Subject: [PATCH v9 55/60] PCI, x86: Allocate from high in available window for MMIO
Date: Thu, 10 Dec 2015 21:06:51 -0800 [thread overview]
Message-ID: <1449810416-2950-56-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1449810416-2950-1-git-send-email-yinghai@kernel.org>
Current code just use aligned start from avialable window, that could waste
big alignment from start.
We can align to the end from avialable window, so will save
start with big align to others: like second try for pref mmio
after first try already have non-pref assigned.

So we allocate high for 0a:00.0 and etc, and leave low range like 0xb0000000 to
0b:04.0 and 0f:00.0
