drm/tiny: add driver for Apple Touch Bars in x86 Macs The Touch Bars found on x86 Macs support two USB configurations: one where the device presents itself as a HID keyboard and can display predefined sets of keys, and one where the operating system has full control over what is displayed. This commit adds support for the display functionality of the second configuration. Functionality for the first configuration has been merged in the HID tree. Note that this driver has only been tested on T2 Macs, and only includes the USB device ID for these devices. Testing on T1 Macs would be appreciated. Credit goes to Ben (Bingxing) Wang on GitHub for reverse engineering most of the protocol. Also, as requested by Andy, I would like to clarify the use of __packed structs in this driver: - All the packed structs are aligned except for appletbdrm_msg_information. - We have to pack appletbdrm_msg_information since it is requirement of the protocol. - We compared binaries compiled by keeping the rest structs __packed and not __packed using bloat-o-meter, and __packed was not affecting code generation. - To maintain consistency, rest structs have been kept __packed. I would also like to point out that since the driver was reverse-engineered the actual data types of the protocol might be different, including, but not limited to, endianness.

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.

drm/bochs: Use GEM SHMEM helpers for memory management Replace GEM VRAM with GEM SHMEM in bochs. The new memory manager stores buffer objects in system memory. Makes the driver's memory management more reliably. Most of the changes are hidden in external helpers that allocate buffers. Replacing DRM_GEM_VRAM_DRIVER with DRM_GEM_SHMEM_DRIVER_OPS swaps these. With GEM VRAM, the video memory was updated directly by the DRM client. The biggest change within bochs is in atomic_update, which now updates video memory via memcpy() from the BO in system memory. Shadow-plane helpers maintaining the pointers to the buffer's data, so bochs doesn't have to. The update is triggered by each page flip's call to the framebuffer's dirty helper. The driver supports damage clipping to minimize memcpy() overhead. The advantage of GEM SHMEM is that it makes memory management more reliable. Given DRM's double buffering during page flips, the minimum amount of video memory is three times the maximum consumption in some pathological cases. For example, if the maximum size of a GEM buffer is 1920x1080-32 (i.e., 32-bit FullHD), the buffer size is 8 MiB. Display hardware has to provide at lease 24 MiB to reliably page flip such configurations. This cannot always be guaranteed and bochs already contains code to rule out <4 MiB configurations. With GEM SHMEM, only 8 MiB of video memory are required for the given example. Unsupported modes can be sorted out easily.

PCI: Add CONFIG_MMU dependency It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.

drm/shmem-helper: Switch to vmf_insert_pfn We want to stop gup, which isn't the case if we use vmf_insert_page and VM_MIXEDMAP, because that does not set pte_special. The motivation here is to stop get_user_pages from working on buffer object mmaps in general. Quoting some discussion with Thomas: On Thu, Jul 22, 2021 at 08:22:43PM +0200, Thomas Zimmermann wrote: > Am 13.07.21 um 22:51 schrieb Daniel Vetter: > > We want to stop gup, which isn't the case if we use vmf_insert_page > > What is gup? get_user_pages. It pins memory wherever it is, which badly wreaks at least ttm and could also cause trouble with cma allocations. In both cases becaue we can't move/reuse these pages anymore. Now get_user_pages fails when the memory isn't considered "normal", like with VM_PFNMAP and using vm_insert_pfn. For consistency across all dma-buf I'm trying (together with Christian König) to roll this out everywhere, for fewer surprises. E.g. for 5.14 iirc we merged a patch to do the same for ttm, where it closes an actual bug (ttm gets really badly confused when there's suddenly pinned pages where it thought it can move them). cma allcoations already use VM_PFNMAP (because that's what dma_mmap is using underneath), as is anything that's using remap_pfn_range. Worst case we have to revert this patch for shmem helpers if it breaks something, but I hope that's not the case. On the ttm side we've also had some fallout that we needed to paper over with clever tricks. v2: With this shmem gem helpers now definitely need CONFIG_MMU (0day) v3: add more depends on MMU. For usb drivers this is a bit awkward, but really it's correct: To be able to provide a contig mapping of buffers to userspace on !MMU platforms we'd need to use the cma helpers for these drivers on those platforms. As-is this wont work. Also not exactly sure why vm_insert_page doesn't go boom, because that definitely wont fly in practice since the pages are non-contig to begin with. v4: Explain the entire motivation a lot more (Thomas) Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210812131412.2487363-2-daniel.vetter@ffwll.ch

drm/tiny: Add MIPI DBI compatible SPI driver Add a driver that will work with most MIPI DBI compatible SPI panels. This avoids adding a driver for every new MIPI DBI compatible controller that is to be used by Linux. The 'compatible' Device Tree property with a '.bin' suffix will be used to load a firmware file that contains the controller configuration. Example (driver will load sainsmart18.bin): display@0 { compatible = "sainsmart18", "panel-mipi-dbi-spi"; ... }; v5: - kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam) - kconfig: Add select VIDEOMODE_HELPERS (Sam) - kconfig: Add wiki url in the description (Sam) - Split out and use of_get_drm_panel_display_mode()(Sam) - Only use the first compatible to look for a firmware file since the binding mandates 2 compatibles. - Make having a firmware file mandatory so we can print an error message if it's missing to improve the user experience. It's very unlikely that a controller doesn't need to be initialized and if it doesn't, it's possible to have a firmware file containing only a DCS NOP. v4: - Move driver to drm/tiny where the other drivers of its kind are located. The driver module will not be shared with a future DPI driver after all. v3: - Move properties to DT (Maxime) - The MIPI DPI spec has optional support for DPI where the controller is configured over DBI. Rework the command functions so they can be moved to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver v2: - Drop model property and use compatible instead (Rob) - Add wiki entry in MAINTAINERS Acked-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-6-noralf@tronnes.org

drm/tiny: pixpaper: add explicit dependency on MMU The DRM_GEM_SHMEM_HELPER helper requires MMU enabled because it uses vmf_insert_pfn() in its mmap implementation. On NOMMU configurations (e.g. some RISC-V randconfig builds), this symbol is unavailable and selecting DRM_GEM_SHMEM_HELPER causes a modpost undefined reference: ERROR: modpost: "vmf_insert_pfn" [drivers/gpu/drm/drm_shmem_helper.ko] undefined! Normally, Kconfig prevents this helper from being selected when CONFIG_MMU=n. However, in some randconfig builds (such as those used by 0day CI), select statements can override unmet dependencies, triggering the issue. Add an explicit dependency on MMU to DRM_PIXPAPER to prevent this.

The reason for this is that DRM_KMS_FB_HELPER selects FB instead of depending on it. The tinydrm drivers have somehow gotten away with depending on BACKLIGHT_CLASS_DEVICE because DRM_TINYDRM selects DRM_KMS_HELPER and the drivers depend on that symbol. An audit shows that all DRM drivers that select DRM_KMS_HELPER and use BACKLIGHT_CLASS_DEVICE, selects it: DRM_TILCDC, DRM_GMA500, DRM_SHMOBILE, DRM_NOUVEAU, DRM_FSL_DCU, DRM_I915, DRM_RADEON, DRM_AMDGPU, DRM_PARADE_PS8622 Documentation/kbuild/kconfig-language.txt has a note regarding select: 1. 'select should be used with care since it doesn't visit dependencies.' This is not a problem since BACKLIGHT_CLASS_DEVICE doesn't have any dependencies. 2. 'In general use select only for non-visible symbols' BACKLIGHT_CLASS_DEVICE is user visible. The real solution to this would be to have DRM_KMS_FB_HELPER depend on the user visible symbol FB. That is a can of worms I'm not willing to tackle. I fear that such a change will result in me handling difficult fallouts for the next weeks. So I'm following DRM suite here.

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.

The reason for this is that DRM_KMS_FB_HELPER selects FB instead of depending on it. The tinydrm drivers have somehow gotten away with depending on BACKLIGHT_CLASS_DEVICE because DRM_TINYDRM selects DRM_KMS_HELPER and the drivers depend on that symbol. An audit shows that all DRM drivers that select DRM_KMS_HELPER and use BACKLIGHT_CLASS_DEVICE, selects it: DRM_TILCDC, DRM_GMA500, DRM_SHMOBILE, DRM_NOUVEAU, DRM_FSL_DCU, DRM_I915, DRM_RADEON, DRM_AMDGPU, DRM_PARADE_PS8622 Documentation/kbuild/kconfig-language.txt has a note regarding select: 1. 'select should be used with care since it doesn't visit dependencies.' This is not a problem since BACKLIGHT_CLASS_DEVICE doesn't have any dependencies. 2. 'In general use select only for non-visible symbols' BACKLIGHT_CLASS_DEVICE is user visible. The real solution to this would be to have DRM_KMS_FB_HELPER depend on the user visible symbol FB. That is a can of worms I'm not willing to tackle. I fear that such a change will result in me handling difficult fallouts for the next weeks. So I'm following DRM suite here.

drm/tinydrm/Kconfig: drivers: Select BACKLIGHT_CLASS_DEVICE The mipi_dbi helper is missing a dependency on DRM_KMS_HELPER and putting that in revealed this problem: drivers/video/fbdev/Kconfig:12:error: recursive dependency detected! drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:75: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:69: symbol DRM_KMS_HELPER is selected by TINYDRM_MIPI_DBI drivers/gpu/drm/tinydrm/Kconfig:11: symbol TINYDRM_MIPI_DBI is selected by TINYDRM_HX8357D drivers/gpu/drm/tinydrm/Kconfig:15: symbol TINYDRM_HX8357D depends on BACKLIGHT_CLASS_DEVICE drivers/video/backlight/Kconfig:144: symbol BACKLIGHT_CLASS_DEVICE is selected by FB_BACKLIGHT drivers/video/fbdev/Kconfig:187: symbol FB_BACKLIGHT depends on FB A symbol that selects DRM_KMS_HELPER can not depend on BACKLIGHT_CLASS_DEVICE. The reason for this is that DRM_KMS_FB_HELPER selects FB instead of depending on it. The tinydrm drivers have somehow gotten away with depending on BACKLIGHT_CLASS_DEVICE because DRM_TINYDRM selects DRM_KMS_HELPER and the drivers depend on that symbol. An audit shows that all DRM drivers that select DRM_KMS_HELPER and use BACKLIGHT_CLASS_DEVICE, selects it: DRM_TILCDC, DRM_GMA500, DRM_SHMOBILE, DRM_NOUVEAU, DRM_FSL_DCU, DRM_I915, DRM_RADEON, DRM_AMDGPU, DRM_PARADE_PS8622 Documentation/kbuild/kconfig-language.txt has a note regarding select: 1. 'select should be used with care since it doesn't visit dependencies.' This is not a problem since BACKLIGHT_CLASS_DEVICE doesn't have any dependencies. 2. 'In general use select only for non-visible symbols' BACKLIGHT_CLASS_DEVICE is user visible. The real solution to this would be to have DRM_KMS_FB_HELPER depend on the user visible symbol FB. That is a can of worms I'm not willing to tackle. I fear that such a change will result in me handling difficult fallouts for the next weeks. So I'm following DRM suite here.

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`.
