2023-03-07gdbstub: move register helpers into standalone includeAlex Bennée
These inline helpers are all used by target specific code so move them out of the general header so we don't needlessly pollute the rest of the API with target specific stuff. Note we have to include cpu.h in semihosting as it was relying on a side effect before.

2023-02-28accel/tcg: Add 'size' param to probe_access_flags()Daniel Henrique Barboza
probe_access_flags() as it is today uses probe_access_full(), which in turn uses probe_access_internal() with size = 0. probe_access_internal() then uses the size to call the tlb_fill() callback for the given CPU. This size param ('fault_size' as probe_access_internal() calls it) is ignored by most existing .tlb_fill callback implementations, e.g. arm_cpu_tlb_fill(), ppc_cpu_tlb_fill(), x86_cpu_tlb_fill() and mips_cpu_tlb_fill() to name a few. But RISC-V riscv_cpu_tlb_fill() actually uses it. The 'size' parameter is used to check for PMP (Physical Memory Protection) access. This is necessary because PMP does not make any guarantees about all the bytes of the same page having the same permissions, i.e. the same page can have different PMP properties, so we're forced to make sub-page range checks. To allow RISC-V emulation to do a probe_acess_flags() that covers PMP, we need to either add a 'size' param to the existing probe_acess_flags() or create a new interface (e.g. probe_access_range_flags). There are quite a few probe_* APIs already, so let's add a 'size' param to probe_access_flags() and re-use this API. This is done by open coding what probe_access_full() does inside probe_acess_flags() and passing the 'size' param to probe_acess_internal(). Existing probe_access_flags() callers use size = 0 to not change their current API usage. 'size' is asserted to enforce single page access like probe_access() already does. No behavioral changes intended.

2022-10-26s390x: pv: Add dump supportJanosch Frank
Sometimes dumping a guest from the outside is the only way to get the data that is needed. This can be the case if a dumping mechanism like KDUMP hasn't been configured or data needs to be fetched at a specific point. Dumping a protected guest from the outside without help from fw/hw doesn't yield sufficient data to be useful. Hence we now introduce PV dump support. The PV dump support works by integrating the firmware into the dump process. New Ultravisor calls are used to initiate the dump process, dump cpu data, dump memory state and lastly complete the dump process. The UV calls are exposed by KVM via the new KVM_PV_DUMP command and its subcommands. The guest's data is fully encrypted and can only be decrypted by the entity that owns the customer communication key for the dumped guest. Also dumping needs to be allowed via a flag in the SE header. On the QEMU side of things we store the PV dump data in the newly introduced architecture ELF sections (storage state and completion data) and the cpu notes (for cpu dump data). Users can use the zgetdump tool to convert the encrypted QEMU dump to an unencrypted one.
