[Qemu-devel] [PATCH v2 0/5] tpm: Match frontend and backend buffer sizes

From: Stefan Berger
Subject: [Qemu-devel] [PATCH v2 0/5] tpm: Match frontend and backend buffer sizes (not 2.11)
Date: Wed, 8 Nov 2017 14:01:54 -0500

This patch series does away with the hard coded buffer size in the TIS
frontend and instead retrieves the buffer size from the device that's
being used. So it gets it from the host device or the external emulator.
In case the frontend (CRB) cannot support the backend's current buffer size
(typically 4k) it can adjust the buffer size the emulator is working with
so that we will not run into the problem that the backend produces packets
that the frontend cannot deliver to due mismatching buffer sizes.


  - followed Marc-André's suggestions

Stefan Berger (5):
  tpm: Move getting TPM buffer size to backends
  tpm: pull tpm_util_request() out of tpm_util_test()
  tpm: tpm_passthrough: Read the buffer size from the host device
  tpm: tpm_emulator: get and set buffer size of device
  tpm: tpm_passthrough: Fail startup if FE buffer size < BE buffer size
