Hi I'm curios what was that change & undo about in test12 and test13pre3ac3 regarding the disabling of PCI IO and MM access while writing to the config registers in pci_read_bases().
These lines were cut from test 12 and now they are back.
/* Disable IO and memory while we fiddle */ pci_read_config_word(dev, PCI_COMMAND, &cmd); tmp = cmd & ~(PCI_COMMAND_IO | PCI_COMMAND_MEMORY); pci_write_config_word(dev, PCI_COMMAND, tmp); [.....] pci_write_config_word(dev, PCI_COMMAND, cmd);
Why were they cut in the first place? Can anyone enlighten me?
Thanks, Jani.
