drm/format-helper: Pass format-conversion state to helpers Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Javier Martinez Canillas <javierm@redhat.com> # ssd130x Cc: Noralf Trønnes <noralf@tronnes.org> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: David Lechner <david@lechnology.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de

drm/format-helper: Rename test cases to make them more generic The tests available at the moment only check the conversion from XRGB8888 to RGB332. However, more conversions will be tested in the future. In order to make the struct and functions present in the tests more generic, rename xrgb8888_to_rgb332_* to convert_xrgb8888_*.

drm/format-helper: Pass format-conversion state to helpers Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Javier Martinez Canillas <javierm@redhat.com> # ssd130x Cc: Noralf Trønnes <noralf@tronnes.org> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: David Lechner <david@lechnology.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de

drm/format-helper: Pass format-conversion state to helpers Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Javier Martinez Canillas <javierm@redhat.com> # ssd130x Cc: Noralf Trønnes <noralf@tronnes.org> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: David Lechner <david@lechnology.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de

drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_rgb332() Test the conversion from XRGB8888 to RGB332. What is tested? - Different values for the X in XRGB8888 to make sure it is ignored - Different clip values: Single pixel and full and partial buffer - Well known colors: White, black, red, green, blue, magenta, yellow and cyan - Other colors: Randomly picked - Destination pitch How to run the tests? $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/tests \ --kconfig_add CONFIG_VIRTIO_UML=y \ --kconfig_add CONFIG_UML_PCI_OVER_VIRTIO=y Suggested-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: David Gow <davidgow@google.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: José Expósito <jose.exposito89@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220620160640.3790-3-jose.exposito89@gmail.com
