Is there any simple LS1043A DPAA reference driver other than Linux/U-Boot?

sempori — Sat, 01 Jan 2022 03:19:15 GMT

I am developing LS1043A Ethernet driver for a RTOS. I could check the communication on Independent Mode, and I want to add the QMAN and BMAN functionality now.

I referred U-Boot source for Independent Mode settings. But, since U-Boot does not support QMAN and BMAN, I have to refer some other source for these settings.

Is there any simple driver similar to U-Boot which I can refer to QMAN and BMAN initialization and settings? Is there any Application notes which describe more detailed on QMAN and BMAN settings?

Since Linux seems to be complex to me, I want to refer some other simple source. Kindly let me know.

There is no such simple driver.

QMAN and BMAN are described in the QorIQ LS1043A Data Path Acceleration Architecture (DPAA) Reference Manual.

If so, Kindly let me know which source files in Linux can I refer for the QMAN, BMAN and FMAN settings for LS1043ARDB board specific?

Kindly let me know is there any way to dump the registers values of BMan, QMan and FMan in Linux? I would like to check the register settings with my driver. It is extremely difficult to trace through the Linux code to know about the settings of them. Please help me.

There is no off-the-shelf tool to perform requested registers dumps.

You either have to implement it yourself or apply to the paid NXP Engineering Services:
