2018-01-09ebus: wire up OBIO interrupts to APB pbm via qdev GPIOsMark Cave-Ayland1-1/+7
This enables us to remove the static array mapping in the ISA IRQ handler (and the embedded reference to the APB device) by formalising the interrupt wiring via the qdev GPIO API. For more clarity we replace the APB OBIO interrupt numbers with constants designating the interrupt source, and rename isa_irq_handler() to ebus_isa_irq_handler().

2018-01-09apb: remove busA property from PBMPCIBridge stateMark Cave-Ayland1-3/+0
Since the previous commit the only remaining use of the qdev busA property is to configure the PCI bridge in front of the onboard ebus devices differently to allow early OpenBIOS serial console access. Instead we can now manually update the PCI configuration for bridge A in pci_pbm_reset() and thus completely remove the busA property from the PBMPCIBridge state.

This finally allows us to instantiate the APB directly using standard qdev create/init functions in sun4u.c.

2017-12-22block: Allow graph changes in subtree drained sectionKevin Wolf2-2/+5
We need to remember how many of the drain sections in which a node is were recursive (i.e. subtree drain rather than node drain), so that they can be correctly applied when children are added or removed during the drained section. With this change, it is safe to modify the graph even inside a bdrv_subtree_drained_begin/end() section. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-12-22block: Add bdrv_subtree_drained_begin/end()Kevin Wolf1-0/+13
bdrv_drained_begin() waits for the completion of requests in the whole subtree, but it only actually keeps its immediate bs parameter quiesced until bdrv_drained_end(). Add a version that keeps the whole subtree drained. As of this commit, graph changes cannot be allowed during a subtree drained section, but this will be fixed soon.

2017-12-22block: Don't notify parents in drain call chainKevin Wolf1-2/+2
This is in preparation for subtree drains, i.e. drained sections that affect not only a single node, but recursively all child nodes, too. Calling the parent callbacks for drain is pointless when we just came from that parent node recursively and leads to multiple increases of bs->quiesce_counter in a single drain call. Don't do it. In order for this to work correctly, the parent callback must be called for every bdrv_drain_begin/end() call, not only for the outermost one: If we have a node N with two parents A and B, recursive draining of A should cause the quiesce_counter of B to increase because its child N is drained independently of B. If now B is recursively drained, too, A must increase its quiesce_counter because N is drained independently of A only now, even if N is going from quiesce_counter 1 to 2.

2017-12-22i386: hvf: add code base from Google's QEMU repositorySergio Andres Gomez Del Real3-0/+105
This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

Since the commit, the qemu_chr_be_event() failed to deliver CHR_EVENT_BREAK due to qemu_chr_fe_init() does not set s->be in case of mux.

IOThread: while (!atomic_read(&iothread->stopping)) -> stopping=false 2. Main loop: iothread->stopping = true; aio_notify(iothread->ctx); 3. IOThread: aio_poll(iothread->ctx, true); -> hang The bug is explained by the AioContext->notify_me doc comments: "If this field is 0, everything (file descriptors, bottom halves, timers) will be re-evaluated before the next blocking poll(), thus the event_notifier_set call can be skipped." The problem is that "everything" does not include checking iothread->stopping. This means iothread_run() will block in aio_poll() if aio_notify() was called just before aio_poll(). This patch fixes the hang by replacing aio_notify() with aio_bh_schedule_oneshot(). This makes aio_poll() or g_main_loop_run() to return. Implementing this properly required a new bool running flag. The new flag prevents races that are tricky if we try to use iothread->stopping. Now iothread->stopping is purely for iothread_stop() and iothread->running is purely for the iothread_run() thread.

2017-12-19hw/block: Fix the return typeMao Zhongyi1-2/+2
When the function no success value to transmit, it usually make the function return void. It has turned out not to be a success, because it means that the extra local_err variable and error_propagate() will be needed. It leads to cumbersome code, therefore, transmit success/ failure in the return value is worth. So fix the return type of blkconf_apply_backend_options(), blkconf_geometry() and virtio_blk_data_plane_create() to avoid it.

2017-12-19coroutine: simplify co_aio_sleep_ns() prototypeStefan Hajnoczi1-5/+1
The AioContext pointer argument to co_aio_sleep_ns() is only used for the sleep timer. It does not affect where the caller coroutine is resumed. Due to changes to coroutine and AIO APIs it is now possible to drop the AioContext pointer argument. This is safe to do since no caller has specific requirements for which AioContext the timer must run in. This patch drops the AioContext pointer argument and renames the function to simplify the API.
