| | | | | | | | | | | | | | | | NULL is returned to Mapping when Operation is BusMasterCommonBuffer or BusMasterCommonBuffer64 in PeiIoMmuMap(). So Mapping == NULL is valid when calling PeiIoMmuUnmap(). 940dbd071e9f01717236af236740aa0da716805f wrongly changed EFI_SUCCESS to EFI_INVALID_PARAMETER when Mapping == NULL in PeiIoMmuUnmap().

* IntelSiliconPkg IntelVTdDxe: Fix flush cache issueStar Zeng2018-01-241-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The patch fixes flush cache issue in CreateSecondLevelPagingEntryTable(). We found some video cards still not work even they have been added to the exception list. In CreateSecondLevelPagingEntryTable(), the check "(BaseAddress >= MemoryLimit)" may be TRUE and "goto Done" will be executed, then the FlushPageTableMemory operations at the end of the function will be skipped. Instead of "goto Done", this patch uses "break" to break the for loops, then the FlushPageTableMemory operations at the end of the function could have opportunity to be executed. The patch also fixes a miscalculation for Lvl3End.

The system address map reported by the BIOS indicates what portions of this addresses are populated. The Host Address Width (HAW) of the platform is computed as (N+1), where N is the value reported in this field. For example, for a platform supporting 40 bits of physical addressability, the value of 100111b is reported in this field.

| | | | | | | | | | | | | | | This PEIM is to produce IOMMU_PPI, so that PEI device driver can have better DAM management. This PEIM will setup VTD PMR register to protect most DRAM. It allocates a big chunk DMA buffer in the entrypoint, and only use this buffer for DMA. Any other region is DMA protected.
