trace: Add trace-events file for declaring trace events This patch introduces the trace-events file where trace events can be declared like so: qemu_malloc(size_t size) "size %zu" qemu_free(void *ptr) "ptr %p" These trace event declarations are processed by a new tool called tracetool to generate code for the trace events. Trace event declarations are independent of the backend tracing system (LTTng User Space Tracing, ftrace markers, DTrace). The default "nop" backend generates empty trace event functions. Therefore trace events are disabled by default. The trace-events file serves two purposes: 1. Adding trace events is easy. It is not necessary to understand the details of a backend tracing system. The trace-events file is a single location where trace events can be declared without code duplication. 2. QEMU is not tightly coupled to one particular backend tracing system. In order to support tracing across QEMU host platforms and to anticipate new backend tracing systems that are currently maturing, it is important to be flexible and not tied to one system. This commit includes fixes from Prerna Saxena <prerna@linux.vnet.ibm.com> and Blue Swirl <blauwirbel@gmail.com>. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

# Trace events for debugging and performance instrumentation
#
# This file is processed by the tracetool script during the build.
#
# To add a new trace event:
#
# 1. Choose a name for the trace event. Declare its arguments and format
# string.
#
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
# trace_multiwrite_cb(). The source file must #include "trace.h".

trace: Support disabled events in trace-events Sometimes it is useful to disable a trace event. Removing the event from trace-events is not enough since source code will call the trace_*() function for the event. This patch makes it easy to build without specific trace events by marking them disabled in trace-events: disable multiwrite_cb(void *mcb, int ret) "mcb %p ret %d" This builds without the multiwrite_cb trace event. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> trace: Allow bulk enabling/disabling of trace events at compile time For 'simple' trace backend, allow bulk enabling/disabling of trace events at compile time. Trace events that are preceded by 'disable' keyword are compiled in, but turned off by default. These can individually be turned on using the monitor. All other trace events are enabled by default. TODO : This could be enhanced when the trace-event namespace is partitioned into a group and an ID within that group. In such a case, marking a group as enabled would automatically enable all trace-events listed under it.

aio: add generic thread-pool facility Add a generic thread-pool. The code is roughly based on posix-aio-compat.c, with some changes, especially the following: - use QemuSemaphore instead of QemuCond; - separate the state of the thread from the return code of the worker function. The return code is totally opaque for the thread pool; - do not busy wait when doing cancellation. A more generic threadpool (but still specific to I/O so that in the future it can use special scheduling classes or PI mutexes) can have many uses: it allows more flexibility in raw-posix.c and can more easily be extended to Win32, and it will also be used to do an msync of the persistent bitmap.

Add search path support for qemu data files. This patch allows to specify multiple directories where qemu should look for data files. To implement that the behavior of the -L switch is slightly different now: Instead of replacing the data directory the path specified will be appended to the data directory list. So when specifiying -L multiple times all directories specified will be checked, in the order they are specified on the command line, instead of just the last one. Additionally the default paths are always appended to the directory data list. This allows to specify a incomplete directory (such as the seabios out/ directory) via -L. Anything not found there will be loaded from the default paths, so you don't have to create a symlink farm for all the rom blobs. For trouble-shooting a tracepoint has been added, logging which blob has been loaded from which location.

trace: add qemu_system_powerdown_request and qemu_system_shutdown_request trace events We have the experience that the guest doesn't stop successfully though it was instructed to shut down. The root cause may be not in QEMU mostly. However, QEMU is often suspected at the beginning just because the issue occurred in virtualization environment. Therefore, we need to affirm that QEMU received the shutdown request and raised ACPI irq from "virsh shutdown" command, virt-manger or stopping QEMU process to the VM . So that we can affirm the problems was belonged to the Guset OS rather than the QEMU itself. When we stop guests by "virsh shutdown" command or virt-manger, or stopping QEMU process, qemu_system_powerdown_request() or qemu_system_shutdown_request() is called. Then the below functions in main_loop_should_exit() of Vl.c are called roughly in the following order. if (qemu_powerdown_requested()) qemu_system_powerdown() monitor_protocol_event(QEVENT_POWERDOWN, NULL) OR if(qemu_shutdown_requested()} monitor_protocol_event(QEVENT_SHUTDOWN, NULL); The tracepoint of monitor_protocol_event() already exists, but no tracepoints are defined for qemu_system_powerdown_request() and qemu_system_shutdown_request(). So this patch adds two tracepoints for the two functions. We believe that it will become much easier to isolate the problem mentioned above by these tracepoints.

Xen: Use the ioreq-server API when available The ioreq-server API added to Xen 4.5 offers better security than the existing Xen/QEMU interface because the shared pages that are used to pass emulation request/results back and forth are removed from the guest's memory space before any requests are serviced. This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is.

xen: Introduce the Xen mapcache On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory. Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the lock option, so mapcache will not unmap these ram_ptr. Blocks that do not belong to the RAM, but usually to a device ROM or to a framebuffer, are handled in a separate function. So the whole RAMBlock can be map.

coroutine: introduce coroutines Asynchronous code is becoming very complex. At the same time synchronous code is growing because it is convenient to write. Sometimes duplicate code paths are even added, one synchronous and the other asynchronous. This patch introduces coroutines which allow code that looks synchronous but is asynchronous under the covers. A coroutine has its own stack and is therefore able to preserve state across blocking operations, which traditionally require callback functions and manual marshalling of parameters. Creating and starting a coroutine is easy: coroutine = qemu_coroutine_create(my_coroutine); qemu_coroutine_enter(coroutine, my_data); The coroutine then executes until it returns or yields: void coroutine_fn my_coroutine(void *opaque) { MyData *my_data = opaque; /* do some work */ qemu_coroutine_yield(); /* do some more work */ } Yielding switches control back to the caller of qemu_coroutine_enter(). This is typically used to switch back to the main thread's event loop after issuing an asynchronous I/O request. The request callback will then invoke qemu_coroutine_enter() once more to switch back to the coroutine. Note that if coroutines are used only from threads which hold the global mutex they will never execute concurrently. This makes programming with coroutines easier than with threads. Race conditions cannot occur since only one coroutine may be active at any time. Other coroutines can only run across yield. This coroutines implementation is based on the gtk-vnc implementation written by Anthony Liguori <anthony@codemonkey.ws> but it has been significantly rewritten by Kevin Wolf <kwolf@redhat.com> to use setjmp()/longjmp() instead of the more expensive swapcontext() and by Paolo Bonzini <pbonzini@redhat.com> for Windows Fibers support.

# qemu-coroutine-lock.c
coroutine: stop using AioContext in CoQueue qemu_co_queue_next(&queue) arranges that the next queued coroutine is run at a later point in time. This deferred restart is useful because the caller may not want to transfer control yet. This behavior was implemented using QEMUBH in the past, which meant that CoQueue (and hence CoMutex and CoRwlock) had a dependency on the AioContext event loop. This hidden dependency causes trouble when we move to a world with multiple event loops - now qemu_co_queue_next() needs to know which event loop to schedule the QEMUBH in. After pondering how to stash AioContext I realized the best solution is to not use AioContext at all. This patch implements the deferred restart behavior purely in terms of coroutines and no longer uses QEMUBH. Here is how it works: Each Coroutine has a wakeup queue that starts out empty. When qemu_co_queue_next() is called, the next coroutine is added to our wakeup queue. The wakeup queue is processed when we yield or terminate. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

hw/9pfs: Introduce tracing for 9p pdu handlers Plan is to replace the existing debug infrastructure with Qemu tracing infrastructure so that user can dynamically enable/disable trace events and therefore a meaningful trace log can be generated which can be further filtered using an analysis script. Note: Because of current simpletrace limitations, the trace events are logging at max 6 args, however, once the more args are supported, we can change trace events to log more info as well.

hw: Convert from BlockDriverState to BlockBackend, mostly Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member.

In that case there is no need to create a new pixman image pointing to the same backing storage. We can just use the existing image directly. This does not only simplify things a bit, but most importantly it gets the reference counting right, so the backing storage for the pixman image wouldn't be released underneath us. Use new function in virtio-gpu, where using it actually fixes use-after-free crashes.

spapr_pci: Use XICS interrupt allocator and do not cache interrupts in PHB Currently SPAPR PHB keeps track of all allocated MSI (here and below MSI stands for both MSI and MSIX) interrupt because XICS used to be unable to reuse interrupts. This is a problem for dynamic MSI reconfiguration which happens when guest reloads a driver or performs PCI hotplug. Another problem is that the existing implementation can enable MSI on 32 devices maximum (SPAPR_MSIX_MAX_DEVS=32) and there is no good reason for that. This makes use of new XICS ability to reuse interrupts. This reorganizes MSI information storage in sPAPRPHBState. Instead of static array of 32 descriptors (one per a PCI function), this patch adds a GHashTable when @config_addr is a key and (first_irq, num) pair is a value. GHashTable can dynamically grow and shrink so the initial limit of 32 devices is gone. This changes migration stream as @msi_table was a static array while new @msi_devs is a dynamic hash table. This adds temporary array which is used for migration, it is populated in "spapr_pci"::pre_save() callback and expanded into the hash table in post_load() callback. Since the destination side does not know the number of MSI-enabled devices in advance and cannot pre-allocate the temporary array to receive migration state, this makes use of new VMSTATE_STRUCT_VARRAY_ALLOC macro which allocates the array automatically. This resets the MSI configuration space when interrupts are released by the ibm,change-msi RTAS call. This fixed traces to be more informative. This changes vmstate_spapr_pci_msi name from "...lsi" to "...msi" which was incorrect by accident. As the internal representation changed, thus bumps migration version number.

spapr: Add ibm, client-architecture-support call The PAPR+ specification defines a ibm,client-architecture-support (CAS) RTAS call which purpose is to provide a negotiation mechanism for the guest and the hypervisor to work out the best compatibility parameters. During the negotiation process, the guest provides an array of various options and capabilities which it supports, the hypervisor adjusts the device tree and (optionally) reboots the guest. At the moment the Linux guest calls CAS method at early boot so SLOF gets called. SLOF allocates a memory buffer for the device tree changes and calls a custom KVMPPC_H_CAS hypercall. QEMU parses the options, composes a diff for the device tree, copies it to the buffer provided by SLOF and returns to SLOF. SLOF updates the device tree and returns control to the guest kernel. Only then the Linux guest parses the device tree so it is possible to avoid unnecessary reboot in most cases. The device tree diff is a header with an update format version (defined as 1 in this patch) followed by a device tree with the properties which require update. If QEMU detects that it has to reboot the guest, it silently does so as the guest expects reboot to happen because this is usual pHyp firmware behavior. This defines custom KVMPPC_H_CAS hypercall. The current SLOF already has support for it. This implements stub which returns very basic tree (root node, no properties) to the guest. As the return buffer does not contain any change, no change in behavior is expected. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>

spapr: Implement processor compatibility in ibm, client-architecture-support Modern Linux kernels support last POWERPC CPUs so when a kernel boots, in most cases it can find a matching cpu_spec in the kernel's cpu_specs list. However if the kernel is quite old, it may be missing a definition of the actual CPU. To provide an ability for old kernels to work on modern hardware, a Processor Compatibility Mode has been introduced by the PowerISA specification. >From the hardware prospective, it is supported by the Processor Compatibility Register (PCR) which is defined in PowerISA. The register enables one of the compatibility modes (2.05/2.06/2.07). Since PCR is a hypervisor privileged register and cannot be directly accessed from the guest, the mode selection is done via ibm,client-architecture-support (CAS) RTAS call using which the guest specifies what "raw" and "architected" CPU versions it supports. QEMU works out the best match, changes a "cpu-version" property of every CPU and notifies the guest about the change by setting these properties in the buffer passed as a response on a custom H_CAS hypercall. This implements ibm,client-architecture-support parameters parsing (now only for PVRs) and cooks the device tree diff with new values for "cpu-version", "ibm,ppc-interrupt-server#s" and "ibm,ppc-interrupt-server#s" properties.

spapr_iommu: Move table allocation to helpers At the moment presence of vfio-pci devices on a bus affect the way the guest view table is allocated. If there is no vfio-pci on a PHB and the host kernel supports KVM acceleration of H_PUT_TCE, a table is allocated in KVM. However, if there is vfio-pci and we do yet not KVM acceleration for these, the table has to be allocated by the userspace. At the moment the table is allocated once at boot time but next patches will reallocate it. This moves kvmppc_create_spapr_tce/g_malloc0 and their counterparts to helpers.

spapr: Add support for time base offset migration This allows guests to have a different timebase origin from the host. This is needed for migration, where a guest can migrate from one host to another and the two hosts might have a different timebase origin. However, the timebase seen by the guest must not go backwards, and should go forwards only by a small amount corresponding to the time taken for the migration. This is only supported for recent POWER hardware which has the TBU40 (timebase upper 40 bits) register. That includes POWER6, 7, 8 but not 970. This adds kvm_access_one_reg() to access a special register which is not in env->spr. This requires kvm_set_one_reg/kvm_get_one_reg patch. The feature must be present in the host kernel. This bumps vmstate_spapr::version_id and enables new vmstate_ppc_timebase only for it. Since the vmstate_spapr::minimum_version_id remains unchanged, migration from older QEMU is supported but without vmstate_ppc_timebase.

tcg: Clean up from 'next_tb' The value returned from tcg_qemu_tb_exec() is the value passed to the corresponding tcg_gen_exit_tb() at translation time of the last TB attempted to execute. It is a little confusing to store it in a variable named 'next_tb'. In fact, it is a combination of 4-byte aligned pointer and additional information in its two least significant bits. Break it down right away into two variables named 'last_tb' and 'tb_exit' which are a pointer to the last TB attempted to execute and the TB exit reason, correspondingly. This simplifies the code and improves its readability. Correct a misleading documentation comment for tcg_qemu_tb_exec() and fix logging in cpu_tb_exec(). Also rename a misleading 'next_tb' in another couple of places.

vfio_msix_enable(const char *name) " (%s)"
vfio/pci: Lazy PBA emulation The PCI spec recommends devices use additional alignment for MSI-X data structures to allow software to map them to separate processor pages. One advantage of doing this is that we can emulate those data structures without a significant performance impact to the operation of the device. Some devices fail to implement that suggestion and assigned device performance suffers. One such case of this is a Mellanox MT27500 series, ConnectX-3 VF, where the MSI-X vector table and PBA are aligned on separate 4K pages. If PBA emulation is enabled, performance suffers. It's not clear how much value we get from PBA emulation, but the solution here is to only lazily enable the emulated PBA when a masked MSI-X vector fires. We then attempt to more aggresively disable the PBA memory region any time a vector is unmasked. The expectation is then that a typical VM will run entirely with PBA emulation disabled, and only when used is that emulation re-enabled.

Generalize this to a set of common helpers in the core that pulls the region info from vfio, fills the region data, configures slow mapping, and adds helpers for comleting the mmap, enable/disable, and teardown. This can be immediately used by the PCI MSI-X code, which needs to mmap around the MSI-X vector table. This also changes VFIORegion.mem to be dynamically allocated because otherwise we don't know how the caller has allocated VFIORegion and therefore don't know whether to unreference it to destroy the MemoryRegion or not.

vfio/pci: Add emulated PCI IDs Specifying an emulated PCI vendor/device ID can be useful for testing various quirk paths, even though the behavior and functionality of the device with bogus IDs is fully unsupportable. We need to use a uint32_t for the vendor/device IDs, even though the registers themselves are only 16-bit in order to be able to determine whether the value is valid and user set. The same support is added for subsystem vendor/device ID, though these have the possibility of being useful and supported for more than a testing tool. An emulated platform might want to impose their own subsystem IDs or at least hide the physical subsystem ID. Windows guests will often reinstall drivers due to a change in subsystem IDs, something that VM users may want to avoid. Of course careful attention would be required to ensure that guest drivers do not rely on the subsystem ID as a basis for device driver quirks. All of these options are added using the standard experimental option prefix and should not be considered stable. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

vfio/pci: Intel graphics legacy mode assignment Enable quirks to support SandyBridge and newer IGD devices as primary VM graphics. This requires new vfio-pci device specific regions added in kernel v4.6 to expose the IGD OpRegion, the shadow ROM, and config space access to the PCI host bridge and LPC/ISA bridge. VM firmware support, SeaBIOS only so far, is also required for reserving memory regions for IGD specific use. In order to enable this mode, IGD must be assigned to the VM at PCI bus address 00:02.0, it must have a ROM, it must be able to enable VGA, it must have or be able to create on its own an LPC/ISA bridge of the proper type at PCI bus address 00:1f.0 (sorry, not compatible with Q35 yet), and it must have the above noted vfio-pci kernel features and BIOS. The intention is that to enable this mode, a user simply needs to assign 00:02.0 from the host to 00:02.0 in the VM: -device vfio-pci,host=0000:00:02.0,bus=pci.0,addr=02.0 and everything either happens automatically or it doesn't. In the case that it doesn't, we leave error reports, but assume the device will operate in universal passthrough mode (UPT), which doesn't require any of this, but has a much more narrow window of supported devices, supported use cases, and supported guest drivers. When using IGD in this mode, the VM firmware is required to reserve some VM RAM for the OpRegion (on the order or several 4k pages) and stolen memory for the GTT (up to 8MB for the latest GPUs). An additional option, x-igd-gms allows the user to specify some amount of additional memory (value is number of 32MB chunks up to 512MB) that is pre-allocated for graphics use. TBH, I don't know of anything that requires this or makes use of this memory, which is why we don't allocate any by default, but the specification suggests this is not actually a valid combination, so the option exists as a workaround. Please report if it's actually necessary in some environment. See code comments for further discussion about the actual operation of the quirks necessary to assign these devices.

If supported, enable cmma during kvm initialization and register a reset handler for cmma, which is also called directly from the load IPL code. The reset functionality is needed to reset the cmma state of the guest pages, e.g. if a system reset is triggered via qemu monitor; otherwise this could result in data corruption. A guest triggered reboot may now lead to multiple cmma resets; this is OK, however, as this is slowpath anyway and the simplest way to achieve the intended effects.

s390x/kvm: proper use of the cpu states OPERATING and STOPPED This patch makes sure that halting a cpu and stopping a cpu are two different things. Stopping a cpu will also set the cpu halted - this is needed for common infrastructure to work (note that the stop and stopped flag cannot be used for our purpose because they are already used by other mechanisms). A cpu can be halted ("waiting") when it is operating. If interrupts are disabled, this is called a "disabled wait", as it can't be woken up anymore. A stopped cpu is treated like a "disabled wait" cpu, but in order to prepare for a proper cpu state synchronization with the kvm part, we need to track the real logical state of a cpu.

crypto: introduce new base module for TLS credentials Introduce a QCryptoTLSCreds class to act as the base class for storing TLS credentials. This will be later subclassed to provide handling of anonymous and x509 credential types. The subclasses will be user creatable objects, so instances can be created & deleted via 'object-add' and 'object-del' QMP commands respectively, or via the -object command line arg. If the credentials cannot be initialized an error will be reported as a QMP reply, or on stderr respectively. The idea is to make it possible to represent and manage TLS credentials independently of the network service that is using them. This will enable multiple services to use the same set of credentials and minimize code duplication. A later patch will convert the current VNC server TLS code over to use this object. The representation of credentials will be functionally equivalent to that currently implemented in the VNC server with one exception. The new code has the ability to (optionally) load a pre-generated set of diffie-hellman parameters, if the file dh-params.pem exists, whereas the current VNC server will always generate them on startup. This is beneficial for admins who wish to avoid the (small) time sink of generating DH parameters at startup and/or avoid depleting entropy. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

io: add QIOTask class for async operations A number of I/O operations need to be performed asynchronously to avoid blocking the main loop. The caller of such APIs need to provide a callback to be invoked on completion/error and need access to the error, if any. The small QIOTask provides a simple framework for dealing with such probes. The API docs inline provide an outline of how this is to be used. Some functions don't have the ability to run asynchronously (eg getaddrinfo always blocks), so to facilitate their use, the task class provides a mechanism to run a blocking function in a thread, while triggering the completion callback in the main event loop thread. This easily allows any synchronous function to be made asynchronous, albeit at the cost of spawning a thread. In this series, the QIOTask class will be used for things like the TLS handshake, the websockets handshake and TCP connect() progress. The concept of QIOTask is inspired by the GAsyncResult interface / GTask class in the GIO libraries. The min version requirements on glib don't allow those to be used from QEMU, so QIOTask provides a facsimilie which can be easily switched to GTask in the future if the min version is increased.

### Guest events, keep at bottom
# @vaddr: Access' virtual address.
# @info : Access' information (see below).
#
# Start virtual memory access (before any potential access violation).
#
# Does not include memory accesses performed by devices.
#
# Access information can be parsed as:
#
# struct mem_info {
# uint8_t size_shift : 2; /* interpreted as "1 << size_shift" bytes */
# bool sign_extend: 1; /* sign-extended */
# uint8_t endianness : 1; /* 0: little, 1: big */
# bool store : 1; /* wheter it's a store operation */
# };
