* [BUGFIX] Respect infinite-timed session start timeouts.
* When debugging, the intended behavior is to set the session start
timeout to infinite to allow the user to configure the debugger.
* At present, if a session start retry timeout is defined, the
current logic will bail after the retry timeout expires.
* This change makes the session start logic retry forever, once per
retry timeout.
* Document RPCEndpoint::Create.
* Add stm32f746xx to tvm.target.micro() call; fix parameter name.
* This API is expected to just be used with positional args, not
kwargs, so this change isn't expected to cause any breakage.
* model is more inline with the rest of the file, given TVM Target
Specification RFC.
* [BUGFIX] If session start fails, exit transport context manager.
* If an error occurred during session setup, then complex transports
e.g. DebugWrapperTransport would not de-initialize.
* Align transport writes/reads in TransportLogger
* fix syntax errors which were not exercised in previous PR
* Remove microTVM logic from standard RPC server, add debug shell.
* microTVM uses the host RPC server as a way to launch a debugger in
a dedicated, separate terminal window. microTVM needs to be able to
launch the debugger itself, because its model of the device
flash/debug flow separates these two things into distinct
operations implemented by shell commands (for maximum portability
across frameworks).
* microTVM can be configured to launch the debugger (e.g. GDB) in the
same terminal as is used for flashing, but this is sub-optimal
because then it hides any logs emitted by the device.
* Using the standard RPC server was hard because GDB expects the user
to issue SIGINT to interrupt program flow, but due to the RPC
server's necessary use of multiprocessing, multiple signal handlers
needed to be SIG_IGN'd, and further, because libtvm.so is
intentionally frontend-agnostic, it's difficult to include signal
handling directly in that binary (Python expects you to call
PyErr_CheckSignals, but we don't require and don't want to require
python-dev to compile libtvm.so, and this is the only such case
where libtvm.so is expected to block the main thread for a long
period of time).
* Here we implement a separate microTVM debug shell python script
using the non-blocking server implementation.
* Add serial transport, parameterize test_zephyr to work on real hardware
* add pytest test fixture, missed from previous change.
* this test fixture helps to parameterize the test case
