Subject: [PATCH V3 0/3] drm: replace magic numbers
Date: Tue, 12 Nov 2019 11:35:00 -0600 [thread overview]
Message-ID: <20191112173503.176611-1-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.
Since v2:
- Fix a gpu_cfg2 case in amdgpu/si.c that I had missed
- Separate out the functional changes for better bisection (thanks,
Michel!)
- Add #defines in a patch by themselves (so a GPU revert wouldn't break
other potential users)
- Squash all the magic number -> #define changes into one patch
Since v1:
- Add my signed-off-by and Alex's reviewed-by.
Bjorn Helgaas (3):
PCI: Add #defines for Enter Compliance, Transmit Margin
drm: correct Transmit Margin masks
drm: replace numbers with PCI_EXP_LNKCTL2 definitions
