Hello,
kernel test robot noticed a 7.0% regression of phoronix-test-suite.ncnn.VulkanGPU.ms on:
commit: 5e2bb14a5498d7b3197773937cc24fa4ed576836 ("random: Comment out write throttling in add_hwgenerator_randomness()")
git://git.kernel.org/cgit/linux/kernel/git/jarkko/linux-tpmdd.git tpm1-s3-bug
testcase: phoronix-test-suite
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory
parameters:
test: ncnn-1.1.0
option_a: Vulkan GPU
cpufreq_governor: performance
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.

If you fix the issue, kindly add following tag
| Reported-by: kernel test robot <[email protected]>
| Link: https://lore.kernel.org/oe-lkp/[email protected]
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
