Am I wrong or is:
pci_enable_busmaster(dev);
pci_enable_io(dev, SYS_RES_IOPORT);
pci_enable_io(dev, SYS_RES_MEMORY);
(which I additionally added now) equivalent to (the allready existing):
data = pci_read_config(dev, PCIR_COMMAND, 2);
data |= (PCIM_CMD_PORTEN | PCIM_CMD_MEMEN | PCIM_CMD_BUSMASTEREN);
pci_write_config(dev, PCIR_COMMAND, data, 2);
anyway neither one seems to do the job.
bus_alloc_resource() still fails...
Any tips to analyse/debug the problem?
Bye!
