The frame 66 * descriptions are separated from one another via a comma. The 67 * beginning of a frame description requires the specification 68 * of the graphic format and then the display frame rectangle where 69 * the frame will be displayed. The display frame rectangle is 70 * specified as follows, with the right and bottom coordinates being 71 * exclusive values: 72 * 73 * [left, top, right, bottom] 74 * 75 * After these two required parameters each frame description can 76 * specify 1 or more optional attributes. The name of each optional 77 * attribute is preceded by a colon. The current implementation 78 * then requires white space after the colon and then the value of 79 * the attribute is specified. See the synopsis section above for 80 * a list of attributes and the format of their expected value. 81 */ 82 83 #define LOG_TAG "hwcRectsTest" 84 85 #include <algorithm> 86 #include <assert.h> 87 #include <cerrno> 88 #include <cmath> 89 #include <cstdlib> 90 #include <ctime> 91 #include <istream> 92 #include <libgen.h> 93 #include <list> 94 #include <sched.h> 95 #include <sstream> 96 #include <stdint.h> 97 #include <string.h> 98 #include <unistd.h> 99 100 #include <sys/syscall.h> 101 #include <sys/types.h> 102 #include <sys/wait.h> 103 104 #include <EGL/egl.h> 105 #include <EGL/eglext.h> 106 #include <GLES2/gl2.h> 107 #include <GLES2/gl2ext.h> 108 109 #include <ui/GraphicBuffer.h> 110 #include <utils/Log.h> 111 #include <testUtil.h> 112 113 #include <hardware/hwcomposer.h> 114 115 #include <glTestLib.h> 116 #include "hwcTestLib.h" 117 118 using namespace std; 119 using namespace android; 120 121 // Defaults 122 const bool defaultVerbose = false; 123 const float defaultEndDelay = 2.0; // Default delay after rendering graphics 124 125 const uint32_t defaultFormat = HAL_PIXEL_FORMAT_RGBA_8888; 126 const int32_t defaultTransform = 0; 127 const uint32_t defaultBlend = HWC_BLENDING_NONE; 128 const ColorFract defaultColor(0.5, 0.5, 0.5); 129 const float defaultAlpha = 1.0; // Opaque 130 const HwcTestDim defaultSourceDim(1, 1); 131 const struct hwc_rect defaultSourceCrop = {0, 0, 1, 1}; 132 const struct hwc_rect defaultDisplayFrame = {0, 0, 100, 100}; 133 134 // Defines 135 #define MAXCMD 200 136 #define CMD_STOP_FRAMEWORK "stop 2>&1" 137 #define CMD_START_FRAMEWORK "start 2>&1" 138 139 // Macros 140 #define NUMA(a) (sizeof(a) / sizeof(a [0])) // Num elements in an array 141 142 // Local types 143 class Rectangle { 144 public: 145 Rectangle() : format(defaultFormat), transform(defaultTransform), 146 blend(defaultBlend), color(defaultColor), 147 alpha(defaultAlpha), sourceDim(defaultSourceDim), 148 sourceCrop(defaultSourceCrop), 149 displayFrame(defaultDisplayFrame) {}; 150 151 uint32_t format; 152 uint32_t transform; 153 int32_t blend; 154 ColorFract color; 155 float alpha; 156 HwcTestDim sourceDim; 157 struct hwc_rect sourceCrop; 158 struct hwc_rect displayFrame; 159 160 sp<GraphicBuffer> texture; 161 }; 162 163 // Globals 164 list<Rectangle> rectangle; 165 static const int texUsage = GraphicBuffer::USAGE_HW_TEXTURE | 166 GraphicBuffer::USAGE_SW_WRITE_RARELY; 167 static hwc_composer_device_1_t *hwcDevice; 168 static EGLDisplay dpy; 169 static EGLSurface surface; 170 static EGLint width, height; 171 172 // Function prototypes 173 static Rectangle parseRect(string rectStr); 174 void init(void); 175 void printSyntax(const char *cmd); 176 177 // Command-line option settings 178 static bool verbose = defaultVerbose; 179 static float endDelay = defaultEndDelay; 180 181 /* 182 * Main 183 * 184 * Performs the following high-level sequence of operations: 185 * 186 * 1.
