21 | /* This module implements a sort of half target that sits between the | |
8d027a04 MK |
22 | machine-independent parts of GDB and the /proc interface (procfs.c) |
23 | to provide access to the Solaris user-mode thread implementation. | |
24 | ||
25 | Solaris threads are true user-mode threads, which are invoked via | |
26 | the thr_* and pthread_* (native and POSIX respectivly) interfaces. | |
27 | These are mostly implemented in user-space, with all thread context | |
28 | kept in various structures that live in the user's heap. These | |
29 | should not be confused with lightweight processes (LWPs), which are | |
30 | implemented by the kernel, and scheduled without explicit | |
31 | intervention by the process. | |
32 | ||
33 | Just to confuse things a little, Solaris threads (both native and | |
34 | POSIX) are actually implemented using LWPs. In general, there are | |
35 | going to be more threads than LWPs. There is no fixed | |
36 | correspondence between a thread and an LWP. When a thread wants to | |
37 | run, it gets scheduled onto the first available LWP and can | |
38 | therefore migrate from one LWP to another as time goes on. A | |
c906108c SS |
39 | sleeping thread may not be associated with an LWP at all! |
40 | ||
8d027a04 MK |
41 | To make it possible to mess with threads, Sun provides a library |
42 | called libthread_db.so.1 (not to be confused with | |
43 | libthread_db.so.0, which doesn't have a published interface). This | |
44 | interface has an upper part, which it provides, and a lower part | |
45 | which we provide. The upper part consists of the td_* routines, | |
46 | which allow us to find all the threads, query their state, etc... | |
47 | The lower part consists of all of the ps_*, which are used by the | |
48 | td_* routines to read/write memory, manipulate LWPs, lookup | |
49 | symbols, etc... The ps_* routines actually do most of their work | |
50 | by calling functions in procfs.c. */ | |
