The texture base address registers are in units of 256 bytes.
The original CS checker treated these offsets as bytes, so the
original check was wrong. I fixed the units in a patch during
the 2.6.36 cycle, but this ended up breaking some existing
userspace (probably due to a bug in either userspace texture allocation
or the drm texture mipmap checker). So for now, until we come
up with a better fix, just warn if the mipmap size it too large.
This will keep existing userspace working and it should be just
as safe as before when we were checking the wrong units. These
are GPU MC addresses, so if they fall outside of the VRAM or
GART apertures, they end up at the GPU default page, so this should
be safe from a security perspective.
v2: Just disable the warning. It just spams the log and there's
nothing the user can do about it.

There has been periodic evidence that LVDS, on at least some
panels, prefers the dividers selected by the legacy pll algo.
This patch forces the use of the legacy pll algo on RV620
LVDS panels. The old behavior (new pll algo) can be selected
by setting the new_pll module parameter to 1.

This commit fixes bogus CS rejection if it contains a sequence
of the following operations:
- Set the color buffer 0. track->cb[i].robj becomes non-NULL.
- Render.
- Set a larger zbuffer than the previously-set color buffer.
- Set a larger scissor area as well.
- Set the color channel mask to 0 to do depth-only rendering.
- Render. --> rejected, because track->cb[i].robj remained non-NULL,
therefore the conditional checking for the color channel mask and
friends is not performed, and the larger scissor area causes
the rejection.
This fixes bugs:

- https://bugs.freedesktop.org/show_bug.cgi?id=28869
And maybe some others which seem to look the same.

One subtest of mesa/demos/gltestperf takes 9 seconds to complete,
so to prevent an unnecessary gpu reset followed by a hardlock, I am
increasing the interval to 10 seconds after which a GPU is considered
in a locked-up state. This is on RV530. However, with a little slower GPU,
we would surpass the interval easily, so this is not a good fix
for gltestperf.
Nevertheless, this commit also fixes hardlocks in the applications which
render at speed of less than 1 frame per second, where the whole frame
consists of only one command stream. The game Tiny & Big is an example.
This bar is now lowered to 0.1 fps.
Now the question comes down to whether we should (often unsuccessfully)
reset the GPU at all? Once we have stable enough drivers, we won't have to.
Has the time come already?
If possible, this commit should go to stable as well.

Destructive load-detection is very expensive and due to failings
elsewhere can trigger system wide stalls of up to 600ms. A simple
first step to correcting this is not to invoke such an expensive
and destructive load-detection operation automatically.

This code was originally for forcing some clocks on certain asics.
However, this code was later moved to asic specific functions
for all of the affected asics. The only users of the original
code at this point were r600, rv770, and evergreen and the code
was not relevant for those asics. So, remove it.

If the connector is eDP, it can only be DP, not TMDS.
Always set the detected sink type. If the sink is
detected as non-DP, but there is no EDID, you can still
manually force the port on. If the sink type is DP
and there's no DPCD, there's no way to force the monitor
on since you need both ends to train the link.

(v2)
With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory.
This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation.
Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau.
