This is recommended by the B-Spec. I wasn't able to measure any
difference in ETQW.
|
|
This was obvious when looking at the compiled output of ETQW's
shaders.
|
|
Saves an instruction over doing conditional moves.

Allows compiz to work in depth 16.
The DRI2 getBuffersWithFormat hook is only required for 16/32 bit depth
buffers, for colour buffers the only requirement is that the format matches
the drawable depth, which we can't check here.

Lazily create a sampler view when the texture is being bound
for the first time.

The mapping for vertex_array_bgra:
(gl -> st -> translate)
GL_RGBA -> PIPE_FORMAT_R8G8B8A8 (RGBA) -> no swizzle (XYZW)
GL_BGRA -> PIPE_FORMAT_A8R8G8B8 (ARGB) -> ZYXW (BGRA again??)
Iẗ́'s pretty clear that PIPE_FORMAT_A8R8G8B8 here is wrong. This commit
fixes the pipe format and removes obvious workarounds in util/translate.
Tested with: softpipe, llvmpipe, r300g.

These should always be sanitized before heading towards the pipe driver,
and if the calling function explicitly marked them as invalid, we need
to regenerate them.
Allows r300g to properly pass a bit more of Wine's d3d9 testing without
dropping stuff on the floor.
|
|
Still commented out, of course.
|
|
Make the kernel even less likely to barf on us.

The format might have depth bits, stencil bits, or both. Add the
renderbuffers as needed.
|
|
Return a better format instead of an exact format in
choose_depth_stencil_format. Also, prefer formats with stencil bits.
|
|
It was a stupid typo by me when I refactored the code.

Switch from st_public.h to st_api.h. The latter has intrinsic multiple
APIs support and allows various EGLImage extensions to be supported.
|
|
This is done by defining one of st_module_OpenGL_ES1,
st_module_OpenGL_ES2, and st_module_OpenGL.
|
|
There is currently no user of this new interface. As the inteface can
coexist with st_public.h, everthing should work as before.
ST_TEXTURE_2D is both defined by st_public.h and st_api.h. Reorder the
headers in st/dri to avoid conflicts.

There is currently no user of this new interface. As the inteface can
coexist with st_public.h, everthing should work as before.
|
|
This is a new interface to be implemented by st/mesa, st/vesa, and the
window system APIs such as EGL or GLX.

The code can fairly easily be translated to llvm...

The stride depends on the mipmap level. Rename to row_stride to
distinguish from img_stride for 3D textures.
Fixes incorrect texel addressing in small mipmap levels.

|
Set the _NEW_BUFFERS flag and remove the code which updated the
parent framebuffer size. Normal Mesa state validation will do that.
Fixes issues with Warsow on r300g and possibly other bugs.
|
|
Make sure we always test for XEXT version.
Make sure that the user has a recent version of libkms and libdrm installed.
Note that the st/xorg code requires so new versions to work but these are
needed to make a proper vmwgfx_drv.so driver which is the only real user.
