Hi Mayuri,
Please find my response inline -
1)Do we need to do any changes in coreboot to support low latency kernel?
Before answering the question, I would ask you to a bit more specific to the question as to what kernel configuration you are using to make it low-latency kernel.
The most relevant kernel options if you want to recompile your kernel yourself to have a low-latency desktop are:
PREEMPT=y
and:
CONFIG_1000_HZ=y and/or CONFIG_NO_HZ=y
- Is there a way to communicate from SeaBIOS to GRUB regarding selection of any particular partition for recover?
I have run SeaBIOS with GRUB as payload over qemu-x86 and get a grub shell. After you get the grub shell, you should be able to recover any particular partition i.e. any partition with the /boot directory containing the vmlinuz and other boot image files can be booted.
Though I have done it over qemu-x86 (but that should not matter.)
3)Has anybody tested TPM (Trusted platform module for Intel SOC) with coreboot and seabios? Any help will be appreciated.
Sorry, NO.
