Hello Vasily,
I've encountered the exactly same problem. The following patch
fix the problem.

Hello, Naoaki.
Thanks for your answers.
Tomorrow I was sure, that all conditions, you mentioned, were fulfilled.
But today I decided to repeat all procedure from the very beginning.
And now it works ok. So, I guess, it was my trouble!
Now I'm trying to use memory controller.
But after sucessfull patching 2.6.14 original kernel with mem_rc-f0.4
(and ckrm_core pathes before it, of course), the compilation doesn't

Can anybody tell me the reason?
Thanks.

That's my way to get CPU controller work:
I just run task with infinite loop in backgroung, in order to load CPU.
Create 2 classes, and put there the same application (other process,
of cource)
dhcp0-138 ~ # ls /config/ckrm/
attrib class1 class2 config members shares stats
dhcp0-138 ~ # cat /config/ckrm/shares
res=numtasks,guarantee=-2,limit=-2,total_guarantee=100,max_limit=100
res=cpu,guarantee=100,limit=-2,total_guarantee=100,max_limit=-2
dhcp0-138 ~ # cat /config/ckrm/class1/shares
res=numtasks,guarantee=-2,limit=-2,total_guarantee=100,max_limit=100
res=cpu,guarantee=10,limit=-2,total_guarantee=100,max_limit=-2
dhcp0-138 ~ # cat /config/ckrm/class2/shares
res=numtasks,guarantee=-2,limit=-2,total_guarantee=100,max_limit=100
res=cpu,guarantee=90,limit=-2,total_guarantee=100,max_limit=-2
dhcp0-138 ~ # top
21257 root 25 0 1308 252 200 R 33.2 0.0 3:37.82 a.out
21258 root 25 0 1304 248 200 R 33.2 0.0 3:37.34 a.out
21238 root 25 0 1304 252 200 R 32.6 0.0 5:41.24 a.out
^^^
So, I can't see any propotionality...
ctop shoes strange info:
ClassName: cpu load (%)
-------------------------------|--------------|
ckrm : 0.00
class1 : 0.00
class2 : 0.00
this is f0.4 series.
Can you comment this situation, please?
Even if all of the a.out belong to the default class, ctop might
show as following:
ClassName: cpu load (%)
-------------------------------|--------------|
ckrm : 95.00 <-- Default class's load
class1 : 0.00
class2 : 0.00
Only one thing I can come up with is kernel misconfiguration.
Could you check if CONFIG_CPU_RC=y is defined in your .config file?
In my intention, it is automatically defined by selecting
CONFIG_CKRM_RES_CPU, though.
- cited from init/Kconfig
config CKRM_RES_CPU
bool "CPU Resource Controller"
select CPU_RC
depends on CKRM
default y
help
Provides a CPU Resource Controller for CKRM.
Say N if unsure, Y to use the feature.
Thanks,
