/* * Top - a top users display for Berkeley Unix * * Defines required to access load average figures. * * This include file sets up everything we need to access the load average * values in the kernel in a machine independent way. First, it sets the * typedef "load_avg" to be either double or long (depending on what is * needed), then it defines these macros appropriately: * * loaddouble(la) - convert load_avg to double. * intload(i) - convert integer to load_avg. */ /* * We assume that if FSCALE is defined, then avenrun and ccpu are type long. * If your machine is an exception (mips, perhaps?) then make adjustments * here. * * Defined types: load_avg for load averages, pctcpu for cpu percentages. */ #ifdef mips # include <sys/fixpoint.h> # if defined(FBITS) && !defined(FSCALE) # define FSCALE (1 << FBITS) /* mips */ # endif #endif #ifdef FSCALE # define FIXED_LOADAVG FSCALE # define FIXED_PCTCPU FSCALE #endif #ifdef ibm032 # undef FIXED_LOADAVG # undef FIXED_PCTCPU # define FIXED_PCTCPU PCT_SCALE #endif #ifdef FIXED_PCTCPU typedef long pctcpu; # define pctdouble(p) ((double)(p) / FIXED_PCTCPU) #else typedef double pctcpu; # define pctdouble(p) (p) #endif #ifdef FIXED_LOADAVG typedef long load_avg; # define loaddouble(la) ((double)(la) / FIXED_LOADAVG) # define intload(i) ((int)((i) * FIXED_LOADAVG)) #else typedef double load_avg; # define loaddouble(la) (la) # define intload(i) ((double)(i)) #endif
