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.
