sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40+00:00

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Separate the hardware definitions into ipsreg.h so they can be used by

2005-11-29T09:39:41+00:00

future userland tools.

Fix build.

Report status in hex, not decimal.

Overhaul error handling in the IPS driver. Don't use a magic value for

2005-09-25T17:12:41+00:00

driver-induced errors, instead be better about propagating error status
upwards.  Add more error definitions, courtesy of the linux driver.  Fix
a command leak in the ioctl handler.  Re-arrange some of the command handlers
to localize error handling.

Lock the IPS driver and bring it out from under Giant. Also do some

2005-01-28T05:02:13+00:00

significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
  us.
- remove all of the complicated bio deferral code.  bio's that can't be
  serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
  This simplifies a lot of code and significantly reduces the size of the
  command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
  call it indirectly.

MFC After: 1 week

Change the return value of sema_timedwait() so it returns 0 on

2004-06-14T18:19:05+00:00

success and a proper errno value on failure.  This makes it
consistent with cv_timedwait(), and paves the way for the
introduction of functions such as sema_timedwait_sig() which can
fail in multiple ways.

Bump __FreeBSD_version and add a note to UPDATING.

Use a unique malloc type rather than M_DEVBUF.

2004-05-30T04:01:29+00:00

Switch from using mutexes to using semaphores to protect against early

2004-02-28T19:14:41+00:00

completion of synchronous commands.  Also switch to a per-array bioq as it
appears to improve performance.

The reset_type should not be 0x80, it should be set to zero.

2004-01-01T10:22:10+00:00

0x80 can cause the command to be rejected as invalid. This bug
exists also in the Linux IPS ffdc code.
