independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'. Devices that can be present on a TC or as ioctl asic/mainbus builtins use the same `struct confargs'. * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from an old, now-obsolete sys/arch/alpha snapshot. * Update the comments and debugging code in interrupt handlers to be consistent with the machine-independent TC support. Other commits that overlap the same source files include: re-enabling clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i. |
