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.

(cherry picked from commit 4aa128a123)
A drawable size of 0x0 means that we don't have buffers for a drawable yet,
not that we have a zero-sized buffer. Core mesa shouldn't be optimizing out
drawing based on buffer size, since the draw call could be what triggers
the driver to go and get buffers. As discussed in the referenced bug report,
the optimization was added as part of a scatter-shot attempt to fix a
different problem. There's no other example in mesa core of using the
buffer size in this way.

When a multisampled texture is used for sampling the fast clear color value
needs to be programmed into the surface state. This was being left as all
zeroes so if the surface was cleared to a value other than black then it
wouldn't work properly. This doesn't matter for single-sample textures because
in that case the MCS buffer is resolved before it is used as a texture source.

Ideally we wouldn't munge the incoming state, so that we wouldn't need
to unmunge it back on glGet*. But the array size state is copied and
referred in many places, many of which couldn't take an GLenum like
GL_BGRA instead of a plain integer. So just hack around on glGet*,
to ensure there is no risk of introducing regressions elsewhere.

(cherry picked from commit eb2241f8a9)
The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy. This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context. The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.
But ARB_robustness spec says:
If a reset status other than NO_ERROR is returned and subsequent calls
return NO_ERROR, the context reset was encountered and completed. If a
reset status is repeatedly returned, the context may be in the process
of resetting.
8. How should the application react to a reset context event?
RESOLVED: For this extension, the application is expected to query the
reset status until NO_ERROR is returned. If a reset is encountered, at
least one *RESET* status will be returned. Once NO_ERROR is
encountered, the application can safely destroy the old context and
create a new one.
The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned. But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed. For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.
The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context. Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.

Retrieving the high 32 bits of a signed multiply is rather annoying. It
appears that the simplest way to do this is to compute the absolute
value of the arguments, and perform a u32 x u32 -> u64 operation. If the
arguments' signs differ, then negate the result. Since there is no u64
support in the cvt instruction, we have the perform the 2's complement
negation "by hand".
This logic can come into use by the IMUL_HI instruction (very unlikely
to be seen), as well as from constant folding of division by a constant.

We allocate dispatch tables for BeginEnd and OutsideBeginEnd. But
when we destroy the context we were freeing the BeginEnd and Exec
tables. If Exec==BeginEnd we did a double-free. This would happen
if the context was destroyed while inside a glBegin/End pair. Now
free the BeginEnd and OutsideBeginEnd pointers.
