Subject: [PATCH] misc: fastrpc: Update number of max fastrpc sessions
Date: Mon, 20 Sep 2021 13:04:34 +0530 [thread overview]
Message-ID: <1632123274-32054-1-git-send-email-jeyr@codeaurora.org> (raw)
For latest chipsets, upto 13 fastrpc sessions can be
supported. This includes 12 compute sessions and 1 cpz
session. Not updating this might result to out of bounds
memory access issues if more than 9 context bank nodes
are added to the DT file.
