12 years agoi965: Rewrite the HiZ op
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)

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.

This fixes bug #45082:

mapi/glapi: Never use a generic no-op entry-point on Windows.

When GLAPIENTRY is __stdcall (ie Windows), the stack is popped by the
callee making the number/type of arguments significant, therefore
using a generic no-op causes stack corruption for many entry-points.
