5 years agokernel - Refactor tty clist code
Matthew Dillon [Thu, 4 Oct 2018 21:37:12 +0000 (14:37 -0700)]

  a single linear buffer and a FIFO mechanism.

* The linear buffer just uses 16-bit elements in order to record

5 years agokernel - Refactor tty_token, fix SMP performance issues
Matthew Dillon [Thu, 4 Oct 2018 17:22:35 +0000 (10:22 -0700)]
kernel - Refactor tty_token, fix SMP performance issues

* Remove most uses of tty_token in favor of per-tty tp->t_token.
  This is particularly important for removing bottlenecks related to PTYs,
  which are used all over the place.  tty_token remains in a few places
  managing overall registration and global list manipulation.

* tty structures are now required to be persistent.  Implement a sepearate
  ttyinit() function.  Continue to allow ttyregister() and ttyunregister()
  calls, but these no longer presume destruction of the structure.

* Refactor ttymalloc() to take a **tty pointer and interlock allocations.
  Allocations are intended to be one-time.  ttymalloc() only requires the
  tty_token for initial allocations.

* Remove all critical section use that was combined with tty_token and
  tp->t_token.  Leave only the tokens.  The critical sections were
  hold-overs going all the way back to pre-SMP days.

* syscons now gets its own token, vga_token.  The ISA VGA code and
  the framebuffer code also now use this token instead of tty_token.

* The keyboard subsystem now uses kbd_token instead of tty_token.

* A few remaining serial-like devices (snp, nmdm) also get their own
  tokens, as well as use the now required tp->t_token.

* Remove use of tty_token in the session management code.  This fixes
  a niggling performance path since sessions almost universally go
  hand-in-hand with fork/exec/exit sequences.  Instead we use the
  already-existing per-hash session token.

5 years agokernel - Remove duplicate TRIM, only trim with the 'trim' mount opt
Matthew Dillon [Tue, 2 Oct 2018 04:12:28 +0000 (21:12 -0700)]
kernel - Remove duplicate TRIM, only trim with the 'trim' mount opt

* ffs_blkfree_cg() was improperly issuing a synchronous
  VOP_FREEBLKS() on the underlying device.  This issues a
  BUF_CMD_FREEBLKS stategy op to the underlying device,
  which is executed unconditionally.  This basically runs
  an unconditional TRIM whether the 'trim' mount flag is
  specified or not.

  Remove the VOP_FREEBLKS() call.

* For softupdates operation, ffs_blkfree() handles the
  'trim' mount flag by issuing a BUF_CMD_FREEBLKS and
  sequencing the call to ffs_blkfree_cg() when it completes.

  When 'trim' was enabled, *two* TRIM operations were being
  executed on the underlying device, and prior to our fix,
  if 'trim' was not enabled, *one* TRIM operation would
  still be executed instead of zero.

* In many situations... possibly even most situations,
  trim operations seriously reduce performance due to
  being serialized by AHCI or by the target device.  It
  is not as useful as people often think it should be
  on normal filesystems.

* The removal of the unconditional TRIM significantly improves
  UFS performance, meaning primarily installkernel's
  since DragonFly doesn't use UFS for its main filesystem by
  default any more.

* The 'trim' mount option for UFS will still work as advertised
  when coupled with softupdates.
