Thanks! I've tentatively managed to queue all of this apart from the last patch, since that relies on some pasid symbols being exported from the PCI core when building the driver as a module with PCI_PASID=y. Please can you look at the rest of things here?: https://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git/log/?h=for-joerg/arm-smmu/updates > Still missing and will be submitted as follow-up patches: > * write STE.V with WRITE_ONCE() (patch 7) I've hacked that one up myself. > * batch submission of CD invalidation (patch 7) That can be 5.7 material. > * Remove WARN_ON_ONCE() in add_device() (patch 13) > Pending Robin's input. I've written that one too, but we'll see what Robin says. The question now is which commit do I tag in the branch above :) Will _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
