62fcd364ac dri2: Set vdpau driver name if ddx does not provide any driver name
Currently when the ddx does not set any driver name we set DRI2 driver but
not the VDPAU driver name. The result is that VDPAU drivers will not get found
by libvdpau when the modesetting driver is being used.

Just assume that the VDPAU driver matches the DRI2 driver name, this is true
for nouveau, r300, r600 and radeonsi i.e all VDPAU drivers currently supported
by mesa.

when iterating the list of offload_source Screens to find a matching

34a98c8103 dri2: Automatically fill in the driver name if the DDX doesn't provide it.
This will be used by the modesetting driver to support DRI2 across all
hardware that can support glamor, and could potentially be used by
other drivers that have to support DRI2 on sets of hardware with
multiple Mesa drivers.

This logic is the same as what's present in the Mesa driver loader,
except for the lack of nouveau_vieux support (which requires a
predicate on the device).

470d97e1d1 dri2: Import a copy of Mesa's PCI ID -> driver name mappings.
This comes from Mesa commit acdcef6788beaa2a1532e13ff84c3e246b8025ed

Previously, each driver had to tell DRI2 what GL driver object should
be loaded.  Originally for a 2D driver that was a matter of giving the
constant string for the vendor name, same as the driver's name.  For a
driver that's trying to handle multiple generations of hardware with
different Mesa driver filenames, the driver had to bake in a mapping
from PCI ID to the appropriate driver name in Mesa, which seems like a
pretty awful layering violation (and one that was fixed with DRI3)

As of January, Mesa now handles the mapping from a DRI fd to the
driver name on its own, but the AIGLX loader still relies on DRI2 for
choosing the filename.  Instead of propagating the PCI ID list from
each 2D driver to the modesetting driver, import a central copy of the
PCI ID list so that drivers can stop handling this themselves.  (Some
day, when AIGLX transitions to EGL, we can drop the DRI2 filename
setup entirely).

138bf5ac97 DRI2SwapBuffers: Fix uninitialized target SBC.
Fixes Piglit test "swapbuffersmsc-return swap_interval 0".

Ensure that *swap_target gets initialized on any 'return Success' path,
even if the swap request can't be completed by the driver and the server
falls back to a simple blit. That path can also be triggered by setting
swap_interval to 0, which disables sync to vertical retrace.

We originally found this bug because for some reason SDL2 automatically
sets swap_interval to 0, when we were trying to test OML_sync_control in
an SDL2 test application. We then discovered that the above-mentioned
Piglit test has been failing for the same reason since it was
introduced.

4927af4475 DRI2SwapBuffers: Don't reuse swap_target variable.
swap_target is an out-parameter that needs to be set to the value that
SBC will take on after this SwapBuffers request completes.

However, it was also being used as a temporary variable to hold the MSC
at which the SwapBuffers request got scheduled to occur. This confusion
makes it harder to reason about whether swap_target is being set
correctly for its out-parameter usage. (Hint: It isn't.)

For the latter use, it makes more sense to use the existing target_msc
variable, which already has the right value unless target_msc, divisor,
and remainder are all 0, in which case we can set it using swap_interval
as usual.

77e51d5bbb Revert "DRI2: re-allocate DRI2 drawable if pixmap serial changes"
This reverts commit 3209b094a3.  After a
long debug session by Paul Berry, it appears that this was the commit
that has been producing sporadic failures in piglit front buffer
rendering tests for the last several years.

GetBuffers may return fresh buffers with invalid contents at a couple
reasonable times:

- When first asked for a non-fake-front buffer.
- When the drawable size is changed, an Invalidate has been sent, and
  obviously the app needs to redraw the whole buffer.
- After a glXSwapBuffers(), GL allows the backbuffer to be undefined,
  and an Invalidate was sent to tell the GL that it should grab these
  appropriate new buffers to avoid stalling.

But with the patch being reverted, GetBuffers would also return fresh
invalid buffers when the drawable serial number changed, which is
approximately "whenever, for any reason".  The app is not expecting
invalid buffer contents "whenever", nor is it valid.  Because the GL
usually only GetBuffers after an Invalidate is sent, and the new
buffer allocation only happened during a GetBuffers, most apps saw no
problems.  But apps that do (fake-)frontbuffer rendering do frequently
ask the server for the front buffer (since we drop the fake front
allocation when we're not doing front buffer rendering), and if the
drawable serial got bumped midway through a draw, the server would
pointlessly ditch the front *and* backbuffer full of important
drawing, resulting in bad rendering.

The patch was originally to fix bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=28365
Specifically:

    To reproduce, start with a large-ish display (i.e. 1680x1050 on my
    laptop), use the patched glxgears from bug 28252 to add the
    -override option.  Then run glxgears -override -geometry 640x480
    to create a 640x480 window in the top left corner, which will work
    fine.  Next, run xrandr -s 640x480 and watch the fireworks.

I've tested with an override-redirect glxgears, both with vblank sync
enabled and disabled, both with gnome-shell and no window manager at
all, before and after this patch.  The only problem observed was that
before and after the revert, sometimes when alt-tabbing to kill my
gears after completing the test gnome-shell would get confused about
override-redirectness of the glxgears window (according to a log
message) and apparently not bother doing any further compositing.

3029801216 dri2: add initial prime support. (v1.2)
This adds the initial prime support for dri2 offload. The main thing is
when we get a connection from a prime client, we stored the information
and mark all drawables from that client as prime. We then create all
buffers for that drawable on the prime device dri2screen.

Then DRI2UpdatePrime is provided which drivers can call to get a shared
pixmap which they can use as the front buffer. The driver is then
responsible for doing the back->front copy to the shared buffer.

prime requires a compositing manager be run, but it handles the case where
a window get un-redirected by allocating a new pixmap and pointing the crtc
at it while the client is in that state.

Currently prime can't handle pageflipping, so always does straight copy swap,

v1.2: fix auth on top of master.

e8fd23fad0 dri2: Invalidate DRI2 buffers for all windows with the same pixmap on swap
Without this, when a compositing manager unredirects a fullscreen window which
uses DRI2 and page flipping, the DRI2 buffer information for the compositing
manager's output window (typically the Composite Overlay Window or root window)
may become stale, resulting in all kinds of hilarity.

6f916ffec7 dri2: Always re-generate front buffer information when asked for it.
Otherwise we might keep stale cached information, e.g. after the driver
performed page flipping.

603fcb3abf dri2: Initialize needInvalidate member of DRI2Drawable.
If the client is not behaving correctly and swaps buffers before
getting them, Valgrind will complain about uninitialized memory being
used in DRI2InvalidateDrawable.

34b0e4eee9 dri2: Register the DRI2DrawableType after server regeneration
The Resource database is reset upon regeneration and so the dri2 module
needs to re-register its RESTYPE for the drawable or else it will
clobber the next unsuspecting user of the database. Fortunately, DRI2 is
loaded late in the initialisation sequence and was last up until
xf86-video-intel started using the Resource database to track
outstanding swaps...

b435e2aac1 DRI2: Expose API to set drawable swap limit.
This allows ddx to set swap_limit if there is more than one back
buffer for drawable. Setting swap_limit has to also check if change
affects a client that is blocked.

This can be used to implement N-buffering in driver with minimal
logic in allocation and selecting next back.

86f8da0aa7 DRI2: Add ReuseBufferNotify hook
ReuseBufferNotify hook is called whenever old buffer is reused in DRI2
code.

Driver can use this hook to rewrite the buffer name if hardware requires
shared buffers. Shared buffer might be some hardware limited resources like
framebuffer that is preallocated in boot.
