Hi Dmitry,
I applied all 12 patches you sent (in addition to the GPUPerformance patch), cold boot seems to be working. However, VTNext restart still has a hard crash.
Without the GPUPerformance patch, cold boot seems to work and VTNext restart also seems to work. I've only tested a few cold cycles and restarts of VTNext, but this is what I observe so far.
Thanks, Kim

Hi Dmitry,
Any progress with the cold bootup issue and/or speedup of GPU/CPU?
It took a way longer that we initially expected, but I kept on getting one of occasional issues during startup. With the attached set of patches I do no longer get the coldboot and/or VTNext restart issues. Please consider testing them. The patches are generated against 5.15krn tree.
Paul, can we get an update on hours worked on this for this past month?
Thanks, Kim

Hi Dmitry,
Hope you are well!
1.) Any progress on the cold bootup issue and/or speedup of GPU/CPU?
I was OOO for several days during this week. Still WIP.
2.) I have not seen an email from you in regards to the (un)power patch you were planning on sending to us last week. Again, if it was easy to do, we could test quickly but this is low priority.
I have attached the no-heating,no-power-up patch. Took slightly more time than I expected to rip off the power regulation stuff.
In case the previous message doesn't get through because of the file size, I have uploaded it to the file server. Please find the patch at https://fileserver.linaro.org/s/irYEtnoaAct7pJg
