[PATCH V4 OLK-6.6] iommu/arm-smmu-v3: Add a SYNC command to avoid broken page table prefetch
by Zhang Zekun 26 Dec '23

26 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8QSLV CVE: NA ----------------------------------------------- On Hisilicon LINXICORE9100 cores, SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. If the SMMU works in terminate mode, transactions which occur fake pagefaults will be aborted, and could result in unexpected errors. To fix this problem, we need to add a SYNC command after smmu has map a iova, then smmu will always try to get the newest PTE.
