[PATCH v3 0/3] rust, nova-core: PCI Class, Vendor support
Changes since v2:
* Applied changes from Danilo's and Alex's review (thanks!):
* Moved everything possible out of the new define_all_pci_classes!()
and define_all_pci_vendors!() macros.
* Used "impl TryFrom<u32> for Class/Vendor", instead of
.from_u32().
* Made the new DeviceId methods infallible.
* Upgraded DeviceId::from_id() to accept a Vendor struct.
* Changed the names to be a little clearer:
* class_code_raw() --> pci_class_code_raw()
* class_enum() --> pci_class()
* Added doctests for the items that are not yet used in real drivers.
v2 is here:
https://lore.kernel.org/20250818013305.1089446-1-jhubbard at nvidia.com
Changes since v1:
1) Use the pci_device_table for filtering, instead of open-coding
filters in the .probe() callback.
2) Add PCI Class (class, subclass, implementation) and PCI Vendor to
Rust for Linux.
3) Rebased onto the latest nova-next branch, which is here:
https://gitlab.freedesktop.org/drm/nova.git
v1 is here:

[PATCH v3 1/3] rust: pci: provide access to PCI Class, subclass, implementation values
Allow callers to write Class::STORAGE_SCSI instead of
bindings::PCI_CLASS_STORAGE_SCSI, for example.
New APIs:
Class::STORAGE_SCSI, Class::NETWORK_ETHERNET, etc.
Class::as_u32()
Class: TryFrom<u32> for Class
Class::MASK_FULL, MASK_CLASS_SUBCLASS
DeviceId::from_class_and_vendor()
Device::pci_class_code_raw(), pci_class()

[PATCH v3 2/3] gpu: nova-core: avoid probing non-display/compute PCI functions
NovaCore has so far been too imprecise about figuring out if .probe()
has found a supported PCI PF (Physical Function). By that I mean:
.probe() sets up BAR0 (which involves a lot of very careful devres and
Device<Bound> details behind the scenes). And then if it is dealing with
a non-supported device such as the .1 audio PF on many GPUs, it fails
out due to an unexpected BAR0 size. We have been fortunate that the BAR0
sizes are different.
Really, we should be filtering on PCI class ID instead. These days I
think we can confidently pick out Nova's supported PF's via PCI class
ID. And if not, then we'll revisit.
The approach here is to filter on "Display VGA" or "Display
3D", which
is how PCI class IDs express "this is a modern GPU's PF".

[PATCH v3 3/3] rust: pci: provide access to PCI Vendor values
This allows callers to write Vendor::SOME_COMPANY instead of
bindings::PCI_VENDOR_ID_SOME_COMPANY.
It also allows removing "use kernel::bindings" entirely from most of
the affected files here.
Apply this to the various Rust for Linux callers who were previously
using bindings::PCI_VENDOR_ID_*.
New APIs:
Vendor::SOME_COMPANY
Vendor::from_u32(), as_u32()
DeviceId::from_class_and_vendor() now takes Vendor type
