Daniel, It is really good. For patch driver and new kernel buiding, I cc Dann on the mail too, he is our engineer for this enablement project with Hisilicon. This is pearl kernel was build by him too.
Dann, Can you patch and build out a new kernel for us or help Daniel to build a new testing kernel. For the new kernel install, I should be able to set it up. thanks, Mao On Thu, Jun 1, 2017 at 7:56 PM, Daniel Axtens <daniel.axt...@canonical.com> wrote: > Ok, so I think part of the problem is that the kernel hibmc driver needs > to use a set_busid function from the drm core.
