This is an Armv9.0-A processor very similar to the Cortex-A710. The differences are: * no FEAT_EVT * FEAT_DGH (data gathering hint) * FEAT_NV (not yet implemented in QEMU) * Statistical Profiling Extension (not implemented in QEMU) * 48 bit physical address range, not 40 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed) * PMCR_EL0.N = 6 (always 6 PMU counters, not 20) Because it has 48-bit physical address support, we can use this CPU in the sbsa-ref board as well as the virt board.

The advice is always: use pauth-impdef=on. Our documentation even mentions it "by default" in docs/system/introduction.rst. Thus, we change the default to use impdef by default. This does not affect kvm or hvf acceleration, since pauth algorithm used is the one from host cpu. This change is retro compatible, in terms of cli, with previous versions, as the semantic of using -cpu max,pauth-impdef=on, and -cpu max,pauth-qarma3=on is preserved. The new option introduced in previous patch and matching old default is -cpu max,pauth-qarma5=on. It is retro compatible with migration as well, by defining a backcompat property, that will use qarma5 by default for virt machine <= 9.2. Tested by saving and restoring a vm from qemu 9.2.0 into qemu-master (10.0) for cpus neoverse-n2 and max.
