Hi, the goal of my gsoc project is to enable the system administrators to configure %CPU limits using the rctl command. So that they can for example limit a particular user to 50% cpu time. Last week I was mainly working on testing. One guy provided me access to some machines with different architectures and I successfully tested my work on amd64/9-release, amd64/current, sparc64/9-release and powerpc/9-release. I also committed some code - I reverted back to the original version of the function rctl_enforce() and I added a new function rctl_over_limit() that I use for checking if the pcpu limits are adhered to. This week I want to see how per-jail %cpu limits work. I assume that the rctl infrastructure already enables me to specify and enforce per-jail pcpu limits. So I want to see how this works in practice. I also have some small issues in my head that I want to address this week. This includes fixing some includes in my code and preventing system processes from being interrupted by rctl sleep. rudohome | help
