| - slb/pfe driver has frame work to verify on Chipit. |
| - This will generate .ko file to load. Verified for 3.0.2 Kernel version. |
| - This kernel module creates a few proc entries, to control pfe driver for unit test verification. |
| |
| Status: |
| ------- |
| - Chipit verification is not yet completed fully. |
| - FW loading and PFE init is verified. |
| - read class pe DMEM memory is good. |
| - Able to send packets from host (hif) to PFE. and Class PE receives the packets. |
| - hif tx descriptor chain traverse by TX BDP and TX DMA looks ok. |
| - The content of the packet loaded in PBUF is not completely good. Few locations are corrupted. Need investigation. |
| - Some times, class-pe hangs (lockups) observed. Need investigation. |
| - rx header contenet in the pbuf is good. (ddr address, pkt_len, phy_portno) |
| - class-pe to Host path not yet verified. |
| - GEMAC interaction not yet verified. |
| |
| Files: |
| ------ |
| Makefile.chipit - Makefile for PCI verification module (slb_pfe.ko) |
| Readme.chipit - This file |
| |
| pfe - pfe_lib directory |
| pfe.c - pfe_lib file |
| pfe_driver.c - pfe control driver |
| pfe_firmware.c - pfe fw loader |
| pfe_pci.c - pfe pci specific |
| pfe_proc.c - Handles proc interface for sbl_pfe driver |
| pfe_unit.c - Some unit testing function |
| |
| hal.h |
| pfe_driver.h |
| pfe_firmware.h |
| pfe_mod.h |
| |
| |
| To compile: |
| ----------- |
| $cp Makefile.chipit Makeifle |
| $make |
| |
| |
| To load: |
| -------- |
| $insmod sbl_pfe.ko |
| |
| |
| To verify: |
| ---------- |
| $cat /proc/pfe/pkt |
| ==> This will dump TX DMA status. |
| |
| $echo <pkt_len> > /proc/pfe/pkt |
| ==> this will send(tx) a packet from host to pfe. |
| |
| $cat /proc/pfe/dump |
| ==> This will dump 4 class-pe program counnters |
| |
| $echo <class_id> > /proc/pfe/dump |
| ==> this will dump PBUF[0] memory (256 bytes) of given class_id |
| |
| As the testing is processing... we can add more control as per the requirement. |
