1. add PROGRAM_CONSTANT to switch() in src_vector().
2. use _mesa_append_fog_code() to handle fog options in i915ProgramStringNotify().
3. Re-enable some vertex attribute emit code that was previously disabled in i915ValidateFragmentProgram().

This way we no longuer have the fixed RADEON_BUFFER_SIZE.
Anyway function calling AllocDmaRegion should check if this
succeed and fail gracefuly if not (see bug 8348).

CMPH a0, a1, a2 -> if a2 > 0.5 return a1 else return a0
Guessed by examinating LIT instruction handling of FGLRX.

Properly resize bith the drawable and the readable in mgaUpdateRects.
Eliminate the use of the deprecated GetBufferSize interface. Bump
driver date.

Combine mgaXMesaSetFrontClipRects and mgaXMesaSetBackClipRects into a
single new function called mga_set_cliprects. This enables a small
refactor in mgaDDDrawBuffer.

In the software rasterization fallbacks, get the __DRIdrawablePrivate
pointer from the driRenderbuffer that is passed in. This eliminates
the need for the mesa_drawable pointer in MGA context structure.
This partially fixes bug #8799. wincopy no longer produces a black
window for the destination window, but it does produce incorrect
results if the destination window is resized.

and instead use _mesa_insert_mvp_code().

computation into the vertex program (not yet fixed for swtnl). Simplify (and correct) the VTX_TCL_OUTPUT_VTXFMT handling when using vertex programs, turns out it's solely driven by the needs of the past-vertex stage of the pipeline, this should fix lockups with ill-specified applications using vertex programs (for instance applications enabling fog but not writing to fog coord output will now get (conformant) undefined results instead of lockups).
|
|
passing them to the kernel. This works because all drawing commands
in the 965 driver are emitted with the lock held and the batchbuffer
is always flushed prior to releasing the lock. This allows multiple
cliprects to be dealt with, without replaying entire batchbuffers and
redundantly re-emitting state.

Added code to track the drawable bound to the context for reading. In
addition, when a drawable is initially bound (for reading or drawing)
or when the size of the drawable changes, update the size of the
framebuffer object that back the drawable (for software fallbacks).
Deprecate the old GetBufferSize interface.
Bump the driver date.
These changes were tested with wincopy on both direct rendering and
accelerated indirect rendering (AIGLX).

The coordinates need to be computed after we've got the hw lock.
Code updated to:
1. Ignore all/x/y/width/height/ params passed to Clear func.
2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.

Always check window size in XMesaMakeCurrent() in case glViewport is not
called.

may be temporary

Only need to call _mesa_resize_framebuffer() when we've detected a window
size change.
Set the drawFb->Initalized flag to GL_TRUE to avoid obsolete
Driver.GetBufferSize/ResizeBuffer calls in the Mesa code.

four rgba values set for radeon and r200 (discovered with a modified glean pixelFormats test, noone ever noticed in over 2 years). For radeon, use hw format I8 as previously, and change tex env to make the correct default values appear for both GL_ALPHA and GL_LUMINANCE textures. For r200, which supports GL_LUMINANCE just fine, use the AL88 hw format for GL_ALPHA textures, since it seems like it's probably not worth the effort to fix up the texture environment (certainly complicated in case of ATI_fragment_shader programs).
