The performance number can be found in PATCH 2, please review when you free, thanks. Changes v2 -> v3: - make first_pte_in_page() neater [Baolu] - remove meaningless BUG_ON() in __domain_mapping() [Baolu] Changes v1 -> v2: - Fix compile warning on i386 [Baolu] Longpeng(Mike) (2): iommu/vt-d: convert the return type of first_pte_in_page to bool iommu/vt-d: avoid duplicated removing in __domain_mapping drivers/iommu/intel/iommu.c | 11 ++++++----- include/linux/intel-iommu.h | 10 ++++++++-- 2 files changed, 14 insertions(+), 7 deletions(-) -- 1.8.3.1 _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
