https://git.shady.money/linux/atom?h=v5.02018-08-27T20:20:17Zdrm/amd/display: Add support for hw_state logging via debugfs2018-08-27T20:20:17ZNicholas Kazlauskasnicholas.kazlauskas@amd.com2018-08-14T19:40:57Zurn:sha1:e498eb7136042aa9a352b1039c678537f4694158
[Why]
We have logging methods for printing hardware state for newer ASICs
but no way to trigger the log output.
[How]
Add support for triggering the output via writing to a debugfs file
entry. Log output currently goes into dmesg for convenience, but
accessing via a read should be possible later.

drm/amd/display: Add front end for dp debugfs files2018-07-05T21:38:38ZDavid FrancisDavid.Francis@amd.com2018-06-01T13:49:06Zurn:sha1:dc38fd9dac3e15538c7c238c4dfb98ceb408fa19
As part of hardware certification, read-write access to
the link rate, lane count, voltage swing, pre-emphasis,
and PHY test pattern of DP connectors is required. This commit
adds debugfs files that will correspond to these values.
The file operations are not yet implemented: currently
writing or reading them does nothing.
