Abstract
The aim of this project is to completely rewrite two legacy etherboot drivers present in iPXE: for VIA Rhine (VT6105M) and VIA Velocity (VT6122/VT6130) chipsets.
Deliverables
| Deliverable | Week | Current status |
|---|---|---|
| Investigate iPXE drivers API and PCI API | 1 | in progress |
| Write skeleton for new VIA Rhine driver: probe and attach card, read EEPROM, communicate with MII PHY | 2, 3 | in progress |
| Write send and receive (polling) support for VIA Rhine | 4, 5 | not done |
| Do functional and performance tests on driver | 6 | not done |
| Write skeleton for VIA Velocity driver: probe, attach, read EEPROM and PHY | 7, 8 | not done |
| Write send and receive support for VIA Velocity | 9, 10 | not done |
| Do functional and performance tests on driver | 11 | not done |
| Review the code and do final cleanup | 12 | not done |
| Commit code and write documentation | 13 | not done |
Daily progress
- 2012.05.20: Write skeleton for VIA Rhine driver based on skeleton.[ch]. Chip reset, MII read/write and reading MAC address from chip is working.
- 2012.05.22: Code style cleanup, introduce rhine_reload_eeprom() function to reload EEPROM contents. Working on link status notifications.
Test plan
- Functional tests: transferring images, link state and speed changes
- Performance tests: transfer speed
