* NV_MEMORY_VIRTUAL_ALLOCATION_PARAMS
|
|
*
|
|
* Allocation params for NV01_MEMORY_VIRTUAL.
|
|
*
|
|
* NV01_MEMORY_SYSTEM_DYNAMIC is an alias for NV01_MEMORY_VIRTUAL. This
|
|
* was traditionally allocated with RmAllocMemory64(). The default GPU
|
|
* virtual address space is used, and the limit of this address space is
|
|
* returned in limit. The NV01_MEMORY_SYSTEM_DYNAMIC handle can be
|
|
* passed to RmAllocContextDma2() with an offset/limit. The context dma
|
|
* handle can then be used as the hDma handle for RmMapMemoryDma.
|
|
*
|
|
* This behavior is maintained in the RM compatibility shim.
|
|
*
|
|
* NV01_MEMORY_VIRTUAL replaces this behavior with a single object.
|
|
*
|
|
* hVASpace - if hVASpace is NV01_NULL_OBJECT the default GPU VA space is
|
|
* selected. Alternatively a FERMI_VASPACE_A handle may be specified.
|
|
*
|
|
* The NV_MEMORY_VIRTUAL_SYSMEM_DYNAMIC_HVASPACE is used for by the
|
|
* compatibility layer to emulate NV01_MEMORY_SYSTEM_DYNAMIC semantics.
|
|
*
|
|
* offset - An offset into the virtual address space may be specified. This
|
|
* will limit range of the GPU VA returned by RmMapMemoryDma to be
|
|
* above offset.
|
|
*
|
|
* limit - When limit is zero the maximum limit used. If a non-zero limit
|
|
* is specified then it will be used. The final limit is returned.
