Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config DRM_APPLETBDRM
	tristate "DRM support for Apple Touch Bars"
	depends on DRM && USB && MMU
	depends on X86 || COMPILE_TEST
	select DRM_GEM_SHMEM_HELPER
	select DRM_KMS_HELPER
	help
	  Say Y here if you want support for the display of Touch Bars on x86
	  MacBook Pros.

	  To compile this driver as a module, choose M here: the
	  module will be called appletbdrm.

config DRM_ARCPGU
	tristate "ARC PGU"
	depends on DRM && OF
	select DRM_CLIENT_SELECTION
	select DRM_GEM_DMA_HELPER
	select DRM_KMS_HELPER
	help
	  Choose this option if you have an ARC PGU controller.

	  If M is selected the module will be called arcpgu.

config DRM_BOCHS
	tristate "DRM Support for bochs dispi vga interface (qemu stdvga)"
	depends on DRM && PCI && MMU
	select DRM_CLIENT_SELECTION
	select DRM_GEM_SHMEM_HELPER
	select DRM_KMS_HELPER
	help
	  This is a KMS driver for qemu's stdvga output. Choose this option
	  for qemu.

	  If M is selected the module will be called bochs.

config DRM_CIRRUS_QEMU
	tristate "Cirrus driver for QEMU emulated device"
	depends on DRM && PCI
	select DRM_CLIENT_SELECTION
	select DRM_KMS_HELPER
	select DRM_GEM_SHMEM_HELPER
	help
	 This is a KMS driver for emulated cirrus device in qemu.
	 It is *NOT* intended for real cirrus devices. This requires
	 the modesetting userspace X.org driver.

	 Cirrus is obsolete, the hardware was designed in the 90ies
	 and can't keep up with todays needs.  More background:
	 https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/

	 Better alternatives are:
	   - stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
	   - qxl (DRM_QXL, qemu -vga qxl, works best with spice)
	   - virtio (DRM_VIRTIO_GPU), qemu -vga virtio)

config DRM_GM12U320
	tristate "GM12U320 driver for USB projectors"
	depends on DRM && USB && MMU
	select DRM_CLIENT_SELECTION
	select DRM_KMS_HELPER
	select DRM_GEM_SHMEM_HELPER
	help
	 This is a KMS driver for projectors which use the GM12U320 chipset
	 for video transfer over USB2/3, such as the Acer C120 mini projector.

config DRM_PANEL_MIPI_DBI
	tristate "DRM support for MIPI DBI compatible panels"
