config MRST_RAR_HANDLER
tristate "RAR handler driver for Intel Moorestown platform"
depends on RAR_REGISTER
---help---
This driver provides a memory management interface to
restricted access regions (RAR) available on the Intel
Moorestown platform.
Once locked down, restricted access regions are only
accessible by specific hardware on the platform. The x86
CPU is typically not one of those platforms. As such this
driver does not access RAR, and only provides a buffer
allocation/bookkeeping mechanism.
If unsure, say N.

RAR Handler (memrar) Driver TODO Items
======================================
Maintainer: Eugene Epshteyn <eugene.epshteyn@intel.com>
memrar.h
--------
1. This header exposes the driver's user space and kernel space
interfaces. It should be moved to <linux/rar/memrar.h>, or
something along those lines, when this memrar driver is moved out
of `staging'.
a. It would be ideal if staging/rar_register/rar_register.h was
moved to the same directory.
memrar_allocator.[ch]
---------------------
1. Address potential fragmentation issues with the memrar_allocator.
2. Hide struct memrar_allocator details/fields. They need not be
exposed to the user.
a. Forward declare struct memrar_allocator.
b. Move all three struct definitions to `memrar_allocator.c'
source file.
c. Add a memrar_allocator_largest_free_area() function, or
something like that to get access to the value of the struct
memrar_allocator "largest_free_area" field. This allows the
struct memrar_allocator fields to be completely hidden from
the user. The memrar_handler code really only needs this for
statistic gathering on-demand.
d. Do the same for the "capacity" field as the
"largest_free_area" field.
3. Move memrar_allocator.* to kernel `lib' directory since it is HW
neutral.
a. Alternatively, use lib/genalloc.c instead.
b. A kernel port of Doug Lea's malloc() implementation may also
be an option.
memrar_handler.c
----------------
1. Split user space interface (ioctl code) from core/kernel code,
e.g.:
memrar_handler.c -> memrar_core.c, memrar_user.c

What: /dev/memrar
Date: March 2010
KernelVersion: 2.6.34
Contact: Eugene Epshteyn <eugene.epshteyn@intel.com>
Description: The Intel Moorestown Restricted Access Region (RAR)
Handler driver exposes an ioctl() based interface that
allows a user to reserve and release blocks of RAR
memory.
Note: A sysfs based one was not appropriate for the
RAR handler's usage model.
=========================================================
ioctl() Requests
=========================================================
RAR_HANDLER_RESERVE
-------------------
Description: Reserve RAR block.
Type: struct RAR_block_info
Direction: in/out
Errors: EINVAL (invalid RAR type or size)
ENOMEM (not enough RAR memory)
RAR_HANDLER_STAT
----------------
Description: Get RAR statistics.
Type: struct RAR_stat
Direction: in/out
Errors: EINVAL (invalid RAR type)
RAR_HANDLER_RELEASE
-------------------
Description: Release previously reserved RAR block.
Type: 32 bit unsigned integer
(e.g. uint32_t), i.e the RAR "handle".
Direction: in
Errors: EINVAL (invalid RAR handle)
=========================================================
ioctl() Request Parameter Types
=========================================================
The structures referred to above are defined as
follows:
/**
* struct RAR_block_info - user space struct that
* describes RAR buffer
* @type: Type of RAR memory (e.g.,
* RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
* @size: Requested size of a block in bytes to
* be reserved in RAR. [in]
* @handle: Handle that can be used to refer to
* reserved block. [out]
*
* This is the basic structure exposed to the user
* space that describes a given RAR buffer. It used
* as the parameter for the RAR_HANDLER_RESERVE ioctl.
* The buffer's underlying bus address is not exposed
* to the user. User space code refers to the buffer
* entirely by "handle".
*/
struct RAR_block_info {
__u32 type;
__u32 size;
__u32 handle;
};
/**
* struct RAR_stat - RAR statistics structure
* @type: Type of RAR memory (e.g.,
* RAR_TYPE_VIDEO or
* RAR_TYPE_AUDIO) [in]
* @capacity: Total size of RAR memory
* region. [out]
* @largest_block_size: Size of the largest reservable
* block. [out]
*
* This structure is used for RAR_HANDLER_STAT ioctl.
*/
struct RAR_stat {
__u32 type;
__u32 capacity;
__u32 largest_block_size;
};
Lastly, the RAR_HANDLER_RELEASE ioctl expects a
"handle" to the RAR block of memory. It is a 32 bit
unsigned integer.
