gpu: nova-core: firmware: parse `FalconUCodeDescV2` via `zerocopy`

2026-06-09T02:13:23+00:00

Now that we have `zerocopy` support, we can avoid some `unsafe` code. For instance, for `FalconUCodeDescV2`, we can replace the `unsafe impl FromBytes` by safely deriving `zerocopy`'s `FromBytes` and then calling `read_from_prefix`.

gpu: nova-core: move lifetime to `Bar0`

2026-06-03T20:10:51+00:00

Currently Nova code uses `&'a Bar0` a lot. This is `&'a Mmio`, where `Mmio` represents an owned MMIO region; this type only exists as a target for `Deref` so `Bar` and `IoMem` can share code and should be avoided to be named directly. The upcoming I/O projection series would make `Io` trait much simpler to implement, and thus the owned MMIO type would be removed in favour of direct `Io` implementation on `Bar` and `IoMem`. Add lifetime parameter to `Bar0<'a>` and change it to be alias of `&'a pci::Bar<'a, ..>`. This also prepares Nova core so that when I/O projection series land, this could be changed to using a MMIO view type directly which avoids double indirection.

gpu: nova-core: vbios: remove unnecessary fields in PciRomHeader

2026-05-25T18:18:08+00:00

Remove unnecessary fields in PciRomHeader. This allows a simplification to use `FromBytes` instead of reading fields piecemeal. A lot of these checks were redundant as well since it checks the size of the `data` first in `BiosImage`.

gpu: nova-core: vbios: use single logical block for the FWSEC section

2026-05-25T18:18:08+00:00

Currently, FWSEC takes the first image and the last image. Treat the first FWSEC image and all following image data as one logical block for building the final FWSEC image. This avoids explicitly tracking two FWSEC images. Signed-off-by: Eliot Courtney Link: https://patch.msgid.link/20260525-fix-vbios-v5-16-e5e455251537@nvidia.com Signed-off-by: Danilo Krummrich
