Previously we created the pipe_surface during framebuffer validation.
But if we did a glCopyTex[Sub]Image() before anything else we wouldn't yet
have the surface. This fixes that.
|
|
We need to make sure the framebuffer state is up to date to make sure we
read pixels from the right buffer when doing a texture image copy.

Fixes a use-after-free reported in
http://bugs.freedesktop.org/show_bug.cgi?id=20539, so this possibly fixes that
bug. It has been confirmed to fix
http://bugs.freedesktop.org/show_bug.cgi?id=17895 .

Previously the pkg-config output files would contain e.g. `-lGL'
and `-lGLU', even if the user modified their configuration to
build libraries with different names. This modifies the
pkg-config inputs, and corresponding makery, so that modifying the
output library name will cause the appropriate updated name to
appear in the pkg-config `-l' option.

This function will check an instruction to see if there's data dependencies
between the dst and src registers if executed in an SOA manner.

It seems quake4 can hit these attributes sometimes.
|

Proper fix for this hasn't been identified, but avoid crashing.

RV410 SE chips only have 1 quadpipe.
Also, handle other R300 chip with quadpipe override

If a shader reaches an out-of-memory condition while adding
a new function (reallocating the function list), a segfault
will occur during cleanup (because the num_functions field
is non-zero, but the functions pointer is NULL).
This fixes that segfault by zeroing out the num_functions
field if reallocation fails.

Make the use_const_buffer field per-program and only call the code which
updates the constant buffer's data if the flag is set.
This should undo the perf regression from 20f3497e4b6756e330f7b3f54e8acaa1d6c92052

We were incorrectly applying the destination texture face and level
when requesting a transfer to the temporary texture, which has only
one face and level. This would obviously cause problems uploading to
compressed cube and mipmap textures.

This interface gives the driver two important features. First, it can
allocate the (fake) front-buffer only when needed. Second, it can
tell the buffer allocator the format of buffers being allocated. This
enables support for back-buffer and depth-buffer with different bits
per pixel.

As of commit 23ad86cfb91c294ce85a3116d4b825aaa3988a6e all messages go
through output_if_debug().
Add new parameter to output_if_debug() to indicate whether to emit a newline.
_mesa_warning() and _mesa_error() calls should not end their strings with \n.
_mesa_debug() calls should end their text with \n.

dri_bo_subdata()
This wraps up the unfinished business from commit a9a363f8298e9d534e60e3d2869f8677138a1e7e

need to clamp point size to user set min/max values, even for constant
point size. Fixes glean pointAtten test.
|
|
|
|
The drm_intel_gem_bo_map_gtt() call that replaced dri_bo_map() is
producing errors like:
intel_bufmgr_gem.c:689: Error preparing buffer map 39 (vp_const_buffer): Invalid argument .
and returning NULL, causing a segfault in the memcpy().
Just reverting until we can get to the root issue...
|
|
forgot to commit the changes to actually support 4x aniso filtering...
|
|
Also fixes drawing to 3D texture depth levels.
|
|
This is a CPU win in general, but in particular reduces the pain of
Mesa's calculation of min/max indices in DrawElements (wtf?).
|
|
Call FLUSH_VERTICES() in _mesa_Histogram().
No need to signal _NEW_PIXEL in ResetHistogram(), ResetMinmax().

|

Calling _mesa_dump_textures() deleted the textures... oops!!!

i915 actually supports up to 4 (according to header file - not tested),
i965 up to 16 (code already handled this but slightly broken), so don't use 2
for all chips, even though angular dependency is very high.

This is a follow-on to commit c1a3b852807fb160f0cd246c1364b7336b4b947e.
Note that (at this time) wherever _NEW_PROGRAM_CONSTANTS is set we're still
setting _NEW_PROGRAM so this won't really make any difference (for now).

Need to do this to ensure vbo code unmaps its buffers before calling
the driver, which may be sitting on top of a memory manager which
objects to firing commands from a mapped buffer.
|
|
When a new program is bound but no constants are updated we still need
to update the Gallium const buffer.
|
|
|
|
We can simplify this now that we no longer have any dynamic atoms.
|
|
Just use the new _NEW_PROGRAM_CONSTANTS flag instead.
|
|
This state flag will be used to indicate that vertex/fragment program
constants have changed. _NEW_PROGRAM will be used to indicate changes
to the vertex/fragment shader itself, or misc related state.
_NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's
tracking GL state has changed. For example, if the projection matrix is
in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS
to be set. This will let to remove the need for dynamic state atoms in
some drivers.
For now, we still set _NEW_PROGRAM in all the places we used to. We'll no
longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.
