Subject: [PATCH 0/2] drm: replace magic nuumbers
Date: Thu, 7 Nov 2019 16:20:45 -0600 [thread overview]
Message-ID: <20191107222047.125496-1-helgaas@kernel.org> (raw)
From: Bjorn Helgaas <bhelgaas@google.com>
amdgpu and radeon do a bit of mucking with the PCIe Link Control 2
register, some of it using hard-coded magic numbers. The idea here is to
replace those with #defines.
I haven't signed off on these because the first one actually changes the
bits involved because the existing code looks like it might have a typo.
But I have no way to know for sure.
I don't intend the Target Link Speed patch to change anything, so it should
be straightforward to review.
