OK, so I got back on the machine and I do have it in make.conf here: |
26 |
|
27 |
mark@c2RAID6 ~ $ cat /etc/portage/make.conf | grep CPU_FLAGS |
28 |
#CPU_FLAGS_X86="mmx sse sse2 ssse3" |
29 |
CPU_FLAGS_X86="aes mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" |
30 |
mark@c2RAID6 ~ $ |
31 |
|
32 |
and I guess like you I do not see it in /proc/cpuinfo: |
33 |
|
34 |
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge |
35 |
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe |

It appears more study is needed. I've had no problems, as best I can |
43 |
tell, with ffmpeg and these settings. |
