...cards. It's enough to get the panic screen while running Gnome/Wayland on a GTX 1650. It doesn't support multi-plane or compressed format. Support for other formats and older cards will come later. Tiling is only tested on GTX1650, and might be wrong for other cards.

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
