Subject: Accessing AVX/AVX2 instruction in UEFI.
Date: Tue, 2 May 2017 13:57:01 +0000	[thread overview]
Message-ID: <MWHPR11MB1822E95D7DEB0735B40E52E0DC170@MWHPR11MB1822.namprd11.prod.outlook.com> (raw)

Hi,

Am trying to optimize an application using AVX/AVX2, but my code hangs while trying to access YMM registers.
The instruction where my code hangs is :


 vmovups ymm0, YMMWORD PTR [rax] 


I have verified the cpuid in OS and it supports AVX and AVX2 instruction. Processor i7 6th gen.
Can somebody help me out here ? Is there a way to enable YMM registers ?


Thanks And Regards
Amit Kumar
