2021-03-24m68k: add the virtio devices aliasesLaurent Vivier
Similarly to 5f629d943cb0 ("s390x: fix s390 virtio aliases"), define the virtio aliases. This allows to start machines with virtio devices without knowledge of the implementation type. For instance, we can use "-device virtio-scsi" on m68k, s390x or PC, and the device will be respectively "virtio-scsi-device", "virtio-scsi-ccw" or "virtio-scsi-pci". This already exists for s390x and -ccw interfaces, add them for m68k and MMIO (-device) interfaces.

2021-03-23memory: Add offset_in_region to flatview_cb argumentsPeter Maydell
The function flatview_for_each_range() calls a callback for each range in a FlatView. Currently the callback gets the start and length of the range and the MemoryRegion involved, but not the offset within the MemoryRegion. Add this to the callback's arguments; we're going to want it for a new use in the next commit.

2021-03-19qemu-options: New -compat to set policy for deprecated interfacesMarkus Armbruster
New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<input-policy> configures what to do when deprecated input is received. Input policy can be "accept" (accept silently), or "reject" (reject the request with an error). -compat deprecated-output=<out-policy> configures what to do when deprecated output is sent. Output policy can be "accept" (pass on unchanged), or "hide" (filter out the deprecated parts). Default is "accept". Policies other than "accept" are implemented later in this series. For now, -compat covers only syntactic aspects of QMP, i.e. stuff tagged with feature 'deprecated'. We may want to extend it to cover semantic aspects, CLI, and experimental features. Note that there is no good way for management application to detect presence of -compat: it's not visible output of query-qmp-schema or query-command-line-options. Tolerable, because it's meant for testing. If running with -compat fails, skip the test.

2021-03-19hw: Replace anti-social QOM type namesMarkus Armbruster
Several QOM type names contain ',': ARM,bitband-memory etraxfs,pic etraxfs,serial etraxfs,timer fsl,imx25 fsl,imx31 fsl,imx6 fsl,imx6ul fsl,imx7 grlib,ahbpnp grlib,apbpnp grlib,apbuart grlib,gptimer grlib,irqmp qemu,register SUNW,bpp SUNW,CS4231 SUNW,DBRI SUNW,DBRI.prom SUNW,fdtwo SUNW,sx SUNW,tcx xilinx,zynq_slcr xlnx,zynqmp xlnx,zynqmp-pmu-soc xlnx,zynq-xadc These are all device types. They can't be plugged with -device / device_add, except for xlnx,zynqmp-pmu-soc, and I doubt that one actually works. They *can* be used with -device / device_add to request help. Usability is poor, though: you have to double the comma, like this: $ qemu-system-x86_64 -device SUNW,,fdtwo,help Trap for the unwary. The fact that this was broken in device-introspect-test for more than six years until commit e27bd49876 fixed it demonstrates that "the unwary" includes seasoned developers. One QOM type name contains ' ': "ICH9 SMB". Because having to remember just one way to quote would be too easy. Rename the "SUNW,FOO types to "sun-FOO". Summarily replace ',' and ' ' by '-' in the other type names.

2021-03-19qom: move user_creatable_add_opts logic to vl.c and QAPIfy itPaolo Bonzini
Emulators are currently using OptsVisitor (via user_creatable_add_opts) to parse the -object command line option. This has one extra feature, compared to keyval, which is automatic conversion of integers to lists as well as support for lists as repeated options: -object memory-backend-ram,id=pc.ram,size=1048576000,host-nodes=0,policy=bind So we cannot replace OptsVisitor with keyval right now. Still, this patch moves the user_creatable_add_opts logic to vl.c since it is not needed anywhere else, and makes it go through user_creatable_add_qapi. In order to minimize code changes, the predicate still takes a string. This can be changed later to use the ObjectType QAPI enum directly.

2021-03-16fuzz: move some DMA hooksAlexander Bulekov
For the sparse-mem device, we want the fuzzer to populate entire DMA reads from sparse-mem, rather than hooking into the individual MMIO memory_region_dispatch_read operations. Otherwise, the fuzzer will treat each sequential read separately (and populate it with a separate pattern). Work around this by rearranging some DMA hooks. Since the fuzzer has it's own logic to skip accidentally writing to MMIO regions, we can call the DMA cb, outside the flatview_translate loop.

2021-03-15usb: Un-deprecate -usbdevice (except for -usbdevice audio which gets removed)Thomas Huth
When trying to remove the -usbdevice option, there were complaints that "-usbdevice braille" is still a very useful shortcut for some people. Thus we never remove this option. Since it's not such a big burden to keep it around, and it's also convenient in the sense that you don't have to worry to enable a host controller explicitly with this option, we should remove it from he deprecation list again. However, there is one exception: "-usbdevice audio" should go away, since audio devices without "audiodev=..." parameter are also on the deprecation list and you cannot use "-usbdevice audio" with "audiodev".

2021-03-12dma: Introduce dma_aligned_pow2_mask()Eric Auger
Currently get_naturally_aligned_size() is used by the intel iommu to compute the maximum invalidation range based on @size which is a power of 2 while being aligned with the @start address and less than the maximum range defined by @gaw. This helper is also useful for other iommu devices (virtio-iommu, SMMUv3) to make sure IOMMU UNMAP notifiers only are called with power of 2 range sizes. Let's move this latter into dma-helpers.c and rename it into dma_aligned_pow2_mask(). Also rewrite the helper so that it accomodates UINT64_MAX values for the size mask and max mask. It now returns a mask instead of a size. Change the caller.

2021-03-06trace: skip qemu_set_log_filename if no "-D" option was passedPaolo Bonzini
When the "simple" backend is not active but the "log" backend is, both "-trace file=" and "-D" will result in a call to qemu_set_log_filename. Unfortunately, QEMU was also calling qemu_set_log_filename if "-D" was not passed, so the "-trace file=" option had no effect and the tracepoints went back to stderr. Fortunately we can just skip qemu_set_log_filename in that case, because the log backend will initialize itself just fine as soon as qemu_set_log is called, also in qemu_process_early_options.

2021-03-06vl.c: do not execute trace_init_backends() before daemonizingDaniel Henrique Barboza
Commit v5.2.0-190-g0546c0609c ("vl: split various early command line options to a separate function") moved the trace backend init code to the qemu_process_early_options(). Which is now being called before os_daemonize() via qemu_maybe_daemonize(). Turns out that this change of order causes a problem when executing QEMU in daemon mode and with CONFIG_TRACE_SIMPLE. The trace thread is now being created by the parent, and the parent is left waiting for a trace file flush that was registered via st_init(). The result is that the parent process never exits. To reproduce, fire up a QEMU process with -daemonize and with CONFIG_TRACE_SIMPLE enabled. Two QEMU process will be left in the host: $ sudo ./x86_64-softmmu/qemu-system-x86_64 -S -no-user-config -nodefaults \ -nographic -machine none,accel=kvm:tcg -daemonize $ ps axf | grep qemu 529710 pts/3 S+ 0:00 | \_ grep --color=auto qemu 529697 ?

Libvirt waits for the parent process to exit to be sure that the QMP monitor is available in the daemonized process to fetch QEMU capabilities, and as is now Libvirt hangs at daemon start waiting for the parent thread to exit. The fix is simple: just move the trace backend related code back to be executed after daemonizing.

2021-02-16sev/i386: Don't allow a system reset under an SEV-ES guestTom Lendacky
An SEV-ES guest does not allow register state to be altered once it has been measured. When an SEV-ES guest issues a reboot command, Qemu will reset the vCPU state and resume the guest. This will cause failures under SEV-ES. Prevent that from occuring by introducing an arch-specific callback that returns a boolean indicating whether vCPUs are resettable.

2021-02-08cpu-throttle: Remove timer_mod() from cpu_throttle_set()Utkarsh Tripathi
During migrations, after each iteration, cpu_throttle_set() is called, which irrespective of input, re-arms the timer according to value of new_throttle_pct. This causes cpu_throttle_thread() to be delayed in getting scheduled and consqeuntly lets guest run for more time than what the throttle value should allow. This leads to spikes in guest throughput at high cpu-throttle percentage whenever cpu_throttle_set() is called. A solution would be not to modify the timer immediately in cpu_throttle_set(), instead, only modify throttle_percentage so that the throttle would automatically adjust to the required percentage when cpu_throttle_timer_tick() is invoked. Manually tested the patch using following configuration: Guest: Centos7 (3.10.0-123.el7.x86_64) Total Memory - 64GB , CPUs - 16 Tool used - stress (1.0.4) Workload - stress --vm 32 --vm-bytes 1G --vm-keep Migration Parameters: Network Bandwidth - 500MBPS cpu-throttle-initial - 99 Results: With timer_mod(): fails to converge, continues indefinitely Without timer_mod(): converges in 249 sec Signed-off-by: Utkarsh Tripathi <utkarsh.tripathi@nutanix.com> Message-Id: <1609420384-119407-1-git-send-email-utkarsh.tripathi@nutanix.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-02-08fuzz: ignore address_space_map is_write flagAlexander Bulekov
We passed an is_write flag to the fuzz_dma_read_cb function to differentiate between the mapped DMA regions that need to be populated with fuzzed data, and those that don't. We simply passed through the address_space_map is_write parameter. The goal was to cut down on unnecessarily populating mapped DMA regions, when they are not read from. Unfortunately, nothing precludes code from reading from regions mapped with is_write=true. For example, see: https://lists.gnu.org/archive/html/qemu-devel/2021-01/msg04729.html This patch removes the is_write parameter to fuzz_dma_read_cb. As a result, we will fill all mapped DMA regions with fuzzed data, ignoring the specified transfer direction.

2021-02-08confidential guest support: Introduce cgs "ready" flagDavid Gibson
The platform specific details of mechanisms for implementing confidential guest support may require setup at various points during initialization. Thus, it's not really feasible to have a single cgs initialization hook, but instead each mechanism needs its own initialization calls in arch or machine specific code. However, to make it harder to have a bug where a mechanism isn't properly initialized under some circumstances, we want to have a common place, late in boot, where we verify that cgs has been initialized if it was requested. This patch introduces a ready flag to the ConfidentialGuestSupport base type to accomplish this, which we verify in qemu_machine_creation_done().

we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.
