2021-09-13Initialize I/O pins of SPI3, which is used to configure iCE40-based MKM.Pavel V. Shatov (Meister)
Note, that SPI3 is alternate function 6, unlike SPI1 & SPI2 which are both AF5.
2020-10-15Reduce overly-long HAL_IO_TIMEOUT.Paul Selkirk
2020-07-13Whack all Python shebangs to Python 3Rob Austein
2020-05-05Add more RPC tasks for better signing performance.Paul Selkirk
2020-03-09Replace the brutally inefficient fp_to_unsigned_bin with one based onPaul Selkirk
fp_read_unsigned_bin. I thought about patching it directly in sw/thirdparty/libtfm, but ultimately decided to keep that pristine (especially since we verify file checksums there).

2018-12-05Tell libtfm that the ARM is little-endian, so it can optimize ↵Paul Selkirk
fp_read_unsigned_bin(). This enables some overflow-detection code, which fixes CT-01-009. It also saves 484us/call, which adds up to 6.3ms/RSA signature.
2018-12-03Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in.Paul Selkirk
2018-12-02Clean up the profiling code to the point where I stand a chance ofPaul Selkirk
understanding it 6 months from now. While I'm at it, try to make it a little more efficient (because 50-60% of time in a typical profiling run is spent in the function-entry counting), and collapse profil.c into gmon.c.
2018-11-26Add loop unrolling to bring the profilable mem* functions closer toPaul Selkirk
newlib, because memset is called a LOT in the course of RSA signing, and we need to understand how much time we're actually spending there.
2018-09-04Make parsing and display of masterkey values consistent with one another,Paul Selkirk
so the user might be able to copy and paste a generated key into the CLI for recovery. Display had been a 32-byte hexdump. Parsing (manual re-entry of the KEK) had been 8 32-bit little-endian values. This has been a pain point for literally two years, albeit at a low enough pain level that I've managed to cringe and ignore it.
2018-05-27Script to run a test with HSM profiling.Rob Austein
2018-05-01Fix mbed vpath not to use explicit (and wrong) pathsPaul Selkirk
2018-04-19Cleanup: warn of signed/unsigned mismatches in libhal.Paul Selkirk
This is from October's cleanup binge, but I forgot to commit it at the time.

2017-10-11Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.Paul Selkirk

2017-09-07Rebase branch 'profiling' from masterPaul 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.
2017-09-07Correct offset to get the PC.Paul Selkirk
A previous version of this code ran over the RTOS, where threads used the Process Stack, while the SysTick interrupt used the Main Stack. Now everything's on the main stack, so we need to account for 2 extra words that SysTick_Handler pushes on the stack at entry.
2017-09-07Port profiling code, using a new SysTick hook and new CLI commands.Paul Selkirk
2017-09-07Copy profiling code from MCUOnEclipse.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().
2017-07-31Add a generic SysTick hook, to call a function on every 1ms tick, because ↵Paul Selkirk
it's easier than setting up a dedicated timer.

2017-04-29Remove exception handlders that I probably shouldn't have defined in the ↵Paul Selkirk
first place.
2017-04-29Remove rtos source files.Paul Selkirk
2017-04-17Use default SysTick interrupt priority.Paul Selkirk
We really don't want SysTick_Handler, which runs the task scheduler, to run at a higher priority than SVC_Handler, which runs supposedly-atomic operations like mutex locking and unlocking. I've seen a mutex lock/unlock mismatch which I think is due to interrupting rt_mut_release at a particularly inopportune moment.
2017-04-01Change RPC UART to have a high-priority thread monitoring a large(ish) DMAPaul Selkirk
buffer, because we've observed out-of-order receives under load.
2016-09-20Still some problem with uart receive under heavy load, so change to a 2-byte ↵Paul Selkirk
receive buffer with half-complete callbacks, and raise the dma priority.
2016-09-01"make clean" needs to use "rm -f" to avoid gratuitous failures.Rob Austein
2016-07-21Use a fresh port of libcli, which retains more of the original API.Paul Selkirk
2016-07-06Fix the way code is commented out, to avoid compiler warnings.Paul Selkirk
2016-07-06Simplify library Makefiles by using symbols defined in top-level Makefile, ↵Paul Selkirk
rather than re-deriving them.
2016-06-25Split LIB*_DIR into _SRC and _BLD.Paul Selkirk
Also rename all instances of GNUmakefile to Makefile.

2016-06-23Drag in libhal update.Rob Austein
2016-06-23Drag submodule updates into sw/stm32.Rob Austein
2016-06-21Update sw/stm32 to track recent subrepository commits, since without them it ↵Rob Austein
no longer compiles (sigh).
2016-06-14Pull in sw/libhal CLIENT_TRANSPORT makefile fix.Rob Austein
2016-06-14Pull libhal changes into stm32 subrepo.Rob Austein
2016-06-14Bring sw/stm32 super-repository up to date with the ten zillionRob Austein
commits which have been made in other repositories since the last time anybody bothered to synchronize this. Poster child for why this kind of recursive hairball belongs in release engineering rather than in source code repositories which are under active development, but that yak can wait a little while longer for its shave.
2016-06-13Only the HSM project needs the RTOS; most of the test projects can use the ↵Paul Selkirk
STM32 HAL code directly.
2016-06-13Add __end symbols for CCMRAM and SDRAM sections.Paul Selkirk
This lets us, say, use these sections for stack or heap.
