drm/mgag200: Add support for G200 desktop cards

2020-08-03T07:43:00Z

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 Co-developed-by: Egbert Eich Signed-off-by: Egbert Eich Co-developed-by: Takashi Iwai Signed-off-by: Takashi Iwai Reviewed-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20200730102844.10995-9-tzimmermann@suse.de

drm/mgag200: Replace VRAM helpers with SHMEM helpers

2020-05-19T07:41:34Z

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 Tested-by: John Donnelly Acked-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200515083233.32036-16-tzimmermann@suse.de
