mgag200: initial g200se driver (v2) This is a driver for the G200 server engines chips, it doesn't driver any of the Matrix G series desktop cards. It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards. Its based on previous work done my Matthew Garrett but remodelled to follow the same style and flow as the AST server driver. It also works along the same lines as the AST server driver wrt memory management. There is no userspace driver planned, xf86-video-modesetting should be used. It also appears these GPUs have no ARGB hw cursors. v2: add missing tagfifo reset + G200 SE memory bw setup pieces. Signed-off-by: Dave Airlie <airlied@redhat.com>

drm/mgag200: Add support for G200 desktop cards This patch adds support for G200 desktop cards. We can reuse the whole memory and modesetting code. A few PCI and DAC register values have to be updated accordingly. The most significant change is in the PLL setup. The driver parses the device's BIOS to retrieve clock limits and reference clocks. With no BIOS found, safe defaults are being used. v2: * copy BIOS ROM to system memory and access with regular load/store; resolves potential HW limitations * fix some stray whitespaces Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Co-developed-by: Egbert Eich <eich@suse.com> Signed-off-by: Egbert Eich <eich@suse.com> Co-developed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200730102844.10995-9-tzimmermann@suse.de

drm/mgag200: Replace VRAM helpers with SHMEM helpers The VRAM helpers managed the framebuffer memory for mgag200. This came with several problems, as some MGA device require the scanout address to be located at VRAM offset 0. It's incompatible with the page-flip semantics of DRM's atomic modesettting. With atomic modesetting, old and new framebuffers have to be located in VRAM at the same time. So at least one of them has to reside at a non-0 offset. This patch replaces VRAM helpers with SHMEM helpers. GEM SHMEM buffers reside in system memory, and are shadow-copied into VRAM during page flips. The shadow copy always starts at VRAM offset 0. v2: * revert dev->pdev changes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: John Donnelly <John.p.donnelly@oracle.com> Acked-by: Emil Velikov <emil.velikov@collabora.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200515083233.32036-16-tzimmermann@suse.de

This is a KMS driver for Matrox G200 chips. It supports the original
MGA G200 desktop chips and the server variants. It requires 0.3.0
of the modesetting userspace driver, and a version of mga driver
that will fail on KMS enabled devices.
