* Fixed bridge_init() so it sets registers for theLeo Dagum2000-04-101-2/+5
| | | | | | | | calling process's bridge (not necessarily node 0), and removed call to set_cp0_status() (now in per_cpu_init()). b_wid_int_upper still points to node 0, I don't want to change this till I have a multinode system and kernel to test on.

* Let CONFIG_SERIAL_CONSOLE be selectable - At least there is some referenceFlorian Lohoff2000-04-081-0/+3
| | | | | | to it in arch/mips/sgi/kernel/setup.c - Probably sgiserial.c should be fixed to only include console stuff is CONFIG_SERIAL_CONSOLE although this only gets interesting if the PROM_CONSOLE/Framebuffers gets supported.
* Revert changes here - We have fixed Config.in - CONFIG_SERIAL is not selectableFlorian Lohoff2000-04-081-4/+0

* For slave nodes, make sure not to touch the lower part of their localKanoj Sarcar2000-04-081-6/+1
| | | | | memory, which is used by the prom. Gets really hard to do things like launch processors on slave nodes otherwise.
* Fix this UP/MP microoptimization business with cpu_data[] andKanoj Sarcar2000-04-083-9/+7
| | | | | boot_cpu_data once and for all. Generic mips64/IP27 code wants to do cpu_data[cpuid] everywhere ...

* Make it so that clock interrupts can be received on all cpus on the node.Kanoj Sarcar2000-04-081-2/+3

* Minor cleanup - do not invent new synonyms. Use ST0_IE instead of new nameKanoj Sarcar2000-04-071-4/+2

* Port paccess.h from mips64. mips32 paccess.h differs from the original one inGleb O. Raiko2000-04-072-1/+141
| | | | | | | | the following: o works in case a constant address is passed to get_dbe/put_dbe o uses faster binary search :-) o the kernel are linked successfully even if get_dbe/put_dbe aren't used
* Last tweak before enabling intrs on slave cpus ... set their intr maskKanoj Sarcar2000-04-071-0/+2

* Clear the TS bit from the master's status register (don't know whyKanoj Sarcar2000-04-075-6/+23
| | | | | | | | 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 Sarcar2000-04-076-26/+99

| | | | | | needed to be set, and queuecommand had to default specify at least a Simple Queue otherwise the TEST_UNIT_READY commands failed and scsi_scan couldn't find the drives.

| | | | | | 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.

* Added a few klconfig functions from IRIX. This triggered some house cleaning,Kanoj Sarcar2000-04-047-69/+138
| | | | | ie, moving type declarations into sn/types.h and moving klconfig code from ip27-init.c into ip27-klconfig.c.

* Rudimentary sendintr() routine to send intrs to other cpus. This needs toKanoj Sarcar2000-04-015-3/+236

* spin_trylock acts on a word memory pointer, and can not use test_and_set_bitKanoj Sarcar2000-03-311-1/+18

* Put an instruction in the branch delay slot of the read_unlock()Kanoj Sarcar2000-03-311-0/+1

* Some minor changes to turn on 64-bittiness.Leo Dagum2000-03-312-17/+27

* 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.
* Added QLOGICFC_SLOT5 definition to Origin 'hacks' section at bottom.Leo Dagum2000-03-301-0/+1
|
* 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.
