i wanted to read PCRs through INT 1A in GRUB.
I tried to understand the function update_pcr available in trusted
GRUB's boot.c but i could not understand completely.
I request a help to read the PCR values from GRUB using INT 1A, command BB02.
especially with the values to be updated in TCG_BUFFER_ADDRESS.
Any document/Link will also be helpful.
Thanks and Regards,
