From 3e9099b4f6666cd05b62d2829f65161daddb151b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 23 Jul 2009 13:42:46 -0700 Subject: [PATCH] Add more cache descriptors for L3 caches on x86 and x86-64. The most recent AP 485 describes a few more cache descriptors for L3 caches with 24-way associativity. --- ChangeLog | 4 ++++ sysdeps/unix/sysv/linux/i386/sysconf.c | 3 +++ sysdeps/x86_64/cacheinfo.c | 3 +++ 3 files changed, 10 insertions(+) diff --git a/ChangeLog b/ChangeLog index 1498e4a3c09..29e4468ce41 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,9 @@ 2009-07-23 Ulrich Drepper + * sysdeps/unix/sysv/linux/i386/sysconf.c (intel_02_known): Add more + cache descriptors. + * sysdeps/x86_64/cacheinfo.c (intel_02_known): Likewise. + * sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): Reset SSSE3 bit for Atoms. * sysdeps/x86_64/multiarch/strcpy.S: New need to perform Atom test diff --git a/sysdeps/unix/sysv/linux/i386/sysconf.c b/sysdeps/unix/sysv/linux/i386/sysconf.c index efe1a639cd2..ff3cf9f7c76 100644 --- a/sysdeps/unix/sysv/linux/i386/sysconf.c +++ b/sysdeps/unix/sysv/linux/i386/sysconf.c @@ -138,6 +138,9 @@ static const struct intel_02_cache_info { 0xe3, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 2097152 }, { 0xe3, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 4194304 }, { 0xe4, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 8388608 }, + { 0xea, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 12582912 }, + { 0xeb, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 18874368 }, + { 0xec, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 25165824 }, }; #define nintel_02_known (sizeof (intel_02_known) / sizeof (intel_02_known[0])) diff --git a/sysdeps/x86_64/cacheinfo.c b/sysdeps/x86_64/cacheinfo.c index 362687c1815..07939099b93 100644 --- a/sysdeps/x86_64/cacheinfo.c +++ b/sysdeps/x86_64/cacheinfo.c @@ -100,6 +100,9 @@ static const struct intel_02_cache_info { 0xe3, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 2097152 }, { 0xe3, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 4194304 }, { 0xe4, 16, 64, M(_SC_LEVEL3_CACHE_SIZE), 8388608 }, + { 0xea, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 12582912 }, + { 0xeb, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 18874368 }, + { 0xec, 24, 64, M(_SC_LEVEL3_CACHE_SIZE), 25165824 }, }; #define nintel_02_known (sizeof (intel_02_known) / sizeof (intel_02_known [0])) -- 2.47.2
