Re: [OE-core] [meta-oe] [PATCH 1/2] Support for building on RISCV

[Ross Burton]

Can you resend these with better commit messages?

“Support for building on RISCV” doesn’t explain what is happening here.

“machine-sdk: add configuration for riscv64” does.

[meta-oe] [PATCH V2 1/2] Support bitbake compilation when the host is a RISCV platform

[cp0613]

From: Chen Pei <cp0613@linux.alibaba.com>

I have a RISCV board running Ubuntu, and then clone the bitbake, meta-oe... to compile, 
just like using yocto in ARM board, so I need to add machine-sdk:riscv64 to support it.

[Alexander Kanavin]

This is not what the commit actually contains. The commit adds a
riscv64 definition for a SDK host machine, and so the commit message
should say that.

"machine-sdk: add a risv64 definition"

The commit title is "Support bitbake compilation when the host is a
RISCV platform"

Imagine someone reading the commit log; will that title help them
understand that this is a meson fix, or what 'support' actually means?

It should be "meson: set dynamic-linker for riscv64 targets"
