* gallium: add PIPE_TEXTURE_RECT targetLuca Barbieri2010-08-201-1/+3
| | | | | | This allows to properly support OpenGL rectangle textures in a well defined way, especially on drivers that don't expose PIPE_CAP_NPOT_TEXTURES.
* gallium: add ALWAYS_INLINELuca Barbieri2010-08-111-0/+10
| | | | | Used when we want to be sure the compiler inlines a large function into an inner loop.
* gallium: Keep only pipe_context::draw_vbo.Chia-I Wu2010-07-291-41/+0
| | | | | | | That is, remove pipe_context::draw_arrays, pipe_context::draw_elements, pipe_context::draw_arrays_instanced, pipe_context::draw_elements_instanced, pipe_context::draw_range_elements.
* gallium: Add pipe_context::draw_vbo and pipe_context::set_index_buffer.Chia-I Wu2010-07-292-0/+41
| | | | | | This commit adds a new unified draw_vbo method to pipe_context. Unlike other draw methods, draw_vbo treats the index buffer as a state which is set with set_index_buffer.
* gallium: add depth clamp to the interfaceMarek Olšák2010-07-212-1/+3

* gallium: remove pointless bitfield restrction in pipe_vertex_elementKeith Whitwell2010-07-211-1/+1
| | | | | This used to be a somewhat packed struct, but no longer. Remove the last remaining bitfield tag.
* gallium: Ensure prototypes are wrapped in extern "C".José Fonseca2010-07-141-0/+11
| | | | | Fixes MSVC build failure due to inconsistent _ReadWriteBarrier prototype.
* gallium: Add a macro for memory barriers.José Fonseca2010-07-141-0/+19

* st_api: Remove st_context::is_visual_supported.Chia-I Wu2010-06-291-6/+0
| | | | | | | | The callback is used by st/vega to check if a visual specifies the depth/stencil format. It forces st/vega to be loaded by st/egl to perform the check. As noted in EGL spec, the depth/stencil format of a visual should not affect OpenVG. It should be better to ignore the field and always allocate the depth/stencil texture.
* mesa: initial support for ARB_geometry_shader4Zack Rusin2010-06-281-1/+3
| | | | | | laying down the foundation for everything and implementing most of the stuff. linking, gl_VerticesIn and multidimensional inputs are left.

| * gallium: Add drm driver interfaceJakob Bornecrantz2010-06-061-0/+71
| | | | | | | | | | | | | | This interfacre replaces the drm_api api it works very much the same way as drm_api but with the exception that its meant for the target to implement it. And it does not export a get function and neither a destroy function.
* | pipe: Add PIPE_OS_HURDnobled2010-06-241-0/+5
| | | | | | | | | | | | | | One tiny step toward porting Gallium to the GNU/Hurd kernel (and fixing Debian bug #585618). Signed-off-by: Corbin Simpson <[email protected]>
* | gallium: add a timestamp disjoint queryZack Rusin2010-06-221-1/+7
| | | | | | | | | | | | allows application to not only request the frequency of the TIME_ELAPSED clock but also to detect if that frequency was consistent throughout the entire bracketed range of graphics commands.
* | gallium: add a new queryZack Rusin2010-06-221-1/+2
| | | | | | | | to figure out if gpu is finished with all of the previously issues commands
* | gallium: add a temporary array register fileZack Rusin2010-06-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | like normal temporaries, but allows to define a number of distinct arrays, all of which make it explicit that they contain /indexable/ registers. as a side-effect we're adding support for multi-dimensional destination registers. The whole thing looks like this: DCL TEMPX[0][0..128] # 0 array with 128 registers ADD TEMPX[0][0], IN[0], IMM[0] ADD TEMPX[0][1], IN[0], IMM[0] ABS OUT[0], TEMPX[0][TEMP[0]]
* | gallium: add a new register file - immediate arrayZack Rusin2010-06-181-12/+13
| | | | | | | | | | | | allows one to specify a safe (bound checked) array filled with immediates. it works just like a const array and declares much like our current immediates.

| | | | | | | | | | | | | | interface wise we have everything needed by d3d10 and gl transform feedback. the draw module misses implementation of some corner cases (e.g. when stream output wants different number of components per output than normal rendering paths)

* mesa/st: add support for EXT_texture_swizzle.Dave Airlie2010-06-051-0/+1
| | | | | | | | | | | This passes on r300g, the only bit I'm not really sure about is the handling of the sampler_view in st_atom_texture.c, I unreference it there if the swizzle value changes and I also have to create a new set of functions to create a new one since the u_sampler.c ones don't handle swizzle so much. adds r300g + softpipe enables, I think other drivers could pass easily enough.

| * gallium: clear interface changesRoland Scheidegger2010-05-282-15/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm_api: Remove type argument from create screen callbackJakob Bornecrantz2010-05-251-18/+1
| | | | | With the removal of DRI1 support there where no use of this argument, some drivers didn't even properly check it.
* gallium: Remove dri1_api.h and winsys support for DRI1Jakob Bornecrantz2010-05-251-81/+0

| * gallium: clean up resource_copy_region functionRoland Scheidegger2010-05-171-2/+0
| | | | | | | | | | | | | | | | | | | | 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 Scheidegger2010-05-171-10/+2
| | | | | | | | | | | | | | | | | | | | 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.

| * | | | gallium: convert rasterizer state to use gl-style front/back conceptsKeith Whitwell2010-05-142-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use front/back instead of cw/ccw throughout. Also, use offset_point/line/fill instead of offset_cw/ccw. Brings gallium representation of this state into line with its main user, and also what turns out to be the most common hardware representation. This fixes a long-standing bias in the interface towards the architecture of the software rasterizer.
