2010-10-13gallium/format: add support for X24S8 and S8X24 formats.Dave Airlie
these formats are needed for hw that can sample and write stencil values. Signed-off-by: Dave Airlie <airlied@redhat.com>

this adds the capability + a stencil semantic id, + tgsi scan support. Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-09-17gallium/docs: added new pipeline.txt diagramBrian Paul
This diagram shows the rendering pipeline with an emphasis on the inputs/outputs for each stage. Some stages emit new vertex attributes and others consume some attributes.

2010-08-20gallium/docs: improve documentation for resourcesLuca Barbieri
2010-08-20gallium: add PIPE_TEXTURE_RECT targetLuca Barbieri
This allows to properly support OpenGL rectangle textures in a well defined way, especially on drivers that don't expose PIPE_CAP_NPOT_TEXTURES.

Per Jakob's request. Not super-pretty, but it's a good point for modding later.

2010-06-24gallium/docs: Vertex data formats.Corbin Simpson
I'm not sure if I really got it right. This seems like one of those "Duh, of course it works that way" things, but I'd like the documentation to be readable by people not acquainted with OGL/D3D.

2010-06-03gallium: rename clearRT / clearDS to clear_render_target / clear_depth_stencilRoland Scheidegger
more consistent with rest of gallium naming conventions. Also rename driver-internal names for these the same.
2010-06-01gallium/docs: Update FRAC -> FRC.José Fonseca
2010-05-28gallium: clear interface changesRoland Scheidegger
clears were a bit limited in gallium: - no scissoring (OGL only) nor explicit rectangle list (d3d9) - no color/stencil masks (OGL only) - no separate depth/stencil clears (d3d9/d3d10/OGL) - cannot really clear single color buffer (only with resource_fill_region) Additionally, d3d can clear surfaces not currently bound to the framebuffer. It is, however, not easy to find some common ground what a clear should be able to do, due to both API requirements and also hw differences (a case which might be able to use a special clear path on one hw might need a "normal" quad render on another). Hence several clear methods are provided, and a driver should implement all of them. - clear: slightly modified to also be able to clear only depth or stencil in a combined depth/stencil surface. This is however optional based on driver capability though ideally it wouldn't be optional. AFAIK this is in fact something used by applications quite a bit. Otherwise, for now still doesn't allow clearing with scissors/mask (or single color buffers) - clearRT: clears a single (potentially unbound) color surface. This was formerly roughly known as resource_fill_region. mesa st will not currently use this, though potentially would be useful for GL ClearBuffer. - clearDS: similar to above except for depth stencil surfaces. Note that clearDS/clearRT currently handle can handle partial clear. This might change however.

2010-05-17gallium: clean up resource_copy_region functionRoland Scheidegger
Previously, surface_copy was said to allow overlapping blits, and it was "optional". However, some state trackers actually assumed it is always present, and quite some code (like in u_blit) assumed overlapping isn't allowed. Hence, resource_copy_region (and in the same spirit, resource_fill_region) is now mandatory, but overlapping blits are no longer allowed. A driver can plug in the cpu fallback util_resource_copy_region if it does not want to provide its own implementation, though this is not optimal.
2010-05-17gallium: another interface change for multisamplingRoland Scheidegger
due to popular request, use nr_samples parameter in is_format_supported() instead of new is_msaa_supported() query. This makes it easily possible to query if a format with a given sample count is also supported not only as render target, but for sampler views (note that texture sampling from multisampled resources isn't supported yet). It is not quite how dx10 format msaa queries work, but we might need to revisit format queries completely in the future anyway.
2010-05-12gallium: Add new fine grained PIPE_CAP_xx for shader limits.José Fonseca
PIPE_CAP_GLSL and PIPE_CAP_SM3 not removed yet, as opcode support is not yet covered.
