| I did some cleanups in the code today. I also implemented tg3_close() and tg3_remove_one(). Those were the last two missing functions and implementing them resulted in a successful first boot of the driver :). | I did some cleanups in the code today.

| + | ====== Day 2 ( Aug 9 ) ====== | ||
| + | |||
| + | More cleanups. Removed most of the out-commented code that was left in the driver and some other simplifications. While going through the code I also compiled a list of suspicious looking things that I want to revisit the coming days. | ||
| + | |||
| + | ====== Day 3 ( Aug 10 ) ====== | ||
| + | |||
| + | Not much coding today, but a lot of testing. Tested the driver with all 4 test cards I have available, testing: | ||
| + | * Booting linux + initrd over HTTP and TFTP | ||
| + | * Booting linux over iSCSI | ||
| + | * Booting MSDOS over iSCSI, running scandisk on a 512MB iSCSI disk. | ||
| + | |||
| + | Interrupt support is not fully implemented yet, so UNDI chainloading tests were saved for later. Will see if I can get ahold of a Symantec Ghost DOS disk to stresstest the UNDI/interrupt support. | ||
| + | |||
| + | I was doing all that testing in Vienna and unfortunately forgot one test card there, so I only have 3 cards to test until the next time I get to Vienna(Probably next week). | ||
| + | |||
| + | ====== Day 4 ( Aug 11 ) ====== | ||
| + | |||
| + | I moved kicking off autoneg to tg3_init_one() from tg3_open(). This results in the BANNER_TIMEOUT being used for auto negotiation, which should save a few seconds boot time, as autoneg can take up to 6 seconds to complete. | ||
| + | struct tg3_napi was also removed and its fields merged into struct tg3. | ||
| + | |||
| + | ====== Day 5 ( Aug 12 ) ====== | ||
| + | |||
| + | Moved programming of the MAC address to tg3_open() instead of tg3_init_one(), as dictated by the gPXE API specifications. | ||
| + | Also removed was the NIC stats block, which saves some heap memory. | ||
| + | I also removed more leftover code. | ||
| + | |||
| + | ====== Day 7 ( Aug 14 ) ====== | ||
| + | |||
| + | A little interrupt related work. Completely untested and I still have to clear up some uncertainty on my side about tagged irq status, especially tp->last_tag. | ||
