15 Binder is used in Android for both communication between processes,
16 and remote method invocation.
17
18 This means one Android process can call a method/routine in another
19 Android process, using Binder to identify, invoke and pass arguments
20 between said processes.

Robert Love11980c22011-12-20 16:49:48 -0800[diff] [blame]27 The ashmem subsystem is a new shared memory allocator, similar to
28 POSIX SHM but with different behavior and sporting a simpler
29 file-based API.
30
Cruz Julian Bishopd7f97292012-12-22 09:00:46 +1000[diff] [blame]31 It is, in theory, a good memory allocator for low-memory devices,
32 because it can discard shared memory units when under memory pressure.

38 This adds support for system-wide logging using four log buffers.
39
40 These are:
41
42 1: main
43 2: events
44 3: radio
45 4: system
46
47 Log reading and writing is performed via normal Linux reads and
48 optimized writes. This optimization avoids logging having too
49 much overhead in the system.
