Subject: [Buildroot] [PATCH v3] tpm2-tools: drop dependency on tpm2-abrmd
Date: Mon, 28 Jan 2019 22:11:24 +0100	[thread overview]

Peter, All,

On 2019-01-25 16:03 +0100, Peter Korsgaard spake thusly:
> tpm2-tools is commonly used with the resource manager, tpm2-abrmd - But it
> CAN be used without, E.G. by setting the TPM2TOOLS_TCTI_NAME environment
> variable to communicate directly with the kernel driver:
> 
> export TPM2TOOLS_TCTI_NAME=device
> 
> Either directly with the TPM device (/dev/tpmN) or through the in-kernel
> resource manager provided by Linux kernel since 4.12 (/dev/tpmrmN)
> 
> For some use cases (E.G. initramfs) it makes sense to use tpm2-tools
> without abrmd, so remove the tpm2-abrmd select, and instead a note in the
> help text that it may be needed.
