+Description:
+ The /sys/devices/ directory contains a sub-directory for each
+ System-on-Chip (SoC) device on a running platform. Information
+ regarding each SoC can be obtained by reading sysfs files. This
+ functionality is only available if implemented by the platform.
+
+ The directory created for each SoC will also house information
+ about devices which are commonly contained in /sys/devices/platform.
+ It has been agreed that if an SoC device exists, its supported
+ devices would be better suited to appear as children of that SoC.

+Embedded Memory Controller
+
+Properties:
+- name : Should be emc
+- #address-cells : Should be 1
+- #size-cells : Should be 0
+- compatible : Should contain "nvidia,tegra20-emc".
+- reg : Offset and length of the register set for the device
+- nvidia,use-ram-code : If present, the sub-nodes will be addressed
+ and chosen using the ramcode board selector. If omitted, only one
+ set of tables can be present and said tables will be used
+ irrespective of ram-code configuration.
+
+Child device nodes describe the memory settings for different configurations and clock rates.
+
+Example:
+
+ emc@7000f400 {
+ #address-cells = < 1 >;
+ #size-cells = < 0 >;
+ compatible = "nvidia,tegra20-emc";
+ reg = <0x7000f4000 0x200>;
+ }
+
+
+Embedded Memory Controller ram-code table
+
+If the emc node has the nvidia,use-ram-code property present, then the
+next level of nodes below the emc table are used to specify which settings
+apply for which ram-code settings.
+
+If the emc node lacks the nvidia,use-ram-code property, this level is omitted
+and the tables are stored directly under the emc node (see below).
+
+Properties:
+
+- name : Should be emc-tables
+- nvidia,ram-code : the binary representation of the ram-code board strappings
+ for which this node (and children) are valid.
+
+
+
+Embedded Memory Controller configuration table
+
+This is a table containing the EMC register settings for the various
+operating speeds of the memory controller. They are always located as
+subnodes of the emc controller node.
+
+There are two ways of specifying which tables to use:
+
+* The simplest is if there is just one set of tables in the device tree,
+ and they will always be used (based on which frequency is used).
+ This is the preferred method, especially when firmware can fill in
+ this information based on the specific system information and just
+ pass it on to the kernel.
+
+* The slightly more complex one is when more than one memory configuration
+ might exist on the system. The Tegra20 platform handles this during
+ early boot by selecting one out of possible 4 memory settings based
+ on a 2-pin "ram code" bootstrap setting on the board. The values of
+ these strappings can be read through a register in the SoC, and thus
+ used to select which tables to use.
+
+Properties:
+- name : Should be emc-table
+- compatible : Should contain "nvidia,tegra20-emc-table".
+- reg : either an opaque enumerator to tell different tables apart, or
+ the valid frequency for which the table should be used (in kHz).
+- clock-frequency : the clock frequency for the EMC at which this
+ table should be used (in kHz).
+- nvidia,emc-registers : a 46 word array of EMC registers to be programmed
+ for operation at the 'clock-frequency' setting.
+ The order and contents of the registers are:
+ RC, RFC, RAS, RP, R2W, W2R, R2P, W2P, RD_RCD, WR_RCD, RRD, REXT,
+ WDV, QUSE, QRST, QSAFE, RDV, REFRESH, BURST_REFRESH_NUM, PDEX2WR,
+ PDEX2RD, PCHG2PDEN, ACT2PDEN, AR2PDEN, RW2PDEN, TXSR, TCKE, TFAW,

+NVIDIA Tegra Power Management Controller (PMC)
+
+Properties:
+- name : Should be pmc
+- compatible : Should contain "nvidia,tegra<chip>-pmc".
+- reg : Offset and length of the register set for the device
+- nvidia,invert-interrupt : If present, inverts the PMU interrupt signal.
+ The PMU is an external Power Management Unit, whose interrupt output
+ signal is fed into the PMC. This signal is optionally inverted, and then
+ fed into the ARM GIC. The PMC is not involved in the detection or
+ handling of this interrupt signal, merely its inversion.
+
+Example:
+

Dynamic debug has even more useful features:
* Simple query language allows turning on and off debugging statements by
- matching any combination of:
+ matching any combination of 0 or 1 of:
- source filename
- function name
==========================
At the lexical level, a command comprises a sequence of words separated
-by whitespace characters. Note that newlines are treated as word
-separators and do *not* end a command or allow multiple commands to
-be done together. So these are all equivalent:
+by spaces or tabs. So these are all equivalent:
nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
<debugfs>/dynamic_debug/control
nullarbor:~ # echo -c ' file svcsock.c line 1603 +p ' >
<debugfs>/dynamic_debug/control
-nullarbor:~ # echo -c 'file svcsock.c\nline 1603 +p' >
- <debugfs>/dynamic_debug/control
nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
<debugfs>/dynamic_debug/control
-Commands are bounded by a write() system call. If you want to do
-multiple commands you need to do a separate "echo" for each, like:
+Command submissions are bounded by a write() system call.
+Multiple commands can be written together, separated by ';' or '\n'.
-nullarbor:~ # echo 'file svcsock.c line 1603 +p' > /proc/dprintk ;\
-> echo 'file svcsock.c line 1563 +p' > /proc/dprintk
+ ~# echo "func pnpacpi_get_resources +p; func pnp_assign_mem +p" \
+ > <debugfs>/dynamic_debug/control
-or even like:
+If your query set is big, you can batch them too:
-nullarbor:~ # (
-> echo 'file svcsock.c line 1603 +p' ;\
-> echo 'file svcsock.c line 1563 +p' ;\
-> ) > /proc/dprintk
+ ~# cat query-batch-file > <debugfs>/dynamic_debug/control
At the syntactical level, a command comprises a sequence of match
specifications, followed by a flags change specification.

- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- * Index Key Name
- * 0 FullyQualifiedDomainName
- * 1 IntegrationServicesVersion
- * 2 NetworkAddressIPv4
- * 3 NetworkAddressIPv6
- * 4 OSBuildNumber
- * 5 OSName
- * 6 OSMajorVersion
- * 7 OSMinorVersion
- * 8 OSVersion
- * 9 ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
- *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
- *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
- *
- *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ * Index Key Name
+ * 0 FullyQualifiedDomainName
+ * 1 IntegrationServicesVersion
+ * 2 NetworkAddressIPv4
+ * 3 NetworkAddressIPv6
+ * 4 OSBuildNumber
+ * 5 OSName
+ * 6 OSMajorVersion
+ * 7 OSMinorVersion
+ * 8 OSVersion
+ * 9 ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.
