2009-12-08gallium: use boolean instead of bool in p_refcnt.hRoland Scheidegger
all code in gallium should use boolean not bool

2009-12-04gallium: Disable force_align_arg_pointer attribute on x86_64.José Fonseca
Apparently not only unnecessary but also causes gcc to complain.

2009-12-03gallium: fix reference counting functions to be strict-aliasing compliantRoland Scheidegger
Historically, parts of mesa code are not strict-aliasing safe, hence -fno-strict-aliasing is needed to compile (this got forgotten for scons builds for gallium, which indeed not only caused compiler warnings but also unexplicable crashes in non-debug builds). However, we should try to eliminate code not complying with strict-aliasing code at least for gallium. Hence change pipe_reference functions to make them strict-aliasing compliant. This adds a bit more complexity (especially for derived classes) but is the right thing to do, and it does in fact fix a segfault.

2009-12-01gallium: Introduce separate vertex texture/sampler state.Michal Krol
Previously, gallium shared sampler and texture state between vertex and fragment shader stages. This change generalises this concept by providing separate entrypoints for vertex and fragment sampler state setting. A new capability bit is added to query the driver for the number of samplers that can be utilised by a vertex and fragment shader at the same time.
2009-11-30gallium: interface cleanups, remove nblocksx/y from pipe_texture and moreRoland Scheidegger
This patch removes nblocksx, nblocksy arrays from pipe_texture (can be recalculated if needed). Furthermore, pipe_format_block struct is gone completely (again, contains just derived state). nblocksx, nblocksy, block are also removed from pipe_transfer, together with the format enum (can be obtained from the texture associated with the transfer).

2009-11-27gallium: Remove tgsi_version token.Michal Krol
Not really needed, never served its purpose.
2009-11-24tgsi: reduce repetition of structure name in its membersKeith Whitwell
Rename Semantic.SemanticName to Semantic.Name. Similar for SemanticIndex, and the members of the tgsi_version struct.
2009-11-24gallium: simplify tgsi tokens furtherKeith Whitwell
Drop anonymous 'Extended' fields, have every optional token named explicitly in its parent. Eg. there is now an Instruction.Label flag, etc. Drop destination modifiers and other functionality which cannot be generated by tgsi_ureg.c, which is now the primary way of creating shaders. Pull source modifiers into the source register token, drop the second negate flag. The source register token is now full - if we need to expand it, probably best to move all of the modifiers to a new token and have a single flag for it.
2009-11-24gallium: Refactor the instruction predicate TGSI token.Michal Krol
Rename it to tgsi_instruction_predicate -- it's no longer an extended token. Its presence is indicated by a new flag in tgsi_instruction that indicates whether an instruction is predicated. Also, change predicate index representation to match the other tokens that specify register indices.
2009-11-19gallium: don't use arrays for texture width,height,depthKeith Whitwell
2009-11-06gallium: Add UNSYNCHRONIZED cpu access flag. Document others.José Fonseca
2009-11-02gallium: Cleanup predicate and condition code TGSI tokens.Michal Krol
There is little point in having a special TGSI token just to handle predicate register updates. Remove tgsi_dst_register_ext_predicate token and instead use a new PREDICATE register file to update predicates. Actually, the contents of the obsolete token are being moved to tgsi_instruction_ext_predicate, where they should be from the very beginning. Remove the NVIDIA-specific condition code tokens -- nobody uses them and they can be emulated with predicates if needed. Introduce PIPE_CAP_SM3 that indicates whether a driver supports SM3-level instructions, and in particular predicates. Add PIPE_CAP_MAX_PREDICATE_REGISTERS that can be used to query the driver how many predicate registers it supports (currently it would be 1).
2009-10-25gallium: Move enum pipe_error into p_defines.h.José Fonseca
It's really just another define. No need for its own header.
2009-10-23gallium: remove extended negate also, and also the ExtSwz tokenKeith Whitwell
Likewise, the extended negate functionality hasn't been used since mesa switched to using tgsi_ureg to build programs, and has been translating the SWZ opcode internally to a single MAD.
2009-10-23gallium: remove the swizzling parts of ExtSwizzleKeith Whitwell
These haven't been used by the mesa state tracker since the conversion to tgsi_ureg, and it seems that none of the other state trackers are using it either. This helps simplify one of the biggest suprises when starting off with TGSI shaders.
2009-10-23gallium: remove noise opcodesKeith Whitwell
Provide a dummy implementation in the GL state tracker (move 0.5 to the destination regs). At some point, a motivated person could add a better implementation of noise. Currently not even the nvidia binary drivers do anything more than this. In any case, the place to do this is in the GL state tracker, not the poor driver.
2009-10-17gallium: Permit surface_copy and surface_fill to be NULL.Corbin Simpson
Uf. Lots of files touched. Would people with working vega, xorg, dri1, etc. please make sure you are not broken, and fix yourself up if you are. There were only two or three places where the code did not have painful fallbacks, so I would advise st maintainers to find less painful workarounds, or consider overhauling util_surface_copy and util_surface_fill. Per ymanton, darktama, and Dr_Jakob's suggestions, clear has been left as-is. I will not add PIPE_CAP_BLITTER unless it is deemed necessary.
2009-10-14gallium: New ALIGN_STACK macro to tell gcc to align stack pointer.José Fonseca
2009-10-02gallium: Add PIPE_TRANSFER_MAP_DIRECTLY usage flag.Michel Dänzer
Asks the driver to map the texture storage directly or return NULL if that's not possible.
2009-10-02gallium: Preparations for adding more PIPE_TRANSFER_* usage flags.Michel Dänzer
Always test for PIPE_TRANSFER_READ/WRITE using the bit-wise and operator, and add a pipe_transfer_buffer_flags() helper for getting the buffer usage flags corresponding to them.
2009-10-01g3dvl: Copyright blocks.Younes Manton
2009-10-01g3dvl: Color space conv interface & vl impl.Younes Manton
Interface is pipe_video_context::set_csc_matrix(). vl_csc.h defines some helpers to generate CSC matrices based on one of the color standard and a user defined ProcAmp (brightness, contrast, saturation, hue).
2009-10-01util: define PIPE_OS_FREEBSD to correct u_cpu_detect on FreeBSD.Robert Noland
Since the various BSDs use some different features here, define PIPE_OS_OPENBSD and PIPE_OS_NETBSD as well Signed-off-by: Robert Noland <rnoland@2hip.net>
2009-10-01gallium: remove depth.occlusion_count flagKeith Whitwell
This was redundant as drivers can just keep track of whether they are inside a begin/end query pair. We want to add more query types later and also support nested queries, none of which map well onto a flag like this. No driver appeared to be using the flag.
2009-09-29gallium: New PIPE_OS_UNIX to simplify code that is portable to all unices.José Fonseca

2009-08-28drm_api: Operate on textures instead of buffersJakob Bornecrantz
Most use cases just got the buffer from the texture and then called into one of the get_handle functions. Also with this patch it would be easier to move to a generic function for getting handles from textures and textures from handles, that is exposed via the screen.

2009-08-17gallium: Make PIPE_TRANSFER_{READ,WRITE,READ_WRITE} bitmask friendly.Maarten Maathuis
2009-08-14gallium: Always map for READ flag when DISCARD is not set.José Fonseca
This prevents the driver from discarding a buffer when the whole buffer is mapped for writing, but only a portion is effectively written. This is a temporary fix, because WRITE shouldn't imply DISCARD. The full fix implies using PIPE_BUFFER_USAGE_DISCARD, throughout the code, and will go only into master.
2009-08-11gallium: Add texture usage information to surface_buffer_createJakob Bornecrantz
We need aditional meta data about the usage of the surface in softpipe because we need to be able tell the diffrence between PRIMARY and DISPLAY_TARGET surfaces.
