[PATCH v1 0/4] PCI/VGA: Improve the default VGA device selection
From: Sui Jingfeng <suijingfeng at loongson.cn>
Currently, the default VGA device selection is not perfect. Potential
problems are:
1) This function is a no-op on non-x86 architectures.
2) It does not take the PCI Bar may get relocated into consideration.
3) It is not effective for the PCI device without a dedicated VRAM Bar.
4) It is device-agnostic, thus it has to waste the effort to

[RFC, drm-misc-next v4 0/9] PCI/VGA: Allowing the user to select the primary video adapter at boot time
From: Sui Jingfeng <suijingfeng at loongson.cn>
On a machine with multiple GPUs, a Linux user has no control over which
one is primary at boot time. This series tries to solve above mentioned
problem by introduced the ->be_primary() function stub. The specific
device drivers can provide an implementation to hook up with this stub by
calling the vga_client_register() function.
Once the
