+
+RapidIO device-specific drivers follow Linux Kernel Driver Model and are
+intended to support specific RapidIO devices attached to the RapidIO network.
+
+2.6 Subsystem Interfaces
+
+RapidIO interconnect specification defines features that may be used to provide
+one or more common service layers for all participating RapidIO devices. These

+device-specific drivers. Example of such service provider is the RIONET driver
+which implements Ethernet-over-RapidIO interface. Because only one driver can be
+registered for a device, all common RapidIO services have to be registered as
+subsystem interfaces. This allows to have multiple common services attached to
+the same device without blocking attachment of a device-specific driver.

 In order to initialize the RapidIO subsystem, a platform must initialize and
 register at least one master port within the RapidIO network. To register mport

+

+  "rapidio.hdid=" with a list of destination ID assignments in order of mport
+  device registration. For example, in a system with two RapidIO controllers
+  the command line parameter "rapidio.hdid=-1,7" will result in assignment of
+  the host destination ID=7 to the second RapidIO controller, while the first
+  one will be assigned destination ID=-1.
+
+  (b) If the RapidIO subsystem core is built as a loadable module, in addition
+  to the method shown above, the host destination ID(s) can be specified using
+  traditional methods of passing module parameter "hdid=" during its loading:
+  - from command line: "modprobe rapidio hdid=-1,7", or
+  - from modprobe configuration file using configuration command "options",
+    like in this example: "options rapidio hdid=-1,7". An example of modprobe

+

+  (i) if "hdid=" parameter is omitted all available mport will be assigned
+  destination ID = -1;
+  (ii) the "hdid=" parameter in systems with multiple mports can have
+  destination ID assignments omitted from the end of list (default = -1).
+
+If the host device ID for a specific master port is set to -1, the discovery
+process will be performed for it.
 
 The enumeration and discovery routines use RapidIO maintenance transactions
 to access the configuration space of devices.
 
+NOTE: If RapidIO switch-specific device drivers are built as loadable modules
+they must be loaded before enumeration/discovery process starts.
+This requirement is cased by the fact that enumeration/discovery methods invoke

+  The soft-dirty is a bit on a PTE which helps to track which pages a task
+writes to. In order to do this tracking one should
+
+  1. Clear soft-dirty bits from the task's PTEs.
+
+     This is done by writing "4" into the /proc/PID/clear_refs file of the
+     task in question.
+
+  2. Wait some time.
+
+  3. Read soft-dirty bits from the PTEs.
+
+     This is done by reading from the /proc/PID/pagemap. The bit 55 of the
+     64-bit qword is the soft-dirty one. If set, the respective PTE was
+     written to since step 1.
+
+
+  Internally, to do this tracking, the writable bit is cleared from PTEs
+when the soft-dirty bit is cleared. So, after this, when the task tries to
+modify a page at some virtual address the #PF occurs and the kernel sets
+the soft-dirty bit on the respective PTE.
+
+  Note, that although all the task's address space is marked as r/o after the
+soft-dirty bits clear, the #PF-s that occur after that are processed fast.
+This is so, since the pages are still mapped to physical memory, and thus all
+the kernel does is finds this fact out and puts both writable and soft-dirty
+bits on the PTE.
+
+
+  This feature is actively used by the checkpoint-restore project. You
+can find more details about it on http://criu.org
