<span lang="EN-US">Hi all,<br>
<br>
Good news is that following three repos have been created by ops and should be ready for use!<br>
<br>
<a href="https://github.com/openjdk/riscv-port-jdk17u">https://github.com/openjdk/riscv-port-jdk17u</a><br>
<a href="https://github.com/openjdk/riscv-port-jdk11u">https://github.com/openjdk/riscv-port-jdk11u</a><br>
<a href="https://github.com/openjdk/riscv-port-jdk8u">https://github.com/openjdk/riscv-port-jdk8u</a><br>
<br>
They are seeded with jdk{17, 11, 8}u-dev repos respectively. <br>
We should start from riscv-port-jdk17u. And I have created a riscv-port branch in this repo for future 17u backporting work.
<br>
As mentioned by Lindenmaier Goetz, the initial backport should be restricted to the changes that are definitely needed to get it working.
<br>
Also, changes to shared code should be kept to a minimum. <br>
Please let me know if there are other things missed. <br>
<br>
Thanks,<br>
Fei Yang<br>
