+# ADB Internals
+
+If you are new to adb source code, you should start by reading [OVERVIEW.TXT](OVERVIEW.TXT) which describes the three components of adb pipeline.
+
+This document is here to boost what can be achieved within a "window of naive interest". You will not find function or class documentation here but rather the "big picture" which should allow you to build a mental map to help navigate the code.
+
+## Three components of adb pipeline
+
+As outlined in the overview, this codebase generates three components (Client, Server (a.k.a Host), and Daemon (a.k.a adbd)). The central part is the Server which runs on the Host computer. On one side the Server exposes a "Smart Socket" to Clients such as adb or DDMLIB. On the other side, the Server continuously monitors for connecting Daemons (as USB devices or TCP emulator). Communication with a device is done with a Transport.
+
+```
++----------+              +------------------------+
+|   ADB    +----------+   |      ADB SERVER        |                   +----------+

+                                                                       +----------+
+```
+
+The Client and the Server are contained in the same executable and both run on the Host machine. Code sections specific to the Host is enclosed within `ADB_HOST` guard. adbd runs on the Android Device. Daemon specific code is enclosed in `!ADB_HOST` but also sometimes with-in `__ANDROID__` guard.
+
+
+## "SMART SOCKET" and TRANSPORT
+
+A smart socket is a simple TCP socket with a smart protocol built on top of it. This is what Clients connect onto from the Host side. The Client must always initiate communication via a human readable request but the response format varies. The smart protocol is documented in [SERVICES.TXT](SERVICES.TXT).
+
+On the other side, the Server communicate with a device via a Transport. adb initially targeted devices connecting over USB, which is restricted to a fixed number of data streams. Therefore, adb multiplexes multiple byte streams over a single pipe via Transport. When devices connecting over other mechanisms (e.g. emulators over TCP) were introduced, the existing transport protocol was maintained.
+
+## THREADING MODEL and FDEVENT system
+
+At the heart of both the Server and Daemon is a main thread running an fdevent loop, which is an platform-independent abstraction over poll/epoll/WSAPoll monitoring file descriptors events. Requests and services are usually server from the main thread but some service requests result in new threads being spawned.
+
+To allow for operations to run on the Main thread, fdevent features a RunQueue combined with an interrupt fd to force polling to return.
+
+```
++------------+    +-------------------------^
+|  RUNQUEUE  |    |                         |
++------------+    |  POLLING (Main thread)  |

++------------+      |       |       |       |

+|Interrupt fd+------+  +----+  +----+  +----+
++------------+         fd      Socket  Pipe
+```
+
+## ASOCKET, APACKET, and AMESSAGE
+
+The asocket, apacket, and amessage constructs exist only to wrap data while it transits on a Transport. An asocket handles a stream of apackets. An apacket consists in a amessage header featuring a command (`A_SYNC`, `A_OPEN`, `A_CLSE`, `A_WRTE`, `A_OKAY`, ...) followed by a payload (find more documentation in [protocol.txt](protocol.txt). There is no `A_READ` command because an asocket is unidirectional. To model a bi-directional stream, asocket have a peer which go in the opposite direction.
+
+An asocket features a buffer where the elemental unit is an apacket. Is traffic is inbound, the buffer stores apacket until they are consumed. If the traffic is oubound, the buffer store apackets until they are sent down the wire (with `A_WRTE` commands).
+
+```
++---------------------ASocket------------------------+
+ |                                                   |
+ | +----------------APacket Queue------------------+ |
+ | |                                               | |
+ | |            APacket     APacket     APacket    | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |          |AMessage|  |AMessage|  |AMessage|   | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |          |        |  |        |  |        |   | |
+ | |  .....   |        |  |        |  |        |   | |
+ | |          |  Data  |  |  Data  |  |  Data  |   | |
+ | |          |        |  |        |  |        |   | |
+ | |          |        |  |        |  |        |   | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |                                               | |
+ | +-----------------------------------------------+ |
+ +---------------------------------------------------+
+```
+
+This system allows to multiplex data streams on an unique byte stream.  Without entering too much into details, the amessage fields arg1 and arg2 are used alike in the TCP protocol where local and remote ports identify an unique stream. Note that unlike TCP which feature an "unacknowledged-send window", an apacket is sent only after the previous one has been confirmed to be received.
+
+The two types of asocket (Remote and Local) differentiate between outbound and inbound traffic.

+ * 4: We need to assign new_chunk for a corresponding old_chunk
+ * 5: The algorithm is similar to how kernel assigns chunk number
+ *    while creating exceptions.
+ * 6: Use a monotonically increasing chunk number to assign the
+ *    new_chunk
+ * 7: Each chunk-id represents either a: Metadata page or b: Data page
+ * 8: Chunk-id representing a data page is stored in a vector. Index is the
+ *    chunk-id and value is the pointer to the CowOperation
+ * 9: Chunk-id representing a metadata page is converted into a vector
+ *    index. We store this in vector as kernel requests metadata during

+ *       a: When initial dm-snapshot device is created, kernel requests
+ *          all the metadata and stores it in its internal data-structures.
+ *       b: During merge, kernel once again requests the same metadata
+ *          once-again.
+ *    In both these cases, a quick lookup based on chunk-id is done.
+ * 10: When chunk number is incremented, we need to make sure that
+ *    if the chunk is representing a metadata page and skip.
+ * 11: Each 4k page will contain 256 disk exceptions. We call this
+ *    exceptions_per_area_
+ * 12: Kernel will stop issuing metadata IO request when new-chunk ID is 0.

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner

-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and

-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-** --------------------------------------------
-** Support for Arm64 in GGLAssembler JIT
-** --------------------------------------------
-**
-** Approach
-** - GGLAssembler and associated files are largely un-changed.
-** - A translator class maps ArmAssemblerInterface calls to
-**   generate Arm64 instructions.
-**
-** ----------------------
-** ArmToArm64Assembler
-** ----------------------
-**
-** - Subclassed from ArmAssemblerInterface
-**
-** - Translates each ArmAssemblerInterface call to generate
-**   one or more Arm64 instructions  as necessary.
-**
-** - Does not implement ArmAssemblerInterface portions unused by GGLAssembler
-**   It calls NOT_IMPLEMENTED() for such cases, which in turn logs
-**    a fatal message.
-**
-** - Uses A64_.. series of functions to generate instruction machine code
-**   for Arm64 instructions. These functions also log the instruction
-**   to LOG, if ARM64_ASM_DEBUG define is set to 1
-**
-** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
-**   It uses arm64_disassemble to perform disassembly
-**
-** - Uses register 13 (SP in ARM), 15 (PC in ARM), 16, 17 for storing
-**   intermediate results. GGLAssembler does not use SP and PC as these
-**   registers are marked as reserved. The temporary registers are not
-**   saved/restored on stack as these are caller-saved registers in Arm64
-**
-** - Uses CSEL instruction to support conditional execution. The result is
-**   stored in a temporary register and then copied to the target register
-**   if the condition is true.
-**
-** - In the case of conditional data transfer instructions, conditional
-**   branch is used to skip over instruction, if the condition is false
-**
-** - Wherever possible, immediate values are transferred to temporary
-**   register prior to processing. This simplifies overall implementation
-**   as instructions requiring immediate values are converted to
-**   move immediate instructions followed by register-register instruction.
-**
-** --------------------------------------------
-** ArmToArm64Assembler unit test bench
-** --------------------------------------------
-**
-** - Tests ArmToArm64Assembler interface for all the possible
-**   ways in which GGLAssembler uses ArmAssemblerInterface interface.
-**
-** - Uses test jacket (written in assembly) to set the registers,
-**   condition flags prior to calling generated instruction. It also
-**   copies registers and flags at the end of execution. Caller then
-**   checks if generated code performed correct operation based on
-**   output registers and flags.
-**
-** - Broadly contains three type of tests, (i) data operation tests
-**   (ii) data transfer tests and (iii) LDM/STM tests.
-**
-** ----------------------
-** Arm64 disassembler
-** ----------------------
-** - This disassembler disassembles only those machine codes which can be
-**   generated by ArmToArm64Assembler. It has a unit testbench which
-**   tests all the instructions supported by the disassembler.
-**
-** ------------------------------------------------------------------
-** ARMAssembler/ARMAssemblerInterface/ARMAssemblerProxy changes
-** ------------------------------------------------------------------
-**
-** - In existing code, addresses were being handled as 32 bit values at
-**   certain places.
-**
-** - Added a new set of functions for address load/store/manipulation.
-**   These are ADDR_LDR, ADDR_STR, ADDR_ADD, ADDR_SUB and they map to
-**   default 32 bit implementations in ARMAssemblerInterface.
-**
-** - ArmToArm64Assembler maps these functions to appropriate 64 bit
-**   functions.
-**
-** ----------------------
-** GGLAssembler changes
-** ----------------------
-** - Since ArmToArm64Assembler can generate 4 Arm64 instructions for
-**   each call in worst case, the memory required is set to 4 times
-**   ARM memory
-**
-** - Address load/store/manipulation were changed to use new functions
-**   added in the ARMAssemblerInterface.

-/* MIPS assembler and ARM->MIPS assembly translator
-**
-** The approach is to leave the GGLAssembler and associated files largely
-** un-changed, still utilizing all Arm instruction generation. Via the
-** ArmToMipsAssembler (subclassed from ArmAssemblerInterface) each Arm
-** instruction is translated to one or more Mips instructions as necessary. This
-** is clearly less efficient than a direct implementation within the
-** GGLAssembler, but is far cleaner, more maintainable, and has yielded very
-** significant performance gains on Mips compared to the generic pixel pipeline.
-**
-**
-** GGLAssembler changes
-**
-** - The register allocator has been modified to re-map Arm registers 0-15 to mips
-** registers 2-17. Mips register 0 cannot be used as general-purpose register,
-** and register 1 has traditional uses as a short-term temporary.
-**
-** - Added some early bailouts for OUT_OF_REGISTERS in texturing.cpp and
-** GGLAssembler.cpp, since this is not fatal, and can be retried at lower
-** optimization level.
-**
-**
-** ARMAssembler and ARMAssemblerInterface changes
-**
-** Refactored ARM address-mode static functions (imm(), reg_imm(), imm12_pre(), etc.)
-** to virtual, so they can be overridden in MIPSAssembler. The implementation of these
-** functions on ARM is moved from ARMAssemblerInterface.cpp to ARMAssembler.cpp, and
-** is unchanged from the original. (This required duplicating 2 of these as static
-** functions in ARMAssemblerInterface.cpp so they could be used as static initializers).

-** To that end, there is no need for floating point, or priviledged

-**
-** The syntax makes no attempt to be as complete as the assember, with
-** synthetic instructions, and automatic recognition of immedate operands
-** (use the immediate form of the instruction), etc.
-**
-** We start with mips32r1, and may add r2 and dsp extensions if cpu

-** options. (makes sense since android will be built for a a specific

- *
- * Especially the lines defining and using GGL_RESERVE_NEEDS
- *
- * Quick reminders:
- *   - the last nibble of the first value is the destination buffer format.
- *   - the last nibble of the third value is the source texture format
- *   - formats: 4=rgb565 1=abgr8888 2=xbgr8888
- *
- * In the descriptions below:
- *
- *   SRC      means we copy the source pixels to the destination
- *
- *   SRC_OVER means we blend the source pixels to the destination
- *            with dstFactor = 1-srcA, srcFactor=1  (premultiplied source).
- *            This mode is otherwise called 'blend'.
- *
- *   SRCA_OVER means we blend the source pixels to the destination
- *             with dstFactor=srcA*(1-srcA) srcFactor=srcA (non-premul source).
- *             This mode is otherwise called 'blend_srca'
- *
- *   clamp    means we fetch source pixels from a texture with u/v clamping
- *
- *   mod      means the source pixels are modulated (multiplied) by the
- *            a/r/g/b of the current context's color. Typically used for
- *            fade-in / fade-out.
- *
- *   dither   means we dither 32 bit values to 16 bits
