It is not neccessary to check for PCI_EXP_TYPE in sriov_init(). There appears to be no reason for the check. Some AMD GPUs have hardware support for grapics SRIOV. If the GPU has a display output then the GPU needs to support Legacy VGA operation. If CLASS_CODE = VGA then the device should have a Port Type = Legacy EndPoint. Therefore in order to enable SRIOV on a GPU with a display output, LEGACY_END_POINT is supported as a valid Port Type by removing the check for Port Type. Patch is also logged in Bugzilla #112221 Signed-off-by: Kelly Zytaruk <kelly.zytaruk@amd.com> --- drivers/pci/iov.c | 4 ---- 1 file changed, 4 deletions(-)
