commit ee7e49e19388fd0f19ca1c4773d3efc5fa123d58 Author: Jinke Fan <[email protected]> Date: Fri May 17 11:29:11 2019 +0800 Add support for Hygon Dhyana processor -Add vendor identification -Support in get_cpu_cache Background: Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture between AMD and Haiguang Information Technology Co.,Ltd., aims at providing high performance x86 processor for China server market. Its first generation processor codename is Dhyana, which originates from AMD technology and shares most of the architecture with AMD's family 17h, but with different CPU Vendor ID("HygonGenuine")/Family series number(Family 18h). Related Hygon kernel patch can be found on: http://lkml.kernel.org/r/5ce86123a7b9dad925ac583d88d2f921040e859b.1538583282.git.pu...@hygon.cn Signed-off-by: Jinke Fan <[email protected]> Diff: --- winsup/cygwin/fhandler_proc.cc | 3 ++- winsup/cygwin/sysconf.cc | 3 ++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/winsup/cygwin/fhandler_proc.cc b/winsup/cygwin/fhandler_proc.cc index a6a0b68..c461bbc 100644 --- a/winsup/cygwin/fhandler_proc.cc +++ b/winsup/cygwin/fhandler_proc.cc @@ -706,7 +706,8 @@ format_proc_cpuinfo (void *, char *&destbuf) /* Vendor identification. */ bool is_amd = false, is_intel = false; - if (!strcmp ((char*)vendor_id, "AuthenticAMD")) + if (!strcmp ((char*)vendor_id, "AuthenticAMD") + || !strcmp((char*)vendor_id, "HygonGenuine")) is_amd = true; else if (!strcmp ((char*)vendor_id, "GenuineIntel")) is_intel = true; diff --git a/winsup/cygwin/sysconf.cc b/winsup/cygwin/sysconf.cc index 216e514..3440c09 100644 --- a/winsup/cygwin/sysconf.cc +++ b/winsup/cygwin/sysconf.cc @@ -486,7 +486,8 @@ get_cpu_cache (int in) vendor_id[3] = 0; if (!strcmp ((char*) vendor_id, "GenuineIntel")) return get_cpu_cache_intel (in, maxf & 0xffff); - else if (!strcmp ((char*)vendor_id, "AuthenticAMD")) + else if (!strcmp ((char*)vendor_id, "AuthenticAMD") + || !strcmp((char*)vendor_id, "HygonGenuine")) { uint32_t maxe = 0, unused; cpuid (&maxe, &unused, &unused, &unused, 0x80000000);
