[PATCH] cpuid x87 bit on AMD falsely marked as PNI
http://bugme.osdl.org/show_bug.cgi?id=4426
vendor_id : AuthenticAMD
cpu family : 6
model : 10
model name : AMD Athlon(tm) XP
stepping : 0
cpu MHz : 2204.807
<snipped>
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 mmx fxsr sse pni syscall mmxext 3dnowext 3dnow
bogomips : 4358.14
We're marking bit 0 of extended function 0x80000001 cpuid as PNI support on
AMD processors, when it actually denotes x87 FPU present. Patch for i386
and x86_64 below.
