Update XRGB8888-to-XRGB2101010 conversion to support struct iosys_map and convert all users. Although these are single-plane color formats, the new interface supports multi-plane formats for consistency with drm_fb_blit(). v2: * update documentation (Sam) * add TODO on vaddr location (Sam) Signed-off-by:

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:

Inline the helpers for initializing the hardware FB, the memory management and the modesetting into the device-creation function. No functional changes. In the original code, init helpers depended on values from other init helpers. Inlining the functions ensures that steps are taken in the correct order. It's also easier to see what happens. The device is simple enough to be set up in one function. Only clocks and regulators are still set up in their own helpers, as their presence is system dependent. Signed-off-by:

There's no point in explicitly trying to align virtual memory to facilitate huge page table entries or huge page memory in buffer objects given that they're not being used. Transparent hugepages support for vram allocations has been gradually retired over the last two years making alignment of unmapped areas unneeded and pointless. Signed-off-by:

The vmw_user_bo_noref_lookup() function cannot return NULL. If it could, then this function would return PTR_ERR(NULL) which is success. Returning success without initializing "*vmw_bo_p = vmw_bo;" would lead to an uninitialized variable bug in the caller. Smatch complains about this: drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c:1177 vmw_translate_mob_ptr() warn: passing zero to 'PTR_ERR' drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c:1314 vmw_cmd_dx_bind_query() error: uninitialized symbol 'vmw_bo'.

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: -

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 e57924d4 ("drm/doc: Task to rename CMA helpers") requests to rename the CMA helpers and implies that people seem to be confused about the naming.

Move the PIXPLLC code into per-model source files and wire it up with per-model callbacks. No functional changes. The PIXPLLC pixel-clock is part of the CRTC, but really separate hardware that varies with each model of the G200. Move the PIXPLLC code for each model into the per-model source file and call it from CRTC helpers via device functions. This allows to remove struct mgag200_pll and the related code.

Drop simple-KMS in favor of regular atomic helpers. Makes the code more modular and hence better to adapt to per-model requirements. The simple-KMS helpers provide few extra features, so the patch is mostly about open-coding what simple-KMS does. The simple-KMS helpers do mix up plane and CRTC state. Changing to regular atomic helpers requires to split some of the simple-pipe functions into per-plane and per-CRTC code No functional changes. v3: * always run drm_atomic_helper_check_plane_state() * clean up style Signed-off-by:

Store the primary plane's color format in the CRTC state and use it for programming the CRTC's gamma LUTs. Gamma tables (i.e., color management) are provided by the CRTC, but depend in the primary plane's color format. Store the format in the CRTC state and use it. This has not been an issue with simple-KMS helpers, which mix-up plane and CRTC state to some extent. For using regular atomic helpers, it's necessary to distinguish between the two. Signed-off-by:
