I see the following remoteproc crash with this patch in on
sm6350/sm7225-fairphone-fp4.
To be clear, all the audio parts for that SoC are not upstream (yet) and
there's still many issues to solve so not sure if it's actually my fault.
Anyways, getting this crash after starting adsp.
[ 97.212943] qcom_q6v5_pas 3000000.remoteproc: fatal error received: ABT_dal.c:287:ABTimeout: AHB Bus hang is detected, Number of bus hang detected := 1 , addr0 = 0x3370000 , addr1 = 0x0!!!
[ 97.212995] remoteproc remoteproc0: crash detected in 3000000.remoteproc: type fatal error
[ 97.213015] remoteproc remoteproc0: handling crash #1 in 3000000.remoteproc
[ 97.213022] remoteproc remoteproc0: recovering 3000000.remoteproc
This happens just after some clocks on the adsp get disabled, this is
from my own debug prints:
[ 97.189097] q6afe_set_lpass_clock: clk_id=780, attri=1, clk_root=0, freq=0
[ 97.189426] q6afe_set_lpass_clock: clk_id=781, attri=1, clk_root=0, freq=0
And then a couple of seconds later the whole phone just crashes into the
900e mode.
Regards
Luca
