By IEEE 1275 compatibility conventions, 1266 * 8514/A registers should have been added after all standard VGA registers. 1267 * Unfortunately, the Solaris/Intel device configuration framework 1268 * (a) lists the 8514/A registers before the video memory, and then 1269 * (b) also sorts the entries so that I/O entries come before memory 1270 * entries. 1271 * 1272 * It returns the "reg" index and offset into that register set. 1273 * The offset is needed because there exist (broken?) BIOSes that 1274 * report larger ranges enclosing the standard ranges. One reports 1275 * 0x3bf for 0x21 instead of 0x3c0 for 0x20, for instance. Using the 1276 * offset adjusts for this difference in the base of the register set. 1277 * 1278 * Note that this routine may not be fully general; it is intended for the 1279 * specific purpose of finding a couple of particular VGA reg entries and 1280 * may not be suitable for all reg-searching purposes. 1281 */ 1282 static int 1283 vgatext_get_isa_reg_index( 1284 dev_info_t *const devi, 1285 unsigned long hival, 1286 unsigned long addr, 1287 off_t *offset) 1288 { 1289 1290 int length, index; 1291 struct regspec *reg; 1292 1293 if (ddi_getlongprop(DDI_DEV_T_ANY, devi, DDI_PROP_DONTPASS, 1294 "reg", (caddr_t)®, &length) != DDI_PROP_SUCCESS) { 1295 return (-1); 1296 } 1297 1298 for (index = 0; index < length / sizeof (struct regspec); index++) { 1299 if (reg[index].regspec_bustype != hival) 1300 continue; 1301 if (reg[index].regspec_addr > addr) 1302 continue; 1303 if (reg[index].regspec_addr + reg[index].regspec_size <= addr) 1304 continue; 1305 1306 *offset = addr - reg[index].regspec_addr; 1307 kmem_free(reg, (size_t)length); 1308 return (index); 1309 } 1310 kmem_free(reg, (size_t)length); 1311 1312 return (-1); 1313 } 1314 1315 /* 1316 * This vgatext function is used to return the fb, and reg pointers 1317 * and handles for peer graphics drivers. 1318 */ 1319 1320 void 1321 vgatext_return_pointers(struct gfxp_fb_softc *softc, struct vgaregmap *fbs, 1322 struct vgaregmap *regss) 1323 { 1324 1325 fbs->addr = softc->console->vga.fb.addr; 1326 fbs->handle = softc->console->vga.fb.handle; 1327 fbs->mapped = softc->console->vga.fb.mapped; 1328 regss->addr = softc->console->vga.regs.addr; 1329 regss->handle = softc->console->vga.regs.handle; 1330 regss->mapped = softc->console->vga.regs.mapped; 1331 } 1332
