2026-03-05drm/xe/xe_drm_ras: Add support for XE DRM RASRiana Tauro-0/+79
Allocate correctable, uncorrectable nodes for every xe device. Each node contains error component, counters and respective query counter functions. Add basic functionality to create and register drm nodes. Below operations can be performed using Generic netlink DRM RAS interface: 1) List Nodes: $ sudo ynl --family drm_ras --dump list-nodes [{'device-name': '0000:03:00.0', 'node-id': 0, 'node-name': 'correctable-errors', 'node-type': 'error-counter'}, {'device-name': '0000:03:00.0', 'node-id': 1, 'node-name': 'uncorrectable-errors', 'node-type': 'error-counter'}] 2) Get Error counters: $ sudo ynl --family drm_ras --dump get-error-counter --json '{"node-id":0}' [{'error-id': 1, 'error-name': 'core-compute', 'error-value': 0}, {'error-id': 2, 'error-name': 'soc-internal', 'error-value': 0}] 3) Get specific Error counter: $ sudo ynl --family drm_ras --do get-error-counter --json '{"node-id":0, "error-id":1}' {'error-id': 1, 'error-name': 'core-compute', 'error-value': 0} Signed-off-by: Riana Tauro <riana.tauro@intel.com> Reviewed-by: Raag Jadav <raag.jadav@intel.com> Link: https://patch.msgid.link/20260304074412.464435-9-riana.tauro@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2026-03-05drm/ras: Introduce the DRM RAS infrastructure over generic netlinkRodrigo Vivi-0/+49
Introduces the DRM RAS infrastructure over generic netlink. The new interface allows drivers to expose RAS nodes and their associated error counters to userspace in a structured and extensible way. Each drm_ras node can register its own set of error counters, which are then discoverable and queryable through netlink operations. This lays the groundwork for reporting and managing hardware error states in a unified manner across different DRM drivers. Currently it only supports error-counter nodes. But it can be extended later. The registration is also not tied to any drm node, so it can be used by accel devices as well. It uses the new and mandatory YAML description format stored in Documentation/netlink/specs/. This forces a single generic netlink family namespace for the entire drm: "drm-ras". But multiple-endpoints are supported within the single family. Any modification to this API needs to be applied to Documentation/netlink/specs/drm_ras.yaml before regenerating the code: $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml --mode uapi --header \ -o include/uapi/drm/drm_ras.h $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml --mode kernel \ --header -o drivers/gpu/drm/drm_ras_nl.h $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml \ --mode kernel --source -o drivers/gpu/drm/drm_ras_nl.c Cc: Zack McKevitt <zachary.mckevitt@oss.qualcomm.com> Cc: Lijo Lazar <lijo.lazar@amd.com> Cc: Hawking Zhang <Hawking.Zhang@amd.com> Cc: Jakub Kicinski <kuba@kernel.org> Cc: David S.

2026-03-05net: ethtool: Track pause storm eventsMohsin Bashir-0/+1
With TX pause enabled, if a device is unable to pass packets up to the stack (e.g., CPU is hanged), the device can cause pause storm. Given that devices can have native support to protect the neighbor from such flooding, such events need some tracking. This support is to track TX pause storm events for better observability.

2026-02-25sched/deadline: Add reporting of runtime left & abs deadline to ↵Tommaso Cucinotta-0/+3
sched_getattr() for DEADLINE tasks The SCHED_DEADLINE scheduler allows reading the statically configured run-time, deadline, and period parameters through the sched_getattr() system call. However, there is no immediate way to access, from user space, the current parameters used within the scheduler: the instantaneous runtime left in the current cycle, as well as the current absolute deadline. The `flags' sched_getattr() parameter, so far mandated to contain zero, now supports the SCHED_GETATTR_FLAG_DL_DYNAMIC=1 flag, to request retrieval of the leftover runtime and absolute deadline, converted to a CLOCK_MONOTONIC reference, instead of the statically configured parameters. This feature is useful for adaptive SCHED_DEADLINE tasks that need to modify their behavior depending on whether or not there is enough runtime left in the current period, and/or what is the current absolute deadline. Notes: - before returning the instantaneous parameters, the runtime is updated; - the abs deadline is returned shifted from rq_clock() to ktime_get_ns(), in CLOCK_MONOTONIC reference; this causes multiple invocations from the same period to return values that may differ for a few ns (showing some small drift), albeit the deadline doesn't move, in rq_clock() reference; - the abs deadline value returned to user-space, as unsigned 64-bit value, can represent nearly 585 years since boot time; - setting flags=0 provides the old behavior (retrieve static parameters). See also the notes from discussion held at OSPM 2025 on the topic "Making user space aware of current deadline-scheduler parameters".

2026-02-24drm/xe/uapi: Introduce a flag to disallow vm overcommit in fault modeThomas Hellström-0/+6
Some compute applications may try to allocate device memory to probe how much device memory is actually available, assuming that the application will be the only one running on the particular GPU. That strategy fails in fault mode since it allows VM overcommit. While this could be resolved in user-space it's further complicated by cgroups potentially restricting the amount of memory available to the application. Introduce a vm create flag, DRM_XE_VM_CREATE_NO_VM_OVERCOMMIT, that allows fault mode to mimic the behaviour of !fault mode WRT this. It blocks evicting same vm bos during VM_BIND processing. However, it does *not* block evicting same-vm bos during pagefault processing, preferring eviction rather than VM banning in OOM situations.

2026-02-24drm/nouveau: Add DRM_IOCTL_NOUVEAU_GET_ZCULL_INFOMel Henning-0/+66
Add kernel-side support for using the zcull hardware in nvidia gpus. zcull aims to improve memory bandwidth by using an early approximate depth test, similar to hierarchical Z on an AMD card. Add a new ioctl that exposes zcull information that has been read from the hardware. Userspace uses each of these parameters either in a heuristic for determining zcull region parameters or in the calculation of a buffer size. It appears the hardware hasn't changed its structure for these values since FERMI_C (circa 2011), so the assumption is that it won't change on us too quickly, and is therefore reasonable to include in UAPI. This bypasses the nvif layer and instead accesses nvkm_gr directly, which mirrors existing usage of nvkm_gr_units(). There is no nvif object for nvkm_gr yet, and adding one is not trivial.

2026-02-23rseq: slice ext: Ensure rseq feature size differs from original rseq sizeMathieu Desnoyers-4/+22
Before rseq became extensible, its original size was 32 bytes even though the active rseq area was only 20 bytes. This had the following impact in terms of userspace ecosystem evolution: * The GNU libc between 2.35 and 2.39 expose a __rseq_size symbol set to 32, even though the size of the active rseq area is really 20. * The GNU libc 2.40 changes this __rseq_size to 20, thus making it express the active rseq area. * Starting from glibc 2.41, __rseq_size corresponds to the AT_RSEQ_FEATURE_SIZE from getauxval(3). This means that users of __rseq_size can always expect it to correspond to the active rseq area, except for the value 32, for which the active rseq area is 20 bytes. Exposing a 32 bytes feature size would make life needlessly painful for userspace. Therefore, add a reserved field at the end of the rseq area to bump the feature size to 33 bytes. This reserved field is expected to be replaced with whatever field will come next, expecting that this field will be larger than 1 byte. The effect of this change is to increase the size from 32 to 64 bytes before we actually have fields using that memory. Clarify the allocation size and alignment requirements in the struct rseq uapi comment. Change the value returned by getauxval(AT_RSEQ_ALIGN) to return the value of the active rseq area size rounded up to next power of 2, which guarantees that the rseq structure will always be aligned on the nearest power of two large enough to contain it, even as it grows. Change the alignment check in the rseq registration accordingly. This will minimize the amount of ABI corner-cases we need to document and require userspace to play games with. The rule stays simple when __rseq_size != 32: #define rseq_field_available(field) (__rseq_size >= offsetofend(struct rseq_abi, field)) Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://patch.msgid.link/20260220200642.1317826-3-mathieu.desnoyers@efficios.com

2026-02-19fs: add generic FS_IOC_SHUTDOWN definitionsNamjae Jeon-0/+12
Currently, several filesystems (e.g., xfs, ext4, btrfs) implement a "shutdown" or "going down" ioctl to simulate filesystem force a shutdown. While they often use the same underlying numeric value, the definition is duplicated across filesystem headers or private definitions. Add generic definitions for FS_IOC_SHUTDOWN in uapi/linux/fs.h. This allows new filesystems (like ntfs) to implement this feature using a standard VFS definition and paves the way for existing filesystems to unify their definitions later. The flag names are standardized as FS_SHUTDOWN_* to be consistent with the ioctl name, replacing the historical GOING_DOWN naming convention. Reviewed-by: "Darrick J.

2026-02-17include: uapi: netfilter_bridge.h: Cover for musl libcPhil Sutter-0/+4
Musl defines its own struct ethhdr and thus defines __UAPI_DEF_ETHHDR to zero. To avoid struct redefinition errors, user space is therefore supposed to include netinet/if_ether.h before (or instead of) linux/if_ether.h. To relieve them from this burden, include the libc header here if not building for kernel space.

2026-02-16io_uring/bpf_filter: pass in expected filter payload sizeJens Axboe-1/+7
It's quite possible that opcodes that have payloads attached to them, like IORING_OP_OPENAT/OPENAT2 or IORING_OP_SOCKET, that these paylods can change over time. For example, on the openat/openat2 side, the struct open_how argument is extensible, and could be extended in the future to allow further arguments to be passed in. Allow registration of a cBPF filter to give the size of the filter as seen by userspace. If that filter is for an opcode that takes extra payload data, allow it if the application payload expectation is the same size than the kernels. If that is the case, the kernel supports filtering on the payload that the application expects. If the size differs, the behavior depends on the IO_URING_BPF_FILTER_SZ_STRICT flag: 1) If IO_URING_BPF_FILTER_SZ_STRICT is set and the size expectation differs, fail the attempt to load the filter. 2) If IO_URING_BPF_FILTER_SZ_STRICT isn't set, allow the filter if the userspace pdu size is smaller than what the kernel offers. 3) Regardless if IO_URING_BPF_FILTER_SZ_STRICT, fail loading the filter if the userspace pdu size is bigger than what the kernel supports. An attempt to load a filter due to sizing will error with -EMSGSIZE. For that error, the registration struct will have filter->pdu_size populated with the pdu size that the kernel uses.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull more misc vfs updates from Christian Brauner: "Features: - Optimize close_range() from O(range size) to O(active FDs) by using find_next_bit() on the open_fds bitmap instead of linearly scanning the entire requested range. This is a significant improvement for large-range close operations on sparse file descriptor tables. - Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only. Add tracepoints for fs-verity enable and verify operations, replacing the previously removed debug printk's. - Prevent nfsd from exporting special kernel filesystems like pidfs and nsfs. These filesystems have custom ->open() and ->permission() export methods that are designed for open_by_handle_at(2) only and are incompatible with nfsd. Update the exportfs documentation accordingly. Fixes: - Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used on a non-null-terminated decrypted directory entry name from fscrypt. This triggered on encrypted lower layers when the decrypted name buffer contained uninitialized tail data. The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and name_is_dot_dotdot() helpers, replacing various open-coded "." and ".." checks across the tree. - Fix read-only fsflags not being reset together with xflags in vfs_fileattr_set(). Currently harmless since no read-only xflags overlap with flags, but this would cause inconsistencies for any future shared read-only flag - Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the target process is in a different pid namespace. This lets userspace distinguish "process exited" from "process in another namespace", matching glibc's pidfd_getpid() behavior Cleanups: - Use C-string literals in the Rust seq_file bindings, replacing the kernel::c_str!() macro (available since Rust 1.77) - Fix typo in d_walk_ret enum comment, add porting notes for the readlink_copy() calling convention change" * tag 'vfs-7.0-rc1.misc.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: add porting notes about readlink_copy() pidfs: return -EREMOTE when PIDFD_GET_INFO is called on another ns nfsd: do not allow exporting of special kernel filesystems exportfs: clarify the documentation of open()/permission() expotrfs ops fsverity: add tracepoints fs: add FS_XFLAG_VERITY for fs-verity files rust: seq_file: replace `kernel::c_str!` with C-Strings fs: dcache: fix typo in enum d_walk_ret comment ovl: use name_is_dot* helpers in readdir code fs: add helpers name_is_dot{,dot,_dotdot} ovl: Fix uninit-value in ovl_fill_real fs: reset read-only fsflags together with xflags fs/file: optimize close_range() complexity from O(N) to O(Sparse)

This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit bf2c3138ae36 ("Merge tag 'kvm-x86-pmu-6.20' ...") - Disallow changing the virtual CPU model if L2 is active, for all the same reasons KVM disallows change the model after the first KVM_RUN - Fix a bug where KVM would incorrectly reject host accesses to PV MSRs when running with KVM_CAP_ENFORCE_PV_FEATURE_CPUID enabled, even if those were advertised as supported to userspace, - Fix a bug with protected guest state (SEV-ES/SNP and TDX) VMs, where KVM would attempt to read CR3 configuring an async #PF entry - Fail the build if EXPORT_SYMBOL_GPL or EXPORT_SYMBOL is used in KVM (for x86 only) to enforce usage of EXPORT_SYMBOL_FOR_KVM_INTERNAL. Only a few exports that are intended for external usage, and those are allowed explicitly - When checking nested events after a vCPU is unblocked, ignore -EBUSY instead of WARNing. Userspace can sometimes put the vCPU into what should be an impossible state, and spurious exit to userspace on -EBUSY does not really do anything to solve the issue - Also throw in the towel and drop the WARN on INIT/SIPI being blocked when vCPU is in Wait-For-SIPI, which also resulted in playing whack-a-mole with syzkaller stuffing architecturally impossible states into KVM - Add support for new Intel instructions that don't require anything beyond enumerating feature flags to userspace - Grab SRCU when reading PDPTRs in KVM_GET_SREGS2 - Add WARNs to guard against modifying KVM's CPU caps outside of the intended setup flow, as nested VMX in particular is sensitive to unexpected changes in KVM's golden configuration - Add a quirk to allow userspace to opt-in to actually suppress EOI broadcasts when the suppression feature is enabled by the guest (currently limited to split IRQCHIP, i.e. userspace I/O APIC). Sadly, simply fixing KVM to honor Suppress EOI Broadcasts isn't an option as some userspaces have come to rely on KVM's buggy behavior (KVM advertises Supress EOI Broadcast irrespective of whether or not userspace I/O APIC supports Directed EOIs) - Clean up KVM's handling of marking mapped vCPU pages dirty - Drop a pile of *ancient* sanity checks hidden behind in KVM's unused ASSERT() macro, most of which could be trivially triggered by the guest and/or user, and all of which were useless - Fold "struct dest_map" into its sole user, "struct rtc_status", to make it more obvious what the weird parameter is used for, and to allow fropping these RTC shenanigans if CONFIG_KVM_IOAPIC=n - Bury all of ioapic.h, i8254.h and related ioctls (including KVM_CREATE_IRQCHIP) behind CONFIG_KVM_IOAPIC=y - Add a regression test for recent APICv update fixes - Handle "hardware APIC ISR", a.k.a. SVI, updates in kvm_apic_update_apicv() to consolidate the updates, and to co-locate SVI updates with the updates for KVM's own cache of ISR information - Drop a dead function declaration - Minor cleanups x86 (Intel): - Rework KVM's handling of VMCS updates while L2 is active to temporarily switch to vmcs01 instead of deferring the update until the next nested VM-Exit. The deferred updates approach directly contributed to several bugs, was proving to be a maintenance burden due to the difficulty in auditing the correctness of deferred updates, and was polluting "struct nested_vmx" with a growing pile of booleans - Fix an SGX bug where KVM would incorrectly try to handle EPCM page faults, and instead always reflect them into the guest. Since KVM doesn't shadow EPCM entries, EPCM violations cannot be due to KVM interference and can't be resolved by KVM - Fix a bug where KVM would register its posted interrupt wakeup handler even if loading kvm-intel.ko ultimately failed - Disallow access to vmcb12 fields that aren't fully supported, mostly to avoid weirdness and complexity for FRED and other features, where KVM wants enable VMCS shadowing for fields that conditionally exist - Print out the "bad" offsets and values if kvm-intel.ko refuses to load (or refuses to online a CPU) due to a VMCS config mismatch x86 (AMD): - Drop a user-triggerable WARN on nested_svm_load_cr3() failure - Add support for virtualizing ERAPS. Note, correct virtualization of ERAPS relies on an upcoming, publicly announced change in the APM to reduce the set of conditions where hardware (i.e. KVM) *must* flush the RAP - Ignore nSVM intercepts for instructions that are not supported according to L1's virtual CPU model - Add support for expedited writes to the fast MMIO bus, a la VMX's fastpath for EPT Misconfig - Don't set GIF when clearing EFER.SVME, as GIF exists independently of SVM, and allow userspace to restore nested state with GIF=0 - Treat exit_code as an unsigned 64-bit value through all of KVM - Add support for fetching SNP certificates from userspace - Fix a bug where KVM would use vmcb02 instead of vmcb01 when emulating VMLOAD or VMSAVE on behalf of L2 - Misc fixes and cleanups x86 selftests: - Add a regression test for TPR<=>CR8 synchronization and IRQ masking - Overhaul selftest's MMU infrastructure to genericize stage-2 MMU support, and extend x86's infrastructure to support EPT and NPT (for L2 guests) - Extend several nested VMX tests to also cover nested SVM - Add a selftest for nested VMLOAD/VMSAVE - Rework the nested dirty log test, originally added as a regression test for PML where KVM logged L2 GPAs instead of L1 GPAs, to improve test coverage and to hopefully make the test easier to understand and maintain guest_memfd: - Remove kvm_gmem_populate()'s preparation tracking and half-baked hugepage handling. SEV/SNP was the only user of the tracking and it can do it via the RMP - Retroactively document and enforce (for SNP) that KVM_SEV_SNP_LAUNCH_UPDATE and KVM_TDX_INIT_MEM_REGION require the source page to be 4KiB aligned, to avoid non-trivial complexity for something that no known VMM seems to be doing and to avoid an API special case for in-place conversion, which simply can't support unaligned sources - When populating guest_memfd memory, GUP the source page in common code and pass the refcounted page to the vendor callback, instead of letting vendor code do the heavy lifting. Doing so avoids a looming deadlock bug with in-place due an AB-BA conflict betwee mmap_lock and guest_memfd's filemap invalidate lock Generic: - Fix a bug where KVM would ignore the vCPU's selected address space when creating a vCPU-specific mapping of guest memory.
