be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.
To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.
All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
- Add support for byte system bus mode. Based on patch in kern/17193 by
Christian Groessler, with some improvements by me.
- Rename sc_flags in mb86960_softc to sc_stat, rename "type" to sc_flags
to specify controller quirks and remove enum mb86960_type.
- Pass controller type via new sc_flags in mb86960_softc rather than
via an mb86960_attach() arg.
- Handle unaligned mbufs properly in mb86960_write_mbufs(). (from ne2000.c)
- Fix a signed/unsigned comparision warning.
- Add definitions of status bits in the RX packed header.
- Change types of some members in mb86960_softc.
- Move lm_readreg/lm_writereg into the front-ends. Add/use function pointers
in the softc.
- Add a bank select function pointer to the softc and provide a generic
version. WinBond chips accessed over serial bus present three addresses,
two of which are used to access bank 1/2 registers.
- Mark TSENS2/3 sensor data as invalid if the the corresponding bank select
fails.
XXX Now, could someone please explain to me why in the love of Bob a
file containing inline x86 assembler is in sys/dev/isa/????
This should be moved, fixed, or nuked from space.
- 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
