Hi Jean/zhangfei,
Is it possible to have a branch with minimum required SVA/UACCE related

patches

that are already public and can be a "stable" candidate for future respin

of

Eric's series?

Please share your thoughts.

By "stable" you mean a fixed branch with the latest SVA/UACCE patches
based on mainline?

Yes.

 The uacce-devel branches from

quoted

https://github.com/Linaro/linux-kernel-uadk do provide this at the moment
(they track the latest sva/zip-devel branch
https://jpbrucker.net/git/linux/ which is roughly based on mainline.)

As I plan to respin shortly, please could you confirm the best branch to
rebase on still is that one (uacce-devel from the linux-kernel-uadk git
repo). Is it up to date? Commits seem to be quite old there.

I think it is the uacce-devel-5.11 branch, but will wait for Jean or Zhangfei
to confirm.

Thanks,
Shameer

Thanks

Thanks.

Hi Eric,

Could you please take a look at the above branches and see whether it make

sense

quoted

to rebase on top of either of those?

From vSVA point of view, it will be less rebase hassle if we can do that.

Sure. I will rebase on top of this ;-)

Thanks
