Patrick Porlan 2f0485e757 ringbuffer: Switch ringbuffer to g_slice allocator 
This should allow for more efficient handling of equally sized
buffers, in terms of alignment and recycling.

Patrick Porlan bb0e3e0a58 PPP: Optimize write buffer management 
Extend the write buffer handling in gathdlc.c to minimize stalling and
process switching during large PPP transfers. The single write buffer
is replaced by a queue of buffers, allowing for much larger emission
windows without hugely impacting memory consumption. This reduces the
time required to send 50 MB between a couple of local PPP interfaces on
my laptop from ~53s to ~3s.

Patrick Porlan 992019cad4 gatchat: Optimize ringbuffer modulo operations 
Replace modulo operations in ringbuffer.c by masking operations.  This
is possible because the size of the ring buffers is always a power of
two, and yields a small performance improvement.

The improvement should be mostly visible on processors that implement
division in microcode (Atom) or lack a division instruction (ARM).

Denis Kenzior ef49d65b70 gsmdial: Introduce data_mode 
If we're in PPP mode, then don't send unsolicited notifications.  Only a
NO CARRIER is really allowed.

Denis Kenzior 51d950994d gatserver: Tweak use of g_at_server_suspend/resume 2011-02-28 16:13:56 -06:00
Denis Kenzior d3350d6662 test-server: Make sure to send CONNECT 
Before starting the ppp session we should make sure that the CONNECT
response has been sent on the wire.

Denis Kenzior 4da1a9318c gatserver: Exit garbage state on HDLC frame end 2011-02-28 16:13:56 -06:00
Denis Kenzior 6f8675d7fa gatppp: Try to detect no carrier conditions 2011-02-28 16:13:56 -06:00
Denis Kenzior ea56a71067 gatppp: Delay signaling ppp_down 
Delay signaling of ppp_down until we exit the GAtHDLC read handler.
Otherwise exchanging the read handler on GAtIO might lead to funny
double consumption problems.
 2011-02-28 16:13:56 -06:00
Denis Kenzior 0dc8e5e588 gathdlc: Try to detect no carrier conditions 
Sometimes we receive the no carrier embedded in a stream following the
PPP packets.  This might be due to write scheduling on the remote side
or read scheduling locally.  Try not to consume the no carrier condition
and assume the previous hdlc frames will result in closing of the ppp
stack.

Denis Kenzior 09ca5aaef0 gathdlc: Unregister read / write handlers 
When GAtHDLC is being unregistered make sure to unregister read / write
handlers so as not to crash.
 2011-02-28 16:13:56 -06:00
Denis Kenzior 1cbe91090d gathdlc: drain the last hdlc frame processed 
If we're being destroyed, we should drain the last HDLC frame

Denis Kenzior b6bc221bc8 gatppp: Send the final terminate ack 
In the case where we're going down, but have a pending terminate ack,
delay signaling the upper layers until the ack has been put on the wire.

Denis Kenzior 5ffe6f7beb gatio: Add write 'done' notifier 
This allows external clients to get notified when GAtIO no longer has a
registered write watcher.  E.g. no more data is currently pending.

Denis Kenzior 92404672fc gatserver: Update the internal command parsers 
commit 61b30c025d changed the way the
command callbacks are being called (namely the contents of the GAtResult
object).  Most command callbacks were updated, but the internal ones
were forgotten.  This patch fixes this issue.

Guillaume Zajac 205d40db82 test-server: Fix crash when remote disconnects 
If the remote side kills the connection when PPP is established, we
should not try to resume the AT server.

Martin Xu 694589f51d PPP: Use default ACCM (0xffffffff) to trasmit 
Using my Huawei EM770W modem, if set ACCM as 0x00000000, RXJ-
event breaks PPP link, after IP package transmit for a while.
Using default ACCM, the issue can be fixed.
I tested it at China Unicom networks.

Denis Kenzior 61b30c025d gatserver: Don't bother reporting command prefixes 
The command line parser knows where the actual command line parameters
begin, so there's no need to make the callback skip the prefix and the
additional separator characters.

As g_queue_peek_head() returns the node data field, we have to compare
it against the actual command, not against the pointer to the queue node.
