2025-09-13gpu: nova-core: firmware: process and prepare the GSP firmwareAlexandre Courbot1-17/+0
The GSP firmware is a binary blob that is verified, loaded, and run by the GSP bootloader. Its presentation is a bit peculiar as the GSP bootloader expects to be given a DMA address to a 3-levels page table mapping the GSP firmware at address 0 of its own address space. Prepare such a structure containing the DMA-mapped firmware as well as the DMA-mapped page tables, and a way to obtain the DMA handle of the level 0 page table. Then, move the GSP firmware instance from the `Firmware` struct to the `start_gsp` method since it doesn't need to be kept after the GSP is booted. As we are performing the required ELF section parsing and radix3 page table building, remove these items from the TODO file.

2025-08-26drm: Add a vendor-specific recovery method to drm device wedged ueventRiana Tauro1-7/+40
Address the need for a recovery method (firmware flash on Firmware errors) introduced in the later patches of Xe KMD. Whenever XE KMD detects a firmware error, a firmware flash is required to recover the device to normal operation. The initial proposal to use 'firmware-flash' as a recovery method was not applicable to other drivers and could cause multiple recovery methods specific to vendors to be added. To address this a more generic 'vendor-specific' method is introduced, guiding users to refer to vendor specific documentation and system logs for detailed vendor specific recovery procedure. Add a recovery method 'WEDGED=vendor-specific' for such errors. Vendors must provide additional recovery documentation if this method is used. It is the responsibility of the consumer to refer to the correct vendor specific documentation and usecase before attempting a recovery. For example: If driver is XE KMD, the consumer must refer to the documentation of 'Device Wedging' under 'Documentation/gpu/xe/'. v2: fix documentation (Raag) v3: add more details to commit message (Sima, Rodrigo, Raag) add an example script to the documentation (Raag) v4: use consistent naming (Raag) v5: fix commit message v6: add more documentation Cc: André Almeida <andrealmeid@igalia.com> Cc: Christian König <christian.koenig@amd.com> Cc: David Airlie <airlied@gmail.com> Cc: Simona Vetter <simona.vetter@ffwll.ch> Cc: Maxime Ripard <mripard@kernel.org> Signed-off-by: Riana Tauro <riana.tauro@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://lore.kernel.org/r/20250826063419.3022216-3-riana.tauro@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2025-08-15gpu: nova-core: register: add support for relative array registersAlexandre Courbot1-1/+0
Add support for declaring arrays of registers available from a variable base. This is effectively a combination of the relative and array registers features. nova-core does not make much use of this yet, but it will become helpful to have for GSP boot. Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://lore.kernel.org/r/20250718-nova-regs-v2-19-7b6a762aa1cd@nvidia.com Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>
2025-08-15gpu: nova-core: register: redesign relative registersAlexandre Courbot1-1/+0
The relative registers are currently very unsafe to use: callers can specify any constant as the base address for access, meaning they can effectively interpret any I/O address as any relative register. Ideally, valid base addresses for a family of registers should be explicitly defined in the code, and could only be used with the relevant registers This patch changes the relative register declaration from e.g.: register!(CPU_CTL @ +0x0000010, "CPU core control" { 0:0 start as bool, "Start the CPU core"; }); into: register!(CPU_CTL @ CpuCtlBase[0x10], "CPU core control" { 0:0 start as bool, "Start the CPU core"; }); Where `CpuCtlBase` is the name of a ZST used as a parameter of the `RegisterBase<>` trait to define a trait unique to a class of register. This specialized trait is then implemented for every type that provides a valid base address, enabling said types to be passed as the base address provider for the register's I/O accessor methods. This design thus makes it impossible to pass an unexpected base address to a relative register, and, since the valid bases are all known at compile-time, also guarantees that all I/O accesses are done within the valid bounds of the I/O range.
