This patch series is for making the GPD Win Max display usable with Linux.
The GPD Win Max is a small laptop, and its eDP panel does not send an EDID over DPCD; the EDID is instead available in the intel opregion, in mailbox #5 [1]
The first patch is based on Jani's patch series [2] adding support for the opregion, with changes. I've changed authorship, but I'd be glad to revert it
If you don't mind, please just add:
Co-developed-by: Jani Nikula jani.nikula@intel.com
Thanks, Jani.
The second patch is just to fix the orientation of the panel.
Changes since v1:
- rebased on drm-tip
- squashed patch 1 & 2
- picked up Reviewed-by from Hans de Goede (thanks for the review)
Changes since v2:
- rebased on drm-tip
- updated commit message
When v2 was initially sent [3] Ville Syrjälä suggested that it might be a good idea to use the ACPI _DDC method instead to get the EDID, to cover a wider range of hardware. Unfortunately, it doesn't seem available on GPD Win Max, so I think this work should be done independently, and this patch series considered separately.
