MemMapEntries initialized in this array have a static size and base address. - extended_memmap, only initialized with entries located after the RAM. MemMapEntries initialized in this array only get their size initialized. Their base address is dynamically computed depending on the the top of the RAM, with same alignment as their size. Eventually base_memmap entries are copied into the extended_memmap array. Using two separate arrays however clarifies which entries are statically allocated and those which are dynamically allocated. This new split will allow to grow the RAM size without changing the description of the high IO entries. We introduce a new virt_set_memmap() helper function which "freezes" the memory map. We call it in machvirt_init as memory attributes of the machine are not yet set when virt_instance_init() gets called. The memory map is unchanged (the top of the initial RAM still is 256GiB). Then come the high IO regions with same layout as before.

This patch modifies the virt_set_memmap() function, which freezes the memory map, so that the high IO range base becomes floating, located after the initial RAM and the device memory. The function computes - the base of the device memory, - the size of the device memory, - the high IO region base - the highest GPA used in the memory map. Entries of the high IO region are assigned a base address. The device memory is initialized. The highest GPA used in the memory map will be used at VM creation to choose the requested IPA size. Setting all the existing highmem IO regions beyond the RAM allows to have a single contiguous RAM region (initial RAM and possible hotpluggable device memory). That way we do not need to do invasive changes in the EDK2 FW to support a dynamic RAM base. Still the user cannot request an initial RAM size greater than 255GB.

The total code coverage they give is: Overall coverage rate: lines......: 11.2% (59584 of 530123 lines) functions..: 15.0% (7436 of 49443 functions) branches...: 6.3% (19273 of 303933 branches) We already get pretty close to that with the machine_aarch64_virt tests which only does one full boot (~120s vs ~600s) of alpine. We expand the kernel+initrd boot (~8s) to test both GICs and also add an RNG device and a block device to generate a few IRQs and exercise the storage layer. With that we get to a coverage of: Overall coverage rate: lines......: 11.0% (58121 of 530123 lines) functions..: 14.9% (7343 of 49443 functions) branches...: 6.0% (18269 of 303933 branches) which I feel is close enough given the massive time saving.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA". ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to be zero(Do not abort incoming transactions). Other fields have default values of Use Incoming. If UPDATE is not set, the write is ignored. This is the only permitted behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure) As this patch adds a new state to the SMMU (GBPA), it is added in a new subsection for forward migration compatibility. GBPA is only migrated if its value is different from the reset value. It does this to be backward migration compatible if SW didn't write the register.
