gpu: nova-core: bindings: remove unneeded `cfg_attr`

2026-04-07T07:51:39+00:00

These were likely copied from the `bindings` and `uapi` crates, but are unneeded since there are no `cfg(test)`s in the bindings. In addition, the issue that triggered the addition in those crates originally is also fixed in `bindgen` (please see the previous commit). Thus remove them.

gpu: nova-core: apply the one "use" item per line policy to commands.rs

2026-03-10T11:14:32+00:00

As per [1], we need one "use" item per line, in order to reduce merge conflicts. Furthermore, we need a trailing ", //" in order to tell rustfmt(1) to leave it alone. This does that for commands.rs, which is the only file in nova-core that has any remaining instances of the old style.

gpu: nova-core: gsp: derive Zeroable for GspStaticConfigInfo

gpu: nova-core: bindings: derive `MaybeZeroable`

2025-12-16T13:04:25+00:00

Commit 4846300ba8f9 ("rust: derive `Zeroable` for all structs & unions generated by bindgen where possible") automatically derives `MaybeZeroable` for all bindings. This is better than selectively deriving `Zeroable` as it ensures all types that can implement `Zeroable` do. Regenerate the nova-core bindings so they benefit from this, and remove a now unneeded implementation of `Zeroable`.

gpu: nova-core: bindings: add missing explicit padding

2025-12-16T12:59:40+00:00

Explicit padding is needed in order to avoid uninitialized bytes and safely implement `AsBytes`. The `--explicit-padding` of bindgen was omitted by mistake when these bindings were generated.

gpu: nova-core: gsp: Retrieve GSP static info to gather GPU information

2025-11-15T12:54:18+00:00

After GSP initialization is complete, retrieve the static configuration information from GSP-RM. This information includes GPU name, capabilities, memory configuration, and other properties. On some GPU variants, it is also required to do this for initialization to complete.

Add support for sending the SetRegistry command, which is critical to GSP initialization. The RM registry is serialized into a packed format and sent via the command queue. For now only three parameters which are required to boot GSP are hardcoded. In the future a kernel module parameter will be added to enable other parameters to be added.
