With the dump-capture kernel, you can access the memory image, or "old

- Through a /dev/oldmem device interface. A capture utility can read the
device file and write out the memory in raw format. This is a raw dump
of memory. Analysis and capture tools must be intelligent enough to
determine where to look for the right information.
- Through /proc/vmcore. This exports the dump as an ELF-format file that
you can write out using file copy commands such as cp or scp. Further,
you can use analysis tools such as the GNU Debugger (GDB) and the Crash
tool to debug the dump file. This method ensures that the dump pages are

2.5 Device Drivers
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
common services may act separately from device-specific drivers or be used by
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.
3. Subsystem Initialization
---------------------------
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
within the subsystem controller driver initialization code calls function
within the subsystem controller driver's initialization code calls function
rio_register_mport() for each available master port.
RapidIO subsystem uses subsys_initcall() or device_initcall() to perform
controller initialization (depending on controller device type).
After all active master ports are registered with a RapidIO subsystem,
an enumeration and/or discovery routine may be called automatically or
by user-space command.
RapidIO subsystem can be configured to be built as a statically linked or
modular component of the kernel (see details below).
4. Enumeration and Discovery

Enumeration is performed by a master port if it is configured as a host port by
assigning a host device ID greater than or equal to zero. A host device ID is
assigned to a master port through the kernel command line parameter "riohdid=",
or can be configured in a platform-specific manner. If the host device ID for
a specific master port is set to -1, the discovery process will be performed
for it.
assigning a host destination ID greater than or equal to zero. The host
destination ID can be assigned to a master port using various methods depending
on RapidIO subsystem build configuration:
(a) For a statically linked RapidIO subsystem core use command line parameter
"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
configuration file is provided in the section below.
NOTES:
(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
vendor-specific callbacks on early stages.

4.6 Using Loadable RapidIO Switch Drivers
-----------------------------------------
In the case when RapidIO switch drivers are built as loadable modules a user
must ensure that they are loaded before the enumeration/discovery starts.
This process can be automated by specifying pre- or post- dependencies in the
RapidIO-specific modprobe configuration file as shown in the example below.
File /etc/modprobe.d/rapidio.conf:
----------------------------------
# Configure RapidIO subsystem modules
# Set enumerator host destination ID (overrides kernel command line option)
options rapidio hdid=-1,2
# Load RapidIO switch drivers immediately after rapidio core module was loaded
softdep rapidio post: idt_gen2 idtcps tsi57x
# OR :
# Load RapidIO switch drivers just before rio-scan enumerator module is loaded
softdep rio-scan pre: idt_gen2 idtcps tsi57x
--------------------------
NOTE: In the example above, one of "softdep" commands must be removed or
commented out to keep required module loading sequence.

SOFT-DIRTY PTEs
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
