Subject: [io_uring] 584b0180f0:
phoronix-test-suite.fio.SequentialWrite.IO_uring.Yes.Yes.1MB.DefaultTestDirectory.mb_s
-10.2% regression
Greeting,
FYI, we noticed a -10.2% regression of phoronix-test-suite.fio.SequentialWrite.IO_uring.Yes.Yes.1MB.DefaultTestDirectory.mb_s due to commit:
commit: 584b0180f0f4d67d7145950fe68c625f06c88b10 ("io_uring: move read/write file prep state into actual opcode handler")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
test: fio-1.14.1
option_a: Sequential Write
option_b: IO_uring
option_c: Yes
option_d: Yes
option_e: 1MB
option_f: Default Test Directory
cpufreq_governor: performance
ucode: 0x500320a
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.
test-url: http://www.phoronix-test-suite.com/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
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.
