what is this licence? Is it even Apache compatible? we need to add license guard to this code
|
It's some kind of custom license, I think we should add "ALLOW_CUSTOM_COMPONENTS" or something like that for such strange cases |
Thanks! I have updated a README about testing module and how to test. |
I update Apache-2.0 License for Nuttx and add reference from source file |
|
@ThePassionate You can't relicense this file. This license doesn't appear to be compatible with Apache. EDIT: the license must remain as it was and the compilation must be guarded by Also nuttx doesn't use README anymore, please move this to nuttx/Documentation |
@ThePassionate we deprecated README files some years ago, all Documentation for nuttx and nuttx-apps should be created as ReStructuredText at nuttx/Documentation/ Please move it to there |

@ThePassionate please create the Documentation file at https://nuttx.apache.org/docs/latest/applications/benchmarks/index.html
Thanks! I didn't know the document path was in the Nuttx repository. I was searching in the current directory and only wrote the README because I couldn't find a suitable path. Thank you for your patience！ |
so should I add this license KCONFIG in this patch? it looks good to me. |
I get it ! Let me try |
please review apache/nuttx#18017 @acassis @raiden00pl Thanks! |
|
@jerpelea seems like there is not an official SPDX definition for Whetstone benchmark, how can I suggest this license to them: SPDX-License-Identifier: LicenseRef-Painter-Engineering-Whetstone |

Done. Thanks again! |

@ThePassionate please rebase your change |
Add the Whetstone floating-point benchmark to NuttX applications. The Whetstone benchmark is a widely-used tool for evaluating FPU (floating-point unit) performance. This benchmark is ported from netlib.org whetstone.c which has a custom permissive license requiring attribution. Therefore it depends on ALLOW_CUSTOM_PERMISSIVE_COMPONENTS. Usage: whetstone [loops] Signed-off-by: makejian <[email protected]>
Change FPU benchmark timing from seconds to milliseconds for better accuracy. This allows for more precise measurement of test cycles, especially for shorter test runs that previously completed within a single second. Signed-off-by: makejian <[email protected]>

Benchmarks: Add Whetstone FPU Benchmark with Enhanced Timing
Summary
This PR adds the Whetstone floating-point benchmark to NuttX applications. The Whetstone benchmark is a widely-used tool for evaluating FPU (floating-point unit) performance. The implementation includes timing enhancements that provide millisecond-level precision for more accurate performance measurement.
