2009-12-30	curcpu()->ci_curpmap added. ok miod@	Takuya ASADA

2009-12-28	Fix compile error caused from previous commit	Takuya ASADA

2009-12-28	MP-safe pmap implemented, enable IPI in interrupt handler to avoid deadlock.	Takuya ASADA
	ok miod@
2009-12-25	Pass both the virtual address and the physical address of the memory range	Miod Vallat
	when invoking the cache functions. The physical address is needed when operating on physically-indexed caches, such as the L2 cache on Loongson processors. Preprocessor abuse makes sure that the physical address computation gets compiled out when running on a kernel compiled for virtually-indexed caches only, such as the sgi kernel.
2009-12-25	Don't bother returning a value in *_InvalidateICache(), as it's supposed to be	Miod Vallat
	a void function.
2009-12-13	bit less aggressive about hiding; ok miod	Theo de Raadt

2009-12-12	Protect more definitions userland doesn't need to care about with _KERNEL	Miod Vallat

2009-12-12	Switch page size from 4KB to 16KB on R10k kernels without R5k support	Miod Vallat
	(i.e. IP27 and IP30 sgi kernels).
2009-12-12	Introduce various CPU_### options to enable cpu-specific code or workarounds;	Miod Vallat
	be sure to rerun config(8) on your kernel configuration files.
2009-12-12	unifdef -D__LP64__	Miod Vallat

2009-12-11	More changes to avoid truncating 64 bit pointers to 32 bits and sign-extending	Miod Vallat
	them; allows userland with stack beyond 2GB to run.
2009-12-08	Unconditionnaly move kernel virtual memory space to XKSEG, now that previous	Miod Vallat
	context.S fixes allows these settings to work for kernels linked in CKSEG0.
2009-12-08	In cpu_switchto(), correctly ignore CKSEG0 curprocpaddr (and do not update the	Miod Vallat
	wired TLB entries).
2009-12-08	Use a whole page for msgbuf if page size is larger than 4KB, instead of	Miod Vallat
	the current 8KB.
2009-12-07	Correctly skip available memory regions without (kernel) page aligned	Miod Vallat
	boundaries, entirely contained within a kernel page; issue raised by drahn@
2009-12-07	Sync VM_MIN_ADDRESS with __LDPGSZ again.	Miod Vallat

2009-12-07	Support for 16KB page size kernels; page size is now set in <machine/param.h>	Miod Vallat
	rather than <mips64/param.h>. For now, kernels are kept at 4KB to give people some time to build 16KB compatible binaries; this will change before the end of this release cycle. Use of 16KB page size kernels yields a 18% speedup (which, offset by the 1.6% slowdown caused by the pmap changes, yields a 16.6% overall speedup).
2009-12-07	If UPAGES would turn out to be 1, instead of using wired TLB entries to map	Miod Vallat
	the u area after each context switch, simply convert it to an XKPHYS address, so that access to it never faults. Idea from NetBSD.
2009-12-07	Use a pool to manage pmap pte pages and top level segment table, instead of	Miod Vallat
	directly allocating pages from uvm; this will allow us to eventually use a different kernel page size without having to alter the pmap structures layout. No functional change; measured slowdown of 1.6% for 4KB page kernels.
2009-12-07	When converting ARCBios memory spaces from ARCBios page size to the kernel	Miod Vallat
	page size, be sure to pick the strictest interval so as not to incorrectly claim ARCBios reserved data not (kernel) page size aligned as free memory. No functional change since the kernel uses the same page size as ARCBios (at the moment).
2009-12-07	Be sure to always check tlbp return values for strictly negative values	Miod Vallat
	to consider the probe as failed; tlb pair #0 does not deserve to be magic in any way.
2009-12-07	When trying to return to ARCBios on a 32 bit ARCBios machine (such as the O2),	Miod Vallat
	disable interrupts and unconditionnaly use proc0 u area as the stack, so that once ARCBios loses the upper 32 bits of the stack pointer, accessing the stack does not fault (proc0 u area is allocated in CKSEG0 for this reason).
2009-12-02	use kstack for curprocpaddr instead of proc0paddr.	Takuya ASADA
	ok miod@
2009-11-30	Crank __LDPGSZ from 4KB to 16KB, in preparation for a kernel page size	Miod Vallat
	increase as well. Binaries compiled before this change will not work once the kernel page size is cranked (in a few weeks), so you might want to update your userland and packages soon.
2009-11-28	missing #ifdef MULTIPROCESSOR protection around locking code.	Miod Vallat

2009-11-27	Move MB_LEN_MAX into the machine-independent sys/limits.h header,	Philip Guenthe
	rather than defining it separately for each architecture. Also set it to 4, to accommodate for future UTF-8 support (rfc3629). Diff by stsp, committing to catch the libc major bump ok kettenis@, guenther@
2009-11-27	atomic counter increment for SMP.	Takuya ASADA
	ok jsing@
2009-11-26	Now IPI can interrupt to clock interrupt handler.	Takuya ASADA
	It prevents deadlock with TLB shootdown and clock interrupt. ok miod@
2009-11-26	initialize cpu_info correctly.	Takuya ASADA
	ok miod@
2009-11-25	IP30 IPI implementation.	Takuya ASADA
	Also few xheart modification for SMP. ok miod@
2009-11-24	smp_malloc() implemented.	Takuya ASADA
	This function allocates memory using malloc or uvm_pglistalloc, then returns XKPHYS address of allocated memory. It's for avoid using virtual address on secondary cpus in early stage, and also in TLB handler. ok miod@
2009-11-22	removing unnecessary locks.	Takuya ASADA
	ok jsing@
2009-11-22	ncpus, ncpufound values are corrected.	Takuya ASADA
	ok miod@
2009-11-22	SMP support on MIPS clock.	Takuya ASADA
	ok miod@
2009-11-22	Fix compile error in uniprocessor kernel.	Takuya ASADA
	ok jsing@
2009-11-22	Correct cording style.	Takuya ASADA
	ok jsing@
2009-11-22	Allow mips ports to override VM_{MIN,MAX}_KERNEL_ADDRESS, and provide the	Miod Vallat
	address as a kernel variable for use by libkvm. On sgi IP27 and IP30 kernels, use XKSEG instead of CKSSEG; this will allow kernel KVM size to grow in the future if necessary.
2009-11-21	Fix uninitialized variables in db_stack_trace_print(), and honour the	Miod Vallat
	frame count argument.
2009-11-21	mplock, rw_cas implemented	Takuya ASADA
	ok miod@
2009-11-19	Rename KSEG* defines to CKSEG* to match their names in 64 bit mode; also	Miod Vallat
	define more 64 bit spaces.
2009-11-19	All callers of updateimask() immediately enable interrupts afterwards, so do	Miod Vallat
	it in updateimask() itself. No functional change.
2009-11-19	Remove code allowing native binaries with O32 ABI to run, there aren't any...	Miod Vallat

2009-11-19	Factor triplicated code responsible to add memory information into a	Miod Vallat
	single place.
2009-11-18	Stricter type usage (width and signedness); first step towards 64 bit ptes.	Miod Vallat

2009-11-12	typo	Miod Vallat

2009-11-07	Replace option TGT_ORIGIN200 and TGT_ORIGIN2000 with a single option,	Miod Vallat
	TGT_ORIGIN, which enables support for all IP27 and IP35 systems. The original two options have always been used together, and go back to when pefo thought supporting multiple nodes would be significant work. Since an Origin 200 can be a dual-node system, making a distinction between single node and multiple node systems is a moot point anyway. Be sure to rerun config(8) before rebuilding a kernel.
2009-11-07	Change sgi system identification from a single system type list, to a smaller	Miod Vallat
	system type list (which really is the system family) and a subsystem type. No functional change yet.
2009-11-04	Get rid of __HAVE_GENERIC_SOFT_INTERRUPTS now that all our platforms support it.	Mark Kettenis
	ok jsing@, miod@
2009-10-30	Support IP30 secondary cpu bootup. ok miod@	Takuya ASADA

2009-10-26	Rename struct confargs to struct mainbus_attach_args for consistency and also	Miod Vallat
	to prevent further abuse of it.
