The GLX specification says about glXDestroyPixmap:
"The storage for the GLX pixmap will be freed when it is not current
to any client."
So arguably, functions like glXSwapIntervalMESA can be called after
glXDestroyPixmap has been called for the currently bound GLXPixmap.
In that case, the GLXDRIDrawable no longer exists, and so we just skip
those calls.

Commit cf804b4455
('glx: fix crash with bad fbconfig') introduced a check
in glXCreateNewContext() if the given config is a valid
fbconfig.
Unfortunately the check always checks the given config against
the fbconfigs of the DefaultScreen(dpy), instead of the
actual X-Screen specified in the config config->screen.
This leads to failure whenever a GL context is created
on a non-DefaultScreen(dpy), e.g., on X-Screen 1 of
a multi-x-screen setup, where the default screen is
typically 0.
Fix this by using config->screen instead of DefaultScreen(dpy).
Tested to fix context creation failure on a dual-x-screen setup.

Structurally, this is very similar to the existing Apple-DRI code, except I
have chosen to implement this using the __GLXDRIdisplay, etc. vtables (as

This adds:
* the Windows-DRI extension protocol headers and the windowsdriproto.pc
file, for use in building the Windows-DRI extension for the X server
* a Windows-DRI extension helper client library
* a Windows-specific DRI implementation for GLX clients
The server is queried for Windows-DRI extension support on the screen before
using it (to detect the case where WGL is disabled or can't be activated).
The server is queried for fbconfigID to pixelformatindex mapping, which is
used to augment glx_config.
The server is queried for a native handle for the drawable (which is of a
different type for windows, pixmaps and pbuffers), which is used to augment
__GLXDRIdrawable.
Various GLX extensions are enabled depending on if the equivalent WGL
extension is available.
Currently, due to the inverse order, strcmp will produce negative result
when the needle is towards the start of the haystack. Thus on the next
iteration(s) we'll end up further towards the end and eventually fail to
locate the entry.

There is no draw arrays protocol support for multi-texture coordinate
arrays, so it is implemented by sending batches of immediate mode
commands from emit_element_none in indirect_vertex_array.c. This sends
the target texture unit (which has been previously setup in the
array_state header field), followed by the texture coordinates. But for
GL_DOUBLE coordinates the texture unit must be sent *after* the texture
coordinates. This is documented in the glx protocol description, and can
also be seen in the indirect.c immediate mode commands generated from
gl_API.xml. Sending the target texture unit in the wrong place can crash
the remote X server.
To fix this required some more extensive changes to
indirect_vertex_array.c and indirect_vertex_array_priv.h, in order to
remove the texture unit value out of the array_state "header" field, and
send it separately.

For each indirect context the indirect vertex array state must be initialised
by __glXInitVertexArrayState in indirect_vertex_array.c. As noted in the
routine header it requires that the glx context has been setup prior to the
call, in order to test the server version and extensions.
Currently __glXInitVertexArrayState is called from indirect_bind_context in
indirect_glx.c, as follows:
state = gc->client_state_private;
if (state->array_state == NULL) {
glGetString(GL_EXTENSIONS);
glGetString(GL_VERSION);
__glXInitVertexArrayState(gc);
}
But, the gc context is not yet usable at this stage, so the server queries
fail, and __glXInitVertexArrayState is called without the server version and
extension information it needs. This breaks multi-texturing as
glXInitVertexArrayState doesn't get GL_MAX_TEXTURE_UNITS. It probably also
breaks setup of other arrays: fog, secondary colour, vertex attributes.
To fix this I have moved the call to __glXInitVertexArrayState to the end of
MakeContextCurrent in glxcurrent.c, where the glx context is usable.
Fixes a regression caused by commit 4fbdde889c. Fixes ARB_vertex_program

was pretty broken.
The legacy swrast driver tracks when a front buffer is used
and does the get/put images when it is mapped/unmapped,
so this patch attempts to add the same functionality to the
gallium drivers.
It creates a new context interface to denote when a front
buffer is being created, and passes a private pointer to it,
this pointer is then used to decide on map/unmap if the
contents should be updated from the real frontbuffer using
get/put image.

In the DRI2 path this event is magically synthesized from the
corresponding DRI2 event, but with Present, the server sends us the
event itself. The DRI2 path fills in the serial number, send_event, and
display fields of the XEvent struct that the app sees, but the Present
path did not.
This is likely related to a class of crashes seen in gtk/clutter apps:
https://bugzilla.redhat.com/attachment.cgi?id=1032631
Note that the crashing instruction is looking up the lock_fns slot in
the Display *, and %rdi (holding the Display *) is 0x1.

Previously GLX_EXT_create_context_es2_profile was marked as "direct
only" so that it would not depend on server support. Since the
extension required functions that are part of
GLX_ARB_create_context_profile, support for the EXT was disabled if the
ARB was not supported.
This was complete rubbish. If the server supported the ARB but not the
EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result
in GLXBadProfileARB.
Instead of the misguided hack, make GLX_EXT_create_context_es2_profile

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.

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.

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.

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

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

Define GLX_USE_APPLEGL, as config/darwin used to, to turn on specific code to
use the applegl direct renderer
Convert src/glx/apple/Makefile to automake
Since the applegl libGL is now built by linking libappleglx into libGL, rather
than by linking selected files into a special libGL:
- Remove duplicate code in apple/glxreply.c and apple/apple_glx.c. This makes
apple/glxreply.c empty, so remove it
- Some indirect rendering code is already guarded by !GLX_USE_APPLEGL, but we
need to add those guards to indirect_glx.c, indirect_init.c (via it's
generator), render2.c and vertarr.c so they don't generate anything
Fix and update various includes
glapi_gentable.c (which is only used on darwin), should be included in shared
glapi as well, to provide _glapi_create_table_from_handle()
Note that neither swrast nor indirect is supported in the APPLEGL path at the
moment, which makes things more complex than they need to be. More untangling
is needed to allow that

- Don't require xcb-dri[23] etc. if we aren't building for a target with DRM, as
we won't be using dri[23]
- Enable a more fine-grained control of what DRI code is built, so that a libGL
using direct swrast can be built on targets which don't have DRM.
The HAVE_DRI automake conditional is retired in favour of a number of other
conditionals:
HAVE_DRI2 enables building of code using the DRI2 interface (and possibly DRI3
with HAVE_DRI3)
HAVE_DRISW enables building of DRI swrast
HAVE_DRICOMMON enables building of target-independent DRI code, and also enables
some makefile cases where a more detailled decision is made at a lower level.
HAVE_APPLEDRI enables building of an Apple-specific direct rendering interface,
still which requires additional fixing up to build properly.

Fix build for darwin, when ./configured --disable-driglx-direct
- darwin ld doesn't support -Bsymbolic or --version-script, so check if ld
supports those options before using them
- define GLX_ALIAS_UNSUPPORTED as config/darwin used to, as aliasing of non-weak
symbols isn't supported
- default to -with-dri-drivers=swrast
v2:
Use -Wl,-Bsymbolic, as before, not -Bsymbolic
Test that ld --version-script works, rather than just looking for it in ld --help
Don't use -Wl,--no-undefined on darwin, either

This should have happend around the time of commit 4680d23, but Keith's
DRI3 patches and my GLX_MESA_query_renderer patches crossed in the mail.
I don't have a working DRI3 setup, so I haven't been able to actually
verify this. I'm hoping that someone can piglit this for me on DRI3...
It's also unfortunate the DRI2 and DRI3 can't share more code.
