Mario, Ok, I added a hard drive, installed Debian Lenny and was able to follow the instructions here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI I built three kernels, using processor family selections of 586/K5/5x86/6x86/6x86mx, even though the instructions said it was incompatible with smp, Pentium-Pro (which seemed to be auto-detected) and core 2 / newer Xeon. Building and rebooting with the built kernel in all cases reported 1 processor. In what I found on-line it should actually report 4 processors (2 core / 2 logical). I don't see that any of the other processor selections match up. The other options under menuconfig are: 386 486 586/K5/5x86/6x86/6x86MX Pentium-Classic Pentium-MMX Pentium-Pro Pentium-II/Celeron(pre-Coppermine) Pentium-III/Celeron(Coppermine)/Pentium-III Xeon Pentium M Core 2/newer xeon Pentium-4/Celeron(P4-based)/Pentium-4 M/older Xeon K6/K6-II/K6-III Athlon/Duron/K7 Opteron/Athlon64/Hammer/K8 Crusoe Efficeon Winchip-C6 Winchip-2 Winchip-2A/Winchip-3 GeodeGX1 Geode GX/LX CyrixIII/VIA-C3 VIA C3-2 (Nehemiah) VIA C7 I am still using the 2.6.22 kernel. Is it possible the kernel is just too old for the atom 330? I have not tried gentoo as at this point all I want is a kernel that recognizes more than one processor. Making it more efficient is just a bonus, and I don't know enough about building kernels to translate the setting to those required under gentoo. Any ideas what I should try next? Regards, Eric I guess the P6 should be generic enough... I searched a lot but no definite answer, other than the Atom uses SSE2, so "P6" should have enough performance and compatibility with all architectures (the default on many builds). These are important ((only?)) to make performance optimisations for a specific architecture (tailor-made) and Atom is very limited in all aspects, not sure if there is a setting for that yet. but P6 setting was used on other architectures taht had not their specific tag at that time. |
