[PATCH v2 0/5] Qualcomm remote filesystem shared memory driver

Show all headers | View 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.

Bjorn Andersson (5):
  of/platform: Generalize /reserved-memory handling
  of: reserved_mem: Accessor for acquiring reserved_mem
  dt-binding: soc: qcom: Add binding for RFSA
  soc: qcom: Remote FS memory driver
  arm64: dts: msm8916: Mark rmtfs node as qcom,rfsa compatible
