The `GspHal` trait design is clean: ```rust +pub(super) trait GspHal: Send { + fn boot(&self, ...) -> Result; + fn post_boot(&self, ...) -> Result { Ok(()) } +} ``` The `post_boot` default implementation is smart -- only TU102 needs it (for the sequencer), while GH100 can skip it. The HAL dispatch via static references is efficient: ```rust +pub(super) fn gsp_hal(chipset: Chipset) -> &'static dyn GspHal { + match chipset.arch() { + Architecture::Turing | Architecture::Ampere | Architecture::Ada => tu102::TU102_HAL, + Architecture::Hopper | Architecture::BlackwellGB10x | Architecture::BlackwellGB20x => { + gh100::GH100_HAL + } + } +} ``` The `boot()` signature has `#[allow(clippy::too_many_arguments)]` with 8 parameters. This is a lot, but each parameter is necessary and this is an internal interface. A builder or context struct could reduce the parameter count but would add complexity without clear benefit at this stage. The `boot()` receiver changes from `self: Pin<&mut Self>` to `mut self: Pin<&mut Self>` to enable `self.as_mut()` for pin projection through the HAL -- correct. In `tu102.rs`, the `post_boot` implementation accesses `gsp.libos` and `gsp.cmdq` directly through the `Pin<&mut Gsp>`: ```rust + let seq_params = GspSequencerParams { + ... + libos_dma_handle: gsp.libos.dma_handle(), + ... + }; + GspSequencer::run(&gsp.cmdq, seq_params)?; ``` This works because `libos` is not a pinned field in `Gsp` (only `logs` and `cmdq` are `#[pin]`), so direct field access through `Pin<&mut Gsp>` is fine. Wait -- `cmdq` **is** pinned, so `&gsp.cmdq` through a `Pin<&mut Gsp>` accesses the pinned field by shared reference, which is allowed since `Cmdq` likely implements the necessary access. No blocking issues. --- --- Generated by Claude Code Patch Reviewer
