Previously we were calling back move_notify in error path when the

When destroying the bo set the new mem placement as NULL when calling
back in the driver.
Updating nouveau to deal with NULL placement properly.
v2: reserve the object before calling move_notify in bo destroy path
at that point ttm should be the only piece of code interacting
with the object so atomic_set is safe here.
v3: callback move notify only once the bo is in its new position

Subject: [PATCH] drm: Make the per-driver file_operations struct const
The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.
This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

This changes the meaning of what we reported as "core" clock previously.
The shader/rop units are allegedly supposed to be run at the base clock

the shaders *do* run at it), and the geometric clock as "core".

Sometimes we want to know whether a buffer is busy and wait for it (bo_wait).
However, sometimes it would be more useful to be able to query whether
a buffer is busy and being either read or written, and wait until it's stopped
being either read or written. The point of this is to be able to avoid
unnecessary waiting, e.g. if a GPU has written something to a buffer and is now
reading that buffer, and a CPU wants to map that buffer for read, it needs to
only wait for the last write. If there were no write, there wouldn't be any
waiting needed.
This, or course, requires user space drivers to send read/write flags
with each relocation (like we have read/write domains in radeon, so we can
actually use those for something useful now).
Now how this patch works:
The read/write flags should passed to ttm_validate_buffer. TTM maintains
separate sync objects of the last read and write for each buffer, in addition
to the sync object of the last use of a buffer. ttm_bo_wait then operates
with one the sync objects.

There's a number of things not implemented by this fuc currently, but

implement it if required.
This has been tested on 0xc0/0xc4 thus far, and from what I could tell
it worked as well as NVIDIA's. It's also been tested on 0xc1, but even
with NVIDIA's fuc that chipset doesn't work correctly with nouveau yet.

There's issues with certain 3D apps still, unknown whether this is a kernel
issue or not.. It does appear that it may be in the 3D driver however.

Fixes DMAR faults during accel, more than likely a similar problem to what
was solved on nv50 previously.

The DDX modifies DMA_SEMAPHORE on nv50 in order to implement sync-to-vblank,
things will go very wrong for cross-channel sync after this.

While parsing the perf table, there is no check if
the num of entries read from the vbios is less than
the currently allocated number.
In case of a buggy vbios this will cause overwriting
of kernel memory, causing aditional problems.
Add a simple check in order to prevent the case

PCI(E)GART isn't quite stable it seems, fall back to old method until I get
the time to sort it out properly.

Should hopefully get modesetting at least from this, it appears these are
GF119 chipsets. Accel will come eventually, once I order a board.

When xorg state tracker wants to hide the cursor it calls set_cursor
with NULL buffer_handle and size=0x0, but nouveau refuses to hide it
because size is not 64x64... which is a bit odd. Both radeon and intel
check buffer_handle before validating size of cursor, so make nouveau
implementation consistent with them.

The core/mem/shader clocks don't support the fractional feedback divider,
causing our calculated clocks to be off by quite a lot in some cases. To
solve this we will switch to a search-based algorithm when fN is NULL.
For my NVA8 at PL3, this actually generates identical cooefficients to
the binary driver. Hopefully that's a good sign, and that does not
break VPLL calculation for someone..

Hopefully this is how we're supposed to correctly handle when the RAMCFG
strap is above the number of entries in timing-related tables.
It's rather difficult to confirm without finding a configuration where
the ram restrict table doesn't map 8-15 back onto 0-7 anyway. There's
not a single vbios in the repo which is configured differently..
In any case, this is probably still better than potentially reading
outside of the bounds of various tables..
