Subject: [PATCH v3 0/2] tpm: add optional max xfer size check
Date: Wed, 27 Jul 2016 20:49:55 -0700 [thread overview]
Message-ID: <1469677797-74304-1-git-send-email-apronin@chromium.org> (raw)
In-Reply-To: <1468546745-14646-1-git-send-email-apronin@chromium.org>

This patchset introduces an optional maximum transfer size that can
be specified by a tpm driver. Setting the max_xfer_size helps to catch
the cases when burstcnt is incorrectly reported by the device (e.g. >64
for spi - happened in practice) and gracefully handle such situations.
v2: removed unnecessary accessors in tpm_tis_core.h, fixed style
v3: simplified logic: simply cap the burstcnt at max_xfer_size, don't
attempt to re-request from tpm.
