drm/mgag200: fix build on alpha arch

2020-08-07T20:52:48+00:00

When building imgag200 for the alpha architecture it fails like this: mgag200_drv.c:233:9: error: implicit declaration of function ‘vmalloc’ 233 | bios = vmalloc(size); | ^~~~~~~ | kmalloc When building for other architectures vmalloc.h is pulled in via some other header file - for example asm-generic/io.h. Use an explicit include of vmalloc.h to fix the build.

drm/mgag200: Set PCI option register in G200SE models

The initial value of the PCI option register got lost while refactoring the driver init code. Restore the setting.

drm/mgag200: Add support for G200 desktop cards

2020-08-03T07:43:00+00:00

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: Move G200SE's unique id into model-specific data

2020-08-03T07:42:52+00:00

The unique revision id is only useful for G200SE devices. Store the value in model-specific data within struct mga_device. While at it, the patch also adds an init helper for the value.

drm/mgag200: Enable MGA mode during device register initialization

2020-08-03T07:42:27+00:00

MGA cards can run in traditional VGA mode or an enhanced MGA mode; with the latter being required for KMS. So far, MGA mode was enabled during modesetting. As it's fundamental for device operation, the patch moves it next to the device register setup.

drm/mgag200: Initialize PCI registers early during device setup

2020-08-03T07:42:19+00:00

So far, PCI option registers were initialized as part of modesetting, which is late in the process. As these registers control fundamental operation, they should be set early. The patch moves the PCI option handling into device register setup, before even the device MMIO memory is being mapped. No functional changes made. Moving the PCI code next to the device-register setup also allows to remove the has_sdram field from struct mga_device. The state is now local to the init helper.

drm/mgag200: Move register initialization into helper function

2020-08-03T07:42:11+00:00

The mgag200 driver maps registers into the address space. Move the code into a separate helper function. No functional changes. One small difference is in the handling of SDRAM/SGRAM. MGA devices can come with either SDRAM or SGRAM. So far, the driver checked for SDRAM, which is the common case. The patch moves this code into a separate helper and checks for SGRAM, which is the special case. The test itself is the same as before.
