DRM Rust changes for v7.3-rc1

- I/O (shared from driver-core tree via signed tag rust-io-7.3-rc1

Merge tag 'drm-rust-next-2026-08-08' of https://gitlab.freedesktop.org/drm/rust/kernel into drm-next

DRM Rust changes for v7.3-rc1

- I/O (shared from driver-core tree via signed tag rust-io-7.3-rc1):

- Rework of I/O types: make I/O regions typed (with a
dynamically-sized Region type for the existing untyped case), create
view types representing subregions of a mapped I/O region, and add
io_project!() for safely creating subviews.

- Split Io into a base trait (IoBase) and an extension trait (Io) with
a blanket implementation, preventing implementers from overriding
provided methods that unsafe code relies on.

- Add a SysMem backend for shared system memory with volatile access,
and make Coherent implement Io via an I/O view type. Add copying
methods (memcpy_{from,to}io).

- Replace dma_read!/dma_write! with io_read!/io_write!; drop the old
macros.

- DRM:

- RegistrationGuard and RegistrationData:
- Rework DeviceContext typestates: rename Uninit to Normal, add an
Ioctl context, restrict AlwaysRefCounted to Normal for both Device
and GEM Object, and establish a Deref chain from Registered to
Normal.

- Introduce RegistrationGuard, a guard representing a
drm_dev_enter/exit SRCU critical section that proves the DRM
device is registered, which implies the parent bus device is still
bound.

- Add RegistrationData as a GAT on drm::Driver. The data does not
outlive driver unbind, so it can capture lifetime-annotated device
resources and references. Accessible through the guard via a
closure with HRTB lifetime.

- Wrap ioctl dispatch in RegistrationGuard (returning ENODEV if
unplugged) and pass registration data to handlers.

- Add Driver::ParentDevice associated type.

- Fix unbounded lifetimes in ioctl handler arguments.

- Fix a race in drm_dev_register() where a partial failure allowed
in-flight ioctls to proceed while the error path tore down
resources.

- GEM shmem: add DmaResvGuard helper, vmap functions, and sg_table()
accessor.

- GPUVM: require Send + Sync for the driver's associated data,
implement Send and Sync for GpuVaAlloc and GpuVmBo, add SmContext
lifetime bound, update DriverGpuVm for DeviceContext.

- Nova:

- nova-core / nova-drm cross-crate dependency:
- Build nova-core and nova-drm from drivers/gpu/Makefile for build
ordering, export nova-core Rust symbols for nova-drm. Workaround
until the build system supports Rust cross-crate dependencies
natively.

- GSP boot process consolidation:
- Introduce GspBootContext to bundle common boot parameters,
replacing per-argument threading. Separate context and GPU
lifetimes to support mutable borrows of GPU subdevices.

- Turn FWSEC execution into a HAL method, make FWSEC bootloader
usage a property of the TU102 HAL (GA102+ gets its own instance
with it disabled). Move firmware file selection to the GSP HAL.

- Store the Fsp instance in Gpu (lifetime tied to the GPU, not just
a single boot invocation). Move GSP state and unload bundle into a
pinned subobject for reliable teardown on partial init failure.

- Boot GSP with vGPU enabled:
- Add PRC (Product Reconfiguration Control) protocol to query device
configuration from the FSP. Read vGPU mode, detect and store vGPU
state.
- Set RMSetSriovMode registry entry and reserve the larger WPR2 heap
required when vGPU is enabled.
- Build SetRegistry entries dynamically.

- TLV firmware image format:
- Add a TLV (type-length-value) parser for the new firmware image
format. TLV files use unversioned filenames with a .tlv suffix,
start with "NVFW" magic, and contain tagged blocks with 4-byte
aligned payloads.
- Transition all firmware loading (booter, gsp, gen_bootloader, fsp)
to TLV images.
- Note: this requires a development firmware not in linux-firmware
[1]; this is temporary and serves the transition to r615.

- Hopper/Blackwell fixes and cleanups:
- Correct FRTS vidmem offset calculation, split FbLayout into FSP
and non-FSP versions, fix Blackwell flush address composition, use
absolute FBHUB0 flush registers on Blackwell, use correct sysmem
flush registers on Hopper.
- Harden FSP messaging: limit receive allocation size, catch bogus
queue pointers, ensure DMA allocation lifetimes for FMC boot and
LibOS, wait for RISC-V HALTED on unload.

- I/O projection adoption:
- Use io_project!() for PTE array, message queues, and Falcon DMA
transfer bounds checking.

- Misc:
- Keep unloading if FWSEC-SB fails during Turing/Ampere GSP reset.
- Don't declare booter firmware for FSP chipsets.
- Fix packed registry table size.
- Extract and display usable FB regions from GSP.
- Store bar and dev directly in Falcon, simplifying the API.
- Parse VBIOS structs via zerocopy.
- Convert to kernel bitfield macro, remove local one.
- Move register definitions into sub-modules.
- Add FSP and PRC protocol documentation.

- Tyr:

- Firmware loading and MCU boot:
- Add a generic slot manager for dynamically allocating limited
hardware slots to software seats, with lazy eviction under
contention.
- Add MMU support wrapping the slot manager for address-space slot
allocation, with MAIR-to-MEMATTR translation.
- Add GPU virtual memory (VM) support using drm_gpuvm with ARM64
LPAE Stage 1 page tables and 4KB/2MB page sizes.
- Add a kernel buffer object type for internal driver allocations.
- Add a parser for the Mali CSF firmware binary format.
- Add MCU booting: load, parse, and map firmware sections into VM,
then boot the MCU at probe().

- Cross-subsystem:

- Add faux::Device type with AsBusDevice support. Allow retrieving a
bound Device from a Registration.

- Add device lifetime to IoPageTable.

- Add Vec::zeroed method.

- Add firmware::request_into_buf() to load firmware into a
caller-provided buffer.

- Rename dma_handle to dma_address in the DMA abstraction.

- Change pci_sriov_get_totalvfs() return type to unsigned int; add
Rust helper.
