Given the cache values I am seeing I believe the patch needs a small change. Looking at the cache output from ld.so --list-diagnostics without the patch, i.e., the current code: x86.cpu_features.data_cache_size=3D0x8000 x86.cpu_features.shared_cache_size=3D0x1000000000 x86.cpu_features.level1_icache_size=3D0x8000 x86.cpu_features.level1_icache_linesize=3D0x40 x86.cpu_features.level1_dcache_size=3D0x8000 x86.cpu_features.level1_dcache_assoc=3D0x8 x86.cpu_features.level1_dcache_linesize=3D0x40 x86.cpu_features.level2_cache_size=3D0x100000 x86.cpu_features.level2_cache_assoc=3D0x8 x86.cpu_features.level2_cache_linesize=3D0x40 x86.cpu_features.level3_cache_size=3D0x1000000000 x86.cpu_features.level3_cache_assoc=3D0x0 x86.cpu_features.level3_cache_linesize=3D0x40 x86.cpu_features.level4_cache_size=3D0x0 x86.cpu_features.cachesize_non_temporal_divisor=3D0x4 As Florian states in #36, the L3 cache size reporting 1TB is what triggers = the bug in glibc-2.40 (or a patched 2.39). Applying the patch from https://reviews.freebsd.org/D48187 gives these cache values: x86.cpu_features.data_cache_size=3D0x80 x86.cpu_features.shared_cache_size=3D0x2 x86.cpu_features.level1_icache_size=3D0x80 x86.cpu_features.level1_icache_linesize=3D0x40 x86.cpu_features.level1_dcache_size=3D0x80 x86.cpu_features.level1_dcache_assoc=3D0x1 x86.cpu_features.level1_dcache_linesize=3D0x40 x86.cpu_features.level2_cache_size=3D0x80 x86.cpu_features.level2_cache_assoc=3D0x1 x86.cpu_features.level2_cache_linesize=3D0x40 x86.cpu_features.level3_cache_size=3D0x2 x86.cpu_features.level3_cache_assoc=3D0x1 x86.cpu_features.level3_cache_linesize=3D0x1 x86.cpu_features.level4_cache_size=3D0x0 x86.cpu_features.cachesize_non_temporal_divisor=3D0x4 While the guest apps now work, the cache sizes are too small and not realis= tic. This is due to cpuid 0x8000001D not being fully implemented. Looking at the glibc code: =20=20=20=20 https://github.com/bminor/glibc/blob/glibc-2.40/sysdeps/x86/dl-cacheinfo.h#= L309 As Florian talks about in #39, the handle_amd() function first looks at cpu= id 0x8000001D for the cache information which is not providing all of the parameters needed to compute the correct cache sizes. If 0x8000001D is not available or the returned ecx=3D=3D0, it falls back to a legacy mechanism. = But for Zen architecture will also look at the 0x8000001D eax for the NumSharingCac= he. To get this fallback to work properly I reverted one of the changes in the proposed patch from Konstantin and only used: --- a/sys/amd64/vmm/x86.c +++ b/sys/amd64/vmm/x86.c @@ -150,8 +150,6 @@ x86_emulate_cpuid(struct vcpu *vcpu, uint64_t *rax, uint64_t *rbx, * pkg_id_shift and other OSes may rely on = it. */ width =3D MIN(0xF, log2(threads * cores)); - if (width < 0x4) - width =3D 0; logical_cpus =3D MIN(0xFF, threads * cores = - 1); regs[2] =3D (width << AMDID_COREID_SIZE_SHI= FT) | logical_cpus; } @@ -256,7 +254,7 @@ x86_emulate_cpuid(struct vcpu *vcpu, uint64_t *rax, uint64_t *rbx, func =3D 3; /* unified cache */ break; default: - logical_cpus =3D 0; + logical_cpus =3D sockets * threads * cores; level =3D 0; func =3D 0; break; The reverted change will keep 0x8000001D ecx=3D=3D0 to prevent 0x8000001D u= se in handle_amd() while still setting a better value for NumSharingCache for use= in the legacy code path. The reported cache sizes with this change shows: x86.cpu_features.data_cache_size=3D0x8000 x86.cpu_features.shared_cache_size=3D0x2000000 x86.cpu_features.level1_icache_size=3D0x8000 x86.cpu_features.level1_icache_linesize=3D0x40 x86.cpu_features.level1_dcache_size=3D0x8000 x86.cpu_features.level1_dcache_assoc=3D0x8 x86.cpu_features.level1_dcache_linesize=3D0x40 x86.cpu_features.level2_cache_size=3D0x100000 x86.cpu_features.level2_cache_assoc=3D0x8 x86.cpu_features.level2_cache_linesize=3D0x40 x86.cpu_features.level3_cache_size=3D0x2000000 x86.cpu_features.level3_cache_assoc=3D0x0 x86.cpu_features.level3_cache_linesize=3D0x40 x86.cpu_features.level4_cache_size=3D0x0 x86.cpu_features.cachesize_non_temporal_divisor=3D0x4 These values look more reasonable and fixes the guest issues on my system. Would like see if this matches what other people are seeing for cache sizes with this patch and if it resolves any outstanding issues. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Wed Mar 5 00:47:15 2025 X-Original-To: virtualization@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Z6v5h04S3z5p46L for ;

Glibc does not believe that there are fully associative L3 caches, ignoring the leaf and falling back to legacy way of reading cache params. - Do not report 4095 logical CPUs per L3 cache, report the true total number of emulated CPUs. The insanely large value tricked some version of glibc to overflow 32bit calculation of the L3 cache size, as reported in the PR. Also, for leaf 0x8000_0008, do not clip ApicIdSize to zero if less than 4. This effectively falls back to legacy.
