Revert "drm/ttm: add a way to bo_wait for either the last read or last write"

2011-10-27T16:28:37+00:00

This reverts commit dfadbbdb57b3f2bb33e14f129a43047c6f0caefa.

Further upstream discussion between Marek and Thomas decided this wasn't
fully baked and needed further work, so revert it before it hits mainline.

vmwgfx: information leak in vmw_execbuf_copy_fence_user()

2011-10-18T09:42:01+00:00

If ret is non-zero then we don't initialize the struct which leaks
stack information to user space.

vmwgfx: Add fence events

2011-10-10T14:46:55+00:00

Add a way to send DRM events down the gpu fifo by attaching them to
fence objects. This may be useful for Xserver swapbuffer throttling and
page-flip done notifications.

Bump version to 2.2 to signal the availability of the FENCE_EVENT ioctl.

This function will be used also by the upcoming fence event code,
so break it out and add a comment about the functionality.

vmwgfx: Handle device surface memory limit

2011-10-05T09:17:31+00:00

Make surfaces swappable. Make sure we honor the maximum amount of surface
memory the device accepts. This is done by potentially reading back surface
contents not used by the current command submission and storing it
locally in buffer objects.

vmwgfx: Optimize the command submission resource list

2011-10-05T09:17:23+00:00

Use a list for resources referenced during command submission, instead of
an array.
As long as we don't implement parallell command submission this works fine
and simplifies things a bit.

vmwgfx: Fix up query processing

2011-10-05T09:17:22+00:00

Previously, query results could be placed in any buffer object, but since
we didn't allow pinned buffer objects, query results could be written when
that buffer was evicted, corrupting data in other buffers.

Now, require that buffers holding query results are no more than two pages
large, and allow one single pinned such buffer. When the command submission
code encounters query result structures in other buffers, the queries in the
pinned buffer will be finished using a query barrier for the last hardware
context using the buffer. Also if the command submission code detects
that a new hardware context is used for queries, all queries of the previous
hardware context is also flushed. Currently we use waiting for a no-op
occlusion query as a query barrier for a specific context.

The query buffer is also flushed and unpinned on context destructions,
master drops and before scanout bo placement.
