Subject: [RESEND: PATCH v4 0/4] Add memory ownership switch support and enable mss rproc on msm8996
Date: Tue, 16 May 2017 23:31:58 +0530 [thread overview]
Message-ID: <1494957722-13264-1-git-send-email-akdwived@codeaurora.org> (raw)
This patch does following
1- Adds new scm call which helps in stage two translation of a memory region
so that memory ownership sharing and switching can be achieved on armv8 and later.
2- Enable mss remoteproc on msm8996
Major changes since last patch:
1- Refactored SCM API
2- Changed SCM API Signature
3- Added cpu_to_le32() as and where required
4- Elaborated documentation of new API added
5- Refactored MSS rproc code which make the scm api call
6- Refactored mss rproc code to first load all segments and then transfer ownership of
memory region to MSS for authentication and boot etc.
7- Other Minor changes
8- kbuild robot gave error so added dummy definition of __qcom_scm_assign_mem() in qcom_scm-32.c as well
