[BUG] check-kmod-load-unload fails on MTL

[plbossart]

TPLG=/lib/firmware/intel/sof-ace-tplg/sof-hda-generic-4ch.tplg MODEL=MTLP_RVP_HDA ~/sof-test/test-case/check-kmod-load-unload.sh
Polling 'sof_firmware_boot_complete --since=@1684343454' every 1s for 10s
Command 'sof_firmware_boot_complete --since=@1684343454' timed out after 10s and 11 attempts
2023-05-17 17:11:08 UTC [INFO] Test Result: FAIL!

However running the kmod scripts works fine.

It's likely a timeout value that's not long enough for MTL. Can we increase it to 70s as done for the boot?

@fredoh9 @marc-hb @keqiaozhang this is a gap in our coverage, we do need to start testing module load/unload - possibly with a reduced number of cycles since we lose one minute with the i915 issue

This is not a sof-test bug, this is new, platform-specific timeout feature (not questioning the priority)

This i915 timeout/bug has been a royal pain all across the board, @kv2019i is there really no way to avoid it?

[plbossart]

we already have a 70s timeout in other parts of sof-test, so I will assert that it's a bug. This should just work with the delay being handled.

We have the same issue for all FPGA tests btw, the tests need to deal with the i915 60s wait.

[plbossart]

case-lib/config.sh:MAX_WAIT_FW_LOADING=${MAX_WAIT_FW_LOADING:-70}

# Set MAX Polling time to check FW Loading. If FW is already loaded, it will
# return immediately. Default value is set to 60 seconds, because i915 driver
# timeout is 60 seconds.
MAX_WAIT_FW_LOADING=${MAX_WAIT_FW_LOADING:-70}

why can't we use this for kmod tests as well?

[marc-hb]

Re-opening because this is not in any test plan yet, will close once this is running daily.

EDIT: blocked by bug 4442 below.

There's an open bug for MTL when testing kmod
