Subject: [PATCH 0/3] PSP TEE driver update and bug fixes
Date: Tue, 9 Mar 2021 13:41:10 +0530 [thread overview]
Message-ID: <cover.1615276206.git.Rijo-john.Thomas@amd.com> (raw)
The first patch helps to improve the response time by reducing the
polling time of the tee command status variable.
Second patch is a bug fix to handle multi-threaded use-case.
During testing, race condition was seen due to missing synchronisation
in writes to the TEE ring buffer. This patch helps to resolve that.
Third patch is to update the copyright year for the tee driver files.
Rijo Thomas (3):
crypto: ccp - reduce tee command status polling interval from 5ms to
1ms
crypto: ccp - fix command queuing to TEE ring buffer
crypto: ccp - update copyright year for tee
