* Add locking to ppc and ppbus and mark the whole lot MPSAFE:John Baldwin2009-01-211-64/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Rework the handling of interrupt handlers for children of ppc and ppbus:John Baldwin2008-09-151-57/+101
| | | | | | | | | | | | | | | | | | | | - 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. Notes: svn path=/head/; revision=183053

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.

* Port of ppbus standalone framework to the newbus system.Nicolas Souchu2000-01-141-308/+506
| | | | | | | | | | | | | | | | | | | | | | | | 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.
