By default the period of time is FLT_MAX, - * so that the number of passes will take precedence. - * - * The passes are grouped together, where (pass / passesPerGroup) specifies - * which group a particular pass is in. This causes every passesPerGroup - * worth of sequential passes to be within the same group. Computationally - * intensive operations are performed just once at the beginning of a group - * of passes and then used by all the passes in that group. This is done - * so as to increase both the average and peak rate of graphic operations, - * by moving computationally intensive operations to the beginning of a group. - * In particular, at the start of each group of passes a set of - * graphic buffers are created, then used by the first and remaining - * passes of that group of passes. - * - * The per-group initialization of the graphic buffers is performed - * by a function called initFrames. This function creates an array - * of smart pointers to the graphic buffers, in the form of a vector - * of vectors. The array is accessed in row major order, so each - * row is a vector of smart pointers. All the pointers of a single - * row point to graphic buffers which use the same pixel format and - * have the same dimension, although it is likely that each one is - * filled with a different color. This is done so that after doing - * the first HWC prepare then set call, subsequent set calls can - * be made with each of the layer handles changed to a different - * graphic buffer within the same row. Since the graphic buffers - * in a particular row have the same pixel format and dimension, - * additional HWC set calls can be made, without having to perform - * an HWC prepare call. - * - * This test supports the following command-line options: - * - * -v Verbose - * -s num Starting pass - * -e num Ending pass - * -p num Execute the single pass specified by num - * -n num Number of set operations to perform after each prepare operation - * -t float Maximum time in seconds to execute the test - * -d float Delay in seconds performed after each set operation - * -D float Delay in seconds performed after the last pass is executed - * - * Typically the test is executed for a large range of passes. By default - * passes 0 through 99999 (100,000 passes) are executed. Although this test - * does not validate the generated image, at times it is useful to reexecute - * a particular pass and leave the displayed image on the screen for an - * extended period of time. This can be done either by setting the -s - * and -e options to the desired pass, along with a large value for -D. - * This can also be done via the -p option, again with a large value for - * the -D options. - * - * So far this test only contains code to create graphic buffers with - * a continuous solid color. Although this test is unable to validate the - * image produced, any image that contains other than rectangles of a solid - * color are incorrect. Note that the rectangles may use a transparent - * color and have a blending operation that causes the color in overlapping - * rectangles to be mixed. In such cases the overlapping portions may have - * a different color from the rest of the rectangle. - */ - -#include <algorithm> -#include <assert.h> -#include <cerrno> -#include <cmath> -#include <cstdlib> -#include <ctime> -#include <libgen.h> -#include <sched.h> -#include <sstream> -#include <stdint.h> -#include <string.h> -#include <unistd.h> -#include <vector> - -#include <sys/syscall.h> -#include <sys/types.h> -#include <sys/wait.h> - -#include <EGL/egl.h> -#include <EGL/eglext.h> -#include <GLES2/gl2.h> -#include <GLES2/gl2ext.h> - -#include <ui/FramebufferNativeWindow.h> -#include <ui/GraphicBuffer.h> - -#define LOG_TAG "hwcStressTest" -#include <utils/Log.h> -#include <testUtil.h> - -#include <hardware/hwcomposer.h> - -#include <glTestLib.h> -#include "hwcTestLib.h" - -using namespace std; -using namespace android; - -const float maxSizeRatio = 1.3; // Graphic buffers can be upto this munch - // larger than the default screen size -const unsigned int passesPerGroup = 10; // A group of passes all use the same - // graphic buffers - -// Ratios at which rare and frequent conditions should be produced -const float rareRatio = 0.1; -const float freqRatio = 0.9; - -// Defaults for command-line options -const bool defaultVerbose = false; -const unsigned int defaultStartPass = 0; -const unsigned int defaultEndPass = 99999; -const unsigned int defaultPerPassNumSet = 10; -const float defaultPerSetDelay = 0.0; // Default delay after each set - // operation.
