[RFC][PATCH] selftests/vm/transhuge-stress: fix ram size thinko

by George G. Davis

From: "George G. Davis" <davis.george(a)siemens.com> When executing transhuge-stress with an argument to specify the virtual memory size for testing, the ram size is reported as 0, e.g. transhuge-stress 384 thp-mmap: allocate 192 transhuge pages, using 384 MiB virtual memory and 0 MiB of ram thp-mmap: 0.184 s/loop, 0.957 ms/page, 2090.265 MiB/s 192 succeed, 0 failed This appears to be due to a thinko in commit 0085d61fe05e ("selftests/vm/transhuge-stress: stress test for memory compaction"), where, at a guess, the intent was to base "xyz MiB of ram" on `ram` size. Here are results after using `ram` size: thp-mmap: allocate 192 transhuge pages, using 384 MiB virtual memory and 14 MiB of ram Fixes: 0085d61fe05e ("selftests/vm/transhuge-stress: stress test for memory compaction") Signed-off-by: George G.

[PATCH v1] selftests/vm: make MADV_POPULATE_(READ|WRITE) use in-tree headers

by David Hildenbrand

The madv_populate selftest currently builds with a warning when the local installed headers (via the distribution) don't include MADV_POPULATE_READ and MADV_POPULATE_WRITE. The warning is correct, because the test cannot locate the necessary header. Reason is that the in-tree installed headers (usr/include) have a "linux" instead of a "sys" subdirectory. Including "linux/mman.h" instead of "sys/mman.h" doesn't work (e.g., mmap() and madvise() are not defined that way). The only thing that seems to work is including "linux/mman.h" in addition to "sys/mman.h". We can get rid of our availability check and simplify.

selftests/vm madv_populate.c test

by Shuah Khan

Hi David, I am running into the following warning when try to build this test: madv_populate.c:334:2: warning: #warning "missing MADV_POPULATE_READ or MADV_POPULATE_WRITE definition" [-Wcpp] 334 | #warning "missing MADV_POPULATE_READ or MADV_POPULATE_WRITE definition" | ^~~~~~~ I see that the following handling is in place. However there is no other information to explain why the check is necessary. #if defined(MADV_POPULATE_READ) && defined(MADV_POPULATE_WRITE) #else /* defined(MADV_POPULATE_READ) && defined(MADV_POPULATE_WRITE) */ #warning "missing MADV_POPULATE_READ or MADV_POPULATE_WRITE definition" I do see these defined in: include/uapi/asm-generic/mman-common.h:#define MADV_POPULATE_READ 22 include/uapi/asm-generic/mman-common.h:#define MADV_POPULATE_WRITE 23 Is this the case of missing include from madv_populate.c? thanks, -- Shuah

[PATCH v1 00/38] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - KVM is not currently supported and we depend on !KVM, in hopefully the next version I will add support for coexisting with KVM and then in a subsequent series implement real support for KVM guests. - It is likely some build configurations have issues, I've not fully checked this yet. In general testing is still ongoing, I anticipate finding and fixing some issues in the implementation. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. Due to dependencies on kselftest changes already upstreamed this series is based on for-next/kselftest in the arm64 tree.
