Subject: [PATCH 03/19] drm/i915: Create stolen memory region from local memory
Date: Mon, 12 Apr 2021 10:05:10 +0100 [thread overview]
Message-ID: <20210412090526.30547-4-matthew.auld@intel.com> (raw)
In-Reply-To: <20210412090526.30547-1-matthew.auld@intel.com>
From: CQ Tang <cq.tang@intel.com>
Add "REGION_STOLEN" device info to dg1, create stolen memory
region from upper portion of local device memory, starting
from DSMBASE.
v2:
- s/drm_info/drm_dbg; userspace likely doesn't care about stolen.
- mem->type is only setup after the region probe, so setting the name
as stolen-local or stolen-system based on this value won't work. Split
system vs local stolen setup to fix this.
- kill all the region->devmem/is_devmem stuff. We already differentiate
the different types of stolen so such things shouldn't be needed
anymore.
