Since this flag is only available for domain created by XEN, not exposed to the toolstack, we name it with extra "INTERNAL" to distinguish from other public XEN_DOMCTL_CDF_xxx flags, and add comments to warn developers not to accidently use its bitfield when introducing new XEN_DOMCTL_CDF_xxx flag. Refine is_domain_direct_mapped to check whether the flag XEN_DOMCTL_CDF_INTERNAL_directmap is set.

In order not to bring a lot of duplicate codes, and also to make the whole code more readable, this commit extracts common codes into two new helpers parse_static_mem_prop and acquire_static_memory_bank.

charset="utf-8" Cases where domU needs direct-map memory map: * IOMMU not present in the system. * IOMMU disabled if it doesn't cover a specific device and all the guests are trusted. Thinking a mixed scenario, where a few devices with IOMMU and a few without, then guest DMA security still could not be totally guarantee= d. So users may want to disable the IOMMU, to at least gain some performance improvement from IOMMU disabled. * IOMMU disabled as a workaround when it doesn't have enough bandwidth. To be specific, in a few extreme situation, when multiple devices do DMA concurrently, these requests may exceed IOMMU's transmission capacity. * IOMMU disabled when it adds too much latency on DMA. For example, TLB may be missing in some IOMMU hardware, which may bring latency in DMA progress, so users may want to disable it in some realtime scenario. * Guest OS relies on the host memory layout This commit introduces a new helper allocate_static_memory_11 to allocate static memory as guest RAM for direct-map domain. For now, direct-map is only available when statically allocated memory is used for the domain, that is, "xen,static-mem" must be also defined in the domain configuration.

This patch changes the behavior so that native addresses are used for all domains that are direct-mapped. NEW VGIC has different naming schemes, like referring distributor base address as vgic_dist_base, other than the dbase.

charset="utf-8" From: Stefano Stabellini Today we use native addresses to map the GICv3 for Dom0 and fixed addresses for DomUs. This patch changes the behavior so that native addresses are used for all domain which is using the host memory layout Considering that DOM0 may not always be directly mapped in the future, this patch introduces a new helper "domain_use_host_layout()" that wraps both two check "is_domain_direct_mapped(d) || is_hardware_domain(d)" for more flexible usage.

charset="utf-8" From: Stefano Stabellini We always use a fix address to map the vPL011 to domains. The address could be a problem for direct-map domains. So, for domains that are directly mapped, reuse the address of the physical UART on the platform to avoid potential clashes. Do the same for the virtual IRQ number: instead of always using GUEST_VPL011_SPI, try to reuse the physical SPI number if possible.
