We can't drop it, because the ISA device is entangled with the PCI
|
|
|
9ae3a8 |
device, which we want to keep. Disentangling it upstream would be
|
|
|
9ae3a8 |
nice, but we're out of time.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Instead, make it unavailable with -device / device_add. Suffices,
|
|
|
9ae3a8 |
because the only other way to get it is via pc_vga_init() calling
|
|
|
9ae3a8 |
isa_vga_init(), which it never does in RHEL, because it never gets a
|
|
|
9ae3a8 |
null pci_bus argument.
