From d9426c3d9b4e91dda4f1f1684f9296762fafe0de Mon Sep 17 00:00:00 2001 From: Le Ma Date: Mon, 20 Dec 2021 16:06:25 +0800 Subject: drm/amdgpu: add bitmask to iterate vmhubs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As the layout of VMHUB definition has been changed to cover multiple XCD/AID case, the original num_vmhubs is not appropriate to do vmhub iteration any more. Drop num_vmhubs and introduce vmhubs_mask instead. v2: switch to the new VMHUB layout v3: use DECLARE_BITMAP to define vmhubs_mask Signed-off-by: Le Ma Reviewed-by: Christian König Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c') diff --git a/drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c b/drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c index fb2ac31cbba7..3453f1c0e066 100644 --- a/drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c +++ b/drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c @@ -364,7 +364,7 @@ static int gmc_v11_0_flush_gpu_tlb_pasid(struct amdgpu_device *adev, &queried_pasid); if (ret && queried_pasid == pasid) { if (all_hub) { - for (i = 0; i < adev->num_vmhubs; i++) + for_each_set_bit(i, adev->vmhubs_mask, AMDGPU_MAX_VMHUBS) gmc_v11_0_flush_gpu_tlb(adev, vmid, i, flush_type); } else { @@ -779,7 +779,8 @@ static int gmc_v11_0_sw_init(void *handle) case IP_VERSION(11, 0, 2): case IP_VERSION(11, 0, 3): case IP_VERSION(11, 0, 4): - adev->num_vmhubs = 2; + set_bit(AMDGPU_GFXHUB(0), adev->vmhubs_mask); + set_bit(AMDGPU_MMHUB0(0), adev->vmhubs_mask); /* * To fulfill 4-level page support, * vm size is 256TB (48bit), maximum size, -- cgit
