The Intel Restricted Access Region Handler provides a buffer allocation mechanism to RAR users. Since the intended usage model is to lock out CPU access to RAR (the CPU will not be able to access RAR memory), this driver does not access RAR memory, and merely keeps track of what areas of RAR memory are in use. It has it's own simple allocator that does not rely on existing kernel allocators (SLAB, etc) since those allocators are too tightly coupled with the paging mechanism, which isn't needed for the intended RAR use cases. An mmap() implementation is provided for debugging purposes to simplify RAR memory access from the user space. However, it will effectively be a no-op when RAR access control is enabled since the CPU will not be able to access RAR. This driver should not be confused with the rar_register driver. That driver exposes an interface to access RAR registers on the Moorestown platform. The RAR handler driver relies on the rar_register driver for low level RAR register reads and writes. This patch was generated and built against the latest linux-2.6 master branch. Signed-off-by: Ossama Othman <ossama.othman@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This option allows you to select a number of drivers that are
|
|
not of the "normal" Linux kernel quality level. These drivers
|
|
are placed here in order to get a wider audience to make use of
|
|
them. Please note that these drivers are under heavy
|
|
development, may or may not work, and may contain userspace
|
|
interfaces that most likely will be changed in the near
|
|
future.
|
|
|
|
Using any of these drivers will taint your kernel which might
|
|
affect support options from both the community, and various
|
|
commercial support organizations.
|
|
|
|
If you wish to work on these drivers, to help improve them, or
|
|
to report problems you have with them, please see the
|
|
driver_name.README file in the drivers/staging/ directory to
|
|
see what needs to be worked on, and who to contact.
|
|
|
|
If in doubt, say N here.

---help---
|
|
Are you sure you really want to build the staging drivers?
|
|
They taint your kernel, don't live up to the normal Linux
|
|
kernel quality standards, are a bit crufty around the edges,
|
|
and might go off and kick your dog when you aren't paying
|
|
attention.
|
|
|
|
Say N here to be able to select and build the Staging drivers.
|
|
This option is primarily here to prevent them from being built
|
|
when selecting 'make allyesconfg' and 'make allmodconfig' so
|
|
don't be all that put off, your dog will be just fine.
