Crate patina_tianocore 

patina_tianocore

A bridge crate that lets UEFI drivers target TianoCore and Patina through a single API surface — write once, run on either.

The Problem

Today the OEM migration path requires two steps:

1. Port a C UEFI driver to Rust targeting raw TianoCore (r-efi).
2. Rewrite that Rust driver again to use Patina’s component/service model.

The Solution

Define your platform once via the Platform trait:

use patina_tianocore::prelude::*;

pub struct OemPlatform;

impl Platform for OemPlatform {
    fn components(add: &mut impl ComponentAdder) {
        add.component(SmbiosProvider::new(3, 9));
        add.component(MyCustomDriver::default());
    }

    fn configs(add: &mut impl ConfigAdder) {
        add.config(42u32);
    }
}

This single impl drives both runtimes:

• TianoCore today:

  patina_tianocore::driver_entry!(platform: OemPlatform);

• Patina native later (in patina-dxe-core-oem):

  patina_tianocore::impl_component_info!(OemPlatform);
  // That's it — ComponentInfo is auto-generated from Platform.
  // Then add the platform-specific traits:
  impl PlatformInfo for OemPlatform { /* MemoryInfo, CpuInfo, Extractor */ }

The component structs, services, configs — everything inside the Platform methods — transfers with zero changes.

Feature Flags

Feature	Description
tianocore	(default) Back all abstractions with TianoCore / r-efi. The only currently implemented runtime.

A patina-native feature for the Patina-native runtime will be added when the corresponding code paths land.

Entry-point macro for TianoCore DXE drivers.

logger

Minimal UEFI logger that routes log output to ConOut and serial.

Macros

driver_entry

Generates the TianoCore efi_main entry point, global allocator, and panic handler.

impl_component_info

Generates a patina_dxe_core::ComponentInfo impl that delegates to your Platform impl.
