The simpledrm driver is a DRM driver for simple-framebuffer framebuffers as provided by the kernel's boot code. This driver enables basic graphical output on many different graphics devices that are provided by the platform (e.g., EFI, VESA, embedded framebuffers). With the kernel's simple-framebuffer infrastructure, the kernel receives a pre-configured framebuffer from the system (i.e., firmware, boot loader). 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 actual modesetting is possible. A firmware framebuffer might also be specified via device-tree files. If no device platform data is given, try the DT device node. Make sure required hardware clocks and regulators are enabled while the firmware framebuffer is in use. The basic code has been taken from the simplefb driver and adapted to DRM. Clocks are released automatically via devres helpers. The drivers displays a console on simpledrm's framebuffer. The default framebuffer 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 creation v2: * 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 <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> # fbdev support Acked-by: Maxime Ripard <maxime@cerno.tech> Tested-by: nerdopolis <bluescreen_avenger@verizon.net> Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-5-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-6-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-7-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-8-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-9-tzimmermann@suse.de

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:

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)

DRM driver for simple platform-provided framebuffers.
|
|
|
|
This driver assumes that the display hardware has been initialized
|
|
by the firmware or bootloader before the kernel boots. Scanout
|
|
buffer, size, and display format must be provided via device tree,
|
|
UEFI, VESA, etc.
|
|
|
|
On x86 and compatible, you should also select CONFIG_X86_SYSFB to
|
|
use UEFI and VESA framebuffers.
