18 years agoCorrect the API for Windows interupt handling a little. The prototype
wpaul [Sun, 20 Nov 2005 01:29:29 +0000 (01:29 +0000)]
Correct the API for Windows interupt handling a little. The prototype
for a Windows ISR is 'BOOLEAN isrfunc(KINTERRUPT *, void *)' meaning
the ISR get a pointer to the interrupt object and a context pointer,
and returns TRUE if the ISR determines the interrupt was really generated
by the associated device, or FALSE if not.

I had mistakenly used 'void isrfunc(void *)' instead. It happens the
only thing this affects is the internal ndis_intr() ISR in subr_ndis.c,
but it should be fixed just in case we ever need to register a real
Windows ISR vi IoConnectInterrupt().

For NDIS miniports that provide a MiniportISR() method, the 'is_our_intr'
value returned by the method serves as the return value from ndis_isr(),
and 'call_isr' is used to decide whether or not to schedule the interrupt
handler via DPC. For drivers that only supply MiniportEnableInterrupt()
and MiniportDisableInterrupt() methods, call_isr is always TRUE and
is_our_intr is always FALSE.

In the end, there should be no functional changes, except that now
ntoskrnl_intr() can terminate early once it finds the ISR that wants
to service the interrupt.

marcel [Sat, 19 Nov 2005 21:51:45 +0000 (21:51 +0000)]
Fix bug introduced in revision 1.186:
  When all file systems have a time stamp of zero, which is the case
for example when the root file system is on a read-only medium, we
ended up not calling inittodr() at all.  A potential uncleanliness
existed as well. If multiple file systems had a non-zero time stamp,
we would call inittodr() multiple times. While this should not be
harmful, it's definitely not ideal.
Fix both issues by iterating over the mounted file systems to find
the largest time stamp and call inittodr() exactly once with that
time stamp. This could of course be a zero time stamp if none of the
mounted file systems have a non-zero time stamp. In that case the
annoying errors mentioned in the commit log for revision 1.186 still
haven't been avoided. The bottom line is that inittodr() should not
complain when it gets a time base of zero. At the time of this
commit only alpha seems to have that problem.

jdp [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.

Rearranged the the optimizations for special cases to reduce the average

Use a non-bogus magic constant for the threshold of pi/4.  It was 2 ulps
smaller than pi/4 rounded down, but its value is not critical so it should
be the result of natural rounding.  Use "<=" comparisons with rounded-
down thresholds for all small multiples of pi/4.

Cleaned up previous commit:
- use static const variables instead of expressions for multiples of pi/2
  to ensure that they are evaluated at compile time.  gcc currently
  evaluates them at compile time but C99 compilers are not required
  to do so.  We want compile time evaluation for optimization and don't
  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
  the same way as the corresponding infinite precision expressions for
  multiples of pi/2, and 3*M_PI_2 happens to be rounded like this, so we
  don't need magic constants for the multiples.
