drm/vmwgfx: Implement basic pm operations.

Currently we really only support S3, since the device doesn't support
saving of the 3D state.

On S3/S4, move all buffer objects to swappable memory and take down
GMR bindings. We need to do that from a PM notifier since we can't
do persistant memory allocations from the standard PM callbacks.

Drivers may have GPU bindings on buffers that core TTM is not aware of,
and TTM may view those buffers as ordinary system memory buffers.
Add a notifier to such drivers when TTM is about to move the buffer
contents out to swappable memory. The driver must then release any
private GPU bindings on those buffers.

drm/nouveau: Fix null deref in nouveau_fence_emit due to deleted fence

Currently Nouveau will unvalidate all buffers if it is forced to wait on
one, and then start revalidating from the beginning.  While doing so, it
destroys the operation fence, causing nouveau_fence_emit to crash.

This patch fixes this bug by taking the fence object out of validate_op
and creating it just before emit.  The fence pointer is initialized to 0
and unref'ed unconditionally.

In addition to fixing the bug, this prevents its reintroduction and
simplifies the code.

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.

drm/radeon/kms: prevent parallel AtomBIOS calls

This just adds a mutex around the atombios table execution
so we don't call it from two contexts at once.

10 years agodrm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.

drm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.

Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.

This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

drivers/gpu: Use kzalloc for allocating only one thing

Use kzalloc rather than kcalloc(1,...)

The use of the allocated memory that looks like an array is &p->relocs[0],
but this should be the same as p->relocs.

The semantic patch that makes this change is as follows:
