| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an implementation of para-virtualized SCM driver. This driver is the FE. The BE is QCPE running in an hypervisor. The FE driver forwards SCM calls over HAB to the BE. Change-Id: I88c269e856b0a6cc20b9ab8bf10110842d90a382 Signed-off-by: Amit Blay <ablay@codeaurora.org>

|/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have observed race condition between inquiring the remote pd state and indication call back execution. They run asynchronously so we have no control on their concurrent execution. So to achieve mutual exclusion, moving the portion of code which result in race condition to indication acknowledgment routine. Indication acknowledgment is send in separate thread context which will avoid race condition.

This region may be adjacent to other regions that also requires access control, due to that TZ will merge the two sections into one single resource group. During this Q6 will lose access to memory region causing a NOC Error. To avoid use fixed memory region for WLAN MSA0 memory.

The userspace can invoke the "read" call from multiple threads which will call "msm_rpmstats_file_read" which in turn calls "msm_rpmstats_copy_stats". This can allow the statement "pdata->read_idx++" increment "read_idx" beyond the limit ("prvdata->num_records") and call "msm_rpmstats_read_register" with this value. Also allow reading RPM stats information using sysfs nodes.
