Struct Config

Configuration for GpuAllocator

Fields

dedicated_threshold: u64

Size in bytes of request that will be served by dedicated memory object. This value should be large enough to not exhaust memory object limit and not use slow memory object allocation when it is not necessary.

preferred_dedicated_threshold: u64

Size in bytes of request that will be served by dedicated memory object if preferred. This value should be large enough to not exhaust memory object limit and not use slow memory object allocation when it is not necessary.

This won’t make much sense if this value is larger than dedicated_threshold.

transient_dedicated_threshold: u64

Size in bytes of transient memory request that will be served by dedicated memory object. This value should be large enough to not exhaust memory object limit and not use slow memory object allocation when it is not necessary.

This won’t make much sense if this value is lesser than dedicated_threshold.

starting_free_list_chunk: u64

Size in bytes of first chunk in free-list allocator.

final_free_list_chunk: u64

Upper limit for size in bytes of chunks in free-list allocator.

minimal_buddy_size: u64

Minimal size for buddy allocator.

initial_buddy_dedicated_size: u64

Initial memory object size for buddy allocator. If less than minimal_buddy_size then minimal_buddy_size is used instead.

Implementations

impl Config

pub fn i_am_prototyping() -> Self

Returns default configuration.

This is not Default implementation to discourage usage outside of prototyping.

Proper configuration should depend on hardware and intended usage.
But those values can be used as starting point.
Note that they can simply not work for some platforms with lesser memory capacity than today’s “modern” GPU (year 2020).

pub fn i_am_potato() -> Self

Returns default configuration for average sized potato.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Config

fn eq(&self, other: &Config) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Config

impl Eq for Config
