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/Kconfig

c3ac343c - drm/bochs: Use GEM SHMEM helpers for memory management

Mon, 02 Sep 2024 10:53:46 +0000

drm/bochs: Use GEM SHMEM helpers for memory managementReplace GEM VRAM with GEM SHMEM in bochs. The new memory managerstores buffer objects in system memory. Makes the driver's memorymanagement more reliably.Most of the changes are hidden in external helpers that allocatebuffers. Replacing DRM_GEM_VRAM_DRIVER with DRM_GEM_SHMEM_DRIVER_OPSswaps these. With GEM VRAM, the video memory was updated directly bythe DRM client. The biggest change within bochs is in atomic_update,which now updates video memory via memcpy() from the BO in systemmemory. Shadow-plane helpers maintaining the pointers to the buffer'sdata, so bochs doesn't have to. The update is triggered by each pageflip's call to the framebuffer's dirty helper. The driver supportsdamage clipping to minimize memcpy() overhead.The advantage of GEM SHMEM is that it makes memory managementmore reliable. Given DRM's double buffering during page flips, theminimum amount of video memory is three times the maximum consumptionin some pathological cases. For example, if the maximum size of a GEMbuffer is 1920x1080-32 (i.e., 32-bit FullHD), the buffer size is8 MiB. Display hardware has to provide at lease 24 MiB to reliablypage flip such configurations. This cannot always be guaranteed andbochs already contains code to rule out <4 MiB configurations. WithGEM SHMEM, only 8 MiB of video memory are required for the givenexample. Unsupported modes can be sorted out easily.Signed-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20240902105546.792625-9-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/tiny/Kconfig
