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`.

drm/rcar: stop using 'imply' for dependencies The meaning of the 'imply' keyword has changed recently, and neither the old meaning (select the symbol if its dependencies are met) nor the new meaning (enable it by default, but let the user set any other setting) is what we want here. Work around this by adding two more Kconfig options that lead to the correct behavior: if DRM_RCAR_USE_CMM and DRM_RCAR_USE_LVDS are enabled, that portion of the driver becomes usable, and no configuration results in a link error. This avoids a link failure: arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_begin': rcar_du_crtc.c:(.text+0x1444): undefined reference to `rcar_cmm_setup' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_enable': rcar_du_crtc.c:(.text+0x14d4): undefined reference to `rcar_cmm_enable' arm-linux-gnueabi-ld: rcar_du_crtc.c:(.text+0x1548): undefined reference to `rcar_cmm_setup' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_disable': rcar_du_crtc.c:(.text+0x18b8): undefined reference to `rcar_cmm_disable' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_kms.o: in function `rcar_du_modeset_init': Link: https://lore.kernel.org/all/20200417155553.675905-5-arnd@arndb.de/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
