Now that intel_flush() deosn't use the needs_mi_flush argument, we can
finally drop one of the two flush functions.
|
|
Without this patch, any old intel_flush() call will cause a round trip to
the server and do a copy from fake to real front. We only actually
guarantee that frontbuffer results show up when glFlush() ia called, so
move the flushing to intel_glFlush().
We also need to flush fake to front before getting new buffers, but
we just handle that manually.
|
|
When we call intel_prepare_render() from intelReadPixels(), we'll mark
the front buffer dirty. That's silly, since we're only reading from it
and marking it dirty will cause us to copy from fake front to front
eventually.
Just clear the dirty flag after doing the read.
|
|
Now that we have intel_prepare_render() in place, we can use it to mark
the front buffer dirty if we're rendering to the front buffer once we
get there.

This is actually better than a real implementation, which would be useless
due to inaccuracy (I know because I've tried to implement it).

Move glapi to src/mapi/{glapi,es1api,es2api}.
|
|
This prevents memory usage explosion in blender due to the state cache
hanging on to old fake frontbuffer regions. Sigh at blender still
using frontbuffer rendering.
Bug #24119.

Noted on the mailing list for an app that puts each glyph for its text
into a separate texture.

Even though swrast defines its own __DriverAPIRec it still shares the
driCreateNewContext() implementation from dri_util.c. So the CreateContext
prototypes have to match in the two __DriverAPIRecs.

Rename old IGDNG to Ironlake, and set 'gen' number for
Ironlake as 5, so tracking the features with generation num
instead of special is_ironlake flag.

Most of the failure from using uninlined function calls ends up being
just bad rendering, but nested function calls in the VS currently hang
the GPU, so reject them and explain why.

We were doubling up the offsets for the mipmap levels for CPU access.
Instead of reimplementing i945_miptree_layout_2d with 6 cube images
separated by qpitch, share that function and provide the level offsets
later.
Fixes piglit cubemap and fbo-cubemap.

This should be functionally equivalent, with the possible exception of
NaN handling.

We could use this to reduce constant register pressure, but for now it
makes the resulting program assembly much more readable.

Fixes hang with "gst-launch-0.10 videotestsrc ! video/x-raw-rgb !
glupload ! gleffects effect=heat ! glimagesink" which uses 2 samplers
pointing at GL_TEXTURE1 and GL_TEXTURE2, and piglit

In short what the code did before:
__DRIscreen *psp = NULL;
if (pcp)
psp = pcp->psb;
assert(psp);
if (psp->stuff)
other_stuff();
return psb->even_more(pcp);
Remove all that stupid checking which still segfaults/asserts later on and
just do what we do in driUnbindContext. Also limited testing show libGL never
call driUnbindContext or driBindContext with cPriv == NULL.

doc additions: shader export ARRAY_BASE for EXPORT_POS: 60 is position,
61 is misc vec(VS_OUT_MISC_VEC - used here),
62, 63 are clip distance vectors(VS_OUT_CCDIST#)
sorry for formating - there seem to be so many different styles in r600

there's no more vp results for point coords so we cannot iterate
over vp outputs. Use only Point.CoordReplace[i]

bo_legacy->tobj cannot be NULL before the call to driUpdateTextureLRU.
There is a NULL check earlier in the routine, and if bo_legacy->tobj is
NULL, memory is allocated.

If there is no depth buffer bound to current context don't
enable depth test. GL states that if depth test is enabled
without depth buffer it's as if depth buffer always pass.
