[Qemu-devel] [PATCH] 16550A FIFO emulation

[bcanet]

Hi,

This is a small patch I wrote to add 16550A FIFO emulation to QEMU.
The main motivation to write this patch was the slowliness of the QEMU serial 
port when the guest operating system is under high load. 
With the 16450 UART an interrupt is generated for every byte send or received.
With FIFO support fewer interrupt are generated.
If anybody has suggestions to improve the correctness/cleanliness of the 
emulation just tell me.

Best regards
