proc: use CPUID to determine maximum size of XSAVE area (#2256) the maximum size of the Xsave area was previously hardcoded but the CPUID instruction can be used to determine its maximum size. 2020-12-14 17:39:01 +00:00

proc: use CPUID to determine ZMM_Hi256 region offset (#3831) The offset of state component i can be found via CPUID.(EAX=0DH,ECX=i):EBX. The ZMM_Hi256 is state component 6, so we use CPUID to enumerate the offset instead of hardcoding. For core dumps, we guess the ZMM_Hi256 offset based on xcr0 and the length of xsave region. The logic comes from binutils-gdb. Fixes #3827. 2024-10-21 16:16:57 +00:00
