Port Reset R/W. 1=Port is in Reset. 0=Port is not in Reset. Default = 0. When
software writes a one to this bit (from a zero), the bus reset sequence as defined in the
USB Specification Revision 2.0 is started. Software writes a zero to this bit to terminate
the bus reset sequence. Software must keep this bit at a one long enough to ensure the
reset sequence, as specified in the USB Specification Revision 2.0, completes. Note:
when software writes this bit to a one, it must also write a zero to the Port Enable bit.
Note that when software writes a zero to this bit there may be a delay before the bit
status changes to a zero. The bit status will not read as a zero until after the reset
has completed.

Fix SEARCH command in imap4d by replacing the cistrstr typo with cistrcmp.

openmode() can raise error with invalid mode passed, but we already
incremented the exclusive mouse refcount at that point! call openmode()
early to avoid this.
|
|
only decrement refcount when file was successfully opend
on clunk, fix refcount when devopen() errors.

spawn a kernel process to check the broken state of the controller.
if the firmware crashed, or rfkill was toggled we will reset and
reboot the firmware. also power down the card when rfkill is off.

double the td abort delay and make sure the tsleep() isnt
shortened by a pending note. in that case, tsleep() would
raise error(Eintr); immidiately and would not sleep the
requested amount potentially cauing us to release active
dma memory too early! so we wrap the tsleep() call in a
while(waserror()) so we will at least wait the Abortdelay
amount if error is raised.
also, only try to idle the still active td's.
do not copy data in epio() when there was an error, theres
no reason to touch user buffer in that case.
for uhci, we also check that theres not more data in the
buffers than requested to avoid overflowing user buffer
in epio(). this should not happen but we'r paranoid.
for ehci, we also halt the queue head first in aborttds().
mark the queue heads as Qfree after unlinking and remove
some silly nil checks that are impossible.

on races... normal forks will all share the /env environment but
not the in memory variables of rc. so when we would normally fork
whoever does an exec (flush) first will override what the values of the
/env variables are, *independent* of the variables that where
actually modified *in* the process.
when we flush *before* fork, then at least both processes start out
with marked clean in memory variables and the processes will flush
only the things they actually change.

the resizing fails if run with rio in rio. dont try
to be too clever.
|
|
the "auth" ctl command only sets the rsne of the current selected
access point. so on deassociation, we wait for the connection to
the potentially new access point and then setup new rsne before
processing eapol messages.

when receiving interrupt note
fix the default note handler for event programs. only handle non system
notes or notes in the slave processes. for interrupt in the main process,
just call exits() which will do the cleanup and restore window label
properly.
this makes completely overriding the note handler in gping and
stats uneccesary.

this program allows one to stream audio from linux/windows
to plan9 /dev/audio. sometimes handy to augment vnc sessions
with sound.

screens 0-3 are already initialized by V_Init().
|
|
many queued mouse events delay eresize() because
new ebread() takes from the queue first before attempting
to read from the event pipe. this is a waste of memory, so
just process (dequeue) all the events as long as there are
any on each iteration.

timestamps)
from the manual:
Tm2sec converts a broken-down time to seconds since the
start of the epoch. It ignores wday, and assumes the local
time zone if zone is not GMT.
so we can assume localtime if Tm.zone is not set to GMT.
all code that wants no localtime conversion should set
Tm.zone explicitely to GMT. (see previous commits)
tm2sec() now does the reverse of localtime() when Tm.zone[0] == 0
which seems to be what the calling code (dossrv, zipfs) assumes.
this also makes sense because theres no simple way todo it
outside of libc as theres otherwise no access to the timezone
structure with the daylight saving periods.
|
|
tm2sec() ignores tm.tzoff and will use the local timezone for
conversion. to make it work right, we convert the dos timestamp
as GMT and then correct timezone with the offset provided by the
server.

"miscellaneous"
instructions like BKPT, BX and BLX. Decoding these correctly allows db/acid to
single step through BX and BLX on armv5t+, and to show a breakpoint instruction
as 'BKPT $#0' instead of 'TEQ R0@>R0,R0'.
