svn commit: r322485 - head/sys/dev/hyperv/netvsc

[Sepherosa Ziehau]

Author: sephe
Date: Mon Aug 14 05:40:52 2017
New Revision: 322485
URL: https://svnweb.freebsd.org/changeset/base/322485

Log:
  hyperv/hn: Fix/enhance receiving path when VF is activated.
  
  - Update hn(4)'s stats properly for non-transparent mode VF.
  - Allow BPF tapping to hn(4) for non-transparent mode VF.
  - Don't setup mbuf hash, if 'options RSS' is set.
In Azure, when VF is activated, TCP SYN and SYN|ACK go through hn(4)
while the rest of segments and ACKs belonging to the same TCP 4-tuple
go through the VF.  So don't setup mbuf hash, if a VF is activated
and 'options RSS' is not enabled.  hn(4) and the VF may use neither
the same RSS hash key nor the same RSS hash function, so the hash
value for packets belonging to the same flow could be different!
  - Disable LRO.
hn(4) will only receive broadcast packets, multicast packets, TCP
SYN and SYN|ACK (in Azure), LRO is useless for these packet types.
For non-transparent, we definitely _cannot_ enable LRO at all, since
the LRO flush will use hn(4) as the receiving interface; i.e.
hn_ifp->if_input(hn_ifp, m).
  
  While I'm here, remove unapplied comment and minor style change.

New Revision: 322479

Log:
  Add hinted attachment for non-FDT systems.  Also, print a message if
  setting up the timer fails, because on some types of chips that's the
  first attempt to access the device.  If the chip is missing/non-responsive
  then you'd get a driver that attached and didn't register the rtc, with
  no clue about why.  On other chip types there are inits that come before
  timer setup, and they already print messages about errors.

svn commit: r322477 - in head/sys: dev/iicbus modules/i2c modules/i2c/s35390a

[Ian Lepore]

Author: ian
Date: Mon Aug 14 00:00:24 2017
New Revision: 322477
URL: https://svnweb.freebsd.org/changeset/base/322477

Log:
  Minor fixes and enhancements for the s35390a i2c RTC driver...
  
  - Add FDT probe code.
  - Do i2c transfers with exclusive bus ownership.
  - Use config_intrhook_oneshot() to defer chip setup because some i2c
busses can't do transfers without interrupts.
  - Add a detach() routine.
  - Add to module build.

svn commit: r322473 - in head/sys: conf dev/iicbus modules/i2c modules/i2c/ds13rtc

[Ian Lepore]

Author: ian
Date: Sun Aug 13 21:02:40 2017
New Revision: 322473
URL: https://svnweb.freebsd.org/changeset/base/322473

Log:
  Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.
  
  This driver supports only basic timekeeping functionality.  It completely
  replaces the ds133x driver.  It can also replace the ds1374 driver, but that
  will take a few other changes in MIPS code and config, and will be committed
  separately.  It does NOT replace the existing ds1307 driver, which provides
  access to some of the extended features on the 1307 chip, such as controlling
  the square wave output signal.  If both ds1307 and ds13rtc drivers are
  present, the ds1307 driver will outbid and win control of the device.
  
  This driver can be configured with FDT data, or by using hints on non-FDT
  systems.  In addition to the standard hints for i2c devices, it requires
  a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
  (i.e., the same format as FDT compat strings).

svn commit: r322470 - head/sys/arm64/arm64

[Andrew Turner]

Author: andrew
Date: Sun Aug 13 18:54:51 2017
New Revision: 322470
URL: https://svnweb.freebsd.org/changeset/base/322470

Log:
  Add support for multiple GICv3 ITS devices. For this we add sc_irq_base
  and sc_irq_length to the softc to handle the base number of IRQs available,
  make gicv3_get_nirqs return the number of available interrupt IDs, and
  limit which CPUs we send interrupts to based on the numa domain.
  
  The last point is only strictly needed on a dual socket ThunderX where we
  are unable to send MSI/MSI-X interrupts between sockets.

Log:
  Add config_intrhook_oneshot(): schedule an intrhook function and unregister
  it automatically after it runs.
  
  The config_intrhook mechanism allows a driver to stall the boot process
  until device(s) required for booting are available, by not allowing system
  inits to proceed until all intrhook functions have been unregistered.
  Virtually all existing code simply unregisters from within the hook function
  when it gets called.
  
  This new function makes that common usage more convenient. Instead of
  allocating and filling in a struct, passing it to a function that might (in
  theory) fail, and checking the return code, now a driver can simply call
  this cannot-fail routine, passing just the intrhook function and its arg.

svn commit: r322464 - head/sys/geom/journal

[Kirk McKusick]

Author: mckusick

New Revision: 322464

Log:
  When read requests are sent from a filesystem running above g_journal,
  the g_journal level needs to check whether it is holding a newer
  copy of the block than that which exists on the disk. If so, it
  needs to return its copy. If not, it should pass the request down
  to the disk to fulfill. It currently considers six queues:
  
  0) delayed queue,
  1) unsent (current queue),
  2) in-flight to the journal (flush queue),
  3) active journal (active queue),
  4) inactive journal (inactive queue), and
  5) inflight to the disk (copy queue).
  
  Checking on two of these queues is unnecessary:
  
  0) The delayed requests should not be used for reads because they
 have not yet been entered into the journal, so their value should
 reflect the disk contents, not the future contents that are not
 yet committed.
  
  2) Because all the bio's in the flush queue are also found on the
 active queue, there is no need to inspect the flush queue for
 reads since they will be found when searching the active queue.

svn commit: r322459 - in head/sys: kern sys

[Alan Cox]

Author: alc
Date: Sun Aug 13 16:39:49 2017
New Revision: 322459
URL: https://svnweb.freebsd.org/changeset/base/322459

Log:
  The *_meta_* functions include a radix parameter, a blk parameter, and
  another parameter that identifies a starting point in the memory address
  block.  Radix is a power of two, blk is a multiple of radix, and the
  starting point is in the range [blk, blk+radix), so that blk can always be
  computed from the other two.  This change drops the blk parameter from the
  meta functions and computes it instead.  (On amd64, for example, this
  change reduces subr_blist.o's text size by 7%.)
  
  It also makes the radix parameters unsigned to address concerns that the
  calculation of '-radix' might overflow without the -fwrapv option.  (See
  https://reviews.freebsd.org/D11819.)
