13/*
14 * Hardware-wise, we have a two level page table structure, where the first
15 * level has 4096 entries, and the second level has 256 entries. Each entry
16 * is one 32-bit word. Most of the bits in the second level entry are used
17 * by hardware, and there aren't any "accessed" and "dirty" bits.
18 *
19 * Linux on the other hand has a three level page table structure, which can
20 * be wrapped to fit a two level page table structure easily - using the PGD
21 * and PTE only. However, Linux also expects one "PTE" table per page, and
22 * at least a "dirty" bit.
23 *
24 * Therefore, we tweak the implementation slightly - we tell Linux that we
25 * have 2048 entries in the first level, each of which is 8 bytes (iow, two
26 * hardware pointers to the second level.) The second level contains two
27 * hardware PTE tables arranged contiguously, preceded by Linux versions
28 * which contain the state information Linux needs. We, therefore, end up
29 * with 512 entries in the "PTE" level.
30 *
31 * This leads to the page tables having the following layout:
32 *
33 * pgd pte
34 * | |
35 * +--------+
36 * | | +------------+ +0
37 * +- - - - + | Linux pt 0 |
38 * | | +------------+ +1024
39 * +--------+ +0 | Linux pt 1 |
40 * | |-----> +------------+ +2048
41 * +- - - - + +4 | h/w pt 0 |
42 * | |-----> +------------+ +3072
43 * +--------+ +8 | h/w pt 1 |
44 * | | +------------+ +4096
45 *
46 * See L_PTE_xxx below for definitions of bits in the "Linux pt", and
47 * PTE_xxx for definitions of bits appearing in the "h/w pt".
48 *
49 * PMD_xxx definitions refer to bits in the first level page table.
50 *
51 * The "dirty" bit is emulated by only granting hardware write permission
52 * iff the page is marked "writable" and "dirty" in the Linux PTE. This
53 * means that a write to a clean page will cause a permission fault, and
54 * the Linux MM layer will mark the page dirty via handle_pte_fault().
55 * For the hardware to notice the permission change, the TLB entry must
56 * be flushed, and ptep_set_access_flags() does that for us.
57 *
58 * The "accessed" or "young" bit is emulated by a similar method; we only
59 * allow accesses to the page if the "young" bit is set. Accesses to the
60 * page will cause a fault, and handle_pte_fault() will set the young bit
61 * for us as long as the page is marked present in the corresponding Linux
62 * PTE entry. Again, ptep_set_access_flags() will ensure that the TLB is
63 * up to date.
64 *
65 * However, when the "young" bit is cleared, we deny access to the page
66 * by clearing the hardware PTE. Currently Linux does not flush the TLB
67 * for us in this case, which means the TLB will retain the transation
68 * until either the TLB entry is evicted under pressure, or a context
69 * switch which changes the user space mapping occurs.

56 * have 2048 entries in the first level, each of which is 8 bytes (iow, two
57 * hardware pointers to the second level.) The second level contains two
58 * hardware PTE tables arranged contiguously, preceded by Linux versions
59 * which contain the state information Linux needs. We, therefore, end up
60 * with 512 entries in the "PTE" level.
61 *
62 * This leads to the page tables having the following layout:
63 *
64 * pgd pte
65 * | |
66 * +--------+
67 * | | +------------+ +0
68 * +- - - - + | Linux pt 0 |
69 * | | +------------+ +1024
70 * +--------+ +0 | Linux pt 1 |
71 * | |-----> +------------+ +2048
72 * +- - - - + +4 | h/w pt 0 |
73 * | |-----> +------------+ +3072
74 * +--------+ +8 | h/w pt 1 |
75 * | | +------------+ +4096
76 *
77 * See L_PTE_xxx below for definitions of bits in the "Linux pt", and
78 * PTE_xxx for definitions of bits appearing in the "h/w pt".
79 *
80 * PMD_xxx definitions refer to bits in the first level page table.
81 *
82 * The "dirty" bit is emulated by only granting hardware write permission
83 * iff the page is marked "writable" and "dirty" in the Linux PTE. This
84 * means that a write to a clean page will cause a permission fault, and
85 * the Linux MM layer will mark the page dirty via handle_pte_fault().
86 * For the hardware to notice the permission change, the TLB entry must
87 * be flushed, and ptep_set_access_flags() does that for us.
88 *
89 * The "accessed" or "young" bit is emulated by a similar method; we only
90 * allow accesses to the page if the "young" bit is set. Accesses to the
91 * page will cause a fault, and handle_pte_fault() will set the young bit
92 * for us as long as the page is marked present in the corresponding Linux
93 * PTE entry. Again, ptep_set_access_flags() will ensure that the TLB is
94 * up to date.
95 *
96 * However, when the "young" bit is cleared, we deny access to the page
97 * by clearing the hardware PTE. Currently Linux does not flush the TLB
98 * for us in this case, which means the TLB will retain the transation
99 * until either the TLB entry is evicted under pressure, or a context
100 * switch which changes the user space mapping occurs.
