I have a e100 card that needs a binary firmware blob loaded before it is usable: 00:0c.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 08) I don't really think that's the issue with QEMU, though.

After I made the DMA buffer cacheline-aligned, e1000 driver works well in VMWare. > > All code (DDE Linux26 and modified gnumach) is in the dde branch of incubator > and in master-user_level_drivers branch of the gnumach repository.

Mach provides the time in seconds and microseconds, but the Linux drivers need jiffies. DDE has to convert microseconds into jiffies so `jiffies' in the porting of DDE is defined as a macro instead of a variable. It sometimes causes some troubles because some Linux structures have a field named jiffies. Zheng Da

state updates on porting of dde linux26
Hello, I'm testing the porting of DDE Linux26 with different types of NIC drivers on VMWare and qemu. I tested pcnet32, ne2k-pci, rtl8139, e1000. pcnet32 works in both VMWare and qemu. Only qemu emulates ne2k-pci and rtl8139 cards and both DDE drivers work well in qemu. The odd thing occurs to e1000. VMWare and qemu both emulate e1000. DDE e1000 doesn't work in VMWare but work quite well in qemu. I don't know why. All code (DDE Linux26 and modified gnumach) is in the dde branch of incubator and in master-user_level_drivers branch of the gnumach repository. I appreciate if someone can help me test the drivers in a real machine or test other NIC drivers.
