Hi, We are having problem booting through gPXE with our UNDI drivers and we debugged this issue further and found that gPXE always expecting the underlying hardware to generate interrupts whenever it receives a packet from network. In our case as we are running in polling mode and our hardware has not been programmed to generate interrupts. In this situations how can we make gPXE work with our UNDI drivers?
Is there any reason that gPXE always expects interrupts to be enabled by underlying hardware? In my opinion can gPXE first find out whether device supports interrupts or not by looking at the bit 12 in "Serviceflags" field in PXEENV_UNDI_GET_IFACE_INFO (opcode=0x13) API and accordingly act on that? If this bit is set then that means device supports interrupts otherwise device does not support interrupts and upper layer protocol drivers should not hook interrupts. Any ideas or advise is greatly appreciated. -Muralidhar
