riastradh | rump: Move ubc_uiomove, ubc_zerorange from rumpvfs to rumpkern.
Needed by kern_ksyms.c. We could split kern_ksyms.c up into kernel-
internal interfaces and the user/kernel /dev/ksyms interface, but
there's nothing vfs-specific about ubc_uiomove and ubc_zerorange
anyway, so let's just define them in rumpkern.

chs | make rump's uvm_aio_aiodone_pages() look more like the kernel version.
fixes some more rumpy assertions.

chs | branches: 1.40.2;

chs | Move the handling of PG_PAGEOUT from uvm_aio_aiodone_pages() to
uvm_page_unbusy() so that all callers of uvm_page_unbusy() don't need to
handle this flag separately. Split out the pages part of uvm_aio_aiodone()
into uvm_aio_aiodone_pages() in rump just like in the real kernel.
In ZFS functions that can fail to copy data between the ARC and VM pages,
use uvm_aio_aiodone_pages() rather than uvm_page_unbusy() so that we can
handle these "I/O" errors. Fixes PR 55702.

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.
|
| 1.37 |
| 18-Feb-2020 |
chs | remove the aiodoned thread. I originally added this to provide a thread context
for doing page cache iodone work, but since then biodone() has changed to
hand off all iodone work to a softint thread, so we no longer need the
special-purpose aiodoned thread.
|
| 1.36 |
| 15-Jan-2020 |
ad | Merge from yamt-pagecache (after much testing):
- Reduce unnecessary page scan in putpages esp. when an object has a ton of
pages cached but only a few of them are dirty.
- Reduce the number of pmap operations by tracking page dirtiness more
precisely in uvm layer.

ad | branches: 1.35.2;
Break the global uvm_pageqlock into a per-page identity lock and a private
lock for use of the pagedaemon policy code. Discussed on tech-kern.

rumpvfs:
- ubc_uiomove: avoid the re-lock dance, since the lock is shared these days.
- uvm_aio_aiodone: acquire the lock before modifying the page flags.

Revert previous. ubc_purge() is already defined in rumpkern/vm.c
|

hannken | Add a noop wrapper for ubc_purge() to make file system tests work again.
Not really sure if this is the right way -- Antti?
|
| 1.30 |
| 16-Jun-2011 |
hannken | Rename uvm_vnp_zerorange(struct vnode *, off_t, size_t) to
ubc_zerorange(struct uvm_object *, off_t, size_t, int) changing
the first argument to an uvm_object and adding a flags argument.
Modify tmpfs_reg_resize() to zero the backing store (aobj) instead
of the vnode. Ubc_purge() no longer panics when unmounting tmpfs.
Keep uvm_vnp_zerorange() until the next kernel version bump.

| 12-Jun-2011 |
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.

pooka | Pass accurate protection info from ubc_uiomove() to the pager.
Fixes nfs{,ro}_fileio tests on at least sparc64 (and probably macppc
and other fat endian machines).
The problem was that nfs was fooled to thinking read() caused a
write fault because of VM_PROT_WRITE being unconditionally set and
therefore set NMODIFIED on a r/o file system. It is absolutely
beyond me why the test worked on i386/amd64. Incidentally, I seem
to have "misplaced" a few goats.
|

| 27-Feb-2011 |
pooka | tmpfs has two layers of uvm objects (vnode->uobj and the anon object
in tmpfs_node), so when playing with pages make sure we lock the
uvm object the pages belong to instead of the vnode's uvm object.
per test from Nicolas Joly (which I'm sure he will commit soon ;)

| 22-Feb-2011 |
pooka | Shuffle the pagedaemon algorithm a bit to record the number of
pageouts active and give up only if the pagedaemon could not free
memory and there are no outstanding pageouts.
This should fix the "out of memory" pauses reported by Mihai Chelaru
and Taylor R Campbell. Tested by copying files to and from an ffs
backed by /dev/wd0 (with and without -o log) using a 1MB rump kernel
memory limit.

fixes some more rumpy assertions.
for the busypage test, replace atf_tc_expect_fail() with atf_tc_skip()
because atf apparently has no way to expect a test program to crash.
