Support for parsing the topology on AMD/Hygon processors using CPUID leaf 0xb
was added in
3986a0a805 ("x86/CPU/AMD: Derive CPU topology from CPUID function 0xB when available").
In an effort to keep all the topology parsing bits in one place, this commit
also introduced a pseudo dependency on the TOPOEXT feature to parse the CPUID
leaf 0xb.
The TOPOEXT feature (CPUID 0x80000001 ECX[22]) advertises the support for
Cache Properties leaf 0x8000001d and the CPUID leaf 0x8000001e EAX for
"Extended APIC ID" however support for 0xb was introduced alongside the x2APIC
support not only on AMD [1], but also historically on x86 [2].
Similar to 0xb, the support for extended CPU topology leaf 0x80000026 too does
not depend on the TOPOEXT feature.
The support for these leaves is expected to be confirmed by ensuring
leaf <= {extended_}cpuid_level
and then parsing the level 0 of the respective leaf to confirm EBX[15:0]
(LogProcAtThisLevel) is non-zero as stated in the definition of
"CPUID_Fn0000000B_EAX_x00 [Extended Topology Enumeration]
(Core::X86::Cpuid::ExtTopEnumEax0)" in Processor Programming Reference (PPR)
for AMD Family 19h Model 01h Rev B1 Vol1 [3] Sec. 2.1.15.1 "CPUID Instruction
Functions".
This has not been a problem on baremetal platforms since support for TOPOEXT
(Fam 0x15 and later) predates the support for CPUID leaf 0xb (Fam 0x17[Zen2]
and later), however, for AMD guests on QEMU, the "x2apic" feature can be
enabled independent of the "topoext" feature where QEMU expects topology and
the initial APICID to be parsed using the CPUID leaf 0xb (especially when
number of cores > 255) which is populated independent of the "topoext" feature
flag.
Unconditionally call cpu_parse_topology_ext() on AMD and Hygon processors to
first parse the topology using the XTOPOLOGY leaves (0x80000026 / 0xb) before
using the TOPOEXT leaf (0x8000001e).
While at it, break down the single large comment in parse_topology_amd() to
better highlight the purpose of each CPUID leaf.

Turns out that picking an idle CPU for floating interrupts has some
negative side effects. The guest will keep the IO workload on its CPU
and rather use an IPI from the interrupt CPU instead of moving workload.
For example a guest with 2 vCPUs and 1 fio process might run that fio on
vcpu1. If after diag500 both vCPUs are idle then vcpu0 is woken up. The
guest will then do an IPI from vcpu0 to vcpu1.
So lets change the heuristics and prefer the last CPU that went to
sleep. This one is likely still in halt polling and can be woken up
quickly.
This patch shows significant improvements in terms of bandwidth or
cpu consumption for fio and uperf workloads and seems to be a net
win.

The interrupt functionality is implemented through an irqchip, whose
operations are written with previous generation SoCs in mind and could
be reused. Since all Loongson SoCs with similar interrupt capability
(LS2K1500, LS2K2000) support byte-control mode, these operations are for
