different cards that matched vendor/id, but weren't wi cards. This is
because the vendor foolishly didn't have unique product ids. Symbol
has a serial card that would otherwise match the wi driver, for
example...
Taken from a patch for xe posted by: Carlos Velasco
which doesn't support ACPI power states. Return AE_NOT_FOUND for these
cases and don't print the warning message. Also, print the name of the
handle instead of device when unable to switch states. The device is often
not attached at this point and so its name is NULL, which doesn't help
debugging.
"stray irq 9" messages on my Thinkpad. It may also help with general
reboot consistency although the recent hang on reboot was solved by
acpi_cpu.c rev 1.39.
after. Unify the paths for all Cx states. Remove cpu_idle_busy and
instead do the little profiling we need before re-enabling interrupts.
Use 1 quantum as estimate for C1 sleep duration since the timer interrupt
is the main reason we wake.
While here, change the cx_history sysctl to cx_usage and report statistics
for which idle states were used in terms of percent. This seems more
intuitive than counters. Remove the cx_stats structure since it's no
longer used. Update the man page.
Change various types which do not need explicit size.
called ttyldoptim().
Use this function from all the relevant drivers.
I belive no drivers finger linesw[] directly anymore, paving the way for
locking and refcounting.
exactly as done in the cmi driver. I am quite confident this is
safe since I'm runing this for more than two weeks now, on an SMP
box. A few people tested this patch for me successfully as well.
- In subr_ndis.c, my_strcasecmp() actually behaved like my_strncasecmp():
we really need it to behave like the former, not the latter. (It was
falsely matching "RadioEnable", which defaults to 1 with "RadioEnableHW"
which the driver creates itself and to 0, because we were using
strlen("RadioEnable") as the length to test. This caused the radio to
always be turned off. :( )
- In if_ndis.c, only set IEEE80211_CHAN_A for channels if we actually
set any IEEE80211_MODE_11A rates. (ieee80211_attach() will "helpfully"
add IEEE80211_MODE_11A to ic_modecaps for you if you initialize any
802.11a channels. This caused "ndis0: 11a rates:" to erroneously be
displayed during driver load.)
- Also in if_ndis.c, when using TESTSETRATE() to add in any missing 802.11b
rates, remember to OR the rates with IEEE80211_RATE_BASIC, otherwise
comparing against existing basic rates won't match. (1, 2, 5.5 and
11Mbps are basic rates, according to the 802.11b spec.) This erroneously
cause 11Mbps to be added to the 11b rate list twice.
sysctls were global (hw.fxp_rnr and hw.fxp_noflow), all of them are
now per-device. Sample output of "sysctl dev.fxp0" with this patch,
with the standard %foo nodes removed :
dev.fxp0.int_delay: 1000
dev.fxp0.bundle_max: 6
dev.fxp0.rnr: 0
dev.fxp0.noflow: 0
protect the registers so it was trivially possible for a sync command and
i/o command to fight each other and confuse the controller. Make the
sync fib alloc/release functions inline and remove the somewhat worthless
AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track
this down in RELENG_4.
It was based on the pty(4) driver which as a tty side an a non-tty side.
Nmdm(4) seems to have inherited two symmetric sides from pty but
unfortunately they are not quite ttys. Running a getty one one
side and tip on the other failed to produce NL->CRNL mapping for
instance.
Rip out the basically bogus cdevsw->{read,write} functions and rely
on ttyread() and ttywrite() which does the same thing.
Use taskqueue_swi_giant to run a task for either side to do what
needs to be done. (Direct calling is not an option as it leads to
recursion.) Trigger the task from the t_oproc and t_stop methods.
Default the ports to not ECHO. Since we neither rate limiting nor
emulation, two ports echoing each other is a really bad idea, which
can only be properly mitigated by rate limiting, rate emulation or
intelligent detection. Rate emulation would be a neat feature.
Ditch the modem-line emulation, if needed for some app, it needs
to be thought much more about how it interacts with the open/close
logic.
