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/pl111/Kconfig

a22f1d80 - drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DAC

drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DACDRM_DUMB_VGA_DAC is a user-visible symbol. Selecting it can cause unmetdirect dependencies such as this (on i386, randconfig): warning: (DRM_PL111) selects DRM_DUMB_VGA_DAC which has unmet direct dependencies (HAS_IOMEM && DRM && DRM_BRIDGE && OF)This is because DRM_DUMB_VGA_DAC depends on OF while DRM_PL111 does not.It does indirectly depend on OF via the ARM and ARM64 dependencies, butsince it can also be enabled under COMPILE_TEST, randconfig can find acase where DRM_PL111 is selected without pulling in OF and not meetingthe dependency for DRM_DUMB_VGA_DAC.Since select is "heavy handed", DRM_DUMB_VGA_DAC is going to be enabledregardless of the above warning and causes the following build error: ../drivers/gpu/drm/bridge/dumb-vga-dac.c: In function 'dumb_vga_probe': ../drivers/gpu/drm/bridge/dumb-vga-dac.c:207:13: error: 'struct drm_bridge' has no member named 'of_node' vga->bridge.of_node = pdev->dev.of_node;See Documentation/kbuild/kconfig-language.txt, "reverse dependencies".Fixes: 49f81d80ab84 ("drm/pl111: Support handling bridge timings")Reported-by: Randy Dunlap Reviewed-by: Eric Anholt Cc: Laurent Pinchart Cc: Archit Taneja Cc: Eric Anholt Signed-off-by: Thierry Reding Signed-off-by: Archit Taneja Link: https://patchwork.freedesktop.org/patch/msgid/20180220102903.27787-1-thierry.reding@gmail.com List of files: /linux-6.15/drivers/gpu/drm/pl111/Kconfig

drm/pl111: Support handling bridge timingsIf the bridge has a too strict setup time for the incomingsignals, we may not be fast enough and then we need tocompensate by outputting the signal on the inverse clockedge so it is for sure stable when the bridge samples it.Since bridges in difference to panels does not expose theirconnectors, make the connector optional in the displaysetup code.Acked-by: Laurent Pinchart Reviewed-by: Eric Anholt Signed-off-by: Linus Walleij Signed-off-by: Archit Taneja Link: https://patchwork.freedesktop.org/patch/msgid/20180112074854.9560-4-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/pl111/Kconfig

drm/pl111: Initial drm/kms driver for pl111This is a modesetting driver for the pl111 CLCD display controllerfound on various ARM platforms such as the Versatile Express. Thedriver has only been tested on the bcm911360_entphn platform so far,with PRIME-based buffer sharing between vc4 and clcd.It reuses the existing devicetree binding, while not using quite asmany of its properties as the fbdev driver does (those are left forfuture work).v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers.v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper).v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work.v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode.v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.Signed-off-by: Tom Cooksey Signed-off-by: Eric Anholt Reviewed-by: Linus Walleij (v5)Acked-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170413031746.12921-2-eric@anholt.net List of files: /linux-6.15/drivers/gpu/drm/pl111/Kconfig
