2021-12-17ppc/pnv: Introduce a num_pecs class attribute for PHB4 PEC devicesCédric Le Goater1-0/+2
POWER9 processor comes with 3 PHB4 PEC (PCI Express Controller) and each PEC can have several PHBs : * PEC0 provides 1 PHB (PHB0) * PEC1 provides 2 PHBs (PHB1 and PHB2) * PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5) A num_pecs class attribute represents better the logic units of the POWER9 chip. Use that instead of num_phbs which fits POWER8 chips. This will ease adding support for user created devices.

2021-12-17softfloat: Add float64r32 arithmetic routinesRichard Henderson1-0/+12
These variants take a float64 as input, compute the result to infinite precision (as we do with FloatParts), round the result to the precision and dynamic range of float32, and then return the result in the format of float64. This is the operation PowerPC requires for its float32 operations.

2021-12-17glib-compat: Introduce g_memdup2() wrapperPhilippe Mathieu-Daudé1-0/+37
When experimenting raising GLIB_VERSION_MIN_REQUIRED to 2.68 (Fedora 34 provides GLib 2.68.1) we get: hw/virtio/virtio-crypto.c:245:24: error: 'g_memdup' is deprecated: Use 'g_memdup2' instead [-Werror,-Wdeprecated-declarations] ... g_memdup() has been updated by g_memdup2() to fix eventual security issues (size argument is 32-bit and could be truncated / wrapping). GLib recommends to copy their static inline version of g_memdup2(): https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538 Our glib-compat.h provides a comment explaining how to deal with these deprecated declarations (see commit e71e8cc0355 "glib: enforce the minimum required version and warn about old APIs"). Following this comment suggestion, implement the g_memdup2_qemu() wrapper to g_memdup2(), and use the safer equivalent inlined when we are using pre-2.68 GLib.

2021-12-15blockdev: Drop unused drive_get_next()Markus Armbruster1-1/+0
drive_get_next() is basically a bad idea. It returns the "next" block backend of a certain interface type. "Next" means bus=0,unit=N, where subsequent calls count N up from zero, per interface type. This lets you define unit numbers implicitly by execution order. If the order changes, or new calls appear "in the middle", unit numbers change. ABI break. Hard to spot in review. The previous commits eliminated all uses. Drop the function.

This makes it easier to have nested transactions where the top-level transactions pass objects to lower transactions that the latter can still use throughout their commit/abort phases, while the top-level transaction keeps a reference that is released in its .clean() method. (Before this commit, that is also possible, but the top-level transaction would need to take care to invoke tran_add() before the lower-level transaction does. This commit makes the ordering irrelevant, which is just a bit nicer.)

2021-11-15hw/intc/arm_gicv3: Support multiple redistributor regionsPeter Maydell1-1/+11
Our GICv3 QOM interface includes an array property redist-region-count which allows board models to specify that the registributor registers are not in a single contiguous range, but split into multiple pieces. We implemented this for KVM, but currently the TCG GICv3 model insists that there is only one region. You can see the limit being hit with a setup like: qemu-system-aarch64 -machine virt,gic-version=3 -smp 124 Add support for split regions to the TCG GICv3. To do this we switch from allocating a simple array of MemoryRegions to an array of GICv3RedistRegion structs so that we can use the GICv3RedistRegion as the opaque pointer in the MemoryRegion read/write callbacks. Each GICv3RedistRegion contains the MemoryRegion, a backpointer allowing the read/write callback to get hold of the GICv3State, and an index which allows us to calculate which CPU's redistributor is being accessed. Note that arm_gicv3_kvm always passes in NULL as the ops argument to gicv3_init_irqs_and_mmio(), so the only MemoryRegion read/write callbacks we need to update to handle this new scheme are the gicv3_redist_read/write functions used by the emulated GICv3.

2021-11-15hw/intc/arm_gicv3: Move checking of redist-region-count to ↵Peter Maydell1-1/+1
arm_gicv3_common_realize The GICv3 devices have an array property redist-region-count. Currently we check this for errors (bad values) in gicv3_init_irqs_and_mmio(), just before we use it. Move this error checking to the arm_gicv3_common_realize() function, where we sanity-check all of the other base-class properties. (This will always be before gicv3_init_irqs_and_mmio() is called, because that function is called in the subclass realize methods, after they have called the parent-class realize.) The motivation for this refactor is: * we would like to use the redist_region_count[] values in arm_gicv3_common_realize() in a subsequent patch, so we need to have already done the sanity-checking first * this removes the only use of the Error** argument to gicv3_init_irqs_and_mmio(), so we can remove some error-handling boilerplate Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

2021-11-10rcu: Introduce force_rcu notifierGreg Kurz1-0/+15
The drain_rcu_call() function can be blocked as long as an RCU reader stays in a read-side critical section. This is typically what happens when a TCG vCPU is executing a busy loop. It can deadlock the QEMU monitor as reported in https://gitlab.com/qemu-project/qemu/-/issues/650 . This can be avoided by allowing drain_rcu_call() to enforce an RCU grace period. Since each reader might need to do specific actions to end a read-side critical section, do it with notifiers. Prepare ground for this by adding a notifier list to the RCU reader struct and use it in wait_for_readers() if drain_rcu_call() is in progress. An API is added for readers to register their notifiers. This is largely based on a draft from Paolo Bonzini.

2021-11-10monitor: Fix find_device_state() for IDs containing slashesMarkus Armbruster1-0/+12
Recent commit 6952026120 "monitor: Tidy up find_device_state()" assumed the function's argument is "the device's ID or QOM path" (as documented for device_del). It's actually either an absolute QOM path, or a QOM path relative to /machine/peripheral/. Such a relative path is a device ID when it doesn't contain a slash. When it does, the function now always fails. Broke iotest 200, which uses relative path "vda/virtio-backend". It fails because object_resolve_path_component() resolves just one component, not a relative path. The obvious function to resolve relative paths is object_resolve_path(). It picks a parent automatically. Too much magic, we want to specify the parent. Create new object_resolve_path_at() for that, and use it in find_device_state().

2021-11-08docs: remove non-reference uses of single backticksJohn Snow1-3/+3
The single backtick markup in ReST is the "default role". Currently, Sphinx's default role is called "content". Sphinx suggests you can use the "Any" role instead to turn any single-backtick enclosed item into a cross-reference. This is useful for things like autodoc for Python docstrings, where it's often nicer to reference other types with `foo` instead of the more laborious :py:meth:`foo`. It's also useful in multi-domain cases to easily reference definitions from other Sphinx domains, such as referencing C code definitions from outside of kerneldoc comments. Before we do that, though, we'll need to turn all existing usages of the "content" role to inline verbatim markup wherever it does not correctly resolve into a cross-refernece by using double backticks instead.

When guest is running Linux/X11 with extended multiple displays mode enabled, the guest shares one scanout resource each time containing whole surface rather than sharing individual display output separately. This extended frame is properly splited and rendered on the corresponding scanout surfaces but not in case of blob-resource (zero copy). This code change lets the qemu split this one large surface data into multiple in case of blob-resource as well so that each sub frame then can be blitted properly to each scanout. v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and height v3: updating stub function of virtio_gpu_update_dmabuf to match the type Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Vivek Kasireddy <vivek.kasireddy@intel.com> Signed-off-by: Dongwon Kim <dongwon.kim@intel.com> Message-Id: <20211104065153.28897-5-dongwon.kim@intel.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2021-11-04plugins: try and make plugin_insn_append more ergonomicAlex Bennée2-4/+15
Currently we make the assumption that the guest frontend loads all op code bytes sequentially. This mostly holds up for regular fixed encodings but some architectures like s390x like to re-read the instruction which causes weirdness to occur. Rather than changing the frontends make the plugin API a little more ergonomic and able to handle the re-read case. Stuff will still get strange if we read ahead of the opcode but so far no front ends have done that and this patch asserts the case so we can catch it early if they do.
