From 14581afb474552716c02ca15220ca7050123c375 Mon Sep 17 00:00:00 2001 From: Benjamin Close Date: Thu, 26 Feb 2009 17:32:10 +1030 Subject: [PATCH] xfree86: correctly define barriers for FreeBSD amd64 Previously when compiling on freebsd amd64 we'd end up at xi86 block (line 1315) which would define mem_barrier and write_mem_barrier to be NOP's. Instead they should be valid, as per the linux amd64 setup. This stops the hangs experienced by many when using the nv driver which would hang due to out of order dma requests as noticed in http://bugs.freedesktop.org/show_bug.cgi?id=3168 Signed-off-by: Benjamin Close --- hw/xfree86/common/compiler.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/xfree86/common/compiler.h b/hw/xfree86/common/compiler.h index 40b463efb..2ef95d8d3 100644 --- a/hw/xfree86/common/compiler.h +++ b/hw/xfree86/common/compiler.h @@ -462,7 +462,7 @@ extern _X_EXPORT unsigned int inb(unsigned long port); extern _X_EXPORT unsigned int inw(unsigned long port); extern _X_EXPORT unsigned int inl(unsigned long port); -# elif defined(linux) && defined(__amd64__) +# elif (defined(linux) || defined(__FreeBSD__)) && defined(__amd64__) # include
