DRM Rust changes for v7.2-rc1
- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):
- Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
drivers, allowing driver structs to hold device resources like
pci::Bar and IoMem directly with a lifetime tied to the binding
scope, removing the need for Devres indirection and ARef<Device>.
- Replace drvdata() with scoped registration data on the auxiliary
bus, using the new ForLt trait to thread lifetimes through
registrations. Remove drvdata() and driver_type.
- DRM:
- Add GPUVM immediate mode abstraction for Rust GPU drivers:
- In immediate mode, GPU virtual address space state is updated
during job execution (in the DMA fence signalling critical path),
keeping the GPUVM and the GPU's address space always in sync.
- Provide GpuVm, GpuVa, and GpuVmBo types for managing address
spaces, virtual mappings, and GEM object backing respectively.
- Provide split-merge map/unmap operations that handle partial
overlaps with existing mappings.
- drm_exec integration for dma_resv locking and GEM object
validation based on the external/evicted object lists are not
yet covered and planned as follow-up work.
- Introduce DeviceContext type state for drm::Device, allowing
drivers to restrict operations to contexts where the device is
guaranteed to be registered (or not yet registered) with userspace.
- Add FEAT_RENDER flag to the Driver trait for render node support.
- Nova:
- Hopper/Blackwell enablement:
- Add GPU identification and architecture-based HAL selection for
Hopper (GH100) and Blackwell (GB100, GB202).
- Implement the FSP (Foundation Security Processor) boot path used by
Hopper and Blackwell, including FSP falcon engine support, EMEM
operations, MCTP/NVDM message infrastructure, and FSP Chain of
Trust boot with GSP lockdown release.
- Add support for 32-bit firmware images and auto-detection of
firmware image format.
- Add architecture-specific framebuffer, sysmem flush, PCI config
mirror, DMA mask, and WPR/non-WPR heap sizing.
- GSP boot and unload:
- Refactor the GSP boot process into a chipset-specific HAL,
keeping the SEC2 and FSP boot paths separated cleanly.
- Implement proper driver unload: send UNLOADING_GUEST_DRIVER
command, run Booter Unloader and FWSEC-SB upon unbinding, and run
the unload bundle on Gsp::boot() failure. This removes the need
for a manual GPU reset between driver unbind and re-probe.
- GA100 support:
- Add support for the GA100 GPU, including IFR header detection and
skipping, correct fwsignature selection, conditional FRTS boot,
and documentation of the IFR header layout.
- VBIOS hardening and refactoring:
- Harden VBIOS parsing with checked arithmetic, bounds-checked
accesses, and FromBytes-based structure reads throughout the FWSEC
and Falcon data paths. Simplify the overall VBIOS module
structure.
- HRT adoption:
- Use lifetime-parameterized pci::Bar directly, replacing the
Arc<Devres<Bar0>> indirection. Replace ARef<Device> with &'bound
Device in SysmemFlush and the GSP sequencer. Separate the driver
type from driver data.
- Misc:
- Rename module names to kebab-case (nova-drm, nova-core).
- Require little-endian in Kconfig, making the existing assumption
explicit.
- Tyr:
- Define comprehensive typed register blocks for GPU_CONTROL,
JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
and DOORBELL_BLOCK using the kernel register!() macro. This replaces
manual bit manipulation with typed register and field accessors.
- Add shmem-backed GEM objects and set DMA mask based on GPU physical
address width.
- Adopt HRT: separate driver type from driver data, and use IoMem
directly instead of Devres for register access during probe.
- Move clock cleanup into a Drop implementation.

Document the Display Unit (DU) support for the RZ/T2H and RZ/N2H SoCs.
The DU block on RZ/T2H is functionally equivalent to the RZ/G2UL DU and
supports the DPI interface, but includes SoC-specific register differences
and has no reset control. Add a dedicated compatible string to represent
this variant and update the allOf constraints accordingly.
As the DU implementation on RZ/N2H matches RZ/T2H, describe it using an
RZ/N2H specific compatible string with the RZ/T2H compatible as fallback.

"Including fixes from Bluetooth, wireless and netfilter.
Craziness continues with no end in sight. Even discounting the driver
revert this is a pretty huge PR for standards of the previous era. I'd
speculate - we haven't seen the worst of it, yet. Good news, I guess,
is that so far we haven't seen many (any?) cases of "AI reported a
bug, we fixed it and a real user regressed".
Current release - fix to a fix:
- Bluetooth: btmtk: accept too short WMT FUNC_CTRL events
- vsock/virtio: relax the recently added memory limit a little
Current release - regressions:
- IB/IPoIB: make sure IB drivers always use async set_rx_mode since
some (mlx5) are now required to use it due to locking changes
Previous releases - regressions:
- udp: fix UDP length on last GSO_PARTIAL segment
- af_unix: fix UAF read of tail->len in unix_stream_data_wait()
- tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction
- mlx5e: fix unlocked writing to ICOSQ, breaking AF_XDP
Previous releases - always broken:
- tap: fix stack info leak in tap_ioctl() SIOCGIFHWADDR
- ipv4: raw: reject IP_HDRINCL packets with ihl < 5
- Bluetooth: a lot of locking and concurrency fixes (as always)
- batman-adv (mesh wireless networking): a lot of random fixes for

Pull RISC-V fixes from Paul Walmsley:
"Relatively low-impact fixes. Probably the most notable one is that we
no longer ask the monitor-mode firmware to delegate misaligned access
handling to the kernel by default, since the kernel code needs
significant improvement to match the functionality of the firmware.
This change avoids functional problems at some cost in performance,
but shouldn't affect any system with misaligned access handling in
hardware.
- Disable satp register probing when no5lvl is specified on the
kernel command line
- Fix a CFI-related issue with the misaligned access speed
measurement code
- Reduce the CFI shadow stack size limit from 4GB to 2GB (following
ARM64 GCS)
- Prevent the kernel from requesting delegation of misaligned access
faults unless a new Kconfig option, RISCV_SBI_FWFT_DELEGATE_MISALIGNED,
is enabled. This will depend on CONFIG_NONPORTABLE until the
deficiencies of the kernel misaligned access fixup code are fixed
- Fix some potential uninitialized memory accesses in error paths in
compat_riscv_gpr_set() and compat_restore_sigcontext()
- Fix a bug in the RISC-V MIPS vendor errata patching code where a
logical-and was used in place of a bitwise-and
- Drop some unnecessary code in riscv_fill_hwcap_from_isa_string()
- Use macros for isa2hwcap indices in riscv_fill_hwcap(), rather than
open-coding them
- Fix some documentation typos (one affecting 'make htmldocs')"

The hwmon sysfs naming convention uses
temp[1-*]_input for temperature channels.
Documentation/hwmon/sy7636a-hwmon.rst currently documents
temp0_input, while the driver uses the standard hwmon
temperature channel interface.
Update the documentation to use temp1_input.

The threat-model document says that only users with CAP_SYS_ADMIN can carry
out a number of admin-level tasks, but there are numerous capabilities that
can confer that sort of power. Generalize the text slightly to make it
clear that CAP_SYS_ADMIN is not the only all-powerful capability.

Rather than make readers search for this document, just a link to it where
it is referenced.
(While I was at it, I removed the unused and unneeded _threatmodel label
from the top of threat-model.rst).
