* refactor RPCSessionContext utils
* Make TVMLogf platform-independent.
* Some platforms need to use an alternate printf() to support basic
things like %zu. Since %zu is platform-specific, we prefer to
use a printf() that supports it or allow the platform to fix it up
as needed.
* Allow blocking read and write in micro transport, for debugging.
* add support for None timeout to micro transport, add tests
* fix GdbTransport and friends.
* GDB itself was just busted (would not launch inferior properly)
* GdbDebugger would kill the debugger without waiting for user
input. change to always wait for an explicit user quit.
* immediately resurrect Ctrl+C handler when debugger dies.
* remove on-terminate callback complexity, unnecessary
* [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
* address leandron@ comment from #6703
* Split transport classes into transport package.
* Introduce transport timeouts.
* black format
* Add metadata-only artifacts
* Simplify utvm rpc server API and ease handling of short packets.
* add zephyr test against qemu
* Add qemu build config
* fix typo
* cleanup zephyr main
* fix nonblocking piping on some linux kernels
* don't double-open transport
* validate FD are in non-blocking mode
* gitignore test debug files
* cleanup zephyr compiler
* re-comment serial until added
* remove logging
* add zephyr exclusions to check_file_type
* add asf header
* lint
* black format
* more pylint
* kill utvm rpc_server bindings, which don't work anymore and fail pylint
* fix compiler warning
* fixes related to pylint
* clang-format again
* more black format
* add qemu regression
* Fix paths for qemu/ dir
* fix typo
* fix SETFL logic
* export SessionTerminatedError and update except after moving
* fix test_micro_artifact
* retrigger staging CI
* fix jenkins syntax hopefully
* one last syntax error
* Add ci_qemu to Jenkinsfile
* build in qemu
* address liangfu comments
