Hi all, On the past, I have tested vsp source on rcar gen2 koelsch board, using the patches series below(Apart from the below patch series, I have enabled "CONFIG_DRM_RCAR_VSP=y") https://git.linuxtv.org/pinchartl/media.git/log/?h=drm/du/panels 1) [HACK] ARM: shmobile: r8a7791: Link the VSP1 and DU 2) [HACK] v4l: vsp1: Disable UAPI for VSP1D 3) [HACK] drm: rcar-du: Enable VSP source support for R8A7791 But on the latest renesas-dev branch looks like it is broken The issue is kernel doesn't boot, if I connect display panel. Looks like it is hanging in register_framebuffer. [ 5.344412] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [ 5.364250] [drm] No driver support for vblank timestamp query. Have any one noticed this issue? Regards, Biju Renesas Electronics Europe Ltd, Dukes Meadow, Millboard Road, Bourne End, Buckinghamshire, SL8 5FH, UK.
