I was wondering whether such draconian steep is necessary/justified in {Linux 2.1.105}:net/core/profile.c
__initfunc(int net_profile_init(void)){ [...] printk("Evaluating net profiler cost ..."); [...] if (!(boot_cpu_data.x86_capability & 16)) { panic("Sorry, you CPU does not support tsc. I am dying...\n"); return -1;
As I think it could just disable profiling (at worst case) instead of using panic().
The box would panic on me, when trying to boot 2.1.105. I'm not sure if this above is justifed. Was the Cyrix PR-200MMX the one with broken TSC? Beside that I don't think I did enabled Halt-On-Suspend explictly.
[root@styx /root]# cat /proc/cpuinfo processor : 0 cpu family : 6 model : 6x86MX 2.5x Core/Bus Clock vendor_id : CyrixInstead stepping : 0 rev 4 fdiv_bug : no hlt_bug : no sep_bug : no f00f_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr cx8 pge cmov mmx bogomips : 166.30
Finally, a while ago there was talk about fixing the TSC stuff, there was some patches floating around. .. but are there any plans to integrate it into kernel?
