INST_CHKA_LDC_ALAT.INT | The number of all advanced check load (chk.a) and check |
| load (ld.c) instructions that reach retirement. Counts only |
| retired integer instructions. |
INST_FAILED_CHKA_LDC_ALAT.FP | The number of failed advanced check load (chk.a) and |
| check load (ld.c) instructions that reach retirement. Counts |
| only failed |
INST_FAILED_CHKA_LDC_ALAT.INT | The number of failed advanced check load (chk.a) and |
| check load (ld.c) instructions that reach retirement. Counts |
| only failed integer instructions. |
Percent data speculation miss | Percentage of retired chk.a /ld.c instructions that failed. |
Percent float advanced check load | Percentage of |
| instructions, with respect to all chk.a /ld.c instructions. |
Percent integer advanced check load | Percentage of retired chk.a /ld.c integer instructions that |
| failed. |
Percent failed float advanced check | Percentage of |
load | with respect to all chk.a /ld.c failed instructions. |
Percent integer advanced check load | Percentage of integer chk.a /ld.c instructions with respect |
| to all chk.a /ld.c instructions. |
Percent float ALAT miss | Percentage of |
| incurred by instructions accessing the ALAT. |
Percent integer ALAT miss | Percentage of integer components in all the misses incurred |
| by instructions accessing the ALAT. |
Advanced check load per kinst | The number of data speculation events per 1000 retired |
| instructions. |
Failed advanced check load per kinst | The number of data speculation fail events per 1000 retired |
| instructions. |
% of cycles lost due to stalls | Percent of cycles lost due to stalls. |
% Core cycles due to this thread | This indicates the percentage of available processor cycles |
| that the measured process consumed. The other processor |
| cycles were consumed by other process(es) running in the |
| core's other hyperthread or were lost to HyperThreading |
| overhead. |

The number of variable clock cycles. (When charge rationing is on, the period of the cycle could change.) It does not count cycles when the CPU is in low power mode.
When HyperThreading is on, this is the number of variable clock cycles used by the hyperthread of a specific process.
The number of variable clock cycles used by both hyperthreads. Available only when HyperThreading is on.
The number of retired instructions excluding
Number of Backend cycles stalled.
Any ALAT failed advanced check load (chk.a) or check load (ld.c).
ALAT failed floating point chk.a ld.c. ALAT failed integer chk.a ld.c.
Any ALAT chk.a ld.c.
