+/**
+ * We use the BufferCache to reduce the overhead of exchanging GraphicBuffers with
+ * the server. If we were to simply parcel the GraphicBuffer we would pay two overheads
+ *     1. Cost of sending the FD
+ *     2. Cost of importing the GraphicBuffer with the mapper in the receiving process.
+ * To ease this cost we implement the following scheme of caching buffers to integers,
+ * or said-otherwise, naming them with integers. This is the scheme known as slots in
+ * the legacy BufferQueue system.
+ *     1. When sending Buffers to SurfaceFlinger we look up the Buffer in the cache.
+ *     2. If there is a cache-hit we remove the Buffer from the Transaction and instead
+ *        send the cached integer.
+ *     3. If there is a cache miss, we cache the new buffer and send the integer
+ *        along with the Buffer, SurfaceFlinger on it's side creates a new cache
+ *        entry, and we use the integer for further communication.
+ * A few details about lifetime:
+ *     1. The cache evicts by LRU. The server side cache is keyed by BufferCache::getToken
+ *        which is per process Unique. The server side cache is larger than the client side
+ *        cache so that the server will never evict entries before the client.
+ *     2. When the client evicts an entry it notifies the server via an uncacheBuffer
+ *        transaction.
+ *     3. The client only references the Buffers by ID, and uses buffer->addDeathCallback
+ *        to auto-evict destroyed buffers.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      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
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   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.
+
+   END OF TERMS AND CONDITIONS

+/**
+ * CallOrderStateMachineHelper is a helper class for setting up a compile-time
+ * checked state machine that a sequence of calls is correct for completely
+ * setting up the state for some other type.
+ *
+ * Two examples where this could be used are with setting up a "Builder" flow
+ * for initializing an instance of some type, and writing tests where the state
+ * machine sets up expectations and preconditions, calls the function under
+ * test, and then evaluations postconditions.
+ *
+ * The purpose of this helper is to offload some of the boilerplate code to
+ * simplify the actual state classes, and is also a place to document how to
+ * go about setting up the state classes.
+ *
+ * To work at compile time, the idea is that each state is a unique C++ type,
+ * and the valid transitions between states are given by member functions on
+ * those types, with those functions returning a simple value type expressing
+ * the new state to use. Illegal state transitions become a compile error because
+ * a named member function does not exist.
+ *
+ * Example usage in a test:
+ *
+ *    A two step (+ terminator step) setup process can defined using:
+ *
+ *        class Step1 : public CallOrderStateMachineHelper<TestFixtureType, Step1> {
+ *           [[nodiscard]] auto firstMockCalledWith(int value1) {
+ *              // Set up an expectation or initial state using the fixture
+ *              EXPECT_CALL(getInstance->firstMock, FirstCall(value1));
+ *              return nextState<Step2>();
+ *           }
+ *        };
+ *
+ *        class Step2 : public CallOrderStateMachineHelper<TestFixtureType, Step2> {
+ *           [[nodiscard]] auto secondMockCalledWith(int value2) {
+ *              // Set up an expectation or initial state using the fixture
+ *              EXPECT_CALL(getInstance()->secondMock, SecondCall(value2));
+ *              return nextState<StepExecute>();
+ *           }
+ *        };
+ *
+ *        class StepExecute : public CallOrderStateMachineHelper<TestFixtureType, Step3> {
+ *           void execute() {
+ *              invokeFunctionUnderTest();
+ *           }
+ *        };
+ *
+ *    Note how the non-terminator steps return by value and use [[nodiscard]] to
+ *    enforce the setup flow. Only the terminator step returns void.
+ *
+ *    This can then be used in the tests with:
+ *
+ *        Step1::make(this).firstMockCalledWith(value1)
+ *                .secondMockCalledWith(value2)
+ *                .execute);
+ *
+ *    If the test fixture defines a `verify()` helper function which returns
+ *    `Step1::make(this)`, this can be simplified to:
+ *
+ *        verify().firstMockCalledWith(value1)
+ *                .secondMockCalledWith(value2)
+ *                .execute();
+ *
+ *    This is equivalent to the following calls made by the text function:
+ *
+ *        EXPECT_CALL(firstMock, FirstCall(value1));
+ *        EXPECT_CALL(secondMock, SecondCall(value2));
+ *        invokeFunctionUnderTest();

 This subdirectory contains Android's Vulkan loader, as well as some Vulkan-related tools useful to platform developers.
 
+## Documentation
+
+The former contents of doc/implementors_guide/ are now at https://source.android.com/devices/graphics/implement-vulkan.
+
 ## Coding Style
 
 We follow the [Chromium coding style](https://www.chromium.org/developers/coding-style) for naming and formatting, except with four-space indentation instead of two spaces. In general, any C++ features supported by the prebuilt platform toolchain are allowed.

 ## Code Generation
 
-We generate several parts of the loader and tools from a Vulkan API description file, stored in `api/vulkan.api`. Code generation must be done manually because the generator tools aren't part of the platform toolchain (yet?). Files named `foo_gen.*` are generated from the API file and a template file named `foo.tmpl`.
+We generate several parts of the loader and tools driectly from the Vulkan Registry (external/vulkan-headers/registry/vk.xml). Code generation must be done manually because the generator is not part of the platform toolchain (yet?). Files named `foo_gen.*` are generated by the code generator.
 
- To run the generator:
+### Run The Code Generator
 
-### One-time setup
-- Install [golang](https://golang.org/), if you don't have it already.
-- Create a directory (e.g. `$HOME/lib/go`) for local go sources and binaries and add it to `$GOPATH`.
-- `$ git clone https://android.googlesource.com/platform/tools/gpu $GOPATH/src/android.googlesource.com/platform/tools/gpu`
-- `$ go get android.googlesource.com/platform/tools/gpu/api/...`
-- You should now have `$GOPATH/bin/apic`. You might want to add `$GOPATH/bin` to your `$PATH`.
-
-### Generating code
-To generate `libvulkan/*_gen.*`,
-- `$ cd libvulkan`
-- `$ apic template ../api/vulkan.api code-generator.tmpl`
-Similar for `nulldrv/null_driver_gen.*`.
+Install Python3 (if not already installed) and execute below:
+`$ ./scripts/code_generator.py`
