Re: [PATCH 1/2] drm/amdgpu: return the PCIe gen and lanes from the INFO

[Christian König <ckoenig.leichtzumerken@xxxxxxxxx>]

    That stuff is already available as current_link_speed and
    current_link_width in sysfs.
    
    I'm a bit reluctant duplicating this information in the IOCTL
    interface.

For computing PCIe bandwidth in userspace and troubleshooting PCIe
bandwidth issues.

For example, my Navi21 has been limited to PCIe gen 1 and this is
the first time I noticed it after 2 years.

Note that this intentionally fills a hole and padding
in drm_amdgpu_info_device.
