It looks like the kernel uses the wrong value. IBM says that the
secondary number is the IFL capability (lower is faster).
Hmm, that number is retrieved by this code snipped:
rc = stsi(info, 1, 2, 2);
if (rc == -ENOSYS)
goto out;
rc = 0;
*capability = info-capability;
struct sysinfo_1_2_2 {
char format;
char reserved_0[1];
unsigned short acc_offset;
char reserved_1[24];
unsigned int secondary_capability;
unsigned int capability;
unsigned short cpus_total;
unsigned short cpus_configured;
unsigned short cpus_standby;
unsigned short cpus_reserved;
unsigned short adjustment[0];
};
It always reports the primary capability. We'll investigate.
