| * | gpu: nvgpu: fix memory leak in case of failure | Deepak Nibade | 2016-09-01 |
| | | | | | | | | | | | | | | | | | | | | | In __gk20a_alloc_pages(), if we fail to allocate a chunk we free previously allocated chunks in error path But we do not free up the memory reserved in those chunks which could lead to OOM situations Fix this by calling gk20a_free() for each chunk in error path Jira DNVGPU-96 Change-Id: I68aa18d68a5282405016e688c790ccbc0c2a0d69 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1203098 (cherry picked from commit f096bd1675600f4e2fc2d686f2911bb945fbbf0b) Reviewed-on: http://git-master/r/1210952 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> | ||
| * | gpu: nvgpu: Implement a vidmem allocator | Alex Waterman | 2016-08-30 |
| Implement an allocator suitable for managing the video memory on dGPUs. It works by allocating chunks from an underlying buddy allocator and collating the chunks together (similar to what an sgt does in the wider Linux kernel). This handles the ability to get large buffers in potentially fragmented memory. The GMMU can then obviously map the physical vidmem into contiguous GVA spaces.
