Branch: rmind-uvmplock
Description: Reorganize locking in UVM and improve x86 pmap(9)
Status: Active
Start Date: 15 March 2010
End Date:
Base Tag: rmind-uvmplock-base
Maintainer: Mindaugas Rasiukevicius <rmind@netbsd.org>
Scope: Kernel
Notes: Goals:
- Reorganize locking in UVM and serialize pmap(9) operations
on same page(s). New lock order: [vmpage-lock] -> pmap-lock.
Based on the patch from ad@.
- Simplify locking in pmap(9) modules by removing P->V locking.
- Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
to share locks among UVM objects where necessary.
- Rewrite and optimize x86 TLB shootdown code.
- Unify /dev/mem et al in MI code and provide required locking.
Future work:
- Optimize pmap_remove() with tracking in struct vm_map_entry.
Branch: rpaulo-netinet-merge-pcb
Description: merge in6pcb with inpcb
