sys: Use membar_release/acquire around reference drop. This just goes through my recent reference count membar audit and changes membar_exit to membar_release and membar_enter to membar_acquire -- this should make everything cheaper on most CPUs without hurting correctness, because membar_acquire is generally cheaper than membar_enter.

Update to support EFI runtime outside the kernel virtual address space by creating an EFI RT pmap that can be activated / deactivated when required. Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines. On Arm64 the usage of pmapboot_enter is reduced and the mappings are created much later in the boot process -- now in cpu_startup_hook. Backward compatiblity for KVA mapped RT from old bootaa64.efi is maintained. Adding support to other platforms should be easier as a result.

sys: Membar audit around reference count releases. If two threads are using an object that is freed when the reference count goes to zero, we need to ensure that all memory operations related to the object happen before freeing the object. Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one thread takes responsibility for freeing, but it's not enough to ensure that the other thread's memory operations happen before the freeing. Consider: Thread A Thread B obj->foo = 42; obj->baz = 73; mumble(&obj->bar); grumble(&obj->quux); /* membar_exit(); */ /* membar_exit(); */ atomic_dec -- not last atomic_dec -- last /* membar_enter(); */ KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); The memory barriers ensure that obj->foo = 42; mumble(&obj->bar); in thread A happens before KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); in thread B. Without them, this ordering is not guaranteed. So in general it is necessary to do membar_exit(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_enter(); to release a reference, for the `last one out hit the lights' style of reference counting. (This is in contrast to the style where one thread blocks new references and then waits under a lock for existing ones to drain with a condvar -- no membar needed thanks to mutex(9).) I searched for atomic_dec to find all these. Obviously we ought to have a better abstraction for this because there's so much copypasta. This is a stop-gap measure to fix actual bugs until we have that. It would be nice if an abstraction could gracefully handle the different styles of reference counting in use -- some years ago I drafted an API for this, but making it cover everything got a little out of hand (particularly with struct vnode::v_usecount) and I ended up setting it aside to work on psref/localcount instead for better scalability. I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I only put it on things that look performance-critical on 5sec review. We should really adopt membar_enter_preatomic/membar_exit_postatomic or something (except they are applicable only to atomic r/m/w, not to atomic_load/store_*, making the naming annoying) and get rid of all the ifdefs.

slightly change and fix the semantics of pool_set*wat(), pool_sethardlimit() and pool_prime() (and their pool_cache_* counterparts): - the pool_set*wat() APIs are supposed to specify thresholds for the count of free items in the pool before pool pages are automatically allocated or freed during pool_get() / pool_put(), whereas pool_sethardlimit() and pool_prime() are supposed to specify minimum and maximum numbers of total items in the pool (both free and allocated). these were somewhat conflated in the existing code, so separate them as they were intended. - change pool_prime() to take an absolute number of items to preallocate rather than an increment over whatever was done before, and wait for any memory allocations to succeed. since pool_prime() can no longer fail after this, change its return value to void and adjust all callers. - pool_setlowat() is documented as not immediately attempting to allocate any memory, but it was changed some time ago to immediately try to allocate up to the lowat level, so just fix the manpage to describe the current behaviour. - add a pool_cache_prime() to complete the API set.

Fix the armv[67] memory attributes for uncached memory. Previously it was mapped as strongly-ordered which meant that unaligned accesses would fault. armv7_generic_bs_map now maps pages with PMAP_DEV which is treated as SO bus_dma continues to use PMAP_NOCACHE as appropriate, but this now get mapped to the correct memory attribute bits for armv[67] DEVMAP_ENTRY usees a new flag PTE_DEV. The workaround for the unaligned access faults is now removed. XXX Other armv[67] boards bus_space implementations should be checked. XXX There is scope to reduce the difference to aarch64

A fix and an optimisation to pmap_l1tt_free - in the !__HAVE_MM_MD_DIRECT_MAPPED_PHYS case pass UVM_KMF_WIRED so that the mappings are removed and the KVA is released. Fixes the KASSERT seen in the automated test runs. - in the __HAVE_MM_MD_DIRECT_MAPPED_PHYS case we can work out pa much easier than caling pmap_extract.

Use 4K pages on ARM_MMU_EXTENDED platforms (all armv[67] except RPI) by creating a new pool l1ttpl for the userland L1 translation table which needs to be 8KB and 8KB aligned. Limit the pool to maxproc and add hooks to allow the sysctl changing of maxproc to adjust the pool. This comes at a 5% performance penalty for build.sh -j8 kernel on a Tegra TK1.

Pull up following revision(s) (requested by bouyer in ticket #1246):
sys/arch/arm/arm32/pmap.c: revision 1.373 (via patch)
Fix a deadlock between the pool and pmap codes:
- cpu0 grabs the kernel lock (e.g. from a non-MPSAFE interrupt) and
calls pool_get().
- cpu1 does a pool_get() on the same pool from MPSAFE code, which needs a
pool_page_alloc(), which ends up in pmap_extract_coherency().
So cpu0 holds the kernel_lock and wants the pool lock. cpu1 holds the pool
lock and wants the kernel_lock in pmap_extract_coherency().
The pmap code should not rely on kernel_lock. Intead make the
pmap_kernel()->pm_obj_lock a IPL_VM lock and use it as pmap lock
(thus dropping the pmap test pmap_{acquire,release}_pmap_lock()).
This needs to be a IPL_VM because unlike user pmaps, this can be locked
from interrupt context.
Add a IPL_NONE lock for pmap_growkernel(). We can't use
pmap_kernel()->pm_obj_lock here because pmap_grow_map() may sleep.
Make pmap_lock (which may be locked with pm_obj_lock held) a IPL_VM
lock in all case.
reorder a few things to not call pool_get()/pool_put() (which may sleep)
with pm_obj_lock held.
Patch initially posted to port-arm@ on April 19, improved patch (per
suggestions from Nick Hudson and Jason Thorpe) on April 21.

Provide generic start code that assumes the MMU is off and caches are disabled as per the linux booting protocol for ARMv6 and ARMv7 boards. u-boot image type should be changed to 'linux' for correct behaviour. The new start code builds a minimal "bootstrap" L1PT with cached access disabled and uses the same table for all processors. AP startup is performed in less steps and more code is written in C. The bootstrap tables and stack are placed into an (orphaned) section "_init_memory" which is given to uvm when it is no longer used. Various kernels have been converted to use this code and tested. Some boards were provided by TNF. Thanks! The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS kernels. The GENERIC kernel will also work on RPI2 using u-boot. Thanks to martin@ and aymeric@ for testing on parallella and nanosoc respectively

Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

Update the kernhist(9) kernel history code to address issues identified
in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in
the kernel and in the structures used for exporting the history data
to userland via sysctl(9). This avoids problems on some architectures
where passing a 64-bit (or larger) value to printf(3) can cause it to
process the value as multiple arguments. (This can be particularly
problematic when printf()'s format string is not a literal, since in
that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to
include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings
updated. Each format specifier now includes an explicit length
modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings
updated to replace uses of "%p" with "%#jx", and the pointer
arguments are now cast to (uintptr_t) before being subsequently cast
to (uintmax_t). This is needed to avoid compiler warnings about
casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or
"%c" format strings replaced with numeric formats; several instances
of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the
history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with
the -u option does not exist (previously, this condition was silently
ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the
data exported via sysctl(9) and exits if they do not match the values
with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional
requirements imposed on the format strings, along with several other
minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example,
uint64_t) for the history arguments. But that would require another
"rototill" of all the users in the future when we add support for an
architecture that supports a larger size. Also, the printf(3)
format
specifiers for explicitly-sized values, such as "%"PRIu64, are much
more verbose (and less aesthetically appealing, IMHO) than simply
using "%ju".
[2] I've tried very hard to find "all [the] existing users of
kernhist(9)"
but it is possible that I've missed some of them. I would be glad
to
update any stragglers that anyone identifies.
--
For some reason this single kernel seems to have outgrown its declared
size as a result of the kernhist(9) changes. Bump the size.
XXX The amount of increase may be excessive - anyone with more detailed
XXX knowledge please feel free to further adjust the value
appropriately.
--
Misssed one cast of pointer --> uintptr_t in previous kernhist(9) commit
--
And yet another one. :(
--
Use correct mark-up for NetBSD version.
--
More improvements in grammar and readability.
--
Remove a stray '"' (obvious typo) and add a couple of casts that are
probably needed.
--
And replace an instance of "%p" conversion with "%#jx"
--
Whitespace fix. Give Bl tag table a width. Fix Xr.

Make the ARM pmap use ASIDs, split TTBRs, and MP safe. This only happens for ARMv6 or later CPUs. This means that on context switch that the TLBs and caches no longer to cleaned/flushed. Also, eXecute Never (XN) protection has been added so non-exec pages can not be run. Change the page size for ARMv6+ to be 8KB while allows a L1PT to be a normal page. This means that the L1PT is not special. Use the XN support to only sync pages that are executed from.

Add a ARM_HAS_VBAR option which forces the use of the VBAR register. This allows much code to deal with vector_page mappings to be eliminated. On a BEAGLEBONE kernel, this saves 8KB of text and instructions that never have to be executed. (The PJ4B has VBAR but doesn't implement the security extensions it is part of so a method was needed to allow it use VBAR with relying on the default test for the security extensions.)

Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead but add a second argument to it to indicate whether the TLB/caches need to be flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field to see if the fixed can be skipped. Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1) or enabeld (bit = 0). With these changes, the A9 MMU can use traverse caches to do MMU tablewalks Also, make sure all memory has the shareable bit for the A9.

Use the correct (L1_S_PROT, not L2_S_PROT) macro for setting the protection of the vector page. This fixes a nasty little bug that shows up on armv7 systems when the vector page physical address changes (bit 12 of the address is cleared) and then any exception causes the system to hang.

Provide a method for attachments to specify capabilites. Add support for the PL011 to plcom. Pull across a bunch of fixes from com(4) while I'm here and do some other tidyup. Tested on a RaspberryPi. PL010 not tested. Initial commit of support for the RaspberryPI (www.raspberrypi.org) This is enough for serial console via the gpio header pins and to get to multiuser.

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

Implement sharing of vnode_t::v_interlock amongst vnodes: - Lock is shared amongst UVM objects using uvm_obj_setlock() or getnewvnode(). - Adjust vnode cache to handle unsharing, add VI_LOCKSHARE flag for that. - Use sharing in tmpfs and layerfs for underlying object. - Simplify locking in ubc_fault(). - Sprinkle some asserts. Discussed with ad@.

Apply some band-aid to pmap_activate() for PR kern/41058: There's a corner case here which can leave turds in the cache as reported in kern/41058. They're probably left over during tear-down and switching away from an exiting process. Until the root cause is identified and fixed, zap the cache when switching pmaps. This will result in a few unnecessary cache flushes, but that's better than silently corrupting data. Also remove an extraneous return statement in pmap_page_protect() which crept in during the matt-armv6 merge.

Simplify pmap_remove() a little by avoiding pmap_do_remove() layer, since possibility to skip wired mappings is not needed anymore. Apart from that, no functional differences are intended.

Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.

Change pv_entries to use SLIST. For VIPT caches, keep track of when pages are dirty so that their content can be flushed back to main memory. This is done when the page is read-only mapped by more than 1 color. Pages become when either their modified bit gets set or an unmanaged writeable page is mapped. When a page in unmapped or changed to read-only, run pmap_vac_me_harder in case the page can be mapped read-only. Thanks are given to Imre Deak for giving me the idea to assert for PVF_DIRTY.

There's really no need to switch VM contexts within cpu_switchto() as MI code always calls pmap_deactivate/pmap_activate on context switch. Instead, just record the last active lwp (or NULL if it exited) and defer switching VM context to pmap_activate(). This saves an additional function call overhead in cpu_switchto(). While here, g/c unused cpuswitch.S local .Lblock_userspace_access.

Add support for kcore headers to arm32 kernel core dumps. The kcore code is based on i386's kcore header handling. Having an asm stub for dumpsys, to dump the registers onto the stack, and then call the C code to do the memory dump is based on amd64's core dump code. This allows a successful core dump on cats. Part of fixing PR cats/18026.

Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

ARM cpu_switchto() has been partially broken since yamt-idlelwp was merged as its cache/tlb management smarts relied too heavily on pre-merge context- switch behaviour. See PR kern/36548 for one manifestation of the breakage. To address this: - Ditch the shadow pmap variables in the PCB (pagedir, l1vec, dacr, cstate) as it was too easy for them to get out of sync with the pmap. - Re-write (and fix) the convoluted cpuswitch.S cache/tlb ASM code in C. It's only slightly less efficient, but is much more readable/maintainable. - Document cpufuncs.cf_context_switch() as being C-callable. - pmap_activate() becomes a no-op if the lwp's vmspace is already active. (Good performance win, since pmap_activate() is now invoked on every context-switch, even though ARM's cpu_switchto() already does all the grunt work) XXX: Some CPU-specific armXX_context_switch() implementations (arm67, arm7tdmi, arm8) always flush the I+D caches. This should not be necessary. Someone with access to hardware (acorn32?) needs to deal with this.

In pmap_activate restore interrupts to their previous state rather than always enabling them. It's not clear if this actually caused any problems, but it seems safer to restore to the previous state in case pmap_activate is ever called with interrupts disabled.

Pull up following revision(s) (requested by matt in ticket #457): sys/arch/arm/arm32/pmap.c: revision 1.158 From Scott Allan in http://mail-index.netbsd.org/port-arm/2006/07/26/0000.html I ran into a problem when I tried to set up a mapping that started at virtual address 0xFFF00000 and was 0x00100000 long. In other words, the mapping should have gone to the end of the 32 bit address space. The mapping was made with no problem, but pmap_devmap_find_va() wouldn't find an address within the mapping. For example, if I told it to find a mapping for 0x1000 bytes at 0xFFF01000, it would try to make sure that 0xFFF01000 was greater than 0xFFF00000 and that (0xFFF01000+0x1000) was less than (0xFFF00000 +0x00100000). However, that last expression (0xFFF00000+0x00100000) wrapped around to be simply 0x00000000 so it wasn't found. This patch fixes this problem in pmap_devmap_find_va() and pmap_devmap_find_pa() by subtracting one off of the

Since pmap_page_remove() is called from pmap_page_protect(), don't modify the current pmap's pm_cstate if we have to flush the TLB, as callers of pmap_page_protect() are not required to invoke pmap_update() afterwards. Otherwise we can end up with a pm_cstate which is inconsistent with reality in the TLB, which can lead to future TLB flushes being erroneously skipped.

Just before removing the vector page mapping, switch to the kernel pmap's L1/vector page mapping so as not to pull the rug out from under ourselves.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM. Machine-dependent code is
responsible for initializing them before main() is called. Anything
that steals KVA must adjust these variables accordingly.
This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().
This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.
This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

Some ARM32_PMAP_NEW-related cleanup: * Define a new "MMU type", ARM_MMU_SA1. While the SA-1's MMU is basically compatible with the generic, the SA-1 cache does not have a write-through mode, and it is useful to know have an indication of this. * Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at compile time. We evaluate it like so: - If SA-1-style MMU is the only type configured -> 1 - If SA-1-style MMU is not configured -> 0 - Otherwise, defer to a run-time variable. If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly code can include the necessary run-time support. PMAP_INCLUDE_PTE_SYNC largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve included with the original new pmap. * In the new pmap, make pmap_pte_init_generic() check to see if the CPU has a write-back cache. If so, init the PT cache mode to C=1,B=0 to get write-through mode. Otherwise, init the PT cache mode to C=1,B=1. * Add a new pmap_pte_init_arm8(). Old pmap, same as generic. New pmap, sets page table cacheability to 0 (ARM8 has a write-back cache, but flushing it is quite expensive). * In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to C=1,B=0, since the write-back check in generic gets it wrong for ARM9, since we use write-through mode all the time on ARM9 right now. (What this really tells me is that the test for write-through cache is less than perfect, but we can fix that later.) * Add a new pmap_pte_init_sa1(). Old pmap, same as generic. New pmap, does generic initialization, then resets page table cache mode to C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.

earlier. write-back on C0 and C1 stepping (a.k.a PXA2[15]5 A0)
options XSCALE_CACHE_WRITE_{THROUGH,BACK} can override it.
for other XScale CPUs than PXA2xx, XSCALE_CACHE_WRITE_THROUGH works
same as before.

A few minor tweaks. Use pmap_free_pvs in pmap_remove, should save on the overhead of freeing each pv on it's own. Correctly set ptp when calling pmap_enter_pv, this adds more overhead, but the effect is minimal. Timings show that it increases gmake's make configure step from 2:07.90 to 2:08.90. I've more optimisations planned that should negate this increase.

Enable caching on kernel and user page tables. This saves having to do uncached memory access during VM operations (which can be quite expensive on some CPUs). We currently write-back PTEs as soon as they're modified; there is some room for optimization (to write them back in larger chunks). For PTEs in the APTE space (i.e. PTEs for pmaps that describe another process's address space), PTEs must also be evicted from the cache complete (PTEs in PTE space will be evicted durint a context switch).

From trunk: Add the brutal hack that allows us to limp along using the read/write cache line allocation policy on XScale CPUs: in pmap_enter(), if the pmap is the kernel pmap, clear the X-bit in the PTE, thus disabling read/write-allocate for managed kernel mappings. Yes, this is ugly. But it makes userland code run with r/w-allocate, which is a huge improvement on systems with low core memory performance.

Overhaul how DMA ranges work in the ARM bus_dma implementation. A new "arm32_dma_range" structure now describes a DMA window, with a system address base, bus address base, and length. In addition to providing info about which memory regions are legal for DMA, the new structure provides address translation support, as well. As before, if a tag does not list any ranges, then all addresses are considered valid, and no DMA address translation is performed. This allows us to remove a large chunk of code which was duplicated and tweaked slightly (to do the address translation) from the stock ARM bus_dma in the XScale IOP and ARM Integrator ports. Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (*de*referencing curproc is another story, but that's always been true).

In pmap_copy_page_xscale(), put the source page in the mini-data cache, as well. The mini-data cache is 2-way, so src and dst won't clobber each other, and the smallness of the cache doesn't matter, since we access each page once sequentially. While we still have to do the initial clean of the source page, this saves another 4K of main D$ pollution, and also means we don't have to do 2 cache passes after the copy is complete (i.e. we can skip the invalidation of the source page in the main cache, since it's no longer there).

If only one MMU class is configured into the kernel (based on CPU_* options), then we get the constants for that MMU class. Otherwise we indirect through varaibles set up via set_cpufuncs(). XXX The XScale bits are currently the same as the generic bits. Baby steps.

Clean up handling of the vector page on 32-bit ARM systems:
* Don't refer to VA 0, instead refer to a new variable: vector_page
* Delete the old zero_page_*() functions, replacing them with a new
one: vector_page_setprot().
* When manipulating vector page mappings in user pmaps, only do so if
the vector page is below KERNEL_BASE (if it's above KERNEL_BASE, the
vector page is mapped by the kernel pmap).
* Add a new function, arm32_vector_init(), which takes the virtual
address of the vector page (which MUST be valid when the function
is called) and a bitmask of vectors the kernel is going to take
over, and performs all vector page initialization, including setting
the V bit in the CPU Control register ("relocate vectors to high
address"), if necessary.

The target page of pmap_zero_page(), pmap_pageidlezero(), and pmap_copy_page() will never have any mappings. Therefore, it is unnecessary to do a cache clean for that page. Add assertions in #ifdef DEBUG that assert this invariant. This shaves some cycles off the frequently-called pmap_zero_page() and pmap_copy_page() (no need to look up the dst page's vm_page structure, and one less function call to clean the page).

Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

Implement pmap_growkernel for arm32 based ports. Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats. Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.

Change pmap_map_entry() to work like pmap_map_chunk(): take a pointer to the L1 table and a virtual address, and no pointer to the L2 table. The L2 table will be looked up by pmap_map_entry(), which will panic if the there is no L2 table for the requested VA. NOTE: IT IS EXTREMELY IMPORTANT THAT THE CORRECT VIRTUAL ADDRESS BE PROVIDED TO pmap_map_entry()! Notably, the code that mapped the kernel L2 tables into the kernel PT mapping L2 table were not passing actual virtual addresses, but rather offsets into the range mapped by the L2 table. I have fixed up all of these call sites, and tested the resulting kernel on both an IQ80310 and a Shark. Other portmasters should examine their pmap_map_entry() calls if their new kernels fail.

Overhaul of the ARM cache code. This is mostly a simplification pass. Rather than providing a whole slew of cache operations that aren't ever used, distill them down to some useful primitives: icache_sync_all Synchronize I-cache icache_sync_range Synchronize I-cache range dcache_wbinv_all Write-back and Invalidate D-cache dcache_wbinv_range Write-back and Invalidate D-cache range dcache_inv_range Invalidate D-cache range dcache_wb_range Write-back D-cache range idcache_wbinv_all Write-back and Invalidate D-cache, Invalidate I-cache idcache_wbinv_range Write-back and Invalidate D-cache, Invalidate I-cache range Note: This does not yet include an overhaul of the actual asm files that implement the primitives. Instead, we've provided a safe default for each CPU type, and the individual CPU types can now be optimized one at a time.

Replace most uses of pmap_pde_p with pmap_pde_page, since that is what we need later in the code.

Add a diagnostic that detects attempts to call pmap_kenter_pa with a va that is section-mapped.

When clearing the modified bit for modified emulation, don't turn caching on for a page just because we are clearing the writable bit in the PTE: this is incompatible with the way pmap_vac_me_harder works, and the code in the modified emulation handler doesn't know about recalculating the cachable attributes (nor should it, IMO). Also, if we are invalidating a page, flush its TLB entry; for some reason we were only doing this when clearing the Write or modified bits. These patches together seem to solve the random seg-faults that were still occuring occasionally under heavy paging.

On processors that support both write-through and write-back cacheing (eg ARM920), the mode in which the processor operates is governed by the use of both the PT_C and PT_B bits: PT_C=1,PT_B=1 -> Write-back PT_C=1,PT_B=0 -> Write-through To support this define pte_cache_mode (initialized to PT_C|PT_B) and use that when enabling cacheing for a page.

With a diagnostic kernel, printing out a message each time we fail to allocate a L1 pt is often enough to bring the system to its knees: so make the messages PDEBUG(0,...). However, even with this step having more than a small number of processes searching for a L1 pt can still be enough to bring the system down, since they all run at high priority and sleep for very little time, thus blocking out user code from completing. So implement an exponential backoff when waiting for a page table, so that we don't hog the CPU when memory is scarce. Tested by running a make of the C compiler with "gnumake -j30" (and plenty of swap space).

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Checking a whole host of pmap changes: Improved locking (not that we actually use it on a uniprocessor, but one day :) Removed unneeded splvm's tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E) Adopted pv entry allocation mechanism from i386. Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits. ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove. Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this. I believe this code to be stable, if anyone has any problems please shout up.

Improve the vac_me_harder function, it is now slightly faster, however pmap_enter_pv is also now slightly slower, so they appear to balance out. Note that I've some ideas in the works on how to improve the pv handling, so the slow down is short term only. Also added non-advertising licence and copyright to myself and richard.

Add a pmap_map_ptes function to map another process page table entries into the current pmap (similair to pmap_pte) but this allows multiple use of it, rather than repeated calls of pmap_pte for pte, map_ptes returns a pointer to the va where the entries were mapped so it can be reused ptes can be found by indexing into it. Update some of the functions that use pmap_pte to pmap_map_ptes. Note that there's a dummy macro for pmap_unmap_ptes, this is because at some point locking will be needed, so we need to be able to unlock them. Performance gain seems to be minimal, however long term it should help improve things. This is similair to the i386 pmap_map_ptes, however it's based on a version from Richard Earnshaw.

Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9). These calls are relatively conservative. It may be possible to optimize these a little more.

Remove pmap_kenter_pgs(). It was never really adopted by anything, and the interface itself wasn't as flexible as callers would have probably liked.
