- 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
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
* Use a common set of exception handlers for all arm32 platforms.
* New FIQ framework based on discussions with Ben Harris, shared
between arm26 and arm32.
The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.
Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.
This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.
RiscPC/A7000 have been tested and confirmed to build as should NC.
