868453d3d8 zephyr/modusocket: sock_read: Check socket status only at the start of packet. 
Otherwise, if we already have a packet in progress, finish it first, before
check "peer closed" status.

083cd21a74 zephyr: Add 96b_carbon configuration. 
As there's no networking support in mainline yet, networking is disabled,
because otherwise the board hangs on startup.

209eaec599 socket_send: Don't send more than MTU allows. 
As Zephyr currently doesn't handle MTU itself (ZEP-1998), limit amount
of data we send on our side.

Also, if we get unsuccessful result from net_nbuf_append(), calculate
how much data it has added still. This works around ZEP-1984.

84e17063c3 zephyr/modusocket: Strip packet header right in the receive callback. 
Instead of complicating recv() implementation.

96166ec165 zephyr/modusocket: socket_bind: Don't set recv callback on STREAM sockets. 
For stream sockets, next exected operation is listen().

1da8404647 modusocket: Handle a case when recv_q is empty when EOF is signaled. 
In this case, we can mark socket as closed directly.

faf333c04f zephyr/modusocket: Factor out "extended k_fifo API". 
Internal structure of k_fifo changed between 1.7 and 1.8, so we need
to abstract it away. This adds more functions than currently used, for
future work.

a9e6f08adb zephyr/Makefile: Add "test" target, runs testsuite in QEMU. 2017-04-05 00:46:00 +03:00

58168c8e6b zephyr/zephyr_getchar: Explicitly yield to other threads on char availability. 
Without this, if there's a large chunk of data coming from hardware (e.g.
clipboard paste, or fed programmatically from the other side of the console),
there's a behavior of initial mass fill-in of the buffer without any
consumption, which starts much later and doesn't catch up with further
filling, leading to buffer overflow.

2908c3ca41 zephyr/modusocket: Factor out socket_new() function. 
It will be reused e.g. for accept() implementation.

ca81c3ab0b zephyr/modusocket: Implement recv() for TCP sockets. 
Short read approach is taken - at most, the remaining data in the current
fragment will be returned.

3df65e9bae zephyr/modusocket: Implement recv() for UDP sockets. 
The foundation of recv() support is per-socket queue of incoming packets,
implemented using Zephyr FIFO object. This patch implements just recv()
for UDP, because TCP recv() requires much more fine-grained control of
network fragments and handling other issues, like EOF condition, etc.

4c307bfba1 all: Move BYTES_PER_WORD definition from ports to py/mpconfig.h 
It can still be overwritten by a port in mpconfigport.h but for almost
all cases one can use the provided default.

d1015f0e0d zephyr/modusocket: Initial version of usocket module for Zephyr. 
So far, socket creation and closure is implemented.

344bfbb71c zephyr: Fix NLR segfault in minimal build. 
Requires inclusion of zephyr.h to properly detect that we're building for
Zephyr.

df48f4645d zephyr/Makefile: Add workaround (fix?) for broken builds for DTS targets. 2017-03-30 15:16:55 +03:00

29dd92c82a zephyr/Makefile: Rework to use modern, official build integration. 
Build happens in 3 stages:

1. Zephyr config header and make vars are generated from prj.conf.
2. libmicropython is built using them.
3. Zephyr is built and final link happens.

dbb2aea428 zephyr/prj_base.conf: Disable legacy kernel compatibility. 
This keeps dependency on mdef, sysgen and other stuff which complicates
build integration.

40e541063f zephyr: Move "minimal" configuration building to a separate wrapper script. 
Minimal config can be now build with:

./make-minimal BOARD=...

This is required because of Makefile.exports magic, which in its turn depends
on PROJ_CONF to be set correctly at the beginning of Makefile parsing at all
times. Instead of adding more and more workarounds for that, it's better to
just move minimal support to a separate wrapper.

Also, remove Zephyr 1.5 era cruft from Makefile, and add support for Zephyr's
"run" target which supercedes older "qemu" target in upstream.

736a8a8ac7 zephyr: Make sure that generated prj.conf is updated only on content changes. 
This is a typical problem with make: we want to trigger rebuilds only
if file actually changed, not if its timestamp changed. In this case,
it's aggravated by the fact that prj.conf depends on the value of
BOARD variable, so we need to do some tricks anyway. We still don't
try to detect if just BOARD changed, just try to generate new
prj.conf.tmp every time (quick), but do actual replacement of prj.conf
only if its content changed.

a64a0276b3 zephyr/modzephyr: Add a module for Zephyr-specific things. 
Mostly intended to ease experimentation, no particular plans for APIs
so far (far less their stability), is_preempt_thread() provided is
mostly an example.

limitations/issues for a board they use.
