* Add locking to ppc and ppbus and mark the whole lot MPSAFE:jhb2009-01-2121-497/+830
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Add Unicode rendering to the teken demo application.ed2009-01-212-11/+32
| | | | | | | | | Some time ago I tried adding Unicode rendering to the teken demo application, but I didn't get it working. It seems I forgot to call setlocale(). Polish this code and make sure it doesn't get lost. Also a small fix for my previous commit: all Unicode characters in teken_boxdrawing are below 0x10000, so store them as 16-bit values.

| | | | | | | | | | | | VOP_MARKATIME() since unlike the rest of VOP_SETATTR(), VA_MARKATIME can be performed while holding a shared vnode lock (the same functionality is done internally by VOP_READ which can run with a shared vnode lock).
