* gallium: Add a cap for offset_units_unscaledAxel Davy2016-06-252-0/+8
| | | | | | | | | | | | | | D3D9 has a different behaviour for depth bias. For OGL/D3D1X, the depth bias unit is the minimal resolvable value for the depth buffer, which depends on the format (and has different behaviour for float depth buffers). For D3D9, the depth bias unit is 1.0f. Signed-off-by: Axel Davy <[email protected]> Reviewed-by: Marek Olšák <[email protected]>

* gallium: add API for setting window rectanglesIlia Mirkin2016-06-181-3/+14
| | | | | | | | | | | | | | | | | | Window rectangles apply to all framebuffer operations, either in inclusive or exclusive mode. They may also be specified as part of a blit operation. In exclusive mode, any fragment inside any of the specified rectangles will be discarded. In inclusive mode, any fragment outside every rectangle will be discarded. The no-op state is to have 0 rectangles in exclusive mode. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]>

* gallium: Add a pipe cap for whether primitive restart works for patches.Kenneth Graunke2016-05-231-0/+2
| | | | | | | | | | | | | | | Some hardware supports primitive restart on patch primitives, and other hardware does not. Modern GL and ES include a query for this feature; adding a capability bit will allow us to answer it. As far as I know, AMD hardware does not support this feature, while NVIDIA and Intel hardware does. However, most Gallium drivers do not appear to support tessellation shaders yet. So, I've enabled it for nvc0 and disabled it everywhere else.

* nouveau: codegen: LOAD: Take src swizzle into accountHans de Goede2016-04-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | The llvm TGSI backend uses pointers in registers and does things like: LOAD TEMP[0].y, MEMORY[0], TEMP[0] Expecting the data at address TEMP[0].x to get loaded to TEMP[0].y. But this will cause the data at TEMP[0].x + 4 to be loaded instead. This commit adds support for a swizzle suffix for the 1st source operand, which allows using: LOAD TEMP[0].y, MEMORY[0].xxxx, TEMP[0] And actually getting the desired behavior Signed-off-by: Hans de Goede <[email protected]> Reviewed-by: Samuel Pitoiset <[email protected]> Reviewed-by: Ilia Mirkin <[email protected]>

* gallium: Add PIPE_CAP_FRAMEBUFFER_NO_ATTACHMENTEdward O'Callaghan2016-04-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add PIPE_CAP to determine if the GL extension 'GL_ARB_framebuffer_no_attachments' shall be supported. The driver is required to support 'PIPE_FORMAT_NONE' via its 'is_format_supported()' callback in order to determine the MSAA modes the hardware supports so that values requested from the application using 'GL_ARB_framebuffer_no_attachments' may be quantized to what the hardware expects. V.2: Fix doc for a more detailed description of the PIPE_CAP and the corresponding GL constant. V.3: Renamed and repurposed once again. V.4: Remove CAP from cap_mapping array.

* gallium: distinguish between shader IR in get_compute_paramBas Nieuwenhuizen2016-04-021-9/+9
| | | | | | | | | | | | | For radeonsi, native and TGSI use different compilers and this results in different limits for different IR's. The set we strictly need for radeonsi is only the MAX_BLOCK_SIZE and MAX_THREADS_PER_BLOCK params, but I added a few others as shader related that seemed like they would also typically depend on the compiler.

* gallium: add TGSI property NEXT_SHADERMarek Olšák2016-03-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Radeonsi needs to know which shader stage will execute after a shader in order to make the best decision about which shader variant to compile first. This is only set for VS and TES, because we don't need it elsewhere. VS has 3 variants: - next shader is FS - next shader is GS - next shader is TCS TES has 2 variants: - next shader is FS - next shader is GS Currently, radeonsi always assumes the next shader is FS, which is suboptimal, since st/mesa always knows which shader is next if the GLSL program is not a "separate shader". By default, ureg always sets "next shader is FS". Reviewed-by: Nicolai Hähnle <[email protected]>
