The TTM device release will try to evict anything in VRAM to GART
memory, but this will fail since sgdma has already been taken down.
This causes an infinite loop in kernel mode on module unload.
It usually doesn't happen because there aren't any buffer on close.
However, if the GPU is locked up, this condition is easily triggered.
This patch fixes it in the simplest way possible by cleaning VRAM
right before cleaning SGDMA memory.

drm/nouveau: Acknowledge DMA_VTX_PROTECTION PGRAPH interrupts
Currently Nouveau is unable to dismiss DMA_VTX_PROTECTION errors,
which results in an infinite loop in the interrupt handler.
These errors are caused both by bugs in the Gallium driver and by
user-specified index buffers with out of bounds indices.
By mmio-tracing the nVidia drivers, I found out how this is done.
On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000,
always getting the value 4, and then writes 4 back to 0x402000.
This patch adds that logic by reading 0x402000 and writing the same
value back.
It's unclear what should happen if the value read is not 4, and
the current approach might not be the correct one.
To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining
ELTOBJ to 1 and replacing indices with huge out of bounds integers.
Without this patch, the GPU and/or kernel should lock up.
With this patch, it should misrender as expected but not lock up.
The errors are still logged since they are useful for development.
This has been tested on NV49 and may not work on other cards.
To find out how things work on other cards, run the aforementioned
test using the blob with mmiotrace and grep for a read of the PGRAPH
source register.

drm/nouveau: check pushbuffer bounds in ioctl
Currently there is no check that the pushbuffer request bounds are inside
the TTM BO.
This allows to instruct the kernel to do relocations on user-selected
addresses, since the relocation bounds checking relies on the request
bounds.
This can oops the kernel accidentally and is easily exploitable.
This patch adds bound checking and alignment checking for ->offset and
->nr_dwords.
It also makes some variables unsigned, which should have no effect,
but prevents possible bounds checking problems.

drm/nouveau: trust init table registers are safe
Apparently the original reason for checking this was there were known
register accesses that caused hangs on some chipsets. This was more
than likely because of incorrect parsing of previous opcodes, and I
hardly think aborting a script half way through is going to be any
better (in fact, we have had bug reports where this has been the cause
of s/r failures among other things).
This patch (which has been in Fedora 12 for a long time now) removes
all checking for known register ranges, and just leaves the check to
ensure the access is within the mapped aperture to avoid an oops.

Currently Nouveau will unvalidate all buffers if it is forced to wait on

This patch fixes this bug by taking the fence object out of validate_op

and unref'ed unconditionally.

drm/nv50: prevent a possible ctxprog hang
The below is mainly an educated guess at what's going on, docs would
sure be handy... NVIDIA? :P
It appears it's possible for a ctxprog to run even while a GPU exception
is pending. The GF8 and up ctxprogs appear to have a small snippet of
code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:
if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}
I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us). This patch causes the driver to
clear the flag during the PGRAPH IRQ handler.
