Re: [PATCH] drm/fourcc: add LINEAR modifiers with an exact pitch alignment

*(#$ u64 next to the u32. Yeah probably. Otoh I know inertia, so I am tempted to go with the oddball LINEAR_VEDNOR_A_VENDOR_B_INTEROP thing and stretch the runway for a bit. And we just assign those as we go as a very special thing, and the drivers that support it would prefer it above just LINEAR if there's no other common format left. Also makes it really obvious what all userspace/kernel driver enabling would be needed to justify such a modifier. -Sima > > Cheers, > Daniel -- Simona Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch -- -- Thomas Zimmermann Graphics Driver Developer SUSE Software Solutions Germany GmbH Frankenstrasse 146, 90461 Nuernberg, Germany GF: Ivo Totev, Andrew Myers, Andrew McDonald, Boudien Moerman HRB 36809 (AG Nuernberg)

e also has alignment requirements for framebuffer width (usually 8 pixels). Best regards Thomas [1] https://elixir.bootlin.com/linux/v6.12.6/source/drivers/gpu/drm/renesas/rcar-du/rcar_du_kms.c#L410 -- -- Thomas Zimmermann Graphics Driver Developer SUSE Software Solutions Germany GmbH Frank
