--- Comment #4 from Perry Yuan(AMD) (perry.y...@amd.com) --- [AMD Official Use Only - AMD Internal Distribution Only] Thanks for the confirm. AMD has released new BIOS to OEMs, however it is really depending on vendor release plan. You can submit support case to vendor to speed up the process.

Is AMD in contact with vendors to push them to enable it? They make people think AMD CPUs suck in idle power draw. $ rdmsr 0xc00102b3 -a 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 $ rdmsr 0xc00102b0 -a dc912a10 dc912a10dc912a10 e2912a10 e2912a10e2912a10 e8912a10 e8912a10e8912a10 d0912a10 d0912a10d0912a10 e8912a10 e8912a10e8912a10 d6912a10 d6912a10d6912a10 c4912a10 c4912a10c4912a10 ca912a10 ca912a10ca912a10 $ rdmsr 0xc00102b1 -a 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 $ cpuid Leaf Subleaf EAX EBX ECX EDX 80000008 00000000: 00003030 00.. 111ef257 W... 0000400f .@.. 00010000 .... $ python -c "print(0x111ef257 & (0x1 << 27))" 0 -- You may reply to this email to add a comment.
