What: /dev/kmsg
|

Date: Mai 2012
|

KernelVersion: 3.5
|
||||
Contact: Kay Sievers <kay@vrfy.org>
|
||||
Description: The /dev/kmsg character device node provides userspace access
|
||||
to the kernel's printk buffer.
|
||||
|
||||
Injecting messages:
|
||||
Every write() to the opened device node places a log entry in
|
||||
the kernel's printk buffer.
|
||||
|
||||
The logged line can be prefixed with a <N> syslog prefix, which
|
||||
carries the syslog priority and facility. The single decimal
|
||||
prefix number is composed of the 3 lowest bits being the syslog
|
||||
priority and the higher bits the syslog facility number.
|
||||
|
||||
If no prefix is given, the priority number is the default kernel
|
||||
log priority and the facility number is set to LOG_USER (1). It
|
||||
is not possible to inject messages from userspace with the
|
||||
facility number LOG_KERN (0), to make sure that the origin of
|
||||
the messages can always be reliably determined.
|
||||
|
||||
Accessing the buffer:
|
||||
Every read() from the opened device node receives one record
|
||||
of the kernel's printk buffer.
|
||||
|
||||
The first read() directly following an open() always returns
|
||||
first message in the buffer; there is no kernel-internal
|
||||
persistent state; many readers can concurrently open the device
|
||||
and read from it, without affecting other readers.
|
||||
|
||||
Every read() will receive the next available record. If no more
|
||||
records are available read() will block, or if O_NONBLOCK is
|
||||
used -EAGAIN returned.
|
||||
|
||||
Messages in the record ring buffer get overwritten as whole,
|
||||
there are never partial messages received by read().
|
||||
|
||||
In case messages get overwritten in the circular buffer while
|
||||
the device is kept open, the next read() will return -EPIPE,
|
||||
and the seek position be updated to the next available record.
|
||||
Subsequent reads() will return available records again.
|
||||
|
||||
Unlike the classic syslog() interface, the 64 bit record
|
||||
sequence numbers allow to calculate the amount of lost
|
||||
messages, in case the buffer gets overwritten. And they allow
|
||||
to reconnect to the buffer and reconstruct the read position
|
||||
if needed, without limiting the interface to a single reader.
|
||||
|
||||
The device supports seek with the following parameters:
|
||||
SEEK_SET, 0
|
||||
seek to the first entry in the buffer
|
||||
SEEK_END, 0
|
||||
seek after the last entry in the buffer
|
||||
SEEK_DATA, 0
|
||||
seek after the last record available at the time
|
||||
the last SYSLOG_ACTION_CLEAR was issued.
|
||||
|
||||
The output format consists of a prefix carrying the syslog
|
||||
prefix including priority and facility, the 64 bit message
|
||||
sequence number and the monotonic timestamp in microseconds,
|
||||
and a flag field. All fields are separated by a ','.
|
||||
|
||||
Future extensions might add more comma separated values before
|
||||
the terminating ';'. Unknown fields and values should be
|
||||
gracefully ignored.
|
||||
|
||||
The human readable text string starts directly after the ';'
|
||||
and is terminated by a '\n'. Untrusted values derived from
|
||||
hardware or other facilities are printed, therefore
|
||||
all non-printable characters and '\' itself in the log message
|
||||
are escaped by "\x00" C-style hex encoding.
|
||||
|
||||
A line starting with ' ', is a continuation line, adding
|
||||
key/value pairs to the log message, which provide the machine
|
||||
readable context of the message, for reliable processing in
|
||||
userspace.
|
||||
|
||||
Example:
|
||||
7,160,424069,-;pci_root PNP0A03:00: host bridge window [io 0x0000-0x0cf7] (ignored)
|
||||

||||

6,339,5140900,-;NET: Registered protocol family 10
|
||||
30,340,5690716,-;udevd[80]: starting version 181
|
||||
|
||||
The DEVICE= key uniquely identifies devices the following way:
|
||||
b12:8 - block dev_t
|
||||
c127:3 - char dev_t
|
||||
n8 - netdev ifindex
|
||||
+sound:card0 - subsystem:devname
|
||||
|
||||
The flags field carries '-' by default. A 'c' indicates a
|
||||
fragment of a line. All following fragments are flagged with
|
||||
'+'. Note, that these hints about continuation lines are not
|
||||
neccessarily correct, and the stream could be interleaved with
|
||||
unrelated messages, but merging the lines in the output
|
||||
usually produces better human readable results. A similar
|
||||
logic is used internally when messages are printed to the
|
||||
console, /proc/kmsg or the syslog() syscall.

Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel
|
||||
Forwarder, which is a FCoE switch that can accept FCoE
|
||||
(Ethernet) packets, unpack them, and forward the embedded
|
||||
Fibre Channel frames into a FC fabric. It can also take
|
||||
outbound FC frames and pack them in Ethernet packets to
|
||||
be sent to their destination on the Ethernet segment.
|
||||
Attributes:
|
||||
|
||||
fabric_name: Identifies the fabric that the FCF services.
|
||||
|
||||
switch_name: Identifies the FCF.
|
||||

priority: The switch's priority amongst other FCFs on the same
|
||||
fabric.

|
||||
0 indicates that the swich will not be used.

vfid: The Virtual Fabric ID

fka_peroid: The FIP Keep-Alive peroid
|

fabric_state: The internal kernel state
|
||||
"Unknown" - Initialization value
|
||||
"Disconnected" - No link to the FCF/fabric
|
||||
"Connected" - Host is connected to the FCF
|
||||
"Deleted" - FCF is being removed from the system
|
||||
|
||||
dev_loss_tmo: The device loss timeout peroid for this FCF.
|
||||
|
||||
Notes: A device loss infrastructre similar to the FC Transport's
|
||||
is present in fcoe_sysfs. It is nice to have so that a
|
||||
link flapping adapter doesn't continually advance the count
|
||||
used to identify the discovered FCF. FCFs will exist in a
|
||||
"Disconnected" state until either the timer expires and the
|
||||
FCF becomes "Deleted" or the FCF is rediscovered and becomes
|
||||
"Connected."
|
||||
|
||||
|
||||
Users: The first user of this interface will be the fcoeadm application,
|
||||
which is commonly packaged in the fcoe-utils package.

Description:

Sets channel Y REFin frequency in Hz. In some clock chained
|

applications, the reference frequency used by the PLL may
|

change during runtime. This attribute allows the user to
|

adjust the reference frequency accordingly.
|

The value written has no effect until out_altvoltageY_frequency
|
||||
is updated. Consider to use out_altvoltageY_powerdown to power
|
||||
down the PLL and it's RFOut buffers during REFin changes.

If the extcon object has an optional callback "show_state"

If the default callback for showing function is used, the

In this example, the extcon device have USB_OTG and TA
|

cables attached and HDMI and EAR_JACK cables detached.
|
||||
|
||||
In order to update the state of an extcon device, enter a hex
|

state number starting with 0x.
|

echo 0xHEX > state
|
||||

This updates the whole state of the extcon dev.

mutually_exclusive contidions if they exist.
|

It is recommended to use this "global" state interface if

multiple cable states of an extcon device simultaneously.

|

Description:
|
||||
This allows the user to examine and adjust the criteria by which
|
||||
mtd returns -EUCLEAN from mtd_read() and mtd_read_oob(). If the
|
||||
maximum number of bit errors that were corrected on any single
|
||||
region comprising an ecc step (as reported by the driver) equals
|
||||
or exceeds this value, -EUCLEAN is returned. Otherwise, absent
|
||||
an error, 0 is returned. Higher layers (e.g., UBI) use this
|
||||
return code as an indication that an erase block may be
|
||||
degrading and should be scrutinized as a candidate for being
|
||||
marked as bad.
|
||||
|
||||
The initial value may be specified by the flash device driver.
|
||||
If not, then the default value is ecc_strength.
|
||||
|
||||
The introduction of this feature brings a subtle change to the
|
||||
meaning of the -EUCLEAN return code. Previously, it was
|
||||
interpreted to mean simply "one or more bit errors were
|
||||
corrected". Its new interpretation can be phrased as "a
|
||||
dangerously high number of bit errors were corrected on one or
|
||||
more regions comprising an ecc step". The precise definition of
|
||||
"dangerously high" can be adjusted by the user with
|
||||
bitflip_threshold. Users are discouraged from doing this,
|
||||
however, unless they know what they are doing and have intimate
|
||||
knowledge of the properties of their device. Broadly speaking,
|
||||
bitflip_threshold should be low enough to detect genuine erase
|
||||
block degradation, but high enough to avoid the consequences of
|
||||
a persistent return value of -EUCLEAN on devices where sticky
|
||||
bitflips occur. Note that if bitflip_threshold exceeds
|
||||
ecc_strength, -EUCLEAN is never returned by the read operations.
|
||||
Conversely, if bitflip_threshold is zero, -EUCLEAN is always
|
||||
returned, absent a hard error.
|
||||
|
||||
This is generally applicable only to NAND flash devices with ECC
|
||||
capability. It is ignored on devices lacking ECC capability;
|
||||
i.e., devices for which ecc_strength is zero.

Description: This write-only control file will zero all the statistical
|

counters for UE and CE errors on the given memory controller.
|
||||
Zeroing the counters will also reset the timer indicating how
|

long since the last counter were reset. This is useful for
|
||||
computing errors/time. Since the counters are always reset
|
||||
at driver initialization time, no module/kernel parameter
|

is available.

|
|||
consistent or non-consistent memory as it sees fit. By using this API,
|
||||
you are guaranteeing to the platform that you have all the correct and
|

necessary sync points for this memory in the driver.
|
||||
|
||||
DMA_ATTR_NO_KERNEL_MAPPING
|
||||
--------------------------
|
||||
|
||||
DMA_ATTR_NO_KERNEL_MAPPING lets the platform to avoid creating a kernel
|
||||
virtual mapping for the allocated buffer. On some architectures creating
|
||||
such mapping is non-trivial task and consumes very limited resources
|
||||
(like kernel virtual address space or dma consistent address space).
|
||||
Buffers allocated with this attribute can be only passed to user space
|
||||
by calling dma_mmap_attrs(). By using this API, you are guaranteeing
|
||||
that you won't dereference the pointer returned by dma_alloc_attr(). You
|
||||
can threat it as a cookie that must be passed to dma_mmap_attrs() and
|
||||
dma_free_attrs(). Make sure that both of these also get this attribute
|
||||
set on each call.
|
||||
|
||||
Since it is optional for platforms to implement
|
||||
DMA_ATTR_NO_KERNEL_MAPPING, those that do not will simply ignore the
|
||||
attribute and exhibit default behavior.
|
||||
|
||||
DMA_ATTR_SKIP_CPU_SYNC
|
||||
----------------------
|
||||
|
||||
By default dma_map_{single,page,sg} functions family transfer a given
|
||||
buffer from CPU domain to device domain. Some advanced use cases might
|
||||
require sharing a buffer between more than one device. This requires
|
||||
having a mapping created separately for each device and is usually
|
||||
performed by calling dma_map_{single,page,sg} function more than once
|
||||
for the given buffer with device pointer to each device taking part in
|
||||
the buffer sharing. The first call transfers a buffer from 'CPU' domain
|
||||
to 'device' domain, what synchronizes CPU caches for the given region
|
||||
(usually it means that the cache has been flushed or invalidated
|
||||
depending on the dma direction). However, next calls to
|
||||
dma_map_{single,page,sg}() for other devices will perform exactly the
|
||||
same sychronization operation on the CPU cache. CPU cache sychronization
|
||||
might be a time consuming operation, especially if the buffers are
|
||||
large, so it is highly recommended to avoid it if possible.
|
||||
DMA_ATTR_SKIP_CPU_SYNC allows platform code to skip synchronization of
|
||||
the CPU cache for the given buffer assuming that it has been already
|
||||
transferred to 'device' domain. This attribute can be also used for
|
||||
dma_unmap_{single,page,sg} functions family to force buffer to stay in
|
||||
device domain after releasing a mapping for it. Use this attribute with
|
||||
care!

The basic interface to the MCA bus devices is the slot. Each slot

is numbered and virtual slot numbers are assigned to the internal

devices. Using a pci_dev as other busses do does not really make

sense in the MCA context as the MCA bus resources require card

specific interpretation.

1. Overview
|
||||
|
||||
Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
|
||||
for high-performance network applications such high-availability
|
||||
telecom systems. In addition to an XScale core, it contains up to 8
|
||||
"MicroEngines" that run special code, several high-end networking
|
||||
interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
|
||||
flash interface, and some other odds and ends. For more information, see:
|
||||
|
||||
http://developer.intel.com
|
||||
|
||||
2. Linux Support
|
||||
|
||||
Linux currently supports the following features on the IXP2000 NPUs:
|
||||
|
||||
- On-chip serial
|
||||
- PCI
|
||||
- Flash (MTD/JFFS2)
|
||||
- I2C through GPIO
|
||||
- Timers (watchdog, OS)
|
||||
|
||||

4. Usage Notes
|
||||
|
||||
- The IXP2000 platforms usually have rather complex PCI bus topologies
|
||||
with large memory space requirements. In addition, b/c of the way the
|
||||
Intel SDK is designed, devices are enumerated in a very specific
|
||||
way. B/c of this this, we use "pci=firmware" option in the kernel
|
||||
command line so that we do not re-enumerate the bus.
|
||||
|
||||
- IXDP2x01 systems have variable clock tick rates that we cannot determine
|
||||
via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
|
||||
to pass the clock rate to the board port.

||||

managers. These can be used when updating a display with CPU or system DMA.
|
||||
|
||||
omapdss driver support for audio
|
||||
--------------------------------
|
||||
There exist several display technologies and standards that support audio as
|
||||
well. Hence, it is relevant to update the DSS device driver to provide an audio
|
||||
interface that may be used by an audio driver or any other driver interested in
|
||||
the functionality.
|
||||
|
||||
The audio_enable function is intended to prepare the relevant
|
||||
IP for playback (e.g., enabling an audio FIFO, taking in/out of reset
|
||||
some IP, enabling companion chips, etc). It is intended to be called before
|
||||
audio_start. The audio_disable function performs the reverse operation and is
|
||||
intended to be called after audio_stop.
|
||||
|
||||
While a given DSS device driver may support audio, it is possible that for
|
||||
certain configurations audio is not supported (e.g., an HDMI display using a
|
||||
VESA video timing). The audio_supported function is intended to query whether
|
||||
the current configuration of the display supports audio.
|
||||
|
||||
The audio_config function is intended to configure all the relevant audio
|
||||
parameters of the display. In order to make the function independent of any
|
||||
specific DSS device driver, a struct omap_dss_audio is defined. Its purpose
|
||||
is to contain all the required parameters for audio configuration. At the
|
||||
moment, such structure contains pointers to IEC-60958 channel status word
|
||||
and CEA-861 audio infoframe structures. This should be enough to support
|
||||
HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958.
|
||||
|
||||
The audio_enable/disable, audio_config and audio_supported functions could be
|
||||
implemented as functions that may sleep. Hence, they should not be called
|
||||
while holding a spinlock or a readlock.
|
||||
|
||||
The audio_start/audio_stop function is intended to effectively start/stop audio
|
||||
playback after the configuration has taken place. These functions are designed
|
||||
to be used in an atomic context. Hence, audio_start should return quickly and be
|
||||
called only after all the needed resources for audio playback (audio FIFOs,
|
||||
DMA channels, companion chips, etc) have been enabled to begin data transfers.
|
||||
audio_stop is designed to only stop the audio transfers. The resources used
|
||||
for playback are released using audio_disable.
|
||||
|
||||
The enum omap_dss_audio_state may be used to help the implementations of
|
||||
the interface to keep track of the audio state. The initial state is _DISABLED;
|
||||
then, the state transitions to _CONFIGURED, and then, when it is ready to
|
||||
play audio, to _ENABLED. The state _PLAYING is used when the audio is being
|
||||
rendered.

HugeTLB Controller
|
||||
-------------------
|
||||
|
||||
The HugeTLB controller allows to limit the HugeTLB usage per control group and
|
||||
enforces the controller limit during page fault. Since HugeTLB doesn't
|
||||
support page reclaim, enforcing the limit at page fault time implies that,
|
||||
the application will get SIGBUS signal if it tries to access HugeTLB pages
|
||||
beyond its limit. This requires the application to know beforehand how much
|
||||
HugeTLB pages it would require for its use.
|
||||
|
||||
HugeTLB controller can be created by first mounting the cgroup filesystem.
|
||||
|
||||
# mount -t cgroup -o hugetlb none /sys/fs/cgroup
|
||||
|
||||
With the above step, the initial or the parent HugeTLB group becomes
|
||||
visible at /sys/fs/cgroup. At bootup, this group includes all the tasks in
|
||||
the system. /sys/fs/cgroup/tasks lists the tasks in this cgroup.
|
||||
|
||||
New groups can be created under the parent group /sys/fs/cgroup.
|
||||
|
||||
# cd /sys/fs/cgroup
|
||||
# mkdir g1
|
||||
# echo $$ > g1/tasks
|
||||
|
||||
The above steps create a new group g1 and move the current shell
|
||||
process (bash) into it.

||||
network CPU. For more information about CRIS and ETRAX please see further

below.
|
||||
This is a port of Linux to Axis Communications ETRAX 100LX,
|

ETRAX FS and ARTPEC-3 embedded network CPUs.
|
||||
|
||||
For more information about CRIS and ETRAX please see further below.
|
||||
|
||||
In order to compile this you need a version of gcc with support for the
|
||||
ETRAX chip family. Please see this link for more information on how to

What is CRIS ?
|
||||
--------------
|
||||
|
||||
CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU
|
||||
architecture in Axis Communication AB's range of embedded network CPU's,
|
||||
called ETRAX. The latest CPU is called ETRAX 100LX, where LX stands for
|
||||
'Linux' because the chip was designed to be a good host for the Linux
|
||||
operating system.
|
||||
called ETRAX.

|
||||
Axis shipping thin-servers like the Axis 2100 web camera or the ETRAX 100
|
||||
developer-board. It lacks an MMU so the Linux we run on that is a version
|
||||
of uClinux (Linux 2.0 without MM-support) ported to the CRIS architecture.
|

The new Linux 2.4 port has full MM and needs a CPU with an MMU, so it will

not run on the ETRAX 100.
|
||||
ETRAX 100LX is CRISv10 architecture.
|
||||

A version of the Axis developer-board with ETRAX 100LX (running Linux

The ETRAX FS and ARTPEC-3 chips
|
||||
-------------------------------
|
||||
|
||||
The ETRAX FS is a 200MHz 32-bit RISC processor with on-chip 16kB
|
||||
I-cache and 16kB D-cache and with a wide range of device interfaces
|
||||
including multiple high speed serial ports and an integrated USB 1.1 PHY.
|
||||
|
||||
The ARTPEC-3 is a variant of the ETRAX FS with additional IO-units
|
||||
used by the Axis Communications network cameras.

On-disk format

==============

Below is the recommended on-disk format. The verity kernel code does not

read the on-disk header. It only reads the hash blocks which directly

follow the header. It is expected that a user-space tool will verify the

integrity of the verity_header and then call dmsetup with the correct

* ARM architected timer
|
||||
|
||||
ARM Cortex-A7 and Cortex-A15 have a per-core architected timer, which
|
||||
provides per-cpu timers.
|
||||
|
||||
The timer is attached to a GIC to deliver its per-processor interrupts.
|
||||
|
||||
** Timer node properties:
|
||||
|
||||
- compatible : Should at least contain "arm,armv7-timer".
|
||||
|
||||
- interrupts : Interrupt list for secure, non-secure, virtual and
|
||||
hypervisor timers, in that order.
|
||||
|
||||
- clock-frequency : The frequency of the main counter, in Hz. Optional.
|
||||
|
||||
Example:
|
||||
|
||||
timer {

|
||||
"arm,armv7-timer";
|

* Samsung Exynos Interrupt Combiner Controller
|
||||
|
||||
Samsung's Exynos4 architecture includes a interrupt combiner controller which
|
||||
can combine interrupt sources as a group and provide a single interrupt request
|
||||
for the group. The interrupt request from each group are connected to a parent
|
||||
interrupt controller, such as GIC in case of Exynos4210.
|
||||
|
||||
The interrupt combiner controller consists of multiple combiners. Upto eight
|
||||
interrupt sources can be connected to a combiner. The combiner outputs one
|
||||
combined interrupt for its eight interrupt sources. The combined interrupt
|
||||
is usually connected to a parent interrupt controller.
|
||||
|
||||
A single node in the device tree is used to describe the interrupt combiner
|
||||
controller module (which includes multiple combiners). A combiner in the
|
||||
interrupt controller module shares config/control registers with other
|
||||
combiners. For example, a 32-bit interrupt enable/disable config register
|
||||
can accommodate upto 4 interrupt combiners (with each combiner supporting
|
||||
upto 8 interrupt sources).
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "samsung,exynos4210-combiner".
|
||||
- interrupt-controller: Identifies the node as an interrupt controller.
|
||||
- #interrupt-cells: should be <2>. The meaning of the cells are
|
||||
* First Cell: Combiner Group Number.
|
||||
* Second Cell: Interrupt number within the group.
|
||||
- reg: Base address and size of interrupt combiner registers.
|
||||
- interrupts: The list of interrupts generated by the combiners which are then
|
||||
connected to a parent interrupt controller. The format of the interrupt
|
||||
specifier depends in the interrupt parent controller.
|
||||
|
||||
Optional properties:
|
||||
- samsung,combiner-nr: The number of interrupt combiners supported. If this
|
||||
property is not specified, the default number of combiners is assumed
|
||||
to be 16.
|
||||
- interrupt-parent: pHandle of the parent interrupt controller, if not
|
||||
inherited from the parent node.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
The following is a an example from the Exynos4210 SoC dtsi file.
|
||||
|
||||
combiner:interrupt-controller@10440000 {
|

- #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:

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:
|
||||

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,
|
||||
