24 * The structure layout of user_xstateregs, used for exporting the
25 * extended register state through ptrace and core-dump (NT_X86_XSTATE note)
26 * interfaces will be same as the memory layout of xsave used by the processor
27 * (except for the bytes 464..511, which can be used by the software) and hence
28 * the size of this structure varies depending on the features supported by the
29 * processor and OS. The size of the structure that users need to use can be
30 * obtained by doing:
31 * cpuid_count(0xd, 0, &eax, &ptrace_xstateregs_struct_size, &ecx, &edx);
32 * i.e., cpuid.(eax=0xd,ecx=0).ebx will be the size that user (debuggers, etc.)
33 * need to use.
34 *
35 * For now, only the first 8 bytes of the software usable bytes[464..471] will
36 * be used and will be set to OS enabled xstate mask (which is same as the
37 * 64bit mask returned by the xgetbv's xCR0). Users (analyzing core dump
38 * remotely, etc.) can use this mask as well as the mask saved in the
39 * xstate_hdr bytes and interpret what states the processor/OS supports
40 * and what states are in modified/initialized conditions for the
41 * particular process/thread.
42 *
43 * Also when the user modifies certain state FP/SSE/etc through the
44 * ptrace interface, they must ensure that the xsave_hdr.xstate_bv
45 * bytes[512..519] of the memory layout are updated correspondingly.
46 * i.e., for example when FP state is modified to a non-init state,
