Avoid unrollong loops that are either nested loops or
where the loop body times the unroll count is huge.
The change is far from being perfect but it extends the

a shader precomputing atmospheric scattering integral
tables containing two nesting levels in a loop from
something way beyond some minutes (I never waited for

Chad Versace [Thu, 26 Jan 2012 19:01:36 +0000 (11:01 -0800)]
i965: Rewrite the HiZ op
The HiZ op was implemented as a meta-op. This patch reimplements it by
emitting a special HiZ batch. This fixes several known bugs, and likely
a lot of undiscovered ones too.
==== Why the HiZ meta-op needed to die ====
The HiZ op was implemented as a meta-op, which caused lots of trouble. All
other meta-ops occur as a result of some GL call (for example, glClear and
glGenerateMipmap), but the HiZ meta-op was special. It was called in
places that Mesa (in particular, the vbo and swrast modules) did not
expect---and were not prepared for---state changes to occur (for example:
glDraw; glCallList; within glBegin/End blocks; and within
swrast_prepare_render as a result of intel_miptree_map).
In an attempt to work around these unexpected state changes, I added two
hooks in i965:
- A hook for glDraw, located in brw_predraw_resolve_buffers (which is
called in the glDraw path). This hook detected if a predraw resolve
meta-op had occurred, and would hackishly repropagate some GL state
if necessary. This ensured that the meta-op state changes would not
intefere with the vbo module's subsequent execution of glDraw.
- A hook for glBegin, implemented by brwPrepareExecBegin. This hook
resolved all buffers before entering
a glBegin/End block, thus preventing an infinitely recurring call to
vbo_exec_FlushVertices. The vbo module calls vbo_exec_FlushVertices to
flush its vertex queue in response to GL state changes.
Unfortunately, these hooks were not sufficient. The meta-op state changes
still interacted badly with glPopAttrib (as discovered in bug 44927) and
with swrast rendering (as discovered by debugging gen6's swrast fallback
for glBitmap). I expect there are more undiscovered bugs. Rather than play
whack-a-mole in a minefield, the sane approach is to replace the HiZ
meta-op with something safer.
==== How it was killed ====
This patch consists of several logical components:
1. Rewrite the HiZ op by replacing function gen6_resolve_slice with
gen6_hiz_exec and gen7_hiz_exec. The new functions do not call
a meta-op, but instead manually construct and emit a batch to "draw"
the HiZ op's rectangle primitive. The new functions alter no GL
state.
2. Add fields to brw_context::hiz for the new HiZ op.
3. Emit a workaround flush when toggling 3DSTATE_VS.VsFunctionEnable.
4. Kill all dead HiZ code:
- the function gen6_resolve_slice
- the dirty flag BRW_NEW_HIZ
- the dead fields in brw_context::hiz
- the state packet manipulation triggered by the now removed
brw_context::hiz::op
- the meta-op workaround in brw_predraw_resolve_buffers (discussed
above)
- the meta-op workaround brwPrepareExecBegin (discussed above)

intel: FBOs with texture border are unsupported
FBOs differ from textures in a significant way. With textures, we can
strip the border and get correct rendering except when the application
fetches texels outside [0,1].
With an FBO, the pixel at (0,0) is in the border. The
ARB_framebuffer_object spec says:
"If the attached image is a texture image, then the window
coordinates (x[w], y[w]) correspond to the texel (i, j, k), from
figure 3.10 as follows:
i = (x[w] - b)
j = (y[w] - b)
k = (layer - b)
where <b> is the texture image's border width..."
Since the border doesn't exist, we can never render any pixels in the
correct location. Just mark these FBOs FRAMEBUFFER_UNSUPPORTED.

gallium/dri: Handle xserver that doesn't send needless DRI2 invalidate events
Ever since xserver commit
531869448d07e00ae241120b59f3aaaa5709d59c,
the server no longer sends invalidate events to clients, unless they
have performed a GetBuffers request since the drawable was last
invalidated.
If the drawable gets invalidated immediately after the GetBuffers
request was processed by the X server, it's possible that Xlib
will process the invalidate event while waiting for the GetBuffers
reply. So the server, thinking the client knows that the buffers
are invalid, is waiting for another GetBuffers request before
sending any more invalidate events. The client, on the other hand,
believes the buffers to be valid, and thus is expecting to receive
another invalidate event before it has to send another GetBuffers
request. The end result is that the client never again sends
a GetBuffers request.
To avoid this problem, take a snapshot of the lastStamp before
doing GetBuffers, and retry if the snapshot and the current
lastStamp no longer match after the GetBuffers reply has been
processed.

glsl: Avoid ralloc_stealing a long-lived object to a short-lived parent
In commit
6ecee54a9aecc120cb68b02f7e14dcac86b9eca2 a call to
talloc_reference was replaced with a call to talloc_steal. This was in
preparation for moving to ralloc which doesn't support reference
counting.
The justification for talloc_steal within token_list_append in that
commit is that the tokens are being copied already. But the copies are
shallow, so this does not work.
Fortunately, the lifetime of these tokens is easy to understand. A
token list for "replacements" is created and stored in a hash table
when a function-like macro is defined. This list will live until the
macro is #undefed (if ever).
Meanwhile, a shallow copy of the list is created when the macro is
used and the list expanded. This copy is short-lived, so is unsuitable
as a new parent.
So we can just let the original, longer-lived owner continue to own
the underlying objects and things will work.
