Sepherosa Ziehau [Thu, 7 Feb 2013 06:38:04 +0000 (14:38 +0800)]
emx: Implement multiple hardware TX queue support; disabled by default

Two notes about the multiple hardware TX queue support:

- It could only be enabled on 82571, 82572 and es2lan.  Enabling it on
  82574, whose datasheet claims multiple hardware TX queue support,
  could cause watchdog timeout when heavy TCP receiving test are
  conducted.

- It is disabled by default.  Since 82571, 82572 and es2lan only have
  one global context for TX hardware checksum and TSO, the driver will
  have to setup TX context descriptor for each packet.  Using TX context
  descriptor for each packet could cause serious transmission performance
  regression for tiny packets, see comment of following commit:
  51e6819fc2ad7cefdf830dcc9f20bcbe2af2aa52

  However, multiple hardware TX queues still could be enabled depending
  on the workload (*):
  o  TSO probably are not affected by setting up a TX context descriptor
     for each TSO packet.
  o  Stuffs do not using hardware TX checksum, e.g. IP fast forwarding.

  Multiple hardware TX queues could be enabled globally by tunable:
      hw.emx.txr=2
  Multiple hardware TX queues could be enabled on individual interface by
  tunable:
      hw.emxY.txr=2

(*) Another thought is to add per-interface metric, which indicates the
size of packets that worth hardware checksum; if the packets' size is
below that metric, software checksum is used.

functions.  GCC 4.7 will always be built.  In addition to changing the
default of WORLD_CCVER, the CCVER variable also defaults to "gcc47" now.

The variable "NO_GCC44" has been resurrected to prevent GCC 4.4 from
being built.  As noted in the UPDATING file, using this option is highly
discouraged.  GCC 4.4 is very useful in building some packages in pkgsrc

17 months agokernel - cycle vnode in cache_unlink()

kernel - cycle vnode in cache_unlink()

* cache_unlink() and cache_rename() are called by VFS's to update the
  namecache after a file deletion or rename.  cache_rename() also calls
  cache_unlink().

* Add code to this function which cycles any vnode attached to the
  namecache entry for the case where its refs are 0.  This will
  trigger VOP_INACTIVE and allow the VFS to detect file deletions.

  Generally speaking this means that VFS's no longer have to detect
  deleted files in code paths outside of VOP_INACTIVE w/regards to
  forcing a reclaim on the vnode.

* HAMMER2 now depends on this behavior.  The change in behavior allows
  HAMMER2 to do away with inode backpointers from chain structures,
  greatly simplifying the code and removing a chicken-egg dependency.

* Other VFSs (HAMMER, TMPFS, UFS) may be adjusted in the future but for
  now their file deletion code outside of VOP_INACTIVE is being left

  of things.  This was only used to detect when a vnode might have to
  be recycled but we solve that a different way by adjusting the
  kernel's cache_unlink() code.

* Revamp hammer2_inode_get().  This routine now always kmalloc()'s a new
  hammer2_inode.  In HAMMER2, the hammer2_inode structure is actually
  an indirect pointer to an underlying chain so it does not have to be
  unique.  There can multiple ip's pointing to the same chain.

* Revamp hammer2_inode_put().  The ref on ip->chain is dropped via ip->chain,
  and the (passed_chain) argument is treated separately and does not
  necessarily have to match ip->chain.  This makes hammer2_inode_put()'s API
  comparable to hammer2_inode_unlock_ex(), reducing confusion.

* Depend on adjustments to cache_unlink() and cache_rename() to detect
  vnodes which should be recycled.  This code (in the proper kernel, not
  here) now triggers a deactivation if the vnode related to the namecache
  entry has no refs, allowing HAMMER2 to detect any deletions and vrecycle()
  the vnode immediately.
