Jon Turney d3540b405b glx/apple: locate dispatch table functions to wrap by name
Avoid reaching into the dispatch table internals (and thus having to deal
with the complexities of remap etc.) by identifying functions to wrap by
name.

See:
https://lists.freedesktop.org/archives/mesa-dev/2015-June/086721.html et seq.

Samuel Thibault 47ac11bcf8 glx: fix non-dri build
glXGetDriverConfig parameters do not provide a context to dynamically
check for the presence of the function, so the dispatcher directly calls
glXGetDriverConfig, but in non-dri builds dri_glx.c didn't provide
glXGetDriverConfig.

This change make it just return NULL in that case.

This `version` field defines the filename for the .so.
The plan .so as well as .so.$major are always symlinks to this.

Unless I'm mistaken, only the major is ever used, so this shouldn't
matter, but for consistency with autotools (and in case it does matter),
let's always have all 3 major.minor.patch components.

(The soname isn't affected, and is always .so.$major)

Dylan Baker 108d257a16 meson: build libEGL
This is based heavily on Daniel Stone's work for the same, rebased on
master and with a number of TODO's fixed.

This does not implement glvnd (which is coming in a later patch)

Meson builds egl slightly differently than autotools, namely it doesn't
build an intermediate shared library. It doesn't do this because meson
doesn't have problems with the name of the library being dynamically
generated, so the glvnd and non-glvnd code can follow the same path.

Thomas Hellstrom 2db9548296 loader_dri3/glx/egl: Optionally use a blit context for blitting operations
The code was relying on us always having a current context for client local
image blit operations. Otherwise the blit would be skipped. However,
glxSwapBuffers, for example, doesn't require a current context and that was a
common problem in the dri1 era. It seems the problem has resurfaced with dri3.

If we don't have a current context when we want to blit, try creating a private
dri context and maintain a context cache of a single context.

Emil Velikov 10e7c2c64d loader: rework xmlconfig dependency
Currently xmlconfig is conditionally used, only when --enable-dri is
available.

As the library has moved to src/util and has wider wisebase, this guard
is no longer correct. Strictly speaking - it wasn't since the
introduction of xmlconfig into st/nine a while ago.

Unconditionally enable xmlconfig and drop the linking. As said before
there's other users of the library, so depending on the configure
options we will get multiple definitions of said symbols.

NOTE: To avoid breaking other combinations, this commit adds the
xmlconfig link to the required places - throughout gallium and the DRI
loaders.

With GLX_EXT_buffer_age turned on, gnome-shell will use full-screen damage

Thomas Hellstrom 1253d58983 dri3/GLX: Fix drawable invalidation v2
A number of internal VMware apitrace traces image comparisons fail with

until the second draw-call after a swapBuffer.

Comparing with the dri2 glx code there are a couple of places where dri2

where dri3 doesn't do that. When these invalidation points are added to
dri3, the image comparisons become correct.

Hans de Goede 84f764a759 glxglvnddispatch: Add missing dispatch for GetDriverConfig
Together with some fixes to xdriinfo this fixes xdriinfo not working
with glvnd.

Since apps (xdriinfo) expect GetDriverConfig to work without going to
need through the dance to setup a glxcontext (which is a reasonable
expectation IMHO), the dispatch for this ends up significantly different
then any other dispatch function.

This patch gets the job done, but I'm not really happy with how this
patch turned out, suggestions for a better fix are welcome.

Hans de Goede 4c66f529a8 glx/glvnd: Fix GLXdispatchIndex sorting
Commit 8bca8d89ef ("glx/glvnd: Fix dispatch function names and indices")
fixed the sorting of the array initializers in g_glxglvnddispatchfuncs.c
because FindGLXFunction's binary search needs these to be sorted
alphabetically.

That commit also mostly fixed the sorting of the DI_foo defines in
g_glxglvnddispatchindices.h, which is what actually matters as the
arrays are initialized using "[DI_foo] = glXfoo," but a small error
crept in which at least causes glXGetVisualFromFBConfigSGIX to not
resolve, breaking games such as "The Binding of Isaac: Rebirth" and
"Crypt of the NecroDancer" from Steam not working and possible causes
other problems too.

This commit fixes the last of the sorting errors, fixing these mentioned
games not working.

The GLX specification says about glXDestroyPixmap:

    "The storage for the GLX pixmap will be freed when it is not current

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.

Mario Kleiner 0c94ed0987 glx: Perform check for valid fbconfig against proper X-Screen.
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.

The function deals with fb (style) configs, thus using "visual"

Jon Turney 533b3530c1 direct-to-native-GL for GLX clients on Cygwin ("Windows-DRI")
Structurally, this is very similar to the existing Apple-DRI code, except I
have chosen to implement this using the __GLXDRIdisplay, etc. vtables (as
suggested originally in [1]), rather than a maze of ifdefs.  This also means
that LIBGL_ALWAYS_SOFTWARE and LIBGL_ALWAYS_INDIRECT work as expected.

[1] https://lists.freedesktop.org/archives/mesa-dev/2010-May/000756.html

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.

That untested commit broke the tex-skipped-unit piglit test and the

state->array_state is used during initialization, so its assignment cannot be
moved to the end of the function.

The backtrace looked like:

Colin McDonald b36644bae6 glx: Fix indirect multi-texture GL_DOUBLE coordinate arrays.
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.

Colin McDonald d57c85c1bf glx: Call __glXInitVertexArrayState() with a usable gc.
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
usage in the arbvparray Mesa demo when run with indirect GLX and also
the tex-skipped-unit piglit test when run with indirect GLX.

Dave Airlie 2b67657096 gallium/swrast: fix front buffer blitting. (v2)
So I've known this was broken before, cogl has a workaround
for it from what I know, but with the gallium based swrast
drivers BlitFramebuffer from back to front or vice-versa
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.

This is primarily to make gtk's gl code work, the only
thing I've tested so far is the glarea test from
https://github.com/ebassi/glarea-example.git

v2: bump extension version,
check extension version before calling get image. (Ian)

Adam Jackson 8f7ebcb6fa glx: Fix __glXWireToEvent for BufferSwapComplete
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

Ian Romanick 8957c9e448 glx: Create proper server dependency for GLX_EXT_create_context_es2_profile
Previously GLX_EXT_create_context_es2_profile was marked as "direct

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
properly depend on server support by not marking it as "direct only."

Mario Kleiner cc5ddd584d glx: Handle out-of-sequence swap completion events correctly. (v2)
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

The same happened with the compatibility profile. It returned 0x1

Internal DRI defines:

Those two bits are supposed for internal usage only and should be

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.

Mario Kleiner ad8b0e8bf6 glx/dri3: Track separate (ust, msc) for PresentPixmap vs. PresentNotifyMsc (v2)
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
Axel Davy for better clarity.

Mario Kleiner 8cab54de16 glx/dri3: Fix glXWaitForSbcOML() to handle targetSBC==0 correctly. (v2)
targetSBC == 0 is a special case, which asks the function
to block until all pending OpenGL bufferswap requests have
completed.

Currently the function just falls through for targetSBC == 0,
returning bogus results.

This breaks 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: Simplify as suggested by Axel Davy. Add comments proposed
by Eric Anholt.

things so that glxUseXFont will also accept a glxWindow or
glxPixmap, and lookup the underlying X11 Drawable. Without

Keith Packard 3202926746 glx/dri3: Provide error diagnostics when DRI3 allocation fails
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:

Keith Packard f7a355556e glx/dri3: Use four buffers until X driver supports async flips
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.
