Quoting Niranjana Vishwanathapura (2019-11-22 22:57:21) > Shared Virtual Memory (SVM) allows the programmer to use a single virtual > address space which will be shared between threads executing on CPUs and GPUs. > It abstracts away from the user the location of the backing memory, and hence > simplifies the user programming model. > SVM supports two types of virtual memory allocation methods. > Runtime allocator requires the driver to provide memory allocation and > management interface, like buffer object (BO) interface. > Whereas system allocator makes use of default OS memory allocation and > management support like malloc(). > > This patch series adds both SVM system and runtime allocator support > to i915 driver. > > The patch series includes > - SVM support for both system and runtime allocation. > - Plugin in device memory with the Linux kernel. > - User API advertising SVM capability and configuration by user on per > vm basis. > - User API to bind an address range or a BO with a device page table. > - User API to migrate an address range to device memory. > - Implicit migration by moving pages or BOs back from device to host > memory upon CPU access. > - CPU copy and blitter copy support for migrating the pages/BOs. > - Large page mapping support > - Page table dump support. Link to the IGTs, any selftests? Link to userspace changes?
