MFC: Add support for _CID package types and use dynamic storage for

Update this driver to be more module friendly:

- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of using a statically sized array that depended on 'options SMP'. - Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a match. - Always call smp_rendezvous() since UP kernels now provide this. - Use mp_ncpus rather than cpu_ndevices when determining if we need to disable C3 for SMP machines.

idx'th present CPU with pc_acpi_id equal to *acpi_id. If *acpi_id does not match that processor's pc_acpi_id, return the value for ProcId derived from the MADT in *acpi_id. If pc_acpi_id is 0xffffffff, always override it with the value of *acpi_id. Finally, return pc_cpuid in *cpu_id and use that as our primary key. * Use pc_cpuid as our unique key because we know it is valid since MD code set it. The values for ProcId in the ASL and MADT don't match up on some machines (!), forcing us to fall back to ordered probing in that case. * Remove some #ifdef SMP since the refcount doesn't hurt performance and will be needed for dynamic _CST objects. Only one #ifdef SMP (for smp_rendezvous) remains. * Hook up SMP in the compile flags in the Makefile. Tested by: marcel, truckman Approved by: re (scottl)

* Add a DEVMETHOD for acpi so that child detach methods get called. Add

2003-11-19T20:27:06Z

an acpi_cpu method for shutdown that disables entry to acpi_cpu_idle and then IPIs/waits for threads to exit. This fixes a panic late in reboot in the SMP case. * In the !SMP case, don't use the processor id filled out by the MADT since there can only be one processor. This was causing a panic in acpi_cpu_idle if the id was 1 since the data was being dereferenced from cpu_softc[1] even though the actual data was in cpu_softc[0] (which is correct). * Rework the initialization functions so that cpu_idle_hook is written late in the boot process. * Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables. This will help SMP boxes that have _CST or multiple P_BLKs. No such boxes are known at this time. * Always allocate the C1 state, even if the P_BLK is invalid. This means we will always take over idling if enabled. Remove the value -1 as valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt. * Reduce locking for the throttle initialization case to around the write to the smi_cmd port. Add disabled code to write the CST_CNT. It will be enabled once _CST re-evaluation is tested (post 5.2R).

Implement Cx CPU idle states and updated throttling support.

2003-11-15T19:26:06Z

* Use the cpu_idle_hook() to do idling for C1-C3. * Use both _CST and the FADT to detect Cx states. * Use both _PTC and P_CNT for controlling throttling. * Add a notify handler to detect changes in _CST and _PSS * Call the _INI function for each processor if present. This will be done by ACPI-CA in the future. * Fix a bug on SMP systems where CPUs will attach multiple times if the bus is rescan. * Document new sysctls for controlling idling.
