drm: xlnx: DRM/KMS driver for Xilinx ZynqMP DisplayPort Subsystem The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort Subsystem. It includes a buffer manager, a video pipeline renderer (blender), an audio mixer and a DisplayPort source controller (transmitter). The DMA engine the provide data to the buffer manager, as well as the DisplayPort PHYs that drive the lanes, are external to the subsystem and interfaced using the DMA engine and PHY APIs respectively. This driver supports the DisplayPort Subsystem and implements - Two planes, for graphics and video - One CRTC that supports alpha blending - One encoder for the DisplayPort transmitter - One connector for an external monitor It currently doesn't support - Color keying - Test pattern generation - Audio - Live input from the Programmable Logic (FPGA) - Output to the Programmable Logic (FPGA) Signed-off-by: Hyun Kwon <hyun.kwon@xilinx.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

drm/display: Introduce a DRM display-helper module Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain helpers for other video-output standards, such as HDMI. Drivers will have to select their required video-output helpers. Linking all display-related code into a single module avoids the proliferation of small kernel modules. The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz, and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace to drm_display_helper. v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/ Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-4-tzimmermann@suse.de

drm/gem: rename GEM CMA helpers to GEM DMA helpers 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. This patch is compile-time tested building a x86_64 kernel with `make allyesconfig && make drivers/gpu/drm`.

subsystem.
drm: xlnx: zynqmp_dpsub: Add DP audio support Add basic DisplayPort audio support. Support non-live audio playback from two PCMs (DMA channels), and the volume control in the audio mixer. As older dtb files may not have the audio DMA channels defined, the driver will just mark the audio support as disabled if the audio DMA is missing, and will continue with only display support. Note: Reset doesn't seem to work (ZYNQMP_DISP_AUD_SOFT_RESET). If we do a reset, audio playback won't start again even if, afaics, we do set up all the necessary registers. So, at the moment, resetting the audio block in dp_dai_hw_free() is commented out.
