Features Supported

Below are the test cases for new features on the Intel GNR platform in OpenEuler (referred to as OE) OS. Please note that the specific test content for each feature can be found in the relevant content under the BM directory, which will not be repeated here. We believe that these test cases are a subset of all related feature tests there.

  • tests-avx512vbmi
  • tests-cet
  • tests-cstate
  • tests-edac
  • tests-iax
  • tests-ifs
  • tests-isst
  • tests-rapl
  • tests-sdsi
  • tests-topology
  • tests-tpmi
  • tests-ufs
  • tests-umip
  • tests-xsave

Tested with OpenEuler 24.03 LTS

Dependencies

tests-topology

  • hwloc.x86_64 package
yum install hwloc
  • cpuid tool

tests-sdsi

  • intel_sdsi tool Build and install from the kernel source code: tools/arch/x86/intel_sdsi/intel_sdsi.c

tests-isst

  • intel-speed-select stress-ng.x86_64
yum install stress-ng
ln -s /usr/bin/stress-ng /usr/bin/stress

tests-cstate

  • perf.x86_64 package
yum install perf

tests-pstate and tests-rapl

  • turbostat tool version 2024.xx.xx is required, recompile from the latest mainline kernel source code: tools/power/x86/turbostat/turbostat.c

Known Issues

Tools Missing

  • cpuid (workaround: copy from CentOS 9)

  • rdmsr-tool

  • Kernel Features Missing gcc missing AMX FP16 support (workaround: compile tmul.c with gcc13+ and copy the binary into OE)

  • Kernel idxd driver missing SVA support (resulting in DSA/IAX not working)

  • CET OE kernel does NOT configuure CONFIG_X86_USER_SHADOW_STACK=y, resulting in CET SHSTK not working.

  • OS failed to put CPUs offline, the unknown driver module may have improper IRQ allocation, which will cause available IRQ is not enough during CPUs Offline and online. e.g. error log CPU 206 has 151 vectors, 103 available. Cannot disable CPU CPU 207 has 150 vectors, 102 available. Cannot disable CPU
