In this situation we should do two things: 1. Tell guest to free allocated buffer, so there will be no memory leak for guest. 2. Tell OP-TEE that buffer allocation failed. To ask guest to free allocated buffer we should perform the same thing, as OP-TEE does - issue RPC request. This is done by filling request buffer (luckily we can reuse the same buffer, that OP-TEE used to issue original request) and then return to guest with special return code. Then we need to handle next call from guest in a special way: as RPC was issued by Xen, not by OP-TEE, it should be handled by Xen. Basically, this is the mechanism to preempt OP-TEE mediator. The same mechanism can be used in the future to preempt mediator during translation large (>512 pages) shared buffers.

This patch introduces a new 'libxl_passthrough' enumeration into libxl_domain_create_info. The value will be set by xl either when it parses a new 'passthrough' option in xl.cfg, or implicitly if there is passthrough hardware specified for the domain. If the value of the passthrough configuration option is 'disabled' then the XEN_DOMCTL_CDF_iommu flag will be clear in the xen_domctl_createdomain flags, thus allowing the toolstack to control whether the domain gets IOMMU mappings or not (where previously they were globally set). If the value of the passthrough configuration option is 'sync_pt' then a new 'iommu_opts' field in xen_domctl_createdomain will be set with the value XEN_DOMCTL_IOMMU_no_sharept. This will override the global default set in iommu_hap_pt_share, thus allowing the toolstack to control whether EPT sharing is used for the domain. If the value of passthrough is 'enabled' then xl will choose an appropriate default according to the type of domain and hardware support. NOTE: The 'iommu_memkb' overhead in libxl_domain_build_info will now only be set if passthrough is 'sync_pt' (or xl has chosen this mode as a default).

Fix this by reordering the code, and getting rid of the else: now if the "we are within an enum" branch decides that it's the end of the enum, it unsets $ei and we then immediately process the line as a "not within an enum" line - ie as the start of the next one.

This patch moves them there. NOTE: Disabling 'sharept' in the command line iommu options should really be hard error on ARM (as opposed to just being ignored), so define 'iommu_hap_pt_share' to be true for ARM (via ARM-selected CONFIG_IOMMU_FORCE_PT_SHARE).

Also don't tear down the tables again when the last device is de-assigned; defer that task until domain destruction. This allows the has_iommu_pt() helper and iommu_status enumeration to be removed. Calls to has_iommu_pt() are simply replaced by calls to is_iommu_enabled(). Remaining open-coded tests of iommu_hap_pt_share can also be replaced by calls to iommu_use_hap_pt(). The arch_iommu_populate_page_table() and iommu_construct() functions become redundant, as does the 'strict mode' dom0 page_list mapping code in iommu_hwdom_init(), and iommu_teardown() can be made static is its only remaining caller, iommu_domain_destroy(), is within the same source module. All in all, about 220 lines of code are removed from the hypervisor (at the expense of some additions in the toolstack). NOTE: This patch will cause a small amount of extra resource to be used to accommodate IOMMU page tables that may never be used, since the per-domain IOMMU-enable flag is currently set to the value of the global iommu_enable flag. A subsequent patch will add an option to the toolstack to allow it to be turned off if there is no intention to assign passthrough hardware to the domain. To account for the extra resource, 'iommu_memkb' has been added to domain_build_info. This patch sets it to a value calculated based on the domain's maximum memory when the P2M sharing is either not supported or globally disabled, or zero otherwise. However, when the toolstack option mentioned above is added, it will also be zero if the per-domain IOMMU-enable flag is turned off.

For both MSI and MSI-X we can determine how many interrupts could be set up at most. Tables allocated during ACPI table parsing, however, will (for now at least) continue to be set up to have maximum size. Note that until we would want to use sub-page allocations here there's no point checking whether both MSI and MSI-X are supported by a device - an order-0 allocation will fit the dual case in any event, no matter that the MSI-X vector count may be smaller than the MSI one. On my Rome system this reduces space needed from just over 1k pages to about 125.

For caller side simplicity have alloc_intremap_entry() return the maximum possible value upon allocation failure, rather than the first just out-of-bounds one. Have the involved functions already take all the subsequently needed arguments here already, to reduce code churn in the patch actually making the allocation size dynamic.

This mainly requires some care while freeing them, to avoid freeing memory blocks twice.

By delaying the table allocations for most cases, and doing them only when an actual device is known to be present at a given position, overall memory used for the tables goes down from over 500k pages to just over 1k (on my system having such ACPI table contents). Tables continue to get allocated right away for special entries (IO-APIC, HPET) as well as for alias IDs. While in the former case that's simply because there may not be any device at a given position, in the latter case this is to avoid having to introduce ref-counting of table usage. The change involves invoking iterate_ivrs_mappings(amd_iommu_setup_device_table) a second time, because the function now wants to be able to find PCI devices, which isn't possible yet when IOMMU setup happens very early during x2APIC mode setup. In this context amd_iommu_init_interrupt() gets renamed as well. The logic adjusting a DTE's interrupt remapping attributes also gets changed, such that the lack of an IRT would result in target aborted rather than non-remapped interrupts (should any occur). Note that for now phantom functions get separate IRTs allocated, as was the case before.
