Subject: [PATCH v1 0/3] GPU memory aligned
Date: Tue, 4 Jan 2022 01:47:18 +0000	[thread overview]
Message-ID: <20220104014721.1799-1-eagostini@nvidia.com> (raw)

From: Elena Agostini <eagostini@nvidia.com>

Applications may need to allocate GPU memory buffers
with memory address aligned to some value
(e.g. page size).

Similarly to the rte_malloc function, aligned size
can be provided as input to rte_gpu_mem_alloc.

This set of patches implements this functionality
in the gpudev library and the GPU CUDA driver.

  gpudev: mem alloc aligned memory
  app/test-gpudev: test aligned memory allocation
  gpu/cuda: mem alloc aligned memory
