commit 6ea3e32a5e0e6ba0f568aa5fd5a6b016c0c21ca0 Author: Bertrand Marquis <bertrand.marquis@xxxxxxx> AuthorDate: Thu Dec 17 15:38:08 2020 +0000 Commit: Stefano Stabellini <sstabellini@xxxxxxxxxx> CommitDate: Mon Jan 4 11:27:32 2021 -0800 xen/arm: Activate TID3 in HCR_EL2 Activate TID3 bit in HCR register when starting a guest. This will trap all coprecessor ID registers so that we can give to guest values corresponding to what they can actually use and mask some features to guests even though they would be supported by the underlying hardware (like SVE or MPAM).
