John Polstra [Fri, 18 Nov 2005 02:43:49 +0000 (02:43 +0000)]
Fix a bug that caused some /dev entries to continue to exist after
the underlying drive had been hot-unplugged from the system.  Here
is a specific example.  Filesystem code had opened /dev/da1s1e.
Subsequently, the drive was hot-unplugged.  This (correctly) caused
all of the associated /dev/da1* entries to be deleted.  When the
filesystem later realized that the drive was gone it closed the
device, reducing the write-access counts to 0 on the geom providers
for da1s1e, da1s1, and da1.  This caused geom to re-taste the
providers, resulting in the devices being created again.  When the
drive was hot-plugged back in, it resulted in duplicate /dev entries
for da1s1e, da1s1, and da1.

This fix adds a new disk_gone() function which is called by CAM when a
drive goes away.  It orphans all of the providers associated with the
drive, setting an error condition of ENXIO in each one.  In addition,
we prevent a re-taste on last close for writing if an error condition
has been set in the provider.

- use static const variables instead of expressions for multiples of pi/2

  care about side effects.
- use M_PI_2 instead of a magic constant for pi/2.  We need magic constants
  related to pi/2 elsewhere but not here since we just want pi/2 rounded
  to double and even prefer it to be rounded in the default rounding mode.
  We can depend on the cmpiler being C99ish enough to round M_PI_2 correctly
  just as much as we depended on it handling hex constants correctly.  This
  also fixes a harmless rounding error in the hex constant.
- keep using expressions n*<value for pi/2> in the initializers for the
  static const variables.  2*M_PI_2 and 4*M_PI_2 are obviously rounded in

From luigi:
In SNDCTL_DSP_SETFRAGMENT, if you specify both read and
write channels, the existing code first acts on the
read channel, but as a side effect it updates the
arguments (maxfrags, fragsz) passed by the caller according
to acceptable values for the read channel, and then uses the
modified values to act on the write channel.
The problem with this approach is that, given a
(maxfrags, fragsz) user-specified value, the actual
values computed by the read and write channels may differ:
e.g. the read channel might want to allocate more fragments
than what the user specified because it has no side-effects
on the delay and it helps in case of slow readers,
whereas the write channel needs to use as few fragments
as possible to keep the audio latency low (very important
with telephony apps).

This patch stores the values computed by the read channel
into temproary variables so the write channel will use
the actual arguments of the ioctl.

This patch is very helpful with telephony apps such as asterisk.

The code to compute fragment sizes in the ich driver almost

how the user specifies fragment size and number.
With audio telephony (8khz, 16bit-stereo) and the 16k buffer
size this results in an unbearable 500ms delay.
This patch makes sure that we never use more than 4 fragments,
(i don't think we need more unless there are huge interrupt
servicing latencies), and obey to the requested fragment size,
so that latency is acceptable.
  Based on this (and after much regression tests), I can conclude
