We can drop a device from the build only when it isn't referenced from
|
|
|
218e99 |
code we build. References come in two forms: extern symbols, and qdev
|
|
|
218e99 |
driver names.
|
|
|
218e99 |
|
|
|
218e99 |
Unresolved extern symbols pose no real danger, because they fail
|
|
|
218e99 |
safely at link time. The dropped code doesn't define any extern
|
|
|
218e99 |
symbols anyway.
|
|
|
218e99 |
|
|
|
218e99 |
Unresolved driver names get detected only at runtime, so we better be
|
|
|
218e99 |
extra careful. Occurences of the driver name outside the code dropped
|
|
|
218e99 |
by this patch:
|
|
|
218e99 |
|
|
|
218e99 |
* default_list[] in vl.c: Used only to disable default VGA with
|
|
|
218e99 |
-device isa-vga. Safe.
|
|
|
218e99 |
|
|
|
218e99 |
* vga_available() in vl.c: Tests whether the device is compiled in.
|
|
|
218e99 |
No change, because device "VGA" is still compiled in, therfore safe.
|
|
|
218e99 |
|
|
|
218e99 |
* isa_vga_init() in hw/isa/isa-bus.c: Its only potential caller
|
|
|
218e99 |
pc_vga_init() never calls in RHEL, because it never gets a null
|
|
|
218e99 |
pci_bus argument. Safe.
