2016-02-23include: Clean up includesPeter Maydell
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. NB: If this commit breaks compilation for your out-of-tree patchseries or fork, then you need to make sure you add #include "qemu/osdep.h" to any new .c files that you have.

2016-01-13isa: Clean up error handling around isa_bus_new()Markus Armbruster
We can have at most one ISA bus. If you try to create another one, isa_bus_new() complains to stderr and returns null. isa_bus_new() is called in two contexts, machine's init() and device's realize() methods. Since complaining to stderr is not proper in the latter context, convert isa_bus_new() to Error. Machine's init(): * mips_jazz_init(), called from the init() methods of machines "magnum" and "pica" * mips_r4k_init(), the init() method of machine "mips" * pc_init1() called from the init() methods of non-q35 PC machines * typhoon_init(), called from clipper_init(), the init() method of machine "clipper" These callers always create the first ISA bus, hence isa_bus_new() can't fail. Simply pass &error_abort. Device's realize(): * i82378_realize(), of PCI device "i82378" * ich9_lpc_realize(), of PCI device "ICH9-LPC" * pci_ebus_realize(), of PCI device "ebus" * piix3_realize(), of PCI device "pci-piix3", abstract parent of "PIIX3" and "PIIX3-xen" * piix4_realize(), of PCI device "PIIX4" * vt82c686b_realize(), of PCI device "VT82C686B" Propagate the error. Note that these devices are typically created only by machine init() methods with qdev_init_nofail() or similar. If we screwed up and created an ISA bus before that call, we now give up right away. Before, we'd hobble on, and typically die in isa_bus_irqs(). Similar if someone finds a way to hot-plug one of these critters. Cc: Richard Henderson <rth@twiddle.net> Cc: "Michael S.

2015-09-09i8257: remove cpu_request_exit irqPaolo Bonzini
This is unused. cpu_exit now is almost exclusively an internal function to the CPU execution loop. In a few patches, we'll change the remaining occurrences to qemu_cpu_kick, making it truly internal. Reviewed-by: Richard henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-09-09i8257: rewrite DMA_schedule to avoid hooking into the CPU loopPaolo Bonzini
The i8257 DMA controller uses an idle bottom half, which by default does not cause the main loop to exit. Therefore, the DMA_schedule function is there to ensure that the CPU relinquishes the iothread mutex to the iothread. However, this is not enough since the iothread will call aio_compute_timeout() and go to sleep again. In the iothread world, forcing execution of the idle bottom half is much simpler, and only requires a call to qemu_notify_event(). Do it, removing the need for the "cpu_request_exit" pseudo-irq. The next patch will remove it. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-01-26Add DSDT node for AppleSMCGabriel L. Somlo
AppleSMC (-device isa-applesmc) is required to boot OS X guests. OS X expects a SMC node to be present in the ACPI DSDT. This patch adds a SMC node to the DSDT, and dynamically patches the return value of SMC._STA to either 0x0B if the chip is present, or otherwise to 0x00, before booting the guest.

2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
