Hi Dmitry,
For item 1 below, should this fix the " gpu fault ring " error we were still seeing a couple of weeks ago (1/23/2023)? : [ 156.660355] msm 900000.mdss: CP | opcode error | possible opcode=0x00000000 [ 156.662139] msm 900000.mdss: [drm:a5xx_irq] *ERROR* gpu fault ring 0 fence 5e47 status 800001C1 rb 1820/17e6 ib1 0000000003C1B000/0000 ib2 0000000001483000/0000 [
Should we run our temp test to see if we still see this error with your latest changes from '1'? I'm just trying to understand what item '1' is.
It was an interim update. At this moment I have narrowed down and fixed the issue that prevented the GPU to go to higher frequencies under the load. Please let me run more tests on my side, then I will push the updates to the branch and afterwards I will ping you for the temp chamber and, more importantly, GPU load/fps tests.
Thanks, Kim

Hello,
A set of updates from our side.
- We have started the process of migrating our repositories to new service. Please consider migrating the repository url on your side from git.linaro.org to https://git.codelinaro.org/linaro/qcomlt/kernel/ .
The branch name states intact (release/db820c/qcomlt-5.15) The old repository location will mirror the new location, but it might take some time for the changes to propagate to it.
I have pushed a set of patches fixing two issues I narrowed down during my tests of the GPU. I will continue working on the driver.
Regarding fixing the GPU clocks. Please consider applying the attached patch, which should fix the minimum clock rate to 510 MHz.
If I interpret your last test results correctly, the issue really is in the GPU rate handling, so this patch should provide a workaround.
-- With best wishes Dmitry
