Subject: [ardb:x86-pie-v3+i386] [x86] c25feb76bc:
stress-ng.getrandom.ops_per_sec 19.2% regression
Hello,
kernel test robot noticed a 19.2% regression of stress-ng.getrandom.ops_per_sec on:
commit: c25feb76bcb9eef1db49b4793195808b5b268bdd ("x86: Use PIE codegen for the relocatable 64-bit kernel")
https://git.kernel.org/cgit/linux/kernel/git/ardb/linux.git x86-pie-v3+i386
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 256 threads 2 sockets Intel(R) Xeon(R) 6768P CPU @ 2.4GHz (Granite Rapids) with 64G memory
parameters:
nr_threads: 100%
testtime: 60s
test: getrandom
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.shm-sysv.ops_per_sec 7.0% regression |
| test machine | 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=shm-sysv |
| | testtime=60s |
+------------------+---------------------------------------------------------------------------------------------+
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
