hi,
i just fixed some
locking issues the last days. fix will follow. it took a bit longer,
because there were some race conditions. it took up to about one hour until
it crashed. my way to detect the area where the crash happened, was to turn on
buzzer before that area, and turn it off after that area. after many hours of
approximation, i finally found out that the major crash happend during
_talloc_zero. (first it looks for a free memory chunk, then it allocates
it.) since it can be called from all contexts (main, irq, fiq), it need to be
locked against any interrupt, otherwise the memory chunk can be assigned
multiple times. (the process of _talloc_free is "atomic" and requires no
locking.)
because it seems
pretty stable, i think it is time to merge some branches into the master.
(i made a 6 hours call yesterday. and no crash after bugfix ever since.) i
will do that together with sylvain, if we find the time this
weekend.
currently i use the
jolly/voice together with the sylvain/traffic branch. i am able to use
an isdn phone togehter with linux-call-router and make/receive calls. audio
is passed both ways. i think this is a stage where it actually become
"usable". (if not moving arround.)
one of my
major work for the next weeks/months will be the neighbour cell
measurement, cell re-selection, and handover. this is essential when moving with
the phone.
regards,
andreas
