Journal

Week -4: [ Apr 18 - May 24 ] Debug hardware problem
Week -3: [ Apr 25 - May 2 ] Trace gPXE code base
Week -2: [ May 3 - May 9 ] Implement JMicron driver
Week -1: [ May 10 - May 16 ] Modify JMicron driver, RX offloading
Week 0: [ May 17 - May 23 ] TCP performance test and tunning
Week 1: [ May 24 - May 30 ] Update wiki, TCP tunning
Week 2: [ May 31 - Jun 6 ] Update jme driver, Trace memory related codes
Week 3 [ Jun 7 - Jun 13 ] Trace memory related codes, misc things
Week 4 to 7 [ Jun 14 - Jul 11 ] Studying for PhD qualifying exam.
Week 8:
- Several TCP fixes
Week 9:
- TCP cleanup
- Trace gPXE boot initialize steps about memory environment setup.
Week 10:
- Create a branch to merge latest iPXE TCP related commits based on gPXE master.
- Re-do my previous TCP patches against merged branch.
- Post the patches on the gpxe-devel and wait for feedback.
Week 11:
- Testing TCP performance with different window size, network environment.
- Port wscale branch against current gPXE master
Week 12:
- Port wscale branch against current gPXE master
- Continue testing TCP performance with different window size, network environment.
- Trace the issue that gPXE download speed slow on KVM.
Maybe after GSoC period
- Discuss the testing results and find a reasonable size.
- gPXE scheduling and program flow documentation.
- Possible more devel-docs.

TODO
- Gillies: 88E8055 PCI-E Gigabit Ethernet Controller [11ab:4363], after the “ifopen net0” I have the prompt back and it crashes (Keyboad is blocked, no message). If I am fast enough, I can type 2 or 3 letters on the new prompt before it's blocked.
- meteger: there are a few PCI IDs in the current tg3 that work fine when you do a tftp or HTTP transfer but fail miserably for iscsi, for some reason. but that driver was ported to etherboot in 2003, and it took 7 years for someone to request that specific PCI ID.
