2019-08-16Include migration/vmstate.h lessMarkus Armbruster
In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 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 VMStateDescription. The previous commit made that unnecessary. Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

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.

2018-01-25pl110: Implement vertical compare/next base interruptsLinus Walleij
This implements rudimentary support for interrupt generation on the PL110. I am working on a new DRI/KMS driver for Linux and since that uses the blanking interrupt, we need something to fire here. Without any interrupt support Linux waits for a while and then gives ugly messages about the vblank not working in the console (it does not hang perpetually or anything though, DRI is pretty forgiving). I solved it for now by setting up a timer to fire at 60Hz and pull the interrupts for "vertical compare" and "next memory base" at this interval. This works fine and fires roughly the same number of IRQs on QEMU as on the hardware and leaves the console clean and nice. People who want to create more accurate emulation can probably work on top of this if need be. It is certainly closer to the hardware behaviour than what we have today anyway.

2015-07-24framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebufferPaolo Bonzini
The MemoryRegionSection contains enough information to access the RAM region underlying the framebuffer, and can be cached inside the display device. By doing this, the new framebuffer_update_memory_section function can enable dirty memory logging on the relevant RAM region. The function must be called whenever the stride or base of the framebuffer changes; a simple way to cover these cases is to call it on every full frame invalidation, which is a rare case. framebuffer_update_display now works entirely on a MemoryRegionSection, without going through cpu_physical_memory_map/unmap.

2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

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>
