* translate_sse: Use the correct buffer index in this fast path.Andreas Hartmetz2014-04-291-1/+3
| | | | | | | | | | | | It is possible that there are multiple input buffers but only one is relevant for translation. Then there will be only a single translation group, which might need to source data from a buffer index != 0. Fixes wrong vertex shader inputs as observed while debugging with an application and driver combination that requires translation of a vertex attribute in a non-trivial set of attributes and input buffers.

* translate: fix buffer overflowsZack Rusin2014-03-044-6/+18
| | | | | | | | | | | | | | Because in draw we always inject position at slot 0 whenever fragment shader would take the maximum number of inputs (32) it meant that we had PIPE_MAX_ATTRIBS + 1 slots to translate, which meant that we were crashing with fragment shaders that took the maximum number of attributes as inputs. The actual max number of attributes we need to translate thus is PIPE_MAX_ATTRIBS + 1.

* translate: deal with size overflows by casting to ptrdiff_tIlia Mirkin2014-01-272-3/+7
| | | | | | | | | | | This was discovered as a result of the draw-elements-base-vertex-neg piglit test, which passes very negative offsets in, followed up by large indices. The nouveau code correctly adjusts the pointer, but the translate code needs to do the proper inverse correction. Similarly fix up the SSE code to do a 64-bit multiply to compute the proper offset.

* translate_sse: Fix generated code argument handling for msabi on x86_64Jon TURNEY2013-10-181-3/+11
| | | | | | | | | | | | | | | | translate_sse.c contains code for msabi on x86_64, but it appears to be untested. Currently arguments 1 and 2 passed to the generated code are moved as 32-bit quantities into the registers used by sysvabi, irrespective of the architecture. Since these may be pointers, they must be moved as 64-bit quantities to avoid truncation. Commit f4dd0991719ef3e2606920c5100b372181c60899 disabled tranlate_sse.c on MinGW x86_64, I don't know if was due to this issue, or a different one...

* draw: cleanup and fix instance id computationZack Rusin2013-07-252-6/+1
| | | | | | | | | | | | | | The instance id system value always starts at 0, even if the specified start instance is larger than 0. Instead of implicitly setting instance id to instance id plus start instance and then having to subtract instance id when computing the buffer offsets lets just set instance id to the proper instance id. This fixes instance id computation and cleansup buffer offset computation.

* draw/translate: fix instancingZack Rusin2013-06-283-11/+42
| | | | | | | | | | | | | | | | | | We were incorrectly computing the buffer offset when using the instances. The buffer offset is always equal to: start_instance * stride + (instance_num / instance_divisor) * stride We were completely ignoring the start instance quite often producing instances that completely wrong, e.g. if start instance = 5, instance divisor = 2, then on the first iteration it should be: 5 * stride, not (5/2) * stride as we'd have currently, and if start instance = 1, instance divisor = 3, then on the first iteration it should be: 1 * stride, not 0 as we'd have. This fixes it and adjusts all the code to the changes. Signed-off-by: Zack Rusin <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NOTE: Win64 is untested, and is thus currently disabled. If you have such a system, please enable it and report whether it works. To enable it, change src/gallium/auxiliary/translate/translate.c Changes in v5: - On Win64, preserve %xmm6 and %xmm7 as required by the ABI - Use _WIN64 instead of WIN64 Changes in v4: - Use x86_target() and x86_target_caps() - Enable translate_sse in x86-64, but not in Win64 Changes in v3: - Win64 support (untested) - Use u_cpu_detect.h constants instead of #ifs Changes in v2: - Minimize #ifs - Give a name to magic number CHANNELS_0001 - Add support for CPUs without SSE (only memcpy and swizzles, like non SSE2) - Fixed comments translate_sse is currently very limited to the point of being useless in essentially all cases. In particular, it only support some float32 and unorm8 formats and doesn't work on x86-64. This commit rewrites it to support: 1. Dumb memory copy for any pair of identical formats 2. All formats that are swizzles of each other 3. Converting 32/64-bit floats and all 8/16/32-bit integers to 32-bit float 4. Converting unorm8/snorm8 to snorm16 and uscaled8/sscaled8 to sscaled16 5. Support for x86-64 (doesn't take advantage of it in any way though) This new translate can even be useful to translate index buffers for cards that lack 8-bit index support. It passes the testsuite I wrote, but note that this is a major change, and more testing would be great.
* translate: add support for 8/16-bit indicesLuca Barbieri2010-08-163-19/+92
| | | | | Currently, only 32-bit indices are supported, but some use cases translate needs support for all types.
* translate_sse: remove useless generated function wrappersLuca Barbieri2010-08-161-51/+4
| | | | | | | | | | Currently translate_sse puts two trivial wrappers in the translate vtable. These slow it down and enlarge the source code for no gain, except perhaps the ability to set a breakpoint there, so remove them. Breakpoints can be set on the caller of the translate functions, with no loss of functionality.
* translate_generic: factor out common code between linear and indexedLuca Barbieri2010-08-161-115/+62
| | | | This moves the common code into a separate ALWAYS_INLINE function.
* translate_generic: use memcpy if possible (v3)Luca Barbieri2010-08-161-33/+75
| | | | | | | | | | | | | | | | | | | | | | | | Changes in v3: - If we can do a copy, don't try to get an emit func, as that can assert(0) Changes in v2: - Add comment regarding copy_size When used in GPU drivers, translate can be used to simultaneously perform a gather operation, and convert away from unsupported formats. In this use case, input and output formats will often be identical: clearly it would make sense to use a memcpy in this case. Instead, translate will insist to convert to and from 32-bit floating point numbers. This is not only extremely expensive, but it also loses precision for 32/64-bit integers and 64-bit floating point numbers. This patch changes translate_generic to just use memcpy if the formats are identical, non-blocked, and with an integral number of bytes per pixel (note that all sensible vertex formats are like this).
* translate: allow clients to ask for supported output formatsLuca Barbieri2010-08-113-0/+88
| | | | | | | | | | | | | Currently translate asserts on unsupported output formats, making it impossible to use for some purposes, such as testing whether it actually works on all formats it supports. Removing the assert was met with opposition, so this change allows clients to ask whether an output format is supported, and they are thus able to avoid attempting to use it. Since this is just an addition to the API, no adverse effect is possible, and it makes the testsuite work again.
