Split the per-instance initialization code from vcn_v5_0_1_hw_init() into a new vcn_v5_0_1_hw_init_inst() function. This improves code organization by:
1. Separating the instance-specific initialization logic 2. Making the main init function more readable Signed-off-by: Jesse Zhang <[email protected]> Signed-off-by: Ruili Ji <[email protected]> --- drivers/gpu/drm/amd/amdgpu/vcn_v5_0_1.c | 41 ++++++++++++++++--------- 1 file changed, 27 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/vcn_v5_0_1.c b/drivers/gpu/drm/amd/amdgpu/vcn_v5_0_1.c index 7cb21e2b4eb0..21e48df537bd 100644 --- a/drivers/gpu/drm/amd/amdgpu/vcn_v5_0_1.c +++ b/drivers/gpu/drm/amd/amdgpu/vcn_v5_0_1.c @@ -256,6 +256,31 @@ static int vcn_v5_0_1_sw_fini(struct amdgpu_ip_block *ip_block) return 0; } +static int vcn_v5_0_1_hw_init_inst(struct amdgpu_device *adev, int i) +{ + struct amdgpu_ring *ring; + int vcn_inst; + int r; + + vcn_inst = GET_INST(VCN, i); + ring = &adev->vcn.inst[i].ring_enc[0]; + + if (ring->use_doorbell) + adev->nbio.funcs->vcn_doorbell_range(adev, ring->use_doorbell, + ((adev->doorbell_index.vcn.vcn_ring0_1 << 1) + + 11 * vcn_inst), + adev->vcn.inst[i].aid_id); + + /* Re-init fw_shared, if required */ + vcn_v5_0_1_fw_shared_init(adev, i); + + r = amdgpu_ring_test_helper(ring); + if (r) + return r; + + return 0; +} + /** * vcn_v5_0_1_hw_init - start and test VCN block * @@ -267,7 +292,7 @@ static int vcn_v5_0_1_hw_init(struct amdgpu_ip_block *ip_block) { struct amdgpu_device *adev = ip_block->adev; struct amdgpu_ring *ring; - int i, r, vcn_inst; + int i, r; if (amdgpu_sriov_vf(adev)) { r = vcn_v5_0_1_start_sriov(adev); @@ -285,19 +310,7 @@ static int vcn_v5_0_1_hw_init(struct amdgpu_ip_block *ip_block) if (RREG32_SOC15(VCN, GET_INST(VCN, 0), regVCN_RRMT_CNTL) & 0x100) adev->vcn.caps |= AMDGPU_VCN_CAPS(RRMT_ENABLED); for (i = 0; i < adev->vcn.num_vcn_inst; ++i) { - vcn_inst = GET_INST(VCN, i); - ring = &adev->vcn.inst[i].ring_enc[0]; - - if (ring->use_doorbell) - adev->nbio.funcs->vcn_doorbell_range(adev, ring->use_doorbell, - ((adev->doorbell_index.vcn.vcn_ring0_1 << 1) + - 11 * vcn_inst), - adev->vcn.inst[i].aid_id); - - /* Re-init fw_shared, if required */ - vcn_v5_0_1_fw_shared_init(adev, i); - - r = amdgpu_ring_test_helper(ring); + r = vcn_v5_0_1_hw_init_inst(adev, i); if (r) return r; } -- 2.49.0
