31 | *
|
---|
32 | * There are three memory contexts: Host Context (HC), Guest Context (GC)
|
---|
33 | * and intermediate context. When talking about paging HC can also be refered to
|
---|
34 | * as "host paging", and GC refered to as "shadow paging".
|
---|
35 | *
|
---|
36 | * We define three basic paging modes: 32-bit, PAE and AMD64. The host paging mode
|
---|
37 | * is defined by the host operating system. The mode used in the shadow paging mode
|
---|
38 | * depends on the host paging mode and what the mode the guest is currently in. The
|
---|
39 | * following relation between the two is defined:
|
---|
40 | *
|
---|

|
---|
61 | * [..]
|
---|
62 | *
|
---|
63 | * Because of guest context mappings requires PDPT and PML4 entries to allow
|
---|
64 | * writing on AMD64, the two upper levels will have fixed flags whatever the
|
---|
65 | * guest is thinking of using there. So, when shadowing the PD level we will
|
---|
66 | * calculate the effective flags of PD and all the higher levels. In legacy
|
---|
67 | * PAE mode this only applies to the PWT and PCD bits (the rest are
|
---|
68 | * ignored/reserved/MBZ). We will ignore those bits for the present.

72 | * @section sec_pgm_int The Intermediate Memory Context
|
---|
73 | *
|
---|
74 | * The world switch goes thru an intermediate memory context which purpose it is
|
---|
75 | * to provide different mappings of the switcher code. All guest mappings are also
|
---|
76 | * present in this context.
|
---|
77 | *
|
---|
78 | * The switcher code is mapped at the same location as on the host, at an
|
---|
79 | * identity mapped location (physical equals virtual address), and at the
|
---|
80 | * hypervisor location. The identity mapped location is for when the world
|
---|
81 | * switches that involves disabling paging.
|
---|
82 | *
|
---|
83 | * PGM maintain page tables for 32-bit, PAE and AMD64 paging modes. This
|
---|
84 | * simplifies switching guest CPU mode and consistency at the cost of more
|
---|
85 | * code to do the work. All memory use for those page tables is located below
|
---|
86 | * 4GB (this includes page tables for guest context mappings).

|
---|
90 | *
|
---|
91 | * During assignment and relocation of a guest context mapping the intermediate
|
---|
92 | * memory context is used to verify the new location.
|
---|
93 | *
|
---|
94 | * Guest context mappings are currently restricted to below 4GB, for reasons
|
---|
95 | * of simplicity. This may change when we implement AMD64 support.

|
---|
103 | *
|
---|
104 | * The differences between legacy PAE and long mode PAE are:
|
---|
105 | * -# PDPE bits 1, 2, 5 and 6 are defined differently. In leagcy mode they are
|
---|
106 | * all marked down as must-be-zero, while in long mode 1, 2 and 5 have the
|
---|
107 | * usual meanings while 6 is ignored (AMD). This means that upon switching to
|
---|
108 | * legacy PAE mode we'll have to clear these bits and when going to long mode
|
---|
109 | * they must be set. This applies to both intermediate and shadow contexts,
|
---|
110 | * however we don't need to do it for the intermediate one since we're
|
---|
111 | * executing with CR0.WP at that time.
|
---|
112 | * -# CR3 allows a 32-byte aligned address in legacy mode, while in long mode
|
---|
113 | * a page aligned one is required.

126 | * @subsection sec_pgm_handlers_virt Virtual Access Handlers
|
---|
127 | *
|
---|
128 | * We currently implement three types of virtual access handlers: ALL, WRITE
|
---|
129 | * and HYPERVISOR (WRITE). See PGMVIRTHANDLERTYPE for some more details.
|
---|
130 | *
|
---|
131 | * The HYPERVISOR access handlers is kept in a separate tree since it doesn't apply
|
---|
132 | * to physical pages (PGMTREES::HyperVirtHandlers) and only needs to be consulted in
|
---|
133 | * a special \#PF case. The ALL and WRITE are in the PGMTREES::VirtHandlers tree, the
|
---|
134 | * rest of this section is going to be about these handlers.
|
---|
135 | *
|
---|
136 | * We'll go thru the life cycle of a handler and try make sense of it all, don't know
|
---|
137 | * how successfull this is gonna be...
|
---|
138 | *
|
---|
139 | * 1. A handler is registered thru the PGMR3HandlerVirtualRegister and
|
---|
140 | * PGMHandlerVirtualRegisterEx APIs. We check for conflicting virtual handlers
|
---|
141 | * and create a new node that is inserted into the AVL tree (range key). Then
|
---|
142 | * a full PGM resync is flagged (clear pool, sync cr3, update virtual bit of PGMPAGE).
|
---|
143 | *
|
---|
144 | * 2. The following PGMSyncCR3/SyncCR3 operation will first make invoke HandlerVirtualUpdate.
|
---|
145 | *
|
---|
146 | * 2a. HandlerVirtualUpdate will will lookup all the pages covered by virtual handlers
|
---|
147 | * via the current guest CR3 and update the physical page -> virtual handler
|
---|
148 | * translation. Needless to say, this doesn't exactly scale very well. If any changes
|
---|
149 | * are detected, it will flag a virtual bit update just like we did on registration.
|
---|
150 | * PGMPHYS pages with changes will have their virtual handler state reset to NONE.
|
---|
151 | *
|
---|
152 | * 2b. The virtual bit update process will iterate all the pages covered by all the
|
---|
153 | * virtual handlers and update the PGMPAGE virtual handler state to the max of all
|
---|
154 | * virtual handlers on that page.
|
---|
155 | *
|
---|
156 | * 2c. Back in SyncCR3 we will now flush the entire shadow page cache to make sure
|
---|
157 | * we don't miss any alias mappings of the monitored pages.
|
---|
158 | *
|
---|
159 | * 2d. SyncCR3 will then proceed with syncing the CR3 table.
|
---|
160 | *
|
---|
161 | * 3. \#PF(np,read) on a page in the range. This will cause it to be synced
|
---|
162 | * read-only and resumed if it's a WRITE handler. If it's an ALL handler we
|
---|
163 | * will call the handlers like in the next step. If the physical mapping has
|
---|
164 | * changed we will - some time in the future - perform a handler callback
|
---|
165 | * (optional) and update the physical -> virtual handler cache.
|
---|
166 | *
|
---|
167 | * 4. \#PF(,write) on a page in the range. This will cause the handler to
|
---|
168 | * be invoked.
|
---|
169 | *
|
---|
170 | * 5. The guest invalidates the page and changes the physical backing or
|
---|
171 | * unmaps it. This should cause the invalidation callback to be invoked
|
---|
172 | * (it might not yet be 100% perfect). Exactly what happens next... is
|
---|
173 | * this where we mess up and end up out of sync for a while?
|
---|
174 | *
|
---|
175 | * 6. The handler is deregistered by the client via PGMHandlerVirtualDeregister.
|
---|
176 | * We will then set all PGMPAGEs in the physical -> virtual handler cache for
|
---|
177 | * this handler to NONE and trigger a full PGM resync (basically the same
|
---|
178 | * as int step 1). Which means 2 is executed again.
|
---|
179 | *
|
---|
180 | *
|
---|
181 | * @subsubsection sub_sec_pgm_handler_virt_todo TODOs
|
---|
182 | *
|
---|
183 | * There is a bunch of things that needs to be done to make the virtual handlers
|
---|
184 | * work 100% correctly and work more efficiently.
|
---|
185 | *
|
---|
186 | * The first bit hasn't been implemented yet because it's going to slow the
|
---|
187 | * whole mess down even more, and besides it seems to be working reliably for
|
---|
188 | * our current uses. OTOH, some of the optimizations might end up more or less
|
---|
189 | * implementing the missing bits, so we'll see.
|
---|
190 | *
|
---|
191 | * On the optimization side, the first thing to do is to try avoid unnecessary
|
---|
192 | * cache flushing. Then try team up with the shadowing code to track changes
|
---|
193 | * in mappings by means of access to them (shadow in), updates to shadows pages,
|
---|
194 | * invlpg, and shadow PT discarding (perhaps).
|
---|
195 | *
|
---|
196 | * Some idea that have popped up for optimization for current and new features:
|
---|
197 | * - bitmap indicating where there are virtual handlers installed.
|
---|
198 | * (4KB => 2**20 pages, page 2**12 => covers 32-bit address space 1:1!)
|
---|
199 | * - Further optimize this by min/max (needs min/max avl getters).
|
---|
200 | * - Shadow page table entry bit (if any left)?

222 | * @subsection subsec_pgmPhys_AllocPage Allocating a page.
|
---|
223 | *
|
---|
224 | * Initially we map *all* guest memory to the (per VM) zero page, which
|
---|
225 | * means that none of the read functions will cause pages to be allocated.
|
---|
226 | *
|
---|
227 | * Exception, access bit in page tables that have been shared. This must
|
---|
228 | * be handled, but we must also make sure PGMGst*Modify doesn't make
|
---|
229 | * unnecessary modifications.
|
---|
230 | *
|
---|
231 | * Allocation points:
|
---|
232 | * - PGMPhysSimpleWriteGCPhys and PGMPhysWrite.
|
---|
233 | * - Replacing a zero page mapping at \#PF.
|
---|
234 | * - Replacing a shared page mapping at \#PF.
|
---|
235 | * - ROM registration (currently MMR3RomRegister).
|
---|
236 | * - VM restore (pgmR3Load).
|
---|
237 | *
|
---|
238 | * For the first three it would make sense to keep a few pages handy
|
---|
239 | * until we've reached the max memory commitment for the VM.
|
---|
240 | *
|
---|
241 | * For the ROM registration, we know exactly how many pages we need
|
---|
242 | * and will request these from ring-0. For restore, we will save
|
---|
243 | * the number of non-zero pages in the saved state and allocate
|
---|
244 | * them up front. This would allow the ring-0 component to refuse
|
---|
245 | * the request if the isn't sufficient memory available for VM use.
|
---|
246 | *
|
---|
247 | * Btw. for both ROM and restore allocations we won't be requiring
|
---|
248 | * zeroed pages as they are going to be filled instantly.
|
---|
249 | *
|
---|
250 | *
|
---|
251 | * @subsection subsec_pgmPhys_FreePage Freeing a page
|
---|
252 | *
|
---|
253 | * There are a few points where a page can be freed:
|
---|
254 | * - After being replaced by the zero page.
|
---|
255 | * - After being replaced by a shared page.
|
---|
256 | * - After being ballooned by the guest additions.
|
---|
257 | * - At reset.
|
---|
258 | * - At restore.
|
---|
259 | *
|
---|
260 | * When freeing one or more pages they will be returned to the ring-0
|
---|
261 | * component and replaced by the zero page.
|
---|
262 | *
|
---|
263 | * The reasoning for clearing out all the pages on reset is that it will
|
---|
264 | * return us to the exact same state as on power on, and may thereby help
|
---|
265 | * us reduce the memory load on the system. Further it might have a
|
---|
266 | * (temporary) positive influence on memory fragmentation (@see subsec_pgmPhys_Fragmentation).
|
---|
267 | *
|
---|
268 | * On restore, as mention under the allocation topic, pages should be
|
---|
269 | * freed / allocated depending on how many is actually required by the
|
---|
270 | * new VM state. The simplest approach is to do like on reset, and free
|
---|
271 | * all non-ROM pages and then allocate what we need.
|
---|
272 | *
|
---|
273 | * A measure to prevent some fragmentation, would be to let each allocation
|
---|
274 | * chunk have some affinity towards the VM having allocated the most pages
|
---|
275 | * from it. Also, try make sure to allocate from allocation chunks that
|
---|
276 | * are almost full. Admittedly, both these measures might work counter to
|
---|
277 | * our intentions and its probably not worth putting a lot of effort,
|
---|
278 | * cpu time or memory into this.
|
---|
279 | *
|
---|
280 | *
|
---|
281 | * @subsection subsec_pgmPhys_SharePage Sharing a page
|
---|
282 | *
|
---|
283 | * The basic idea is that there there will be a idle priority kernel
|
---|
284 | * thread walking the non-shared VM pages hashing them and looking for
|
---|
285 | * pages with the same checksum. If such pages are found, it will compare
|
---|
286 | * them byte-by-byte to see if they actually are identical. If found to be
|
---|
287 | * identical it will allocate a shared page, copy the content, check that
|
---|
288 | * the page didn't change while doing this, and finally request both the
|
---|
289 | * VMs to use the shared page instead. If the page is all zeros (special
|
---|
290 | * checksum and byte-by-byte check) it will request the VM that owns it
|
---|
291 | * to replace it with the zero page.
|
---|
292 | *
|
---|
293 | * To make this efficient, we will have to make sure not to try share a page
|
---|
294 | * that will change its contents soon. This part requires the most work.
|
---|
295 | * A simple idea would be to request the VM to write monitor the page for
|
---|
296 | * a while to make sure it isn't modified any time soon. Also, it may
|
---|
297 | * make sense to skip pages that are being write monitored since this
|
---|
298 | * information is readily available to the thread if it works on the
|
---|
299 | * per-VM guest memory structures (presently called PGMRAMRANGE).
|
---|
300 | *
|
---|
301 | *
|
---|
302 | * @subsection subsec_pgmPhys_Fragmentation Fragmentation Concerns and Counter Measures
|
---|
303 | *
|
---|
304 | * The pages are organized in allocation chunks in ring-0, this is a necessity
|
---|
305 | * if we wish to have an OS agnostic approach to this whole thing. (On Linux we
|
---|
306 | * could easily work on a page-by-page basis if we liked. Whether this is possible
|
---|
307 | * or efficient on NT I don't quite know.) Fragmentation within these chunks may
|
---|
308 | * become a problem as part of the idea here is that we wish to return memory to
|
---|
309 | * the host system.
|
---|
310 | *
|
---|
311 | * For instance, starting two VMs at the same time, they will both allocate the
|
---|
312 | * guest memory on-demand and if permitted their page allocations will be
|
---|
313 | * intermixed. Shut down one of the two VMs and it will be difficult to return
|
---|
314 | * any memory to the host system because the page allocation for the two VMs are
|
---|
315 | * mixed up in the same allocation chunks.
|
---|
316 | *
|
---|
317 | * To further complicate matters, when pages are freed because they have been
|
---|
318 | * ballooned or become shared/zero the whole idea is that the page is supposed
|
---|
319 | * to be reused by another VM or returned to the host system. This will cause
|
---|
320 | * allocation chunks to contain pages belonging to different VMs and prevent
|
---|
321 | * returning memory to the host when one of those VM shuts down.
|
---|
322 | *
|
---|
323 | * The only way to really deal with this problem is to move pages. This can
|
---|
324 | * either be done at VM shutdown and or by the idle priority worker thread
|
---|
325 | * that will be responsible for finding sharable/zero pages. The mechanisms
|
---|
326 | * involved for coercing a VM to move a page (or to do it for it) will be
|
---|
327 | * the same as when telling it to share/zero a page.
|
---|
328 | *
|
---|
329 | *
|
---|
330 | * @subsection subsec_pgmPhys_Tracking Tracking Structures And Their Cost
|
---|
331 | *
|
---|
332 | * There's a difficult balance between keeping the per-page tracking structures
|
---|
333 | * (global and guest page) easy to use and keeping them from eating too much
|
---|
334 | * memory. We have limited virtual memory resources available when operating in
|
---|
335 | * 32-bit kernel space (on 64-bit there'll it's quite a different story). The
|
---|
336 | * tracking structures will be attemted designed such that we can deal with up
|
---|
337 | * to 32GB of memory on a 32-bit system and essentially unlimited on 64-bit ones.

345 | *
|
---|
346 | * Fixed info is the physical address of the page (HCPhys) and the page id
|
---|
347 | * (described above). Theoretically we'll need 48(-12) bits for the HCPhys part.
|
---|
348 | * Today we've restricting ourselves to 40(-12) bits because this is the current
|
---|
349 | * restrictions of all AMD64 implementations (I think Barcelona will up this
|
---|
350 | * to 48(-12) bits, not that it really matters) and I needed the bits for
|
---|
351 | * tracking mappings of a page. 48-12 = 36. That leaves 28 bits, which means a
|
---|
352 | * decent range for the page id: 2^(28+12) = 1024TB.
|
---|
353 | *
|
---|
354 | * In additions to these, we'll have to keep maintaining the page flags as we
|
---|
355 | * currently do. Although it wouldn't harm to optimize these quite a bit, like
|
---|
356 | * for instance the ROM shouldn't depend on having a write handler installed
|
---|
357 | * in order for it to become read-only. A RO/RW bit should be considered so
|
---|
358 | * that the page syncing code doesn't have to mess about checking multiple
|
---|
359 | * flag combinations (ROM || RW handler || write monitored) in order to
|
---|
360 | * figure out how to setup a shadow PTE. But this of course, is second
|
---|
361 | * priority at present. Current this requires 12 bits, but could probably
|
---|
362 | * be optimized to ~8.
|
---|
363 | *
|
---|
364 | * Then there's the 24 bits used to track which shadow page tables are
|
---|
365 | * currently mapping a page for the purpose of speeding up physical
|
---|
366 | * access handlers, and thereby the page pool cache. More bit for this
|
---|
367 | * purpose wouldn't hurt IIRC.
|
---|
368 | *
|
---|
369 | * Then there is a new bit in which we need to record what kind of page
|
---|
370 | * this is, shared, zero, normal or write-monitored-normal. This'll
|
---|
371 | * require 2 bits. One bit might be needed for indicating whether a
|
---|
372 | * write monitored page has been written to. And yet another one or
|
---|
373 | * two for tracking migration status. 3-4 bits total then.
|
---|
374 | *
|
---|
375 | * Whatever is left will can be used to record the sharabilitiy of a
|
---|
376 | * page. The page checksum will not be stored in the per-VM table as
|
---|
377 | * the idle thread will not be permitted to do modifications to it.
|
---|
378 | * It will instead have to keep its own working set of potentially
|
---|
379 | * shareable pages and their check sums and stuff.
|
---|
380 | *
|
---|
381 | * For the present we'll keep the current packing of the
|
---|
382 | * PGMRAMRANGE::aHCPhys to keep the changes simple, only of course,
|
---|
383 | * we'll have to change it to a struct with a total of 128-bits at
|
---|
384 | * our disposal.
|
---|
385 | *
|
---|
386 | * The initial layout will be like this:
|
---|
387 | * @verbatim
|
---|
388 | RTHCPHYS HCPhys; The current stuff.
|
---|
389 | 63:40 Current shadow PT tracking stuff.

|
---|
402 | 63:48 High page id (12+).

414 | *
|
---|
415 | * Cost wise, this means we'll double the cost for guest memory. There isn't anyway
|
---|
416 | * around that I'm afraid. It means that the cost of dealing out 32GB of memory
|
---|
417 | * to one or more VMs is: (32GB >> PAGE_SHIFT) * 16 bytes, or 128MBs. Or another
|
---|
418 | * example, the VM heap cost when assigning 1GB to a VM will be: 4MB.
|
---|
419 | *
|
---|
420 | * A couple of cost examples for the total cost per-VM + kernel.
|
---|
421 | * 32-bit Windows and 32-bit linux:
|
---|
422 | * 1GB guest ram, 256K pages: 4MB + 2MB(+) = 6MB
|
---|
423 | * 4GB guest ram, 1M pages: 16MB + 8MB(+) = 24MB
|
---|
424 | * 32GB guest ram, 8M pages: 128MB + 64MB(+) = 192MB
|
---|
425 | * 64-bit Windows and 64-bit linux:
|
---|
426 | * 1GB guest ram, 256K pages: 4MB + 3MB(+) = 7MB
|
---|
427 | * 4GB guest ram, 1M pages: 16MB + 12MB(+) = 28MB
|
---|
428 | * 32GB guest ram, 8M pages: 128MB + 96MB(+) = 224MB
|
---|
429 | *
|
---|
430 | * UPDATE - 2007-09-27:
|
---|
431 | * Will need a ballooned flag/state too because we cannot
|
---|
432 | * trust the guest 100% and reporting the same page as ballooned more
|
---|
433 | * than once will put the GMM off balance.

|
---|
436 | * @subsection subsec_pgmPhys_Serializing Serializing Access
|
---|
437 | *
|
---|
438 | * Initially, we'll try a simple scheme:
|
---|
439 | *
|
---|
440 | * - The per-VM RAM tracking structures (PGMRAMRANGE) is only modified
|
---|
441 | * by the EMT thread of that VM while in the pgm critsect.
|
---|
442 | * - Other threads in the VM process that needs to make reliable use of
|
---|
443 | * the per-VM RAM tracking structures will enter the critsect.
|
---|
444 | * - No process external thread or kernel thread will ever try enter
|
---|
445 | * the pgm critical section, as that just won't work.
|
---|
446 | * - The idle thread (and similar threads) doesn't not need 100% reliable
|
---|
447 | * data when performing it tasks as the EMT thread will be the one to
|
---|
448 | * do the actual changes later anyway. So, as long as it only accesses
|
---|
449 | * the main ram range, it can do so by somehow preventing the VM from
|
---|
450 | * being destroyed while it works on it...
|
---|
451 | *
|
---|
452 | * - The over-commitment management, including the allocating/freeing
|
---|
453 | * chunks, is serialized by a ring-0 mutex lock (a fast one since the
|
---|
454 | * more mundane mutex implementation is broken on Linux).
|
---|
455 | * - A separeate mutex is protecting the set of allocation chunks so
|
---|
456 | * that pages can be shared or/and freed up while some other VM is
|
---|
457 | * allocating more chunks. This mutex can be take from under the other
|
---|
458 | * one, but not the otherway around.
|
---|
459 | *
|
---|
460 | *
|
---|
461 | * @subsection subsec_pgmPhys_Request VM Request interface
|
---|
462 | *
|
---|
463 | * When in ring-0 it will become necessary to send requests to a VM so it can
|
---|
464 | * for instance move a page while defragmenting during VM destroy. The idle
|
---|
465 | * thread will make use of this interface to request VMs to setup shared
|
---|
466 | * pages and to perform write monitoring of pages.
|
---|
467 | *
|
---|
468 | * I would propose an interface similar to the current VMReq interface, similar
|
---|
469 | * in that it doesn't require locking and that the one sending the request may
|
---|
470 | * wait for completion if it wishes to. This shouldn't be very difficult to
|
---|
471 | * realize.
|
---|
472 | *
|
---|
473 | * The requests themselves are also pretty simple. They are basically:
|
---|
474 | * -# Check that some precondition is still true.
|
---|
475 | * -# Do the update.
|
---|
476 | * -# Update all shadow page tables involved with the page.
|
---|
477 | *
|
---|
478 | * The 3rd step is identical to what we're already doing when updating a
|
---|
479 | * physical handler, see pgmHandlerPhysicalSetRamFlagsAndFlushShadowPTs.

|
---|
484 | *
|
---|
485 | * In order to be able to map in and out memory and to be able to support
|
---|
486 | * guest with more RAM than we've got virtual address space, we'll employing
|
---|
487 | * a mapping cache. There is already a tiny one for GC (see PGMGCDynMapGCPageEx)
|
---|
488 | * and we'll create a similar one for ring-0 unless we decide to setup a dedicate
|
---|
489 | * memory context for the HWACCM execution.
|
---|
490 | *
|
---|
491 | *
|
---|
492 | * @subsection subsec_pgmPhys_MappingCaches_R3 Ring-3
|
---|
493 | *
|
---|
494 | * We've considered implementing the ring-3 mapping cache page based but found
|
---|
495 | * that this was bother some when one had to take into account TLBs+SMP and
|
---|
496 | * portability (missing the necessary APIs on several platforms). There were
|
---|
497 | * also some performance concerns with this approach which hadn't quite been
|
---|
498 | * worked out.
|
---|
499 | *
|
---|
500 | * Instead, we'll be mapping allocation chunks into the VM process. This simplifies
|
---|
501 | * matters greatly quite a bit since we don't need to invent any new ring-0 stuff,
|
---|
502 | * only some minor RTR0MEMOBJ mapping stuff. The main concern here is that mapping
|
---|
503 | * compared to the previous idea is that mapping or unmapping a 1MB chunk is more
|
---|
504 | * costly than a single page, although how much more costly is uncertain. We'll
|
---|
505 | * try address this by using a very big cache, preferably bigger than the actual
|
---|
506 | * VM RAM size if possible. The current VM RAM sizes should give some idea for
|
---|
507 | * 32-bit boxes, while on 64-bit we can probably get away with employing an
|
---|
508 | * unlimited cache.
|
---|
509 | *
|
---|
510 | * The cache have to parts, as already indicated, the ring-3 side and the
|
---|
511 | * ring-0 side.
|
---|
512 | *
|
---|
513 | * The ring-0 will be tied to the page allocator since it will operate on the
|
---|
514 | * memory objects it contains. It will therefore require the first ring-0 mutex
|
---|
515 | * discussed in @ref subsec_pgmPhys_Serializing. We
|
---|
516 | * some double house keeping wrt to who has mapped what I think, since both
|
---|
517 | * VMMR0.r0 and RTR0MemObj will keep track of mapping relataions
|
---|
518 | *
|
---|
519 | * The ring-3 part will be protected by the pgm critsect. For simplicity, we'll
|
---|
520 | * require anyone that desires to do changes to the mapping cache to do that
|
---|
521 | * from within this critsect. Alternatively, we could employ a separate critsect
|
---|
522 | * for serializing changes to the mapping cache as this would reduce potential
|
---|
523 | * contention with other threads accessing mappings unrelated to the changes
|
---|
524 | * that are in process. We can see about this later, contention will show
|
---|
525 | * up in the statistics anyway, so it'll be simple to tell.
|
---|
526 | *
|
---|
527 | * The organization of the ring-3 part will be very much like how the allocation
|
---|
528 | * chunks are organized in ring-0, that is in an AVL tree by chunk id. To avoid
|
---|
529 | * having to walk the tree all the time, we'll have a couple of lookaside entries
|
---|
530 | * like in we do for I/O ports and MMIO in IOM.
|
---|
531 | *
|
---|
532 | * The simplified flow of a PGMPhysRead/Write function:
|
---|
533 | * -# Enter the PGM critsect.
|
---|
534 | * -# Lookup GCPhys in the ram ranges and get the Page ID.
|
---|
535 | * -# Calc the Allocation Chunk ID from the Page ID.
|
---|
536 | * -# Check the lookaside entries and then the AVL tree for the Chunk ID.
|
---|
537 | * If not found in cache:
|
---|
538 | * -# Call ring-0 and request it to be mapped and supply
|
---|
539 | * a chunk to be unmapped if the cache is maxed out already.
|
---|
540 | * -# Insert the new mapping into the AVL tree (id + R3 address).
|
---|
541 | * -# Update the relevant lookaside entry and return the mapping address.
|
---|
542 | * -# Do the read/write according to monitoring flags and everything.
|
---|
543 | * -# Leave the critsect.
|
---|

|
---|
546 | * @section sec_pgmPhys_Fallback Fallback
|
---|
547 | *
|
---|
548 | * Current all the "second tier" hosts will not support the RTR0MemObjAllocPhysNC
|
---|
549 | * API and thus require a fallback.
|
---|
550 | *
|
---|
551 | * So, when RTR0MemObjAllocPhysNC returns VERR_NOT_SUPPORTED the page allocator
|
---|
552 | * will return to the ring-3 caller (and later ring-0) and asking it to seed
|
---|
553 | * the page allocator with some fresh pages (VERR_GMM_SEED_ME). Ring-3 will
|
---|
554 | * then perform an SUPPageAlloc(cbChunk >> PAGE_SHIFT) call and make a
|
---|
555 | * "SeededAllocPages" call to ring-0.
|
---|
556 | *
|
---|
557 | * The first time ring-0 sees the VERR_NOT_SUPPORTED failure it will disable
|
---|
558 | * all page sharing (zero page detection will continue). It will also force
|
---|
559 | * all allocations to come from the VM which seeded the page. Both these
|
---|
560 | * measures are taken to make sure that there will never be any need for
|
---|
561 | * mapping anything into ring-3 - everything will be mapped already.
|
---|
562 | *
|
---|
563 | * Whether we'll continue to use the current MM locked memory management
|
---|
564 | * for this I don't quite know (I'd prefer not to and just ditch that all
|
---|
565 | * togther), we'll see what's simplest to do.
