Two questions about IMA

[Zhao, Shirley]

Hi, all, 

This is Shirley from, I am a newer of IMA. 
I have some questions. Can you help?

According to the guide: https://sourceforge.net/p/linux-ima/wiki/Home/#linux-extended-verification-module-evm. 
1.	How to calculate the template hash in /sys/kernel/security/ima/ascii_runtime_measurements? Like below:
PCR     template-hash                           filedata-hash                           filename-hint

2.	Ubuntu 20.04 is installed on my machine, but ascii_bios_measurements canât be found under /sys/kernel/security/tpm0/. 
There is only binary_bios_measurements under tpm0/. 
So where to find the bios measure list on Ubuntu 20.04?

Thanks.
