================
CIRCULAR BUFFERS
================
By: David Howells <dhowells@redhat.com>
Paul E. McKenney <paulmck@linux.vnet.ibm.com>
Linux provides a number of features that can be used to implement circular
buffering. There are two sets of such features:
(1) Convenience functions for determining information about power-of-2 sized
buffers.
(2) Memory barriers for when the producer and the consumer of objects in the
buffer don't want to share a lock.
To use these facilities, as discussed below, there needs to be just one
producer and just one consumer. It is possible to handle multiple producers by
serialising them, and to handle multiple consumers by serialising them.
Contents:
(*) What is a circular buffer?
(*) Measuring power-of-2 buffers.
(*) Using memory barriers with circular buffers.
- The producer.
- The consumer.
==========================
WHAT IS A CIRCULAR BUFFER?
==========================
First of all, what is a circular buffer? A circular buffer is a buffer of
fixed, finite size into which there are two indices:
(1) A 'head' index - the point at which the producer inserts items into the
buffer.
(2) A 'tail' index - the point at which the consumer finds the next item in
the buffer.
Typically when the tail pointer is equal to the head pointer, the buffer is
empty; and the buffer is full when the head pointer is one less than the tail
pointer.
The head index is incremented when items are added, and the tail index when
items are removed. The tail index should never jump the head index, and both
indices should be wrapped to 0 when they reach the end of the buffer, thus
allowing an infinite amount of data to flow through the buffer.
Typically, items will all be of the same unit size, but this isn't strictly
required to use the techniques below. The indices can be increased by more
than 1 if multiple items or variable-sized items are to be included in the
buffer, provided that neither index overtakes the other. The implementer must
be careful, however, as a region more than one unit in size may wrap the end of
the buffer and be broken into two segments.
============================
MEASURING POWER-OF-2 BUFFERS
============================
Calculation of the occupancy or the remaining capacity of an arbitrarily sized
circular buffer would normally be a slow operation, requiring the use of a
modulus (divide) instruction. However, if the buffer is of a power-of-2 size,
then a much quicker bitwise-AND instruction can be used instead.
Linux provides a set of macros for handling power-of-2 circular buffers. These
can be made use of by:
#include <linux/circ_buf.h>
The macros are:
(*) Measure the remaining capacity of a buffer:
CIRC_SPACE(head_index, tail_index, buffer_size);
This returns the amount of space left in the buffer[1] into which items
can be inserted.
(*) Measure the maximum consecutive immediate space in a buffer:
CIRC_SPACE_TO_END(head_index, tail_index, buffer_size);
This returns the amount of consecutive space left in the buffer[1] into
which items can be immediately inserted without having to wrap back to the
beginning of the buffer.
(*) Measure the occupancy of a buffer:
CIRC_CNT(head_index, tail_index, buffer_size);
This returns the number of items currently occupying a buffer[2].
(*) Measure the non-wrapping occupancy of a buffer:
CIRC_CNT_TO_END(head_index, tail_index, buffer_size);
This returns the number of consecutive items[2] that can be extracted from
the buffer without having to wrap back to the beginning of the buffer.
Each of these macros will nominally return a value between 0 and buffer_size-1,
however:
[1] CIRC_SPACE*() are intended to be used in the producer. To the producer
they will return a lower bound as the producer controls the head index,
but the consumer may still be depleting the buffer on another CPU and
moving the tail index.
To the consumer it will show an upper bound as the producer may be busy
depleting the space.
[2] CIRC_CNT*() are intended to be used in the consumer. To the consumer they
will return a lower bound as the consumer controls the tail index, but the
producer may still be filling the buffer on another CPU and moving the
head index.
To the producer it will show an upper bound as the consumer may be busy
emptying the buffer.
[3] To a third party, the order in which the writes to the indices by the
producer and consumer become visible cannot be guaranteed as they are
independent and may be made on different CPUs - so the result in such a
situation will merely be a guess, and may even be negative.
===========================================
USING MEMORY BARRIERS WITH CIRCULAR BUFFERS
===========================================
By using memory barriers in conjunction with circular buffers, you can avoid
the need to:
(1) use a single lock to govern access to both ends of the buffer, thus
allowing the buffer to be filled and emptied at the same time; and
(2) use atomic counter operations.
There are two sides to this: the producer that fills the buffer, and the
consumer that empties it. Only one thing should be filling a buffer at any one
time, and only one thing should be emptying a buffer at any one time, but the
two sides can operate simultaneously.
THE PRODUCER
------------
The producer will look something like this:
spin_lock(&producer_lock);
unsigned long head = buffer->head;
unsigned long tail = ACCESS_ONCE(buffer->tail);
if (CIRC_SPACE(head, tail, buffer->size) >= 1) {
/* insert one item into the buffer */
struct item *item = buffer[head];
produce_item(item);
smp_wmb(); /* commit the item before incrementing the head */
buffer->head = (head + 1) & (buffer->size - 1);
/* wake_up() will make sure that the head is committed before
* waking anyone up */
wake_up(consumer);
}
spin_unlock(&producer_lock);
This will instruct the CPU that the contents of the new item must be written
before the head index makes it available to the consumer and then instructs the
CPU that the revised head index must be written before the consumer is woken.
Note that wake_up() doesn't have to be the exact mechanism used, but whatever
is used must guarantee a (write) memory barrier between the update of the head
index and the change of state of the consumer, if a change of state occurs.
THE CONSUMER
------------
The consumer will look something like this:
spin_lock(&consumer_lock);
unsigned long head = ACCESS_ONCE(buffer->head);
unsigned long tail = buffer->tail;
if (CIRC_CNT(head, tail, buffer->size) >= 1) {
/* read index before reading contents at that index */
smp_read_barrier_depends();
/* extract one item from the buffer */
struct item *item = buffer[tail];
consume_item(item);
smp_mb(); /* finish reading descriptor before incrementing tail */
buffer->tail = (tail + 1) & (buffer->size - 1);
}
spin_unlock(&consumer_lock);
This will instruct the CPU to make sure the index is up to date before reading
the new item, and then it shall make sure the CPU has finished reading the item
before it writes the new tail pointer, which will erase the item.
Note the use of ACCESS_ONCE() in both algorithms to read the opposition index.
This prevents the compiler from discarding and reloading its cached value -
which some compilers will do across smp_read_barrier_depends(). This isn't
strictly needed if you can be sure that the opposition index will _only_ be
used the once.

Why: The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.
In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.
The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

STMicroelectronics 10/100/1000 Synopsys Ethernet driver
Copyright (C) 2007-2010 STMicroelectronics Ltd
Author: Giuseppe Cavallaro <peppe.cavallaro@st.com>
This is the driver for the MAC 10/100/1000 on-chip Ethernet controllers
(Synopsys IP blocks); it has been fully tested on STLinux platforms.
Currently this network device driver is for all STM embedded MAC/GMAC
(7xxx SoCs).
DWC Ether MAC 10/100/1000 Universal version 3.41a and DWC Ether MAC 10/100
Universal version 4.0 have been used for developing the first code
implementation.
Please, for more information also visit: www.stlinux.com
1) Kernel Configuration
The kernel configuration option is STMMAC_ETH:
Device Drivers ---> Network device support ---> Ethernet (1000 Mbit) --->
STMicroelectronics 10/100/1000 Ethernet driver (STMMAC_ETH)
2) Driver parameters list:
debug: message level (0: no output, 16: all);
phyaddr: to manually provide the physical address to the PHY device;
dma_rxsize: DMA rx ring size;
dma_txsize: DMA tx ring size;
buf_sz: DMA buffer size;
tc: control the HW FIFO threshold;
tx_coe: Enable/Disable Tx Checksum Offload engine;
watchdog: transmit timeout (in milliseconds);
flow_ctrl: Flow control ability [on/off];
pause: Flow Control Pause Time;
tmrate: timer period (only if timer optimisation is configured).
3) Command line options
Driver parameters can be also passed in command line by using:
stmmaceth=dma_rxsize:128,dma_txsize:512
4) Driver information and notes
4.1) Transmit process
The xmit method is invoked when the kernel needs to transmit a packet; it sets
the descriptors in the ring and informs the DMA engine that there is a packet
ready to be transmitted.
Once the controller has finished transmitting the packet, an interrupt is
triggered; So the driver will be able to release the socket buffers.
By default, the driver sets the NETIF_F_SG bit in the features field of the
net_device structure enabling the scatter/gather feature.
4.2) Receive process
When one or more packets are received, an interrupt happens. The interrupts
are not queued so the driver has to scan all the descriptors in the ring during
the receive process.
This is based on NAPI so the interrupt handler signals only if there is work to be
done, and it exits.
Then the poll method will be scheduled at some future point.
The incoming packets are stored, by the DMA, in a list of pre-allocated socket
buffers in order to avoid the memcpy (Zero-copy).
4.3) Timer-Driver Interrupt
Instead of having the device that asynchronously notifies the frame receptions, the
driver configures a timer to generate an interrupt at regular intervals.
Based on the granularity of the timer, the frames that are received by the device
will experience different levels of latency. Some NICs have dedicated timer
device to perform this task. STMMAC can use either the RTC device or the TMU
channel 2 on STLinux platforms.
The timers frequency can be passed to the driver as parameter; when change it,
take care of both hardware capability and network stability/performance impact.
Several performance tests on STM platforms showed this optimisation allows to spare
the CPU while having the maximum throughput.
4.4) WOL
Wake up on Lan feature through Magic Frame is only supported for the GMAC
core.
4.5) DMA descriptors
Driver handles both normal and enhanced descriptors. The latter has been only
tested on DWC Ether MAC 10/100/1000 Universal version 3.41a.
4.6) Ethtool support
Ethtool is supported. Driver statistics and internal errors can be taken using:
ethtool -S ethX command. It is possible to dump registers etc.
4.7) Jumbo and Segmentation Offloading
Jumbo frames are supported and tested for the GMAC.
The GSO has been also added but it's performed in software.
LRO is not supported.
4.8) Physical
The driver is compatible with PAL to work with PHY and GPHY devices.
4.9) Platform information
Several information came from the platform; please refer to the
driver's Header file in include/linux directory.
struct plat_stmmacenet_data {
int bus_id;
int pbl;
int has_gmac;
void (*fix_mac_speed)(void *priv, unsigned int speed);
void (*bus_setup)(unsigned long ioaddr);
#ifdef CONFIG_STM_DRIVERS
struct stm_pad_config *pad_config;
#endif
void *bsp_priv;
};
Where:
- pbl (Programmable Burst Length) is maximum number of
beats to be transferred in one DMA transaction.
GMAC also enables the 4xPBL by default.
- fix_mac_speed and bus_setup are used to configure internal target
registers (on STM platforms);
- has_gmac: GMAC core is on board (get it at run-time in the next step);
- bus_id: bus identifier.
struct plat_stmmacphy_data {
int bus_id;
int phy_addr;
unsigned int phy_mask;
int interface;
int (*phy_reset)(void *priv);
void *priv;
};
Where:
- bus_id: bus identifier;
- phy_addr: physical address used for the attached phy device;
set it to -1 to get it at run-time;
- interface: physical MII interface mode;
- phy_reset: hook to reset HW function.
TODO:
- Continue to make the driver more generic and suitable for other Synopsys
Ethernet controllers used on other architectures (i.e. ARM).
- 10G controllers are not supported.
- MAC uses Normal descriptors and GMAC uses enhanced ones.
This is a limit that should be reviewed. MAC could want to
use the enhanced structure.
- Checksumming: Rx/Tx csum is done in HW in case of GMAC only.
- Review the timer optimisation code to use an embedded device that seems to be
available in new chip generations.

DEVICE IMPLEMENTATION
A driver which supports hardware time stamping must support the
SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
in the skb with skb_hwtstamp_set().
SIOCSHWTSTAMP ioctl and update the supplied struct hwtstamp_config with
the actual values as described in the section on SIOCSHWTSTAMP.
Time stamps for received packets must be stored in the skb. To get a pointer
to the shared time stamp structure of the skb call skb_hwtstamps(). Then
set the time stamps in the structure:
struct skb_shared_hwtstamps {
/* hardware time stamp transformed into duration
* since arbitrary point in time
*/
ktime_t hwtstamp;
ktime_t syststamp; /* hwtstamp transformed to system time base */
};
Time stamps for outgoing packets are to be generated as follows:
- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
returns non-zero. If yes, then the driver is expected
to do hardware time stamping.
- In hard_start_xmit(), check if skb_tx(skb)->hardware is set no-zero.
If yes, then the driver is expected to do hardware time stamping.
- If this is possible for the skb and requested, then declare
that the driver is doing the time stamping by calling
skb_hwtstamp_tx_in_progress(). A driver not supporting
hardware time stamping doesn't do that. A driver must never
touch sk_buff::tstamp! It is used to store how time stamping
for an outgoing packets is to be done.
that the driver is doing the time stamping by setting the field
skb_tx(skb)->in_progress non-zero. You might want to keep a pointer
to the associated skb for the next step and not free the skb. A driver
not supporting hardware time stamping doesn't do that. A driver must
never touch sk_buff::tstamp! It is used to store software generated
time stamps by the network subsystem.
- As soon as the driver has sent the packet and/or obtained a
hardware time stamp for it, it passes the time stamp back by
calling skb_hwtstamp_tx() with the original skb, the raw
hardware time stamp and a handle to the device (necessary
to convert the hardware time stamp to system time). If obtaining
the hardware time stamp somehow fails, then the driver should
not fall back to software time stamping. The rationale is that
this would occur at a later time in the processing pipeline
than other software time stamping and therefore could lead
to unexpected deltas between time stamps.
- If the driver did not call skb_hwtstamp_tx_in_progress(), then
hardware time stamp. skb_hwtstamp_tx() clones the original skb and
adds the timestamps, therefore the original skb has to be freed now.
If obtaining the hardware time stamp somehow fails, then the driver
should not fall back to software time stamping. The rationale is that
this would occur at a later time in the processing pipeline than other

- If the driver did not call set skb_tx(skb)->in_progress, then
dev_hard_start_xmit() checks whether software time stamping
is wanted as fallback and potentially generates the time stamp.

Interrupt Handling
~~~~~~~~~~~~~~~~~~
In rare but some cases, the interrupt isn't properly handled as
default. You would notice this by the DMA transfer error reported by
ALSA PCM core, for example. Using MSI might help in such a case.
Pass `enable_msi=1` option for enabling MSI.
HD-audio driver uses MSI as default (if available) since 2.6.33
kernel as MSI works better on some machines, and in general, it's
better for performance. However, Nvidia controllers showed bad
regressions with MSI (especially in a combination with AMD chipset),
thus we disabled MSI for them.
There seem also still other devices that don't work with MSI. If you
see a regression wrt the sound quality (stuttering, etc) or a lock-up
in the recent kernel, try to pass `enable_msi=0` option to disable
MSI. If it works, you can add the known bad device to the blacklist
defined in hda_intel.c. In such a case, please report and give the
patch back to the upstream developer.
