[PATCH v3 5/5] selftests/pfru: add test for Platform Firmware Runtime Update and Telemetry

by Chen Yu

Introduce a simple test for Platform Firmware Runtime Update and Telemetry drivers. It is based on ioctl to either update firmware driver or code injection, and read corresponding PFRU Telemetry log into user space. For example: ./pfru_test -h usage: pfru_test [OPTIONS] code injection: -l, --load -s, --stage -a, --activate -u, --update [stage and activate] -q, --query -d, --revid update telemetry: -G, --getloginfo -T, --type(0:execution, 1:history) -L, --level(0, 1, 2, 4) -R, --read -D, --revid log ./pfru_test -G log_level:4 log_type:0 log_revid:2 max_data_size:65536 chunk1_size:0 chunk2_size:1401 rollover_cnt:0 reset_cnt:4 ./pfru_test -q code injection image type:794bf8b2-6e7b-454e-885f-3fb9bb185402 fw_version:0 code_rt_version:1 driver update image type:0e5f0b14-f849-7945-ad81-bc7b6d2bb245 drv_rt_version:0 drv_svn:0 platform id:39214663-b1a8-4eaa-9024-f2bb53ea4723 oem id:a36db54f-ea2a-e14e-b7c4-b5780e51ba3d launch the update: ./pfru_test -l yours.cap -u -T 1 -L 4 Tested-by: Dou Shengnan <shengnanx.dou(a)intel.com> Signed-off-by: Chen Yu <yu.c.chen(a)intel.com> --- v3: No change since v2. v2: Do not allow non-root user to run this test. (Shuah Khan) Test runs on platform without pfru_telemetry should skip instead of reporting failure/error. (Shuah Khan) Reuse uapi/linux/pfru.h instead of copying it into the test directory.

[PATCH 5.13 018/380] selftests/ftrace: Fix requirement check of README file

by Greg Kroah-Hartman

From: Steven Rostedt (VMware) <rostedt(a)goodmis.org> commit 210f9df02611cbe641ced3239122b270fd907d86 upstream. The selftest for ftrace checks some features by checking if the README has text that states the feature is supported by that kernel. Unfortunately, this check gives false positives because it many not be checked if there's spaces in the string to check. This is due to the compare between the required variable with the ":README" string stripped, because neither has quotes around them.

[RFC PATCH v4 0/2] Introduce XSAVE/XRSTOR self-test

by Pengfei Xu

The XSAVE feature set supports the saving and restoring of state components, which is used for process context switching. The state components include x87 state for FPU execution environment, SSE state, AVX state and so on. In order to ensure that XSAVE works correctly, add XSAVE basic test for XSAVE architecture functionality. This patch set tests and verifies the basic functions of XSAVE/XRSTOR in user space; during and after signal processing on the x86 platform, the XSAVE contents of the process should not be changed. This series introduces only the most basic XSAVE tests. In the future, the intention is to continue expanding the scope of these selftests to include more kernel XSAVE-related functionality and XSAVE-managed features like AMX and shadow stacks. ======== - Change from v3 to v4: - Improve the comment in patch 1. - Change from v2 to v3: - Improve the description of patch 2 git log. - Change from v1 to v2: - Improve the cover-letter.

[PATCH] selftests: be sure to make khdr before other targets

by Li Zhijian

LKP/0Day reported some building errors about kvm, and errors message are not always same: - lib/x86_64/processor.c:1083:31: error: ‘KVM_CAP_NESTED_STATE’ undeclared (first use in this function); did you mean ‘KVM_CAP_PIT_STATE2’? - lib/test_util.c:189:30: error: ‘MAP_HUGE_16KB’ undeclared (first use in this function); did you mean ‘MAP_HUGE_16GB’? Although kvm relies on the khdr, they still be built in parallel when -j is specified. In this case, it will cause compiling errors. Here we mark target khdr as NOTPARALLEL to make it be always built first.
