ad | Go back to freeing struct vm_anon one by one. There may have been an
advantage circa ~2008 but there isn't now.
|
| 1.31 |
| 23-Feb-2020 |
ad | UVM locking changes, proposed on tech-kern:
- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart. v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap. Others to follow later.

rmind | branches: 1.30.54; 1.30.60;
- Rework uvm_anfree() into uvm_anon_freelst(), which always drops the lock.
- Free anons in uvm_anon_freelst() without lock held.
- Mechanic sync to unused loaning code.

rmind | Fix uvmplock regression - a lock against oneself case in amap_swap_off().
Happens since amap is NULL in uvmfault_anonget(), so uvmfault_unlockall()
keeps anon locked, when it should unlock it.

rmind | Welcome to 5.99.53! Merge rmind-uvmplock branch:
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

for details, see discussion filed in the PR database.
uvm_anon_release: a new function to free anon-owned PG_RELEASED page.
uvm_anfree: we can't wait for the page here because the caller might hold
amap lock. instead, just mark the page as PG_RELEASED.
who unbusy the page should check the PG_RELEASED.
uvm_aio_aiodone: uvm_anon_release() instead of uvm_page_unbusy()
if appropriate.
uvmfault_anonget: check PG_RELEASED.

fields (add macros to amap api as needed)

mrg | initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the UVM kernel code portion.
this will be KNF'd shortly. :-)
