- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
standard scheme:
if (<configured> != <wildcard> && <configured> != <real>)

ask device match function
This is handled by config_stdsubmatch() now.

be toggled in WE_MEM_{ENABLE|DISABLE} when receiving or transmitting packets.
Use this to switch the toggle off for MCA cards, since it causes NIC resets
there.

which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Fix some non-initialized variables
close the output files when done
Redo the printing for RCS strings so they don't expand in the awk script too
Do proper tests for variables existance before accessing
Verified output from all scripts is identical to original versions
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
- 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.
- 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.
flag to clear, even when the COMMAND COMPLETE interrupt already did happen,
otherwise we get ATTENTION ERROR for next command if it happens soon
enough; this fixes the reliability problems introduced by previous change
some other cleanup & simlify of edc_cmd_wait()/edc_run_cmd(), the 'secs'
is just a hint used in !poll case only
add some comments
move status_block[] back to edc_mca_softc, to save stack memory
make #ifdef DEBUG #ifdef EDC_DEBUG and g/c some obsolete debug stuff
make some EAGAINs EIOs
edc_intr(): wakeup the waiter for any command, not just READ/WRITE DATA
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
for the i82596 PORT access interface, from the documentation
for that chip. These help clarify writes to the SYSBUS
part of the SCP, and PORT usage by i82596-aware drivers.
* simplify and clean the attach code a lot, and support the 'drive'
locator
* pass proper dev_t to readdisklabel() - formerly, the passed value was
completely broken (used incorrect major and wrong minor), but worked
by accident
* worker thread is now spawned per controller, rather than per-drive;
i/o cannot be done concurrently by different drivers, only one
i/o can be pending at any time
* simplify the command queue code, just sleep appropriately when
!poll case, g/c 'async' code formerly needed, move the bio code
from ed_mca.c to edc_mca.c:edc_bio()
* other misc cleanups
the MCA DMA controller access. This also means we gain >16MB RAM support.
While here, overhaul the driver to saner state, especially:

DIAGNOSTIC/DEBUG from the kernel. This helped to boost the performance
on my test machine from ~5KB/s to like 800KB/s for ftp test, and
to like 700KB/s for netio test. I wouldn't have imagined the options
are THAT costly ....
and for initial autoconf probes; the latter eliminates need for
deferred configuration (and makes dmesg a bit nicer).
g/c EDF_IODONE flag - protect against interrupt by calling tsleep()
at splbio in worker thread
g/c unneeded stuff, improve some autoconf messages
Both models tested and seem to be quite stable and fast.
Thanks to:
- Hans Hubner <hans@Huebner.org> for giving me the cards for testing
- Georg Klug of Syskonnect, who provided me with hw docs for these cards,
very promptly and willingly - I wish all vendors would be like this
- Alfred Arnold, Linux SKNET driver author, for giving me valuable Syskonnect
contact :)
