This patchset add Hisilicon Network Subsystem support. The subsystem
provides a long term developing network accelerate engine with ring buffer
interface. The network interface can be used as standard ethernet network
interface card or be made use by a network application with decoded L2 to
L4 data.
The patchset is porting from some internal-use drivers, it is tested and
working fine with the hardware. But some detail design is not that good.
But we want to know if the community can accept the structure/arch before
refining it. Thank you.

This patchset add Hisilicon Network Subsystem support. The subsystem
provides a long term developing network accelerate engine with ring buffer
interface. The network interface can be used as standard ethernet network
interface card or be made use by a network application with decoded L2 to
L4 data.
The patchset is porting from some internal-use drivers, it is tested and
working fine with the hardware. But some detail design is not that good.
But we want to know if the community can accept the structure/arch before
refining it. Thank you.

Cc: Kenneth Lee
The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoC. The IP, which is called hns for
short, is a TCP/IP acceleration engine, which can directly decode TCP/IP
stream and distribute them to different ring buffers.
HNS can be configured to work on different mode for different scenario.
This patch make use only some of the mode to make it as standard ethernet
NIC. The other mode will be added soon.
The whole function has 4 kernel sub-modules:
hnae: the HNS acceleration engine framework. It provides a abstract
interface between the engine and the upper layers which make use of the
engine by ring buffer.
hns_enet_drv: a standard ethernet driver that base on the ring buffer.
hns_dsaf: one of the implementation of HNS acceleration engine, which is
applied on Hililicon P660, Hi1610 and other later-on SoCs
hns_mdio: the mdio control to the PHY, used by acceleration engine
This submit add basic config and documents

* [PATCH 1/5] net: add Hisilicon Network Subsystem support (config and documents)
@ 2015-08-14 10:30 ` Kenneth Lee
0 siblings, 0 replies; 48+ messages in thread
From: Kenneth Lee @ 2015-08-14 10:30 UTC (permalink / raw)
To: linux-arm-kernel
The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoC. The IP, which is called hns for
short, is a TCP/IP acceleration engine, which can directly decode TCP/IP
stream and distribute them to different ring buffers.
HNS can be configured to work on different mode for different scenario.
This patch make use only some of the mode to make it as standard ethernet
NIC. The other mode will be added soon.
The whole function has 4 kernel sub-modules:
hnae: the HNS acceleration engine framework. It provides a abstract
interface between the engine and the upper layers which make use of the
engine by ring buffer.
hns_enet_drv: a standard ethernet driver that base on the ring buffer.
hns_dsaf: one of the implementation of HNS acceleration engine, which is
applied on Hililicon P660, Hi1610 and other later-on SoCs
hns_mdio: the mdio control to the PHY, used by acceleration engine
This submit add basic config and documents

HNAE (Hisilicon Network Acceleration Engine) is a framework to provide a
unified ring buffer interface for Hisilicon Network Acceleration Engines.
With the interface, upper layer can work as ethernet driver, ODP driver or
other service driver on purpose.

From: Kenneth Lee @ 2015-08-14 10:30 UTC (permalink / raw)
To: linux-arm-kernel
HNAE (Hisilicon Network Acceleration Engine) is a framework to provide a
unified ring buffer interface for Hisilicon Network Acceleration Engines.
With the interface, upper layer can work as ethernet driver, ODP driver or
other service driver on purpose.

Cc: Kenneth Lee
DSAF, namely Distributed System Area Fabric, is one of the HNS
acceleration engine implementation. This patch add DSAF driver to the
system.
hns_ae_adapt: the adaptor for registering the driver to HNAE framework
hns_dsaf_mac: MAC cover interface for GE and XGE
hns_dsaf_gmac: GE (10/100/1000G Ethernet) MAC function
hns_dsaf_xgmac: XGE (10000+G Ethernet) MAC function
hns_dsaf_main: the platform device driver for the whole hardware
hns_dsaf_misc: some misc helper function, such as LED support
hns_dsaf_ppe: packet process engine function
hns_dsaf_rcb: ring buffer function

Cc: Kenneth Lee
This is to add basic ethernet support for HNS. It is one of the way to use
the HNS acceleration engine. But most of the decoding/encoding capability
of the AE cannot be used in this way.
This submit contains the basic feature as a ethernet driver. More will be
added later.

Cc: Kenneth Lee
This is to add basic ethernet support for HNS. It is one of the way to use
the HNS acceleration engine. But most of the decoding/encoding capability
of the AE cannot be used in this way.
This submit contains the basic feature as a ethernet driver. More will be
added later.

* [PATCH 5/5] net: add Hisilicon Network Subsystem basic ethernet support

From: Kenneth Lee @ 2015-08-14 10:30 UTC (permalink / raw)
To: linux-arm-kernel
This is to add basic ethernet support for HNS. It is one of the way to use
the HNS acceleration engine. But most of the decoding/encoding capability
of the AE cannot be used in this way.
This submit contains the basic feature as a ethernet driver. More will be
added later.

These properties look very unconventional. What are the valid strings
for ae-name and ae-opts? It looks like the latter is just a number,
so why not use an integer property?

These look suspiciously similar to definitions from
drivers/net/ethernet/hisilicon/hip04_mdio.c.
Could the hardware be related? If so, please try to share
the common parts.

Something seems wrong here: why do you have an ACCESS_ONCE() on a
local variable? Doesn't this just make the code less efficient
without providing lockless access to shared variables?
The types are inconsistent here, you should get a warning from
running this through 'make C=1' because of the missing __iomem
annotation of the pointer.
Also, why both a macro and an inline function? Just use an inline
function.

Thanks, Arnd.
Regarding the ae-name: it is the name of the Acceleration Engine. It is provided by the BIOS according to the position and the feature enabled of the IP. So "soc0" means it is on SoC No. 0, while "n4" means it is running on "Non-dsaf mode 4". Ideally, we should setup the rule to name it. But as I said in the patchset, the IP is original designed for a bare metal solution, it is worthless to export all modes and we are planning to add more mode for Linux itself in the IP in future version. So I think the better way is to leave it as a "name" but add more meaning in the future.
Regarding the ae-opts: it is the initial value for the AE's runtime options, Currently, we have only "port number" (there are 6XGE+2GE port for a DSAF AE) as option. But for future version, we will add other options such as "enable Spanning Tree Protocol algorithm)" and so on.
Should I add these background to somewhere?
Best Regards

These properties look very unconventional. What are the valid strings
for ae-name and ae-opts? It looks like the latter is just a number,
so why not use an integer property?

Thanks, Arnd.
Regarding the ae-name: it is the name of the Acceleration Engine. It is provided by the BIOS according to the position and the feature enabled of the IP. So "soc0" means it is on SoC No. 0, while "n4" means it is running on "Non-dsaf mode 4". Ideally, we should setup the rule to name it. But as I said in the patchset, the IP is original designed for a bare metal solution, it is worthless to export all modes and we are planning to add more mode for Linux itself in the IP in future version. So I think the better way is to leave it as a "name" but add more meaning in the future.
Regarding the ae-opts: it is the initial value for the AE's runtime options, Currently, we have only "port number" (there are 6XGE+2GE port for a DSAF AE) as option. But for future version, we will add other options such as "enable Spanning Tree Protocol algorithm)" and so on.
Should I add these background to somewhere?
Best Regards
-Kenneth Lee (Hisilicon)

You are right. This is the same IP as hip04_mdio.c. We just mis-understand the
hardware design. We will merge them and re-submit the patches.

Do not declare functions 'inline' in foo.c files, let the compiler decide
on it's own.

Most entries of class_find_device() in kernel that i see perform
if-check for NULL on return value.
What do you think about such option for example:
return dev ? cls_to_ae_dev(dev) : NULL;
?
Is it possible that, someday, your dev will be NULL and creep in
container_of() that doesn't protected from ptr = NULL
and .... (let's go down a little in another function)

.. and here you might not receive NULL after container_of() works on
that returned NULL after class_find_device().
I guess that might happen after someone change order of fields in
struct hnae_ae_dev.
I understand that it's unlikely to happen but could you please check or comment?

Most entries of class_find_device() in kernel that i see perform
if-check for NULL on return value.
What do you think about such option for example:
return dev ? cls_to_ae_dev(dev) : NULL;
?
Is it possible that, someday, your dev will be NULL and creep in
container_of() that doesn't protected from ptr = NULL
and .... (let's go down a little in another function)

.. and here you might not receive NULL after container_of() works on
that returned NULL after class_find_device().
I guess that might happen after someone change order of fields in
struct hnae_ae_dev.
I understand that it's unlikely to happen but could you please check or comment?

Most entries of class_find_device() in kernel that i see perform
if-check for NULL on return value.
What do you think about such option for example:
return dev ? cls_to_ae_dev(dev) : NULL;
?
Is it possible that, someday, your dev will be NULL and creep in
container_of() that doesn't protected from ptr = NULL
and .... (let's go down a little in another function)

.. and here you might not receive NULL after container_of() works on
that returned NULL after class_find_device().
I guess that might happen after someone change order of fields in
struct hnae_ae_dev.
I understand that it's unlikely to happen but could you please check or comment?

The name property is a bit awkward. The position is normally implied by
the location of the parent device in the DT, so you should not need that
at all and instead derive it elsewhere. You can also add strings to the
compatible property instead of this, to signify differences in the programming
that are based on how the IP block is used.

I think these can easily be converted into an index property and boolean
flags (present if true, absent otherwise) for additional features.

The binding document needs to list all supported configurations, if you
have a string property, describe specifically what strings are allowed
and what they mean, but better try to avoid strings altogether.

Dear Arnd,
We are working on the new PatchSet. I describe the new design here so in case
you can tell us if we make something wrong.
So now we will keep some attributes in enthernet node like this:
ethernet@0{
compatible = "hisilicon,hns-nic";
ae-name = "dsaf1";
port-id = <0>;
};
ae-name is simply a name referring to the name of dsa_name in SAF node.
port-id is the index of port provided by DSAF (the accelerator). DSAF can
connect to 8 PHYs. Port 0 to 1 are both used for adminstration purpose. They
are called debug ports.
The remaining 6 PHYs are taken according to the mode of DSAF.
In NIC mode of DSAF, all 6 PHYs are taken as ethernet ports to the CPU. The
port-id can be 2 to 7. Here is the diagram:
+-----+---------------+
| CPU |
+-+-+-+---+-+-+-+-+-+-+
| | | | | | | |
debug service
port port
(0,1) (2-7)
In Switch mode of DSAF, all 6 PHYs are taken as physical ports connect to a
LAN Switch while the CPU side assume itself have one single NIC connect to
this switch. In this case, the port-id will be 2 only.
+-----+---------------+
| CPU |
+-+-+-+---+-+-+-+-+-+-+

ae-name is simply a name referring to the name of dsa_name in SAF node.
