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> +#include <ui/EGLUtils.h> + +#define LOG_TAG "hwcStressTest" +#include <utils/Log.h> +#include <testUtil.h> + +#include <hardware/hwcomposer.h> + +#include <glTestLib.h> +#include <hwc/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.
