* Fix interrupt handling. It started off broken and grew worse over time.marcel2009-12-111-46/+62
| | | | | | | | | | | | | | | The rewrite of the interrupt handler includes: o loop until all pending interrupts are handled. This closes a race condition. o count the number of interrupt sources we handled so that we can properly return FILTER_HANDLED or FILTER_STRAY when we break out of the loop. o When matching the interrupt source to the devices that have that source pending, check only from the set of devices we found to have a pending interrupt.

* Rewrite of puc(4). Significant changes are:marcel2006-04-281-486/+583
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | via the DEFAULTS kernel configs. This allows folks to turn it that option off in the kernel configs if desired without having to hack the source. This is especially useful since PUC_FASTINTR hangs the kernel boot on my ultra60 which has two uart(4) devices hung off of a puc(4) device. I did not enable PUC_FASTINTR by default on powerpc since powerpc does not currently allow sharing of INTR_FAST with non-INTR_FAST like the other archs.

* - sparc64/fhc/fhc.c:marius2005-03-041-9/+0
| | | | | | | | | | | | | | | | | Change fhc(4) to use IRQ numbers instead of RIDs for allocating the IRQs of children. This works similar to e.g. sbus(4), i.e. add the IRQ resources as fully specified to the resource lists of the children, allocate them like normal. When establishing the interrupt search the interrupt maps of the children for a matching INO to determine which map we need to write the fully specified interrupt number to and to enable the mapping (before the RID was used to indicate which interrupt map to use). - dev/puc/puc.c: Revert rev. 1.38, with the above change fhc(4) no longer needs special treatment for allocating IRQs.

* Enhance puc(4) to support uart(4). This includes:marcel2003-09-061-69/+80
| | | | | | | | | | | | | | | | | | | | | | | | | o Introduce PUC_PORT_TYPE_UART so that we can attach to uart(4), o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530) to handle different hardware and determine resource sizes. o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both are used by uart(4) to get sufficient information to talk to the HW. o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O if I/O port space cannot be allocated, or vice versa. o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching to sio(4) fails (due to not having the sio driver). o Put struct puc_device_description in struct puc_softc instead of having a pointer to a device description in the softc. This allows us to create device descriptions on the fly without having to use malloc() or otherwise have them staticly defined. o Move puc_find_description() from puc.c to puc_pci.c as it's specific to PCI. o Add EBUS and SBUS frontends for use on sparc64. Note that the P in puc stands for PCI, so we kinda mess things up here. It's too soon to worry about it though. We'll know what to do about it in time. NOTE: This commit changes the behaviour of puc(4) to not quieten the device probe and attach for child devices. The uart(4) driver provides additional device description that is valuable to have.

| | | | | | | | | | | | | | | | | | | Don't expect all RIDs to be PCI rids. The previous code made at least 1 mistake, even for PCI. Give the card definitions a chance to specify a init function. Use this instead of the gross superio hack. Move the win877 init function to puc_pci.c where it belongs. RIDs can actually be zero, don't set badmuxed if so. Set a less incorrect end for the construct SYS_RES_IOPORT entries, I guess both sio and lpt happen to use 8 IO ports, but that shouldn't really be hardcoded this way. Fixup puc_pccard.c to match. We're getting closer.
