Subject: [jarkko-tpmdd:tpm1-s3-bug] [random]  5e2bb14a54:
 phoronix-test-suite.ncnn.VulkanGPU.ms 7.0% regression



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.

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.
