0670c2f5 - drm/tiny: add driver for Apple Touch Bars in x86 Macs

Wed, 26 Feb 2025 16:04:36 +0000

drm/tiny: add driver for Apple Touch Bars in x86 MacsThe Touch Bars found on x86 Macs support two USB configurations: onewhere the device presents itself as a HID keyboard and can displaypredefined sets of keys, and one where the operating system has fullcontrol over what is displayed.This commit adds support for the display functionality of the secondconfiguration. Functionality for the first configuration has beenmerged in the HID tree.Note that this driver has only been tested on T2 Macs, and only includesthe USB device ID for these devices. Testing on T1 Macs would beappreciated.Credit goes to Ben (Bingxing) Wang on GitHub for reverse engineeringmost of the protocol.Also, as requested by Andy, I would like to clarify the use of __packedstructs 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-engineeredthe actual data types of the protocol might be different, including, butnot limited to, endianness.Link: https://github.com/imbushuo/DFRDisplayKmSigned-off-by: Kerem Karabay Co-developed-by: Atharva Tiwari Signed-off-by: Atharva Tiwari Co-developed-by: Aditya Garg Signed-off-by: Aditya Garg Signed-off-by: Aun-Ali Zaidi Reviewed-by: Thomas Zimmermann Signed-off-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/FCAC702C-F84A-47F9-8C78-BBBB34D08500@live.com List of files: /linux-6.15/drivers/gpu/drm/tiny/Makefile

c8a17756 - drm/ofdrm: Add ofdrm for Open Firmware framebuffers

Tue, 11 Oct 2022 15:07:08 +0000

drm/ofdrm: Add ofdrm for Open Firmware framebuffersOpen Firmware provides basic display output via the 'display' node.DT platform code already provides a device that represents the node'sframebuffer. Add a DRM driver for the device. The display mode andcolor format is pre-initialized by the system's firmware. Runtimemodesetting via DRM is not possible. The display is useful duringearly boot stages or as error fallback.Similar functionality is already provided by fbdev's offb driver,which is insufficient for modern userspace. The old driver includessupport for BootX device tree, which can be found on old 32-bitPowerPC Macintosh systems. If these are still in use, thefunctionality can be added to ofdrm or implemented in a newdriver. As with simpledrm, the fbdev driver cannot be selected ifofdrm is already enabled.Two notable points about the driver: * Reading the framebuffer aperture from the device tree is notreliable on all systems. Ofdrm takes the heuristics and a commentfrom offb to pick the correct range. * No resource management may be tied to the underlying PCI device.Otherwise the handover to the native driver will fail with a resourceconflict. PCI management is therefore done as part of the platformdevice's cleanup.The driver has been tested on qemu's ppc64le emulation. The devicehand-over has been tested with bochs.v5: * use drm_atomic_helper_check_crtc_primary_plane()v4: * set preferred depth to the correct value * set bpp value for console emulation * output scanout-buffer parameters with drm_dbg()v3: * reintegrate FWFB helpers into ofdrm * use damage iterator * sync GEM BOs with drm_gem_fb_{begin,end}_cpu_access() * fix various atomic_check helpers * remove CRTC atomic_{enable,disable} (Javier) * compute stride with drm_format_info_min_pitch() (Daniel)v2: * removed simple-pipe helpers * built driver on top of FWFB helpers * merged all init code into single function * make PCI support optional (Michal) * support COMPILE_TEST (Javier)Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas convertLink: https://patchwork.freedesktop.org/patch/msgid/20221011150712.3928-2-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/tiny/Makefile

0e65e2e6 - drm/tiny: Add MIPI DBI compatible SPI driver

Sun, 27 Feb 2022 12:47:13 +0000

drm/tiny: Add MIPI DBI compatible SPI driverAdd a driver that will work with most MIPI DBI compatible SPI panels.This avoids adding a driver for every new MIPI DBI compatible controllerthat is to be used by Linux. The 'compatible' Device Tree property witha '.bin' suffix will be used to load a firmware file that contains thecontroller 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 driverv2:- Drop model property and use compatible instead (Rob)- Add wiki entry in MAINTAINERSAcked-by: Maxime Ripard Reviewed-by: Sam Ravnborg Signed-off-by: Noralf Trønnes Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-6-noralf@tronnes.org List of files: /linux-6.15/drivers/gpu/drm/tiny/Makefile

11e8f5fd - drm: Add simpledrm driver

Fri, 30 Apr 2021 10:58:35 +0000

drm: Add simpledrm driverThe simpledrm driver is a DRM driver for simple-framebuffer framebuffersas provided by the kernel's boot code. This driver enables basicgraphical output on many different graphics devices that are providedby the platform (e.g., EFI, VESA, embedded framebuffers).With the kernel's simple-framebuffer infrastructure, the kernel receivesa pre-configured framebuffer from the system (i.e., firmware, bootloader). It creates a platform device to which simpledrm attaches.The system's framebuffer consists of a memory range, size and format.Based on these values, simpledrm creates a DRM devices. No actualmodesetting is possible.A firmware framebuffer might also be specified via device-tree files. Ifno device platform data is given, try the DT device node.Make sure required hardware clocks and regulators are enabled while thefirmware framebuffer is in use. The basic code has been taken from thesimplefb driver and adapted to DRM. Clocks are released automaticallyvia devres helpers.The drivers displays a console on simpledrm's framebuffer. The defaultframebuffer format is being used.v4: * disable simplefb if simpledrm has been selected (Maxime)v3: * add disable function that clears screen to black (Daniel) * set shadow buffering only for fbdev emulation * set platform-driver data during device creationv2: * rename driver to simpledrm * add dri-devel to MAINTAINERS entry * put native format first in primary-plane format list (Daniel) * inline simplekms_device_cleanup() (Daniel) * use helpers for shadow-buffered planes * fix whitespace errors * add Device Tree match table * clean-up parser wrappers * use strscpy()Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter # fbdev supportAcked-by: Maxime Ripard Tested-by: nerdopolis Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-5-tzimmermann@suse.deLink: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-6-tzimmermann@suse.deLink: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-7-tzimmermann@suse.deLink: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-8-tzimmermann@suse.deLink: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-9-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/tiny/Makefile
