| need to fix hugetlbfs to allow holey files (for numactl) |
| numademo numbers seem to be unstable. investigate. |
| need more test programs |
| |
| Replace unreliable counters in numamon with supported ones. |
| According to Alex Tomas: |
| seems ht bus utilization can be found by |
| (cmd+data+bufrelease / cmd+data+bufrelease+nop) |
| according to chm in codeanalyst. |
| quote from .chm: |
| Buses 0,1, 2 ?The number of Dwords transmitted (or unused, in the case |
| +of Nops) on the outgoing side of the HyperTransport links. The sum of all |
| +four sub-events (all four unit mask bits set) directly reflects the |
| +transmission rate of the link. Calculate link utilization by dividing the |
| +combined Command, Data, and Buffer Release count (unit mask 07h) by that |
| +value plus the Nop count (unit mask 08h). Bandwi |
| dth in terms of bytes per unit-time for any one component, or |
| +combination of components, is calculated by multiplying the count by four and |
| +dividing by elapsed time. |
| and |
| 0xE9 is also documented |
