search for: fxsr

Some debugging tools don't like if a code uses unitialized variables. The code in cpu.c uses the value of fxsr.buff[50], so it makes sense to explicitely initialize it (because fxsave can fail to do it). -------------- next part -------------- A non-text attachment was scrubbed...

Explanation of changes in this patch: 1) 'CALLBACK' was changed to 'WINAPI' because the signature of an unhandled exception filter is LONG (WINAPI *unhandled_func)(struct _EXCEPTION_POINTERS); 2) The code if(info->ia32.fxsr || info->ia32.sse || info->ia32.sse2) { [...] } was replaced by if(info->ia32.sse) { [...] } else info->ia32.fxsr = info->ia32.sse = [...] = false; Reason: there's no point to test OS SSE support if SSE (SSE1) is not supported by CPU.

Hi gang! At work I have a DL320 G2 machine I use as my desktop (I know, weird!...). Back when I ran RHEL WS 2.1 on it, it always ran a SMP kernel because it has a HypterThread capable processor. When I installed (fresh from scratch) Centos 4.4 on it a while back, though, Centos installed only the UP kernel. I've looked in the BIOS for settings to enable/disable HT support and I don't
