Handling Errors
DMA address space is limited on some architectures and an allocation
failure can be determined by:
- checking if dma_alloc_coherent returns NULL or dma_map_sg returns 0
- checking the returned dma_addr_t of dma_map_single and dma_map_page

* delay and try again later or
* reset driver.
*/
}
Networking drivers must call dev_kfree_skb to free the socket buffer
and return NETDEV_TX_OK if the DMA mapping fails on the transmit hook
(ndo_start_xmit). This means that the socket buffer is just dropped in
the failure case.
SCSI drivers must return SCSI_MLQUEUE_HOST_BUSY if the DMA mapping
fails in the queuecommand hook. This means that the SCSI subsystem
passes the command to the driver again later.

Struct scatterlist must contain, at a minimum, the following

2) ARCH_KMALLOC_MINALIGN
The base address is specified by a "page+offset" pair.
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_KMALLOC_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.
Previous versions of struct scatterlist contained a "void *address"
field that was sometimes used instead of page+offset. As of Linux
2.5., page+offset is always used, and the "address" field has been
deleted.

GPIOLIB conversion
------------------
If you need to convert your board or driver to use gpiolib from the exiting
s3c2410 api, then here are some notes on the process.
1) If your board is exclusively using an GPIO, say to control peripheral
power, then it will require to claim the gpio with gpio_request() before
it can use it.
It is recommended to check the return value, with at least WARN_ON()
during initialisation.
2) The s3c2410_gpio_cfgpin() can be directly replaced with s3c_gpio_cfgpin()
as they have the same arguments, and can either take the pin specific
values, or the more generic special-function-number arguments.
3) s3c2410_gpio_pullup() changs have the problem that whilst the
s3c2410_gpio_pullup(x, 1) can be easily translated to the
s3c_gpio_setpull(x, S3C_GPIO_PULL_NONE), the s3c2410_gpio_pullup(x, 0)
are not so easy.
The s3c2410_gpio_pullup(x, 0) case enables the pull-up (or in the case
of some of the devices, a pull-down) and as such the new API distinguishes
between the UP and DOWN case. There is currently no 'just turn on' setting
which may be required if this becomes a problem.
4) s3c2410_gpio_setpin() can be replaced by gpio_set_value(), the old call
does not implicitly configure the relevant gpio to output. The gpio
direction should be changed before using gpio_set_value().
5) s3c2410_gpio_getpin() is replaceable by gpio_get_value() if the pin
has been set to input. It is currently unknown what the behaviour is
when using gpio_get_value() on an output pin (s3c2410_gpio_getpin
would return the value the pin is supposed to be outputting).
6) s3c2410_gpio_getirq() should be directly replacable with the
gpio_to_irq() call.
The s3c2410_gpio and gpio_ calls have always operated on the same gpio
numberspace, so there is no problem with converting the gpio numbering
between the calls.

Samsung GPIO implementation
===========================
Introduction
------------
This outlines the Samsung GPIO implementation and the architecture
specfic calls provided alongisde the drivers/gpio core.
S3C24XX (Legacy)
----------------
See Documentation/arm/Samsung-S3C24XX/GPIO.txt for more information
about these devices. Their implementation is being brought into line
with the core samsung implementation described in this document.
GPIOLIB integration
-------------------
The gpio implementation uses gpiolib as much as possible, only providing
specific calls for the items that require Samsung specific handling, such
as pin special-function or pull resistor control.
GPIO numbering is synchronised between the Samsung and gpiolib system.
PIN configuration
-----------------
Pin configuration is specific to the Samsung architecutre, with each SoC
registering the necessary information for the core gpio configuration
implementation to configure pins as necessary.
The s3c_gpio_cfgpin() and s3c_gpio_setpull() provide the means for a
driver or machine to change gpio configuration.
See arch/arm/plat-samsung/include/plat/gpio-cfg.h for more information
on these functions.

unaccounted when it's removed from radix-tree. Even if RSS pages are fully

are really freed. Such SwapCaches also also accounted.
A swapped-in page is not accounted until it's mapped.
Note: The kernel does swapin-readahead and read multiple swaps at once.
This means swapped-in pages may contain pages for other tasks than a task
causing page fault. So, we avoid accounting at swap-in I/O.
At page migration, accounting information is kept.

testing on tmpfs will give you good numbers of small overheads.

The 'test_device_edac' sample driver is located at the
bluesmoke.sourceforge.net project site for EDAC.
=======================================================================
NEHALEM USAGE OF EDAC APIs
This chapter documents some EXPERIMENTAL mappings for EDAC API to handle
Nehalem EDAC driver. They will likely be changed on future versions
of the driver.
Due to the way Nehalem exports Memory Controller data, some adjustments
were done at i7core_edac driver. This chapter will cover those differences
1) On Nehalem, there are one Memory Controller per Quick Patch Interconnect
(QPI). At the driver, the term "socket" means one QPI. This is
associated with a physical CPU socket.
Each MC have 3 physical read channels, 3 physical write channels and
3 logic channels. The driver currenty sees it as just 3 channels.
Each channel can have up to 3 DIMMs.
The minimum known unity is DIMMs. There are no information about csrows.
As EDAC API maps the minimum unity is csrows, the driver sequencially
maps channel/dimm into different csrows.
For example, suposing the following layout:
Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
The driver will map it as:
csrow0: channel 0, dimm0
csrow1: channel 0, dimm1
csrow2: channel 1, dimm0
csrow3: channel 2, dimm0
exports one
DIMM per csrow.
Each QPI is exported as a different memory controller.
2) Nehalem MC has the hability to generate errors. The driver implements this
functionality via some error injection nodes:
For injecting a memory error, there are some sysfs nodes, under
/sys/devices/system/edac/mc/mc?/:
inject_addrmatch/*:
Controls the error injection mask register. It is possible to specify
several characteristics of the address to match an error code:
dimm = the affected dimm. Numbers are relative to a channel;
rank = the memory rank;
channel = the channel that will generate an error;
bank = the affected bank;
page = the page address;
column (or col) = the address column.
each of the above values can be set to "any" to match any valid value.
At driver init, all values are set to any.
For example, to generate an error at rank 1 of dimm 2, for any channel,
any bank, any page, any column:
echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
To return to the default behaviour of matching any, you can do:
echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
inject_eccmask:
specifies what bits will have troubles,
inject_section:
specifies what ECC cache section will get the error:
3 for both
2 for the highest
1 for the lowest
inject_type:
specifies the type of error, being a combination of the following bits:
bit 0 - repeat
bit 1 - ecc
bit 2 - parity
inject_enable starts the error generation when something different
than 0 is written.
All inject vars can be read. root permission is needed for write.
Datasheet states that the error will only be generated after a write on an
address that matches inject_addrmatch. It seems, however, that reading will
also produce an error.
For example, the following code will generate an error for any write access
at socket 0, on any DIMM/address on channel 2:
echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel
echo 2 >/sys/devices/system/edac/mc/mc0/inject_type
echo 64 >/sys/devices/system/edac/mc/mc0/inject_eccmask
echo 3 >/sys/devices/system/edac/mc/mc0/inject_section
echo 1 >/sys/devices/system/edac/mc/mc0/inject_enable
dd if=/dev/mem of=/dev/null seek=16k bs=4k count=1 >& /dev/null
For socket 1, it is needed to replace "mc0" by "mc1" at the above
commands.
The generated error message will look like:
EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
3) Nehalem specific Corrected Error memory counters
Nehalem have some registers to count memory errors. The driver uses those
registers to report Corrected Errors on devices with Registered Dimms.
However, those counters don't work with Unregistered Dimms. As the chipset
offers some counters that also work with UDIMMS (but with a worse level of
granularity than the default ones), the driver exposes those registers for
UDIMM memories.
They can be read by looking at the contents of all_channel_counts/
$ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
0
What happens here is that errors on different csrows, but at the same
dimm number will increment the same counter.
So, in this memory mapping:
csrow0: channel 0, dimm0
csrow1: channel 0, dimm1
csrow2: channel 1, dimm0
csrow3: channel 2, dimm0
The hardware will increment udimm0 for an error at the first dimm at either
csrow0, csrow2 or csrow3;
The hardware will increment udimm1 for an error at the second dimm at either

used to locate these. This second index table for speed of access (and because
it is small) is read at mount time and cached in memory.
3.7 Xattr table
---------------
The xattr table contains extended attributes for each inode. The xattrs
for each inode are stored in a list, each list entry containing a type,
name and value field. The type field encodes the xattr prefix
("user.", "trusted." etc) and it also encodes how the name/value fields
should be interpreted. Currently the type indicates whether the value
is stored inline (in which case the value field contains the xattr value),
or if it is stored out of line (in which case the value field stores a
reference to where the actual value is stored). This allows large values
to be stored out of line improving scanning and lookup performance and it
also allows values to be de-duplicated, the value being stored once, and
all other occurences holding an out of line reference to that value.
The xattr lists are packed into compressed 8K metadata blocks.
To reduce overhead in inodes, rather than storing the on-disk
location of the xattr list inside each inode, a 32-bit xattr id
is stored. This xattr id is mapped into the location of the xattr
list using a second xattr id lookup table.

Description
-----------
The Texas Instruments TMP102 implements one temperature sensor. Limits can be
set through the Overtemperature Shutdown register and Hysteresis register. The
sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
operating temperature has a minimum of -55 C and a maximum of +150 C.
The TMP102 has a programmable update rate that can select between 8, 4, 1, and
0.5 Hz. (Currently the driver only supports the default of 4 Hz).
The driver provides the common sysfs-interface for temperatures (see

Started Nov 1999 by Kanoj Sarcar <kanoj@sgi.com>
The intent of this file is to have an uptodate, running commentary
from different people about NUMA specific code in the Linux vm.
What is NUMA?
What is NUMA? It is an architecture where the memory access times
for different regions of memory from a given processor varies
according to the "distance" of the memory region from the processor.
Each region of memory to which access times are the same from any
cpu, is called a node. On such architectures, it is beneficial if
the kernel tries to minimize inter node communications. Schemes
for this range from kernel text and read-only data replication
across nodes, and trying to house all the data structures that
key components of the kernel need on memory on that node.
This question can be answered from a couple of perspectives: the
hardware view and the Linux software view.
Currently, all the numa support is to provide efficient handling
of widely discontiguous physical memory, so architectures which
are not NUMA but can have huge holes in the physical address space
can use the same code. All this code is bracketed by CONFIG_DISCONTIGMEM.
From the hardware perspective, a NUMA system is a computer platform that
comprises multiple components or assemblies each of which may contain 0
or more CPUs, local memory, and/or IO buses. For brevity and to
disambiguate the hardware view of these physical components/assemblies
from the software abstraction thereof, we'll call the components/assemblies
'cells' in this document.
The initial port includes NUMAizing the bootmem allocator code by
encapsulating all the pieces of information into a bootmem_data_t
structure. Node specific calls have been added to the allocator.
In theory, any platform which uses the bootmem allocator should
be able to put the bootmem and mem_map data structures anywhere
it deems best.
Each of the 'cells' may be viewed as an SMP [symmetric multi-processor] subset
of the system--although some components necessary for a stand-alone SMP system
may not be populated on any given cell. The cells of the NUMA system are
connected together with some sort of system interconnect--e.g., a crossbar or
point-to-point link are common types of NUMA system interconnects. Both of
these types of interconnects can be aggregated to create NUMA platforms with
cells at multiple distances from other cells.
Each node's page allocation data structures have also been encapsulated
into a pg_data_t. The bootmem_data_t is just one part of this. To
make the code look uniform between NUMA and regular UMA platforms,
UMA platforms have a statically allocated pg_data_t too (contig_page_data).
For the sake of uniformity, the function num_online_nodes() is also defined
for all platforms. As we run benchmarks, we might decide to NUMAize
more variables like low_on_memory, nr_free_pages etc into the pg_data_t.
For Linux, the NUMA platforms of interest are primarily what is known as Cache
Coherent NUMA or ccNUMA systems. With ccNUMA systems, all memory is visible
to and accessible from any CPU attached to any cell and cache coherency
is handled in hardware by the processor caches and/or the system interconnect.
The NUMA aware page allocation code currently tries to allocate pages
from different nodes in a round robin manner. This will be changed to
do concentratic circle search, starting from current node, once the
NUMA port achieves more maturity. The call alloc_pages_node has been
added, so that drivers can make the call and not worry about whether
it is running on a NUMA or UMA platform.
Memory access time and effective memory bandwidth varies depending on how far
away the cell containing the CPU or IO bus making the memory access is from the
cell containing the target memory. For example, access to memory by CPUs
attached to the same cell will experience faster access times and higher
bandwidths than accesses to memory on other, remote cells. NUMA platforms
can have cells at multiple remote distances from any given cell.
Platform vendors don't build NUMA systems just to make software developers'
lives interesting. Rather, this architecture is a means to provide scalable
memory bandwidth. However, to achieve scalable memory bandwidth, system and
application software must arrange for a large majority of the memory references
[cache misses] to be to "local" memory--memory on the same cell, if any--or
to the closest cell with memory.
This leads to the Linux software view of a NUMA system:
Linux divides the system's hardware resources into multiple software
abstractions called "nodes". Linux maps the nodes onto the physical cells
of the hardware platform, abstracting away some of the details for some
architectures. As with physical cells, software nodes may contain 0 or more
CPUs, memory and/or IO buses. And, again, memory accesses to memory on
"closer" nodes--nodes that map to closer cells--will generally experience
faster access times and higher effective bandwidth than accesses to more
remote cells.
For some architectures, such as x86, Linux will "hide" any node representing a
physical cell that has no memory attached, and reassign any CPUs attached to
that cell to a node representing a cell that does have memory. Thus, on
these architectures, one cannot assume that all CPUs that Linux associates with
a given node will see the same local memory access times and bandwidth.
In addition, for some architectures, again x86 is an example, Linux supports
the emulation of additional nodes. For NUMA emulation, linux will carve up
the existing nodes--or the system memory for non-NUMA platforms--into multiple
nodes. Each emulated node will manage a fraction of the underlying cells'
physical memory. NUMA emluation is useful for testing NUMA kernel and
application features on non-NUMA platforms, and as a sort of memory resource
management mechanism when used together with cpusets.
[see Documentation/cgroups/cpusets.txt]
For each node with memory, Linux constructs an independent memory management
subsystem, complete with its own free page lists, in-use page lists, usage
statistics and locks to mediate access. In addition, Linux constructs for
each memory zone [one or more of DMA, DMA32, NORMAL, HIGH_MEMORY, MOVABLE],
an ordered "zonelist". A zonelist specifies the zones/nodes to visit when a
selected zone/node cannot satisfy the allocation request. This situation,
when a zone has no available memory to satisfy a request, is called
"overflow" or "fallback".
Because some nodes contain multiple zones containing different types of
memory, Linux must decide whether to order the zonelists such that allocations
fall back to the same zone type on a different node, or to a different zone
type on the same node. This is an important consideration because some zones,
such as DMA or DMA32, represent relatively scarce resources. Linux chooses
a default zonelist order based on the sizes of the various zone types relative
to the total memory of the node and the total memory of the system. The
default zonelist order may be overridden using the numa_zonelist_order kernel
boot parameter or sysctl. [see Documentation/kernel-parameters.txt and
Documentation/sysctl/vm.txt]
By default, Linux will attempt to satisfy memory allocation requests from the
node to which the CPU that executes the request is assigned. Specifically,
Linux will attempt to allocate from the first node in the appropriate zonelist
for the node where the request originates. This is called "local allocation."
If the "local" node cannot satisfy the request, the kernel will examine other
nodes' zones in the selected zonelist looking for the first zone in the list
that can satisfy the request.
Local allocation will tend to keep subsequent access to the allocated memory
"local" to the underlying physical resources and off the system interconnect--
as long as the task on whose behalf the kernel allocated some memory does not
later migrate away from that memory. The Linux scheduler is aware of the
NUMA topology of the platform--embodied in the "scheduling domains" data
structures [see Documentation/scheduler/sched-domains.txt]--and the scheduler
attempts to minimize task migration to distant scheduling domains. However,
the scheduler does not take a task's NUMA footprint into account directly.
Thus, under sufficient imbalance, tasks can migrate between nodes, remote
from their initial node and kernel data structures.
System administrators and application designers can restrict a task's migration
to improve NUMA locality using various CPU affinity command line interfaces,
such as taskset(1) and numactl(1), and program interfaces such as
sched_setaffinity(2). Further, one can modify the kernel's default local
allocation behavior using Linux NUMA memory policy.
[see Documentation/vm/numa_memory_policy.]
System administrators can restrict the CPUs and nodes' memories that a non-
privileged user can specify in the scheduling or NUMA commands and functions
using control groups and CPUsets. [see Documentation/cgroups/CPUsets.txt]
On architectures that do not hide memoryless nodes, Linux will include only
zones [nodes] with memory in the zonelists. This means that for a memoryless
node the "local memory node"--the node of the first zone in CPU's node's
zonelist--will not be the node itself. Rather, it will be the node that the
kernel selected as the nearest node with memory when it built the zonelists.
So, default, local allocations will succeed with the kernel supplying the
closest available memory. This is a consequence of the same mechanism that
allows such allocations to fallback to other nearby nodes when a node that
does contain memory overflows.
Some kernel allocations do not want or cannot tolerate this allocation fallback
behavior. Rather they want to be sure they get memory from the specified node
or get notified that the node has no free memory. This is usually the case when
a subsystem allocates per CPU memory resources, for example.
A typical model for making such an allocation is to obtain the node id of the
node to which the "current CPU" is attached using one of the kernel's
numa_node_id() or CPU_to_node() functions and then request memory from only
the node id returned. When such an allocation fails, the requesting subsystem
may revert to its own fallback path. The slab kernel memory allocator is an
example of this. Or, the subsystem may choose to disable or not to enable
itself on allocation failure. The kernel profiling subsystem is an example of
this.
If the architecture supports--does not hide--memoryless nodes, then CPUs
attached to memoryless nodes would always incur the fallback path overhead
or some subsystems would fail to initialize if they attempted to allocated
memory exclusively from a node without memory. To support such
architectures transparently, kernel subsystems can use the numa_mem_id()
or cpu_to_mem() function to locate the "local memory node" for the calling or
specified CPU. Again, this is the same node from which default, local page
allocations will be attempted.
