https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=279901 --- Comment #71 from Koichiro Iwao <meta@FreeBSD.org> --- (In reply to Mark Peek from comment #69) With your patch, EL8 glibc no longer crashes. It looks good to me as for this issue. However, it still reports wrong L3 cache size. My processor is AMD Ryzen 7 5700G (8-core/16-threads) so it has the following cache sizes. L1: 64KiB (32KiB instruction + 32KiB data/core) L2: 4MiB (512KiB/core) L3: 16MiB https://www.techpowerup.com/cpu-specs/ryzen-7-5700g.c2472 (AlmaLinux 9 on bhyve with D48187 patch) $ ld.so --list-diagnostics | grep cache x86.cpu_features.data_cache_size=0x8000 x86.cpu_features.shared_cache_size=0x2000000 x86.cpu_features.level1_icache_size=0x8000 # 32768 -> 32KiB x86.cpu_features.level1_icache_linesize=0x40 x86.cpu_features.level1_dcache_size=0x8000 # 32768 -> 32KiB x86.cpu_features.level1_dcache_assoc=0x8 x86.cpu_features.level1_dcache_linesize=0x40 x86.cpu_features.level2_cache_size=0x80000 # 524288 -> 512KiB x86.cpu_features.level2_cache_assoc=0x8 x86.cpu_features.level2_cache_linesize=0x40 x86.cpu_features.level3_cache_size=0x2000000 # 33554432 -> 32MiB <= WRONG! x86.cpu_features.level3_cache_assoc=0x0 x86.cpu_features.level3_cache_linesize=0x40 x86.cpu_features.level4_cache_size=0x0 x86.cpu_features.cachesize_non_temporal_divisor=0x4 -- You are receiving this mail because: You are the assignee for the bug.
