ffcde9e4 - drm: fsl-dcu: enable PIXCLK on LS1021A

Thu, 26 Sep 2024 05:55:51 +0000

drm: fsl-dcu: enable PIXCLK on LS1021AThe PIXCLK needs to be enabled in SCFG before accessing certain DCUregisters, or the access will hang. For simplicity, the PIXCLK is enabledunconditionally, resulting in increased power consumption.Signed-off-by: Matthias Schiffer Signed-off-by: Alexander Stein Fixes: 109eee2f2a18 ("drm/layerscape: Add Freescale DCU DRM driver")Acked-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20240926055552.1632448-2-alexander.stein@ew.tq-group.comSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/drivers/gpu/drm/fsl-dcu/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/fsl-dcu/Kconfig

109eee2f - drm/layerscape: Add Freescale DCU DRM driver

Thu, 20 Aug 2015 02:19:49 +0000

drm/layerscape: Add Freescale DCU DRM driverThis patch add support for Two Dimensional Animation and CompositingEngine (2D-ACE) on the Freescale SoCs.2D-ACE is a Freescale display controller. 2D-ACE describesthe functionality of the module extremely well its name is a valuethat cannot be used as a token in programming languages.Instead the valid token "DCU" is used to tag the register names andfunction names.The Display Controller Unit (DCU) module is a system master thatfetches graphics stored in internal or external memory and displaysthem on a TFT LCD panel. A wide range of panel sizes is supportedand the timing of the interface signals is highly configurable.Graphics are read directly from memory and then blended in real-time,which allows for dynamic content creation with minimal CPUintervention.The features:(1) Full RGB888 output to TFT LCD panel.(2) Blending of each pixel using up to 4 source layersdependenton size of panel.(3) Each graphic layer can be placed with one pixel resolutionin either axis.(4) Each graphic layer support RGB565 and RGB888 direct colorswithout alpha channel and BGRA8888 BGRA4444 ARGB1555 directcolorswith an alpha channel and YUV422 format.(5) Each graphic layer support alpha blending with 8-bitresolution.This is a simplified version, only one primary plane, oneframebuffer, one crtc, one connector and one encoder for TFTLCD panel.Signed-off-by: Alison Wang Signed-off-by: Xiubo Li Signed-off-by: Jianwei Wang Acked-by: Daniel Vetter List of files: /linux-6.15/drivers/gpu/drm/fsl-dcu/Kconfig
