drm/gem: rename GEM CMA helpers to GEM DMA helpers

2022-08-03T16:31:49Z

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`.

The DP-helper module has been replaced by the display-helper module. So the driver have to select it.

drm/rockchip: Add VOP2 driver

2022-05-04T12:05:47Z

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568. It replaces the VOP unit found in the older Rockchip SoCs. This driver has been derived from the downstream Rockchip Kernel and heavily modified: - All nonstandard DRM properties have been removed - dropped struct vop2_plane_state and pass around less data between functions - Dropped all DRM_FORMAT_* not known on upstream - rework register access to get rid of excessively used macros - Drop all waiting for framesyncs The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB board. Overlay support is tested with the modetest utility. AFBC support on the cluster windows is tested with weston-simple-dmabuf-egl on weston using the (yet to be upstreamed) panfrost driver support.

drm/rockchip: Make VOP driver optional

2022-05-04T12:05:47Z

With upcoming VOP2 support VOP won't be the only choice anymore, so make the VOP driver optional. This also adds a dependency from ROCKCHIP_ANALOGIX_DP to ROCKCHIP_VOP, because that driver currently only links and works with the VOP driver.

drm/display: Introduce a DRM display-helper module

2022-04-25T09:19:21Z

Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain helpers for other video-output standards, such as HDMI. Drivers will have to select their required video-output helpers. Linking all display-related code into a single module avoids the proliferation of small kernel modules. The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz, and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace to drm_display_helper. v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/ Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-4-tzimmermann@suse.de

drm/dp: Move DisplayPort helpers into separate helper module

2022-01-17T10:25:44Z

Move DisplayPort functions into a separate module to reduce the size of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c This change can help to reduce the size of the kernel binary. Some numbers from a x86-64 test build: Before: drm_kms_helper.ko: 447480 bytes After: drm_dp_helper.ko: 216632 bytes drm_kms_helper.ko: 239424 bytes For early-boot graphics, generic DRM drivers, such as simpledrm, require DRM KMS helpers to be built into the kernel. Generic helper functions for DisplayPort take up a significant portion of DRM KMS helper library. These functions are not used by generic drivers and can be loaded as a module. v3: * fix include statement in DRM selftests v2: * move DP helper code into dp/ (Jani) Signed-off-by: Thomas Zimmermann Acked-by: Lyude Paul Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220114114535.29157-4-tzimmermann@suse.de

drm/rockchip: dsi: add ability to work as a phy instead of full dsi

2021-07-25T15:19:49Z

SoCs like the rk3288 and rk3399 have 3 mipi dphys on them. One is TX- only, one is RX-only and one can be configured to do either TX or RX. The RX phy is statically connected to the first Image Signal Processor, the TX phy is statically connected to the first DSI controller and the TXRX phy is connected to both the second DSI controller as well as the second ISP. The RX dphy is controlled externally through registers in the "General Register Files", while the other two are controlled through the "Configuration and Test Interface" inside their DSI controller's io-memory area. The Rockchip dw-dsi controller already controls these dphys for the TX case in the driver, but when we want to also allow configuration for RX to the ISP from the media subsystem we need to expose phy- functionality instead. So add a bit of infrastructure to allow the dsi driver to work as a phy and make sure it can be only one or the other at a time. Similarly as the dsi-controller will be part of the drm-graph when active, add an empty component to the drm-graph when in phy-mode to make the rest of the drm-graph not wait for it.
