From afa31cdd8cc6bb04faeed30b2cc30f5e6be888b5 Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Mon, 3 Jul 2017 16:40:44 +0530 Subject: gpu: nvgpu: add support for L3 cache allocation of buffers Add gv11b implementation of gpu_phys_addr() that checks the t19x GMMU attributes struct to determine if L3 allocation should be enabled. If L3 alloc is enabled then a special physical address bit is set. Add flag NVGPU_AS_MAP_BUFFER_FLAGS_L3_ALLOC to struct nvgpu_as_map_buffer_ex_args so that User space can add a hint to allocate buffer in L3 cache Jira GPUT19X-10 Bug 200279508 Change-Id: I1bb9876a670b252980922aa50e3e69b802be137f Signed-off-by: Deepak Nibade Reviewed-on: https://git-master/r/1512602 GVS: Gerrit_Virtual_Submit Reviewed-by: Vijayakumar Subbu --- drivers/gpu/nvgpu/common/mm/gmmu_t19x.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 drivers/gpu/nvgpu/common/mm/gmmu_t19x.c (limited to 'drivers/gpu/nvgpu/common/mm') diff --git a/drivers/gpu/nvgpu/common/mm/gmmu_t19x.c b/drivers/gpu/nvgpu/common/mm/gmmu_t19x.c new file mode 100644 index 00000000..05abec1b --- /dev/null +++ b/drivers/gpu/nvgpu/common/mm/gmmu_t19x.c @@ -0,0 +1,25 @@ +/* + * Copyright (c) 2017, NVIDIA CORPORATION.
