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

From: Sui Jingfeng <suijingfeng at loongson.cn> Patch 1,2 and 3 do basic clean up to the vgaarb module. Patch 4 introduce is_boot_device function callback to vga_client_register Sui Jingfeng (4): PCI/VGA: tidy up the code and comment format PCI/VGA: Use unsigned type for the io_state variable PCI/VGA: only deal with VGA class devices PCI/VGA: introduce is_boot_device function

From: Sui Jingfeng <suijingfeng at loongson.cn> To keep consistent with vga_iostate_to_str() function, the third argument of vga_str_to_iostate() function should be 'unsigned int *'.

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
