* util,gallivm: Explicitly enable/disable fma attribute.Jose Fonseca2016-06-101-0/+1
| | | | | | | | | | As suggested by Roland Scheidegger. Use the same logic as f16c, since fma requires VEX encoding. But disable FMA on LLVM 3.3 without MCJIT. Reviewed-by: Roland Scheidegger <[email protected]>

* gallium/util: make sure cache line size is not zeroLeonid Shatz2015-01-051-1/+5
| | | | | | | | | | The "normal" detection (querying clflush size) already made sure it is non-zero, however another method did not. This lead to crashes if this value happened to be zero (apparently can happen in virtualized environments at least). This fixes https://bugs.freedesktop.org/show_bug.cgi?id=87913 Cc: "10.4" <[email protected]>
* gallium/util: fix crash with daz detection on x86Roland Scheidegger2015-01-051-1/+1
| | | | | | | | | | The code used PIPE_ALIGN_VAR for the variable used by fxsave, however this does not work if the stack isn't aligned. Hence use PIPE_ALIGN_STACK function decoration to fix the segfault which can happen if stack alignment is only 4 bytes. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=87658.

* util: don't try to emit half-float intrinsics if avx isn't availableRoland Scheidegger2014-09-191-1/+1
| | | | | | | | | These instructions only have vex encodings, thus they can't be used without avx. (Technically, one can still use avx-128 if avx isn't available because the environment doesn't store the ymm registers, however I don't think llvm can.) Reviewed-by: Jose Fonseca <[email protected]>

* util: add avx2 and xop detection to cpu detection codeRoland Scheidegger2013-08-201-0/+48
| | | | | | | | | | Going to need this soon (not going to bother with avx2 intrinsics at this time but don't want to do workarounds for true vector shifts if llvm itself can use them just fine and won't need the gazillion instruction emulation). Not really tested other than my cpu returns 0 for these features... (I have no idea if llvm actually would emit avx2/xop instructions neither...) Reviewed-by: Jose Fonseca <[email protected]>
* util: (trivial) fix asm input/output list for fxsaveRoland Scheidegger2013-08-091-1/+1
| | | | | Otherwise gcc might do very unsafe optimizations, spotted by Uros Bizjak. Hopefully this time it's finally right?

* util: try much harder to set DAZ flagRoland Scheidegger2013-08-081-0/+29
| | | | | | | | | | | | | | | | | | While so far this only causes some harmless test failures, there's lots more cpus with DAZ. All 64bit capable ones can do it (particularly relevant for AMD cpus as they supported sse3 very very late) but if really necessary we can check support for that for real with some more magic. (In fact just about ANY cpu with sse2 can support DAZ, I believe the only exception are first gen P4 (Willamette) and from those only early steppings which can't do it it's almost like intel forgot to add it... - a real pity though docs say you can't just try to set it as they will throw a GPF.) While this was meant to address https://bugs.freedesktop.org/show_bug.cgi?id=67672 it does not fix it. Most likely the tests need fixing as I don't think there's any guarantee about denorm handling in the reference math library functions if the flags aren't set to standard values. Nevertheless enabling DAZ on all cpus which can do it should be the right thing to do. Reviewed-by: Jose Fonseca <[email protected]>
* gallium/util: Fix detection of AVX cpu capsAndre Heider2013-07-231-2/+25
| | | | | | | | | | | | | | | | | For AVX it's not sufficient to only rely on the cpuid flags. If the CPU supports these extensions, but the OS doesn't, issuing these insns will trigger an undefined opcode exception. In addition to the AVX cpuid bit we also need to: * test cpuid for OSXSAVE support * XGETBV to check if the OS saves/restores AVX regs on context switches See "Detecting Availability and Support" at http://software.intel.com/en-us/articles/introduction-to-intel-advanced-vector-extensions Signed-off-by: Andre Heider <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]> Reviewed-by: José Fonseca <[email protected]>
* util: (trivial) add has_popcnt fieldRoland Scheidegger2013-06-191-0/+1
| | | | | | Not used yet but there's a couple of places in llvmpipe which should use this (occlusion count is currently very inefficent if there's no cpu popcnt instruction).
* util: Use sizeof(void *) rather than 0 as the fallback cache line sizeRichard Sandiford2013-06-101-0/+5
| | | | | | | | Without this, llvmpipe ends up giving a zero size to all uncompressed textures on non-x86 systems, since align() cannot handle a 0 alignment. Reviewed-by: Adam Jackson <[email protected]> Signed-off-by: Richard Sandiford <[email protected]>

* util: Remove check_os_katmai_support.Vinson Lee2010-08-161-119/+1
| | | | | | | | | | | | | | | | | check_os_katmai_support checks that the operating system running on a SSE-capable processor supports SSE. This is necessary for unpatched 2.2.x and earlier kernels. 2.4.x and later kernels support SSE. check_os_katmai_support will disable SSE capabilities for 32-bit x86 operating systems for which there is no code path. Currently, this function handles Linux, Windows, and several BSDs. Mac OS, Cygwin, and Solaris are several operating systems with no code paths. Rather than add code for the unhandled operating systems, remove this function altogether. This will fix SSE detection on all recent 32-bit x86 operating systems. This completely breaks functionality on unpatched 2.2.x and earlier kernels, although there are likely no Gallium3D users on such operating systems.
* gallium: Make printing info on debug builds default offJakob Bornecrantz2010-08-151-1/+1
| | | | | | | This commit silences the printing off most of the debug information when running debug builds. The big culprits are: the tgsi sanity checker that gets run on all shaders on debug; all the options; and finaly the cpu caps printer.

It still needs a slight code massasing to integrate with the rest of gallium (namely mapping the OS_* ARCH_* defines), but I'm commiting anyway so that it is available to be used when somebody needs it.
