Hello,
kernel test robot noticed a 90.7% regression of stress-ng.tee.ops_per_sec on:
commit: 601dc4addd9d6b950a1fafb99343222e7a2b5070 ("mm: avoid leaving partial pfn mappings around in error case")
https://github.com/bytedance/kernel.git 6.6-velinux
testcase: stress-ng
config: x86_64-bytedance-6.6-velinux
compiler: gcc-12
test machine: 240 threads 1 sockets Genuine Intel(R) 0000 (Granite Rapids) with 192G memory
parameters:
nr_threads: 100%
testtime: 60s
test: tee
cpufreq_governor: performance
