wanted from slice max and use that to check it fits inside the BO, however

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.

- 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

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)

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.

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.

Jesse's initial patch commit said:
"At panic time (i.e. when oops_in_progress is set) we should try a bit
harder to update the screen and make sure output gets to the VT, since
some drivers are capable of flipping back to it.
So make sure we try to unblank and update the display if called from a
panic context."
I've enhanced this to add a flag to the vc that console layer can set to
indicate they want this behaviour to occur. This also adds support to
fbcon for that flag and adds an fb flag for drivers to indicate they want
to use the support. It enables this for KMS drivers.

This fixes a regression caused by b2ea4aa67b
due to the way shared ddc with multiple digital connectors was handled.
You generally have two cases where DDC lines are shared:
- HDMI + VGA
- HDMI + DVI-D
HDMI + VGA is easy to deal with because you can check the EDID for the
to see if the attached monitor is digital. A shared DDC line with two
digital connectors is more complex. You can't use the hdmi bits in the
EDID since they may not be there with DVI<->HDMI adapters. In this case
all we can do is check the HPD pins to see which is connected as we have
no way of knowing using the EDID.

aperture.
3. The GART page table has to be aligned to the boundary equal to the size of the table.

There is a regression from 2.6.34 related to the recent radeon power
management changes, caused by attempting to cancel a delayed work
item that's never been scheduled. However, the code as is has some
other issues potentially leading to visible problems.
First, the mutex around cancel_delayed_work() in radeon_pm_suspend()
doesn't really serve any purpose, because cancel_delayed_work() only
tries to delete the work's timer. Moreover, it doesn't prevent the
work handler from running, so the handler can do some wrong things if
it wins the race and in that case it will rearm itself to do some
more wrong things going forward. So, I think it's better to wait for
the handler to return in case it's already been queued up for
execution. Also, it should be prevented from rearming itself in that
case.
Second, in radeon_set_pm_method() the cancel_delayed_work() is not
sufficient to prevent the work handler from running and queing up
itself for the next run (the failure scenario is that
cancel_delayed_work() returns 0, so the handler is run, it waits on
the mutex and then rearms itself after the mutex has been released),
so again the work handler should be prevented from rearming itself in
that case..
Finally, there's a potential deadlock in radeon_pm_fini(), because
cancel_delayed_work_sync() is called under rdev->pm.mutex, but the
work handler tries to acquire the same mutex (if it wins the race).
Fix the issues described above.

This patch is a combination of the previous two profile
patches, but without the index bugs. It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same. For the low profile case, choose
the lower clock mode.

- Separate dynpm and profile based power management methods. You can select the pm method
by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
"default" - default clocks
"auto" - select between low and high based on ac/dc state
"low" - DC, low power mode
"high" - AC, performance mode
The current base profile is "default", but it should switched to "auto" once we've tested
on more systems. Switching the state is a matter of echoing the requested profile to
power_profile in sysfs. The lowest power states are selected automatically when dpms turns
the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment. We can revisit this later once we
have basic pm in.
- Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure
display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option. It's now selectable via sysfs.

Add two new sysfs attributes:
- dynpm
- power_state
Echoing 0/1 to dynpm disables/enables dynamic power management.
The driver scales the sclk dynamically based on the number of
queued fences. dynpm only scales sclk dynamically in single head
mode.
Echoing x.y to power_state selects a static power state (x) and clock
mode (y). This allows you to statically select a power state and clock
mode. Selecting a static clock mode will disable dynpm.

patch change the reset code to avoid hard lockup. The GPU reset
is failing most of the time but at least user can log in remotely

Two issues were leading to hard lockup :
- Writting to the scratch register lead to hard lockup most likely
because the write back mecanism is in fuzy state after GPU lockup.
- Resetting the GPU memory controller and not reinitializing it
after leaded to hard lockup. We did only reinitialize in case of
successfull reset thus unsuccessfull reset quickly leaded to hard
