-/**
- * MemoryPressureWatcher watches sysfs from its own thread to notice when the
- * system is under memory pressure.  When we observe memory pressure, we use
- * MemoryPressureRunnable to notify observers that they should release memory.
- *
- * When the system is under memory pressure, we don't want to constantly fire
- * memory-pressure events.  So instead, we try to detect when sysfs indicates
- * that we're no longer under memory pressure, and only then start firing events
- * again.
- *
- * (This is a bit problematic because we can't poll() to detect when we're no
- * longer under memory pressure; instead we have to periodically read the sysfs
- * node.  If we remain under memory pressure for a long time, this means we'll
- * continue waking up to read from the node for a long time, potentially wasting
- * battery life.  Hopefully we don't hit this case in practice!  We write to
- * logcat each time we go around this loop so it's at least noticable.)
- *
- * Shutting down safely is a bit of a chore.  XPCOM won't shut down until all
- * threads exit, so we need to exit the Run() method below on shutdown.  But our
- * thread might be blocked in one of two situations: We might be poll()'ing the
- * sysfs node waiting for memory pressure to occur, or we might be asleep
- * waiting to read() the sysfs node to see if we're no longer under memory
- * pressure.
- *
- * To let us wake up from the poll(), we poll() not just the sysfs node but also
- * a pipe, which we write to on shutdown.  To let us wake up from sleeping
- * between read()s, we sleep by Wait()'ing on a monitor, which we notify on
- * shutdown.

- * hwcomposer.h defines an interface for display composition
- * using dedicated hardware. This hardware is usually faster
- * or more power efficient than the GPU. However, in exchange
- * for better performance, generality has to be sacrificed:
- * no 3d transforms, no intermediate surfaces, no special shader effects,
- * and loss of other goodies depending on the platform.
- *
- * In general, when hwc is enabled gecko tries to compose
- * its frames using HwcComposer2D first. Then if HwcComposer2D is
- * unable to compose a frame then it falls back to compose it
- * using the GPU with OpenGL.

-/* 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.

- * 2. The InputDispatcherThread (called "InputDispatcher") thread waits for new events on the

- * into the InputDispatcherThread and never the reverse.  Both classes may interact with the
- * InputDispatchPolicy, however.

-/**
- * 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.

- * The ATRACE_TAG macro can be defined before including this header to trace

- * userland to avoid some of the runtime cost of tracing when it is not desired.
- *
- * Defining ATRACE_TAG to be ATRACE_TAG_ALWAYS will result in the tracing always
- * being enabled - this should ONLY be done for debug code, as userland tracing
- * has a performance cost even when the trace is not being recorded.  Defining
- * ATRACE_TAG to be ATRACE_TAG_NEVER or leaving ATRACE_TAG undefined will result
- * in the tracing always being disabled.
- *
- * ATRACE_TAG_HAL should be bitwise ORed with the relevant tags for tracing
- * within a hardware module.  For example a camera hardware module would set:
- * #define ATRACE_TAG  (ATRACE_TAG_CAMERA | ATRACE_TAG_HAL)
- *
- * Keep these in sync with frameworks/base/core/java/android/os/Trace.java.
