19 | * The lock count is initialized to 0 (no active and no waiting lockers). | ||
20 | * | ||
21 | * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an | ||
22 | * uncontended lock. This can be determined because XADD returns the old value. | ||
23 | * Readers increment by 1 and see a positive value when uncontended, negative | ||

28 | * be extended to 65534 by manually checking the whole MSW rather than relying | ||
29 | * on the S flag. | ||
30 | * | ||
31 | * The value of ACTIVE_BIAS supports up to 65535 active processes. | ||
32 | * | ||
33 | * This should be totally fair - if anything is waiting, a process that wants a | ||
34 | * lock will go to the back of the queue. When the currently active lock is | ||
35 | * released, if there's a writer at the front of the queue, then that and only | ||
36 | * that will be woken up; if there's a bunch of consequtive readers at the | ||
37 | * front, then they'll all be woken up, but no other readers will be. | ||

8 | * "A valid table entry must not be changed while it is attached | ||
9 | * to any CPU and may be used for translation by that CPU except to | ||
10 | * (1) invalidate the entry by using INVALIDATE PAGE TABLE ENTRY, | ||

14 | /* Core file format: The core file is written in such a way that gdb | ||
15 | can understand it and provide useful information to the user (under | ||
16 | linux we use the 'trad-core' bfd). There are quite a number of | ||
17 | obstacles to being able to view the contents of the floating point | ||
18 | registers, and until these are solved you will not be able to view the | ||
19 | contents of them. Actually, you can read in the core file and look at | ||
20 | the contents of the user struct to find out what the floating point | ||
21 | registers contain. | ||
22 | The actual file contents are as follows: | ||
23 | UPAGE: 1 page consisting of a user struct that tells gdb what is present | ||
24 | in the file. Directly after this is a copy of the task_struct, which | ||
25 | is currently not used by gdb, but it may come in useful at some point. | ||
26 | All of the registers are stored as part of the upage. The upage should | ||
27 | always be only one page. | ||
28 | DATA: The data area is stored. We use current->end_text to | ||
29 | current->brk to pick up all of the user variables, plus any memory | ||
30 | that may have been malloced. No attempt is made to determine if a page | ||
31 | is demand-zero or if a page is totally unused, we just cover the entire | ||
32 | range. All of the addresses are rounded in such a way that an integral | ||
33 | number of pages is written. | ||
34 | STACK: We need the stack information in order to get a meaningful | ||
35 | backtrace. We need to write the data from (esp) to | ||
36 | current->start_stack, so we round each of these off in order to be able | ||
37 | to write an integer number of pages. | ||
38 | The minimum core file size is 3 pages, or 12288 bytes. | ||
