Re: sched: Consequences of integrating the Per Entity Load Tracking Metric into the Load Balancer

2013-01-08 Thread Preeti U Murthy
Here comes the point of making both load balancing and wake up balance(select_idle_sibling) co operative. How about we always schedule the woken up task on the prev_cpu? This seems more sensible considering load balancing considers blocked load as being a part of the load of cpu

We should be able to configure QEMU for cross compiling it for ARM64 host. This patch only tries to make sure that the configure step falls through and atleast QEMU cross-compilation starts. The rationale behind cpu=aarch64 naming (as commented by Peter Maydell): For the target architecture name

Hi Mike, Thank you very much for such a clear and comprehensive explanation. So when I put together the problem and the proposed solution pieces in the current scheduler scalability,the following was what I found: 1. select_idle_sibling() is needed as an agent to correctly find the right cpu fo
