Greeting,
FYI, we noticed a -54.0% regression of phoronix-test-suite.jxrendermark.RadialGradientPaint.1024x1024.operations_per_second due to commit:
commit: 59dd13ad310793757e34afa489dd6fc8544fc3da ("drm/i915/gem: Flush coherency domains on first set-domain-ioctl")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 12 threads Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 8G memory
with following parameters:
need_x: true
test: jxrendermark-1.2.4
option_a: Radial Gradient Paint
option_b: 1024x1024
cpufreq_governor: performance
ucode: 0xd6
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.

The patch is not expected to have any impact on the machine you are testing on.

What's your code base?
For my side:
1) sync the code to the head of Linux mainline
2) git reset --hard 59dd13ad31
3) git revert 59dd13ad3107
We compare the test result of commit 59dd13ad3107 (step 2) and
2052847b06f8 (step 3, revert 59dd13ad3107), the regression should
related with 59dd13ad3107. Each test case we run 5 times.

Could you share with me your test commands and the hardware info, then I
can reproduce it on my side? Thanks.

It was a i7-8809G, identical i915 behaviour as the i7-8700 the report was
generated on.
sudo Xorg & for i in $(seq 1 120); do ./jx 13 1024 | awk '{print $1}' ; done
using -modesetting + iris (i965 makes no difference, just slightly
slower)
