2020-01-30stubs: add stubs for io_uring interfaceAarushi Mehta1-0/+1
Follow linux-aio.o and stub out the block/io_uring.o APIs that will be missing when a binary is linked with obj-util-y but without block-util-y (e.g. vhost-user-gpu). For example, the stubs are necessary so that a binary using util/async.o from obj-util-y for qemu_bh_new() links successfully. In this case block/io_uring.o from block-util-y isn't needed and we can avoid dragging in the block layer by linking the stubs instead. The stub functions never get called.

2019-10-14replay: add BH oneshot event for block layerPavel Dovgalyuk1-0/+1
Replay is capable of recording normal BH events, but sometimes there are single use callbacks scheduled with aio_bh_schedule_oneshot function. This patch enables recording and replaying such callbacks. Block layer uses these events for calling the completion function. Replaying these calls makes the execution deterministic.

2018-05-07pc-dimm: factor out MemoryDevice interfaceDavid Hildenbrand1-1/+1
On the qmp level, we already have the concept of memory devices: "query-memory-devices" Right now, we only support NVDIMM and PCDIMM. We want to map other devices later into the address space of the guest. Such device could e.g. be virtio devices. These devices will have a guest memory range assigned but won't be exposed via e.g. ACPI. We want to make them look like memory device, but not glued to pc-dimm. Especially, it will not always be possible to have TYPE_PC_DIMM as a parent class (e.g. virtio devices). Let's use an interface instead. As a first part, convert handling of - qmp_pc_dimm_device_list - get_plugged_memory_size to our new model. plug/unplug stuff etc. will follow later. A memory device will have to provide the following functions: - get_addr(): Necessary, as the property "addr" can e.g. not be used for virtio devices (already defined). - get_plugged_size(): The amount this device offers to the guest as of now. - get_region_size(): Because this can later on be bigger than the plugged size. - fill_device_info(): Fill MemoryDeviceInfo, e.g. for qmp.

2017-09-08hw/acpi: Move acpi_set_pci_info to pcihpAnthony PERARD1-0/+1
HW part of ACPI PCI hotplug in QEMU depends on ACPI_PCIHP_PROP_BSEL being set on a PCI bus that supports ACPI hotplug. It should work regardless of the source of ACPI tables (QEMU generator/legacy SeaBIOS/Xen). So move ACPI_PCIHP_PROP_BSEL initialization into HW ACPI implementation part from QEMU's ACPI table generator. To do PCI passthrough with Xen, the property ACPI_PCIHP_PROP_BSEL needs to be set, but this was done only when ACPI tables are built which is not needed for a Xen guest. The need for the property starts with commit "pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twice" (f0c9d64a68b776374ec4732424a3e27753ce37b6).

2015-11-12monitor/target-ppc: Define target_get_monitor_defAlexey Kardashevskiy1-0/+1
At the moment get_monitor_def() returns only registers from statically defined monitor_defs array. However there is a lot of BOOK3S SPRs which are not in the list and cannot be printed from the monitor. This adds a new target platform hook - target_get_monitor_def(). The hook is called if a register was not found in the static array returned by the target_monitor_defs() hook. The hook is only defined for POWERPC, it returns registered SPRs and fails on unregistered ones providing the user with information on what is actually supported on the running CPU. The register value is saved as uint64_t as it is the biggest supported register size; target_ulong cannot be used because of the stub - it is in a "common" code and cannot include "cpu.h", etc; this is also why the hook prototype is redefined in the stub instead of being included from some header. This replaces static descriptors for GPRs, FPRs, SRs with a helper which looks for a value in a corresponding array in the CPUPPCState. The immediate effect is that all 32 SRs can be printed now (instead of 16); later this can be reused for VSX or TM registers. This replaces callbacks for MSR and XER with static descriptors in monitor_defs as they are stored in CPUPPCState. While we are here, this adds "cr" as a synonym of "ccr".
