Subject: [drm/i915] 58586680ff:
phoronix-test-suite.darktable.Boat.OpenCL.seconds 139.5% regression
Greeting,
FYI, we noticed a 139.5% regression of phoronix-test-suite.darktable.Boat.OpenCL.seconds due to commit:
commit: 58586680ffadc37636120d9f59955aa5f7a32b7d ("drm/i915: Disable atomics in L3 for gen9")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 12 threads 1 sockets Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 16G memory
with following parameters:
test: darktable-1.0.5
option_a: Boat
option_b: OpenCL
cpufreq_governor: performance
ucode: 0xec
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.
