GPU Detect

Inspect the selected Vulkan device and derive architecture-specific tuning defaults.

The heuristics here convert raw Vulkan device properties into the settings used by DMMV, matmul, and attention dispatch code.

3 exports shown

enum

GpuVendor

pub const GpuVendor = enum

GPU vendor and architecture buckets used by ZINC's tuning heuristics.

struct

pub const GpuConfig = struct

Auto-detected GPU capabilities and derived tuning parameters.

method

pub fn nameSlice(self: *const GpuConfig) []const u8

Return the device name as a byte slice covering only the populated prefix.

A slice of `device_name[0..device_name_len]`; no null terminator or padding included.

method

pub fn log_info(self: *const GpuConfig) void

Log the detected GPU name, vendor, memory, wave size, cooperative-matrix support, and all derived tuning parameters at info level.

function

pub fn detect(instance: *const Instance) GpuConfig

Inspect Vulkan device properties and derive runtime tuning defaults.

instance: Active Vulkan instance whose selected physical device should be classified.

A GpuConfig populated from Vulkan limits plus ZINC-specific vendor heuristics.

The classification is heuristic and intentionally biased toward sensible defaults rather than exact SKU detection.
