+Description:
+		Perform SMBIOS calls on supported Dell machines.
+		through the Dell ACPI-WMI interface.
+
+		IOCTL's and buffer formats are defined in:
+		<uapi/linux/wmi.h>
+
+		1) To perform an SMBIOS call from userspace, you'll need to
+		first determine the minimum size of the calling interface
+		buffer for your machine.
+		Platforms that contain larger buffers can return larger
+		objects from the system firmware.
+		Commonly this size is either 4k or 32k.
+
+		To determine the size of the buffer read() a u64 dword from
+		the WMI character device /dev/wmi/dell-smbios.
+
+		2) After you've determined the minimum size of the calling
+		interface buffer, you can allocate a structure that represents
+		the structure documented above.
+
+		3) In the 'length' object store the size of the buffer you
+		determined above and allocated.
+
+		4) In this buffer object, prepare as necessary for the SMBIOS
+		call you're interested in.  Typically SMBIOS buffers have
+		"class", "select", and "input" defined to values that coincide
+		with the data you are interested in.
+		Documenting class/select/input values is outside of the scope
+		of this documentation. Check with the libsmbios project for
+		further documentation on these values.
+
+		6) Run the call by using ioctl() as described in the header.
+
+		7) The output will be returned in the buffer object.
+
+		8) Be sure to free up your allocated object.

@@ -7,17 +7,37 @@ Description:
 		HMAC-sha1 value across the extended attributes, storing the
 		value as the extended attribute 'security.evm'.
 
-		EVM depends on the Kernel Key Retention System to provide it
-		with a trusted/encrypted key for the HMAC-sha1 operation.
-		The key is loaded onto the root's keyring using keyctl.  Until
-		EVM receives notification that the key has been successfully
-		loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
-		can not create or validate the 'security.evm' xattr, but
-		returns INTEGRITY_UNKNOWN.  Loading the key and signaling EVM
-		should be done as early as possible.  Normally this is done
-		in the initramfs, which has already been measured as part
-		of the trusted boot.  For more information on creating and
-		loading existing trusted/encrypted keys, refer to:
-		Documentation/keys-trusted-encrypted.txt.  (A sample dracut
-		patch, which loads the trusted/encrypted key and enables
-		EVM, is available from http://linux-ima.sourceforge.net/#EVM.)
+		EVM supports two classes of security.evm. The first is
+		an HMAC-sha1 generated locally with a
+		trusted/encrypted key stored in the Kernel Key
+		Retention System. The second is a digital signature
+		generated either locally or remotely using an
+		asymmetric key. These keys are loaded onto root's
+		keyring using keyctl, and EVM is then enabled by
+		echoing a value to <securityfs>/evm:
+
+		1: enable HMAC validation and creation
+		2: enable digital signature validation
+		3: enable HMAC and digital signature validation and HMAC
+		   creation
+
+		Further writes will be blocked if HMAC support is enabled or
+		if bit 32 is set:
+
+		echo 0x80000002 ><securityfs>/evm
+
+		will enable digital signature validation and block
+		further writes to <securityfs>/evm.
+
+		Until this is done, EVM can not create or validate the
+		'security.evm' xattr, but returns INTEGRITY_UNKNOWN.
+		Loading keys and signaling EVM should be done as early

Documentation/acpi/lpit.txt

+To enumerate platform Low Power Idle states, Intel platforms are using
+“Low Power Idle Table” (LPIT). More details about this table can be
+downloaded from:
+http://www.uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf
+
+Residencies for each low power state can be read via FFH
+(Function fixed hardware) or a memory mapped interface.
+
+On platforms supporting S0ix sleep states, there can be two types of
+residencies:
+- CPU PKG C10 (Read via FFH interface)
+- Platform Controller Hub (PCH) SLP_S0 (Read via memory mapped interface)
+
+The following attributes are added dynamically to the cpuidle
+sysfs attribute group:
+	/sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
+	/sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
+
+The "low_power_idle_cpu_residency_us" attribute shows time spent
+by the CPU package in PKG C10
+
+The "low_power_idle_system_residency_us" attribute shows SLP_S0
+residency, or system time spent with the SLP_S0# signal asserted.
+This is the lowest possible system power state, achieved only when CPU is in
+PKG C10 and all functional blocks in PCH are in a low power state.
