| * gallium: clear interface changesRoland Scheidegger2010-05-282-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * gallium: clean up resource_copy_region functionRoland Scheidegger2010-05-171-4/+3
| | | | | | | | | | | | | | | | | | | | 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.
| * gallium: another interface change for multisamplingRoland Scheidegger2010-05-171-11/+3
| | | | | | | | | | | | | | | | | | | | 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.

Also make it possible to query for supported sample count with is_msaa_supported(). Use explicit resource_resolve() to resolve a resource. Note that it is illegal to bind a unresolved resource as a sampler view, must be resolved first (as per d3d10 and OGL APIs, binding unresolved resource would mean that special texture fetch functions need to be used which give explicit control over what samples to fetch, which isn't supported yet). Also change surface_fill() and surface_copy() to operate directly on resources. Blits should operate directly on resources, most often state trackers just used get_tex_surface() then did a blit. Note this also means the blit bind flags are gone, if a driver implements this functionality it is expected to handle it for all resources having depth_stencil/render_target/sampler_view bind flags (might even require it for all bind flags?). Might want to introduce quality levels for MSAA later. Might need to revisit this for hw which does instant resolve.
