I... think we're at the very least presenting a leaf 8000_001E while identifying the processor as an Intel CPU.. cpu_topo_clear here includes all leaves mentioned in TopoKind, which is all of B, 1F, and 8000001E. we do nothing for leaf 1F but we always insert a leaf for Ext1E which should fix up the extended leaf identifier to at least 8000001E and make it visible on Intel.

I don't see where we set cpu_topo_populate in the bits I'd linked above so maybe the question is why do any of the TopoKind-mentioned leaves get filled out.

I don't know what happens over on the guest side when this happens but it seems pretty wrong to do. Haven't tried this on hardware yet but should be easy to check quickly..

this does not reproduce on Intel with propolis-standalone, but does with propolis-server (on an E5-2697v4). there are a few puzzlers here. most immediately, the issue is that at the point of panic we've got:

[0]> ::walk cpu | ::print cpu_t cpu_m.mcpu_cpi | ::print struct cpuid_info cpi_coreid
cpi_coreid = 0
cpi_coreid = 0
cpi_coreid = 0
cpi_coreid = 0

so all four threads think are allegedly on the same physical processor core. they've got distinct APIC IDs as you'd hope:

[0]> ::walk cpu | ::print cpu_t cpu_m.mcpu_cpi | ::print struct cpuid_info cpi_apicid
cpi_apicid = 0
cpi_apicid = 0x1
cpi_apicid = 0x2
cpi_apicid = 0x3

at some point we're just deciding they're all.. the same. this points towards somewhere around cpuid_basic_topology/cpuid_intel_ncores/cpuid_intel_getids.

pulling out cpuid-queries.d there are some odd lines..

this turns out to be an issue similar to #915. collect_cpuid doesn't know leaf 4 has subleaves, so we grab the first subleaf, stuff it back into bhyve as a leaf in explicit CPUID config, at which point bhyve dutifully provides it for all subleaves. so that's not great. the leaf itself is weird and is how we end up believing that the CPU has 4-way SMT.

leaf 4 eax bits 31-26 are the max "number of addressable IDs for processor cores in the physical package" (minus one), and 0x00000121 >> 26 is, erm, 0, reporting that there is one processor core in the package. at the same time in cpuid_intel_ncores we observe that HTT is set, so we get a thread count from leaf 1 ebx bits 32-16:

CPUID query: leaf/subleaf 0x00000001/0x00000000, returns rax = 0x000406f1, rbx = 0x03040800, rcx = 0xfeda3203, rdx = 0x1f8bfbff

or .. 4 on my VM. and so we've got four threads, one core because of the weird leaf 4, and that's 4-way SMT.

bhyve should be setting leaf 4 up reasonably, though: https://code.illumos.org/plugins/gitiles/illumos-gate/+/refs/heads/master/usr/src/uts/intel/io/vmm/vmm_cpuid.c#868 implies the VM topology is in fact one core with four threads.

this is all important, but i'd expect we use leaf B for this, not leaves 4 and 1. illumos calls cpuid_leafB_getids first and only uses these leaves if that did not succeed. so what's leaf B doing weird?

well, it's just zero:

CPUID query: leaf/subleaf 0x0000000b/0x00000000, returns rax = 0x00000000, rbx = 0x00000000, rcx = 0x00000000, rdx = 0x00000000
CPUID query: leaf/subleaf 0x0000000b/0x00000000, returns rax = 0x00000000, rbx = 0x00000000, rcx = 0x00000000, rdx = 0x00000000

this is strange too. here's part of cpuid -d -c 1 from the host:

CPUID 0000000b:00 = 00000000 00000001 00000100 00000001 | ................
CPUID 0000000b:01 = 00000002 00000004 00000201 00000001 | ................

while from propolis-server logs we just don't have a leaf B provided at all. this is because, erm, propolis-server removes it. its cpuid::Specializer is set up to clear host cpu/cache topology information from passed-through leaves (missing leaf 4 as an oversight of Intel leaves), but never gets with_cpu_topo() so in fix_cpu_topo we dutifully remove host topo leaves and do not add them back in.

this all to say: a patch for #939, which i'm also running while doing this debugging, is insufficient to fix this :)

we should set leaf B and/or 8000_001E as appropriate, which probably fixes this, but i want to understand what's up with leaf 4 as well. finally, this implies a really weird behavior that has apparently been fine on AMD: propolis-server drops leaf 8000_001E but does not unset 8000_0001.ECX[TopologyExtensions] so we're representing that the all-zero leaf is descriptive of the processor topology. i believe this is why if you look at a VM today you get an... interesting topology:

debian@debian-11:~$ likwid-topology -g

but i want to understand what's up with leaf 4 as well.

we create a VM with one vCPU and then collect all the CPUID leaves from it in query_complete. leaf 4 is fixed up given that topology, and Propolis doesn't know to re-specialize it later on. very simple bug there.

802d041 gets OmniOS to come up, so yeah a reasonable leaf 4 helps a lot. I think it'll make more sense to set with_cpu_topo based on the incoming CPUID leaves (either from an instance spec or if not in an instance spec from the current host), so that we always fix up the topo leaves we'll present to guests and never invent new leaves we weren't asked to provide.
