11646cd458 Handle command retries for commands originating at the mmc layer, and
ensure that all such commands have a non-zero retry count except for those
that are expected to fail (for example, because they are used to probe for
feature support).

While it is possible to pass a retry count down to the hardware driver in
the command request structure, no hardware driver currently implements any
retry logic.  The hardware doesn't know much about the context of a single
request, so it makes more sense to handle retries at a layer that does.

This adds retry loops to the mmc_wait_for_cmd() and mmc_wait_for_app_cmd()
functions.  These functions are the gateway from other code within mmc.c
to the hardware.  App commands are a sequence of two commands and a retry
has to rerun both of them in order, so it needs its own retry loop.

Retry looping is specifically NOT implemented in mmc_wait_for_request()
because it is the gateway for children on the bus, and they have to
implement their own retry logic depending on what makes sense for them.

3bfcb89de4 Add new mmap(2) flags to permit applications to request specific virtual
address alignment of mappings.
- MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n).
  Requests for n >= number of bits in a pointer or less than the size of
  a page fail with EINVAL.  This matches the API provided by NetBSD.
- MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED.  It can be used
  to optimize the chances of using large pages.  By default it will align
  the mapping on a large page boundary (the system is free to choose any
  large page size to align to that seems best for the mapping request).
  However, if the object being mapped is already using large pages, then
  it will align the virtual mapping to match the existing large pages in
  the object instead.
- Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and
  VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment.
  MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while
  MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE.
- mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than
  explicitly using VMFS_SUPER_SPACE.  All device objects are forced to
  use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively
  equivalent.

7040f30777 When the timeout clock is based on the SD clock, the timeout counter
has to be recalculated every time the SD clock frequency changes.

Also, tidy up the counter calculation... it makes no sense to calculate
a value one larger than the limit, then whine that it's too large and
truncate it to the limit.  If the BROKEN_TIMEOUT quirk is set, don't
calculate the counter at all, just set it to the limit value.

435f1b4a02 Add unmapped I/O and larger I/O support to the sa(4) driver.
We now pay attention to the maxio field in the XPT_PATH_INQ CCB,
and if it is set, propagate it up to physio via the si_iosize_max
field in the cdev structure.

We also now pay attention to the PIM_UNMAPPED capability bit in the
XPT_PATH_INQ CCB, and set the new SI_UNMAPPED cdev flag when the
underlying SIM supports unmapped I/O.

scsi_sa.c:	Add unmapped I/O support and propagate the SIM's
		maximum I/O size up.

		Adjust scsi_tape_read_write() in the same way that
		scsi_read_write() was changed to support unmapped
		I/O.  We overload the readop parameter with bits
		that tell us whether it's an unmapped I/O, and we
		need to set the CAM_DATA_BIO CCB flag.  This change
		should be backwards compatible in source and
		binary forms.

5591de079d Change the way that unmapped I/O capability is advertised.
The previous method was to set the D_UNMAPPED_IO flag in the cdevsw
for the driver.  The problem with this is that in many cases (e.g.
sa(4)) there may be some instances of the driver that can handle
unmapped I/O and some that can't.  The isp(4) driver can handle
unmapped I/O, but the esp(4) driver currently cannot.  The cdevsw
is shared among all driver instances.

So instead of setting a flag on the cdevsw, set a flag on the cdev.
This allows drivers to indicate support for unmapped I/O on a
per-instance basis.

sys/conf.h:	Remove the D_UNMAPPED_IO cdevsw flag and replace it
		with an SI_UNMAPPED cdev flag.

kern_physio.c:	Look at the cdev SI_UNMAPPED flag to determine
		whether or not a particular driver can handle
		unmapped I/O.

geom_dev.c:	Set the SI_UNMAPPED flag for all GEOM cdevs.
		Since GEOM will create a temporary mapping when
		needed, setting SI_UNMAPPED unconditionally will
		work.

		Remove the D_UNMAPPED_IO flag.

nvme_ns.c:	Set the SI_UNMAPPED flag on cdevs created here
		if NVME_UNMAPPED_BIO_SUPPORT is enabled.

vfs_aio.c:	In aio_qphysio(), check the SI_UNMAPPED flag on a
		cdev instead of the D_UNMAPPED_IO flag on the cdevsw.

sys/param.h:	Bump __FreeBSD_version to 1000045 for the switch from
		setting the D_UNMAPPED_IO flag in the cdevsw to setting
		SI_UNMAPPED in the cdev.

8544609e64 Change the queue of locks in kern_rangelock.c from holding lock requests in
the order that they arrive, to holding
(a) granted write lock requests, followed by
(b) granted read lock requests, followed by
(c) ungranted requests, in order of arrival.

This changes the stopping condition for iterating through granted locks to
see if a new request can be granted: When considering a read lock request,
we can stop iterating as soon as we see a read lock request, since anything
after that point is either a granted read lock request or a request which
has not yet been granted.  (For write lock requests, we must still compare
against all granted lock requests.)

For workloads with R parallel reads and W parallel writes, this improves
the time spent from O((R+W)^2) to O(W*(R+W)); i.e., heavy parallel-read
workloads become significantly more scalable.

No statistically significant change in buildworld time has been measured,
but synthetic tests of parallel 'dd > /dev/null' and 'openssl enc >/dev/null'
with the input file cached yield dramatic (up to 10x) improvement with high
(up to 128 processes) levels of parallelism.

c6e2041529 Export the maxio field in the CAM XPT_PATH_INQ CCB in the isp(4)
driver.

This tells consumers up the stack the maximum I/O size that the
controller can handle.

The I/O size is bounded by the number of scatter/gather segments
the controller can handle and the page size.  For an amd64 system,
it works out to around 5MB.

802b1728d8 Fix several performance related issues in the new NFS server's
DRC for NFS over TCP.
- Increase the size of the hash tables.
- Create a separate mutex for each hash list of the TCP hash table.
- Single thread the code that deletes stale cache entries.
- Add a tunable called vfs.nfsd.tcphighwater, which can be increased
  to allow the cache to grow larger, avoiding the overhead of frequent
  scans to delete stale cache entries.
  (The default value will result in frequent scans to delete stale cache
   entries, analagous to what the pre-patched code does.)
- Add a tunable called vfs.nfsd.cachetcp that can be used to disable
  DRC caching for NFS over TCP, since the old NFS server didn't DRC cache TCP.
It also adjusts the size of nfsrc_floodlevel dynamically, so that it is
always greater than vfs.nfsd.tcphighwater.

For UDP the algorithm remains the same as the pre-patched code, but the
tunable vfs.nfsd.udphighwater can be used to allow the cache to grow
larger and reduce the overhead caused by frequent scans for stale entries.
UDP also uses a larger hash table size than the pre-patched code.
