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