drm/tidss: Use GEM DMA fbdev emulation

2023-03-14T16:07:49+00:00

Use the fbdev emulation that is optimized for DMA helpers. Avoids possible shadow buffering and makes the code simpler. Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230313155138.20584-18-tzimmermann@suse.de

drm/tidss: Implement struct drm_plane_helper_funcs.atomic_enable

2023-02-20T14:20:45+00:00

Enable the primary plane for tidss hardware via atomic_enable. Atomic helpers invoke this callback only when the plane becomes active.

drm/tidss: Remove unnecessary include statements for drm_crtc_helper.h

2023-01-18T08:25:32+00:00

Several source files include drm_crtc_helper.h without needing it or only to get its transitive include statements; leading to unnecessary compile-time dependencies. Directly include required headers and drop drm_crtc_helper.h where possible.

drm: tidss: Fix pixel format definition

2022-12-16T17:24:39+00:00

There was a long-standing bug from a typo that created 2 ARGB1555 and ABGR1555 pixel format entries. Weston 10 has a sanity check that alerted me to this issue. According to the Supported Pixel Data formats table we have the later entries should have been for Alpha-X instead.

drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}

2022-08-03T16:32:27+00:00

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 Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Signed-off-by: Danilo Krummrich Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-5-dakr@redhat.com
