FYI, I like this series, but I held off applying it because I wanted to
verify that the shuffling of the memory regions works on the existing
8996 boards.
Unfortunately it didn't work, either with or without the shuffling on
the db820c - and I've not found the time to figure out why that is. I
hope to get back to this shortly (or that someone else will figure it
out and provide a tested-by)
I gave this a test too on my db820c. Usually the board MSS will crash
after ~0.1 - 0.15 seconds after booting up, then during recovery the
board will crash/reboot somewhere at the end of q6v5_mss_load() (and
typically after successful q6v5_rmb_mba_wait() call.
Occasionally (approximately 1 of 20) the MSS will not crash, presenting
PDS service to the userspace. Even in this state it doesn't seem to be
able to lock the gps location (but this might be related to the big UART
mezzanine sitting on top of the board).
I've had MSS crash on xiaomi-scorpio too, but far less often. It seemed
like some sort of race condition, as it only happened when ADSP and MSS
were booted at the same time. To workaround this, I delayed loading of
the rmtfs service to leave some time between booting ADSP and MSS.
For the tests to get 1:20 I've disabled ADSP (and WiFi/BT) completely.
Without that I think I never got MSS to boot successfully. I think this
is some kind of power/regulators/clock with ADSP and MSS draining too
much power.
Note to myself: check rmtfs/partitions usage on db820c.
Unfortunately there seem to be no SLPI firmware for the db820c, so I can
not test slpi.
A notice regarding the patchset itself. It looks like pil_q6v5_mss.c
driver misses mx and cx proxy power domains for the MSS_MSM8996 case.
I didn't notice that. I guess they stay on and MSS is able to boot
anyway. I'll add them similar to PATCH 2/5.
Thanks!
Regards,
Bjorn
