2013-11-05qdev: Drop misleading qdev_free() functionStefan Hajnoczi
The qdev_free() function name is misleading since all the function does is unlink the device from its parent. The device is not necessarily freed. The device will be freed when its QObject refcount reaches zero. It is usual for the parent (bus) to hold the final reference but there are cases where something else holds a reference so "free" is a misleading name. Call object_unparent(obj) directly instead of having a qdev wrapper function.

2013-10-31integrator: fix Linux boot failure by emulating dbg regionAlex Bennée
Commit 9b8c69243 (since reverted) broke the ability to boot the kernel as the value returned by unassigned_mem_read returned non-zero and left the kernel looping forever waiting for it to change (see integrator_led_set in the kernel code). Relying on a varying implementation detail is incorrect anyway so this introduces a basic stub of a memory region for the debug/LED section on the integrator board.

2013-10-29block: Avoid unecessary drv->bdrv_getlength() callsKevin Wolf
The block layer generally keeps the size of an image cached in bs->total_sectors so that it doesn't have to perform expensive operations to get the size whenever it needs it. This doesn't work however when using a backend that can change its size without qemu being aware of it, i.e. passthrough of removable media like CD-ROMs or floppy disks. For this reason, the caching is disabled when a removable device is used. It is obvious that checking whether the _guest_ device has removable media isn't the right thing to do when we want to know whether the size of the host backend can change. To make things worse, non-top-level BlockDriverStates never have any device attached, which makes qemu assume they are removable, so drv->bdrv_getlength() is always called on the protocol layer. In the case of raw-posix, this causes unnecessary lseek() system calls, which turned out to be rather expensive. This patch completely changes the logic and disables bs->total_sectors caching only for certain block driver types, for which a size change is expected: host_cdrom and host_floppy on POSIX, host_device on win32; also the raw format in case it sits on top of one of these protocols, but in the common case the nested bdrv_getlength() call on the protocol driver will use the cache again and avoid an expensive drv->bdrv_getlength() call.

2013-10-25spapr: Use DeviceClass::fw_name for device tree CPU nodeAndreas Färber
Instead of relying on cpu_model, obtain the device tree node label per CPU. Use DeviceClass::fw_name as source. Whenever DeviceClass::fw_name is unknown, default to "PowerPC,UNKNOWN". As a consequence, spapr_fixup_cpu_dt() can operate on each CPU's fw_name, obsoleting sPAPREnvironment::cpu_model, and spapr_create_fdt_skel() can drop its cpu_model argument.

Recent (host) kernels support emulating the PAPR defined "XICS" interrupt controller system within KVM. This patch allows qemu to initialize and configure the in-kernel XICS, and keep its state in sync with qemu's XICS state as necessary. This should give considerable performance improvements. e.g. on a simple IPI ping-pong test between hardware threads, using qemu XICS gives us around 5,000 irqs/second, whereas the in-kernel XICS gives us around 70,000 irqs/s on the same hardware configuration.

2013-10-25xics: split to xics and xics-commonAlexey Kardashevskiy
The upcoming XICS-KVM support will use bits of emulated XICS code. So this introduces new level of hierarchy - "xics-common" class. Both emulated XICS and XICS-KVM will inherit from it and override class callbacks when required. The new "xics-common" class implements: 1. replaces static "nr_irqs" and "nr_servers" properties with the dynamic ones and adds callbacks to be executed when properties are set. 2. xics_cpu_setup() callback renamed to xics_common_cpu_setup() as it is a common part for both XICS'es 3. xics_reset() renamed to xics_common_reset() for the same reason. The emulated XICS changes: 1. the part of xics_realize() which creates ICPs is moved to the "nr_servers" property callback as realize() is too late to create/initialize devices and instance_init() is too early to create devices as the number of child devices comes via the "nr_servers" property. 2. added ics_initfn() which does a little part of what xics_realize() did.

This emulates Win32 manual-reset events using futexes or conditional variables.

2013-10-14i386: ACPI table generation code from seabiosMichael S. Tsirkin
This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.
