2020-01-24accel: Introduce the current_accel() wrapperPhilippe Mathieu-Daudé
The accel/ code only accesses the MachineState::accel field. As we simply want to access the accelerator, not the machine, add a current_accel() wrapper.

2019-12-17tcg: add "-accel tcg,tb-size" and deprecate "-tb-size"Paolo Bonzini
-tb-size fits nicely in the new framework for accelerator-specific options. It is a very niche option, so insta-deprecate it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-12-17accel: pass object to accel_init_machinePaolo Bonzini
We will have to set QOM properties before accel_init_machine, based on the options provided to -accel. Construct the object outside it so that it will be possible to iterate on properties between object_new_with_class and accel_init_machine.

2019-12-17vl: merge -accel processing into configure_acceleratorsPaolo Bonzini
The next step is to move the parsing of "-machine accel=..." into vl.c, unifying it with the configure_accelerators() function that has just been introduced. This way, we will be able to desugar it into multiple "-accel" options, without polluting accel/accel.c. The CONFIG_TCG and CONFIG_KVM symbols are not available in vl.c, but we can use accel_find instead to find their value at runtime. Once we know that the binary has one of TCG or KVM, the default accelerator can be expressed simply as "tcg:kvm", because TCG never fails to initialize.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

2019-07-19hmp: Print if memory section is registered with an acceleratorAlexey Kardashevskiy
This adds an accelerator name to the "into mtree -f" to tell the user if a particular memory section is registered with the accelerator; the primary user for this is KVM and such information is useful for debugging purposes. This adds a has_memory() callback to the accelerator class allowing any accelerator to have a label in that memory tree dump. Since memory sections are passed to memory listeners and get registered in accelerators (rather than memory regions), this only prints new labels for flatviews attached to the system address space. An example: Root memory region: system 0000000000000000-0000002fffffffff (prio 0, ram): /objects/mem0 kvm 0000003000000000-0000005fffffffff (prio 0, ram): /objects/mem1 kvm 0000200000000020-000020000000003f (prio 1, i/o): virtio-pci 0000200080000000-000020008000003f (prio 0, i/o): capabilities Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Message-Id: <20190614015237.82463-1-aik@ozlabs.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-06-07accel: Remove unused AccelClass::opt_name attributeWainer dos Santos Moschetta
The AccelType type was converted to AccelClass QOM object on b14a0b7469f, and the original data type had a field to store the option name which in turn was used to search an accelerator. The lookup method (accel_find) changed too, making the option field unnecessary but it became AccelClass::opt_name despite that. Therefore, and given that none accelerator implementation sets AccelClass::opt_name, let's remove this attribute.

2019-01-11accel: Improve selection of the default acceleratorThomas Huth
When compiling with "--disable-tcg", we currently still use "tcg" as default accelerator. "kvm" should be used in this case instead. Also, some downstream distros provide QEMU binaries which have "kvm" in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use KVM by default - and some users might want to do something similar with upstream binaries, too. Accomodate them by using "kvm:tcg" as default when we detect such a binary name.

2017-06-28accel: introduce AccelClass.global_propsPeter Xu
Introduce this new field for the accelerator classes so that each specific accelerator in the future can register its own global properties to be used further by the system. It works just like how the old machine compatible properties do, but only tailored for accelerators. Introduce register_compat_props_array() for it. Export it so that it may be used in other codes as well in the future.

Re-run scripts/clean-includes to apply the previous commit's corrections and updates. Besides redundant qemu/typedefs.h, this only finds a redundant config-host.h include in ui/egl-helpers.c. No idea how that escaped the previous runs. Some manual whitespace trimming around dropped includes squashed in.

2014-10-09accel: Pass MachineState object to accel init functionsEduardo Habkost
Most of the machine options and machine state information is in the MachineState object, not on the MachineClass. This will allow init functions to use the MachineState object directly instead of qemu_get_machine_opts() or the current_machine global.

2014-10-04accel: Rename 'init' method to 'init_machine'Eduardo Habkost
Today, all accelerator init functions affect some global state: * tcg_init() calls tcg_exec_init() and affects globals such as tcg_tcx, page size globals, and possibly others; * kvm_init() changes the kvm_state global, cpu_interrupt_handler, and possibly others; * xen_init() changes the xen_xc global, and registers a change state handler. With the new accelerator QOM classes, initialization may now be split in two steps: * instance_init() will do basic initialization that doesn't affect any global state and don't need MachineState or MachineClass data. This will allow probing code to safely create multiple accelerator objects on the fly just for reporting host/accelerator capabilities, for example. * accel_init_machine()/init_machine() will save the accelerator object in MachineState, and do initialization steps which still affect global state, machine state, or that need data from MachineClass or MachineState. To clarify the difference between those two steps, rename init() to init_machine(). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
