* tgsi: add caps for fragment coord conventions (v3)Luca Barbieri2010-01-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes in v3: - Renumber caps to accomodate caps to add to master in the meantime - Document caps - Add unsupported caps to *_screen.c too Changes in v2: - Split for properties patch - Use positive caps instead of negative caps This adds 4 caps to indicate support of each of the fragment coord conventions. All drivers are also modifed to add the appropriate caps. Some drivers were incorrectly using non-Gallium-default conventions, and caps for them have them set so that they will behave correctly after the later state tracker patches. This drivers are softpipe/llvmpipe (uses integer rather than half integer) and pre-nv50 Nouveau (uses lower left rather than upper left). Other drivers might be broken. With this patchset, fixing them is only a matter of exposing the appropriate caps that match the behavior of the existing code. Drivers are encouraged to support all conventions themselves for better performance, and this feature is added to softpipe in a later patch.
* tgsi: add properties for fragment coord conventions (v3)Luca Barbieri2010-01-291-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Changes in v3: - Documented the new properties - Added comments for property values - Rebased to current master Changes in v2: - Caps are added in a separate, subsequent patch This adds two TGSI fragment program properties that indicate the fragment coord conventions. The properties behave as described in the extension spec for GL_ARB_fragment_coord_conventions, but the default origin in upper left instead of lower left as in OpenGL. The syntax is: PROPERTY FS_COORD_ORIGIN [UPPER_LEFT|LOWER_LEFT] PROPERTY FS_COORD_PIXEL_CENTER [HALF_INTEGER|INTEGER] The names have been chosen for consistency with the GS properties and the OpenGL extension spec. The defaults are of course the previously assumed conventions: UPPER_LEFT and HALF_INTEGER.

| * gallium: remove PIPE_CAP_S3TC, and add PIPE_CAP_DUAL_SOURCE_BLENDRoland Scheidegger2010-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | there's no point in keeping deprecated PIPE_CAPS around since there's no stable interface (yet). Reuse the enum for PIPE_CAP_DUAL_SOURCE_BLEND. Drivers advertizing this will accept the pipe blendfactors with SRC1 in them and be able to do dual source blending (src color from pixel shader output 0, and blendfactor with SRC1 will come from output 1, only one render target may be bound when using any of these blend factors).

| * gallium: prepare for per-rendertarget blend enables, writemasks, blend funcsRoland Scheidegger2010-01-201-3/+8
| | | | | | | | | | | | | | | | GL 3.0 (EXT_draw_buffers2) and other APIs allow independent blend enables and write masks per render target, ARB_draw_buffers_blend (and other APIs) also allow independent blend functions. Things like dithering, logic ops however are not extended to be per rendertarget, that might be conceptually possible however it doesn't look like any API wants to expose this.

* | | | gallium: Provide alternative stdint.h and stdbool.h C99 headers, instead of ↵José Fonseca2010-01-101-34/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ad-hoc definitions. Everybody is using the C99's integer types. Everybody except Microsoft, which in turns means everybody is including their own definitions of C99 integer types for MSVC, causing duplicate definitions when linking two projects. This is the case of building Gallium and LLVM with MSVC. Shipping alternative stdint.h and stdbool.h headers for MSVC allows us to share a single definition. It also removes clutter from the Gallium headers.
* | | | gallium: remove PIPE_TEX_FILTER_ANISOLuca Barbieri2010-01-061-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes PIPE_TEX_FILTER_ANISO. Anisotropic filtering is enabled if and only if max_anisotropy > 1.0. Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be considered equivalent, and meaning to turn off anisotropic filtering. This approach has the small drawback of eliminating the possibility of enabling anisotropic filter on either minification or magnification separately, which Radeon hardware seems to support, is currently support by Gallium but not exposed to OpenGL. If this is actually useful it could be handled by splitting max_anisotropy in two values and adding an appropriate OpenGL extension. NOTE: some fiddling & reformatting by keithw to get this patch to apply. Hopefully nothing broken in the process.

* | | | gallium: remove TGSI_SEMANTIC_VERTICESZack Rusin2009-12-251-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | it's a leftover from an early version of geometry shading support. geometry shaders now encode the primitive size in the PROPERTY token and don't need special input with their size.
* | | | gallium: geometry shader can be always enabled and we don't need a cap for thatZack Rusin2009-12-251-1/+0
| | | | | | | | | | | | | | | | | | | | using the draw module allows us to enable geometry shading even on hardware that doesn't support it.
