Dear Experts,
Now I find in TcgPhysicalPresenceLibProcessRequest() , it will set default flags value in tpm physical present variable as FLAG_NO_PPI_PROVISION.
This will cause before running some TPM commands requested from asl or setup, it may not pop up dialog window during post.
I think this may cause user confusion that BIOS stealthily changes TPM status without user confirm as old operation mode before is not like this.
Should we change that default value as 0?
Thanks.
