Gfx11 now we have same values, hence we don't need to differentiate between two
sets , only one set is needed like below.
As below
case IP_VERSION(11, 0, 0):
case IP_VERSION(11, 0, 2):
case IP_VERSION(11, 0, 3):
case IP_VERSION(11, 0, 1):
case IP_VERSION(11, 0, 4):
case IP_VERSION(11, 5, 0):
case IP_VERSION(11, 5, 1):
case IP_VERSION(11, 5, 2):
case IP_VERSION(11, 5, 3):
adev->gfx.me.num_me = 1;
adev->gfx.me.num_pipe_per_me = 1;
adev->gfx.me.num_queue_per_pipe = 1;
adev->gfx.mec.num_mec = 1;
adev->gfx.mec.num_pipe_per_mec = 4;
adev->gfx.mec.num_queue_per_pipe = 4;
#ifdef CONFIG_DRM_AMDGPU_NAVI3X_USERQ
adev->userq_funcs[AMDGPU_HW_IP_GFX] = &userq_mes_funcs;
adev->userq_funcs[AMDGPU_HW_IP_COMPUTE] = &userq_mes_funcs;
#endif
break;
