From 77e163147ecb8e6b7290cac6d409d547cb9626be Mon Sep 17 00:00:00 2001
From: Philip Yang <Philip.Yang@amd.com>
Date: Mon, 19 Nov 2018 09:53:43 -0500
Subject: [PATCH 0830/2940] drm/amdgpu: enable paging queue based on FW version
(v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Based SDMA fw version to enable has_page_queue support. Have to move
sdma_v4_0_init_microcode from sw_init to early_init, to load firmware
and init fw_version before set_ring/buffer/vm_pte_funcs use it.
v2: don't enable on vega12, 20 until confirmed
