* draw: simplify index buffer specificationBrian Paul2012-05-315-43/+24
| | | | | Replace draw_set_index_buffer() and draw_set_mapped_index_buffer() with draw_set_indexes() which simply takes a pointer and an index size.
* draw: fix primitive restart bug by using the index buffer offsetBrian Paul2012-05-251-3/+6
| | | | | | | | | | | The code which scans the index buffer for restart indexes wasn't adding the index buffer offset so we were always starting at offset=0. The offset is usually zero so it wasn't noticed before. Fixes a failure in the piglit primitive-restart test when testing vertex data + index data in a single VBO. NOTE: This is a candidate for the 8.0 branch.

* draw,llvmpipe: Avoid named struct types on LLVM 3.0 and later.José Fonseca2012-05-161-20/+4
| | | | | | | | | | | | Starting with LLVM 3.0, named structures are meant not for debugging, but for recursive data types, previously also known as opaque types. The recursive nature of these types leads to several memory management difficulties. Given that we don't actually need recursive types, avoid them altogether. This is an attempt to address fdo bugs 41791 and 44466. The issue is somewhat random so there's no easy way to check how effective this is.

* | gallium: Add pipe loader for device enumeration and driver multiplexing.Francisco Jerez2012-05-118-0/+666
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal is to have a uniform interface to create winsys and pipe_screen instances for any driver, exposing the device enumeration capabilities that might be supported by the operating system (for now there's a "drm" back-end using udev and a "sw" back-end that always returns the same built-in devices). The typical use case of this library will be: > > struct pipe_loader_device devs[n]; > struct pipe_screen *screen; > > pipe_loader_probe(&devs, n); >[pick some device from the array...] > > screen = pipe_loader_create_screen(dev, library_search_path); >[do something with screen...] > > screen->destroy(screen); > pipe_loader_release(&devs, N); > A part of the code was taken from targets/gbm/pipe_loader.c, which will be removed and replaced with calls into this library by a future commit.

* | gallium/tgsi: Introduce the "LOCAL" register declaration modifier.Francisco Jerez2012-05-113-26/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change will be useful to implement function parameter passing on top of TGSI. As we don't have a proper stack, a register-based calling convention will be used instead, which isn't necessarily a bad thing given that GPUs often have plenty of registers to spare. Using the same register space for local temporaries and inter-procedural communication caused some inefficiencies, because in some cases the register allocator would lose the freedom to merge temporary values together into the same physical register, leading to suboptimal register (and sometimes, as a side effect, instruction) usage. The LOCAL declaration modifier specifies that the value isn't intended for parameter passing and as a result the compiler doesn't have to give any guarantees of it being preserved across function boundaries. Ignoring the LOCAL flag doesn't change the semantics of a valid program in any way, because local variables are just supposed to get a more relaxed treatment. IOW, this should be a backwards-compatible change.

* | gallium/tgsi: Add support for raw resources.Francisco Jerez2012-05-113-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normal resource access (e.g. the LOAD TGSI opcode) is supposed to perform a series of conversions to turn the texture data as it's found in memory into the target data type. In compute programs it's often the case that we only want to access the raw bits as they're stored in some buffer object, and any kind of channel conversion and scaling is harmful or inefficient, especially in implementations that lack proper hardware support to take care of it -- in those cases the conversion has to be implemented in software and it's likely to result in a performance hit even if the pipe_buffer and declaration data types are set up in a way that would just pass the data through. Add a declaration flag that marks a resource as typeless. No channel conversion will be performed in that case, and the X coordinate of the address vector will be interpreted in byte units instead of elements for obvious reasons. This is similar to D3D11's ByteAddressBuffer, and will be used to implement OpenCL's constant arguments. The remaining four compute memory spaces can also be understood as raw resources.
* | gallium/tgsi: Define the TGSI_BUFFER texture target.Francisco Jerez2012-05-113-3/+3
| | | | | | | | | | | | This texture type was already referred to by the documentation but it was never defined. Define it as 0 to match the pipe_texture_target enumeration values.

| | | | | | | | | | | | Move Interpolate, Centroid and CylindricalWrap from tgsi_declaration to a separate token -- they only make sense for FS inputs and we need room for other flags in the top-level declaration token.
