Altera Triple-Speed Ethernet MAC driver
Copyright (C) 2008-2014 Altera Corporation
This is the driver for the Altera Triple-Speed Ethernet (TSE) controllers
using the SGDMA and MSGDMA soft DMA IP components. The driver uses the
platform bus to obtain component resources. The designs used to test this
driver were built for a Cyclone(R) V SOC FPGA board, a Cyclone(R) V FPGA board,
and tested with ARM and NIOS processor hosts seperately. The anticipated use
cases are simple communications between an embedded system and an external peer
for status and simple configuration of the embedded system.
For more information visit www.altera.com and www.rocketboards.org. Support
forums for the driver may be found on www.rocketboards.org, and a design used
to test this driver may be found there as well. Support is also available from
the maintainer of this driver, found in MAINTAINERS.
The Triple-Speed Ethernet, SGDMA, and MSGDMA components are all soft IP
components that can be assembled and built into an FPGA using the Altera
Quartus toolchain. Quartus 13.1 and 14.0 were used to build the design that
this driver was tested against. The sopc2dts tool is used to create the
device tree for the driver, and may be found at rocketboards.org.
The driver probe function examines the device tree and determines if the
Triple-Speed Ethernet instance is using an SGDMA or MSGDMA component. The
probe function then installs the appropriate set of DMA routines to
initialize, setup transmits, receives, and interrupt handling primitives for
the respective configurations.
The SGDMA component is to be deprecated in the near future (over the next 1-2
years as of this writing in early 2014) in favor of the MSGDMA component.
SGDMA support is included for existing designs and reference in case a
developer wishes to support their own soft DMA logic and driver support. Any
new designs should not use the SGDMA.
The SGDMA supports only a single transmit or receive operation at a time, and
therefore will not perform as well compared to the MSGDMA soft IP. Please
visit www.altera.com for known, documented SGDMA errata.
Scatter-gather DMA is not supported by the SGDMA or MSGDMA at this time.
Scatter-gather DMA will be added to a future maintenance update to this
driver.
Jumbo frames are not supported at this time.
The driver limits PHY operations to 10/100Mbps, and has not yet been fully
tested for 1Gbps. This support will be added in a future maintenance update.
1) Kernel Configuration
The kernel configuration option is ALTERA_TSE:
Device Drivers ---> Network device support ---> Ethernet driver support --->
Altera Triple-Speed Ethernet MAC support (ALTERA_TSE)
2) Driver parameters list:
debug: message level (0: no output, 16: all);
dma_rx_num: Number of descriptors in the RX list (default is 64);
dma_tx_num: Number of descriptors in the TX list (default is 64).
3) Command line options
Driver parameters can be also passed in command line by using:
altera_tse=dma_rx_num:128,dma_tx_num:512
4) Driver information and notes
4.1) Transmit process
When the driver's transmit routine is called by the kernel, it sets up a
transmit descriptor by calling the underlying DMA transmit routine (SGDMA or
MSGDMA), and initites a transmit operation. Once the transmit is complete, an
interrupt is driven by the transmit DMA logic. The driver handles the transmit
completion in the context of the interrupt handling chain by recycling
resource required to send and track the requested transmit operation.
4.2) Receive process
The driver will post receive buffers to the receive DMA logic during driver
intialization. Receive buffers may or may not be queued depending upon the
underlying DMA logic (MSGDMA is able queue receive buffers, SGDMA is not able
to queue receive buffers to the SGDMA receive logic). When a packet is
received, the DMA logic generates an interrupt. The driver handles a receive
interrupt by obtaining the DMA receive logic status, reaping receive
completions until no more receive completions are available.
4.3) Interrupt Mitigation
The driver is able to mitigate the number of its DMA interrupts
using NAPI for receive operations. Interrupt mitigation is not yet supported
for transmit operations, but will be added in a future maintenance release.
4.4) 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.
4.5) PHY Support
The driver is compatible with PAL to work with PHY and GPHY devices.
4.7) List of source files:
o Kconfig
o Makefile
o altera_tse_main.c: main network device driver
o altera_tse_ethtool.c: ethtool support
o altera_tse.h: private driver structure and common definitions

5) Debug Information
The driver exports debug information such as internal statistics,
debug information, MAC and DMA registers etc.
A user may use the ethtool support to get statistics:
e.g. using: ethtool -S ethX (that shows the statistics counters)
or sees the MAC registers: e.g. using: ethtool -d ethX
The developer can also use the "debug" module parameter to get
further debug information.
6) Statistics Support
The controller and driver support a mix of IEEE standard defined statistics,
RFC defined statistics, and driver or Altera defined statistics. The four
specifications containing the standard definitions for these statistics are
as follows:
o IEEE 802.3-2012 - IEEE Standard for Ethernet.
o RFC 2863 found at http://www.rfc-editor.org/rfc/rfc2863.txt.
o RFC 2819 found at http://www.rfc-editor.org/rfc/rfc2819.txt.
o Altera Triple Speed Ethernet User Guide, found at http://www.altera.com
The statistics supported by the TSE and the device driver are as follows:
"tx_packets" is equivalent to aFramesTransmittedOK defined in IEEE 802.3-2012,
Section 5.2.2.1.2. This statistics is the count of frames that are successfully
transmitted.
"rx_packets" is equivalent to aFramesReceivedOK defined in IEEE 802.3-2012,

length errors, or alignment errors.
"rx_crc_errors" is equivalent to aFrameCheckSequenceErrors defined in IEEE
802.3-2012, Section 5.2.2.1.6. This statistic is the count of frames that are
an integral number of bytes in length and do not pass the CRC test as the frame
is received.
"rx_align_errors" is equivalent to aAlignmentErrors defined in IEEE 802.3-2012,
Section 5.2.2.1.7. This statistic is the count of frames that are not an

For BPF JIT developers, bpf_jit_disasm, bpf_asm and bpf_dbg provides a useful
toolchain for developing and testing the kernel's JIT compiler.
BPF kernel internals
--------------------
Internally, for the kernel interpreter, a different BPF instruction set
format with similar underlying principles from BPF described in previous
paragraphs is being used. However, the instruction set format is modelled
closer to the underlying architecture to mimic native instruction sets, so
that a better performance can be achieved (more details later).
It is designed to be JITed with one to one mapping, which can also open up
the possibility for GCC/LLVM compilers to generate optimized BPF code through
a BPF backend that performs almost as fast as natively compiled code.
The new instruction set was originally designed with the possible goal in
mind to write programs in "restricted C" and compile into BPF with a optional
GCC/LLVM backend, so that it can just-in-time map to modern 64-bit CPUs with
minimal performance overhead over two steps, that is, C -> BPF -> native code.
Currently, the new format is being used for running user BPF programs, which
includes seccomp BPF, classic socket filters, cls_bpf traffic classifier,
team driver's classifier for its load-balancing mode, netfilter's xt_bpf
extension, PTP dissector/classifier, and much more. They are all internally
converted by the kernel into the new instruction set representation and run
in the extended interpreter. For in-kernel handlers, this all works
transparently by using sk_unattached_filter_create() for setting up the
filter, resp. sk_unattached_filter_destroy() for destroying it. The macro
SK_RUN_FILTER(filter, ctx) transparently invokes the right BPF function to
run the filter. 'filter' is a pointer to struct sk_filter that we got from
sk_unattached_filter_create(), and 'ctx' the given context (e.g. skb pointer).
All constraints and restrictions from sk_chk_filter() apply before a
conversion to the new layout is being done behind the scenes!
Currently, for JITing, the user BPF format is being used and current BPF JIT
compilers reused whenever possible. In other words, we do not (yet!) perform
a JIT compilation in the new layout, however, future work will successively
migrate traditional JIT compilers into the new instruction format as well, so
that they will profit from the very same benefits. Thus, when speaking about
JIT in the following, a JIT compiler (TBD) for the new instruction format is
meant in this context.
Some core changes of the new internal format:
- Number of registers increase from 2 to 10:
The old format had two registers A and X, and a hidden frame pointer. The
new layout extends this to be 10 internal registers and a read-only frame
pointer. Since 64-bit CPUs are passing arguments to functions via registers
the number of args from BPF program to in-kernel function is restricted
to 5 and one register is used to accept return value from an in-kernel
function. Natively, x86_64 passes first 6 arguments in registers, aarch64/
sparcv9/mips64 have 7 - 8 registers for arguments; x86_64 has 6 callee saved
registers, and aarch64/sparcv9/mips64 have 11 or more callee saved registers.
Therefore, BPF calling convention is defined as:
* R0 - return value from in-kernel function
* R1 - R5 - arguments from BPF program to in-kernel function
* R6 - R9 - callee saved registers that in-kernel function will preserve
* R10 - read-only frame pointer to access stack
Thus, all BPF registers map one to one to HW registers on x86_64, aarch64,
etc, and BPF calling convention maps directly to ABIs used by the kernel on
64-bit architectures.
On 32-bit architectures JIT may map programs that use only 32-bit arithmetic
and may let more complex programs to be interpreted.
R0 - R5 are scratch registers and BPF program needs spill/fill them if
necessary across calls. Note that there is only one BPF program (== one BPF
main routine) and it cannot call other BPF functions, it can only call
predefined in-kernel functions, though.
- Register width increases from 32-bit to 64-bit:
Still, the semantics of the original 32-bit ALU operations are preserved
via 32-bit subregisters. All BPF registers are 64-bit with 32-bit lower
subregisters that zero-extend into 64-bit if they are being written to.
That behavior maps directly to x86_64 and arm64 subregister definition, but
makes other JITs more difficult.
32-bit architectures run 64-bit internal BPF programs via interpreter.
Their JITs may convert BPF programs that only use 32-bit subregisters into
native instruction set and let the rest being interpreted.
Operation is 64-bit, because on 64-bit architectures, pointers are also
64-bit wide, and we want to pass 64-bit values in/out of kernel functions,
so 32-bit BPF registers would otherwise require to define register-pair
ABI, thus, there won't be able to use a direct BPF register to HW register
mapping and JIT would need to do combine/split/move operations for every
register in and out of the function, which is complex, bug prone and slow.
Another reason is the use of atomic 64-bit counters.
- Conditional jt/jf targets replaced with jt/fall-through:
While the original design has constructs such as "if (cond) jump_true;
else jump_false;", they are being replaced into alternative constructs like
"if (cond) jump_true; /* else fall-through */".
- Introduces bpf_call insn and register passing convention for zero overhead
calls from/to other kernel functions:
After a kernel function call, R1 - R5 are reset to unreadable and R0 has a
return type of the function. Since R6 - R9 are callee saved, their state is
preserved across the call.
Also in the new design, BPF is limited to 4096 insns, which means that any
program will terminate quickly and will only call a fixed number of kernel
functions. Original BPF and the new format are two operand instructions,
which helps to do one-to-one mapping between BPF insn and x86 insn during JIT.
The input context pointer for invoking the interpreter function is generic,
its content is defined by a specific use case. For seccomp register R1 points
to seccomp_data, for converted BPF filters R1 points to a skb.
A program, that is translated internally consists of the following elements:
op:16, jt:8, jf:8, k:32 ==> op:8, a_reg:4, x_reg:4, off:16, imm:32
Just like the original BPF, the new format runs within a controlled environment,
is deterministic and the kernel can easily prove that. The safety of the program
can be determined in two steps: first step does depth-first-search to disallow
loops and other CFG validation; second step starts from the first insn and
descends all possible paths. It simulates execution of every insn and observes
the state change of registers and stack.

The Gianfar Ethernet Driver
Sysfs File description
Author: Andy Fleming <afleming@freescale.com>
Updated: 2005-07-28
SYSFS
Several of the features of the gianfar driver are controlled
through sysfs files. These are:
bd_stash:
To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to
bd_stash, echo 'off' or '0' to disable
rx_stash_len:
To stash the first n bytes of the packet in L2, echo the number
of bytes to buf_stash_len. echo 0 to disable.
WARNING: You could really screw these up if you set them too low or high!
fifo_threshold:
To change the number of bytes the controller needs in the
fifo before it starts transmission, echo the number of bytes to
fifo_thresh. Range should be 0-511.
fifo_starve:
When the FIFO has less than this many bytes during a transmit, it
enters starve mode, and increases the priority of TX memory
transactions. To change, echo the number of bytes to
fifo_starve. Range should be 0-511.
fifo_starve_off:
Once in starve mode, the FIFO remains there until it has this
many bytes. To change, echo the number of bytes to
fifo_starve_off. Range should be 0-511.

=======================
CONFIGURABLE PARAMETERS
=======================
The RxRPC protocol driver has a number of configurable parameters that can be
adjusted through sysctls in /proc/net/rxrpc/:
(*) req_ack_delay
The amount of time in milliseconds after receiving a packet with the
request-ack flag set before we honour the flag and actually send the
requested ack.
Usually the other side won't stop sending packets until the advertised
reception window is full (to a maximum of 255 packets), so delaying the
ACK permits several packets to be ACK'd in one go.
(*) soft_ack_delay
The amount of time in milliseconds after receiving a new packet before we
generate a soft-ACK to tell the sender that it doesn't need to resend.
(*) idle_ack_delay
The amount of time in milliseconds after all the packets currently in the
received queue have been consumed before we generate a hard-ACK to tell
the sender it can free its buffers, assuming no other reason occurs that
we would send an ACK.
(*) resend_timeout
The amount of time in milliseconds after transmitting a packet before we
transmit it again, assuming no ACK is received from the receiver telling
us they got it.
(*) max_call_lifetime
The maximum amount of time in seconds that a call may be in progress
before we preemptively kill it.
(*) dead_call_expiry
The amount of time in seconds before we remove a dead call from the call
list. Dead calls are kept around for a little while for the purpose of
repeating ACK and ABORT packets.
(*) connection_expiry
The amount of time in seconds after a connection was last used before we
remove it from the connection list. Whilst a connection is in existence,
it serves as a placeholder for negotiated security; when it is deleted,
the security must be renegotiated.
(*) transport_expiry
The amount of time in seconds after a transport was last used before we
remove it from the transport list. Whilst a transport is in existence, it
serves to anchor the peer data and keeps the connection ID counter.
(*) rxrpc_rx_window_size
The size of the receive window in packets. This is the maximum number of
unconsumed received packets we're willing to hold in memory for any
particular call.
(*) rxrpc_rx_mtu
The maximum packet MTU size that we're willing to receive in bytes. This
indicates to the peer whether we're willing to accept jumbo packets.
(*) rxrpc_rx_jumbo_max
The maximum number of packets that we're willing to accept in a jumbo
packet. Non-terminal packets in a jumbo packet must contain a four byte
header plus exactly 1412 bytes of data. The terminal packet must contain
a four byte header plus any amount of data. In any event, a jumbo packet
may not exceed rxrpc_rx_mtu in size.

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.
- Driver should call skb_tx_timestamp() as close to passing sk_buff to hardware
as possible. skb_tx_timestamp() provides a software time stamp if requested
and hardware timestamping is not possible (SKBTX_IN_PROGRESS not set).
- 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

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 set the SKBTX_IN_PROGRESS flag (see above), then
dev_hard_start_xmit() checks whether software time stamping
is wanted as fallback and potentially generates the time stamp.
