From bdf84a80e0ce5f60f4f41a27b4cf74bcfabcea56 Mon Sep 17 00:00:00 2001 From: Joseph Greathouse Date: Tue, 14 Jan 2020 10:05:21 -0500 Subject: drm/amdgpu: Create generic DF struct in adev The only data fabric information the adev struct currently contains is a function pointer table. In the near future, we will be adding some cached DF information into adev. As such, this patch creates a new amdgpu_df struct for adev. Right now, it only containst the old function pointer table, but new stuff will be added soon.

The gfx core's caches also need to know this mapping, but the hash settings for these these caches is set by the driver. This change queries the DF to understand how the VBIOS configured DF, then matches the TC hash configuration bits to do the same thing. v2: squash in warning fix Signed-off-by: Joseph Greathouse Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/df_v1_7.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/df_v1_7.c') diff --git a/drivers/gpu/drm/amd/amdgpu/df_v1_7.c b/drivers/gpu/drm/amd/amdgpu/df_v1_7.c index 03fdeef568d9..d6aca1c08068 100644 --- a/drivers/gpu/drm/amd/amdgpu/df_v1_7.c +++ b/drivers/gpu/drm/amd/amdgpu/df_v1_7.c @@ -31,6 +31,9 @@ static u32 df_v1_7_channel_number[] = {1, 2, 0, 4, 0, 8, 0, 16, 2}; static void df_v1_7_sw_init(struct amdgpu_device *adev) { + adev->df.hash_status.hash_64k = false; + adev->df.hash_status.hash_2m = false; + adev->df.hash_status.hash_1g = false; } static void df_v1_7_sw_fini(struct amdgpu_device *adev) -- cgit v1.2.3
