+What:	/proc/<pid>/oom_adj
+When:	August 2012
+Why:	/proc/<pid>/oom_adj allows userspace to influence the oom killer's
+	badness heuristic used to determine which task to kill when the kernel
+	is out of memory.
+
+	The badness heuristic has since been rewritten since the introduction of
+	this tunable such that its meaning is deprecated.  The value was
+	implemented as a bitshift on a score generated by the badness()
+	function that did not have any precise units of measure.  With the
+	rewrite, the score is given as a proportion of available memory to the
+	task allocating pages, so using a bitshift which grows the score
+	exponentially is, thus, impossible to tune with fine granularity.
+
+	A much more powerful interface, /proc/<pid>/oom_score_adj, was
+	introduced with the oom killer rewrite that allows users to increase or
+	decrease the badness() score linearly.  This interface will replace
+	/proc/<pid>/oom_adj.
+
+	A warning will be emitted to the kernel log if an application uses this
+	deprecated interface.  After it is printed once, future warnings will be
+	suppressed until the kernel is rebooted.

-	abi_version	(0400)	Kernel's kmemtrace ABI version. (text)

-Each per-CPU file should be read according to the relay interface. That is,
-the reader should set affinity to that specific CPU and, as currently done by
-the userspace application (though there are other methods), use poll() with
-an infinite timeout before every read(). Otherwise, erroneous data may be
-read. The binary data has the following _core_ format:
-
-	Event ID	(1 byte)	Unsigned integer, one of:
-		0 - represents an allocation (KMEMTRACE_EVENT_ALLOC)
-		1 - represents a freeing of previously allocated memory
-		    (KMEMTRACE_EVENT_FREE)
-	Type ID		(1 byte)	Unsigned integer, one of:
-		0 - this is a kmalloc() / kfree()
-		1 - this is a kmem_cache_alloc() / kmem_cache_free()
-		2 - this is a __get_free_pages() et al.
-	Event size	(2 bytes)	Unsigned integer representing the
-					size of this event. Used to extend
-					kmemtrace. Discard the bytes you
-					don't know about.
-	Sequence number	(4 bytes)	Signed integer used to reorder data
-					logged on SMP machines. Wraparound
-					must be taken into account, although
-					it is unlikely.
-	Caller address	(8 bytes)	Return address to the caller.
-	Pointer to mem	(8 bytes)	Pointer to target memory area. Can be
-					NULL, but not all such calls might be

-
-In case of KMEMTRACE_EVENT_ALLOC events, the next fields follow:
-
-	Requested bytes	(8 bytes)	Total number of requested bytes,
-					unsigned, must not be zero.
-	Allocated bytes (8 bytes)	Total number of actually allocated
-					bytes, unsigned, must not be lower
-					than requested bytes.
-	Requested flags	(4 bytes)	GFP flags supplied by the caller.
-	Target CPU	(4 bytes)	Signed integer, valid for event id 1.
-					If equal to -1, target CPU is the same
-					as origin CPU, but the reverse might

-The data is made available in the same endianness the machine has.
-
-Other event ids and type ids may be defined and added. Other fields may be

+
+		Not all drivers support this attribute.  If it isn't supported,

+   (including software IOMMU).
+
+2) ARCH_DMA_MINALIGN
+
+   Architectures must ensure that kmalloc'ed buffer is
+   DMA-safe. Drivers and subsystems depend on it. If an architecture
+   isn't fully DMA-coherent (i.e. hardware doesn't ensure that data in
+   the CPU cache is identical to data in main memory),
+   ARCH_DMA_MINALIGN must be set so that the memory allocator
+   makes sure that kmalloc'ed buffer doesn't share a cache line with
+   the others. See arch/arm/include/asm/cache.h as an example.
+
+   Note that ARCH_DMA_MINALIGN is about DMA memory alignment
+   constraints. You don't need to worry about the architecture data
+   alignment constraints (e.g. the alignment constraints about 64-bit
+   objects).
+
+3) Supporting multiple types of IOMMUs
+
+   If your architecture needs to support multiple types of IOMMUs, you
+   can use include/linux/asm-generic/dma-mapping-common.h. It's a
+   library to support the DMA API with multiple types of IOMMUs. Lots
+   of architectures (x86, powerpc, sh, alpha, ia64, microblaze and
+   sparc) use it. Choose one to see how it can be used. If you need to
+   support multiple types of IOMMUs in a single system, the example of

+Get the detailed info related with the IPMI device
+--------------------------------------------------
+
+Some users need more detailed information about a device, like where
+the address came from or the raw base device for the IPMI interface.
+You can use the IPMI smi_watcher to catch the IPMI interfaces as they
+come or go, and to grab the information, you can use the function
+ipmi_get_smi_info(), which returns the following structure:
+
+struct ipmi_smi_info {

+	struct device *dev;
+	union {
+		struct {
+			void *acpi_handle;
+		} acpi_info;

+};
+
+Currently special info for only for SI_ACPI address sources is
+returned.  Others may be added as necessary.
+
+Note that the dev pointer is included in the above structure, and
+assuming ipmi_smi_get_info returns success, you must call put_device
+on the dev pointer.

+rcu_preempt section appearing only in CONFIG_TINY_PREEMPT_RCU builds.
+The last three lines of the rcu_preempt section appear only in
+CONFIG_RCU_BOOST kernel builds.  The fields are as follows:
+
+o	"qlen" is the number of RCU callbacks currently waiting either
+	for an RCU grace period or waiting to be invoked.  This is the
+	only field present for rcu_sched and rcu_bh, due to the
+	short-circuiting of grace period in those two cases.
+
+o	"gp" is the number of grace periods that have completed.
+
+o	"g197/p197/c197" displays the grace-period state, with the
+	"g" number being the number of grace periods that have started
+	(mod 256), the "p" number being the number of grace periods
+	that the CPU has responded to (also mod 256), and the "c"
+	number being the number of grace periods that have completed
+	(once again mode 256).
+
+	Why have both "gp" and "g"?  Because the data flowing into
+	"gp" is only present in a CONFIG_RCU_TRACE kernel.
+
+o	"tasks" is a set of bits.  The first bit is "T" if there are
+	currently tasks that have recently blocked within an RCU
+	read-side critical section, the second bit is "N" if any of the
+	aforementioned tasks are blocking the current RCU grace period,
+	and the third bit is "E" if any of the aforementioned tasks are
+	blocking the current expedited grace period.  Each bit is "."
+	if the corresponding condition does not hold.
+
+o	"ttb" is a single bit.  It is "B" if any of the blocked tasks
+	need to be priority boosted and "." otherwise.
+
+o	"btg" indicates whether boosting has been carried out during
+	the current grace period, with "exp" indicating that boosting
+	is in progress for an expedited grace period, "no" indicating
+	that boosting has not yet started for a normal grace period,
+	"begun" indicating that boosting has bebug for a normal grace
+	period, and "done" indicating that boosting has completed for
+	a normal grace period.
+
+o	"ntb" is the total number of tasks subjected to RCU priority boosting
+	periods since boot.
+
+o	"neb" is the number of expedited grace periods that have had
+	to resort to RCU priority boosting since boot.
+
+o	"nnb" is the number of normal grace periods that have had
+	to resort to RCU priority boosting since boot.
+
+o	"j" is the low-order 12 bits of the jiffies counter in hexadecimal.
+
+o	"bt" is the low-order 12 bits of the value that the jiffies counter
+	will have at the next time that boosting is scheduled to begin.
+
+o	In the line beginning with "normal balk", the fields are as follows:
+
+	o	"nt" is the number of times that the system balked from
+		boosting because there were no blocked tasks to boost.
+		Note that the system will balk from boosting even if the
+		grace period is overdue when the currently running task
+		is looping within an RCU read-side critical section.
+		There is no point in boosting in this case, because
+		boosting a running task won't make it run any faster.
+
+	o	"gt" is the number of times that the system balked
+		from boosting because, although there were blocked tasks,
+		none of them were preventing the current grace period
+		from completing.
+
+	o	"bt" is the number of times that the system balked
+		from boosting because boosting was already in progress.
+
+	o	"b" is the number of times that the system balked from

+
+	o	"ny" is the number of times that the system balked from

+		the grace period in question.
+
+	o	"nos" is the number of times that the system balked from
+		boosting for inexplicable ("not otherwise specified")
+		reasons.  This can actually happen due to races involving
+		increments of the jiffies counter.
+
+o	In the line beginning with "exp balk", the fields are as follows:

+			APEI Error INJection
+			~~~~~~~~~~~~~~~~~~~~
+
+EINJ provides a hardware error injection mechanism
+It is very useful for debugging and testing of other APEI and RAS features.
+
+To use EINJ, make sure the following are enabled in your kernel
+configuration:
+
+CONFIG_DEBUG_FS
+CONFIG_ACPI_APEI
+CONFIG_ACPI_APEI_EINJ
+
+The user interface of EINJ is debug file system, under the
+directory apei/einj. The following files are provided.
+
+- available_error_type
+  Reading this file returns the error injection capability of the
+  platform, that is, which error types are supported. The error type
+  definition is as follow, the left field is the error type value, the
+  right field is error description.
+
+    0x00000001	Processor Correctable
+    0x00000002	Processor Uncorrectable non-fatal
+    0x00000004	Processor Uncorrectable fatal
+    0x00000008  Memory Correctable
+    0x00000010  Memory Uncorrectable non-fatal
+    0x00000020  Memory Uncorrectable fatal
+    0x00000040	PCI Express Correctable
+    0x00000080	PCI Express Uncorrectable fatal
+    0x00000100	PCI Express Uncorrectable non-fatal
+    0x00000200	Platform Correctable
+    0x00000400	Platform Uncorrectable non-fatal
+    0x00000800	Platform Uncorrectable fatal
+
+  The format of file contents are as above, except there are only the
+  available error type lines.
+
+- error_type
+  This file is used to set the error type value. The error type value
+  is defined in "available_error_type" description.
+
+- error_inject
+  Write any integer to this file to trigger the error
+  injection. Before this, please specify all necessary error
+  parameters.
+
+- param1
+  This file is used to set the first error parameter value. Effect of
+  parameter depends on error_type specified. For memory error, this is
+  physical memory address.
+
+- param2
+  This file is used to set the second error parameter value. Effect of
+  parameter depends on error_type specified. For memory error, this is
+  physical memory address mask.
+
+For more information about EINJ, please refer to ACPI specification
+version 4.0, section 17.5.

+--- What is AppArmor? ---
+
+AppArmor is MAC style security extension for the Linux kernel.  It implements
+a task centered policy, with task "profiles" being created and loaded
+from user space.  Tasks on the system that do not have a profile defined for
+them run in an unconfined state which is equivalent to standard Linux DAC
+permissions.
+
+--- How to enable/disable ---
+
+set CONFIG_SECURITY_APPARMOR=y
+
+If AppArmor should be selected as the default security module then
+   set CONFIG_DEFAULT_SECURITY="apparmor"
+   and CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1
+
+Build the kernel
+
+If AppArmor is not the default security module it can be enabled by passing
+security=apparmor on the kernel's command line.
+
+If AppArmor is the default security module it can be disabled by passing
+apparmor=0, security=XXXX (where XXX is valid security module), on the
+kernel's command line
+
+For AppArmor to enforce any restrictions beyond standard Linux DAC permissions
+policy must be loaded into the kernel from user space (see the Documentation
+and tools links).
