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.
size_t and size_t *, respectively. Update callers for the new interface.
This is a better fix for overflows that occurred when dumping segments
larger than 2GB to core files.
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.
<sys/linedisc.h> (repocopied).
Temporarily use a nested include from <sys/tty.h> to get <sys/linedisc.h>
into relevant source files.
Introduce a set of inline functions named ttyld_...() to invoke
linedisc methods instead of groping around in the linesw array.
class variables in addition to per-device variables. In plain English,
this means that dev.foo0.bar is now called dev.foo.0.bar, and it is
possible to to have dev.foo.bar 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.
double NULL entries signal Witness to stop processing the array of
order entries meaning none of the spin locks are added resulting in
panics on boot.
- Add a missing NULL, NULL terminator to the Slip locks list to keep them
separate from the spin locks.
that m_prepend() is not called with possibility to wait while the
pcb lock is held. What still needs revisiting is whether the
ripcbinfo lock is really required here.

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
