* include/hw/vfio/vfio-container.h: rename VFIOContainer to VFIOLegacyContainerMark Cave-Ayland2025-09-252-8/+9
| | | | | | | | | | | | The VFIOContainer struct represents the legacy VFIO container even though the name suggests it may be the common superclass of all VFIO containers. Rename it to VFIOLegacyContainer to make this clearer, which is also a better match for its VFIO_IOMMU_LEGACY QOM type name.

* include/hw/core/cpu: Invert the indexing into CPUTLBDescFastRichard Henderson2025-09-231-1/+10
| | | | | | | | | | | | | | | | This array is within CPUNegativeOffsetState, which means the last element of the array has an offset from env with the smallest magnitude. This can be encoded into fewer bits when generating TCG fast path memory references. When we changed the NB_MMU_MODES to be a global constant, rather than a per-target value, we pessimized the code generated for targets which use only a few mmu indexes. By inverting the array index, we counteract that.

| * 9pfs: Add FreeBSD supportMark Johnston2025-09-181-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is largely derived from existing Darwin support. FreeBSD apparently has better support for *at() system calls so doesn't require workarounds for a missing mknodat(). The implementation has a couple of warts however: - The extattr(2) system calls don't support anything akin to XATTR_CREATE or XATTR_REPLACE, so a racy workaround is implemented. - Attribute names cannot begin with "user." or "system." on ZFS. However FreeBSD's extattr(2) system calls support two dedicated namespaces for these two. So "user." or "system." prefixes are trimmed off from attribute names and instead EXTATTR_NAMESPACE_USER or EXTATTR_NAMESPACE_SYSTEM are picked and passed to extattr system calls accordingly. The 9pfs tests were verified to pass on the UFS, ZFS and tmpfs filesystems.

Still, we want to keep qio_channel_socket_readv() interface clean, as currently it allocate @fds only on success.

Note that pre-patch the behavior of Win32 and Linux realizations are inconsistent: we ignore failure for Win32, and assert success for Linux. How do we convert the callers? 1. Most of callers call qemu_socket_set_nonblock() on a freshly created socket fd, in conditions when we may simply report an error. Seems correct switching to error handling both for Windows (pre-patch error is ignored) and Linux (pre-patch we assert success). Anyway, we normally don't expect errors in these cases. Still in tests let's use &error_abort for simplicity. What are exclusions? 2. hw/virtio/vhost-user.c - we are inside #ifdef CONFIG_LINUX, so no damage in switching to error handling from assertion. 3. io/channel-socket.c: here we convert both old calls to qemu_socket_set_nonblock() and qemu_socket_set_block() to one new call. Pre-patch we assert success for Linux in qemu_socket_set_nonblock(), and ignore all other errors here. So, for Windows switch is a bit dangerous: we may get new errors or crashes(when error_abort is passed) in cases where we have silently ignored the error before (was it correct in all such cases, if they were?) Still, there is no other way to stricter API than take this risk. 4. util/vhost-user-server - compiled only for Linux (see util/meson.build), so we are safe, switching from assertion to &error_abort. Note: In qga/channel-posix.c we use g_warning(), where g_printerr() would actually be a better choice. Still let's for now follow common style of qga, where g_warning() is commonly used to print such messages, and no call to g_printerr(). Converting everything to use g_printerr() should better be another series. Reviewed-by: Daniel P.

* | treewide: handle result of qio_channel_set_blocking()Vladimir Sementsov-Ogievskiy2025-09-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we just always pass NULL as errp argument. That doesn't look good. Some realizations of interface may actually report errors. Channel-socket realization actually either ignore or crash on errors, but we are going to straighten it out to always reporting an errp in further commits. So, convert all callers to either handle the error (where environment allows) or explicitly use &error_abort. Take also a chance to change the return value to more convenient bool (keeping also in mind, that underlying realizations may return -1 on failure, not -errno). Suggested-by: Daniel P.

* | util: add qemu_set_blocking() functionVladimir Sementsov-Ogievskiy2025-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In generic code we have qio_channel_set_blocking(), which takes bool parameter, and qemu_file_set_blocking(), which as well takes bool parameter. At lower fd-layer we have a mess of functions: - enough direct calls to Unix-specific g_unix_set_fd_nonblocking() (of course, all calls are out of Windows-compatible code), which is glib specific with GError, which we can't use, and have to handle error-reporting by hand after the call. and several platform-agnostic qemu_* helpers: - qemu_socket_set_nonblock(), which asserts success for posix (still, in most cases we can handle the error in better way) and ignores error for win32 realization - qemu_socket_try_set_nonblock(), providing and error, but not errp, so we have to handle it after the call - qemu_socket_set_block(), which simply ignores an error Note, that *_socket_* word in original API, which we are going to substitute was intended, because Windows support these operations only for sockets. What leads to solution of dropping it again? 1. Having a QEMU-native wrapper with errp parameter for g_unix_set_fd_nonblocking() for non-socket fds worth doing, at least to unify error handling. 2. So, if try to keep _socket_ vs _file_ words, we'll have two actually duplicated functions for Linux, which actually will be executed successfully on any (good enough) fds, and nothing prevent using them improperly except for the name. That doesn't look good. 3. Naming helped us in the world where we crash on errors or ignore them. Now, with errp parameter, callers are intended to proper error checking. And for places where we really OK with crash-on-error semantics (like tests), we have an explicit &error_abort. So, this commit starts a series, which will effectively revert commit ff5927baa7ffb9 "util: rename qemu_*block() socket functions" (which in turn was reverting f9e8cacc5557e43 "oslib-posix: rename socket_set_nonblock() to qemu_set_nonblock()", so that's a long story). Now we don't simply rename, instead we provide the new API and update all the callers. This commit only introduces a new fd-layer wrapper. Next commits will replace old API calls with it, and finally remove old API. Reviewed-by: Daniel P.

This user-created SMMUv3 device is tied to a specific PCI bus provided by the user, so ensure the IOMMU ops are configured accordingly. Due to current limitations in QEMU’s device tree support, specifically its inability to properly present pxb-pcie based root complexes and their devices, the device tree support for the new SMMUv3 device is limited to cases where it is attached to the default pcie.0 root complex.

| * hw/pci: Introduce pci_setup_iommu_per_bus() for per-bus IOMMU ops retrievalShameer Kolothum2025-09-162-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, pci_setup_iommu() registers IOMMU ops for a given PCIBus. However, when retrieving IOMMU ops for a device using pci_device_get_iommu_bus_devfn(), the function checks the parent_dev and fetches IOMMU ops from the parent device, even if the current bus does not have any associated IOMMU ops. This behavior works for now because QEMU's IOMMU implementations are globally scoped, and host bridges rely on the bypass_iommu property to skip IOMMU translation when needed. However, this model will break with the soon to be introduced arm-smmuv3 device, which allows users to associate the IOMMU with a specific PCIe root complex (e.g., the default pcie.0 or a pxb-pcie root complex). For example, consider the following setup with multiple root complexes: -device arm-smmuv3,primary-bus=pcie.0,id=smmuv3.0 \ ... -device pxb-pcie,id=pcie.1,bus_nr=8,bus=pcie.0 \ -device pcie-root-port,id=pcie.port1,bus=pcie.1 \ -device virtio-net-pci,bus=pcie.port1 In Qemu, pxb-pcie acts as a special root complex whose parent is effectively the default root complex(pcie.0). Hence, though pcie.1 has no associated SMMUv3 as per above, pci_device_get_iommu_bus_devfn() will incorrectly return the IOMMU ops from pcie.0 due to the fallback via parent_dev. To fix this, introduce a new helper pci_setup_iommu_per_bus() that explicitly sets the new iommu_per_bus field in the PCIBus structure. This helper will be used in a subsequent patch that adds support for the new arm-smmuv3 device. Update pci_device_get_iommu_bus_devfn() to use iommu_per_bus when determining the correct IOMMU ops, ensuring accurate behavior for per-bus IOMMUs.

Note: Added a specific check to identify pxb-pcie to avoid matching pxb-cxl host bridges, which are also of type PCI_HOST_BRIDGE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The helpers form load-acquire/store-release pair and ensure that appropriate barriers are in place in case checks happen outside of BQL. Use them to replace open-coded checkers/setters across the code, to make sure that barriers are not missed. Helpers also make code a bit more readable.
