Remove locking since it isn't needed. As soon as the 2nd uvm_map_entry in kernel_map is created, uvm_map_prepare will call pmap_growkernel and the pmap_growkernel call in uvm_km_mem_alloc will never be called again.

When using uvm_km_pgremove_intrsafe() make sure mappings are removed before returning the pages to the free pool. Otherwise, under Xen, a page which still has a writable mapping could be allocated for a PDP by another CPU and the hypervisor would refuse it (this is PR port-xen/45975). For this, move the pmap_kremove() calls inside uvm_km_pgremove_intrsafe(), and do pmap_kremove()/uvm_pagefree() in batch of (at most) 16 entries (as suggested by Chuck Silvers on tech-kern@, see also http://mail-index.netbsd.org/tech-kern/2012/02/17/msg012727.html and followups).

Add a MAP_NOSYSCALLS flag to mmap. This flag prohibits executing of system calls from the mapped region. This can be used for emulation perposed or for extra security in the case of generated code. Its implemented by adding mapping-attributes to each uvm_map_entry. These can then be queried when needed. Currently the MAP_NOSYSCALLS is only implemented for x86 but other architectures are easy to adapt; see the sys/arch/x86/x86/syscall.c patch. Port maintainers are encouraged to add them for their processor ports too. When this feature is not yet implemented for an architecture the MAP_NOSYSCALLS is simply ignored with virtually no cpu cost..

Forward some UVM from matt-nb5-mips64. Add UVM_KMF_COLORMATCH flag. When uvm_map gets passed UVM_FLAG_COLORMATCH, the align argument contains the color of the starting address to be allocated (0..colormask). When uvm_km_alloc is passed UVM_KMF_COLORMATCH (which can only be used with UVM_KMF_VAONLY), the align argument contain the color of the starting address to be allocated. Change uvm_pagermapin to use this. When mapping user pages in the kernel, if colormatch is used with the color of the starting user page then the kernel mapping will be congruent with the existing user mappings.

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.

Keep the lock around pmap_update() where required. While fixing this in ubc_fault(), rework logic to "remember" the last object of page and reduce locking overhead, since in common case pages belong to one and the same UVM object (but not always, therefore add a comment). Unlocks before pmap_update(), on removal of mappings, might cause TLB coherency issues, since on architectures like x86 and mips64 invalidation IPIs are deferred to pmap_update(). Hence, VA space might be globally visible before IPIs are sent or while they are still in-flight. OK ad@.

Remove separate mb_map. The nmbclusters is computed at boot time based on the amount of physical memory and limited by NMBCLUSTERS if present. Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.

This fixes a '"panic: malloc: out of space in kmem_map" when it's not really' testcase of mine, and one reported to me by chuq. This is likely to fix PR/35587 as well.

Better implementation of PaX MPROTECT, after looking some more into the code and not trying to use temporary solutions. Lots of comments and help from YAMAMOTO Takashi, also thanks to the PaX author for being quick to recognize that something fishy's going on. :) Hook up in mmap/vmcmd rather than (ugh!) uvm_map_protect(). Next time I suggest to commit a temporary solution just revoke my commit bit.

two changes in improve scalability:
(1) split the single list of pages allocated to a pool into three lists:
completely full, partially full, and completely empty.
there is no longer any need to traverse any list looking for a
certain type of page.
(2) replace the 8-element hash table for out-of-page page headers
with a splay tree.
these two changes (together with the recent enhancements to the wait code)
give us linear scaling for a fork+exit microbenchmark.

Introduce "top down" memory management for mmap()ed allocations. This means that the dynamic linker gets mapped in at the top of available user virtual memory (typically just below the stack), shared libraries get mapped downwards from that point, and calls to mmap() that don't specify a preferred address will get mapped in below those. This means that the heap and the mmap()ed allocations will grow towards each other, allowing one or the other to grow larger than before. Previously, the heap was limited to MAXDSIZ by the placement of the dynamic linker (and the process's rlimits) and the space available to mmap was hobbled by this reservation. This is currently only enabled via an *option* for the i386 platform (though other platforms are expected to follow). Add "options USE_TOPDOWN_VM" to your kernel config file, rerun config, and rebuild your kernel to take advantage of this. Note that the pmap_prefer() interface has not yet been modified to play nicely with this, so those platforms require a bit more work (most notably the sparc) before they can use this new memory arrangement. This change also introduces a VM_DEFAULT_ADDRESS() macro that picks the appropriate default address based on the size of the allocation or the size of the process's text segment accordingly. Several drivers and the SYSV SHM address assignment were changed to use this instead of each one picking their own "default".

Change uvm_km_kmemalloc() to accept flag UVM_KMF_NOWAIT and pass it to uvm_map(). Change uvm_map() to honnor UVM_KMF_NOWAIT. For this, change amap_extend() to take a flags parameter instead of just boolean for direction, and introduce AMAP_EXTEND_FORWARDS and AMAP_EXTEND_NOWAIT flags (AMAP_EXTEND_BACKWARDS is still defined as 0x0, to keep the code easier to read). Add a flag parameter to uvm_mapent_alloc(). This solves a problem a pool_get(PR_NOWAIT) could trigger a pool_get(PR_WAITOK) in uvm_mapent_alloc(). Thanks to Chuck Silvers, enami tsugutomo, Andrew Brown and Jason R Thorpe for feedback.

Implement backwards extension of amaps. There are three cases to deal with: Case #1 -- adjust offset: The slot offset in the aref can be decremented to cover the required size addition. Case #2 -- move pages and adjust offset: The slot offset is not large enough, but the amap contains enough inactive space *after* the mapped pages to make up the difference, so active slots are slid to the "end" of the amap, and the slot offset is, again, adjusted to cover the required size addition. This optimizes for hitting case #1 again on the next small extension. Case #3 -- reallocate, move pages, and adjust offset: There is not enough inactive space in the amap, so the arrays are reallocated, and the active pages are copied again to the "end" of the amap, and the slot offset is adjusted to cover the required size. This also optimizes for hitting case #1 on the next backwards extension. This provides the missing piece in the "forward extension of vm_map_entries" logic, so the merge failure counters have been removed. Not many applications will make any use of this at this time (except for jvms and perhaps gcc3), but a "top-down" memory allocator will use it extensively.

Add an implementation of forward merging of new map entries. Most new allocations can be merged either forwards or backwards, meaning no new entries will be added to the list, and some can even be merged in both directions, resulting in a surplus entry. This code typically reduces the number of map entries in the kernel_map by an order of magnitude or more. It also makes possible recovery from the pathological case of "5000 processes created and then killed", which leaves behind a large number of map entries. The only forward merge case not covered is the instance of an amap that has to be extended backwards (WIP). Note that this only affects processes, not the kernel (the kernel doesn't use amaps), and that merge opportunities like this come up *very* rarely, if at all. Eg, after being up for eight days, I see only three failures in this regard, and even those are most likely due to programs I'm developing to exercise this case. Code reviewed by thorpej, matt, christos, mrg, chuq, chuck, perry, tls, and probably others. I'd like to thank my mother, the Hollywood Foreign Press...

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.

introduce a new UVM fault type, VM_FAULT_WIREMAX. this is different
from VM_FAULT_WIRE in that when the pages being wired are faulted in,
the simulated fault is at the maximum protection allowed for the mapping
instead of the current protection. use this in uvm_map_pageable{,_all}()
to fix the problem where writing via ptrace() to shared libraries that
are also mapped with wired mappings in another process causes a
diagnostic panic when the wired mapping is removed.
this is a really obscure problem so it deserves some more explanation.
ptrace() writing to another process ends up down in uvm_map_extract(),
which for MAP_PRIVATE mappings (such as shared libraries) will cause
the amap to be copied or created. then the amap is made shared
(ie. the AMAP_SHARED flag is set) between the kernel and the ptrace()d
process so that the kernel can modify pages in the amap and have the
ptrace()d process see the changes. then when the page being modified
is actually faulted on, the object pages (from the shared library vnode)
is copied to a new anon page and inserted into the shared amap.
to make all the processes sharing the amap actually see the new anon
page instead of the vnode page that was there before, we need to
invalidate all the pmap-level mappings of the vnode page in the pmaps
of the processes sharing the amap, but we don't have a good way of
doing this. the amap doesn't keep track of the vm_maps which map it.
so all we can do at this point is to remove all the mappings of the
page with pmap_page_protect(), but this has the unfortunate side-effect
of removing wired mappings as well. removing wired mappings with
pmap_page_protect() is a legitimate operation, it can happen when a file
with a wired mapping is truncated. so the pmap has no way of knowing
whether a request to remove a wired mapping is normal or when it's due to
this weird situation. so the pmap has to remove the weird mapping.
the process being ptrace()d goes away and life continues. then,
much later when we go to unwire or remove the wired vm_map mapping,
we discover that the pmap mapping has been removed when it should
still be there, and we panic.
so where did we go wrong? the problem is that we don't have any way
to update just the pmap mappings that need to be updated in this
scenario. we could invent a mechanism to do this, but that is much
more complicated than this change and it doesn't seem like the right
way to go in the long run either.
the real underlying problem here is that wired pmap mappings just
aren't a good concept. one of the original properties of the pmap
design was supposed to be that all the information in the pmap could
be thrown away at any time and the VM system could regenerate it all
through fault processing, but wired pmap mappings don't allow that.
a better design for UVM would not require wired pmap mappings,
and Chuck C. and I are talking about this, but it won't be done
anytime soon, so this change will do for now.
this change has the effect of causing MAP_PRIVATE mappings to be
copied to anonymous memory when they are mlock()d, so that uvm_fault()
doesn't need to copy these pages later when called from ptrace(), thus
avoiding the call to pmap_page_protect() and the panic that results
from this when the mlock()d region is unlocked or freed. note that
this change doesn't help the case where the wired mapping is MAP_SHARED.

in uvm_map_clean(), add PGO_CLEANIT to the flags passed to an object's pager. we need to make sure that vnode pages are written to disk at least once, otherwise processes could gain access to whatever data was previously stored in disk blocks which are freshly allocated to a file.

fix locking for loaning. in general we should be looking at the page's uobject and uanon pointers rather than at the PQ_ANON flag to determine which lock to hold, since PQ_ANON can be clear even when the anon's lock is the one which we should hold (if the page was loaned from an object and then freed by the object).

- Add a new vnode flag VEXECMAP, which indicates that a vnode has executable mappings. Stop overloading VTEXT for this purpose (VTEXT also has another meaning). - Rename vn_marktext() to vn_markexec(), and use it when executable mappings of a vnode are established. - In places where we want to set VTEXT, set it in v_flag directly, rather than making a function call to do this (it no longer makes sense to use a function call, since we no longer overload VTEXT with VEXECMAP's meaning). VEXECMAP suggested by Chuq Silvers.

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.

Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.

Don't uvm_deallocate() the address space in exit1(). The address space is already torn down in uvmspace_free() when the vmspace refrence count reaches 0. Move the shmexit() call into uvmspace_free(). Note that there is a beneficial side-effect of deferring the unmap to uvmspace_free() -- on systems where TLB invalidations are particularly expensive, the unmapping of the address space won't have to cause TLB invalidations; uvmspace_free() is going to be run in a context other than the exiting process's, so the "pmap is active" test will evaluate to FALSE in the pmap module.

in uvm_map_clean(), fix the case where the start offset is within the last entry in the map. the old code would walk around the end of the linked list, through the header entry, and keep going from the first map entry until it found a gap in the map, at which point it would return an error. if the map had no gaps then it would loop forever. reported by k-abe@cs.utah.edu. while I'm here, clean up this function a bit. also, use MIN() instead of min(), since the latter takes arguments of type "int" but we're passing it values of type "vaddr_t", which can be a larger size.

Page scanner improvements, behavior is actually a bit more like Mach VM's now. Specific changes: - Pages now need not have all of their mappings removed before being put on the inactive list. They only need to have the "referenced" attribute cleared. This makes putting pages onto the inactive list much more efficient. In order to eliminate redundant clearings of "refrenced", callers of uvm_pagedeactivate() must now do this themselves. - When checking the "modified" attribute for a page (for clearing PG_CLEAN), make sure to only do it if PG_CLEAN is currently set on the page (saves a potentially expensive pmap operation). - When scanning the inactive list, if a page is referenced, reactivate it (this part was actually added in uvm_pdaemon.c,v 1.27). This now works properly now that pages on the inactive list are allowed to have mappings. - When scanning the inactive list and considering a page for freeing, remove all mappings, and then check the "modified" attribute if the page is marked PG_CLEAN. - When scanning the active list, if the page was referenced since its last sweep by the scanner, don't deactivate it. (This part was actually added in uvm_pdaemon.c,v 1.28.) These changes greatly improve interactive performance during moderate to high memory and I/O load.

When an unconditional save is required, the "check" value passed should be map->hint (and the compiler will optimize the test away). When deleting a map entry, the new SAVE_HINT() will only change the hint if the entry being deleted was the hint value (thus preserving any meaningful hint that may have been there previously, rather than stomping on it). - Add a missing hint update when deleting the map entry in uvm_map_entry_unlink().

Changes necessary to implement pre-zero'ing of pages in the idle loop: - Make page free lists have two actual queues: known-zero pages and pages with unknown contents. - Implement uvm_pageidlezero(). This function attempts to zero up to the target number of pages until the target has been reached (currently target is `all free pages') or until whichqs becomes non-zero (indicating that a process is ready to run). - Define a new hook for the pmap module for pre-zero'ing pages. This is used to zero the pages using uncached access. This allows us to zero as many pages as we want without polluting the cache. In order to use this feature, each platform must add the appropropriate glue in their idle loop.

Merge parts of chs-ubc2 into the trunk: Add a new type voff_t (defined as a synonym for off_t) to describe offsets into uvm objects, and update the appropriate interfaces to use it, the most visible effect being the ability to mmap() file offsets beyond the range of a vaddr_t. Originally by Chuck Silvers; blame me for problems caused by merging this into non-UBC.

Add some more meat to madvise(2): * Implement MADV_DONTNEED: deactivate pages in the specified range, semantics similar to Solaris's MADV_DONTNEED. * Add MADV_FREE: free pages and swap resources associated with the specified range, causing the range to be reloaded from backing store (vnodes) or zero-fill (anonymous), semantics like FreeBSD's MADV_FREE and like Digital UNIX's MADV_DONTNEED (isn't it SO GREAT that madvise(2) isn't standardized!?) As part of this, move the non-map-modifying advice handling out of uvm_map_advise(), and into sys_madvise(). As another part, implement general amap cleaning in uvm_map_clean(), and change uvm_map_clean() to only push dirty pages to disk if PGO_CLEANIT is set in its flags (and update sys___msync13() accordingly). XXX Add a patchable global "amap_clean_works", defaulting to 1, which can disable the amap cleaning code, just in case problems are unearthed; this gives a developer/user a quick way to recover and send a bug report (e.g. boot into DDB and change the value). XXX Still need to implement a real uao_flush(). XXX Need to update the manual page. With these changes, rebuilding libc will automatically cause the new malloc(3) to use MADV_FREE to actually release pages and swap resources when it decides that can be done.

Modify uvm_map_pageable() and uvm_map_pageable_all() to follow POSIX 1003.1b semantics. That is, regardless of the number of mlock/mlockall calls, an munlock/munlockall actually unlocks the region (i.e. sets wiring count to 0). Add a comment describing why uvm_map_pageable() should not be used for transient page wirings (e.g. for physio) -- note, it's currently only (ab)used in this way by a few pieces of code which are known to be broken, i.e. the Amiga and Atari pmaps, and i386 and pc532 if PMAP_NEW is not used. The i386 GDT code uses uvm_map_pageable(), but in a safe way, and could be trivially converted to use uvm_fault_wire() instead.

Simplify the last even more; We downgraded to a shared (read) lock, so setting recursive has no effect! The kernel lock manager doesn't allow an exclusive recursion into a shared lock. This situation must simply be avoided. The only place where this might be a problem is the (ab)use of uvm_map_pageable() in the Utah-derived pmaps for m68k (they should either toss the iffy scheme they use completely, or use something like uvm_fault_wire()). In addition, once we have looped over uvm_fault_wire(), only upgrade to an exclusive (write) lock if we need to modify the map again (i.e. wiring a page failed).

Clean up the locking mess in uvm_map_pageable() a little... Most importantly, don't unlock a kernel map (!!!) and then relock it later; a recursive lock, as it used in the user map case, is fine. Also, don't change map entries while only holding a read lock on the map. Instead, if we fail to wire a page, clear recursive locking, and upgrade back to a write lock before dropping the wiring count on the remaining map entries.

Upon further investigation, in uvm_map_pageable(), entry->protection is the right access_type to pass to uvm_fault_wire(). This way, if the entry has VM_PROT_WRITE, and the entry is marked COW, the copy will happen immediately in uvm_fault(), as if the access were performed.

Change the vm_map's "entries_pageable" member to a r/o flags member, which has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable", not "allocate vm_map_entry's from non-static pool", so update all map creations to reflect that. INTRSAFE maps are maps that are used in interrupt context (e.g. kmem_map, mb_map), and thus use the static map entry pool (XXX as does kernel_map, for now). This will eventually change now these maps are locked, as well.

Add support for multiple memory free lists. There is at least one default free list, and 0 - N additional free list, in order of descending priority. A new page allocation function, uvm_pagealloc_strat(), has been added, providing three page allocation strategies: - normal: high -> low priority free list walk, taking the page off the first free list that has one. - only: attempt to allocate a page only from the specified free list, failing if that free list has none available. - fallback: if `only' fails, fall back on `normal'. uvm_pagealloc(...) is provided for normal use (and is a synonym for uvm_pagealloc_strat(..., UVM_PGA_STRAT_NORMAL, 0); the free list argument is ignored for the `normal' case). uvm_page_physload() now specified which free list the pages will be loaded onto. This means that some platforms which have multiple physical memory segments may define additional vm_physsegs if they wish to break individual physical segments into differing priorities. Machine-dependent code must define _at least_ the following constants in <machine/vmparam.h>: VM_NFREELIST: the number of free lists the system will have VM_FREELIST_DEFAULT: the default freelist (should always be 0, but is defined in machdep code so that it's with all of the other free list-related constants). Additional free list names may be defined by machine-dependent code, but they will only be used by machine-dependent code (e.g. for loading the vm_physsegs).

rework the copy inheritance case of fork. the old way did not handle the very rare case of shared mappings that have amap's attached in a reasonable way -- this is not currently causing any problems, but i fixed it anyway. update the comment in this section of code and also be smarter about avoiding needless calls to pmap_protect().

move pdhist initialisation to the same place as maphist. also, declare the history buffers are "struct uvm_history_ent" to ensure proper alignment (eg, alpha). this fixes a boottime panic when the pdhist was used before it had been initialised.
