drm/amdgpu: fix handling of harvesting for ip_discovery firmware2025-10-13T18:14:15+00:00Alex Deucheralexander.deucher@amd.com2025-09-26T21:31:32+00:00urn:sha1:357d90be2c7aaa526a840cddffd2b8d676fe75a6
Chips which use the IP discovery firmware loaded by the driver
reported incorrect harvesting information in the ip discovery
table in sysfs because the driver only uses the ip discovery
firmware for populating sysfs and not for direct parsing for the
driver itself as such, the fields that are used to print the
harvesting info in sysfs report incorrect data for some IPs. Populate
the relevant fields for this case as well.

We only need the fw based discovery table for sysfs. No
need to parse it. Additionally parsing some of the board
specific tables may result in incorrect data on some boards.
just load the binary and don't parse it on those boards.

With a timeout of only 1 second, my rx 5700XT fails to initialize,
so this increases the timeout to 2s.

drm/amd: Adjust output for discovery error handling2025-06-24T13:58:35+00:00Mario Limonciellomario.limonciello@amd.com2025-06-17T18:30:52+00:00urn:sha1:49f1f9f6c3c9febf8ba93f94a8d9c8d03e1ea0a1
commit 017fbb6690c2 ("drm/amdgpu/discovery: check ip_discovery fw file
available") added support for reading an amdgpu IP discovery bin file
for some specific products. If it's not found then it will fallback to
hardcoded values. However if it's not found there is also a lot of noise
about missing files and errors.
Adjust the error handling to decrease most messages to DEBUG and to show
users less about missing files.

On chips without native IP discovery support, use the fw binary
if available, otherwise we can continue without it.
