searched on google but found for other fones... guessing they wont be compatible with our blade..

something like this??

Unless I'm seriously misunderstanding the kernel CM7 uses it shouldn't be a major issue adding BFQ/BFS, the question is that is BFS relevant for a low end droid device? sio/ondemand/smartass have slaughtered every BFS implementation i've come across on my blade

I noticed CM7 becoming sluggish the last time BFS was removed from the kernel.

yup your misunderstanding is between two diff things viz. I/O scheduler and cpu scheduler..... BFQ is budget fair queueing(for i/o i.e sd card and internal memory reading and writing fashion) and BFS is brain F*** scheduler(related to cpu where different taks are queued for the cpu to process them).. u can switch between diff I\O schedulers but not cpu schedulers..cpu scheduler is built in inside a kernel and can be changed only with a kernel change...anyone correct me if am wrong

I noticed CM7 becoming sluggish the last time BFS was removed from the kernel.

still some googling says that cm has a bfs scheduler..but not really sure... there are kernels available but sadly not for our device..

Might be worthy to ask TomG about this into why BFS was removed? :)

It was removed by Jacob AFAIK (For what look from the changelog like a stupid/wrong reason) not TomG (and it was when CM used 2.6.32)

(Its still in somewhat active development)

Also chances (if there is a scheduler bug / performance issue) of getting it fixed is far far higher than getting it fixed by the maintainer of the CFS scheduler or Qualcomm or Google.

#ck on oftc is very helpful
