From 1dde0ea95b782425b95455d487cb44991525a1d1 Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Tue, 20 Nov 2018 21:00:29 -0500 Subject: drm/amdkfd: Add DMABuf import functionality This is used for interoperability between ROCm compute and graphics APIs. It allows importing graphics driver BOs into the ROCm SVM address space for zero-copy GPU access. The API is split into two steps (query and import) to allow user mode to manage the virtual address space allocation for the imported buffer.
