This is vs 1.9.3-rc2.1, utils 0.30.195.
# vcontext --create -- \
vsched --fill-rate 1001 \
--interval 1002 \
--tokens 1003 \
--tokens_min 1004 \
--tokens_max 1005 \
--cpu_mask 0 -- sleep 1000
New security context is 49153
vsched: WARNING: the '--cpu_mask' parameter is deprecated and will not have any effect
... now in another shell:
# cat /proc/virtual/49153/sched
Token: 1001
FillRate: 115
Interval: 1001
TokensMin: 1003
TokensMax: 1004
PrioBias: 0
cpu 0: 0 0 0
cpu 1: 0 0 0
cpu 2: 1 0 0
cpu 3: 0 0 0
Somehow these numbers don't match.
I see in include/linux/vserver/sched.h
struct vcmd_set_sched_v2 {
int32_t fill_rate;
int32_t interval;
int32_t tokens;
int32_t tokens_min;
int32_t tokens_max;
uint64_t cpu_mask;
};
struct vcmd_set_sched_v3 {
uint32_t set_mask;
int32_t fill_rate;
int32_t interval;
int32_t tokens;
int32_t tokens_min;
int32_t tokens_max;
int32_t priority_bias;
};
And it looks like utils pass v3 while the kernel treats it as v2 and so my
fill_rate becomes set_mask, but I can't figure out where the actual
problem is...
HTH a little bit,
Grisha
