| 2017-03-01 | led_fade: Add NO_INIT flag to keep default clock frequency and UART ↵ | Megan Wachs | |
| configurations. | |||
| 2017-03-01 | Add a 'performance counters' demo. | Megan Wachs | |
| 2017-02-02 | Merge pull request #50 from sifive/common_plic | Megan Wachs | |
| FE-203 Move plic_driver code to a common location. | |||
| 2017-02-02 | prci: Clean up the hfrosc-driven-pll FPU testing. | Megan Wachs | |
| 2017-02-02 | prci: Simplify the targeted f_cpu function by measuring HFROSC frequency ↵ | Megan Wachs | |
| first, then using it as the PLL source. This is also safer as it is less risk of using PLL out of its range. | |||
| 2017-02-02 | Merge remote-tracking branch 'origin/master' into common_plic | Megan Wachs | |

| 2017-02-02 | help: use punctuation consistently | Megan Wachs | |
| 2017-02-02 | help: Re-organized the Makefile help, and updated the README to use the ↵ | Megan Wachs | |
| already existing 'uninstall' target to remove and reinstall tools. | |||
| 2017-02-01 | PRCI: This doesn't exist on the Arty and potentially other devices, so ↵ | Megan Wachs | |
| exclude it if there is not PRCI_BASE_ADDR on the system. | |||
| 2017-02-01 | PRCI: add control for the target CPU frequency (to allow a minimum, maximum, ↵ | Megan Wachs | |
| or closest match) | |||
| 2017-02-01 | Additional PRCI driver support. Make the code usable by C++ programs as well. | Megan Wachs | |
| 2017-01-31 | add a 'driver' common PRCI functions. | Megan Wachs | |

| 2017-01-12 | Use HTTPS when possible and speedup the first build (#40) | dns2utf8 | |
| * Use HTTPS when ever possible and speedup the first build * Use HTTPS for submodules * Change $(nproc) to a text * minor grammar changes | |||
| 2017-01-11 | Merge pull request #45 from sifive/double_tap_dontboot | Megan Wachs | |
| Add the 'bootloader' which ships on HiFive1 Boards. | |||
| 2017-01-11 | reduce code duplication and apply the same flags to Arty board | mwachs5 | |
| 2017-01-11 | double_tap_dontboot: Clean up indentation | mwachs5 | |
| 2017-01-11 | Spaces, not tabs. | mwachs5 | |

| Benchmarking | |||

| 2017-01-03 | Add CoreMark build skeleton | Andrew Waterman | |
| 2017-01-03 | Compile Dhrystone without RVC | Andrew Waterman | |
| Branch target misalignment reduces performance by about 10%. | |||
| 2017-01-03 | Regularize timing code | Andrew Waterman | |
| Provide get_timer_value() and get_timer_freq() and use them. On Arty, they use mcycle and the known-fixed core frequency, whereas on HiFive1 they use mtime and the known-fixed mtime frequency. | |||
| 2017-01-03 | Improve HiFive1 CPU frequency measurement routine | Andrew Waterman | |
| - Warm up I$ first. - Correct for integer division truncation error. - Wait for an RTC clock edge before starting the timing loop, which removes an error proportional to the number of loop iterations, allowing us to run for far less time. | |||
| 2017-01-03 | Keep mtvec 4-byte aligned | Andrew Waterman | |
| 2017-01-03 | Merge pull request #37 from NonerKao/master | Richard Xia | |
| Fixes in the root makefile | |||
| 2017-01-04 | Fixes in the root makefile | Quey-Liang Kao | |
| Each cd command in the targets software, software_clean, and dasm is unnecessary. Also, fixes from make to $(MAKE) help the readability of build/dry-run output. | |||
| 2016-12-24 | Merge pull request #33 from sifive/verify_openocd_flash | Megan Wachs | |
| Bump OpenOCD to pick up corrected malloc in Flashing code. | |||
| 2016-12-24 | Bump OpenOCD to pick up corrected malloc in Flashing code. Add 'verify' to ↵ | mwachs5 | |
| ensure Flash is loaded correctly. | |||
| 2016-12-20 | Separate .text.unlikely and .text.startup from .text | Andrew Waterman | |
| This improves the instruction stream's spatial locality. | |||
| 2016-12-20 | Avoid jal to weak symbols | Andrew Waterman | |
| The symbol may be overridden and end up out of range of JAL. | |||
