3.3 RECOMMENDATIONS FOR SYSTEM SOFTWARE System software may disable use of Intel AMX by clearing XCR0[18:17], by clearing CR4.OSXSAVE, or by setting IA32_XFD[18]. System software should initialize AMX state (e.g., by executing TILERELEASE) when doing so because maintaining AMX state in a non-initialized state may have negative power and performance implications. In addition, software should not rely on the state of the tile data after setting
I would change this to "must not rely", otherwise looks good. Thanks! Paolo
IA32_XFD[18]; software should always reload or reinitialize the tile data after clearing IA32_XFD[18].
