* swrast: fix left side clippingBrian Paul2010-02-181-3/+36
| | | | | | | Fixes bug 26623. Original patch was submitted by Mathias Frohlich and modified by Brian. (cherry picked from commit 7c34c237a2f6732b2c013543523617e375c1f534)
* Revert "st/mesa: Make the frontbuffer visible on st_flush(PIPE_FLUSH_FRAME)."Francisco Jerez2010-02-181-4/+8
| | | | | | We probably don't want to propagate this condition to the pipe driver, this reverts commit f455ca6490fcb65781b21f81c7117bd923e250d1 and the dri_update_buffer flush altogether until an agreement is reached.
* intel: Include main/hash.h using "" instead of <>Kristian Høgsberg2010-02-181-1/+1

* st/mesa: always call FLUSH_CURRENT before st->pipe->flush()Keith Whitwell2010-02-181-2/+1
| | | | | | Undoes part of commit f455ca6 which would permit pipe->flush() to be called while the VBO module still had its buffers mapped. Some drivers care deeply about this. Sorry for not spotting this earlier.
* intel: Implement the DRI2 invalidate function properlyKristian Høgsberg2010-02-1716-48/+79
| | | | | | | | | | | | | | | | | | | This uses a stamp mechanisms to mark the DRI drawable as invalid. Instead of immediately updating the buffers we just bump the drawable stamp and call out to DRI2GetBuffers "later". "Later" used to be at LOCK_HARDWARE time, and this patch brings back callouts at the points where we used to call LOCK_HARDWARE. A new function, intel_prepare_render(), is called where we used to call LOCK_HARDWARE, and if the buffers are invalid, we call out to DRI2GetBuffers there. This lets us invalidate buffers only when notified instead of on every glViewport() call. If the loader calls the DRI invalidate entrypoint, we disable viewport triggered buffer invalidation. Additionally, we can clean up the old viewport mechanism a bit, since we can just invalidate the buffers and not worry about reentrancy and whatnot.

* st/mesa: Make the frontbuffer visible on st_flush(PIPE_FLUSH_FRAME).Francisco Jerez2010-02-171-9/+6
| | | | | | | | | | | | | So far the frontbuffer was only being flushed on st_glFlush and st_glFinish, however, a co-state tracker may need to make sure that any frontbuffer changes are already on its way to the actual front. The dri2 state tracker will need this for event-driven GL applications to resize properly (It could also be done calling "dri_flush_frontbuffer", but that way we would flush unnecessarily in the double-buffered case). Additionally this patch avoids flushing the mesa rendering cache if PIPE_FLUSH_RENDER_CACHE wasn't specified.

* dri2: Event driven buffer validation.Francisco Jerez2010-02-165-12/+20
| | | | | | | | | | | | | | | | | | When a buffer invalidation event is received from the X server, the "invalidate" hook of the DRI2 flush extension is executed: A generic implementation (dri2InvalidateDrawable) is provided that just bumps the "pStamp" sequence number in __DRIdrawableRec. For old servers not supporting buffer invalidation events, the invalidate hook will be called before flushing the fake front/back buffer (that's typically once per frame -- not a lot worse than the situation we were in before). No effort has been made on preserving backwards compatibility with version 2 of the flush extension, but I think it's acceptable because AFAIK no released stack is making use of it.

| | | | | | | | | __builtin_clz with parameter 0 has undefined value. When using -O3 optimizing this would result to too large next power of two value. Fix is to check if passed value is 1 and modify formula for that case.

* mesa: enable GL_ARB_fragment_coord_conventions for sw driversBrian Paul2010-02-131-2/+2
| | | | | This extension is now implemented in the GLSL compiler so it can be enabled by other drivers where applicable.
* glsl: implement layout qualifiersBrian Paul2010-02-131-19/+110
| | | | | | | | | | | | | For GL_ARB_fragment_coord_conventions. This only applies to gl_FragCoord and controls pixel center origin and pixel center integer. For example: layout (origin_upper_left, pixel_center_integer) varying vec4 gl_FragCoord; This features introduces the idea of re-declaring variables with a changed type. This may also apply to arrays in some cases but that's not implemented at this time.

* st/mesa: improved draw_range_elements codeBrian Paul2010-02-121-9/+7
| | | | | | | | Don't use pipe->draw_range_elements() if min_index=max_index=~0 since that doesn't provide any useful info. Also, implement the loop around pipe->draw_range_elements() when nr_prims > 1.
