From 6a42fd6fbf5340968b1fb41bf6a700699ddb5a13 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Tue, 5 Dec 2017 15:23:26 +0100 Subject: [PATCH] drm/amdgpu: implement 2+1 PD support for Raven v3 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of falling back to 2 level and very limited address space use 2+1 PD support and 128TB + 512GB of virtual address space. v2: cleanup defines, rebase on top of level enum v3: fix inverted check in hardware setup Signed-off-by: Christian König Reviewed-and-Tested-by: Chunming Zhou Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h | 6 +++ drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c | 42 +++++++++++++------- drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 26 +++++++++++-- drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c | 49 +++++++++++++++--------- 5 files changed, 89 insertions(+), 35 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 6b296e1fecf2..bbe06e04dcb6 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -540,6 +540,7 @@ struct amdgpu_mc { u64 private_aperture_end;
