Merge tag 'drm-rust-next-2026-03-30' of https://gitlab.freedesktop.org/drm/rust/kernel into drm-next

DRM Rust changes for v7.1-rc1

- DMA:
- Rework the DMA coherent API: introduce Coherent<T> as a generalized
container for arbitrary types, replacing the slice-only
CoherentAllocation<T>. Add CoherentBox for memory initialization
before exposing a buffer to hardware (converting to Coherent when
ready), and CoherentHandle for allocations without kernel mapping.

- Add Coherent::init() / init_with_attrs() for one-shot initialization
via pin-init, and from-slice constructors for both Coherent and
CoherentBox

- Add uaccess write_dma() for copying from DMA buffers to userspace
and BinaryWriter support for Coherent<T>

- DRM:
- Add GPU buddy allocator abstraction

- Add DRM shmem GEM helper abstraction

- Allow drm::Device to dispatch work and delayed work items to driver
private data

- Add impl_aref_for_gem_obj!() macro to reduce GEM refcount
boilerplate, and introduce DriverObject::Args for constructor
context

- Add dma_resv_lock helper and raw_dma_resv() accessor on GEM objects

- Clean up imports across the DRM module

- I/O:
- Merged via a signed tag from the driver-core tree: register!() macro
and I/O infrastructure improvements (IoCapable refactor, RelaxedMmio
wrapper, IoLoc trait, generic accessors, write_reg /
LocatedRegister)

- Nova (Core):
- Fix and harden the GSP command queue: correct write pointer
advancing, empty slot handling, and ring buffer indexing; add mutex
locking and make Cmdq a pinned type; distinguish wait vs no-wait
commands

- Add support for large RPCs via continuation records, splitting
oversized commands across multiple queue slots

- Simplify GSP sequencer and message handling code: remove unused
trait and Display impls, derive Debug and Zeroable where applicable,
warn on unconsumed message data

- Refactor Falcon firmware handling: create DMA objects lazily, add
PIO upload support, and use the Generic Bootloader to boot FWSEC on
Turing

- Convert all register definitions (PMC, PBUS, PFB, GC6, FUSE, PDISP,
Falcon) to the kernel register!() macro; add bounded_enum macro to
define enums usable as register fields

- Migrate all DMA usage to the new Coherent, CoherentBox, and
CoherentHandle APIs

- Harden firmware parsing with checked arithmetic throughout FWSEC,
Booter, RISC-V parsing paths

- Add debugfs support for reading GSP-RM log buffers; replace
module_pci_driver!() with explicit module init to support
module-level debugfs setup

- Fix auxiliary device registration for multi-GPU systems

- Various cleanups: import style, firmware parsing refactoring,
framebuffer size logging

- Rust:
- Add interop::list module providing a C linked list interface

- Extend num::Bounded with shift operations, into_bool(), and const
get() to support register bitfield manipulation

- Enable the generic_arg_infer Rust feature and add EMSGSIZE error
code

- Tyr:
- Adopt vertical import style per kernel Rust guidelines

- Clarify driver/device type names and use DRM device type alias
consistently across the driver

- Fix GPU model/version decoding in GpuInfo

- Workqueue:
- Add ARef<T> support for work and delayed work

gpu: nova-core: convert falcon registers to kernel register macro

Convert all PFALCON, PFALCON2 and PRISCV registers to use the kernel's
register macro and update the code accordingly.

Because they rely on the same types to implement relative registers,
they need to be updated in lockstep.

nova-core's local register macro is now unused, so remove it.

gpu: nova-core: use the Generic Bootloader to boot FWSEC on Turing

On Turing and GA100, a new firmware image called the Generic Bootloader
(gen_bootloader) must be used to load FWSEC into Falcon memory. The
driver loads the generic bootloader into Falcon IMEM, passes a
descriptor that points to FWSEC using DMEM, and then boots the generic
bootloader. The bootloader will then load FWSEC into IMEM and boot it.
