We need to always at least export one component (wether it's depth
or color. Add valid r7xx shader program for depth decompression.

util_fill_rect could not handle formats with more than 32 bits,
since the fill color was a uint32_t value. Fix this by using
a util_color union instead, and also expand the union so it
works with formats which have up to 256 bits (the max of any
format currently defined).

Should improve performance, possibly significantly.

Gallium always puts gl_PointCoord in GENERIC[0] if
point_quad_rasterization is enabled.
This is silly, but for now it makes mesa-demos/glsl/pointcoord work.

Before, we were discarding the compiled vertex program on each
vertex program change.
Now we compile the program as if there were 6 clip planes and
dynamically patch in an "end program" bit at the right place.
Also, nv30 should now work.

the current code reuses the same vbo over and over, however after a flush
we'd stall and wait for mapping on the vbo when we should just fire and forget.
On a gears test this brings me from ~620 to ~750 on my rv530 in swtcl mode.

Now we lie less when claiming OpenGL 2 support.
Also, first piglit result group is now all green, except for
fdo25614-genmipmap, which seems mesa/st's fault.

Include draw_context.h for draw_*_vertex_shader symbols.
Fixes the following GCC warning.
nvfx_vertprog.c: In function 'nvfx_vp_state_create':
nvfx_vertprog.c:1276: warning: implicit declaration of function 'draw_create_vertex_shader'
nvfx_vertprog.c:1276: warning: assignment makes pointer from integer without a cast
nvfx_vertprog.c: In function 'nvfx_vp_state_delete':
nvfx_vertprog.c:1298: warning: implicit declaration of function 'draw_delete_vertex_shader'

Changed by me to use movd instead of movss to avoid penalties.

Before using depth buffer as texture, it needs to be decompressed
(tile pattern of db are different from one used for colorbuffer
like texture)

Introduce a new configuration option XMESA_STRICT_INVALIDATE to switch
between swapbuffers-based and glViewport-based buffer invalidation.
Default strict invalidate to false, ie glViewport-based invalidation,
aka ST_MANAGER_BROKEN_INVALIDATE.
This means we will not call XGetGeometry after every swapbuffers,
which allows swapbuffers to remain asynchronous. For apps running at
100fps with synchronous swapping, a 10% boost is typical. For gears,
I see closer to 20% speedup.
Note that the work of copying data on swapbuffers doesn't disappear -
this change just allows the X server to execute the PutImage
asynchronously without us effectively blocked until its completion.
This applies even to llvmpipe's threaded rasterization as the
swapbuffers operation was a large part of the serial component of an
llvmpipe frame.
The downside of this is correctness - applications which don't call
glViewport on window resizes will get incorrect rendering, unless
XMESA_STRICT_INVALIDATE is set.
The ultimate solution would be to have per-frame but asynchronous
invalidation. Xcb almost looks as if it could provide this, but the
API doesn't seem to quite be there.

Don't spend as much time comparing them.

If bins outside the current scene bounds are being corrupted, we'll
need to fix that separately. Currently seems ok though.
|
|
|
|
With this change, xmesa_get_window_size still does one round trip, but
that's better than doing two.
|
|
Try to eliminate some unnecessary X server round trips.
|
|
This version should hopefully be much clearer and thus less likely
to be subtly broken.
Also fixes point sprites on nv40 and possibly some other bugs too.

There may actually be something mapped in that range, especially for large
buffers like e.g. the GL Drawable.

How to cope with NULL surface relocations should be entirely at winsys'
discretion.

Partialy fix texturing from depth buffer, depth buffer is tiled
following different tile organisation that color buffer. This
properly set the tile type & array mode field of texture sampler
when sampling from db resource.
Add initial support to untiling buffer when transfering them,
it's kind of broken by corruption the vertex buffer of previous
draw.

This is valid input, and asserting here does causes the test suites that
verify this to crash.
Also, the assert was wrongly accepting the case
max_index == vert_info->count
which, IIUC, is the first vertex outside the buffer. Assuming the
vert_info->count is precise (which often is not the case).
