Hi Dmitry,
With the latest patch for 5.15, both boards that didn't boot up now boot, but one of the two boards crashes when we run our software. Attached is the dmesg log.
With the latest patch for 5.15, we observe that the CPU functions (Analyze) is a little slower. We also observe that power usage has increased between 4.14 and 5.15: https://docs.google.com/document/d/1UD6FofrJKZ_9W7rGWTkN-DyoVI9KXQxktEXY6eYp...
Thanks, Kim

Hi Dmitry,
This was two weeks ago when I ran this, but I do not think so. Although we didn’t do any temp test in our freezer (room temp only), because we didn’t hear back from you on if this was correct. Should we?
I think you should create a single patch for us to test because the last patch you sent us did not compile, so I’m wondering if the correct patch was sent to us. In that patch, this line didn’t compile: dev_info(gpu: "GPU setting to %ld\n", *freq);
Please give a series of tests to the attached patch. I'm interested in: - speed bins for the boards that crashed when you tested the previous version, check the following line in the dmesg: [ 4.105174] adreno b00000.gpu: Detected speed bin 0
- checking that GPU performance matches the expectations.
- checking that the boards are stable in normal conditions and in the fridge test.
Thank you for your testing!
