drm/meson: Run DRM default client setupCall drm_client_setup() to run the kernel's default client setupfor DRM. Set fbdev_probe in struct drm_driver, so that the clientsetup can start the common fbdev client.The meson driver specifies a preferred color mode of 32.

8f7f1155 - Revert "drm: Make drivers depends on DRM_DW_HDMI"

Mon, 22 Apr 2024 10:30:38 +0000

Revert "drm: Make drivers depends on DRM_DW_HDMI"This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helpercode should always be selected by the driver that needs it, for theconvenience of the final user configuring a kernel.The user who configures a kernel should not need to know which helpersare needed for the driver he is interested in. Making a driver dependon helper code means that the user needs to know which helpers to enablefirst, which is very user-unfriendly.Signed-off-by: Geert Uytterhoeven Acked-by: Arnd Bergmann Link: https://patchwork.freedesktop.org/patch/msgid/bd93d43b07f8ed6368119f4a5ddac2ee80debe53.1713780345.git.geert+renesas@glider.beSigned-off-by: Maxime Ripard List of files: /linux-6.15/drivers/gpu/drm/meson/Kconfig

drm/meson: add support for MIPI-DSI transceiverThe Amlogic G12A/G12B/SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver(ver 1.21a), with a custom glue managing the IP resets, clock and datainputs similar to the DW-HDMI Glue on other Amlogic SoCs.This adds support for the Glue managing the transceiver, mimicing the initflow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver,the digital D-PHY and the Analog PHY in the proper way.An optional "MEAS" clock can be enabled to measure the delay between eachvsync feeding the DW-MIPI-DSI transceiver.Signed-off-by: Neil Armstrong Reviewed-by: Jagan Teki Reviewed-by: Nicolas Belin Tested-by: Nicolas Belin # on Khadas VIM3 + TS050 PanelSigned-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20230512-amlogic-v6-4-upstream-dsi-ccf-vim3-v5-12-56eb7a4d5b8e@linaro.org List of files: /linux-6.15/drivers/gpu/drm/meson/Kconfig

4a83c26a - drm/gem: rename GEM CMA helpers to GEM DMA helpers

Tue, 02 Aug 2022 00:04:03 +0000

drm/gem: rename GEM CMA helpers to GEM DMA helpersRename "GEM CMA" helpers to "GEM DMA" helpers - considering thehierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEMDMA" 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 beconfused 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 thefollowing modifications in some DRM Kconfig files - select CMA if HAVE_DMA_CONTIGUOUS + select DMA if HAVE_DMA_CONTIGUOUSas well as manually picking the occurrences of 'CMA'/'cma' in comments anddocumentation which relate to "GEM CMA", but not "FB CMA".Also drivers/gpu/drm/Makefile was fixed up manually after renamingdrm_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`.Acked-by: Sam Ravnborg Acked-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Signed-off-by: Danilo Krummrich Reviewed-by: Liviu Dudau #drivers/gpu/drm/armSigned-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-4-dakr@redhat.com List of files: /linux-6.15/drivers/gpu/drm/meson/Kconfig
