2020-09-09Move QOM typedefs and add missing includesEduardo Habkost
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2019-08-16Include hw/irq.h a lot lessMarkus Armbruster
In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.

2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2018-10-15vfio/platform: Make the vfio-platform device non-abstractEric Auger
Up to now the vfio-platform device has been abstract and could not be instantiated. The integration of a new vfio platform device required creating a dummy derived device which only set the compatible string. Following the few vfio-platform device integrations we have seen the actual requested adaptation happens on device tree node creation (sysbus-fdt). Hence remove the abstract setting, and read the list of compatible values from sysfs if not set by a derived device. Update the amd-xgbe and calxeda-xgmac drivers to fill in the number of compatible values, as there can now be more than one. Note that sysbus-fdt does not support the instantiation of the vfio-platform device yet.

2015-10-05hw/vfio/platform: change interrupt/unmask fields into pointerEric Auger

2015-07-06hw/vfio/platform: add irqfd supportEric Auger
This patch aims at optimizing IRQ handling using irqfd framework. Instead of handling the eventfds on user-side they are handled on kernel side using - the KVM irqfd framework, - the VFIO driver virqfd framework. the virtual IRQ completion is trapped at interrupt controller This removes the need for fast/slow path swap. Overall this brings significant performance improvements.
