Merge tag 'drm-rust-next-2026-08-08' of https://gitlab.freedesktop.org/drm/rust/kernel into drm-nextDRM 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.[1] https://github.com/ttabi/linux-firmware-novaSigned-off-by: Dave Airlie From: "Danilo Krummrich" Link: https://patch.msgid.link/DKJQQUOS0PVO.3JPR3MYK4PDVZ@kernel.org List of files: /linux/drivers/gpu/nova-core/vgpu.rs

Wed, 22 Jul 2026 09:39:13 +0200

gpu: nova-core: reserve vGPU WPR2 heapGSP-RM needs a larger WPR2 heap when booting in vGPU mode. The heap sizeis firmware-dependent, so it should come from the generated firmwarebindings instead of being open-coded in nova-core.Pass the detected vGPU state into the framebuffer layout calculation. Keepbaremetal boots on the existing heap sizing path, and use the 570.144vGPU default heap binding only when vGPU is enabled. The same state matchalso sets the VF partition count, so disabled and invalid 0/1-VF states donot enter the vGPU heap path.Cc: Alexandre Courbot Signed-off-by: Zhi Wang Reviewed-by: Alexandre Courbot Link: https://patch.msgid.link/20260722073913.1807677-7-zhiw@nvidia.com[ Use checked arithmetic to calculate wpr2_heap_addr. - Danilo ]Signed-off-by: Danilo Krummrich List of files: /linux/drivers/gpu/nova-core/vgpu.rs

Wed, 22 Jul 2026 09:39:12 +0200

gpu: nova-core: set RMSetSriovMode for vGPUThe GSP registry setup needs to advertise SR-IOV mode when nova-core bootsGSP for an enabled vGPU configuration. Without the registry entry, GSP-RMis not told to initialize in the mode required by NVIDIA vGPU.Append RMSetSriovMode to the SetRegistry command when the vGPU statedetected before GSP boot is enabled. Keep the existing registry entriesunchanged for non-vGPU boots.Cc: Alexandre Courbot Signed-off-by: Zhi Wang Reviewed-by: Alexandre Courbot Link: https://patch.msgid.link/20260722073913.1807677-6-zhiw@nvidia.comSigned-off-by: Danilo Krummrich List of files: /linux/drivers/gpu/nova-core/vgpu.rs

Wed, 22 Jul 2026 09:39:11 +0200

gpu: nova-core: detect and store vGPU stateGSP boot needs a stable view of vGPU state before it starts building theboot-time data structures that depend on SR-IOV and firmware policy. Thatstate must be derived once from the PCI VF count and the FSP PRC vGPU modeknob before booting GSP.Add VgpuManager to detect and retain the vGPU state during GPUconstruction. Keep the manager separate from the detected state becauselater vGPU milestones will add vGPU resources and lifecycle state to it.Keep the vGPU capability gate local to the vGPU module with per-chip HALmodules. Treat failures to detect the optional vGPU state as disabled sothey do not prevent a bare-metal probe, and log both the failure and thedetected state where the manager is constructed.Cc: Alexandre Courbot Signed-off-by: Zhi Wang Reviewed-by: Alexandre Courbot Link: https://patch.msgid.link/20260722073913.1807677-5-zhiw@nvidia.comSigned-off-by: Danilo Krummrich List of files: /linux/drivers/gpu/nova-core/vgpu.rs
