usage: 1) configure the kernel to allocate a cma area for hugetlb allocations: pass hugetlb_cma=10G as a kernel argument 2) allocate hugetlb pages as usual, e.g. echo 10 > /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages If the option isn't enabled or the allocation of the cma area failed, the current behavior of the system is preserved. x86 and arm-64 are covered by this patch, other architectures can be trivially added later. The patch contains clean-ups and fixes proposed and implemented by Aslan Bakirov and Randy Dunlap. It also contains ideas and suggestions proposed by Rik van Riel, Michal Hocko and Mike Kravetz.
