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/tilcdc/Kconfig

92b6f89f - drm: Add separate Kconfig option for fbdev helpers

Tue, 08 Oct 2013 15:44:47 +0000

drm: Add separate Kconfig option for fbdev helpersFor drivers which might want to disable fbdev legacy support.Select the new option in all drivers for now, so this shouldn't resultin any change. Drivers need some work anyway to make fbdev supportoptional (if they have it implemented, that is), so the recommendedway to expose this is by adding per-driver options. At least as longas most drivers don't support disabling the fbdev support.v2: Update for new drm drivers msm and rcar-du. Note that Rob's msmdriver can already take advantage of this, which allows us to buildmsm without any fbdev depencies in the kernel!v3: Move the MODULE_* stuff from the fbdev helper file todrm_crtc_helper.c.Cc: David Herrmann Cc: Rob Clark Reviewed-by: Rob Clark Acked-by: Dave Airlie Reviewed-by: Chon Ming Lee Signed-off-by: Daniel Vetter List of files: /linux-6.15/drivers/gpu/drm/tilcdc/Kconfig

a38884f6 - videomode: simplify videomode Kconfig and Makefile

Tue, 12 Mar 2013 08:15:43 +0000

videomode: simplify videomode Kconfig and MakefileThis patch simplifies videomode related Kconfig and Makefile. After thispatch, there's only one non-user selectable Kconfig option left,VIDEOMODE_HELPERS. The reasons for the change:* Videomode helper functions are not something that should be shown in the kernel configuration options. The related code should just be included if it's needed, i.e. selected by drivers using videomode.* There's no need to have separate Kconfig options for videomode and display_timing. First of all, the amount of code for both is quite small. Second, videomode depends on display_timing, and display_timing in itself is not really useful, so both would be included in any case.* CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS describes better what's included.Signed-off-by: Tomi Valkeinen Cc: Steffen Trumtrar Acked-by: Laurent Pinchart List of files: /linux-6.15/drivers/gpu/drm/tilcdc/Kconfig

drm/tilcdc: add TI LCD Controller DRM driver (v4)A simple DRM/KMS driver for the TI LCD Controller found in varioussmaller TI parts (AM33xx, OMAPL138, etc). This driver uses theCMA helpers. Currently only the TFP410 DVI encoder is supported(tested with beaglebone + DVI cape). There are also various LCDdisplays, for which support can be added (as I get hw to test on),and an external i2c HDMI encoder found on some boards.The display controller supports a single CRTC. And the encoder+connector are split out into sub-devices. Depending on which LCDor external encoder is actually present, the appropriate outputmodule(s) will be loaded.v1: originalv2: fix fb refcnting and few other cleanupsv3: get +/- vsync/hsync from timings rather than panel-info, add option DT max-bandwidth field so driver doesn't attempt to pick a display mode with too high memory bandwidth, and other small cleanupsv4: remove some unneeded stuff from panel-info struct, properly set high bits for hfp/hsw/hbp for rev 2, add DT bindings docsSigned-off-by: Rob Clark Reviewed-by: Daniel Vetter Tested-by: Koen Kooi List of files: /linux-6.15/drivers/gpu/drm/tilcdc/Kconfig
