Don't disable the TSC with statclock_disable.

- Implement selwakeuppri() which allows raising the priority of a

thread being waken up. The thread waken up can run at a priority as high as after tsleep(). - Replace selwakeup()s with selwakeuppri()s and pass appropriate priorities. - Add cv_broadcastpri() which raises the priority of the broadcast threads. Used by selwakeuppri() if collision occurs. Not objected in: -arch, -current

New APIC support code:

- The apic interrupt entry points have been rewritten so that each entry point can serve 32 different vectors. When the entry is executed, it uses one of the 32-bit ISR registers to determine which vector in its assigned range was triggered. Thus, the apic code can support 159 different interrupt vectors with only 5 entry points. - We now always to disable the local APIC to work around an errata in certain PPros and then re-enable it again if we decide to use the APICs to route interrupts. - We no longer map IO APICs or local APICs using special page table entries. Instead, we just use pmap_mapdev(). We also no longer export the virtual address of the local APIC as a global symbol to the rest of the system, but only in local_apic.c. To aid this, the APIC ID of each CPU is exported as a per-CPU variable. - Interrupt sources are provided for each intpin on each IO APIC. Currently, each source is given a unique interrupt vector meaning that PCI interrupts are not shared on most machines with an I/O APIC. That mapping for interrupt sources to interrupt vectors is up to the APIC enumerator driver however. - We no longer probe to see if we need to use mixed mode to route IRQ 0, instead we always use mixed mode to route IRQ 0 for now. This can be disabled via the 'NO_MIXED_MODE' kernel option. - The npx(4) driver now always probes to see if a built-in FPU is present since this test can now be performed with the new APIC code. However, an SMP kernel will panic if there is more than one CPU and a built-in FPU is not found. - PCI interrupts are now properly routed when using APICs to route interrupts, so remove the hack to psuedo-route interrupts when the intpin register was read. - The apic.h header was moved to apicreg.h and a new apicvar.h header that declares the APIs used by the new APIC code was added.

Fix a panic that occurs when resuming. For some reason, sc->cur_scp is

Look at the equipment list for amd64 as well as i386 for autodetecting

Change fb_attach() and fb_detach() to take a integer unit number rather

than a dev_t. All of the dev_t's passed were bogusly created with makedev()

Per TRB vote: restore the aquire_timer0 and associated goo. This will

2003-09-24T15:33:33Z

be gone in FreeBSD 6, so put BURN_BRIDGES around it. The TRB also felt that if something better comes along sooner, it can be used to replace this code. Delayed by: BSDcon and subsequent disk crash.

Pick up softc from dev_t rathern than through newbus gymnastics.
