2020-05-15hw: Remove unnecessary DEVICE() castPhilippe Mathieu-Daudé
The DEVICE() macro is defined as: #define DEVICE(obj) OBJECT_CHECK(DeviceState, (obj), TYPE_DEVICE) which expands to: ((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name), __FILE__, __LINE__, __func__)) This assertion can only fail when @obj points to something other than its stated type, i.e. when we're in undefined behavior country. Remove the unnecessary DEVICE() casts when we already know the pointer is of DeviceState type.

2019-12-18vga: cleanup mapping of VRAM for non-PCI VGAPaolo Bonzini
vga_init_vbe is now used only from ISA VGA cards. Since the alias is not needed anymore, remove it (effectively reverting commit 8294a64d7f, "vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29) and the now unused vbe_mapped field of VGACommonState. The function now consists of a single memory_region_add_subregion call, so we can inline it; this avoids incorrect usage from PCI cards.

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.

2019-08-16Include hw/hw.h exactly where neededMarkus Armbruster
In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

2018-07-03vga: disable global_vmstate for 3.0+ machine typesGerd Hoffmann
Move global_vmstate from vga_common_init() parameter to VGACommonState field. Set global_vmstate to true for isa vga devices, so nothing changes here. virtio-vga and secondary-vga already set global_vmstate to false so no change here either. All other pci vga devices get a new global-vmstate property, defaulting to false. A compat property flips it to true for older machine types. With this in place you don't get a vmstate section naming conflict any more when adding multiple pci vga devices to your vm.

2016-09-08portio: keep references on portioMarc-André Lureau
The isa_register_portio_list() function allocates ioports data/state. Let's keep the reference to this data on some owner. This isn't enough to fix leaks, but at least, ASAN stops complaining of direct leaks. Further cleanup would require calling portio_list_del/destroy().

2013-04-16console: simplify screendumpGerd Hoffmann
Screendumps are alot simpler as we can update non-active QemuConsoles now. So we only need to update the QemuConsole we want write out, then dump the DisplaySurface content into a ppm file. Done. No console switching needed. No special support code in the gfx card emulation needed. Zap it all. Also move ppm_save out of the vga code and next to the qmp_screendump function. For now screen dumping is limited to console #0 (like it used to be), even though it is dead simple to extend it to other consoles. I wanna finish the console cleanup before setting new qapi interfaces into stone. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Igor Mitsyanko <i.mitsyanko@gmail.com>
