- Replace ipintrq and ip6intrq with the pktqueue mechanism.
- Eliminate kernel-lock from ipintr() and ip6intr().
- Some preparation work to push softnet_lock out of ipintr().
Discussed on tech-net.
The cnattach functions for sti(4) and service switch check method
for 425e in com_frodo.c are taken from OpenBSD.
The strategy how to choose the console device in hp300_cninit() is
quite diverged from 4.4BSD and OpenBSD so it's tweaked by me.
Also put several changes in sti_sgc.c to reduce diffs from OpenBSD/hp300.
Tested on 425e and 362 (which still uses gendiofb(4), not sti(4)).
XXX: sti(4) requires uvm_km_alloc(9) and uvm_map_protect(9)
to copy and call ROM functions on the executable memory region, so
it can be called before UVM and related initializations are complete.
Probably it's time to consider about MI "deferred consinit()" API
in init_main.c (or elsewhere) for modern complicated VM system...
- if commands timeout, clear the queues to the the card and perform a soft
reset on the LSI hardware since when these timeouts occur, the LSI firmware
is not graceful about recovering at all.
- Recover gracefully from more kinds of errors using the same recovery
mechanism listed above.
Also, implement mpt_ioctl() to handle bus reset requests from scsictl(8).
The four modules are apple_smc for the core functions, apple_smc_acpi
for attachment at acpi, and apple_smc_fan & apple_smc_temp for stuff
on the SMC.
Seems like there's a lot more bookkeeping necessary to maintain
children of an applesmc device implemented by loadable modules.
Maybe there's a better way I just haven't figured out yet.
Device interface derived by reading the Linux driver source code and
<http:///www.parhelia.ch/blog/statics/k3_keys.html> as of 2012-12-05.
Includes support for attaching fan and temperature sensors to sysmon.
No accelerometer yet.
Compile-tested only, based on some run-testing of experiments from
userland. Module attachment is not quite finished, so it won't work
yet.
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
- Add support for capturing initial CAP/CAP2/PI regs before reset (and
restoring them afterwords)
- Add optional callbacks for channel_start / channel_stop.
