* Tlb miss handling updates: need to fill in the processor id only onceKanoj Sarcar2000-06-292-0/+3
| | | | during bootup.
* Add in the CONFIG_NUMA option for IP27s (distinct from DISCONTIGMEM whichKanoj Sarcar2000-06-273-0/+3
| | | | | might also be used by platforms with memory holes, but uniform access times). CONFIG_NUMA special code will probably make its way into generic kernel.
* We don't need CONFIG_SGI for IP27 builds, specially when the SMP kernelKanoj Sarcar2000-06-273-3/+2
| | | | | does not even compile ... restoring the IP27 specific config files to their previous versions.
* Explain pgd/pmd allocation failure strategies. Create a global bad-pmd-table,Kanoj Sarcar2000-06-273-47/+20
| | | | | | | distinct from invalid-pmd-table for use during pmd allocation failure (so as to differentiate pgd_bad and pgd_none). The bad page table must have invalid pte entries to catch any user references to the range of virtual addresses it covers.
* Fix another minor typo - get the global/special page symbols to pointKanoj Sarcar2000-06-271-1/+1
| | | | to their rightful locations.
* Cleanup CONFIG_SGI_IP35.Ralf Baechle2000-06-274-0/+5
|
* Delete pmd_present/pgd_present. Explain pgd/pmd/pte allocation andKanoj Sarcar2000-06-263-7/+7
| | | | | initialization. Make sure to allocate only one page for the page table (prevent memory leaks), since only one page is freed up.
* Merge with Linux 2.4.0-test2.Ralf Baechle2000-06-253-3/+0
|
* Fix typo to make sure the page directory/tables get aligned on to pageKanoj Sarcar2000-06-241-1/+1
| | | | boundaries.
* Sys32_fcntl from sparc to prevent procmail from confusing the kernel.Kanoj Sarcar2000-06-232-1/+62

* Fix struct stat64 in the 32-bit kernel and struct stat in the 64-bitRalf Baechle2000-06-202-30/+7
| | | | | kernel to match each other and the the glibc definition. The glibc part of this change has been sent to Andreas.
* Merge with 2.4.0-test1-ac21 + pile of MIPS cleanups to make mergingRalf Baechle2000-06-1910-50/+43
| | | | | possible. Chainsawed RM200 kernel to compile again. Jazz machine status unknown.

* One more 32bit call.Kanoj Sarcar2000-06-142-1/+45
|
* The tlb mod/load/store exception handlers _have_ to go to do_page_fault,Kanoj Sarcar2000-06-133-159/+15
| | | | | and can not do with pte bit twiddling without grabbing page_table_lock. Reinstate most of the old code, after disposing of an extra jump.
* Fix a possible race in the initialization code.Kanoj Sarcar2000-06-131-8/+5
|
* Support to put the lowlevel exception handlers in node local memory.Kanoj Sarcar2000-06-134-0/+28
|
* When doing kernel text replication, make sure we do not scribble onKanoj Sarcar2000-06-132-21/+27
| | | | | top of the replicated kernel text thinking it is unused memory. This lets us get to multiuser on a replicated kernel text system.
* Add in a build/config option for kernel text replication.Kanoj Sarcar2000-06-124-0/+6
|
* Fix the code that puts in (possibly different) tlblo0/tlblo1 entriesKanoj Sarcar2000-06-121-3/+5
| | | | for the mapped kernel. Compute the "pfn" field properly.
* Have the slave bootstrap code actually look at the text and data serverKanoj Sarcar2000-06-092-13/+14
| | | | | nasids that the master nasid found for it. Sanitize the replication procedures.
* Add in the hooks to do kernel text replication. Now start debugging thisKanoj Sarcar2000-06-093-1/+124
| | | | code.
* Each node needs to have a structure that the master nasid fills up toKanoj Sarcar2000-06-091-1/+0
| | | | | tell it where to get the kernel data from (ie, which nasid holds the kernel data). Remove debug cruft from head.S.
* Need to have the nasid of the boot/master node for future uses.Kanoj Sarcar2000-06-091-0/+2
|
* Step one of trying to remove the assumption that nasid 0 is presentKanoj Sarcar2000-06-081-3/+33
| | | | from the mapped kernel code.
* SMP Mapped kernel fixes to go along with the new layout. Use properlyKanoj Sarcar2000-06-081-1/+1
| | | | | massaged bootstrap address so that the PRM launches the slaves into legal code.
* Mapped kernel changes: create elf sections as close as possible toKanoj Sarcar2000-06-084-33/+30
| | | | | IRIX, to get the same kind of loader behavior. Read comments in mapped_kernel.h for more details.
* Reboot was doing halt and halt was crashing the machine, fixed.Ralf Baechle2000-06-071-6/+13

* *** empty log message ***Ralf Baechle2000-06-061-12/+13
|
* Get the mapped kernel working for SMP kernels. While launching slaves,Kanoj Sarcar2000-06-061-3/+4
| | | | | pass the proper address for the slave bootstrap routine based on where the kernel is compiled at.
* Get some type definitions into their rightful places for wider usage.Kanoj Sarcar2000-06-061-4/+5
|
* MAke sure the mapped kernel does not loose its prom command line.Kanoj Sarcar2000-06-061-1/+0
|
* Entrylo1 must at least be marked global for the tlb entry mapping theKanoj Sarcar2000-06-061-1/+2
| | | | mapped kernel text/data for tlb translation to work properly.
* The tlbwired register is now set up in the head.S code.Kanoj Sarcar2000-06-063-365/+115
|
* Initial rudimentary support for mapped kernel. The kernel text and dataKanoj Sarcar2000-06-066-89/+381
| | | | | | are placed in the cksseg area, and such behavior is tuned thru a make option (off by default). Basis for future kernel text replication and partitioning work/study.
* Launch the CPUs one by one until we can make sure that weUlf Carlsson2000-06-061-7/+11
| | | | | add PCI devices from different PCI buses to the list of PCI devices in the same order every time we boot the system.
* Delete unused reference to linker generated symbol.Kanoj Sarcar2000-06-051-2/+0
|
* Further cleanups to the ld script files not to do more than needed.Kanoj Sarcar2000-06-054-12/+4
| | | | Replace uses of _ftext with the more generic _stext.
* Clean up generation of unused symbols.Kanoj Sarcar2000-06-052-6/+0
|
* Fix the address twiddling. For some reason, the code that I was expectingKanoj Sarcar2000-06-051-11/+10
| | | | | was not getting generated (coding problem or cpp/as problem, no point tracking this down).
* The master processor now waits for all enabled cpus to come into theKanoj Sarcar2000-06-021-1/+1
| | | | kernel before progressing (as opposed to waiting for _all_ slave cpus).
* Most of the kernel arrays/data structures and low level proceduresKanoj Sarcar2000-06-023-27/+28
| | | | | now accept the kernel assigned cpuid (instead of the prom assigned id) as input/index. The only exception is the early boot up code.
* Set smp_num_cpus in the IP27 specific code. Getting ready to handleKanoj Sarcar2000-06-022-3/+1
| | | | PROM-disabled cpus.
* Fix some type definitions, add a new field in the per-processor dataKanoj Sarcar2000-06-021-1/+1
| | | | | area to store the PROM assigned cpuid that is used by most of the IP27 kernel and prom data strucutures.
* Add the node offset to the IOC3 to the PCI resourceUlf Carlsson2000-06-011-0/+4
| | | | | address for all IOC3 devices. We will now be able to reach IOC3 cards on other nodes than the first one.
* Now that __kernel_clock_t is 64 bits, we need to make sure we have aKanoj Sarcar2000-06-012-1/+30
| | | | | | 32 bit version of the sys_times() call (like sparc64, ia64), else the kernel overwrites user space it is not supposed to. Compilations could not be done because of this.
* Only enter do_timer from the first CPU.Ulf Carlsson2000-05-311-16/+16
| | | | | Per processor interrupts at 100 Hz on each processor. Adjust do_gettimeofday to get info from first CPU.
* Remove all IOC3 hacks. IOC3 now allocates it's resources the same wayRalf Baechle2000-05-302-71/+79
| | | | | that all others do. Further cleanup to make ioc3-eth.c start looking like a driver.
* Don't make Origin SMP as experimental.Ralf Baechle2000-05-301-1/+1
