2013-01-28cpu: Unconditionalize CPUState fieldsAndreas Färber1-2/+0
Commits fc8c5b8c41ee5ba69d7a2be63b02a08c7b0b155b (Makefile.user: Define CONFIG_USER_ONLY for libuser/) and dd83b06ae61cfa2dc4381ab49f365bd0995fc930 (qom: Introduce CPU class) specifically prepared the qom/cpu.c file to be compiled differently for softmmu and *-user. This broke as part of build system refactorings while CPU patches were in flight, adding conditional fields kvm_fd (8737c51c0444f832c4e97d7eb7540eae457e08e4) and kvm_vcpu_dirty (20d695a9254c1b086a456d3b79a3c311236643ba) for softmmu. linux-user and bsd-user would therefore get a CPUState type with instance_size ~8 bytes longer than expected. Fix this by unconditionally having the fields in CPUState. In practice, target-specific CPU types' instance_size would compensate this, and upstream qom/cpu.c does not yet touch any affected field.

2013-01-27qom: Introduce object_class_is_abstract()Andreas Färber1-0/+8
This lets a caller check if an ObjectClass as returned by, e.g., object_class_by_name() is instantiatable. Signed-off-by: Andreas Färber <afaerber@suse.de> Cc: Anthony Liguori <anthony@codemonkey.ws>
2013-01-27cpu: Add model resolution support to CPUClassAndreas Färber1-0/+15
Introduce CPUClass::class_by_name and add a default implementation. Hook up the alpha and ppc implementations. Introduce a wrapper function cpu_class_by_name(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-17qom: Extend documentation on QOM method conceptsAndreas Färber1-3/+101
Add a documentation section "Methods" and discuss among others how to handle overriding virtual methods. Clarify DeviceClass::realize documentation and refer to the above. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-01-15Merge remote-tracking branch 'stefanha/trivial-patches' into stagingAnthony Liguori1-1/+1
* stefanha/trivial-patches: configure: try pkg-config for curses qom: Make object_resolve_path_component() path argument const Add libcacard/trace/generated-tracers.c to .gitignore Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-01-15qom: Make object_resolve_path_component() path argument constAndreas Färber1-1/+1
A usage with a hardcoded partial path such as object_resolve_path_component(obj, "foo") is totally valid but currently leads to a compilation error. Fix this. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-01-15exec: Return CPUState from qemu_get_cpu()Andreas Färber1-0/+10
Move the declaration to qemu/cpu.h and add documentation. The implementation still depends on CPUArchState for CPU iteration. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber1-0/+2
Note that target-alpha accesses this field from TCG, now using a negative offset. Therefore the field is placed last in CPUState. Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change. Move common parts of mips cpu_state_reset() to mips_cpu_reset(). Acked-by: Richard Henderson <rth@twiddle.net> (for alpha) [AF: Rebased onto ppc CPU subclasses and openpic changes] Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-01-15cpu: Move nr_{cores,threads} fields to CPUStateAndreas Färber1-0/+5
To facilitate the field movements, pass MIPSCPU to malta_mips_config(); avoid that for mips_cpu_map_tc() since callers only access MIPS Thread Contexts, inside TCG helpers. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-10Make all static TypeInfos constAndreas Färber1-3/+3
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-08cpu: Change parent type to DeviceEduardo Habkost1-3/+3
This finally makes the CPU class a subclass of the Device class, allowing us to start using DeviceState properties on CPU subclasses. It has no_user=1, as creating CPUs using -device doesn't work yet.
