-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 <[email protected]>
-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.
