* Add locking to ppc and ppbus and mark the whole lot MPSAFE:jhb2009-01-217-80/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - To avoid having a bunch of locks that end up always getting acquired as a group, give each ppc(4) device a mutex which it shares with all the child devices including ppbus(4), lpt(4), plip(4), etc. This mutex is then used for all the locking. - Rework the interrupt handling stuff yet again. Now ppbus drivers setup their interrupt handler during attach and tear it down during detach like most other drivers. ppbus(4) only invokes the interrupt handler of the device that currently owns the bus (if any) when an interrupt occurs, however. Also, interrupt handlers in general now accept their softc pointers as their argument rather than the device_t. Another feature of the ppbus interrupt handlers is that they are called with the parent ppc device's lock already held. This minimizes the number of lock operations during an interrupt. - Mark plip(4), lpt(4), pcfclock(4), ppi(4), vpo(4) MPSAFE. - lpbb(4) uses the ppc lock instead of Giant. - Other plip(4) changes: - Add a mutex to protect the global tables in plip(4) and free them on module unload. - Add a detach routine. - Split out the init/stop code from the ioctl routine into separate functions. - Other lpt(4) changes: - Use device_printf(). - Use a dedicated callout for the lptout timer. - Allocate the I/O buffers at attach and detach rather than during open and close as this simplifies the locking at the cost of 1024+32 bytes when the driver is attached. - Other ppi(4) changes: - Use an sx lock to serialize open and close. - Remove unused HADBUS flag. - Add a detach routine. - Use a malloc'd buffer for each read and write to avoid races with concurrent read/write. - Other pps(4) changes: - Use a callout rather than a callout handle with timeout(). - Conform to the new ppbus requirements (regular mutex, non-filter interrupt handler). pps(4) is probably going to have to become a standalone driver that doesn't use ppbus(4) to satisfy it's requirements for low latency as a result. - Use an sx lock to serialize open and close. - Other vpo(4) changes: - Use the parent ppc device's lock to create the CAM sim instead of Giant. - Other ppc(4) changes: - Fix ppc_isa's detach method to detach instead of calling attach. Tested by: no one :-(

| | | | | | | | | | | | | | | | | | | | | | | | | | | other fixes: - Add pointers back to device_t objects in softc structures instead of storing the unit and using devclass_get_device(). - Add 'lpbb', 'pcf', 'pps', and 'vpo' child devices to every 'ppbus' device instead of just the first one. - Store softc pointers in si_drv1 of character devices instead of pulling the unit number from the minor number and using devclass_get_softc() and devclass_get_device(). - Store the LP_BYPASS flag in si_drv2 instead of encoding it in the minor number. - Destroy character devices for lpt(4) when detaching the device. - Use bus_print_child_footer() instead of duplicating it in ppbus_print_child() and fix ppbus_print_child()'s return value. - Remove unused AVM ivar from ppbus. - Don't store the 'mode' ivar in the ppbus ivars since we always fetch it from the parent anyway. - Try to detach all the child devices before deleting them in ppbus_detach(). - Use pause() instead of a tsleep() on a dummy address when polling the ppbus. - Use if_printf() and device_printf() instead of explicit names with unit numbers.

* Rework the handling of interrupt handlers for children of ppc and ppbus:jhb2008-09-157-63/+116
| | | | | | | | | | | | | | | | | - Retire IVARs for passing IRQs around. Instead, ppbus and ppc now allow child devices to access the interrupt by via a rid 0 IRQ resource using bus_alloc_resource_any(). - ppc creates its own interrupt event to manage the interrupt handlers of child devices. ppc does not allow child devices to use filters. It could allow this if needed, but none of the current drivers use them and it adds a good bit of complication. It uses intr_event_execute_handlers() to fire the child device interrupt handlers from its threaded interrupt handler. - Remove the ppbus_dummy_intr() hack. Now the ppc device always has an interrupt handler registered and we no longer bounce all the way up to nexus to manage adding/removing ppbus child interrupt handlers. Instead, the child handlers are added and removed to the private interrupt event in the ppc device.

* Rewrite of puc(4). Significant changes are:marcel2006-04-281-0/+13
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | end for isa(4). o Add a seperate bus frontend for acpi(4) and allow ISA DMA for it when ISA is configured in the kernel. This allows acpi(4) attachments in non-ISA configurations, as is possible for ia64. o Add a seperate bus frontend for pci(4) and detect known single port parallel cards. o Merge PC98 specific changes under pc98/cbus into the MI driver. The changes are minor enough for conditional compilation and in this form invites better abstraction. o Have ppc(4) usabled on all platforms, now that ISA specifics are untangled enough.

| | | | | | | | things like sound cards can get called "Parallel port". A note to the unwary; the isa-pnp devices in the system are probed like PCI - each device ID is passed to *all* isa probe routines to find the best match. If the driver is not prepared to deal with this, it must abort in this scenario or it will try and claim all PnP devices.
* Port of ppbus standalone framework to the newbus system.nsouch2000-01-142-318/+529
| | | | | | | | | | | | | | | | | | | | | Note1: the correct interrupt level is invoked correctly for each driver. For this purpose, drivers request the bus before being able to call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus core when drivers release it. Thus, when BUS_SETUP_INTR is called at ppbus driver level, ppbus checks that the caller owns the bus and stores the interrupt handler cookie (in order to unregister it later). Printing is impossible while plip link is up is still TRUE. vpo (ZIP driver) and lpt are make in such a way that using the ZIP and printing concurrently is permitted is also TRUE. Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET is now needed to force chipset detection. If set, the flags 0x40 still avoid detection at boot. Port of the pcf(4) driver to the newbus system (was previously directly connected to the rootbus and attached by a bogus pcf_isa_probe function).
