The first frame is rendered 43 * in the upper third of the display and is called the reference frame. 44 * The second frame is displayed in the middle third and is called the 45 * equivalence frame. The primary purpose of this utility is to verify 46 * that the colors produced in the reference and equivalence frames are 47 * the same. The colors are the same when the colors are the same 48 * vertically between the reference and equivalence frames. 49 * 50 * By default the reference frame is rendered through the use of the 51 * RGBA8888 graphic format. The -r option can be used to specify a 52 * non-default reference frame graphic format. The graphic format of 53 * the equivalence frame is determined by a single required positional 54 * parameter. Intentionally there is no default for the graphic format 55 * of the equivalence frame. 56 * 57 * The horizontal blend in the reference frame is produced from a linear 58 * interpolation from a start color (default: <0.0, 0.0, 0.0> on the left 59 * side to an end color (default <1.0, 1.0, 1.0> on the right side. Where 60 * possible the equivalence frame is rendered with the equivalent color 61 * from the reference frame. A color of black is used in the equivalence 62 * frame for cases where an equivalent color does not exist. 63 */ 64 65 #include <algorithm> 66 #include <assert.h> 67 #include <cerrno> 68 #include <cmath> 69 #include <cstdlib> 70 #include <ctime> 71 #include <libgen.h> 72 #include <sched.h> 73 #include <sstream> 74 #include <stdint.h> 75 #include <string.h> 76 #include <unistd.h> 77 #include <vector> 78 79 #include <sys/syscall.h> 80 #include <sys/types.h> 81 #include <sys/wait.h> 82 83 #include <EGL/egl.h> 84 #include <EGL/eglext.h> 85 #include <GLES2/gl2.h> 86 #include <GLES2/gl2ext.h> 87 88 #include <ui/FramebufferNativeWindow.h> 89 #include <ui/GraphicBuffer.h> 90 91 #define LOG_TAG "hwcColorEquivTest" 92 #include <utils/Log.h> 93 #include <testUtil.h> 94 95 #include <hardware/hwcomposer.h> 96 97 #include "hwcTestLib.h" 98 99 using namespace std; 100 using namespace android; 101 102 // Defaults for command-line options 103 const bool defaultVerbose = false; 104 const ColorFract defaultStartColor(0.0, 0.0, 0.0); 105 const ColorFract defaultEndColor(1.0, 1.0, 1.0); 106 const char *defaultRefFormat = "RGBA8888"; 107 const float defaultEndDelay = 2.0; // Default delay after rendering graphics 108 109 // Defines 110 #define MAXSTR 100 111 #define MAXCMD 200 112 #define BITSPERBYTE 8 // TODO: Obtain from <values.h>, once 113 // it has been added 114 115 #define CMD_STOP_FRAMEWORK "stop 2>&1" 116 #define CMD_START_FRAMEWORK "start 2>&1" 117 118 // Macros 119 #define NUMA(a) (sizeof(a) / sizeof(a [0])) // Num elements in an array 120 #define MEMCLR(addr, size) do { \ 121 memset((addr), 0, (size)); \ 122 } while (0) 123 124 // Globals 125 static const int texUsage = GraphicBuffer::USAGE_HW_TEXTURE | 126 GraphicBuffer::USAGE_SW_WRITE_RARELY; 127 static hwc_composer_device_1_t *hwcDevice; 128 static EGLDisplay dpy; 129 static EGLSurface surface; 130 static EGLint width, height; 131 132 // Functions prototypes 133 void init(void); 134 void printSyntax(const char *cmd); 135 136 // Command-line option settings 137 static bool verbose = defaultVerbose; 138 static ColorFract startRefColor = defaultStartColor; 139 static ColorFract endRefColor = defaultEndColor; 140 static float endDelay = defaultEndDelay; 141 static const struct hwcTestGraphicFormat *refFormat 142 = hwcTestGraphicFormatLookup(defaultRefFormat); 143 static const struct hwcTestGraphicFormat *equivFormat; 144 145 /* 146 * Main 147 * 148 * Performs the following high-level sequence of operations: 149 * 150 * 1.
