Hi, |

A few days ago I had to replace my Motherboard and CPU. Now I want to make use |
4 |
of the new CPUs features. |
5 |
Old CPU: Intel Pentium 4 |
6 |
New CPU: Intel Pentium 4 (Prescott) |
7 |
# cat /proc/cpuinfo |
8 |
processor : 0 |
9 |
vendor_id : GenuineIntel |
10 |
cpu family : 15 |
11 |
model : 4 |
12 |
model name : Intel(R) Pentium(R) 4 CPU 3.20GHz |
13 |
stepping : 3 |
14 |
cpu MHz : 3209.105 |
15 |
cache size : 2048 KB |
16 |
fdiv_bug : no |
17 |
hlt_bug : no |
18 |
f00f_bug : no |
19 |
coma_bug : no |
20 |
fpu : yes |
21 |
fpu_exception : yes |
22 |
cpuid level : 5 |
23 |
wp : yes |
24 |
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca |
25 |
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm pni monitor |
26 |
ds_cpl est cid cx16 xtpr |
27 |
bogomips : 6340.60 |
28 |
|
29 |
So I'm planning to do something along these lines: |
30 |
|
31 |
1) Change CFLAGS in make.conf |
32 |
Old: CFLAGS="-O2 -mcpu=pentium4 -march=pentium4 -fomit-frame-pointer -pipe" |
33 |
New: CFLAGS="-O2 -march=prescott -mmmx -msse -msse2 --pipe |
34 |
-fomit-frame-pointer" |
35 |
2) emerge --emptytree system |
36 |
3) emerge --emptytree world |
37 |
|
38 |
Would that be the right CFLAGS for this CPU? And would it be the right |
39 |
procedure to get my system "up to date" with my new CPU? |
40 |
|
41 |
Regards, |
42 |
