- * This class supports storing entries with duplicate keys.  Of course, it can't

- *
- * One such assumption is that if you're getting file descriptors for
- * use with this class as a child of a fork() operation, you must be on
- * a pread() to guarantee correct operation. This is because pread() can
- * atomically read at a file offset without worrying about a lock around an
- * lseek() + read() pair.

+ * Solves a linear least squares problem to obtain a N degree polynomial that fits
+ * the specified input data as nearly as possible.
+ *
+ * Returns true if a solution is found, false otherwise.
+ *
+ * The input consists of two vectors of data points X and Y with indices 0..m-1
+ * along with a weight vector W of the same size.
+ *
+ * The output is a vector B with indices 0..n that describes a polynomial
+ * that fits the data, such the sum of W[i] * W[i] * abs(Y[i] - (B[0] + B[1] X[i]
+ * + B[2] X[i]^2 ... B[n] X[i]^n)) for all i between 0 and m-1 is minimized.
+ *
+ * Accordingly, the weight vector W should be initialized by the caller with the
+ * reciprocal square root of the variance of the error in each input data point.
+ * In other words, an ideal choice for W would be W[i] = 1 / var(Y[i]) = 1 / stddev(Y[i]).
+ * The weights express the relative importance of each data point.  If the weights are
+ * all 1, then the data points are considered to be of equal importance when fitting
+ * the polynomial.  It is a good idea to choose weights that diminish the importance
+ * of data points that may have higher than usual error margins.
+ *
+ * Errors among data points are assumed to be independent.  W is represented here
+ * as a vector although in the literature it is typically taken to be a diagonal matrix.
+ *
+ * That is to say, the function that generated the input data can be approximated
+ * by y(x) ~= B[0] + B[1] x + B[2] x^2 + ... + B[n] x^n.
+ *
+ * The coefficient of determination (R^2) is also returned to describe the goodness
+ * of fit of the model for the given data.  It is a value between 0 and 1, where 1
+ * indicates perfect correspondence.
+ *
+ * This function first expands the X vector to a m by n matrix A such that
+ * A[i][0] = 1, A[i][1] = X[i], A[i][2] = X[i]^2, ..., A[i][n] = X[i]^n, then
+ * multiplies it by w[i]./
+ *
+ * Then it calculates the QR decomposition of A yielding an m by m orthonormal matrix Q
+ * and an m by n upper triangular matrix R.  Because R is upper triangular (lower
+ * part is all zeroes), we can simplify the decomposition into an m by n matrix
+ * Q1 and a n by n matrix R1 such that A = Q1 R1.
+ *
+ * Finally we solve the system of linear equations given by R1 B = (Qtranspose W Y)
+ * to find B.
+ *
+ * For efficiency, we lay out A and Q column-wise in memory because we frequently
+ * operate on the column vectors.  Conversely, we lay out R row-wise.

-          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.
-

-Android Utility Function Library
-================================
-
-
-If you need a feature that is native to Linux but not present on other
-platforms, construct a platform-dependent implementation that shares
-the Linux interface.  That way the actual device runs as "light" as
-possible.
-
-If that isn't feasible, create a system-independent interface and hide
-the details.
-
-The ultimate goal is *not* to create a super-duper platform abstraction
-layer.  The goal is to provide an optimized solution for Linux with
-reasonable implementations for other platforms.
-
-
-
-Resource overlay
-================
-
-
-Introduction
-------------
-
-Overlay packages are special .apk files which provide no code but
-additional resource values (and possibly new configurations) for
-resources in other packages. When an application requests resources,
-the system will return values from either the application's original
-package or any associated overlay package. Any redirection is completely
-transparent to the calling application.
-
-Resource values have the following precedence table, listed in
-descending precedence.
-
- * overlay package, matching config (eg res/values-en-land)
-
- * original package, matching config
-
- * overlay package, no config (eg res/values)
-
- * original package, no config
-
-During compilation, overlay packages are differentiated from regular
-packages by passing the -o flag to aapt.
-
-
-Background
-----------
-
-This section provides generic background material on resources in
-Android.
-
-
-How resources are bundled in .apk files
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Android .apk files are .zip files, usually housing .dex code,
-certificates and resources, though packages containing resources but
-no code are possible. Resources can be divided into the following
-categories; a `configuration' indicates a set of phone language, display
-density, network operator, etc.
-
- * assets: uncompressed, raw files packaged as part of an .apk and
-           explicitly referenced by filename. These files are
-           independent of configuration.
-
- * res/drawable: bitmap or xml graphics. Each file may have different
-                 values depending on configuration.
-
- * res/values: integers, strings, etc. Each resource may have different
-               values depending on configuration.
-
-Resource meta information and information proper is stored in a binary
-format in a named file resources.arsc, bundled as part of the .apk.
-
-Resource IDs and lookup
-~~~~~~~~~~~~~~~~~~~~~~~
-During compilation, the aapt tool gathers application resources and
-generates a resources.arsc file. Each resource name is assigned an
-integer ID 0xppttiii (translated to a symbolic name via R.java), where
-
- * pp: corresponds to the package namespace (details below).
-
- * tt: corresponds to the resource type (string, int, etc). Every
-       resource of the same type within the same package has the same
-       tt value, but depending on available types, the actual numerical
-       value may be different between packages.
-
- * iiii: sequential number, assigned in the order resources are found.
-
-Resource values are specified paired with a set of configuration
-constraints (the default being the empty set), eg res/values-sv-port
-which imposes restrictions on language (Swedish) and display orientation
-(portrait). During lookup, every constraint set is matched against the
-current configuration, and the value corresponding to the best matching
-constraint set is returned (ResourceTypes.{h,cpp}).
-
-Parsing of resources.arsc is handled by ResourceTypes.cpp; this utility
-is governed by AssetManager.cpp, which tracks loaded resources per
-process.
-
-Assets are looked up by path and filename in AssetManager.cpp. The path
-to resources in res/drawable are located by ResourceTypes.cpp and then
-handled like assets by AssetManager.cpp. Other resources are handled
-solely by ResourceTypes.cpp.
-
-Package ID as namespace
-~~~~~~~~~~~~~~~~~~~~~~~
-The pp part of a resource ID defines a namespace. Android currently
-defines two namespaces:
-
- * 0x01: system resources (pre-installed in framework-res.apk)
-
- * 0x7f: application resources (bundled in the application .apk)
-
-ResourceTypes.cpp supports package IDs between 0x01 and 0x7f
-(inclusive); values outside this range are invalid.
-
-Each running (Dalvik) process is assigned a unique instance of
-AssetManager, which in turn keeps a forest structure of loaded
-resource.arsc files. Normally, this forest is structured as follows,
-where mPackageMap is the internal vector employed in ResourceTypes.cpp.
-
-mPackageMap[0x00] -> system package
-mPackageMap[0x01] -> NULL
-mPackageMap[0x02] -> NULL
-...
-mPackageMap[0x7f - 2] -> NULL
-mPackageMap[0x7f - 1] -> application package
-
-
-
-The resource overlay extension
-------------------------------
-
-The resource overlay mechanism aims to (partly) shadow and extend
-existing resources with new values for defined and new configurations.
-Technically, this is achieved by adding resource-only packages (called
-overlay packages) to existing resource namespaces, like so:
-
-mPackageMap[0x00] -> system package -> system overlay package
-mPackageMap[0x01] -> NULL
-mPackageMap[0x02] -> NULL
-...
-mPackageMap[0x7f - 2] -> NULL
-mPackageMap[0x7f - 1] -> application package -> overlay 1 -> overlay 2
-
-The use of overlay resources is completely transparent to
-applications; no additional resource identifiers are introduced, only
-configuration/value pairs. Any number of overlay packages may be loaded
-at a time; overlay packages are agnostic to what they target -- both
-system and application resources are fair game.
-
-The package targeted by an overlay package is called the target or
-original package.
-
-Resource overlay operates on symbolic resources names. Hence, to
-override the string/str1 resources in a package, the overlay package
-would include a resource also named string/str1. The end user does not
-have to worry about the numeric resources IDs assigned by aapt, as this
-is resolved automatically by the system.
-
-As of this writing, the use of resource overlay has not been fully
-explored. Until it has, only OEMs are trusted to use resource overlay.
-For this reason, overlay packages must reside in /system/overlay.
-
-
-Resource ID mapping
-~~~~~~~~~~~~~~~~~~~
-Resource identifiers must be coherent within the same namespace (ie
-PackageGroup in ResourceTypes.cpp). Calling applications will refer to
-resources using the IDs defined in the original package, but there is no
-guarantee aapt has assigned the same ID to the corresponding resource in
-an overlay package. To translate between the two, a resource ID mapping
-{original ID -> overlay ID} is created during package installation
-(PackageManagerService.java) and used during resource lookup. The
-mapping is stored in /data/resource-cache, with a @idmap file name
-suffix.
-
-The idmap file format is documented in a separate section, below.
-
-
-Package management
-~~~~~~~~~~~~~~~~~~
-Packages are managed by the PackageManagerService. Addition and removal
-of packages are monitored via the inotify framework, exposed via
-android.os.FileObserver.
-
-During initialization of a Dalvik process, ActivityThread.java requests
-the process' AssetManager (by proxy, via AssetManager.java and JNI)
-to load a list of packages. This list includes overlay packages, if
-present.
-
-When a target package or a corresponding overlay package is installed,
-the target package's process is stopped and a new idmap is generated.
-This is similar to how applications are stopped when their packages are
-upgraded.
-
-
-Creating overlay packages
--------------------------
-
-Overlay packages should contain no code, define (some) resources with
-the same type and name as in the original package, and be compiled with
-the -o flag passed to aapt.
-
-The aapt -o flag instructs aapt to create an overlay package.
-Technically, this means the package will be assigned package id 0x00.
-
-There are no restrictions on overlay packages names, though the naming
-convention <original.package.name>.overlay.<name> is recommended.
-
-
-Example overlay package
-~~~~~~~~~~~~~~~~~~~~~~~
-
-To overlay the resource bool/b in package com.foo.bar, to be applied
-when the display is in landscape mode, create a new package with
-no source code and a single .xml file under res/values-land, with
-an entry for bool/b. Compile with aapt -o and place the results in
-/system/overlay by adding the following to Android.mk:
-
-LOCAL_AAPT_FLAGS := -o com.foo.bar
-LOCAL_MODULE_PATH := $(TARGET_OUT)/overlay
-
-
-The ID map (idmap) file format
-------------------------------
-
-The idmap format is designed for lookup performance. However, leading
-and trailing undefined overlay values are discarded to reduce the memory
-footprint.
-
-
-idmap grammar
-~~~~~~~~~~~~~
-All atoms (names in square brackets) are uint32_t integers. The
-idmap-magic constant spells "idmp" in ASCII. Offsets are given relative
-to the data_header, not to the beginning of the file.
-
-map          := header data
-header       := idmap-magic <crc32-original-pkg> <crc32-overlay-pkg>
-idmap-magic  := <0x706d6469>
-data         := data_header type_block+
-data_header  := <m> header_block{m}
-header_block := <0> | <type_block_offset>
-type_block   := <n> <id_offset> entry{n}
-entry        := <resource_id_in_target_package>
-
-
-idmap example
-~~~~~~~~~~~~~
-Given a pair of target and overlay packages with CRC sums 0x216a8fe2
-and 0x6b9beaec, each defining the following resources
-
-Name          Target package  Overlay package
-string/str0   0x7f010000      -
-string/str1   0x7f010001      0x7f010000
-string/str2   0x7f010002      -
-string/str3   0x7f010003      0x7f010001
-string/str4   0x7f010004      -
-bool/bool0    0x7f020000      -
-integer/int0  0x7f030000      0x7f020000
-integer/int1  0x7f030001      -
-
-the corresponding resource map is
-
-0x706d6469 0x216a8fe2 0x6b9beaec 0x00000003 \
-0x00000004 0x00000000 0x00000009 0x00000003 \
-0x00000001 0x7f010000 0x00000000 0x7f010001 \
-0x00000001 0x00000000 0x7f020000
-
-or, formatted differently
-
-0x706d6469  # magic: all idmap files begin with this constant
-0x216a8fe2  # CRC32 of the resources.arsc file in the original package
-0x6b9beaec  # CRC32 of the resources.arsc file in the overlay package
-0x00000003  # header; three types (string, bool, integer) in the target package
-0x00000004  #   header_block for type 0 (string) is located at offset 4
-0x00000000  #   no bool type exists in overlay package -> no header_block

-0x00000003  # header_block for string; overlay IDs span 3 elements

+    3. Should the presentation time be state which is used by eglSwapBuffers,
+    or should it be a new parameter to an extended variant of eglSwapBuffers?
+
+    RESOLVED: The presentation time should be new state which is used by
+    the existing eglSwapBuffers call. Adding new state composes better with
+    other (hypothetical) extensions that also modify the behavior of
+    eglSwapBuffers.

 Revision History
 
-#1 (Jamie Gennis, April 1, 2013)
+#3 (Jesse Hall, June 26, 2013)
+    - Enumerated errors generated by eglPresentationTimeANDROID.
+    - Added Issue #3 with resolution.
+
+#2 (Jamie Gennis, April 1, 2013)
     - Clarified how uses that either do or do not need an absolute time should
       be handled.
     - Specified the eglPresentationTimeANDROID return value.

-/* This DisplaySurface implementation is a stub used for developing HWC
- * virtual display support. It is currently just a passthrough.
+/* This DisplaySurface implementation supports virtual displays, where GLES
+ * and/or HWC compose into a buffer that is then passed to an arbitrary
+ * consumer (the sink) running in another process.
+ *
+ * The simplest case is when the virtual display will never use the h/w
+ * composer -- either the h/w composer doesn't support writing to buffers, or
+ * there are more virtual displays than it supports simultaneously. In this
+ * case, the GLES driver works directly with the output buffer queue, and
+ * calls to the VirtualDisplay from SurfaceFlinger and DisplayHardware do
+ * nothing.
+ *
+ * If h/w composer might be used, then each frame will fall into one of three
+ * configurations: GLES-only, HWC-only, and MIXED composition. In all of these,
+ * we must provide a FB target buffer and output buffer for the HWC set() call.
+ *
+ * In GLES-only composition, the GLES driver is given a buffer from the sink to
+ * render into. When the GLES driver queues the buffer to the
+ * VirtualDisplaySurface, the VirtualDisplaySurface holds onto it instead of
+ * immediately queueing it to the sink. The buffer is used as both the FB
+ * target and output buffer for HWC, though on these frames the HWC doesn't
+ * do any work for this display and doesn't write to the output buffer. After
+ * composition is complete, the buffer is queued to the sink.
+ *
+ * In HWC-only composition, the VirtualDisplaySurface dequeues a buffer from
+ * the sink and passes it to HWC as both the FB target buffer and output
+ * buffer. The HWC doesn't need to read from the FB target buffer, but does
+ * write to the output buffer. After composition is complete, the buffer is
+ * queued to the sink.
+ *
+ * On MIXED frames, things become more complicated, since some h/w composer
+ * implementations can't read from and write to the same buffer. This class has
+ * an internal BufferQueue that it uses as a scratch buffer pool. The GLES
+ * driver is given a scratch buffer to render into. When it finishes rendering,
+ * the buffer is queued and then immediately acquired by the
+ * VirtualDisplaySurface. The scratch buffer is then used as the FB target
+ * buffer for HWC, and a separate buffer is dequeued from the sink and used as
+ * the HWC output buffer. When HWC composition is complete, the scratch buffer
+ * is released and the output buffer is queued to the sink.
