Hi there,
Has anyone known about the background information about
the following change?
The PSCHED_JSCALE in the net/sched/sch_api.c is defined in the include/net/pkt_sched.h. If I set HZ to 1000 - PSCHED_JSCALE is 0 - what would happen?
#if HZ == 100 #define PSCHED_JSCALE 13 #elif HZ == 1024 #define PSCHED_JSCALE 10 #else #define PSCHED_JSCALE 0 #endif The code is updated in 2.4.27 as follows. The PSCHED_JSCALE becomes 10 in this case. What problems would it fix? Or what behaivior would change?
#if HZ < 96 #define PSCHED_JSCALE 14 #elif HZ >= 96 && HZ < 192 #define PSCHED_JSCALE 13 #elif HZ >= 192 && HZ < 384 #define PSCHED_JSCALE 12 #elif HZ >= 384 && HZ < 768 #define PSCHED_JSCALE 11 #elif HZ >= 768 #define PSCHED_JSCALE 10 #endif
