Member Enumeration Documentation

enum gtpin::GtMemoryAddrModel::ADDR_TYPE

Types of memory surfaces / memory address models.

See also:

gfxspecs Index/57222 and Index/44800

Note:

ADDR_TYPE does not distinguish between A32 and A64 stateless models

Enumerator:

BTS_IDX_MIN	Min. Binding Table State Index.
BTS_IDX_MAX	Max. Binding Table State Index.
SS	Surface State address.
BSS	Bindless Surface State address.
SLM	Shared Local Memory address.
STATELESS	Stateless Coherent Memory address.
STATELESS_NC	Stateless Non-Coherent Memory address.
ADDR_TYPE_MAX	Max. valid value of this type.

Constructor & Destructor Documentation

constexpr gtpin::GtMemoryAddrModel::GtMemoryAddrModel	(	uint32_t	bti,
		bool	isA64 = true
	)		[inline]

Construct address model for the address type, specified by Binding Table Index, or a valid ADDR_TYPE value.

Parameters:

[in]	bti	Binding Table Index, or any valid ADDR_TYPE value
[in]	isA64	True for a stateless A64 address model, false otherwise. This parameter is ignored if 'bti' unambiguously specifies a non-stateless model
