| H A D | pci_uart.c | 234938 Thu May 03 03:24:50 MDT 2012 grehan Add 16550 uart emulation as a PCI device. This allows it to be activated as part of the slot config options. The syntax is: -s <slotnum>,uart[,stdio] The stdio parameter instructs the code to perform i/o using stdin/stdout. It can only be used for one instance. To allow legacy i/o ports/irqs to be used, a new variant of the slot command, -S, is introduced. When used to specify a slot, the device will use legacy resources if it supports them; otherwise it will be treated the same as the '-s' option. Specifying the -S option with the uart will first use the 0x3f8/irq 4 config, and the second -S will use 0x2F8/irq 3. Interrupt delivery is awaiting the arrival of the i/o apic code, but this works fine in uart(4)'s polled mode. This code was written by Cynthia Lu @ MIT while an intern at NetApp, with further work from neel@ and grehan@. Obtained from: NetApp |
