2022-12-22drm/todo: update the debugfs clean up taskMaíra Canal
The structs drm_debugfs_info and drm_debugfs_entry introduced a new debugfs structure to DRM, centered on drm_device instead of drm_minor. Therefore, remove the tasks related to create a new device-centered debugfs structure and add a new task to replace the use of drm_debugfs_create_files() for the use of drm_debugfs_add_file() and drm_debugfs_add_files().

2022-11-24drm/connector: Add TV standard propertyMaxime Ripard
The TV mode property has been around for a while now to select and get the current TV mode output on an analog TV connector. Despite that property name being generic, its content isn't and has been driver-specific which makes it hard to build any generic behaviour on top of it, both in kernel and user-space. Let's create a new enum tv norm property, that can contain any of the analog TV standards currently supported by kernel drivers. Each driver can then pass in a bitmask of the modes it supports, and the property creation function will filter out the modes not supported. We'll then be able to phase out the older tv mode property.

With MTL standalone media architecture the wopcm layout has changed, with separate partitioning in WOPCM for the root GT GuC and the media GT GuC. The size of WOPCM is 4MB with the lower 2MB reserved for the media GT and the upper 2MB for the root GT. Given that MTL has GuC deprivilege, the WOPCM registers are pre-locked by the bios.

2022-09-05drm: vkms: Supports to the case where primary plane doesn't match the CRTCIgor Torrente
We will remove the current assumption that the primary plane has the same size and position as CRTC and that the primary plane is the bottom-most in zpos order, or is even enabled. At least as far as the blending machinery is concerned. For that we will add CRTC dimension information to `vkms_crtc_state` and add a opaque black backgound color. Because now we need to fill the background, we had a loss in performance with this change.

2022-09-05drm: vkms: Refactor the plane composer to accept new formatsIgor Torrente
Currently the blend function only accepts XRGB_8888 and ARGB_8888 as a color input. This patch refactors all the functions related to the plane composition to overcome this limitation. The pixels blend is done using the new internal format. And new handlers are being added to convert a specific format to/from this internal format. So the blend operation depends on these handlers to convert to this common format. The blended result, if necessary, is converted to the writeback buffer format. This patch introduces three major differences to the blend function. 1 - All the planes are blended at once. 2 - The blend calculus is done as per line instead of per pixel. 3 - It is responsible to calculates the CRC and writing the writeback buffer(if necessary). These changes allow us to allocate way less memory in the intermediate buffer to compute these operations. Because now we don't need to have the entire intermediate image lines at once, just one line is enough. | Memory consumption (output dimensions) | |:--------------------------------------:| | Current | This patch | |:------------------:|:-----------------:| | Width * Heigth | 2 * Width | Beyond memory, we also have a minor performance benefit from all these changes.

As a result of this variety, sometimes it is hard to identify the correct block that might cause the issue. This commit expands the amdgpu kernel-doc to alleviate this issue by introducing one ASIC table that describes dGPU and another one that shares the APU info.

2022-08-03drm/gem: rename GEM CMA helpers to GEM DMA helpersDanilo Krummrich
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. In order to do this renaming the following script was used: ``` #!/bin/bash DIRS="drivers/gpu include/drm Documentation/gpu" REGEX_SYM_UPPER="[0-9A-Z_\-]" REGEX_SYM_LOWER="[0-9a-z_\-]" REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)" REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)" REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g" REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g" # Find all upper case 'CMA' symbols and replace them with 'DMA'. for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS) do sed -i -E "$REGEX_SED_UPPER" $ff done # Find all lower case 'cma' symbols and replace them with 'dma'. for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS) do sed -i -E "$REGEX_SED_LOWER" $ff done # Replace all occurrences of 'CMA' / 'cma' in comments and # documentation files with 'DMA' / 'dma'. for ff in $(grep -RiHl " cma " $DIRS) do sed -i -E "s/ cma / dma /g" $ff sed -i -E "s/ CMA / DMA /g" $ff done # Rename all 'cma_obj's to 'dma_obj'. for ff in $(grep -RiHl "cma_obj" $DIRS) do sed -i -E "s/cma_obj/dma_obj/g" $ff done ``` Only a few more manual modifications were needed, e.g. reverting the following modifications in some DRM Kconfig files - select CMA if HAVE_DMA_CONTIGUOUS + select DMA if HAVE_DMA_CONTIGUOUS as well as manually picking the occurrences of 'CMA'/'cma' in comments and documentation which relate to "GEM CMA", but not "FB CMA". Also drivers/gpu/drm/Makefile was fixed up manually after renaming drm_gem_cma_helper.c to drm_gem_dma_helper.c.
