2023-02-07hw/riscv: change riscv_compute_fdt_addr() semanticsDaniel Henrique Barboza
As it is now, riscv_compute_fdt_addr() is receiving a dram_base, a mem_size (which is defaulted to MachineState::ram_size in all boards) and the FDT pointer. And it makes a very important assumption: the DRAM interval dram_base + mem_size is contiguous. This is indeed the case for most boards that use a FDT. The Icicle Kit board works with 2 distinct RAM banks that are separated by a gap. We have a lower bank with 1GiB size, a gap follows, then at 64GiB the high memory starts. MachineClass::default_ram_size for this board is set to 1.5Gb, and machine_init() is enforcing it as minimal RAM size, meaning that there we'll always have at least 512 MiB in the Hi RAM area. Using riscv_compute_fdt_addr() in this board is weird because not only the board has sparse RAM, and it's calling it using the base address of the Lo RAM area, but it's also using a mem_size that we have guarantees that it will go up to the Hi RAM. All the function assumptions doesn't work for this board. In fact, what makes the function works at all in this case is a coincidence. Commit 1a475d39ef54 introduced a 3GB boundary for the FDT, down from 4Gb, that is enforced if dram_base is lower than 3072 MiB. For the Icicle Kit board, memmap[MICROCHIP_PFSOC_DRAM_LO].base is 0x80000000 (2 Gb) and it has a 1Gb size, so it will fall in the conditions to put the FDT under a 3Gb address, which happens to be exactly at the end of DRAM_LO. If the base address of the Lo area started later than 3Gb this function would be unusable by the board. Changing any assumptions inside riscv_compute_fdt_addr() can also break it by accident as well. Let's change riscv_compute_fdt_addr() semantics to be appropriate to the Icicle Kit board and for future boards that might have sparse RAM topologies to worry about: - relieve the condition that the dram_base + mem_size area is contiguous, since this is already not the case today; - receive an extra 'dram_size' size attribute that refers to a contiguous RAM block that the board wants the FDT to reside on. Together with 'mem_size' and 'fdt', which are now now being consumed by a MachineState pointer, we're able to make clear assumptions based on the DRAM block and total mem_size available to ensure that the FDT will be put in a valid RAM address.

2023-02-07hw/riscv: split fdt address calculation from fdt loadDaniel Henrique Barboza
A common trend in other archs is to calculate the fdt address, which is usually straightforward, and then calling a function that loads the fdt/dtb by using that address. riscv_load_fdt() is doing a bit too much in comparison. It's calculating the fdt address via an elaborated heuristic to put the FDT at the bottom of DRAM, and "bottom of DRAM" will vary across boards and configurations, then it's actually loading the fdt, and finally it's returning the fdt address used to the caller. Reduce the existing complexity of riscv_load_fdt() by splitting its code into a new function, riscv_compute_fdt_addr(), that will take care of all fdt address logic. riscv_load_fdt() can then be a simple function that just loads a fdt at the given fdt address. We're also taken the opportunity to clarify the intentions and assumptions made by these functions. riscv_load_fdt() is now receiving a hwaddr as fdt_addr because there is no restriction of having to load the fdt in higher addresses that doesn't fit in an uint32_t.

2023-02-06virtio-mem: Migrate immutable properties earlyDavid Hildenbrand
The bitmap and the size are immutable while migration is active: see virtio_mem_is_busy(). We can migrate this information early, before migrating any actual RAM content. Further, all information we need for sanity checks is immutable as well. Having this information in place early will, for example, allow for properly preallocating memory before touching these memory locations during RAM migration: this way, we can make sure that all memory was actually preallocated and that any user errors (e.g., insufficient hugetlb pages) can be handled gracefully. In contrast, usable_region_size and requested_size can theoretically still be modified on the source while the VM is running. Keep migrating these properties the usual, late, way. Use a new device property to keep behavior of compat machines unmodified. Reviewed-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

2023-02-06migration/savevm: Allow immutable device state to be migrated early (i.e., ↵David Hildenbrand
before RAM) For virtio-mem, we want to have the plugged/unplugged state of memory blocks available before migrating any actual RAM content, and perform sanity checks before touching anything on the destination. This information is immutable on the migration source while migration is active, We want to use this information for proper preallocation support with migration: currently, we don't preallocate memory on the migration target, and especially with hugetlb, we can easily run out of hugetlb pages during RAM migration and will crash (SIGBUS) instead of catching this gracefully via preallocation. Migrating device state via a VMSD before we start iterating is currently impossible: the only approach that would be possible is avoiding a VMSD and migrating state manually during save_setup(), to be restored during load_state(). Let's allow for migrating device state via a VMSD early, during the setup phase in qemu_savevm_state_setup(). To keep it simple, we indicate applicable VMSD's using an "early_setup" flag. Note that only very selected devices (i.e., ones seriously messing with RAM setup) are supposed to make use of such early state migration. While at it, also use a bool for the "unmigratable" member.

2023-02-04tcg: Split out tcg_gen_nonatomic_cmpxchg_i{32,64}Richard Henderson
Normally this is automatically handled by the CF_PARALLEL checks with in tcg_gen_atomic_cmpxchg_i{32,64}, but x86 has a special case of !PREFIX_LOCK where it always wants the non-atomic version. Split these out so that x86 does not have to roll its own. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2023-02-04include/qemu/int128: Use Int128 structure for TCIRichard Henderson
We are about to allow passing Int128 to/from tcg helper functions, but libffi doesn't support __int128_t, so use the structure. In order for atomic128.h to continue working, we must provide a mechanism to frob between real __int128_t and the structure. Provide a new union, Int128Alias, for this. We cannot modify Int128 itself, as any changed alignment would also break libffi.

2023-02-03hw/arm/virt: Consolidate GIC finalize logicAlexander Graf
Up to now, the finalize_gic_version() code open coded what is essentially a support bitmap match between host/emulation environment and desired target GIC type. This open coding leads to undesirable side effects. For example, a VM with KVM and -smp 10 will automatically choose GICv3 while the same command line with TCG will stay on GICv2 and fail the launch. This patch combines the TCG and KVM matching code paths by making everything a 2 pass process. First, we determine which GIC versions the current environment is able to support, then we go through a single state machine to determine which target GIC mode that means for us. After this patch, the only user noticable changes should be consolidated error messages as well as TCG -M virt supporting -smp > 8 automatically.
