From 4e28fa80886c71e6aaf85016b82ce981c0f12e6d Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Wed, 26 Aug 2015 10:26:19 +0200 Subject: S390: Add hwcaps value for vector facility. The HWCAP_S390_VX flag in hwcap field of auxiliary vector indicates if the vector facility is available and the kernel is aware of it. This can be tested with LD_SHOW_AUXV=1 . Currently it does not show te, because it was not incremented by commit "S/390: Add hwcap value for transactional execution.". Thus _DL_HWCAP_COUNT is incremented by two. ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_platforms): Add vector flag. * sysdeps/s390/dl-procinfo.h: Add vector capability. * sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VX): Define. --- sysdeps/s390/dl-procinfo.c | 4 ++-- sysdeps/s390/dl-procinfo.h | 3 ++- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'sysdeps/s390') diff --git a/sysdeps/s390/dl-procinfo.c b/sysdeps/s390/dl-procinfo.c index 96106f1..0f57f03 100644 --- a/sysdeps/s390/dl-procinfo.c +++ b/sysdeps/s390/dl-procinfo.c @@ -46,11 +46,11 @@ #if !defined PROCINFO_DECL && defined SHARED ._dl_s390_cap_flags #else -PROCINFO_CLASS const char _dl_s390_cap_flags[11][9] +PROCINFO_CLASS const char _dl_s390_cap_flags[12][9] #endif #ifndef PROCINFO_DECL = { - "esan3", "zarch", "stfle", "msa", "ldisp", "eimm", "dfp", "edat", "etf3eh", "highgprs", "te" + "esan3", "zarch", "stfle", "msa", "ldisp", "eimm", "dfp", "edat", "etf3eh", "highgprs", "te", "vx" } #endif #if !defined SHARED || defined PROCINFO_DECL diff --git a/sysdeps/s390/dl-procinfo.h b/sysdeps/s390/dl-procinfo.h index 0f728ab..151b891 100644 --- a/sysdeps/s390/dl-procinfo.h +++ b/sysdeps/s390/dl-procinfo.h @@ -21,7 +21,7 @@ #define _DL_PROCINFO_H 1 #include -#define _DL_HWCAP_COUNT 10 +#define _DL_HWCAP_COUNT 12 #define _DL_PLATFORMS_COUNT 5 @@ -50,6 +50,7 @@ enum HWCAP_S390_ETF3EH = 1 << 8, HWCAP_S390_HIGH_GPRS = 1 << 9, HWCAP_S390_TE = 1 << 10, + HWCAP_S390_VX = 1 << 11, }; #define HWCAP_IMPORTANT (HWCAP_S390_ZARCH | HWCAP_S390_LDISP \ -- cgit v1.1
