Where is Linux Driver for (PCIE + LLMAC_10GBASER) on Arria10 GX

Hello experts,

WE now  build an A10GX PCIE Card w/ 4 x 10GE. 

We need to implement  (PCIE3x8 + LLMAC_10GBASER) functions on this SmartNIC alike Card, and it's plugged into PC PCIe .  Now my question is: since we Host runs Linux OS, where can we find the appropriate linux driver for this card ?  is there any example as reference ? 

 

Best regards

Hi,


The driver/firmware of the FPGA system design usually needs to be done by the firmware designer, however, from the Arria 10 example design, it comes with either window or Linux driver, these drivers might not be able to use directly in the customs system design.


Window driver:

Thanks Reply from @SengKok_L_Intel

that AN829 driver only demostrate "PCIe AVMM DMA" part,but that's not enough for 10GE Ethenrnet Scenario.   The ethernet part driver needs to initiate and configure LLMAC group registers to make ethenet port running up, aslo the driver need check LLMAC Status or inteerupt register to be aware of any bidirectional packets and events/   I don't think AN829 have this functionality. 

 

Has not Intel provide this kind of  “10GE Linux Driver reference" code ?  At least I do't find any from Googling .   Thanks

Unfortunately, the 10G ethernet driver is NOT available.
