Week 1 ( May 23 - May 29 )
Day 1 ( May 23 )
- Compile linux kernel from top-of-git code
- Push (unmodified, as of yet) linux working tree to etherboot server
- Understanding how tg3 probe, open, PHY, etc functions work, read relevant parts of the datasheet
- Make minor modification to tg3.c, compile and load module to get used to the process of compiling/testing kernel modules
Day 2 ( May 24 )
- Todo: Add Journal for Day 2
Day 3 ( May 25 )
- More datasheet and code reading about descriptor ring handling, receive/transmit, offloading functions
- Completely unexpectedly discovered another tg3 test machine. I have 4 cards to test with now.
- Removed ethtool support functions. Tested on 2 machines. Reduces lines of code by almost 2000 lines. Yay.
- Started removing of checksum-offloading functions. Not yet pushed, as it's unfinished.
- Created new Driver-only Repository. Easier to pull than a full kernel tree.
Day 4 ( May 26 )
- Removed support for DMA addresses > 4GB
- Removed workarounds needed on some variants for DMA addresses > 4GB
- Removed power management functions
- Started removing dependency on kernel's phylib. Luckily I have a card variant that uses the phylib in normal operation.
- Brush up knowledge about memory barriers
