Subject: [PATCH 07/19] drm/i915/fbdev: Use lmem physical addresses for fb_mmap() on discrete
Date: Mon, 12 Apr 2021 10:05:14 +0100	[thread overview]
Message-ID: <20210412090526.30547-8-matthew.auld@intel.com> (raw)
In-Reply-To: <20210412090526.30547-1-matthew.auld@intel.com>

From: Mohammed Khajapasha <mohammed.khajapasha@intel.com>

use local memory io BAR address for fbdev's fb_mmap() operation on
discrete, fbdev uses the physical address of our framebuffer for its
fb_mmap() fn.
