      Documentation: prctl/seccomp_filter · 8ac270d1
      Will Drewry authored
      Documents how system call filtering using Berkeley Packet
      Filter programs works and how it may be used.
      Includes an example for x86 and a semi-generic
      example using a macro-based code generator.

      samples/rpmsg: add an rpmsg driver sample · 779b96d2
      Ohad Ben-Cohen authored
      Add an rpmsg driver sample, which demonstrates how to communicate with
      an AMP-configured remote processor over the rpmsg bus.
      
      Note how once probed, the driver can immediately start sending messages
      using the rpmsg_send() API, without having to worry about creating endpoints
      or allocating rpmsg addresses: all that work is done by the rpmsg bus,
      and the required information is already embedded in the rpmsg channel
      that the driver is probed with.
      
      In this sample, the driver simply sends a "Hello World!" message to the remote
      processor repeatedly.
