2022-08-10drm/format-helper: Rework XRGB8888-to-RGBG565 conversionThomas Zimmermann1-6/+3
Update XRGB8888-to-RGB565 conversion to support struct iosys_map and convert all users.

2022-08-10drm/format-helper: Provide drm_fb_blit()Thomas Zimmermann1-3/+4
Provide drm_fb_blit() that works with struct iosys_map. Update all users of drm_fb_blit_toio(), which required a destination buffer in I/O memory. This patch only updates the function's interface. The implementation still relies on the destination buffer to be located in I/O memory. See the follow-up patches for implementational changes. The new function's interface works with multi-plane color formats, but again implementation only supports a single plane for now. v2: * rebase onto refactored simpledrm * use IOSYS_MAP_INIT_VADDR() (Sam) * update the commit message on the use of I/O memory (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220808125406.20752-3-tzimmermann@suse.de

2022-08-03drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}Danilo Krummrich1-2/+2
The field paddr of struct drm_gem_dma_object holds a DMA address, which might actually be a physical address. However, depending on the platform, it can also be a bus address or a virtual address managed by an IOMMU. Hence, rename the field to dma_addr, which is more applicable. In order to do this renaming the following coccinelle script was used: ``` @@ struct drm_gem_dma_object *gem; @@ - gem->paddr + gem->dma_addr @@ struct drm_gem_dma_object gem; @@ - gem.paddr + gem.dma_addr @exists@ typedef dma_addr_t; symbol paddr; @@ dma_addr_t paddr; <... - paddr + dma_addr ...> @@ symbol paddr; @@ dma_addr_t - paddr + dma_addr ; ``` This patch is compile-time tested with: ``` make ARCH={x86_64,arm,arm64} allyesconfig make ARCH={x86_64,arm,arm64} drivers/gpu/drm` ``` Acked-by: Sam Ravnborg <sam@ravnborg.org> Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Danilo Krummrich <dakr@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-5-dakr@redhat.com
2022-08-03drm/gem: rename GEM CMA helpers to GEM DMA helpersDanilo Krummrich3-80/+80
Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM DMA" seems to be more applicable. Besides that, commit e57924d4ae80 ("drm/doc: Task to rename CMA helpers") requests to rename the CMA helpers and implies that people seem to be confused about the naming.

Add functions drm_edid_override_set() and drm_edid_override_reset() to support "edid_override" connector debugfs, and to hide the details about it in drm_edid.c. No functional changes at this time. Also note in the connector.override_edid flag kernel-doc that this is only supposed to be modified by the code doing debugfs EDID override handling. Currently, it is still being modified by amdgpu in create_eml_sink() and handle_edid_mgmt() for reasons unknown. This was added in commit 4562236b3bc0 ("drm/amd/dc: Add dc display driver (v2)") and later moved to amdgpu_dm.c in commit e7b07ceef2a6 ("drm/amd/display: Merge amdgpu_dm_types and amdgpu_dm").

2022-06-21drm: Config orientation property if panel provides itHsin-Yi Wang1-0/+14
Panel orientation property should be set before drm_dev_register(). Some drm driver calls drm_dev_register() in .bind(). However, most panels sets orientation property relatively late, mostly in .get_modes() callback, since this is when they are able to get the connector and binds the orientation property to it, though the value should be known when the panel is probed. In drm_bridge_connector_init(), if a bridge is a panel bridge, use it to set the connector's panel orientation property.
