those files are not available in certain phases in the build process,
notably the "obj" phase, so unconditionally decend into siginfo during
that pass. This should make read-only source trees build again when
cross-compiling for a target supporting siginfo on a host not supporting
siginfo.
close sockets on address changes, which was deemed to be a bad idea and was
summarily removed, so there is no point in wasting effort on maintaining it
any more.
* don't set the NOCRC bit in the mode control register, it can cause
problems on some chips (from the broadcom errata via FreeBSD)
* implement a fallback quirktable that is searched only using the
major asic revision, so that the driver has a shot at supporting
newer versions properly without modification
* rename asicrev -> chipid, like the FreeBSD driver
instead.
With this change, we no longer need to save the current interrupt level
in the switchframe. This is no great loss since both cpu_switch and
cpu_switchto are always called at splsched, so the process' spl is
effectively saved somewhere in the callstack.
This fixes an evbarm problem reported by Allen Briggs:
lwp gets into sa_switch -> mi_switch with newl != NULL
when it's the last element on the runqueue, so it
hits the second bit of:
if (newl == NULL) {
retval = cpu_switch(l, NULL);
} else {
remrunqueue(newl);
cpu_switchto(l, newl);
retval = 0;
}
mi_switch calls remrunqueue() and cpu_switchto()
cpu_switchto unlocks the sched lock
cpu_switchto drops CPU priority
softclock is received
schedcpu is called from softclock
schedcpu hits the first if () {} block here:
if (l->l_priority >= PUSER) {
if (l->l_stat == LSRUN &&
(l->l_flag & L_INMEM) &&
(l->l_priority / PPQ) != (l->l_usrpri / PPQ)) {
remrunqueue(l);
l->l_priority = l->l_usrpri;
setrunqueue(l);
} else
l->l_priority = l->l_usrpri;
}
Since mi_switch has already run remrunqueue, the LWP has been
removed, but it's not been put back on any queue, so the
remrunqueue panics.
a different BSS, because that keeps drivers like atw from detecting
ad hoc beacons with the same SSID but different BSSID for the
purpose of IBSS merges.
This should be revisited: maybe drivers should check for beacons
before handing packets up with ieee80211_input(). However, this
restores the atw(4) to working like it did with the old 802.11
layer, and it *is* nice to re-use the 802.11 layer's packet-decode
& -dispatch code (i.e., the ic_recv_mgmt callback).
According to the ICH datasheets, the flag is unchanged unless resetting
the codec.
The flag is useless after enabling bus mastering. This behavior is common
to all ICH chips. The quirk handling code is removed.
a copy of the interrupt cookie which isn't used outside the attach. We
has also bogusly only told the autoconfiguration machinery that our softc
was as big as a ohci_softc_t, not a struct aubus_ohci_softc.
Also, disestablish the interrupt if OHCI initialisation fails.
This driver ignores i/o window handle, but most 'at pcmcia'
attachments init their sc_io_window to -1 and then check at detach
time if it was changed from the "bad" value. Keep them happy, so that
they can correctly clean up when card is detached.
