| 6 | * This include file sets up everything we need to access the load average |
|---|
| 7 | * values in the kernel in a machine independent way. First, it sets the |
|---|
| 8 | * typedef "load_avg" to be either double or long (depending on what is |
|---|
| 9 | * needed), then it defines these macros appropriately: |
|---|
| 10 | * |
|---|
| 11 | * loaddouble(la) - convert load_avg to double. |
|---|
| 12 | * intload(i) - convert integer to load_avg. |

| 15 | /* |

| 16 | * We assume that if FSCALE is defined, then avenrun and ccpu are type long. |
|---|
| 17 | * If your machine is an exception (mips, perhaps?) then make adjustments |
|---|
| 18 | * here. |
|---|
| 19 | * |
|---|
| 20 | * Defined types: load_avg for load averages, pctcpu for cpu percentages. |
