The code for emitting INTEL_swap_events swap completion
events needs to translate from 32-Bit sbc on the wire to
64-Bit sbc for the events and handle wraparound accordingly.
It assumed that events would be sent by the server in the
order their corresponding swap requests were emitted from
the client, iow. sbc count should be always increasing. This
was correct for DRI2.
This is not always the case under the DRI3/Present backend,
where the Present extension can execute presents and send out
completion events in a different order than the submission
order of the present requests, due to client code specifying
targetMSC target vblank counts which are not strictly
monotonically increasing. This confused the wraparound
handling. This patch fixes the problem by handling 32-Bit
wraparound in both directions. As long as successive swap
completion events real 64-Bit sbc's don't differ by more
than 2^30, this should be able to do the right thing.
How this is supposed to work:
awire->sbc contains the low 32-Bits of the true 64-Bit sbc
of the current swap event, transmitted over the wire.
glxDraw->lastEventSbc contains the low 32-Bits of the 64-Bit
sbc of the most recently processed swap event.
glxDraw->eventSbcWrap is a 64-Bit offset which tracks the upper
32-Bits of the current sbc. The final 64-Bit output sbc
aevent->sbc is computed from the sum of awire->sbc and
glxDraw->eventSbcWrap.
Under DRI3/Present, swap completion events can be received
slightly out of order due to non-monotic targetMsc specified
by client code, e.g., present request submission:
Submission sbc: 1 2 3
targetMsc: 10 11 9
Reception of completion events:
Completion sbc: 3 1 2
The completion sequence 3, 1, 2 would confuse the old wraparound
handling made for DRI2 as 1 < 3 --> Assumes a 32-Bit wraparound
has happened when it hasn't.
The client can queue multiple present requests, in the case of
Mesa up to n requests for n-buffered rendering, e.g., n = 2-4 in
the current Mesa GLX DRI3/Present implementation. In the case of
direct Pixmap presents via xcb_present_pixmap() the number n is
limited by the amount of memory available.
We reasonably assume that the number of outstanding requests n is
much less than 2 billion due to memory contraints and common sense.
Therefore while the order of received sbc's can be a bit scrambled,
successive 64-Bit sbc's won't deviate by much, a given sbc may be
a few counts lower or higher than the previous received sbc.
Therefore any large difference between the incoming awire->sbc and
the last recorded glxDraw->lastEventSbc will be due to 32-Bit
wraparound and we need to adapt glxDraw->eventSbcWrap accordingly
to adjust the upper 32-Bits of the sbc.
Two cases, correponding to the two if-statements in the patch:
a) Previous sbc event was below the last 2^32 boundary, in the previous
glxDraw->eventSbcWrap epoch, the new sbc event is in the next 2^32
epoch, therefore the low 32-Bit awire->sbc wrapped around to zero,
or close to zero --> awire->sbc is apparently much lower than the
glxDraw->lastEventSbc recorded for the previous epoch
--> We need to increment glxDraw->eventSbcWrap by 2^32 to adjust
the current epoch to be one higher than the previous one.
--> Case a) also handles the old DRI2 behaviour.
b) Previous sbc event was above closest 2^32 boundary, but now a
late event from the previous 2^32 epoch arrives, with a true sbc
that belongs to the previous 2^32 segment, so the awire->sbc of
this late event has a high count close to 2^32, whereas
glxDraw->lastEventSbc is closer to zero --> awire->sbc is much
greater than glXDraw->lastEventSbc.
--> We need to decrement glxDraw->eventSbcWrap by 2^32 to adjust
the current epoch back to the previous lower epoch of this late
completion event.
We assume such a wraparound to a higher (a) epoch or lower (b)
epoch has happened if awire->sbc and glxDraw->lastEventSbc differ
by more than 2^30 counts, as such a difference can only happen
on wraparound, or if somehow 2^30 present requests would be pending
for a given drawable inside the server, which is rather unlikely.
v2: Explain the reason for this patch and the new wraparound handling
much more extensive in commit message, no code change wrt. initial
version.

If the renderer supports the core profile the query returned incorrectly
0x8 as value, because it was using (1U << __DRI_API_OPENGL_CORE) for the
returned value.
The same happened with the compatibility profile. It returned 0x1
(1U << __DRI_API_OPENGL) instead of 0x2.
Internal DRI defines:
dri_interface.h: #define __DRI_API_OPENGL 0
dri_interface.h: #define __DRI_API_OPENGL_CORE 3
Those two bits are supposed for internal usage only and should be
translated to GLX_CONTEXT_CORE_PROFILE_BIT_ARB (0x1) for a preferred
core context profile and GLX_CONTEXT_COMPATIBILITY_PROFILE_BIT_ARB (0x2)
for a preferred compatibility context profile.
This patch implements the above translation in the glx module.

glXSwapBuffersMscOML() with target_msc=divisor=remainder=0 gets
translated into target_msc=divisor=0 but remainder=1 by the mesa
api. This is done for server DRI2 where there needs to be a way
to tell the server-side DRI2ScheduleSwap implementation if a call
to glXSwapBuffers() or glXSwapBuffersMscOML(dpy,window,0,0,0) was
done. remainder = 1 was (ab)used as a flag to tell the server to
select proper semantic. The DRI3/Present backend ignored this
signalling, treated any target_msc=0 as glXSwapBuffers() request,
and called xcb_present_pixmap with invalid divisor=0, remainder=1
combo. The present extension responded kindly to this with a
BadValue error and dropped the request, but mesa's DRI3/Present
backend doesn't check for error codes. From there on stuff went
downhill quickly for the calling OpenGL client...
This patch fixes the problem.

Prevent calls to glXGetSyncValuesOML() and glXWaitForMscOML()
from overwriting the (ust,msc) values of the last successfull
swapbuffers call (PresentPixmapCompleteNotify event), as
glXWaitForSbcOML() relies on those values corresponding to
the most recent completed swap, not to whatever was last
returned from the server.
Problematic call sequence without this patch would have been, e.g.,
glXSwapBuffers()
... wait ...
swap completes -> PresentPixmapComplete event -> (ust,msc)
updated to reflect swap completion time and count.
... wait for at least 1 video refresh cycle/vblank increment.
glXGetSyncValuesOML()
-> PresentNotifyMsc event overwrites (ust,msc) of swap
completion with (ust,msc) of most recent vblank
glXWaitForSbcOML()
-> Returns sbc of last completed swap but (ust,msc) of last
completed vblank, not of last completed swap.
-> Client is confused.
Do this by tracking a separate set of (ust, msc) for the
dri3_wait_for_msc() call than for the dri3_wait_for_sbc()
call.
This makes the glXWaitForSbcOML() call robust again and restores
consistent behaviour with the DRI2 implementation.
Fixes applications originally written and tested against
DRI2 which also rely on this not regressing under DRI3/Present,
e.g., Neuro-Science software like Psychtoolbox-3.
This patch fixes the problem.
v2: Rename vblank_msc/ust to notify_msc/ust as suggested by

The current implementation of glxUseXFont requires creating
a temporary pixmap and graphics context, which requires a real
old-school X11 Window, not a glxDrawable. This patch changes
things so that glxUseXFont will also accept a glxWindow or
glxPixmap, and lookup the underlying X11 Drawable. Without
this patch glxUseXFont generates a giant stream of Xerrors
about bad drawables and bad graphics contexts.

Instead of just segfaulting in the driver when a buffer allocation fails,
report error messages indicating what went wrong so that we can debug things.
As a simple example, chromium wraps Mesa in a sandbox which doesn't allow
access to most syscalls, including the ability to create shared memory
segments for fences. Before, you'd get a simple segfault in mesa and your 3D
acceleration would fail. Now you get:
$ chromium --disable-gpu-blacklist

A driver which doesn't have async flip support will queue up flips without any
way to replace them afterwards. This means we've got a scanout buffer pinned
as soon as we schedule a flip and so we need another buffer to keep from
stalling.
When vblank_mode=0, if there are only three buffers we do:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting down in the kernel waiting for vblank to
become the next scanout buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
This cannot be displayed at MSC 1 because the
kernel doesn't have any way to replace buffer 1 as the pending
scanout buffer. So, best case this will get displayed at MSC 2.
Now we block after this, waiting for one of the three buffers to become idle.
We can't use buffer 0 because it is the scanout buffer. We can't use buffer 1
because it's sitting in the kernel waiting to become the next scanout buffer
and we can't use buffer 2 because that's the most recent frame which will
become the next scanout buffer if the application doesn't manage to generate
another complete frame by MSC 2.
With four buffers, we get:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting down in the kernel waiting for vblank to
become the next scanout buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
This cannot be displayed at MSC 1 because the
kernel doesn't have any way to replace buffer 1 as the pending
scanout buffer. So, best case this will get displayed at MSC
2. The X server will queue this swap until buffer 1 becomes
the scanout buffer.
Render frame 3 to buffer 3
PresentPixmap for buffer 3 at MSC 1
As soon as the X server sees this, it will replace the pending
buffer 2 swap with this swap and release buffer 2 back to the
application
Render frame 4 to buffer 2
PresentPixmap for buffer 2 at MSC 1
Now we're in a steady state, flipping between buffer 2 and 3
waiting for one of them to be queued to the kernel.
...
current scanout buffer = 1 at MSC 1
Now buffer 0 is free and (e.g.) buffer 2 is queued in
the kernel to be the scanout buffer at MSC 2
Render frames, flipping between buffer 0 and 3
When the system can replace a queued buffer, and we update Present to take
advantage of that, we can use three buffers and get:
current scanout buffer = 0 at MSC 0
Render frame 1 to buffer 1
PresentPixmap for buffer 1 at MSC 1
This is sitting waiting for vblank to become the next scanout
buffer
Render frame 2 to buffer 2
PresentPixmap for buffer 2 at MSC 1
Queue this for display at MSC 1
1. There are three possible results:
1) We're still before MSC 1. Buffer 1 is released,
buffer 2 is queued waiting for MSC 1.
2) We're now after MSC 1. Buffer 0 was released at MSC 1.
Buffer 1 is the current scanout buffer.
a) If the user asked for a tearing update, we swap
scanout from buffer 1 to buffer 2 and release buffer
1.
b) If the user asked for non-tearing update, we
queue buffer 2 for the MSC 2.
In all three cases, we have a buffer released (call it 'n'),
ready to receive the next frame.
Render frame 3 to buffer n
PresentPixmap for buffer n
If we're still before MSC 1, then we'll ask to present at MSC
1. Otherwise, we'll ask to present at MSC 2.
Present already does this if the driver offers async flips, however it does
this by waiting for the right vblank event and sending an async flip right at
that point.
I've hacked the intel driver to offer this, but I get tearing at the top of
the screen. I think this is because flips are always done from within the
ring, and so the latency between the vblank event and the async flip happening
can cause tearing at the top of the screen.
That's why I'm keying the need for the extra buffer on the lack of 2D
driver support for async flips.

The differences with DRI2 GPU offloading are:
a) There's no logic for GPU offloading needed in the Xserver
b) for DRI2, the card would render to a back buffer, and
the content would be copied to the front buffer (the same buffers
everytime). Here we can potentially use several back buffers and copy
to buffers with no tiling to share with X. We send them with the
Present extension.
That means than the DRI2 solution is forced to have tearings with GPU
offloading. In the ideal scenario, this DRI3 solution doesn't have this
problem.
However without dma-buf fences, a race can appear (if the card is slow
and the rendering hasn't finished before the server card reads the buffer),
and then old content is displayed. If a user hits this, he should probably
revert to the DRI2 solution (LIBGL_DRI3_DISABLE). Users with cards fast
enough seem to not hit this in practice (I have an Amd hd 7730m, and I
don't hit this, except if I force a low dpm mode)
c) for non-fullscreen apps, the DRI2 GPU offloading solution requires
compositing. This DRI3 solution doesn't have this requirement. Rendering
to a pixmap also works.
d) There is no need to have a DDX loaded for the secondary card.

This doesn't change anything to the intel DRI3 implementation,
but enables the gallium implementation to use dri2.stamp instead
of relying on the stamp shared with the st backend.

Move the image extension setup in with all the others in
bind_extensions, and improve the check to both version
and function pointer.

While the official INTEL_swap_event specification says that the drawable
field should contain the GLXDrawable, not the Drawable, the existing
DRI2 code in dri2.c that translates from DRI2_BufferSwapComplete sends out
GLX_BufferSwapComplete with the Drawable's ID, so existing codebases
like Clutter/Cogl rely on getting the Drawable.
Match DRI2's error here and stuff the event with the X Drawable, not
the GLX drawable.
This fixes apps seeing wrong drawables through an indirect GLX context
or with DRI3, which uses the GLX_BufferSwapComplete event directly on
the wire instead of translates Present in mesa.
At the same time, also modify the structure for the event to make sure
that clients don't make the same mistake. This is not an API or ABI
break, as GLXDrawable and Drawable are both typedefs for XID.

Prior to GLX 1.3 there was the glxMakeCurrent() function that took a
single drawable handle. The Drawable could be either a bare XID for a
Window or an XID for a glxpixmap.
GLX 1.3 added glxMakeContextCurrent that takes 2 handles: one for
reading, one for writing. Nowadays the old glxMakeCurrent call is
implemented as a call to glxMakeContextCurrent with the single handle
duplicated.
Because of this it is allowed to use a plain-old Window ID as an
argument to glxMakeContextCurrent, although nobody really documents this
sort of thing. The manpage for the NEW call specifies the arguments as
GLXPixmaps, but the actual code accepts Window XIDs too, and handles
them correctly.
Similarly, the glxSelectEvents function can also take a bare Window XID.
The "piglit" tests all use GLXWindows and/or GLXPixmaps. You never
tested swap events with a bare Window XID. That is what my app was
doing.
The swap_events code worked with Window XIDs in mesa 7.x.y. The new code
added in versions 8, 9, and 10 assumes that all buffer swap events have
a GLXPixmap associated with them. Because of the historical quirks
above, this is not true. Swap events for bare Window XIDs do NOT have a
glxpixmap resulting in a segfault.
Any app that uses the old school glxMakeCurrent call with a Window XID
while trying to use swap_events will crash when the libs try to lookup
the nonexistent GLXPixmap associated with the incoming swap event.
I believe that the people who wrote the spec overlooked this, because
the "sbc" field comes from the OML_sync extension that is defined in
terms of glxpixmaps only.

because no matching fbConfigs or visuals could be found.
Nearly all the error cases in *createScreen() issue an error message to diagnose
the failure to initialize before branching to handle_error. The few remaining
error cases which don't should probably do the same.
(At the moment, it seems this can be triggered in drisw with an X server which
reports definite values for MAX_PBUFFFER_(WIDTH|HEIGHT|SIZE), because those
attributes are checked for an exact match against 0.)

The code that parses LIBGL_DRIVERS_PATH was printing an
error for every attempted dlopen. It's not an error to
have to check multiple items in the path, only an error if
no suitable library is found. Reduced the load error to
a warning to match behavior of dynamic linker.

Some untangling to fix building in the dri_platform=none, --enable-driglx-direct
case, where only driswast can be used.
Turn the test for including the glXGetScreenDriver()/glXGetScreenDriver()
interface used by xdriinfo from !GLX_USE_APPLEGL into a positive form, as it is
only useful when dri_platform=drm
Add additional GLX_USE_DRM tests so DRI[123] renderers are only used when
dri_platform=drm
Note that swrast and indirect must still be disabled in the APPLEGL case at the
moment, which makes things more complex than they need to be. More untangling
is needed to allow that
