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

The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in
