drm/xe: Allow scratch page under fault mode for certain platform
Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.
v2: Refine commit message (Thomas)
v3: Move the scratch page flag check to after scratch page wa (Thomas)
v4: drop NEEDS_SCRATCH macro (matt)
Add a comment to DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE

drm/xe/uapi: Add DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR
Add the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag, which is used to create unpopulated virtual memory areas (VMAs) without memory backing or GPU page tables. These VMAs are referred to as CPU address mirror VMAs. The idea is that upon a page fault or prefetch, the memory backing and GPU page tables will be populated. CPU address mirror VMAs only update GPUVM state; they do not have an internal page table (PT) state, nor do they have GPU mappings. It is expected that CPU address mirror VMAs will be mixed with buffer object (BO) VMAs within a single VM. In other words, system allocations and runtime allocations can be mixed within a single user-mode driver (UMD) program. Expected usage: - Bind the entire virtual address (VA) space upon program load using the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag. - If a buffer object (BO) requires GPU mapping (runtime allocation), allocate a CPU address using mmap(PROT_NONE), bind the BO to the mmapped address using existing bind IOCTLs. If a CPU map of the BO is needed, mmap it again to the same CPU address using mmap(MAP_FIXED) - If a BO no longer requires GPU mapping, munmap it from the CPU address space and them bind the mapping address with the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag. - Any malloc'd or mmapped CPU address accessed by the GPU will be faulted in via the SVM implementation (system allocation). - Upon freeing any mmapped or malloc'd data, the SVM implementation will remove GPU mappings. Only supporting 1 to 1 mapping between user address space and GPU address space at the moment as that is the expected use case. uAPI defines interface for non 1 to 1 but enforces 1 to 1, this restriction can be lifted if use cases arrise for non 1 to 1 mappings. This patch essentially short-circuits the code in the existing VM bind paths to avoid populating page tables when the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag is set. v3: - Call vm_bind_ioctl_ops_fini on -ENODATA - Don't allow DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR on non-faulting VMs - s/DRM_XE_VM_BIND_FLAG_SYSTEM_ALLOCATOR/DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR (Thomas) - Rework commit message for expected usage (Thomas) - Describe state of code after patch in commit message (Thomas) v4: - Fix alignment (Checkpatch) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-9-matthew.brost@intel.com |

drm/xe/uapi: Use hint for guc to set GT frequency
Allow user to provide a low latency hint. When set, KMD sends a hint
to GuC which results in special handling for that process. SLPC will
ramp the GT frequency aggressively every time it switches to this
process.
We need to enable the use of SLPC Compute strategy during init, but
it will apply only to processes that set this bit during process
creation.
Improvement with this approach as below:

with an array of supported sampling rates sorted in the fastest sampling
rate first order. sampling_rates in struct drm_xe_query_eu_stall will
point to the array of sampling rates.
Any capabilities in EU stall sampling as of this patch are considered
as base capabilities. New capability bits will be added for any new
functionality added later.
v12: Rename has_eu_stall_sampling_support() to
xe_eu_stall_supported_on_platform() and move it to header file.
v11: Check if EU stall sampling is supported on the platform.
v10: Change comments and variable names as per feedback
v9: Move reserved fields above num_sampling_rates in
struct drm_xe_query_eu_stall.
v7: Change sampling_rates from a pointer to flexible array.
v6: Include EU stall sampling rates information and
per XeCore buffer size in the query information.

drm/xe/uapi: Introduce API for EU stall sampling
A new hardware feature first introduced in PVC gives capability to
periodically sample EU stall state and record counts for different stall
reasons, on a per IP basis, aggregate across all EUs in a subslice and
record the samples in a buffer in each subslice. Eventually, the aggregated
data is written out to a buffer in the memory. This feature is also
supported in XE2 and later architecture GPUs.
Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the
driver from the user space to do initial setup and obtain a file descriptor
for the EU stall data stream. Input parameter to the IOCTL is a struct
drm_xe_observation_param in which observation_type should be set to
DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be
DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of
drm_xe_ext_set_property structures in which each structure has a pair of
property and value. The EU stall sampling input properties are defined in
drm_xe_eu_stall_property_id enum.
With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space
can enable and disable EU stall sampling with the IOCTLs:
DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE.
User space can also call poll() to check for availability of data in the
buffer. The data can be read with read(). Finally, the file descriptor
can be closed with close().
v11: Changed a couple of variables in struct eu_stall_open_properties
from unsigned int to int.
v10: Use extension number while parsing chain of extensions.
Remove function description for static functions.
Move code around as per review feedback.
v9: Changed some u32 to unsigned int.
Moved some code around as per review feedback from v8.
v8: Used div_u64 instead of / to fix 32-bit build issue.
Changed copyright year in xe_eu_stall.c/h to 2025.
v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT
to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with
OA. Renamed the corresponding internal variables.
Fixed some commit messages based on review feedback.
v6: Change the input sampling rate to GPU cycles instead of
GPU cycles multiplier.

net: ethtool: tsconfig: Fix netlink type of hwtstamp flags
Fix the netlink type for hardware timestamp flags, which are represented
as a bitset of flags. Although only one flag is supported currently, the
correct netlink bitset type should be used instead of u32 to keep
consistency with other fields. Address this by adding a new named string
set description for the hwtstamp flag structure.
The code has been introduced in the current release so the uAPI change is
still okay.

drm/xe/pxp/uapi: Add API to mark a BO as using PXP
The driver needs to know if a BO is encrypted with PXP to enable the
display decryption at flip time.
Furthermore, we want to keep track of the status of the encryption and
reject any operation that involves a BO that is encrypted using an old
key. There are two points in time where such checks can kick in:
1 - at VM bind time, all operations except for unmapping will be
rejected if the key used to encrypt the BO is no longer valid. This
check is opt-in via a new VM_BIND flag, to avoid a scenario where a
malicious app purposely shares an invalid BO with a non-PXP aware
app (such as a compositor). If the VM_BIND was failed, the
compositor would be unable to display anything at all. Allowing the
bind to go through means that output still works, it just displays
garbage data within the bounds of the illegal BO.
2 - at job submission time, if the queue is marked as using PXP, all
objects bound to the VM will be checked and the submission will be
rejected if any of them was encrypted with a key that is no longer
valid.
Note that there is no risk of leaking the encrypted data if a user does
not opt-in to those checks; the only consequence is that the user will
not realize that the encryption key is changed and that the data is no
longer valid.
v2: Better commnnts and descriptions (John), rebase
v3: Properly return the result of key_assign up the stack, do not use
xe_bo in display headers (Jani)
v4: improve key_instance variable documentation (John)

PXP prerequisites (SW proxy and HuC auth via GSC) are completed asynchronously from driver load, which means that userspace can start submitting before we're ready to start a PXP session.

drm/xe/pxp/uapi: Add userspace and LRC support for PXP-using queues
Userspace is required to mark a queue as using PXP to guarantee that the PXP instructions will work. In addition to managing the PXP sessions, when a PXP queue is created the driver will set the relevant bits in its context control register. On submission of a valid PXP queue, the driver will validate all encrypted objects mapped to the VM to ensured they were encrypted with the current key. v2: Remove pxp_types include outside of PXP code (Jani), better comments and code cleanup (John) v3: split the internal PXP management to a separate patch for ease of review. re-order ioctl checks to always return -EINVAL if parameters are invalid, rebase on msix changes.

NFSD 6.14 Release Notes
Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer.

An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer.

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Batch sizing of multiple BARs while memory decoding is disabled
instead of disabling/enabling decoding for each BAR individually;
this optimizes virtualized environments where toggling decoding
enable is expensive (Alex Williamson)
- Add host bridge .enable_device() and .disable_device() hooks for
bridges that need to configure things like Requester ID to StreamID
mapping when enabling devices (Frank Li)
- Extend struct pci_ecam_ops with .enable_device() and
.disable_device() hooks so drivers that use pci_host_common_probe()
instead of their own .probe() have a way to set the
.enable_device() callbacks (Marc Zyngier)
- Drop 'No bus range found' message so we don't complain when DTs
don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)
- Rename the drivers/pci/of_property.c struct of_pci_range to
of_pci_range_entry to avoid confusion with the global of_pci_range
in include/linux/of_address.h (Bjorn Helgaas)
Driver binding:
- Update resource request API documentation to encourage callers to
supply a driver name when requesting resources (Philipp Stanner)
- Export pci_intx_unmanaged() and pcim_intx() (always managed) so
callers of pci_intx() (which is sometimes managed) can explicitly
choose the one they need (Philipp Stanner)
- Convert drivers from pci_intx() to always-managed pcim_intx() or
never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)
- Remove pci_intx_unmanaged() since pci_intx() is now always
unmanaged and pcim_intx() is always managed (Philipp Stanner)
Error handling:
- Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
logging rather than building their own (Ilpo Järvinen)
- Move TLP Log handling to its own file (Ilpo Järvinen)
- Store number of supported End-End TLP Prefixes always so we can
read the correct number of DWORDs from the TLP Prefix Log (Ilpo
Järvinen)
- Read TLP Prefixes in addition to the Header Log in
pcie_read_tlp_log() (Ilpo Järvinen)
- Add pcie_print_tlp_log() to consolidate printing of TLP Header and
Prefix Log (Ilpo Järvinen)
- Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
BIOSes that don't configure it correctly (Takashi Iwai)
ASPM:
- Save parent L1 PM Substates config so when we restore it along with
an endpoint's config, the parent info isn't junk (Jian-Hong Pan)
Power management:
- Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
the system can't wake up from suspend (Werner Sembach)
Endpoint framework:
- Destroy the EPC device in devm_pci_epc_destroy(), which previously
didn't call devres_release() (Zijun Hu)
- Finish virtual EP removal in pci_epf_remove_vepf(), which
previously caused a subsequent pci_epf_add_vepf() to fail with
-EBUSY (Zijun Hu)
- Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
don't depend on the BAR_MASK reset value being larger than the
requested BAR size (Niklas Cassel)
- Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
reads from bypassing the iATU if we reduced the BAR size (Niklas
Cassel)
- Verify address alignment when programming iATU so we don't attempt
to write bits that are read-only because of the BAR size, which
could lead to directing accesses to the wrong address (Niklas
Cassel)
- Implement artpec6 pci_epc_features so we can rely on all drivers
supporting it so we can use it in EPC core code (Niklas Cassel)

trying to change their size (Niklas Cassel)
- Verify that requested BAR size is a power of two when endpoint
driver sets the BAR (Niklas Cassel)

Loongarch:
* Clear LLBCTL if secondary mmu mapping changes.
* Add hypercall service support for usermode VMM.
x86:
* Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a
direct call to kvm_tdp_page_fault() when RETPOLINE is enabled.
* Ensure that all SEV code is compiled out when disabled in Kconfig, even
if building with less brilliant compilers.
* Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes.
* Use str_enabled_disabled() to replace open coded strings.
* Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache
prior to every VM-Enter.
* Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities
instead of just those where KVM needs to manage state and/or explicitly
enable the feature in hardware. Along the way, refactor the code to make
it easier to add features, and to make it more self-documenting how KVM
is handling each feature.
* Rework KVM's handling of VM-Exits during event vectoring; this plugs holes
where KVM unintentionally puts the vCPU into infinite loops in some scenarios
(e.g. if emulation is triggered by the exit), and brings parity between VMX
and SVM.
* Add pending request and interrupt injection information to the kvm_exit and
kvm_entry tracepoints respectively.
* Fix a relatively benign flaw where KVM would end up redoing RDPKRU when
loading guest/host PKRU, due to a refactoring of the kernel helpers that
didn't account for KVM's pre-checking of the need to do WRPKRU.
* Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE
specifically went to userspace, and all the others did not; the new code
need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not.
* As part of enabling TDX virtual machines, support support separation of
private/shared EPT into separate roots. When TDX will be enabled, operations
on private pages will need to go through the privileged TDX Module via SEAMCALLs;
as a result, they are limited and relatively slow compared to reading a PTE.
The patches included in 6.14 allow KVM to keep a mirror of the private EPT in
host memory, and define entries in kvm_x86_ops to operate on external page
tables such as the TDX private EPT.
* The recently introduced conversion of the NX-page reclamation kthread to
vhost_task moved the task under the main process. The task is created as
soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that
didn't expect to see any child task of the VM process until it started
creating its own userspace threads. In particular crosvm refuses to fork()
if procfs shows any child task, so unbreak it by creating the task lazily.
This is arguably a userspace bug, as there can be other kinds of legitimate
worker tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they show
as "Kthread: 1" in proc/.../status?
x86 - Intel:
* Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit
while L2 is active, while ultimately results in a hardware-accelerated L1
EOI effectively being lost.
* Honor event priority when emulating Posted Interrupt delivery during nested
VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the
interrupt.
* Rework KVM's processing of the Page-Modification Logging buffer to reap
entries in the same order they were created, i.e. to mark gfns dirty in the
same order that hardware marked the page/PTE dirty.
* Misc cleanups.
Generic:
* Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when
setting memory regions and add a dedicated API for setting KVM-internal
memory regions. The API can then explicitly disallow all flags for
KVM-internal memory regions.
* Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.
* Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that
isn't yet onlined.
* Gracefully handle xarray insertion failures; even though such failures are
impossible in practice after xa_reserve(), reserving an entry is always followed
by xa_store() which does not know (or differentiate) whether there was an
xa_reserve() before or not.
RISC-V:
* Zabha, Svvptc, and Ziccrse extension support for guests. None of them
require anything in KVM except for detecting them and marking them
as supported; Zabha adds byte and halfword atomic operations, while the
others are markers for specific operation of the TLB and of LL/SC
instructions respectively.
* Virtualize SBI system suspend extension for Guest/VM
* Support firmware counters which can be used by the guests to collect
statistics about traps that occur in the host.
Selftests:
* Rework vcpu_get_reg() to return a value instead of using an out-param, and
update all affected arch code accordingly.
* Convert the max_guest_memory_test into a more generic mmu_stress_test.
The basic gist of the "conversion" is to have the test do mprotect() on
guest memory while vCPUs are accessing said memory, e.g. to verify KVM
and mmu_notifiers are working as intended.
* Play nice with treewrite builds of unsupported architectures, e.g. arm
(32-bit), as KVM selftests' Makefile doesn't do anything to ensure the
target architecture is actually one KVM selftests supports.
* Use the kernel's $(ARCH) definition instead of the target triple for arch
specific directories, e.g. arm64 instead of aarch64, mainly so as not to
be different from the rest of the kernel.
* Ensure that format strings for logging statements are checked by the
compiler even when the logging statement itself is disabled.
* Attempt to whack the last LLC references/misses mole in the Intel PMU
counters test by adding a data load and doing CLFLUSH{OPT} on the data
instead of the code being executed. It seems that modern Intel CPUs
have learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that events
are counting correctly without actually knowing what the events count
given the underlying hardware; this can happen if Intel reuses a
formerly microarchitecture-specific event encoding as an architectural
event, as was the case for Top-Down Slots.
