Thomas Zimmermann 38b2d9d385 drm/format-helper: Cache buffers with struct drm_format_conv_state ... Hold temporary memory for format conversion in an instance of struct drm_format_conv_state. Update internal helpers of DRM's format-conversion code accordingly. Drivers will later be able to maintain this cache by themselves. Besides caching, struct drm_format_conv_state will be useful to hold additional information for format conversion, such as palette data or foreground/background colors. This will enable conversion from indexed color formats to component-based formats. v5: * improve documentation (Javier, Noralf) v3: * rename struct drm_xfrm_buf to struct drm_format_conv_state (Javier) * remove managed cleanup * add drm_format_conv_state_copy() for shadow-plane support Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Acked-by: Noralf Trønnes <noralf@tronnes.org> Tested-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-2-tzimmermann@suse.de		2023-11-14 10:01:12 +01:00
