◆ hipCpuDeviceId

#define hipCpuDeviceId ((int)-1)

◆ hipDeviceLmemResizeToMax

#define hipDeviceLmemResizeToMax 0x10

◆ hipDeviceMallocDefault

#define hipDeviceMallocDefault 0x0

◆ hipDeviceMallocFinegrained

#define hipDeviceMallocFinegrained 0x1

Memory is allocated in fine grained region of device.

◆ hipDeviceMallocUncached

#define hipDeviceMallocUncached 0x3

Memory allocated will be uncached.

◆ hipDeviceMapHost

#define hipDeviceMapHost 0x8

◆ hipDeviceScheduleAuto

#define hipDeviceScheduleAuto 0x0

Automatically select between Spin and Yield.

◆ hipDeviceScheduleBlockingSync

#define hipDeviceScheduleBlockingSync 0x4

◆ hipDeviceScheduleMask

#define hipDeviceScheduleMask 0x7

◆ hipDeviceScheduleSpin

#define hipDeviceScheduleSpin 0x1

Dedicate a CPU core to spin-wait. Provides lowest latency, but burns a CPU core and may consume more power.

◆ hipDeviceScheduleYield

#define hipDeviceScheduleYield 0x2

Yield the CPU to the operating system when waiting. May increase latency, but lowers power and is friendlier to other threads in the system.

◆ hipEventBlockingSync

#define hipEventBlockingSync 0x1

Waiting will yield CPU. Power-friendly and usage-friendly but may increase latency.

◆ hipEventDefault

#define hipEventDefault 0x0

Default flags.

◆ hipEventDisableSystemFence

#define hipEventDisableSystemFence 0x20000000

Disable performing a system scope sequentially consistent memory fence when the event transitions from recording to recorded. This can be used for events that are only being used to measure timing, and do not require the event inspection operations (see hipEventSynchronize, hipEventQuery, and hipEventElapsedTime) to synchronize-with the work on which the recorded event (see hipEventRecord) is waiting. On some AMD GPU devices this can improve the accuracy of timing measurements by avoiding the cost of cache writeback and invalidation, and the performance impact of those actions on the execution of following work.

◆ hipEventDisableTiming

#define hipEventDisableTiming 0x2

Disable event's capability to record timing information. May improve performance.

◆ hipEventInterprocess

#define hipEventInterprocess 0x4

Event can support IPC. hipEventDisableTiming also must be set.

◆ hipEventReleaseToDevice

#define hipEventReleaseToDevice 0x40000000

Use a device-scope release when recording this event. This flag is useful to obtain more precise timings of commands between events. The flag is a no-op on CUDA platforms.

◆ hipEventReleaseToSystem

#define hipEventReleaseToSystem 0x80000000

Use a system-scope release when recording this event. This flag is useful to make non-coherent host memory visible to the host. The flag is a no-op on CUDA platforms.

◆ hipExtAnyOrderLaunch

#define hipExtAnyOrderLaunch 0x01

AnyOrderLaunch of kernels.

◆ hipExternalMemoryDedicated

#define hipExternalMemoryDedicated 0x1

◆ hipExtHostRegisterCoarseGrained

#define hipExtHostRegisterCoarseGrained 0x8

Coarse Grained host memory lock.

◆ hipHostMallocCoherent

#define hipHostMallocCoherent 0x40000000

Allocate coherent memory. Overrides HIP_COHERENT_HOST_ALLOC for specific allocation.

◆ hipHostMallocDefault

#define hipHostMallocDefault 0x0

Default pinned memory allocation on the host.

◆ hipHostMallocMapped

#define hipHostMallocMapped 0x2

Map the allocation into the address space for the current device. The device pointer can be obtained with hipHostGetDevicePointer.

◆ hipHostMallocNonCoherent

#define hipHostMallocNonCoherent 0x80000000

Allocate non-coherent memory. Overrides HIP_COHERENT_HOST_ALLOC for specific allocation.

◆ hipHostMallocNumaUser

Host memory allocation will follow numa policy set by user.

Note: This numa allocation flag is applicable on Linux, under development on Windows.

◆ hipHostMallocPortable

#define hipHostMallocPortable 0x1

Memory is considered allocated by all contexts.

◆ hipHostMallocWriteCombined

#define hipHostMallocWriteCombined 0x4

Allocates the memory as write-combined. On some system configurations, write-combined allocation may be transferred faster across the PCI Express bus, however, could have low read efficiency by most CPUs. It's a good option for data tranfer from host to device via mapped pinned memory.

◆ hipHostRegisterDefault

#define hipHostRegisterDefault 0x0

Memory is Mapped and Portable.

◆ hipHostRegisterIoMemory

#define hipHostRegisterIoMemory 0x4

Not supported.

◆ hipHostRegisterMapped

#define hipHostRegisterMapped 0x2

Map the allocation into the address space for the current device. The device pointer can be obtained with hipHostGetDevicePointer.

◆ hipHostRegisterPortable

#define hipHostRegisterPortable 0x1

Memory is considered registered by all contexts.

◆ hipHostRegisterReadOnly

#define hipHostRegisterReadOnly 0x08

This flag is ignored On AMD devices.

◆ hipInvalidDeviceId

#define hipInvalidDeviceId ((int)-2)

◆ hipMallocSignalMemory

#define hipMallocSignalMemory 0x2

Memory represents a HSA signal.

◆ hipMemAttachGlobal

#define hipMemAttachGlobal 0x01

Memory can be accessed by any stream on any device

◆ hipMemAttachHost

#define hipMemAttachHost 0x02

Memory cannot be accessed by any stream on any device.

◆ hipMemAttachSingle

#define hipMemAttachSingle 0x04

Memory can only be accessed by a single stream on the associated device.

◆ hipOccupancyDefault

#define hipOccupancyDefault 0x00

◆ hipOccupancyDisableCachingOverride

#define hipOccupancyDisableCachingOverride 0x01

◆ hipStreamDefault

#define hipStreamDefault 0x00

Default stream creation flags. These are used with hipStreamCreate().

◆ hipStreamNonBlocking

#define hipStreamNonBlocking 0x01

Stream does not implicitly synchronize with null stream.

◆ hipStreamPerThread

#define hipStreamPerThread ((hipStream_t)2)

Implicit stream per application thread.

◆ hipStreamWaitValueAnd

#define hipStreamWaitValueAnd 0x2

◆ hipStreamWaitValueEq

#define hipStreamWaitValueEq 0x1

◆ hipStreamWaitValueGte

#define hipStreamWaitValueGte 0x0

◆ hipStreamWaitValueNor

#define hipStreamWaitValueNor 0x3
