Hello

I dont know how to begin my question... I was trying to start the
VIA PadLock ACE. I compiled my custom kernel 4.99.20 with the option
VIA_PADLOCK. I could not see difference between the GENERIC dmesg
and the new one.

My machine is a MSI Axis 700 Lite barebone. The motherboard is mini-ITX
MS-7199 with VIA C7 processor and VIA CN700 and VT8237R+ for north
and southbridge. MSI manual says "Security Feature RGN/AES/SHA-1" in
the mainboard specificatios section.

In the dmesg, I can not see evidence of AES in the cpu flags (complete
dmesg is at end of this mail)

polaris# dmesg | grep cpu0

polaris#

The CPU name must be C7, 799.99 is ok (I am using low speed)
Note the SpeedStep is incorrectly detected.

Trying to find the cause, I added a "printf" to the file
/sys/arch/x86/x86/via_padlock.c before a new compilation:

void
via_padlock_attach(void)
{
         if (!(cpu_feature_padlock & CPUID_FEAT_VACE)) {
                 printf("PadLock: MYTEST No cpu feature No CPU FEAT VACE\n");
                 return;
         }

and now, the new dmesg display my printf. I would like to investigate the
cause in the source code but it is too easy to burn the brain :)

What can I do?

Thanks in advance
