We can drop a device from the build only when it isn't referenced from
|
|
|
9ae3a8 |
code we build. References come in two forms: extern symbols, and qdev
|
|
|
9ae3a8 |
driver names.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Unresolved extern symbols pose no real danger, because they fail
|
|
|
9ae3a8 |
safely at link time. But the dropped code doesn't define any extern
|
|
|
9ae3a8 |
symbols anyway.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Unresolved driver names get detected only at runtime, so we better be
|
|
|
9ae3a8 |
extra careful. The only occurences of the driver name outside the
|
|
|
9ae3a8 |
code dropped by this patch is in machine type compat properties
|
|
|
9ae3a8 |
(safe), and those aren't even compiled for RHEL (extra safe).
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Since there's no CONFIG_IVSHMEM, we need to hack the Makefile
|
|
|
9ae3a8 |
directly. Creating CONFIG_IVSHMEM upstream would be nice, but we're
|
|
|
9ae3a8 |
out of time.
