760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * There are three memory contexts: Host Context (HC), Guest Context (GC)
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * and intermediate context. When talking about paging HC can also be refered to
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * as "host paging", and GC refered to as "shadow paging".
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync *
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * We define three basic paging modes: 32-bit, PAE and AMD64. The host paging mode
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * is defined by the host operating system. The mode used in the shadow paging mode
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * depends on the host paging mode and what the mode the guest is currently in. The
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * following relation between the two is defined:

1999ae03c34840fa4d712fd2e020120b2cb7182avboxsync * Because of guest context mappings requires PDPT and PML4 entries to allow
9347f1987dfb760943aba5a9ef094c6066901be3vboxsync * writing on AMD64, the two upper levels will have fixed flags whatever the
1999ae03c34840fa4d712fd2e020120b2cb7182avboxsync * guest is thinking of using there. So, when shadowing the PD level we will
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * calculate the effective flags of PD and all the higher levels. In legacy
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * PAE mode this only applies to the PWT and PCD bits (the rest are

760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * to provide different mappings of the switcher code. All guest mappings are also

ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * The differences between legacy PAE and long mode PAE are:
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * -# PDPE bits 1, 2, 5 and 6 are defined differently. In leagcy mode they are
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * all marked down as must-be-zero, while in long mode 1, 2 and 5 have the
addc480d0d7650db6323467bbdab6c21836a2928vboxsync * usual meanings while 6 is ignored (AMD). This means that upon switching to
addc480d0d7650db6323467bbdab6c21836a2928vboxsync * legacy PAE mode we'll have to clear these bits and when going to long mode
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * they must be set. This applies to both intermediate and shadow contexts,
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * however we don't need to do it for the intermediate one since we're

8de98485a60eb742b1d720a8cb9747dc03e821a8vboxsync * We currently implement three types of virtual access handlers: ALL, WRITE
8de98485a60eb742b1d720a8cb9747dc03e821a8vboxsync * and HYPERVISOR (WRITE). See PGMVIRTHANDLERTYPE for some more details.

faa31dfcb46e5e2fb9c2bf224d113a0ca136ddecvboxsync * The HYPERVISOR access handlers is kept in a separate tree since it doesn't apply
8de98485a60eb742b1d720a8cb9747dc03e821a8vboxsync * to physical pages (PGMTREES::HyperVirtHandlers) and only needs to be consulted in
8de98485a60eb742b1d720a8cb9747dc03e821a8vboxsync * a special \#PF case. The ALL and WRITE are in the PGMTREES::VirtHandlers tree, the
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * rest of this section is going to be about these handlers.
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync *
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * We'll go thru the life cycle of a handler and try make sense of it all, don't know
ec21c063515d0931111f0c1f8d6f4bc8e7a6c882vboxsync * how successfull this is gonna be...
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync *
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * 1. A handler is registered thru the PGMR3HandlerVirtualRegister and
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * PGMHandlerVirtualRegisterEx APIs. We check for conflicting virtual handlers
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * and create a new node that is inserted into the AVL tree (range key). Then
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * a full PGM resync is flagged (clear pool, sync cr3, update virtual bit of PGMPAGE).
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync *
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * 2. The following PGMSyncCR3/SyncCR3 operation will first make invoke HandlerVirtualUpdate.
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync *
4ace9bce00c6d792391a0e064131716659e3a922vboxsync * 2a. HandlerVirtualUpdate will will lookup all the pages covered by virtual handlers
760446f710619a9daa6cedc7f0601f49e4ea3442vboxsync * via the current guest CR3 and update the physical page -> virtual handler
* translation. Needless to say, this doesn't exactly scale very well. If any changes
* are detected, it will flag a virtual bit update just like we did on registration.
* PGMPHYS pages with changes will have their virtual handler state reset to NONE.
*
* 2b. The virtual bit update process will iterate all the pages covered by all the
* virtual handlers and update the PGMPAGE virtual handler state to the max of all
* virtual handlers on that page.
*
* 2c. Back in SyncCR3 we will now flush the entire shadow page cache to make sure
* we don't miss any alias mappings of the monitored pages.
*
* 2d. SyncCR3 will then proceed with syncing the CR3 table.
*
* 3. \#PF(np,read) on a page in the range. This will cause it to be synced
* read-only and resumed if it's a WRITE handler. If it's an ALL handler we
* will call the handlers like in the next step. If the physical mapping has
* changed we will - some time in the future - perform a handler callback
* (optional) and update the physical -> virtual handler cache.
*
* 4. \#PF(,write) on a page in the range. This will cause the handler to
* be invoked.
*
* 5. The guest invalidates the page and changes the physical backing or
* unmaps it. This should cause the invalidation callback to be invoked
* (it might not yet be 100% perfect). Exactly what happens next... is
* this where we mess up and end up out of sync for a while?
*
* 6. The handler is deregistered by the client via PGMHandlerVirtualDeregister.
* We will then set all PGMPAGEs in the physical -> virtual handler cache for
* this handler to NONE and trigger a full PGM resync (basically the same
* as int step 1). Which means 2 is executed again.
*
*
* @subsubsection sub_sec_pgm_handler_virt_todo TODOs
*
* There is a bunch of things that needs to be done to make the virtual handlers
* work 100% correctly and work more efficiently.
*
* The first bit hasn't been implemented yet because it's going to slow the
* whole mess down even more, and besides it seems to be working reliably for
* our current uses. OTOH, some of the optimizations might end up more or less
* implementing the missing bits, so we'll see.
*
* On the optimization side, the first thing to do is to try avoid unnecessary
* cache flushing. Then try team up with the shadowing code to track changes
* in mappings by means of access to them (shadow in), updates to shadows pages,
* invlpg, and shadow PT discarding (perhaps).
*
* Some idea that have popped up for optimization for current and new features:
* - bitmap indicating where there are virtual handlers installed.
* (4KB => 2**20 pages, page 2**12 => covers 32-bit address space 1:1!)
* - Further optimize this by min/max (needs min/max avl getters).
* - Shadow page table entry bit (if any left)?

* zero pages and general page sharing.
* - Moving or mirroring a VM onto a different physical machine.
*
*
* @subsection subsec_pgmPhys_Definitions Definitions
*
* Allocation chunk - A RTR0MemObjAllocPhysNC object and the tracking
* machinery assoicated with it.
*
*
*
*
* @subsection subsec_pgmPhys_AllocPage Allocating a page.
*
* Initially we map *all* guest memory to the (per VM) zero page, which
* means that none of the read functions will cause pages to be allocated.
*
* Exception, access bit in page tables that have been shared. This must
* be handled, but we must also make sure PGMGst*Modify doesn't make
* unnecessary modifications.
*
* Allocation points:
* - PGMPhysSimpleWriteGCPhys and PGMPhysWrite.
* - Replacing a zero page mapping at \#PF.
* - Replacing a shared page mapping at \#PF.
* - ROM registration (currently MMR3RomRegister).
* - VM restore (pgmR3Load).
*
* For the first three it would make sense to keep a few pages handy
* until we've reached the max memory commitment for the VM.
*
* For the ROM registration, we know exactly how many pages we need
* and will request these from ring-0. For restore, we will save
* the number of non-zero pages in the saved state and allocate
* them up front. This would allow the ring-0 component to refuse
* the request if the isn't sufficient memory available for VM use.
*
* Btw. for both ROM and restore allocations we won't be requiring
* zeroed pages as they are going to be filled instantly.
*
*
* @subsection subsec_pgmPhys_FreePage Freeing a page
*
* There are a few points where a page can be freed:
* - After being replaced by the zero page.
* - After being replaced by a shared page.
* - After being ballooned by the guest additions.
* - At reset.
* - At restore.
*
* When freeing one or more pages they will be returned to the ring-0
* component and replaced by the zero page.
*
* The reasoning for clearing out all the pages on reset is that it will
* return us to the exact same state as on power on, and may thereby help
* us reduce the memory load on the system. Further it might have a
* (temporary) positive influence on memory fragmentation (@see subsec_pgmPhys_Fragmentation).
*
* On restore, as mention under the allocation topic, pages should be
* freed / allocated depending on how many is actually required by the
* new VM state. The simplest approach is to do like on reset, and free
* all non-ROM pages and then allocate what we need.
*
* A measure to prevent some fragmentation, would be to let each allocation
* chunk have some affinity towards the VM having allocated the most pages
* from it. Also, try make sure to allocate from allocation chunks that
* are almost full. Admittedly, both these measures might work counter to
* our intentions and its probably not worth putting a lot of effort,
* cpu time or memory into this.
*
*
* @subsection subsec_pgmPhys_SharePage Sharing a page
*
* The basic idea is that there there will be a idle priority kernel
* thread walking the non-shared VM pages hashing them and looking for
* pages with the same checksum. If such pages are found, it will compare
* them byte-by-byte to see if they actually are identical. If found to be
* identical it will allocate a shared page, copy the content, check that
* the page didn't change while doing this, and finally request both the
* VMs to use the shared page instead. If the page is all zeros (special
* checksum and byte-by-byte check) it will request the VM that owns it
* to replace it with the zero page.
*
* To make this efficient, we will have to make sure not to try share a page
* that will change its contents soon. This part requires the most work.
* A simple idea would be to request the VM to write monitor the page for
* a while to make sure it isn't modified any time soon. Also, it may
* make sense to skip pages that are being write monitored since this
* information is readily available to the thread if it works on the
* per-VM guest memory structures (presently called PGMRAMRANGE).
*
*
* @subsection subsec_pgmPhys_Fragmentation Fragmentation Concerns and Counter Measures
*
* The pages are organized in allocation chunks in ring-0, this is a necessity
* if we wish to have an OS agnostic approach to this whole thing. (On Linux we
* could easily work on a page-by-page basis if we liked. Whether this is possible
* or efficient on NT I don't quite know.) Fragmentation within these chunks may
* become a problem as part of the idea here is that we wish to return memory to
* the host system.
*
* For instance, starting two VMs at the same time, they will both allocate the
* guest memory on-demand and if permitted their page allocations will be
* intermixed. Shut down one of the two VMs and it will be difficult to return
* any memory to the host system because the page allocation for the two VMs are
* mixed up in the same allocation chunks.
*
* To further complicate matters, when pages are freed because they have been
* ballooned or become shared/zero the whole idea is that the page is supposed
* to be reused by another VM or returned to the host system. This will cause
* allocation chunks to contain pages belonging to different VMs and prevent
* returning memory to the host when one of those VM shuts down.
*
* The only way to really deal with this problem is to move pages. This can
* either be done at VM shutdown and or by the idle priority worker thread
* that will be responsible for finding sharable/zero pages. The mechanisms
* involved for coercing a VM to move a page (or to do it for it) will be
* the same as when telling it to share/zero a page.
*
*
* @subsection subsec_pgmPhys_Tracking Tracking Structures And Their Cost
*
* There's a difficult balance between keeping the per-page tracking structures
* (global and guest page) easy to use and keeping them from eating too much
* memory. We have limited virtual memory resources available when operating in
* 32-bit kernel space (on 64-bit there'll it's quite a different story). The
* tracking structures will be attemted designed such that we can deal with up
* to 32GB of memory on a 32-bit system and essentially unlimited on 64-bit ones.
*
*
* @subsubsection subsubsec_pgmPhys_Tracking_Kernel Kernel Space
*
* @see pg_GMM
*
* @subsubsection subsubsec_pgmPhys_Tracking_PerVM Per-VM
*
* Fixed info is the physical address of the page (HCPhys) and the page id
* (described above). Theoretically we'll need 48(-12) bits for the HCPhys part.
* Today we've restricting ourselves to 40(-12) bits because this is the current
* restrictions of all AMD64 implementations (I think Barcelona will up this
* to 48(-12) bits, not that it really matters) and I needed the bits for
* tracking mappings of a page. 48-12 = 36. That leaves 28 bits, which means a
* decent range for the page id: 2^(28+12) = 1024TB.
*
* In additions to these, we'll have to keep maintaining the page flags as we
* currently do. Although it wouldn't harm to optimize these quite a bit, like
* for instance the ROM shouldn't depend on having a write handler installed
* in order for it to become read-only. A RO/RW bit should be considered so
* that the page syncing code doesn't have to mess about checking multiple
* flag combinations (ROM || RW handler || write monitored) in order to
* figure out how to setup a shadow PTE. But this of course, is second
* priority at present. Current this requires 12 bits, but could probably
* be optimized to ~8.
*
* Then there's the 24 bits used to track which shadow page tables are
* currently mapping a page for the purpose of speeding up physical
* access handlers, and thereby the page pool cache. More bit for this
* purpose wouldn't hurt IIRC.
*
* Then there is a new bit in which we need to record what kind of page
* this is, shared, zero, normal or write-monitored-normal. This'll
* require 2 bits. One bit might be needed for indicating whether a
* write monitored page has been written to. And yet another one or
* two for tracking migration status. 3-4 bits total then.
*
* Whatever is left will can be used to record the sharabilitiy of a
* page. The page checksum will not be stored in the per-VM table as
* the idle thread will not be permitted to do modifications to it.
* It will instead have to keep its own working set of potentially
* shareable pages and their check sums and stuff.
*
* For the present we'll keep the current packing of the
* PGMRAMRANGE::aHCPhys to keep the changes simple, only of course,
* we'll have to change it to a struct with a total of 128-bits at
* our disposal.
*
* The initial layout will be like this:
* @verbatim
RTHCPHYS HCPhys; The current stuff.
63:40 Current shadow PT tracking stuff.
39:12 The physical page frame number.
11:0 The current flags.
uint32_t u28PageId : 28; The page id.
uint32_t u2State : 2; The page state { zero, shared, normal, write monitored }.
uint32_t fWrittenTo : 1; Whether a write monitored page was written to.
uint32_t u1Reserved : 1; Reserved for later.
uint32_t u32Reserved; Reserved for later, mostly sharing stats.
@endverbatim
*
* The final layout will be something like this:
* @verbatim
RTHCPHYS HCPhys; The current stuff.
63:48 High page id (12+).
47:12 The physical page frame number.
11:0 Low page id.
uint32_t fReadOnly : 1; Whether it's readonly page (rom or monitored in some way).
uint32_t u3Type : 3; The page type {RESERVED, MMIO, MMIO2, ROM, shadowed ROM, RAM}.
uint32_t u2PhysMon : 2; Physical access handler type {none, read, write, all}.
uint32_t u2VirtMon : 2; Virtual access handler type {none, read, write, all}..
uint32_t u2State : 2; The page state { zero, shared, normal, write monitored }.
uint32_t fWrittenTo : 1; Whether a write monitored page was written to.
uint32_t u20Reserved : 20; Reserved for later, mostly sharing stats.
uint32_t u32Tracking; The shadow PT tracking stuff, roughly.
@endverbatim
*
* Cost wise, this means we'll double the cost for guest memory. There isn't anyway
* around that I'm afraid. It means that the cost of dealing out 32GB of memory
* to one or more VMs is: (32GB >> PAGE_SHIFT) * 16 bytes, or 128MBs. Or another
* example, the VM heap cost when assigning 1GB to a VM will be: 4MB.
*
* A couple of cost examples for the total cost per-VM + kernel.
* 32-bit Windows and 32-bit linux:
* 1GB guest ram, 256K pages: 4MB + 2MB(+) = 6MB
* 4GB guest ram, 1M pages: 16MB + 8MB(+) = 24MB
* 32GB guest ram, 8M pages: 128MB + 64MB(+) = 192MB
* 64-bit Windows and 64-bit linux:
* 1GB guest ram, 256K pages: 4MB + 3MB(+) = 7MB
* 4GB guest ram, 1M pages: 16MB + 12MB(+) = 28MB
* 32GB guest ram, 8M pages: 128MB + 96MB(+) = 224MB
*
* UPDATE - 2007-09-27:
* Will need a ballooned flag/state too because we cannot
* trust the guest 100% and reporting the same page as ballooned more
* than once will put the GMM off balance.
*
*
* @subsection subsec_pgmPhys_Serializing Serializing Access
*
* Initially, we'll try a simple scheme:
*
* - The per-VM RAM tracking structures (PGMRAMRANGE) is only modified
* by the EMT thread of that VM while in the pgm critsect.
* - Other threads in the VM process that needs to make reliable use of
* the per-VM RAM tracking structures will enter the critsect.
* - No process external thread or kernel thread will ever try enter
* the pgm critical section, as that just won't work.
* - The idle thread (and similar threads) doesn't not need 100% reliable
* data when performing it tasks as the EMT thread will be the one to
* do the actual changes later anyway. So, as long as it only accesses
* the main ram range, it can do so by somehow preventing the VM from
* being destroyed while it works on it...
*
* - The over-commitment management, including the allocating/freeing
* chunks, is serialized by a ring-0 mutex lock (a fast one since the
* more mundane mutex implementation is broken on Linux).
* - A separeate mutex is protecting the set of allocation chunks so
* that pages can be shared or/and freed up while some other VM is
* allocating more chunks. This mutex can be take from under the other
* one, but not the otherway around.
*
*
* @subsection subsec_pgmPhys_Request VM Request interface
*
* When in ring-0 it will become necessary to send requests to a VM so it can
* for instance move a page while defragmenting during VM destroy. The idle
* thread will make use of this interface to request VMs to setup shared
* pages and to perform write monitoring of pages.
*
* I would propose an interface similar to the current VMReq interface, similar
* in that it doesn't require locking and that the one sending the request may
* wait for completion if it wishes to. This shouldn't be very difficult to
* realize.
*
* The requests themselves are also pretty simple. They are basically:
* -# Check that some precondition is still true.
* -# Do the update.
* -# Update all shadow page tables involved with the page.
*
* The 3rd step is identical to what we're already doing when updating a
* physical handler, see pgmHandlerPhysicalSetRamFlagsAndFlushShadowPTs.
*
*
*
* @section sec_pgmPhys_MappingCaches Mapping Caches
*
* In order to be able to map in and out memory and to be able to support
* guest with more RAM than we've got virtual address space, we'll employing
* a mapping cache. There is already a tiny one for GC (see PGMGCDynMapGCPageEx)
* and we'll create a similar one for ring-0 unless we decide to setup a dedicate
* memory context for the HWACCM execution.
*
*
* @subsection subsec_pgmPhys_MappingCaches_R3 Ring-3
*
* We've considered implementing the ring-3 mapping cache page based but found
* that this was bother some when one had to take into account TLBs+SMP and
* portability (missing the necessary APIs on several platforms). There were
* also some performance concerns with this approach which hadn't quite been
* worked out.
*
* Instead, we'll be mapping allocation chunks into the VM process. This simplifies
* matters greatly quite a bit since we don't need to invent any new ring-0 stuff,
* only some minor RTR0MEMOBJ mapping stuff. The main concern here is that mapping
* compared to the previous idea is that mapping or unmapping a 1MB chunk is more
* costly than a single page, although how much more costly is uncertain. We'll
* try address this by using a very big cache, preferably bigger than the actual
* VM RAM size if possible. The current VM RAM sizes should give some idea for
* 32-bit boxes, while on 64-bit we can probably get away with employing an
* unlimited cache.
*
* The cache have to parts, as already indicated, the ring-3 side and the
* ring-0 side.
*
* The ring-0 will be tied to the page allocator since it will operate on the
* memory objects it contains. It will therefore require the first ring-0 mutex
* discussed in @ref subsec_pgmPhys_Serializing. We
* some double house keeping wrt to who has mapped what I think, since both
* VMMR0.r0 and RTR0MemObj will keep track of mapping relataions
*
* The ring-3 part will be protected by the pgm critsect. For simplicity, we'll
* require anyone that desires to do changes to the mapping cache to do that
* from within this critsect. Alternatively, we could employ a separate critsect
* for serializing changes to the mapping cache as this would reduce potential
* contention with other threads accessing mappings unrelated to the changes
* that are in process. We can see about this later, contention will show
* up in the statistics anyway, so it'll be simple to tell.
*
* The organization of the ring-3 part will be very much like how the allocation
* chunks are organized in ring-0, that is in an AVL tree by chunk id. To avoid
* having to walk the tree all the time, we'll have a couple of lookaside entries
* like in we do for I/O ports and MMIO in IOM.
*
* The simplified flow of a PGMPhysRead/Write function:
* -# Enter the PGM critsect.
* -# Lookup GCPhys in the ram ranges and get the Page ID.
* -# Calc the Allocation Chunk ID from the Page ID.
* -# Check the lookaside entries and then the AVL tree for the Chunk ID.
* If not found in cache:
* -# Call ring-0 and request it to be mapped and supply
* a chunk to be unmapped if the cache is maxed out already.
* -# Insert the new mapping into the AVL tree (id + R3 address).
* -# Update the relevant lookaside entry and return the mapping address.
* -# Do the read/write according to monitoring flags and everything.
* -# Leave the critsect.
*
*
* @section sec_pgmPhys_Fallback Fallback
*
* Current all the "second tier" hosts will not support the RTR0MemObjAllocPhysNC
* API and thus require a fallback.
*
* So, when RTR0MemObjAllocPhysNC returns VERR_NOT_SUPPORTED the page allocator
* will return to the ring-3 caller (and later ring-0) and asking it to seed
* the page allocator with some fresh pages (VERR_GMM_SEED_ME). Ring-3 will
* then perform an SUPPageAlloc(cbChunk >> PAGE_SHIFT) call and make a
* "SeededAllocPages" call to ring-0.
*
* The first time ring-0 sees the VERR_NOT_SUPPORTED failure it will disable
* all page sharing (zero page detection will continue). It will also force
* all allocations to come from the VM which seeded the page. Both these
* measures are taken to make sure that there will never be any need for
* mapping anything into ring-3 - everything will be mapped already.
*
* Whether we'll continue to use the current MM locked memory management
* for this I don't quite know (I'd prefer not to and just ditch that all
* togther), we'll see what's simplest to do.
*
*
