2021-10-20tests: acpi: update expected tables blobsIgor Mammedov
Update adds CPU entries to MADT/SRAT/FACP and DSDT to cover 288 CPUs. Notable changes are that CPUs with APIC ID 255 and higher use 'Processor Local x2APIC Affinity' structure in SRAT and "Device" element in DSDT.

2021-10-20tests: qtest: add qtest_has_accel() to check if tested binary supports ↵Igor Mammedov
accelerator Currently it is not possible to create tests that have KVM as a hard requirement on a host that doesn't support KVM for tested target binary (modulo going through the trouble of compiling out the offending test case). Following scenario makes test fail when it's run on non x86 host: qemu-system-x86_64 -enable-kvm -M q35,kernel-irqchip=on -smp 1,maxcpus=288 This patch introduces qtest_has_accel() to let users check if accel is available in advance and avoid executing non run-able test-cases. It implements detection of TCG and KVM only, the rest could be added later on, when we actually start testing them in qtest.

This joins together two patch series: [PATCH v2 00/15] bsd-user: misc cleanup for aarch64 import Prepare for aarch64 support (the next architecture to be upstreamed). As the aarch64 emulation is more complete, it relies on a number of different items. In some cases, I've pulled in the full support from bsd-user fork. In other cases I've created a simple stub (as is the case for signals, which have independent changes pending, so I wanted to be as minimal as possible. Since all pre-12.2 support was purged from the bsd-user fork, go ahead and remove it here. FreeBSD 11.x goes ouft of support at the end of the month. Remove what little multi-version support that's in upstream. and [PATCH v3 0/9] bsd-user mmap fixes This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug fixes pulled in from linux-user, as well as some newer fixes to adress bugs found in check-tcg and recent FreeBSD developments. There are also a couple of style commits. Updated to migrate debugging to qemu_log. as well as a couple of minor rebase tweaks.
