The mixer driver and hdmi driver have each operation callback functions
and they is registered to hdmi common driver. Their struct names in hdmi
common driver include display, manager and overlay. It confuses to
appear whose operation and two driver cannot register same operation
callback functions at the same time. Use their struct names to driver
name.

mplayer -vo fbdev tries to create a screen that is twice as tall as the
allocated framebuffer for "doublebuffering". By default, and all in-tree
users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer
originally allocated.

The code tries various methods for retreiving the BIOS data. However
it doesn't clear the bios->data pointer between the iterations.

In some cases, the shadow() method will fail and not update bios->data
at all, which will cause us to "score" the old data and incorrectly
attribute that score to the new method. This can cause double frees
later when disposing of the unused data.

Additionally, we were not freeing the data for methods that fail the
score test (we only freed when a "best" is superseeded, not when the
new method has a lower score than the exising "best"). Fix that as well.

Under some circumstances, pci_map_rom() can return a valid mapping

This causes nouveau to try to kmalloc() a 0 sized pointer and

Looking at hibernate overwriting I though it looked like a cursor,
so I tracked down this missing piece to stop the cursor blink
timer. I've no idea if this is sufficient to fix the hibernate
problems people are seeing, but please test it.

Both radeon and nouveau have done this for a long time.

I've run this personally all night hib/resume cycles with no fails.

Userspace will check radeon version 2.14 with is bumped either
by tiling patch or stream out patch. This patch only add support
for htile relocation which should be enough for any userspace
to implement the hyperz (using htile buffer) feature.

v2: Jerome: Fix size checking for htile buffer.
v3: Jerome: Adapt on top of r600/evergreen cs checker changes,
            also check htile surface in case only stencil is

All available subchannels are now available for userspace to do with as it
pleases on NVC0+.

On all earlier chipsets, the kernel still uses a software object on subc 0
to implement the page flip completion method.  I hope to find some decent

I want to be able to use REF_CNT from other places in the kernel without
pushing a fence object onto the list of emitted fences.

The current code makes an assumption that every time the acked sequence is
bumped that there's at least one fence on the list that'll be signalled.

This will no longer be true in the near future.

There was once good reasons for wanting the drm to be able to use M2MF etc
on user channels, but they're not relevant anymore.  For the general
buffer move case, we've already lost by transferring between vram/sysmem
already so the context switching overhead is minimal in comparison.
