2017-09-07Rebase branch 'profiling' from masterPaul Selkirk
2017-09-07Add task_yield_maybePaul Selkirk
2017-09-07Sigh, right offset for the wrong register. Get the PC (the address wePaul Selkirk
interrupted) rather than LR (the return address from the function we interrupted). Also, change u_short and u_int to unsigned short and unsigned int, since gcc recently decided that those aren't part of the C99 standard. Finally, add profilable versions of memcpy, memset, and friends, because they get called a lot in the course of unit testing, and it would be nice to know who's calling them.
2017-09-07Port profiling code, using a new SysTick hook and new CLI commands.Paul Selkirk
2017-09-07Add some task metrics.Paul Selkirk
2017-08-31Withdraw SysTick_hook (commit 9ffead1), because it turns out there was ↵Paul Selkirk
already a user-callback mechanism with HAL_SYSTICK_IRQHandler() and HAL_SYSTICK_Callback().
2017-07-31Report UART receive queue length, so we can tune it.Paul Selkirk
2017-07-31Adapt uart_rx_thread to the post-thread tasking model, because we're stillPaul Selkirk
subject to the same forces that made it a good idea in the first place. commit 2b6b9f8 Change RPC UART to have a high-priority thread monitoring a large(ish) DMA buffer, because we've observed out-of-order receives under load.

2017-05-02Merge branch 'init_cleanup' into no-rtosPaul Selkirk
Clean up Makefiles and initialization code.
2017-04-30Merge branch 'ksng' into no-rtosRob Austein
Required minor manual intervention to resolve merge issues git had no way of understanding: git is clever, but not quite clever enough to understand that a commit in branch had removed the entire RTOS that a commit in the other branch was using. No big deal, just a couple of osDelay() calls needing conversion to HAL_Delay() or task_delay().
2017-04-29Add minimal mutexes to the minimal tasking systemPaul Selkirk
2017-04-29Simplify hsm makefile.Paul Selkirk
2017-04-27Replace the RTOS with a simple cooperative tasker.Paul Selkirk
There are no priorities and no preemption, so tasks run in a round-robin fashion, and explicitly yield control.
2017-04-27Refactor cryptech_upload to work either directly or via cryptech_muxd.Rob Austein
2017-04-26Add support for hal_sleep().Rob Austein
2017-04-17Add a short delay to osMailAlloc, since we're no longer calling it in an ISR.Paul Selkirk
2017-04-17Merge remote-tracking branch 'origin/uart_rx_thread' into ksngPaul Selkirk
2017-04-16Switch to libhal's CRC-32 code.Rob Austein
2017-04-15Missing include files, doh.Rob Austein
2017-04-15sw/stm32 Makefiles are a mess.Rob Austein
Apparently it's easier to duplicate source files into multiple project directories than to write Makefiles that do something sane. Feh.
2017-04-15Move hal_log() support to separate module.Rob Austein
2017-04-15Logging implementation for Alpha hardware.Rob Austein
2017-04-12Handle race condition while fetching key metadata for display.Rob Austein
Fetching a list of keys and all of their metadata isn't an atomic process, nor, probably, should it be, so we need to cope with things like a key being deleted via the RPC interface while we're fetching its metadata for display on the console interface.

buffer, because we've observed out-of-order receives under load.
2017-03-02Try to be a bit more robust in the face of normal errors.Paul Selkirk
If hal_rpc_server_dispatch() returns an XDR decode error because the request packet was too short, don't call Error_Handler() and kill the dispatch thread, just drop the request. Add more ibuf_queue entries, but don't panic and kill the dispatch thread if we can't get one, just drop the incoming character (which will lead to an XDR decode error if/when we finally get an ibuf).
2017-02-23Add --pin and --quiet options.Paul Selkirk
2017-02-23Speed up file upload enormously.Paul Selkirk
We need to start with a long serial timeout, in order to catch the reboot messages for a firmware upload (this has to be done through the bootloader). But once we start sending the file, cut the serial timeout to 1ms. (I've tested it down to 1us, but that may not work for everyone, and it doesn't improve performance in a statistically significant way.) This brings the time to upload a 4.5MB bitstream from 38:23 to 1:25.
2017-02-22Refactor flash code.Paul Selkirk
2017-02-21Use libcli return codes where appropriate; show whether PINs are set.Paul Selkirk
2017-02-21Use bulk erase in the one place it makes sense.Paul Selkirk
2017-02-02Add locking around keystore operations.Rob Austein
2016-12-23Don't wrap key number in "keystore show keys".Rob Austein
2016-12-21Rewrite core upload loop to simplify and fix race conditions.Rob Austein
The main loop in cryptech_upload:send_file() was much more complicated than necessary, and also contained some hidden assumptions about serial I/O timing which happened to fail on the first two machines I tested. We already had a perfectly good buffered-input function, so rewrote to use that, and simplified control structure in the process. In theory, the new code should work in any environment where the old one did, but this has not yet been confirmed.

2016-12-20Merge branch 'master' into ksngRob Austein
Bootloader DFU fixes.
2016-12-20The bootloader upgrade reboots now, so we don't need to log out of the CLI.Paul Selkirk
2016-12-20Fix bootloader upload callback routine to write the correct number of bytes ↵Paul Selkirk
to flash. While we're at it, propagate error returns.
2016-12-20cli_receive_data: re-enable UART DMA before returning. Based on Fredrik's ↵Paul Selkirk
fix to cli-test, commit ae8ebce.
