8545a6f5 - drm/mcde: Run DRM default client setup

Tue, 24 Sep 2024 07:12:23 +0000

drm/mcde: 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 mcde driver specifies a preferred color mode of 32. As thisis the default if no format has been given, leave it out entirely.v5:- select DRM_CLIENT_SELECTIONSigned-off-by: Thomas Zimmermann Cc: Linus Walleij Acked-by: Linus Walleij Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-26-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/mcde/Kconfig

c95d67a6 - drm: Clean-up superfluously selecting VT_HW_CONSOLE_BINDING

Mon, 08 Jan 2024 12:17:57 +0000

drm: Clean-up superfluously selecting VT_HW_CONSOLE_BINDINGAs config FRAMEBUFFER_CONSOLE already selects VT_HW_CONSOLE_BINDING, thereis no need for any drm driver to repeat that rule for selecting.Remove those duplications of selecting VT_HW_CONSOLE_BINDING.Signed-off-by: Lukas Bulwahn [sima: Note that this is only correct since a5ae331edb02 ("drm: Dropselect FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION") because select inKconfig isn't recursive and so needs to be replicated.]Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20240108121757.14069-1-lukas.bulwahn@gmail.com List of files: /linux-6.15/drivers/gpu/drm/mcde/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/mcde/Kconfig

09717af7 - drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

drm: Remove CONFIG_DRM_KMS_CMA_HELPER optionLink drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPERhas been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. SelectingKMS helpers and CMA will now automatically enable CMA KMS helpers.Some drivers' Kconfig files did not correctly select KMS or CMA helpers.Fix this as part of the change.Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20211106193509.17472-3-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/mcde/Kconfig

d795fd32 - drm/mcde: Support DPI output

Thu, 12 Nov 2020 14:29:25 +0000

drm/mcde: Support DPI outputThis implements support for DPI output using the port nodein the device tree to connect a DPI LCD display to theMCDE. The block also supports TV-out but we leave thatfor another day when we have a hardware using it.We implement parsing and handling of the "port" node,and follow that to the DPI endpoint.The clock divider used by the MCDE to divide down the"lcdclk" (this has been designed for TV-like frequencies)is represented by an ordinary clock provider internallyin the MCDE. This idea was inspired by the PL111 solutionby Eric Anholt: the divider also works very similar tothe Pl111 clock divider.We take care to clear up some errors regarding the numberof available formatters and their type. We have 6 DSIformatters and 2 DPI formatters.Tested on the Samsung GT-I9070 Janice mobile phone.Signed-off-by: Linus Walleij Acked-by: Sam Ravnborg Cc: Stephan Gerhold Cc: phone-devel@vger.kernel.orgCc: upstreaming@lists.sr.htLink: https://patchwork.freedesktop.org/patch/msgid/20201112142925.2571179-2-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/mcde/Kconfig

5fc537bf - drm/mcde: Add new driver for ST-Ericsson MCDE

Fri, 24 May 2019 09:20:19 +0000

drm/mcde: Add new driver for ST-Ericsson MCDEThis adds a new DRM driver for the ST-Ericsson Multi ChannelDisplay Engine, MCDE display controller.This hardware has three independent DSI hosts and can compositand display several memory buffers onto an LCD display. Itwas developed for several years inside of ST-Ericsson andshipped with a few million mobile phones from Sony and Samsung,as well as with the Snowball community development board.The driver is currently pretty rudimentary but supports asimple framebuffer so we can get penguins and graphics whenusing these SoCs.Acked-by: Daniel Vetter Signed-off-by: Linus Walleij Link: https://patchwork.freedesktop.org/patch/msgid/20190524092019.19355-1-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/mcde/Kconfig
