This section describes the deprecated context management functions of HIP runtime API.
hipError_t hipCtxCreate | ( | hipCtx_t * | ctx, |
unsigned int | flags, | ||
hipDevice_t | device | ||
) |
Create a context and set it as current/ default context.

hipError_t hipCtxDestroy | ( | hipCtx_t | ctx | ) |
hipError_t hipCtxDisablePeerAccess | ( | hipCtx_t | peerCtx | ) |
Disable direct access from current context's virtual address space to memory allocations physically located on a peer context.Disables direct access to memory allocations in a peer context and unregisters any registered allocations.
Returns hipErrorPeerAccessNotEnabled if direct access to memory on peerDevice has not yet been enabled from the current device.
[in] | peerCtx |
hipError_t hipCtxEnablePeerAccess | ( | hipCtx_t | peerCtx, |
unsigned int | flags | ||
) |
Enables direct access to memory allocations in a peer context.
Memory which already allocated on peer device will be mapped into the address space of the current device. In addition, all future memory allocations on peerDeviceId will be mapped into the address space of the current device when the memory is allocated. The peer memory remains accessible from the current device until a call to hipDeviceDisablePeerAccess or hipDeviceReset.

int * | apiVersion | ||
) |
Returns the approximate HIP api version.
[in] | ctx | Context to check |
[out] | apiVersion |
hipError_t hipCtxGetCacheConfig | ( | hipFuncCache_t * | cacheConfig | ) |
Set Cache configuration for a specific function.
[out] | cacheConfiguration |
hipError_t hipCtxGetCurrent | ( | hipCtx_t * | ctx | ) |
Get the handle of the current/ default context.
[out] | ctx |
hipError_t hipCtxGetDevice | ( | hipDevice_t * | device | ) |
Get the handle of the device associated with current/default context.
[out] | device |
hipError_t hipCtxGetFlags | ( | unsigned int * | flags | ) |
hipError_t hipCtxGetSharedMemConfig | ( | hipSharedMemConfig * | pConfig | ) |
