[Qemu-devel] [PATCH v4 17/33] pc: Eliminate all *_machine_options() functions |
Date: |
Thu, 14 Aug 2014 16:25:46 -0300 |
Finally eliminate all *_machine_options() functions, and make the
class_init functions for older machine-types simply reuse the class_init
functions from newer machine-types.
To allow compat_props reuse, the the PC_COMPAT_* macros were changed to
not nest within the older PC_COMPAT_* macros anymore.
We can now make all pc-{i440fx,q36}-* class_init functions call the previous
one.
For reference (to help ensure the reuse of previous class_init functions
won't change any behavior), these are the fields that are touched by the
class_init functions:
* name: All machine-types set it, class_init reuse won't affect it.
* hw_version: All machines older than pc*-1.0 already set it, class_init reuse
won't affect it.
* desc: Only the base pc-{i440fx,q35} classes set it, so all classes already
reused it.
* hot_add_cpu:
* The base pc-{i440fx,q35} classes set it (so it was already reused by all
subclasses).
* pc-i440fx-1.4 was already overriding it inside
pc_i440fx_1_4_machine_options() (and all older machine-types already
reused it).
* On pc_q35.c, only pc-q-35-1.4 (which is the oldest pc-q35 subclass) set it.
* alias: Only pc*-2.1 was setting it, pc*-2.0 was now changed to unset
it, so only pc*-2.1 still have it set.
* is_default: Only pc-i440fx-2.1 was setting it, pc-i440fx-2.0 was now
changed to unset it, so only pc-i440fx-2.1 still have it set.
* init: pc*-1.3 to pc*-2.1 were already setting it. The only ones that didn't
set it were using the one set by previous *machine_options() functions.
* compat_props: All machine-types used PC_COMPAT_* macros that reused the
previous one. Now they will simply append to the compat_props list added by
the previous class_init function, and PC_COMPAT_* won't include the previous
macros inside them.
* default_machine_opts: It was set by pc_*_2_1_machine_options() and is
now set by pc-*-2.1 class_init(). pc*-1.7 and older didn't reuse
pc_*_2_1_machine_options(), so now pc*-1.7 class_init() set
default_machine_opts to NULL to ensure pc-*1.7 and older don't inherit
it.
