"void *", and do the extra de-reference directly in the function. this
avoids having to cast dozens of different types to "void **", which sets
of GCC3's strict-aliasing. testing by martin@
by sparc for PROM console input channel. Demote it to kd.c as a
static variable.
While there, use callout_schedule instead of callout_reset to
reschedule the PROM polling callout, and init prom_cons_channel
statically.
bus_space_{read,write}_[1248]() functions, which will allow 16-bit
PCMCIA support to work without additional hacks in MI drivers.
this option is not enabled yet.
To make this work, we now have to use separate handler lists for hardware
and software interrupts as the soft interrupt handlers do not return
an `interrupt handled' status.
Thanks to Matt Fredette for providing an initial set of patches on port-sparc.
raise the ipl in the interrupt handlers to the appropriate level. This avoids
interrupt handler interference if one of the devices actually interrupts at
a lower hardware level than the maximum level assined to a device class.
Based on code from Art Grabowski in openbsd.
- disk_unbusy() gets a new parameter to tell the IO direction.
- struct disk_sysctl gets 4 new members for read/write bytes/transfers.
when processing hw.diskstats, add the read&write bytes/transfers for
the old combined stats to attempt to keep backwards compatibility.
unfortunately, due to multiple bugs, this will cause new kernels and old
vmstat/iostat/systat programs to fail. however, the next time this is
change it will not fail again.
this is just the kernel portion.
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
