Switch Abstraction Interface Implementation

sai's Issues

/usr/bin/ld: cannot find -lopennsl

Hey :)
Im trying to build this Broadcom SAI implementation on switch on top of Open Network Linux right now, and build fails on point where it tries to find opennsl library
Since in readme info its mentioned that in order to build that stuff i will need OpenNSL, i downloaded it as well, found prebuilt version suitable for me, which contains couple kernel module files and one .so file, which is name libopennsl.so. Is it the one needed to build SAI or not? Cause I dont see any others
I tried to do it hard way, just renaming libopennsl into opennsl but still got same build failure
So which library do i actually need and where do i get it?

Thx in advance

How can i get libsaibcm_X.X.X.X_amd64.deb? or how can i make libsaibcm_X.X.X.X_amd64.deb?

in sonic-buildimage\platform\broadcom, there are sai.mk, SONiC will use the .deb. How can i get libsaibcm_X.X.X.X_amd64.deb? or how can i make libsaibcm_X.X.X.X_amd64.deb?

Broadcom Tomahawk2 chip support sai deb package

Hello,

I am Balaselvi, working for Inventec.
Can you please let us know when can we get the sai deb package that supports Tomahawk2 board for SONiC?
If it is not official release to SONiC even an intermediate package is good.
Thank you.

Thanks and regards,
Bala

Supported protocol list

HI,

Can anyone kindly tell me , which protocols are supported by Broadcom SAI enables switches?
Also, is it possible to define new protocol header field(like P4) through this?

Port breakout with BCM56960 Tomahawk

I consulted SONiC if Tomahawk supports 2x50G or 4x25G breakout, and their answer is no as BRCM SAI does not support it. See here.

When will that feature be supported?

Trident 2+ BCM56864 Support

Dear Sirs,

Can you please confirm that the Broadcom (SAI) Switch Abstraction layer supports the Trident 2+ BCM56864.

I've tried to use SONiC and the SAI support does not appear to be working.

I've looked and can see this chipset is support in OpenNSL so I’m hopeful it is supported.

Thanks,

BROADCOM SAI CHIP support list unclear?

we have a swith with bcm56340 helix4, met coredump questions on SAI, we want to know if SAI 3.7 still support bcm56340 now ?

Building the kernel drivers for SAI

Hi,

I want to use a more modern kernel than the bundled 3.16 kernel. In OpenNSL I can simply build the .ko files for the kernel I want - does the same apply for SAI?

The release notes for the latest SAI release says it is using OpenNSL 3.4.1.11 but only v3.4.1.6 was released publicly as far as I can tell. Will the same kernel drivers work?

Support for BCM88470

Hello Team,
Can you please help me know about the extent of support for BCM88470 chipset.
I see that qumran is listed in (https://github.com/Azure/SONiC/wiki/Supported-Devices-and-Platforms) wanted confirmation and extent of support.
Can you also please point me to the procedure to access source code - Only headers seems to be available on master branch.
Thanks,
Bhuvan

Any roadmap to support Dune line of Chips?

We see over past release, support for XGS line of Chips getting added. Would you folks plan to add support for Dune line of Chips as well in this process. Anytime timeline related details would be helpful.

ARM32 or ARM64 for Broadcom BCM56864 Trident II+?

I'm new to SONiC and in the middle of going through the image build. I'm up to the part where I can select ARM32 or ARM64. I'm trying to find documentation on Broadcom's site as well. Does anyone if this truly matters in term of whether or not it will work properly?

Total number of logical ports allowed in libsai is 120?

Hello,
I am Balaselvi.
I using broadcom libsai version 0.9.4 and we are configuring SONiC for our board.
If I configure logical ports lesser than 120, things work perfectly fine, I can test traffic.
If I use logical ports more than 120, I face a crash in the libsai during switch initialization.

Can you guide me whether the maximum logical port setting is an issue, or I can change it with any configuration?
I checked the Opennsl "Customizing OpenNSL Platform" but i can't resolve this issue with any settings.

I feel this is a issue with libsai or libopennsl.
Any pointers or suggestion will really help me.

Thank you.

Thanks and regards,

Build Error with no package.cfg file

Hi,

I am trying to build SAI with OpenNSL SDK for Dell switch, but there is no package.cfg file for build. Error message is as follow:
Makefile:19: package.cfg: No such file or directory

How can I solve this problem?

Thanks~

TH/TH2/TD/TD2 port led issue

Hi

For TH/TH2/TD/TD2 port led, the port status register has 2 bit for port speed:
[4:3] Speed 00=10 Mbps, 01=100 Mbps, 10=1000 Mbps

But for 10G/25G/40G/50G/100G port, different port led need be lighted for different port speed. Then the register bits aren't enough.

I have two proposals for this issue.

1. The SAI provides a new API, the API will encapsulate soc_pci_wirte/read function, then the port speed information can be sent to the RAM field of port led. When the port led is lighted, it can get the port speed information.

2. Apply a patch in SDK process, SDK will send the port speed information to RAM of port led, Then the port can distinguish the different port speed in port led light. the patch as the attachment.

Can you help to check which is better? then integrate the related change to SAI or SDK.

Thanks,
Bo

What I found with SONiC SAI

Hi,

I am working on SONiC for a couple of months and encountered a few issues.

With SAI v1.0, there is error with function brcm_sai_create_switch() as below:

With SAI v0.94, there are 2 errors as below:

1. Error from function translate_rid_to_vid() -

   There is no issue with 40G port fan-out to be 4 10G ports.

I am not sure if these are SAI lib issues or it's due to the platform BCM56854_A2 I have is not supported. For any info related will be helpful. Thanks!

Will SAI ever be native?

Will Broadcom SAI implementation ever be built with native SDK API? or it is forever tied with OpenNSL?
