Hi Will, sorry for the late reply but I am on sabbatical :) On 9/29/21 5:49 PM, Will Deacon wrote:
I'm surprised not to see any update to: Documentation/arm64/memory-tagging-extension.rst particularly regarding the per-cpu preferred tag checking modes. Is asymmetric mode not supported there?
The document that you are pointing out covers the userspace support, this series introduces the in-kernel support only for asymmetric MTE. The userspace bits for asymm will be added with a future series. The confusion comes from the fact, as Peter correctly pointed already, that I forgot to mention this vital info in the cover letter. Sorry about that I will make sure that this is addressed in v2. Thanks!
