SMPng Progress Update ===================== Contact: freebsd-smp@FreeBSD.org Date: January 12th, 2002 URL: http://www.FreeBSD.org/smp/ Recent Progress --------------- - mb_alloc(): Bosko Milekic has been doing some cleaning up on the mbuf and cluster allocator. The code has been in the tree and pretty stable for about 7 or 8 months now. - fd locking patches: Alfred Perlstein is working on getting make world to build with regards to locking the fd code. A recent patch can be found at: http://people.freebsd.org/~alfred/fd.diff - icu_lock: John Baldwin added the icu_lock in the pci interrupt code up a layer in order to resolve locking problems during low-level console init. (p4) - kernel preemption: p4 work by John Baldwin - TLB shootdowns: Peter Wemm has been working on pmap cleanups for x86 SMP TLB shootdowns. To do ----- - mb_alloc(): Wait and see what happens with Jeff Roberson's general purpose allocator and how it will affect mbuf and cluster allocation. - proc lockdown: Continued work in the jhb proc lock tree in perforce. - Kernel preemption - Making ktrace handle requests asynchronously via a kernel process - Determining affinity rules; waiting on KSEs to be implemented in full. - Discuss and decide how this will affect interrupt latency issues - Look at the linux per-cpu runqueues further - Determining the next steps for locking down the network stack. - fd locking: modify the code if needed to please -smp@ and commit - Continue work on tlb shootdowns. - Check SMPng web page for more information on TODOs.
