2023-07-28drm/nouveau/nvkm/dp: Add workaround to fix DP 1.3+ DPCD issuesLyude Paul
Currently we use the drm_dp_dpcd_read_caps() helper in the DRM side of nouveau in order to read the DPCD of a DP connector, which makes sure we do the right thing and also check for extended DPCD caps. However, it turns out we're not currently doing this on the nvkm side since we don't have access to the drm_dp_aux structure there - which means that the DRM side of the driver and the NVKM side can end up with different DPCD capabilities for the same connector. Ideally in order to fix this, we just want to use the drm_dp_read_dpcd_caps() helper in nouveau. That's not currently possible though, and is going to depend on having a bunch of the DP code moved out of nvkm and into the DRM side of things as part of the GSP enablement work. Until then however, let's workaround this problem by porting a copy of drm_dp_read_dpcd_caps() into NVKM - which should fix this issue.

2023-07-28drm/ast: report connection status on Display Port.Jocelyn Falempe
Aspeed always report the display port as "connected", because it doesn't set a .detect_ctx callback. Fix this by providing the proper detect callback for astdp and dp501. This also fixes the following regression: Since commit fae7d186403e ("drm/probe-helper: Default to 640x480 if no EDID on DP") The default resolution is now 640x480 when no monitor is connected. But Aspeed graphics is mostly used in servers, where no monitor is attached. This also affects the remote BMC resolution to 640x480, which is inconvenient, and breaks the anaconda installer. v2: Add .detect callback to the dp/dp501 connector (Jani Nikula) v3: Use .detect_ctx callback, and refactors (Thomas Zimmermann) Add a BMC virtual connector v4: Better indent detect_ctx() functions (Thomas Zimmermann) v5: Enable polling of the dp and dp501 connector status (Thomas Zimmermann) v6: Change check order in ast_astdp_is_connected (Jammy Huang) Fixes: fae7d186403e ("drm/probe-helper: Default to 640x480 if no EDID on DP") Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20230713134316.332502-2-jfalempe@redhat.com

Most aspeed devices have a BMC, which allows to remotely see the screen. Also in the common use case, those servers don't have a display connected. So add a Virtual connector, to reflect that even if no display is connected, the framebuffer can still be seen remotely.
