* Last tweak before enabling intrs on slave cpus ... set their intr maskKanoj Sarcar2000-04-071-0/+2
| | | | right.
* Clear the TS bit from the master's status register (don't know whyKanoj Sarcar2000-04-074-6/+22
| | | | | | | | PROM is getting the bit set before entry into kernel). Fix per cpu frequency reporting. Fix bug so that we do not clear information about mips4 availability. Have the slaves flush their cache/tlb and set status based on what the master processor did.
* Initial attempt at seperating out per-cpu and per-hub code that needs toKanoj Sarcar2000-04-074-26/+94
| | | | be executed in a multicpu, multinode environment.
* Make the initial status register setting code for slaves similar to theKanoj Sarcar2000-04-061-16/+19

* Create idle threads for the slave processors and put them in theirKanoj Sarcar2000-04-062-12/+78

* Fix UP compiles.Kanoj Sarcar2000-04-051-0/+7

* Oops, I had overwritten head.S completely with another C file. Fixing.Kanoj Sarcar2000-04-051-127/+92

* Try to launch all the slave cpus in the system. Currently, I _think_Kanoj Sarcar2000-04-053-82/+146
| | | | | | only the slave on the same node as the master gets launched, investigating why the slaves on the other nodes are not ... Slave processors use a static stack surrently while booting up.
* o 32-bit ioctls (some at least)Ulf Carlsson2000-04-055-23/+793
| | | | | o some syscalls o check that the syscall is withing range
* Record nasid/cnode/cpuslice in the per cpu data structure during boot up.Kanoj Sarcar2000-04-042-13/+32

* Added a few klconfig functions from IRIX. This triggered some house cleaning,Kanoj Sarcar2000-04-044-68/+122
| | | | | ie, moving type declarations into sn/types.h and moving klconfig code from ip27-init.c into ip27-klconfig.c.
* Rudimentary code to launch slave processors by the master processor.Kanoj Sarcar2000-04-041-1/+123
| | | | Completely untested, never executed ...
* Rudimentary sendintr() routine to send intrs to other cpus. This needs toKanoj Sarcar2000-04-011-0/+37
| | | | | | pull in defines from intr.h/intr_public.h. Also, need to store percpu information regarding cpu slice # for cpu, hardware nasid and compact node id.
* save_and_cli and restore_flags ... not save_and_cli and __restore_flags ...Kanoj Sarcar2000-03-311-1/+1

* More placeholder stuff. Added pci_fixup_isp2x00() routine to set upLeo Dagum2000-03-301-2/+68
| | | | | | the device's config space registers and turn on byte swizzling in the bridge for this device (needs to be done before the driver sees it). Again, hardwired to slot 5. Will generalize later.
* Added pcibr_setup() routine to initialize some bridge registers differentLeo Dagum2000-03-301-1/+24
| | | | from what the prom gives us.
* Interrupts need to start at bit 7 in INT_PEND0 registers because bits [0..6]Leo Dagum2000-03-301-13/+44
| | | | | | are taken for various other sundry tasks. Also added QLOGICFC_SLOT5 kludge to bridge_startup(). I'll generalize this later, for now it means you have to have your isp2100 card in slot 5.
* When saving syscalls also save a6 and a7. We may need them later forRalf Baechle2000-03-281-0/+2

* ip27-irq.c, system.h: implement SMP intr on/off primitives similar to i386.Kanoj Sarcar2000-03-263-5/+200
| | | | | process.c, smp.c: minor initialization code. SMP compiles still hang at the scsi probing stage, no improvements.
* Minor memory accounting bug fixes to get cat /proc/meminfo and bootupKanoj Sarcar2000-03-251-2/+7
| | | | | Memory: report print sane values. Hack around a generic free_area_init_node() bug that can be removed once the generic code has been fixed.

* The fast tlb handlers [x]tlb_refill_debug blindly look at pgd/pmd/ptes.Kanoj Sarcar2000-03-163-2/+4
| | | | | | | So, _all_ page tables in the system _must_ be 2 pages, including empty_bad_page_table. And, the invalid page table _must_ be initialized to all invalid entries, so that even if the fast handler picks something up from an unallocated pmd/ptetable, the processor takes a mm fault.
