Kernel 6.9 released
Closed this issue · 4 comments
Hello,
question. Does Kernel 6.9 include the necessary patches (IOMMU SVA) or does it still require a custom kernel?
Thx

(I'll write a followup as soon as I have a working set.)
I've been trying to track when this is mainlined as well, and from what I can tell 6.10 is the most likely version to contain all the necessary patches. In fact I think last week's 6.10-rc1 (probably) has all these patches.
Part 4 (of 4) of the patch series (ie, the patches listed above) was applied on Apr 18 and got pulled into Linus's tree about 2 weeks ago.
Yes, 6.10 should have all the patches we need. We're internally testing 6.10. We'll update this repo when we complete the test.

If we can work with an unpatched upstream 6.10 kernel, that would of course be better.
