From da1c40260d8cb49eacbb6c394198dc37e020e75a Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Thu, 26 Nov 2009 11:15:08 +0000 Subject: llvmpipe: Update/correct CPU requirements. There are no hard requirements at the moment. We don't really emit any sse3 yet. Just some ssse3. Thanks to Roland for spotting these incorrections. --- src/gallium/drivers/llvmpipe/README | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'src/gallium/drivers/llvmpipe/README') diff --git a/src/gallium/drivers/llvmpipe/README b/src/gallium/drivers/llvmpipe/README index 478e0139c8..0c3f00fd58 100644 --- a/src/gallium/drivers/llvmpipe/README +++ b/src/gallium/drivers/llvmpipe/README @@ -51,9 +51,13 @@ Requirements - Linux - - A x86 or amd64 processor with support for sse2, sse3, and sse4.1 SIMD - instructions.
