* gpu: nvgpu: Clear PTE ref after freeingTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | When clearing sparse buffers, pte->ref must be cleared once the PTE is freed.

* gpu: nvgpu: gm20b: Fix pm refs in VPR info fetchArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | The code took reference to gk20a by using gk20a_busy_noresume(). This function takes pm runtime reference only to the GPU, however, the code dropped the reference by calling gk20a_idle() which also drops the reference to the platform dependencies (host1x). This patch modifies gm20b_mm_mmu_vpr_info_fetch_wait() to drop only the GPU reference.

| | | | | | | | | | | | | | Gk20a unmaps the addresses binding to dummy page to clear sparse. On Gm20b, we need to free the allocated page table entry for sparse memory.
