Hi Daniel,
Thanks for your comments.
I will not change public ABI nor break RPC.
I wonder if you would agree with extend virHostCPUGetInfoPopulateLinux to get l3 cache
size ?
Such as:
virHostCPUGetInfoPopulateLinux(FILE *cpuinfo,
virArch arch,
unsigned int *cpus,
unsigned int *mhz,
unsigned int *nodes,
unsigned int *sockets,
unsigned int *cores,
unsigned int *threads,
unsigned int *l3_cache) ←---------
virHostCPUGetInfoPopulateLinux is doing parsing /proc/cpuinfo , so I think it’s the best
way to get l3 cache size.
cat /proc/cpuinfo
/proc/cpuinfo is a pretty awful file because its contents are completely
different on every linux architecture. It would be preferrable to get
the cache sizes from /sys/devices/system/cpu/* if possible.
Regards,
Daniel
