From 193a6144b9612bafde9b4382a221e917496b8601 Mon Sep 17 00:00:00 2001 From: marcel Date: Fri, 28 Apr 2006 21:21:53 +0000 Subject: Rewrite of puc(4). Significant changes are: o Properly use rman(9) to manage resources. This eliminates the need to puc-specific hacks to rman. It also allows devinfo(8) to be used to find out the specific assignment of resources to serial/parallel ports. o Compress the PCI device "database" by optimizing for the common case and to use a procedural interface to handle the exceptions. The procedural interface also generalizes the need to setup the hardware (program chipsets, program clock frequencies). o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by default and non-serdev devices are handled by the bus. o Use the serdev I/F to collect interrupt status and to handle interrupts across ports in priority order. o Sync the PCI device configuration to include devices found in NetBSD and not yet merged to FreeBSD. o Add support for Quatech 2, 4 and 8 port UARTs. o Add support for a couple dozen Timedia serial cards as found in Linux. --- sys/dev/uart/uart_bus_puc.c | 38 +++++++++++++------------------------- 1 file changed, 13 insertions(+), 25 deletions(-) (limited to 'sys/dev/uart') diff --git a/sys/dev/uart/uart_bus_puc.c b/sys/dev/uart/uart_bus_puc.c index 7277df9..dff35b3 100644 --- a/sys/dev/uart/uart_bus_puc.c +++ b/sys/dev/uart/uart_bus_puc.c @@ -1,4 +1,5 @@ /*- + * Copyright (c) 2006 Marcel Moolenaar.
