9 months agokernel - Wakeup threads blocked in the VM page allocator more quickly
Matthew Dillon [Thu, 27 Jun 2013 06:40:29 +0000 (23:40 -0700)]
kernel - Wakeup threads blocked in the VM page allocator more quickly

Additional tuning to changes in the way the pageout daemon and VM system
wakes up threads blocked allocating normal VM pages.  Previously the VM
system would wait for the vm_paging_target() to be reached before waking
up all waiters, and had code to try to wakeup individual threads past
the minimum.

This just didn't work very well on machines with lots of memory because
it could take quite a long time for the pageout daemon to actually reach
the vm_paging_target() (and VM load could prevent it from being reached at
all!).  Many threads could wind up being blocked indefinitely waiting for
cache and/or free page counts to reach reasonable levels.

The solution is to give the kernel time to build up a smaller number
of free+cache pages beyond the minimum, enough to give all waiting threads
a fair shot at allocating at least one page, and then simply wakeup all
the waiters.  This hysteresis is set smallish on purpose, defaulting to
a value of 16 in order to avoid holding threads blocked for excessive
periods of time.

Under heavy VM loads this creates an overlap between memory consumers and
the pageout daemon, allowing the pageout daemon to run continuously in
these situations.

* Add the vm.page_free_hysteresis sysctl, initialized to 16.  This field
  specifies a small number of pages past the minimum required for normal
  system operation before the VM system will wakeup threads blocked in the
  VM page allocator.

* Adjust tmpfs to force-free pages through the hysteresis value to reduce
  degenerate block/wakeup situations under heavy VM loads.

9 months agokernel - Sync numerous commits from FreeBSD
Matthew Dillon [Thu, 27 Jun 2013 05:42:56 +0000 (22:42 -0700)]
kernel - Sync numerous commits from FreeBSD

Synchronize a bunch of commits from the FreeBSD tree.  Commit
ids shown below are from the github FreeBSD repo.

Several commits were not synchronized, the main one being 3c7b39f7b5a4...
(Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version).
This one needs to be brought in.

One other note, not yet fixed is an issue where the driver configures
many more tags than the disk drive can actually support.  In my test
case, 255 tags for a Seagate SAS disk that really only seems to support
63.  When large numbers of commands are queued, and even sometimes when
not, the drive becomes severely inefficient for reads and writes.  Write
bandwidth that is usually in the ~30-50 MB/s range drops to ~5 MB/s.

Doing a camcontrol to reduce tags to ~16 or so seems to fix the issue.
(camcontrol tags da0 -N 16), but we need a permanent solution for this
problem.

56527fa077227f78a92c9ebc6f4f35d1bc3e1c21

  Bring in a number of mps(4) driver fixes from LSI:

    1.  Fixed timeout specification for the msleep in mps_wait_command().
        Added 30 second timeout for mps_wait_command() calls in mps_user.c.

    2.  Make sure we call mps_detach_user() from the kldunload path.

    3.  Raid Hotplug behavior change.

        The driver now removes a volume when it goes to a failed state,
        so we also need to add volume back to the OS when it goes to
        opitimal/degraded/online from failed/missing.

        Handle raid volume add and remove from the IR_Volume event.
    4.  Added some more debugging information.

    5.  Replace xpt_async(AC_LOST_DEVICE, path, NULL) with
        mpssas_rescan_target().

        This is to work around a panic in CAM that shows up when adding a
        drive with a rescan and removing another device from the driver thread
        with an AC_LOST_DEVICE async notification.

        This problem was encountered in testing with the LSI sas2ircu utility,
        which was used to create a RAID volume from physical disks.  The driver
        has to create the RAID volume target and remove the physical disk
        targets, and triggered a panic in the process.

        The CAM issue needs to be fully diagnosed and fixed, but this works
        around the issue for now.

    6.  Fix some memory initialization issues in mps_free_command().

    7.  Resolve the "devq freeze forever" issue.  This was caused by the
        internal read capacity command issued in the non-head version of the
        driver.  When the command completed with an error, the driver wasn't
        unfreezing thd device queue.

        The version in head uses the CAM infrastructure for getting the read
        capacity information, and therefore doesn't have the same issue.

    8.  Bump the version to 13.00.00.00-fbsd. (this is very close to LSI's
        internal stable driver 13.00.00.00)

ebc4133dca40744e7e5a2037e613bf403a16cc65

    Return BUS_PROBE_DEFAULT instead of BUS_PROBE_VENDOR from the mps driver
    probe routine.

    This will allow LSI to ship drivers that return BUS_PROBE_VENDOR to
