same interrupt, and something isn't quite right with the mace interrupt
dispatcher. Disable for now.
Pointed out by Tillman Hodgson and confirmed by ozone on port-sgimips.
driver. Still some issues:
* framebuffer setup seems incomplete. Some drawing primitives work 100%
of the time, while others fail one in ten tries. Perhaps my board is
slightly broken, as the exact model as probed by ARCS seems to shift
between Elan and XS24 from time to time.
* characters are drawn bottom-up rather than top-down (as the wsfont
definitions expect).
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.
In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.
to only call pckbc_machdep_cnattach() if this is present. This allows
pckbc_machdep_cnattach() to be omitted entirely on most ports, where it only
returns ENXIO anyway.
The devices with this attribute at the moment are pc(4) on i386 and bebox, and
pckbc on sparc, where pckbc_machdep_cnattach() mysteriously returns 0 rather
than ENXIO.
* detect and store vc2 revision. This is (likely) the important factor in
determining the proper cursor offset, so add a bit of logic that does the
right thing on my revision 0 vc2. This will have to be determined
empirically, revision by revision.
* take a stab at detecting framebuffer depth. SGI does it quite differently,
but their algorithm doesn't work, so we'll do it along the same lines as
linux.
* implement newport_mmap() for use by X. The necessary xsrc commits have been
made (with the notable exception of the config/cf changes, which probably
shouldn't go in until 4.4.0 has been imported).
* Add resolution and depth variables to softc (for use in X driver, although
depth detection is currently problematic),
* Store more information about various chip revisions,
* Implement ioctls to help the X driver detect device presence and geometry.
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue
interrupts and timer calibration yet is also attached at mainbus).
Introduce the INDY_R4600_CACHE config option, which more accurately describes
the code enabled by this option.
This renders #ifdef IPxx completely obsolete, thus we theoretically can unify
the GENERIC files if a workable load address relocation scheme can be found.
mace devices to their own mace/ directory. Alter conf/files.sgimips to
reflect this change in a sane manner (i.e., pull in dev/files.dev and
mace/files.mace when appropriate).
At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().
* move all device-specific bitbanging to the device drivers in question --
i.e., the ip32 init code doesn't access the CRIME registers directly but
instead trusts the CRIME driver to DTRT. machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c. After the interrupt handler cleanup, the
actual platform-dependent code was so minimal (rev identification, mask level
initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.
Tested on my ip22 and ip32. Discussed with pooka@, rafal@.
