   increases the flexibility of KEXEC Handover. Also preparation for LUO

 - "Live Update Orchestrator" (Pasha Tatashin)
   is a major new feature targeted at cloud environments. Quoting the
   cover letter:

      This series introduces the Live Update Orchestrator, a kernel
      subsystem designed to facilitate live kernel updates using a
      kexec-based reboot. This capability is critical for cloud
      environments, allowing hypervisors to be updated with minimal
      downtime for running virtual machines. LUO achieves this by
      preserving the state of selected resources, such as memory,
      devices and their dependencies, across the kernel transition.

      As a key feature, this series includes support for preserving
      memfd file descriptors, which allows critical in-memory data, such
      as guest RAM or any other large memory region, to be maintained in
      RAM across the kexec reboot.

   Mike Rappaport merits a mention here, for his extensive review and
   testing work.

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
 "New PCI infrastructure and one architecture implementation for PCIe
  link encryption establishment via platform firmware services.

  This work is the result of multiple vendors coming to consensus on
  some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
  three vendor implementations, although only one is included in this
  pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
  changes have an ack from Tom, and the iommu/amd/ changes have an ack
  from Joerg.

  PCIe link encryption is made possible by the soup of acronyms
  mentioned in the shortlog below. Link Integrity and Data Encryption
  (IDE) is a protocol for installing keys in the transmitter and
  receiver at each end of a link. That protocol is transported over Data
  Object Exchange (DOE) mailboxes using PCI configuration requests.

  The aspect that makes this a "platform firmware service" is that the
  key provisioning and protocol is coordinated through a Trusted
  Execution Envrionment (TEE) Security Manager (TSM). That is either
  firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
  software (Intel TDX Connect / ARM CCA) running in a protected CPU
  mode.

  Now, the only reason to ask a TSM to run this protocol and install the
  keys rather than have a Linux driver do the same is so that later, a
  confidential VM can ask the TSM directly "can you certify this
  device?".

  That precludes host Linux from provisioning its own keys, because host
  Linux is outside the trust domain for the VM. It also turns out that
  all architectures, save for one, do not publish a mechanism for an OS
  to establish keys in the root port. So "TSM-established link
  encryption" is the only cross-architecture path for this capability
  for the foreseeable future.

  This unblocks the other arch implementations to follow in v6.20/v7.0,
  once they clear some other dependencies, and it unblocks the next
  phase of work to implement the end-to-end flow of confidential device
  assignment. The PCIe specification calls this end-to-end flow Trusted
  Execution Environment (TEE) Device Interface Security Protocol
  (TDISP).

  In the meantime, Linux gets a link encryption facility which has
  practical benefits along the same lines as memory encryption. It
  authenticates devices via certificates and may protect against
  interposer attacks trying to capture clear-text PCIe traffic.

  Summary:

   - Introduce the PCI/TSM core for the coordination of device
     authentication, link encryption and establishment (IDE), and later
     management of the device security operational states (TDISP).
     Notify the new TSM core layer of PCI device arrival and departure

   - Add a low level TSM driver for the link encryption establishment
     capabilities of the AMD SEV-TIO architecture

   - Add a library of helpers TSM drivers to use for IDE establishment
     and the DOE transport

   - Add skeleton support for 'bind' and 'guest_request' operations in
     support of TDISP"

 - Fix comment typo in mtty driver (Chu Guangqing)

 - Support for new hardware revision in the hisi_acc vfio-pci variant
   driver where the migration registers can now be accessed via the PF.
   When enabled for this support, the full BAR can be exposed to the
   user (Longfang Liu)

 - Fix vfio cdev support for VF token passing, using the correct size
   for the kernel structure, thereby actually allowing userspace to
   provide a non-zero UUID token. Also set the match token callback for
   the hisi_acc, fixing VF token support for this this vfio-pci variant
   driver (Raghavendra Rao Ananta)

 - Introduce internal callbacks on vfio devices to simplify and
   consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
   data, removing various ioctl intercepts with a more structured
   solution (Jason Gunthorpe)

 - Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
   to be exposed through dma-buf objects with lifecycle managed through
   move operations. This enables low-level interactions such as a
   vfio-pci based SPDK drivers interacting directly with dma-buf capable
   RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
   able to build upon this support to fill a long standing feature gap
   versus the legacy vfio type1 IOMMU backend with an implementation of
   P2P support for VM use cases that better manages the lifecycle of the
   P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)

   mechanisms in order to avoid a 3-way lockdep reported deadlock issue
   (Alex Williamson)

 - Fix a 32-bit overflow introduced via dma-buf support manifesting with
   large DMA buffers (Alex Mastro)

 - Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
   fault rather than at mmap time. This conversion serves both to make
   use of huge PFNMAPs but also to both avoid corrected RAS events
   during reset by now being subject to vfio-pci-core's use of
   unmap_mapping_range(), and to enable a device readiness test after
   reset (Ankit Agrawal)

 - Refactoring of vfio selftests to support multi-device tests and split
   code to provide better separation between IOMMU and device objects.
   This work also enables a new test suite addition to measure parallel
   device initialization latency (David Matlack)

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
     Williams)

   - Switch vmd from custom domain number allocator to the common
     allocator to prevent a potential race with new non-VMD buses (Dan
     Williams)

   - Enable Precision Time Measurement (PTM) only if device advertises
     support for a relevant role, to prevent invalid PTM Requests that
     cause ACS violations that are reported as AER Uncorrectable
     Non-Fatal errors (Mika Westerberg)

  Resource management:

   - Prevent resource tree corruption when BAR resize fails (Ilpo
     Järvinen)

   - Restore BARs to the original size if a BAR resize fails (Ilpo
     Järvinen)

   - Remove BAR release from BAR resize attempts by the xe, i915, and
     amdgpu drivers so the PCI core can restore BARs if the resize fails
     (Ilpo Järvinen)

   - Move Resizable BAR code to rebar.c (Ilpo Järvinen)

   - Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
     Järvinen)

   - Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
     Järvinen)

  Power management and error handling:

   - For drivers using PCI legacy suspend, save config state at suspend
     so that state (not any earlier state from enumeration, probe, or
     error recovery) will be restored when resuming (Lukas Wunner)

   - For devices with no driver or a driver that lacks power management,
     save config state at hibernate so that state (not any earlier state
     from enumeration, probe, or error recovery) will be restored when
     resuming (Lukas Wunner)

   - Save device config space on device addition, before driver binding,
     so error recovery works more reliably (Lukas Wunner)

   - Drop pci_save_state() from several drivers that no longer need it
     since the PCI core always does it and pci_restore_state() no longer
     invalidates the saved state (Lukas Wunner)

   - Document use of pci_save_state() by drivers to capture the state
     they want restored during error recovery (Lukas Wunner)

  Power control:

   - Add a struct pci_ops.assert_perst() function pointer to
     assert/deassert PCIe PERST# and implement it for the qcom driver
     (Krishna Chaitanya Chundru)

   - Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
     switch, which must be held in reset after poweron so the pwrctrl
     driver can configure the switch via I2C before bringing up the
     links (Krishna Chaitanya Chundru)

  Endpoint framework:

   - Convert the endpoint doorbell test to use a threaded IRQ to fix a
     'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)

   - Add endpoint VNTB MSI doorbell support to reduce latency between
     host and endpoint (Frank Li)

  New native PCIe controller drivers:

   - Add CIX Sky1 host controller DT binding and driver (Hans Zhang)

   - Add NXP S32G host controller DT binding and driver (Vincent
     Guittot)

   - Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
     Beznea)

   - Add SpacemiT K1 host controller DT binding and driver (Alex Elder)

  Amlogic Meson PCIe controller driver:

   - Update DT binding to name DBI region 'dbi', not 'elbi', and update
     driver to support both (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Move struct pci_host_bridge allocation from pci_host_common_init()
     to callers, which significantly simplifies pcie-apple (Marc
     Zyngier)

  Broadcom STB PCIe controller driver:

   - Disable advertising ASPM L0s support correctly (Jim Quinlan)

   - Add a panic/die handler to print diagnostic info in case PCIe
     caused an unrecoverable abort (Jim Quinlan)

  Cadence PCIe controller driver:

   - Add module support for Cadence platform host and endpoint
     controller driver (Manikandan K Pillai)

   - Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
     for new CIX Sky1 driver (Manikandan K Pillai)

  MediaTek PCIe controller driver:

   - Convert DT binding to YAML schema (Christian Marangi)

   - Add Airoha AN7583 DT compatible and driver support (Christian
     Marangi)

  Qualcomm PCIe controller driver:

   - Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)

   - Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
     sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
     schemas (Krzysztof Kozlowski)

   - Look up OPP using both frequency and data rate (not just frequency)
     so RPMh votes can account for both (Krishna Chaitanya Chundru)

  Rockchip DesignWare PCIe controller driver:

   - Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)

  STMicroelectronics STM32MP25 PCIe controller driver:

   - Fix a race between link training and endpoint register
     initialization (Christian Bruel)

   - Align endpoint allocations to match the ATU requirements (Christian
     Bruel)

  Synopsys DesignWare PCIe controller driver:

   - Clear L1 PM Substate Capability 'Supported' bits unless glue driver
     says it's supported, which prevents users from enabling non-working
     L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)

   - Remove now-superfluous L1SS disable code from tegra194 (Bjorn
     Helgaas)

   - Configure L1SS support in dw-rockchip when DT says
     'supports-clkreq' (Shawn Lin)

  TI Keystone PCIe controller driver:

   - Fail the probe instead of silently succeeding if ks_pcie_of_data
     didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)

   - Make keystone buildable as a loadable module, except on ARM32 where
     hook_fault_code() is __init (Siddharth Vadapalli)"
