Hello all. I've done a fair amount of research in order to try and solve the issue of my HyperThreading not getting enabled. I, however, have not gotten anywhere with it.
I've got a 3.0GHz P4 with HyperThreading (Intel 531 processor for those of you who know of the Intel Processor Numbers) - kernel 2.6.13. I've enabled SMP and the HT scheduling option in the kernel config along with ACPI as I was told that it's a requirement in order to get HT to work. Yes, HT is enabled in BIOS. After compiling, installing, rebooting, etc, I don't see any changes. This is what /proc/cpuinfo shows: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 1 cpu MHz : 2993.004 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 3 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 cid cx16 xtpr bogomips : 5993.61 I've been reading about CPU Enumeration something-or-other but I've gathered that that option has been removed from the menus since the earlier 2.6 kernels. I'm not sure what bearing it would have on my current situation. I did recall that I had ACPI turned off in BIOS which logically should be on for the kernel to get any hardware backing but enabling it caused my keyboard to work up until a few seconds after the login prompt comes up. After that, it locks up (LEDs don't toggle). Everything else appears to work but I have to hard reboot the system. I've since turned ACPI support off in BIOS. A related power management issue that I should mention is that I used to use APM on my old mobo and with no other sub options enabled, it would cause my system to auto power off at the end of runlevel 0. Neither APM nor ACPI does this for me now (I assume because APM isn't used and ACPI is off and a lil misconfigged on my end, it would seem). Something tells me that all of this is related somehow. Anyway, any help would be greatly appreciated :) I seem to be having a rather unique experience as I've read several accounts of HT issues but all ended up resolved much easier than this has been going. Other information I know that I'll be asked for: Intel 865PE Northbridge Intel ICH5 Southbridge Latest BIOS correct memory installation Thanks! -Statux
