Hi,
Major Changes from v5:
- Addressed comments from Robin & Lorenzo.
: Moved iort_parse_rmr() to acpi_iort_init() from
iort_init_platform_devices().
: Removed use of struct iort_rmr_entry during the initial
parse. Using struct iommu_resv_region instead.
: Report RMR address alignment and overlap errors, but continue.
: Reworked arm_smmu_init_bypass_stes() (patch # 6).
- Updated SMMUv2 bypass SMR code. Thanks to Jon N (patch #8).
- Set IOMMU protection flags(IOMMU_CACHE, IOMMU_MMIO) based
on Type of RMR region. Suggested by Jon N.I use the updated firmware from Huiqiang(Cced), tested on my Kunpeng 920 server, the 3408iMRraid and 3416iMRraid can work as expected with SMMUv3 enabled.
