The program also allows test testing of the 31 * memory management and mode setting APIs by allowing the user to specify a 32 * connector and mode to use for mode setting. If all works as expected, a 33 * blue background should be painted on the monitor attached to the specified 34 * connector after the selected mode is set. 35 * 36 * TODO: use cairo to write the mode info on the selected output once 37 * the mode has been programmed, along with possible test patterns. 38 */ 39 40#include <errno.h> 41#include <stdint.h> 42#include <stdio.h> 43#include <stdlib.h> 44#include <string.h> 45 46#include "xf86drm.h" 47#include "xf86drmMode.h" 48 49#include "common.h" 50 51struct type_name { 52 unsigned int type; 53 const char *name; 54}; 55 56static const char *util_lookup_type_name(unsigned int type, 57 const struct type_name *table, 58 unsigned int count) 59{ 60 unsigned int i; 61 62 for (i = 0; i < count; i++) 63 if (table[i].type == type) 64 return table[i].name; 65 66 return NULL; 67} 68 69static const struct type_name encoder_type_names[] = { 70 { DRM_MODE_ENCODER_NONE, "none" }, 71 { DRM_MODE_ENCODER_DAC, "DAC" }, 72 { DRM_MODE_ENCODER_TMDS, "TMDS" }, 73 { DRM_MODE_ENCODER_LVDS, "LVDS" }, 74 { DRM_MODE_ENCODER_TVDAC, "TVDAC" }, 75 { DRM_MODE_ENCODER_VIRTUAL, "Virtual" }, 76 { DRM_MODE_ENCODER_DSI, "DSI" }, 77 { DRM_MODE_ENCODER_DPMST, "DPMST" }, 78 { DRM_MODE_ENCODER_DPI, "DPI" }, 79}; 80 81const char *util_lookup_encoder_type_name(unsigned int type) 82{ 83 return util_lookup_type_name(type, encoder_type_names, 84 ARRAY_SIZE(encoder_type_names)); 85} 86 87static const struct type_name connector_status_names[] = { 88 { DRM_MODE_CONNECTED, "connected" }, 89 { DRM_MODE_DISCONNECTED, "disconnected" }, 90 { DRM_MODE_UNKNOWNCONNECTION, "unknown" }, 91}; 92 93const char *util_lookup_connector_status_name(unsigned int status) 94{ 95 return util_lookup_type_name(status, connector_status_names, 96 ARRAY_SIZE(connector_status_names)); 97} 98 99static const struct type_name connector_type_names[] = { 100 { DRM_MODE_CONNECTOR_Unknown, "unknown" }, 101 { DRM_MODE_CONNECTOR_VGA, "VGA" }, 102 { DRM_MODE_CONNECTOR_DVII, "DVI-I" }, 103 { DRM_MODE_CONNECTOR_DVID, "DVI-D" }, 104 { DRM_MODE_CONNECTOR_DVIA, "DVI-A" }, 105 { DRM_MODE_CONNECTOR_Composite, "composite" }, 106 { DRM_MODE_CONNECTOR_SVIDEO, "s-video" }, 107 { DRM_MODE_CONNECTOR_LVDS, "LVDS" }, 108 { DRM_MODE_CONNECTOR_Component, "component" }, 109 { DRM_MODE_CONNECTOR_9PinDIN, "9-pin DIN" }, 110 { DRM_MODE_CONNECTOR_DisplayPort, "DP" }, 111 { DRM_MODE_CONNECTOR_HDMIA, "HDMI-A" }, 112 { DRM_MODE_CONNECTOR_HDMIB, "HDMI-B" }, 113 { DRM_MODE_CONNECTOR_TV, "TV" }, 114 { DRM_MODE_CONNECTOR_eDP, "eDP" }, 115 { DRM_MODE_CONNECTOR_VIRTUAL, "Virtual" }, 116 { DRM_MODE_CONNECTOR_DSI, "DSI" }, 117 { DRM_MODE_CONNECTOR_DPI, "DPI" }, 118}; 119 120const char *util_lookup_connector_type_name(unsigned int type) 121{ 122 return util_lookup_type_name(type, connector_type_names, 123 ARRAY_SIZE(connector_type_names)); 124} 125 126static const char * const modules[] = { 127 "i915", 128 "amdgpu", 129 "radeon", 130 "nouveau", 131 "vmwgfx", 132 "omapdrm", 133 "exynos", 134 "tilcdc", 135 "msm", 136 "sti", 137 "tegra", 138 "imx-drm", 139 "rockchip", 140 "atmel-hlcdc", 141 "fsl-dcu-drm", 142 "vc4", 143 "virtio_gpu", 144 "mediatek", 145 "meson", 146 "pl111", 147 "stm", 148 "sun4i-drm", 149 "armada-drm", 150 "komeda", 151 "imx-dcss", 152 "mxsfb-drm", 153}; 154 155int util_open(const char *device, const char *module) 156{ 157 int fd; 158 159 if (module) { 160 fd = drmOpen(module, device); 161 if (fd < 0) { 162 fprintf(stderr, "failed to open device '%s': %s\n", 163 module, strerror(errno)); 164 return -errno; 165 } 166 } else { 167 unsigned int i; 168 169 for (i = 0; i < ARRAY_SIZE(modules); i++) { 170 printf("trying to open device '%s'...", modules[i]); 171 172 fd = drmOpen(modules[i], device); 173 if (fd < 0) { 174 printf("failed\n"); 175 } else { 176 printf("done\n"); 177 break; 178 } 179 } 180 181 if (fd < 0) { 182 fprintf(stderr, "no device found\n"); 183 return -ENODEV; 184 } 185 } 186 187 return fd; 188} 189
