Subject: [PATCH v3 0/2] Fixes for omapdrm console
Date: Wed, 28 Feb 2024 08:35:30 +0200	[thread overview]
Message-ID: <20240228063540.4444-1-tony@atomide.com> (raw)

Here are two fixes for omapdrm for missing drm_framebuffer_funcs.dirty
that needs to be paired with omap_framebuffer_dirty(), and to add
FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS so things behave as earlier with
drm_fb_helper_sys_write(). Without these fixes, the console won't update
for the command mode displays. And likely mmap() using writes can miss
updates as noted by Thomas.

Regards,

Tony

Changes since v2:
- Fix cache issue noted by Tomi using custom omap_fbdev_fb_mmap() as
  suggested by Thomas

- Add FB_DMAMEM_HELPERS_DEFERRED Kconfig option and use it for omapdrm
  as noted by Thomas

Changes since v1:

- Add FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS to use with
  FB_DEFAULT_DEFERRED_OPS as suggested by Thomas
