Subject: [PATCH v2 0/5] Qualcomm remote filesystem shared memory driver
Date: Wed, 2 Aug 2017 19:57:49 -0700 [thread overview]
Message-ID: <20170803025754.19101-1-bjorn.andersson@linaro.org> (raw)
Some remote processors (in particular the modem) found in Qualcomm platforms
stores configuration parameters and other data in a file system. As the remotes
does not have direct storage access it needs to relay block accesses through a
service running on the application CPU.
The memory is described in DeviceTree by a new reserved-memory compatible and
the implementation provides the user space service a read/write interface to
this chunk of memory.
