[RFC PATCH 04/17] drm/vkms: Allow to configure multiple CRTCs
José Expósito
jose.exposito89 at gmail.com
Tue Aug 13 10:44:15 UTC 2024
Add a list of CRTC configurations to vkms_config and add as many CRTCs
as configured during output initialization.
For backwards compatibility, create a single CRTC in the default
configuration.
Since writeback support, vblank and composer states are now per CRTC,
extract all the fields to the vkms_crtc structure and allow each
vkms_device to have a list of CRTCs.
