Before rendering a set of overlays, the HWC is shown - * the list through a prepare call. During the prepare call the HWC - * is able to examine the list and specify which overlays it is able - * to handle. The overlays that it can't handle are typically composited - * by a higher level (e.g. Surface Flinger) and then the original list - * plus a composit of what HWC passed on are provided back to the HWC - * for rendering. - * - * Once an implementation of the HWC has been shipped, a regression would - * likely occur if a latter implementation started passing on conditions - * that it used to commit to. The primary purpose of this benchmark - * is the automated discovery of the commit points, where an implementation - * is on the edge between committing and not committing. These are commonly - * referred to as commit points. Between implementations changes to the - * commit points are allowed, as long as they improve what the HWC commits - * to. Once an implementation of the HWC is shipped, the commit points are - * not allowed to regress in future implementations. - * - * This benchmark takes a sampling and then adjusts until it finds a - * commit point. It doesn't exhaustively check all possible conditions, - * which do to the number of combinations would be impossible. Instead - * it starts its search from a starting dimension, that can be changed - * via the -s option. The search is also bounded by a set of search - * limits, that are hard-coded into a structure of constants named - * searchLimits. Results that happen to reach a searchLimit are prefixed - * with >=, so that it is known that the value could possibly be larger. - * - * Measurements are made for each of the graphic formats specified as - * positional parameters on the command-line. If no graphic formats - * are specified on the command line, then by default measurements are - * made and reported for each of the known graphic format. - */ - -#include <algorithm> -#include <assert.h> -#include <cerrno> -#include <cmath> -#include <cstdlib> -#include <ctime> -#include <iomanip> -#include <istream> -#include <libgen.h> -#include <list> -#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 "hwcCommitTest" -#include <utils/Log.h> -#include <testUtil.h> - -#include <hardware/hwcomposer.h> - -#include <glTestLib.h> -#include "hwcTestLib.h" - -using namespace std;
