NDK, Packet Accelerator conflicting with SRIO driver

Brandy Jabkiewicz

hello,

Can someone please explain to me how the NDK uses the packet accelerator? I have read the Packet Accelerator documentation and I can see how ndk applications call and initialize the PA with its necessary firmware. However, what I don't see is how it is assigning queues and such.

I mean, what portion of the NDK configures the PA with the necessary calls that setup the engines and layers?

After I understand it better, I would also like to know if this could be causing conflicts with my SRIO driver? I did not change anything in the Packet Accelerator initialization code in my merge, but I thought maybe the SRIO driver uses the packet accelerator too? I saw an api about adding srio to the PA. Please explain this API and if I should use it.

Thanks,
Brandy

Brandy,

In the PDK directory, look for NIMU driver

“..\pdk_C6670_1_0_0_17\packages\ti\transport\ndk\nimu\src\nimu_eth.c’

“..\pdk_C6670_1_0_0_17\packages\ti\transport\ndk\nimu\include\nimu_internal.h’

Please let me know if you have further questions.

With regards to SRIO using PA, I will get you an answer soon.

Hi Varada,

Is there any way you can give me a more verbal explanation? Since this is a topic I am not too familar with, reading the code means I do alot of guessing.

Thanks,
Brandy

Brandy,

http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide#Network_Development_Kit_.28NDK.29 gives some primer information.

Also, one more thing the SRIO can configured to use the Packet acclerator. I will point you to a description/user guide in a bit.
