    185  * XCR0_FPU: Known FPU bits, only these get enabled.  The save area is
    186  * sized for all the fields below.
    187  *
    188  * Any bits added to this will expand the extended CPU state that we
    189  * may have to save and restore with XSAVE for userland processes,
    190  * either in the kernel when preempting threads, or on the user's stack
    191  * when delivering a signal.
    192  *
    193  * The kernel can dyanmically allocate larger sizes (on amd64, anyway,
    194  * though not currently on i386 or Xen PV).  But if the XSAVE area is
    195  * expanded so much that it and mcontext_t exceed MINSIGSTKSZ
    196  * (currently 8192), a userland ABI change and compatibility layer is
    197  * required to accommodate that, because existing programs may use
    198  * sigaltstack(2) with stacks sized for the old MINSIGSTKSZ.
    199  *
    200  * The current stack requirement is 3160 bytes of space plus up to
    201  * 63+15+8=86 bytes of padding for alignment (could be reduced by
    202  * around 512 bytes by having mcontext_t overlap with the XSAVE area a
    203  * little in machdep.c cpu_getmcontext_xsave, but we don't do that
    204  * right now):
    205  *
    206  * - mcontext_t (728 bytes: general registers and 512-byte FXSAVE area)
    207  * - XSAVE header (576 bytes: 512 bytes of FXSAVE, 64 bytes of metadata)
    208  * - AVX state: ymm0..ymm15 high 128-bit halves (256 bytes)
    209  * - AVX-512 state:
    210  *   . k0..k7 opmask registers (64 bytes)
    211  *   . zmm0..zmm15 high 256-bit halves (512 bytes)
    212  *   . zmm16..zmm31 registers (1024 bytes)
    213  *
    214  * Likely future extensions that would expand the state beyond
    215  * MINSIGSTKSZ:
    216  *
    217  * - AMX (Advanced Matrix Extensions) and ACE (AI Compute Extensions)
    218  *   state:
    219  *   . [AMX/ACE] TILECFG (64 bytes)
    220  *   . [AMX/ACE] TILEDATA (8192 bytes)
    221  *   . [ACE] SCALEDATA (128 bytes)
    222  *
    223  * As a precaution against ABI breakage, x86/identcpu.c will panic at
    224  * boot if the XSAVE state size enabled in XCR0 exceeds MINSIGSTKSZ.
