44 | * - Making sure aliases of the memory behind the mapping don't violate | ||

48 | * - Provide exclusion between various callers - including callers that | ||

50 | * - Restore default attributes when a page is freed | ||
51 | * - Guarantee that mappings other than the requested one are | ||

53 | * the CPU you have. Do not depend on any effects on other mappings, | ||
54 | * CPUs other than the one you have may have more relaxed rules. | ||

24 | * NOTES about DMA transfers: | ||
25 | * | ||
26 | * controller 1: channels 0-3, byte operations, ports 00-1F | ||
27 | * controller 2: channels 4-7, word operations, ports C0-DF | ||
28 | * | ||
29 | * - ALL registers are 8 bits only, regardless of transfer size | ||
30 | * - channel 4 is not used - cascades 1 into 2. | ||
31 | * - channels 0-3 are byte - addresses/counts are for physical bytes | ||
32 | * - channels 5-7 are word - addresses/counts are for physical words | ||
33 | * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries | ||
34 | * - transfer count loaded to registers is 1 less than actual count | ||
35 | * - controller 2 offsets are all even (2x offsets for controller 1) | ||
36 | * - page registers for 5-7 don't use data bit 0, represent 128K pages | ||
37 | * - page registers for 0-3 use bit 0, represent 64K pages | ||
38 | * | ||
39 | * DMA transfers are limited to the lower 16MB of _physical_ memory. | ||
40 | * Note that addresses loaded into registers must be _physical_ addresses, | ||
41 | * not logical addresses (which may differ if paging is active). | ||
42 | * | ||
43 | * Address mapping for channels 0-3: | ||
44 | * | ||
45 | * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses) | ||
46 | * | ... | | ... | | ... | | ||
47 | * | ... | | ... | | ... | | ||
48 | * | ... | | ... | | ... | | ||
49 | * P7 ... P0 A7 ... A0 A7 ... A0 | ||
50 | * | Page | Addr MSB | Addr LSB | (DMA registers) | ||
51 | * | ||
52 | * Address mapping for channels 5-7: | ||
53 | * | ||
54 | * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses) | ||
55 | * | ... | \ \ ... \ \ \ ... \ \ | ||
56 | * | ... | \ \ ... \ \ \ ... \ (not used) | ||
57 | * | ... | \ \ ... \ \ \ ... \ | ||
58 | * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0 | ||
59 | * | Page | Addr MSB | Addr LSB | (DMA registers) | ||
60 | * | ||
61 | * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses | ||
62 | * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at | ||
63 | * the hardware level, so odd-byte transfers aren't possible). | ||
64 | * | ||
65 | * Transfer count (_not # bytes_) is limited to 64K, represented as actual | ||
66 | * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more, | ||
67 | * and up to 128K bytes may be transferred on channels 5-7 in one operation. | ||

17 | * x86_emulate_ops: | ||

19 | * These operations represent the instruction emulator's interface to memory. | ||
20 | * There are two categories of operation: those that act on ordinary memory | ||
21 | * regions (*_std), and those that act on memory regions known to require | ||
22 | * special treatment or emulation (*_emulated). | ||
23 | * | ||
24 | * The emulator assumes that an instruction accesses only one 'emulated memory' | ||
25 | * location, that this location is the given linear faulting address (cr2), and | ||
26 | * that this is one of the instruction's data operands. Instruction fetches and | ||
27 | * stack operations are assumed never to access emulated memory. The emulator | ||
28 | * automatically deduces which operand of a string-move operation is accessing | ||
29 | * emulated memory, and assumes that the other operand accesses normal memory. | ||
30 | * | ||
31 | * NOTES: | ||
32 | * 1. The emulator isn't very smart about emulated vs. standard memory. | ||
33 | * 'Emulated memory' access addresses should be checked for sanity. | ||
34 | * 'Normal memory' accesses may fault, and the caller must arrange to | ||
35 | * detect and handle reentrancy into the emulator via recursive faults. | ||
36 | * Accesses may be unaligned and may cross page boundaries. | ||
37 | * 2. If the access fails (cannot emulate, or a standard access faults) then | ||
38 | * it is up to the memop to propagate the fault to the guest VM via | ||
39 | * some out-of-band mechanism, unknown to the emulator. The memop signals | ||
40 | * failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will | ||
41 | * then immediately bail. | ||
42 | * 3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only | ||
43 | * cmpxchg8b_emulated need support 8-byte accesses. | ||
44 | * 4. The emulator cannot handle 64-bit mode emulation on an x86/32 system. | ||

422 | * Normally, a call to a pv_op function is a simple indirect call: | ||
423 | * (pv_op_struct.operations)(args...). | ||
424 | * | ||
425 | * Unfortunately, this is a relatively slow operation for modern CPUs, | ||
426 | * because it cannot necessarily determine what the destination | ||
427 | * address is. In this case, the address is a runtime constant, so at | ||
428 | * the very least we can patch the call to e a simple direct call, or | ||
429 | * ideally, patch an inline implementation into the callsite. (Direct | ||
430 | * calls are essentially free, because the call and return addresses | ||
431 | * are completely predictable.) | ||
432 | * | ||
433 | * For i386, these macros rely on the standard gcc "regparm(3)" calling | ||
434 | * convention, in which the first three arguments are placed in %eax, | ||
435 | * %edx, %ecx (in that order), and the remaining arguments are placed | ||
436 | * on the stack. All caller-save registers (eax,edx,ecx) are expected | ||
437 | * to be modified (either clobbered or used for return values). | ||
438 | * X86_64, on the other hand, already specifies a register-based calling | ||
439 | * conventions, returning at %rax, with parameteres going on %rdi, %rsi, | ||
440 | * %rdx, and %rcx. Note that for this reason, x86_64 does not need any | ||
441 | * special handling for dealing with 4 arguments, unlike i386. | ||
442 | * However, x86_64 also have to clobber all caller saved registers, which | ||
443 | * unfortunately, are quite a bit (r8 - r11) | ||
444 | * | ||
445 | * The call instruction itself is marked by placing its start address | ||
446 | * and size into the .parainstructions section, so that | ||
447 | * apply_paravirt() in arch/i386/kernel/alternative.c can do the | ||
448 | * appropriate patching under the control of the backend pv_init_ops | ||
449 | * implementation. | ||
450 | * | ||
451 | * Unfortunately there's no way to get gcc to generate the args setup | ||
452 | * for the call, and then allow the call itself to be generated by an | ||
453 | * inline asm. Because of this, we must do the complete arg setup and | ||
454 | * return value handling from within these macros. This is fairly | ||
455 | * cumbersome. | ||
456 | * | ||
457 | * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments. | ||
458 | * It could be extended to more arguments, but there would be little | ||
459 | * to be gained from that. For each number of arguments, there are | ||
460 | * the two VCALL and CALL variants for void and non-void functions. | ||
461 | * | ||
462 | * When there is a return value, the invoker of the macro must specify | ||
463 | * the return type. The macro then uses sizeof() on that type to | ||
464 | * determine whether its a 32 or 64 bit value, and places the return | ||
465 | * in the right register(s) (just %eax for 32-bit, and %edx:%eax for | ||
466 | * 64-bit). For x86_64 machines, it just returns at %rax regardless of | ||
467 | * the return value size. | ||
468 | * | ||
469 | * 64-bit arguments are passed as a pair of adjacent 32-bit arguments | ||
470 | * i386 also passes 64-bit arguments as a pair of adjacent 32-bit arguments | ||
471 | * in low,high order | ||
472 | * | ||
473 | * Small structures are passed and returned in registers. The macro | ||
474 | * calling convention can't directly deal with this, so the wrapper | ||
475 | * functions must do this. | ||
476 | * | ||
477 | * These PVOP_* macros are only defined within this header. This | ||
478 | * means that all uses must be wrapped in inline functions. This also | ||
479 | * makes sure the incoming and outgoing types are always correct. | ||

1 | /* rwsem.h: R/W semaphores implemented using XADD/CMPXCHG for i486+ | ||
2 | * | ||
3 | * Written by David Howells (dhowells@redhat.com). | ||
4 | * | ||
5 | * Derived from asm-x86/semaphore.h | ||
6 | * | ||
7 | * | ||
8 | * The MSW of the count is the negated number of active writers and waiting | ||
9 | * lockers, and the LSW is the total number of active locks | ||
10 | * | ||
11 | * The lock count is initialized to 0 (no active and no waiting lockers). | ||
12 | * | ||
13 | * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an | ||
14 | * uncontended lock. This can be determined because XADD returns the old value. | ||
15 | * Readers increment by 1 and see a positive value when uncontended, negative | ||
16 | * if there are writers (and maybe) readers waiting (in which case it goes to | ||
17 | * sleep). | ||
18 | * | ||
19 | * The value of WAITING_BIAS supports up to 32766 waiting processes. This can | ||
20 | * be extended to 65534 by manually checking the whole MSW rather than relying | ||
21 | * on the S flag. | ||
22 | * | ||
23 | * The value of ACTIVE_BIAS supports up to 65535 active processes. | ||
24 | * | ||
25 | * This should be totally fair - if anything is waiting, a process that wants a | ||
26 | * lock will go to the back of the queue. When the currently active lock is | ||
27 | * released, if there's a writer at the front of the queue, then that and only | ||
28 | * that will be woken up; if there's a bunch of consequtive readers at the | ||
29 | * front, then they'll all be woken up, but no other readers will be. | ||

339 | * | ||
340 | * No data-dependent reads from memory-like regions are ever reordered | ||
341 | * over this barrier. All reads preceding this primitive are guaranteed | ||
342 | * to access memory (but not necessarily other CPUs' caches) before any | ||
343 | * reads following this primitive that depend on the data return by | ||
344 | * any of the preceding reads. This primitive is much lighter weight than | ||
345 | * rmb() on most CPUs, and is never heavier weight than is | ||
346 | * rmb(). | ||
347 | * | ||
348 | * These ordering constraints are respected by both the local CPU | ||
349 | * and the compiler. | ||
350 | * | ||
351 | * Ordering is not guaranteed by anything other than these primitives, | ||
352 | * not even by data dependencies. See the documentation for | ||
353 | * memory_barrier() for examples and URLs to more information. | ||
354 | * | ||
355 | * For example, the following code would force ordering (the initial | ||
356 | * value of "a" is zero, "b" is one, and "p" is "&a"): | ||
357 | * | ||
358 | * <programlisting> | ||

364 | * read_barrier_depends(); | ||
365 | * d = *q; | ||
366 | * </programlisting> | ||
367 | * | ||
368 | * because the read of "*q" depends on the read of "p" and these | ||
369 | * two reads are separated by a read_barrier_depends(). However, | ||
370 | * the following code, with the same initial values for "a" and "b": | ||
371 | * | ||
372 | * <programlisting> | ||
373 | * CPU 0 CPU 1 | ||
374 | * | ||
375 | * a = 2; | ||

377 | * b = 3; y = b; | ||
378 | * read_barrier_depends(); | ||
379 | * x = a; | ||
380 | * </programlisting> | ||
381 | * | ||
382 | * does not enforce ordering, since there is no data dependency between | ||
383 | * the read of "a" and the read of "b". Therefore, on some CPUs, such | ||
384 | * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb() | ||

20 | current->brk to pick up all of the user variables, plus any memory | ||
21 | that may have been malloced. No attempt is made to determine if a page | ||
22 | is demand-zero or if a page is totally unused, we just cover the entire | ||
23 | range. All of the addresses are rounded in such a way that an integral | ||
24 | number of pages is written. | ||
25 | STACK: We need the stack information in order to get a meaningful | ||
26 | backtrace. We need to write the data from (esp) to | ||
27 | current->start_stack, so we round each of these off in order to be able | ||

22 | * to an MMR. | ||
23 | * Thus there are 64 unique 512-byte sets of SB descriptors - one set for | ||
24 | * each 6-bit index value. These descriptor sets are mapped in sequence | ||
25 | * starting with set 0 located at the address specified in the | ||
26 | * BAU_SB_DESCRIPTOR_BASE register, set 1 is located at BASE + 512, | ||
27 | * set 2 is at BASE + 2*512, set 3 at BASE + 3*512, and so on. | ||
28 | * | ||
29 | * We will use 31 sets, one for sending BAU messages from each of the 32 | ||
30 | * cpu's on the node. | ||
31 | * | ||
32 | * TLB shootdown will use the first of the 8 descriptors of each set. | ||

21 | * Addressing Terminology | ||
22 | * | ||
23 | * M - The low M bits of a physical address represent the offset | ||
24 | * into the blade local memory. RAM memory on a blade is physically | ||
25 | * contiguous (although various IO spaces may punch holes in | ||
26 | * it).. | ||
27 | * | ||
28 | * N - Number of bits in the node portion of a socket physical | ||
29 | * address. | ||
30 | * | ||
31 | * NASID - network ID of a router, Mbrick or Cbrick. Nasid values of | ||
32 | * routers always have low bit of 1, C/MBricks have low bit | ||
33 | * equal to 0. Most addressing macros that target UV hub chips | ||
34 | * right shift the NASID by 1 to exclude the always-zero bit. | ||
35 | * NASIDs contain up to 15 bits. | ||
36 | * | ||
37 | * GNODE - NASID right shifted by 1 bit. Most mmrs contain gnodes instead | ||
38 | * of nasids. | ||
39 | * | ||
40 | * PNODE - the low N bits of the GNODE. The PNODE is the most useful variant | ||
41 | * of the nasid for socket usage. | ||
42 | * | ||

58 | * | ||
59 | * M - number of node offset bits (35 .. 40) | ||
60 | * N - number of PNODE bits (0 .. 10) | ||
61 | * | ||
62 | * Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64). | ||
63 | * The actual values are configuration dependent and are set at | ||

43 | /* | ||
44 | * The hypercall asms have to meet several constraints: | ||
45 | * - Work on 32- and 64-bit. | ||
46 | * The two architectures put their arguments in different sets of | ||
47 | * registers. | ||
48 | * | ||
49 | * - Work around asm syntax quirks | ||
50 | * It isn't possible to specify one of the rNN registers in a | ||
51 | * constraint, so we use explicit register variables to get the | ||
52 | * args into the right place. | ||
53 | * | ||
54 | * - Mark all registers as potentially clobbered | ||
55 | * Even unused parameters can be clobbered by the hypervisor, so we | ||
56 | * need to make sure gcc knows it. | ||
57 | * | ||
58 | * - Avoid compiler bugs. | ||
59 | * This is the tricky part. Because x86_32 has such a constrained | ||
60 | * register set, gcc versions below 4.3 have trouble generating | ||
61 | * code when all the arg registers and memory are trashed by the | ||
62 | * asm. There are syntactically simpler ways of achieving the | ||
63 | * semantics below, but they cause the compiler to crash. | ||
64 | * | ||
65 | * The only combination I found which works is: | ||
66 | * - assign the __argX variables first | ||
67 | * - list all actually used parameters as "+r" (__argX) | ||
68 | * - clobber the rest | ||
69 | * | ||
70 | * The result certainly isn't pretty, and it really shows up cpp's | ||
71 | * weakness as as macro language. Sorry. (But let's just give thanks | ||
72 | * there aren't more than 5 arguments...) | ||
