drm/ast: Fix incorrect register check for DRAM width

2016-03-02T07:50:17+00:00

During DRAM initialization on certain ASpeed devices, an incorrect
bit (bit 10) was checked in the "SDRAM Bus Width Status" register
to determine DRAM width.

Query bit 6 instead in accordance with the Aspeed AST2050 datasheet v1.05.

drm: Pass 'name' to drm_encoder_init()

2015-12-11T08:13:20+00:00

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()

2015-11-24T10:47:38+00:00

Drivers shouldn't clobber the passed in addfb ioctl parameters.
i915 was doing just that. To prevent it from happening again,
pass the struct around as const, starting all the way from
internal_framebuffer_create().

drm: Remove unused fbdev_list members

2015-11-24T10:41:52+00:00

I noticed that intel_fbdev->our_mode is unused. Introduced by
79e539453b34 ("DRM: i915: add mode setting support").

Then I noticed that intel_fbdev->fbdev_list is unused as well.
Introduced by 386516744ba4 ("drm/fb: fix fbdev object model +
cleanup properly.") in i915, nouveau and radeon.

Subsequently cargo culted to amdgpu, ast, cirrus, qxl, udl,
virtio and mgag200.

Already removed from the latter with cc59487a05b1 ("drm/mgag200:
'fbdev_list' in 'struct mga_fbdev' is not used").

Remove it from the others.

drm/ast: Initialized data needed to map fbdev memory

2015-11-11T02:27:31+00:00

Due to a missing initialization there was no way to map fbdev memory.
Thus for example using the Xserver with the fbdev driver failed.
This fix adds initialization for fix.smem_start and fix.smem_len
in the fb_info structure, which fixes this problem.

drm/ast: Don't grab dev->struct_mutex for in mmap offset ioctl

2015-08-10T11:36:55+00:00

Since David Herrmann's mmap vma manager rework we don't need to grab
dev->struct_mutex any more to prevent races when looking up the mmap
offset. Drop it and instead don't forget to use the unref_unlocked
variant (since the drm core still cares).
