| 2020-01-21 | New FMC settings for STM32.fmc_clk | Pavel V. Shatov (Meister) | |
| 2019-01-31 | Updated FMC initialization code to match changes in FMC arbiter. | Pavel V. Shatov (Meister) | |
| 2018-12-12 | Rebase branch 'fmc_clk' of git.cryptech.is:sw/stm32 from master | Paul Selkirk | |
| 2018-12-12 | Whack various bits of sw/stm32 test code to compile on fmc_clk branch. | Rob Austein | |
| 2018-12-12 | Changed FMC initialization code to match the new sync FMC arbiter. Removed | Pavel V. Shatov (Meister) | |
| unnecessary code (no more double read, yay!) | |||
| 2018-12-05 | Tell 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. | |||
| 2018-12-03 | Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in. | Paul Selkirk | |
| 2018-12-02 | Clean up the profiling code to the point where I stand a chance of | Paul 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. | |||
| 2018-11-26 | Add loop unrolling to bring the profilable mem* functions closer to | Paul 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. | |||
| 2018-11-14 | Increase cli task, and move it to SDRAM, because main RAM is getting full. | Paul Selkirk | |
| 2018-09-05 | When erasing the whole keystore, optionally preserve the login PINs. | Paul Selkirk | |
| 2018-09-04 | Make 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. | |||
| 2018-08-27 | Add startup delay to let fmc bus settle | Paul Selkirk | |
| 2018-07-25 | Merge branch 'hashsig' | Paul Selkirk | |
| 2018-07-24 | Add dummy hal_free_static_memory to cli-test, to avoid a link error. | Paul Selkirk | |
| We really ought to rototill cli-test, but not today. | |||

| 2018-07-07 | Changed FMC initialization code to match the new sync FMC arbiter. Removed | Pavel V. Shatov (Meister) | |

| 2018-05-27 | Script to run a test with HSM profiling. | Rob Austein | |
| 2018-05-27 | FMC cleanup: constification, gratuitous pointer. | Rob Austein | |
| 2018-05-27 | Convert FMC I/O functions to static inline. | Rob Austein | |
| fmc_read_32() and fmc_write_32() get called often enough that it's worth eliminating unnecessary function call overhead. | |||
| 2018-05-23 | Simplify FMC I/O code. | Rob Austein | |
| We're no longer using a preemptive multitasker, and we're on the Alpha, not the old bridge board, so all we really need to do is read or write one word at a time via a pointer then wait for the GPIO idle pin to light. Well, other than needing to read twice because of a known hardware problem with the STM32. So we dont need to fiddle with IRQ, or use the CMSIS SRAM lock, or.... | |||
| 2018-05-20 | Mutex for RSA blinding factors cache. | Rob Austein | |
| 2018-05-01 | Update and expand README | Paul Selkirk | |
| 2018-05-01 | Fix mbed vpath not to use explicit (and wrong) paths | Paul Selkirk | |
| 2018-04-19 | Rebase hashsig from master | Paul Selkirk | |
| 2018-04-19 | Reconstruct the hashsig hash tree(s) on device restart. | Paul Selkirk | |
| This can take long enough (several minutes for h=10) that we do it in a background task, which is then converted to an RPC dispatch task. Also add a very limited form of free(), to free the topmost allocation in the sdram "heap". I don't want to deal with real heap management, but I do want to be able to recover memory upon deleting a hashsig key, if it's easy to do so. | |||
| 2018-04-19 | Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txt | Paul Selkirk | |
| 2018-04-19 | Cleanup: 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. | |||

| 2017-12-14 | Revert a clean up 'fix' which actually broke FPGA upload. | Paul Selkirk | |
| 2017-10-17 | Overhaul UART API | Paul Selkirk | |
| MGMT is the default UART, and no one should have to explicitly refer to the UART unless they need USER (hsm.c:hal_serial_send_char). The default UART is now exposed in the header file, so that the default-using functions can be macros, which saves a few bytes in code space, and a few microseconds in function call overhead. | |||
| 2017-10-15 | Cleanup: All drivers return HAL_StatusTypeDef rather than magic values. | Paul Selkirk | |
| Note: This affects libhal/ks_token.c, which uses the keystore driver directly. | |||
| 2017-10-11 | Cleanup 'unused parameter' warnings, a couple of which are actual coding errors. | Paul Selkirk | |
| 2017-10-11 | Cleanup: signed/unsigned mismatches, mostly in loop counters | Paul Selkirk | |
| 2017-10-11 | Cleanup: Remove useless (unsigned < 0) test. | Paul Selkirk | |
| 2017-09-21 | cleanup | Paul Selkirk | |
| 2017-09-21 | Make fmc-test less chatty. | Paul Selkirk | |
| 2017-09-07 | Rebase branch 'profiling' from master | Paul Selkirk | |
| 2017-09-07 | Add task_yield_maybe | Paul Selkirk | |
| 2017-09-07 | Duh, actually build task_metrics | Paul Selkirk | |
| 2017-09-07 | Sigh, right offset for the wrong register. Get the PC (the address we | Paul 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. | |||
| 2017-09-07 | Correct 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. | |||
| 2017-09-07 | Port profiling code, using a new SysTick hook and new CLI commands. | Paul Selkirk | |
| 2017-09-07 | Copy profiling code from MCUOnEclipse. | Paul Selkirk | |
| 2017-09-07 | Add some task metrics. | Paul Selkirk | |
| 2017-08-31 | Cleanup | Paul Selkirk | |
| 2017-08-31 | Withdraw 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(). | |||
