Hi,
A few days ago I had to replace my Motherboard and CPU. Now I want to make use
of the new CPUs features.
Old CPU: Intel Pentium 4
New CPU: Intel Pentium 4 (Prescott)
# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Pentium(R) 4 CPU 3.20GHz
stepping : 3
cpu MHz : 3209.105
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 5
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm pni monitor
ds_cpl est cid cx16 xtpr
bogomips : 6340.60
So I'm planning to do something along these lines:
1) Change CFLAGS in make.conf
Old: CFLAGS="-O2 -mcpu=pentium4 -march=pentium4 -fomit-frame-pointer
-pipe"
New: CFLAGS="-O2 -march=prescott -mmmx -msse -msse2 --pipe
-fomit-frame-pointer"
2) emerge --emptytree system
3) emerge --emptytree world
Would that be the right CFLAGS for this CPU? And would it be the right
procedure to get my system "up to date" with my new CPU?
Regards,
