By IEEE 1275 compatibility conventions, 14237c478bd9Sstevel@tonic-gate * 8514/A registers should have been added after all standard VGA registers. 14247c478bd9Sstevel@tonic-gate * Unfortunately, the Solaris/Intel device configuration framework 14257c478bd9Sstevel@tonic-gate * (a) lists the 8514/A registers before the video memory, and then 14267c478bd9Sstevel@tonic-gate * (b) also sorts the entries so that I/O entries come before memory 14277c478bd9Sstevel@tonic-gate * entries. 14287c478bd9Sstevel@tonic-gate * 14297c478bd9Sstevel@tonic-gate * It returns the "reg" index and offset into that register set. 14307c478bd9Sstevel@tonic-gate * The offset is needed because there exist (broken?) BIOSes that 14317c478bd9Sstevel@tonic-gate * report larger ranges enclosing the standard ranges. One reports 14327c478bd9Sstevel@tonic-gate * 0x3bf for 0x21 instead of 0x3c0 for 0x20, for instance. Using the 14337c478bd9Sstevel@tonic-gate * offset adjusts for this difference in the base of the register set. 14347c478bd9Sstevel@tonic-gate * 14357c478bd9Sstevel@tonic-gate * Note that this routine may not be fully general; it is intended for the 14367c478bd9Sstevel@tonic-gate * specific purpose of finding a couple of particular VGA reg entries and 14377c478bd9Sstevel@tonic-gate * may not be suitable for all reg-searching purposes. 14387c478bd9Sstevel@tonic-gate */ 14397c478bd9Sstevel@tonic-gate static int 14407c478bd9Sstevel@tonic-gate vgatext_get_isa_reg_index( 14417c478bd9Sstevel@tonic-gate dev_info_t *const devi, 14427c478bd9Sstevel@tonic-gate unsigned long hival, 14437c478bd9Sstevel@tonic-gate unsigned long addr, 14447c478bd9Sstevel@tonic-gate off_t *offset) 14457c478bd9Sstevel@tonic-gate { 14467c478bd9Sstevel@tonic-gate 14477c478bd9Sstevel@tonic-gate int length, index; 14487c478bd9Sstevel@tonic-gate struct regspec *reg; 14497c478bd9Sstevel@tonic-gate 14507c478bd9Sstevel@tonic-gate if (ddi_getlongprop(DDI_DEV_T_ANY, devi, DDI_PROP_DONTPASS, 14517c478bd9Sstevel@tonic-gate "reg", (caddr_t)®, &length) != DDI_PROP_SUCCESS) { 14527c478bd9Sstevel@tonic-gate return (-1); 14537c478bd9Sstevel@tonic-gate } 14547c478bd9Sstevel@tonic-gate 14557c478bd9Sstevel@tonic-gate for (index = 0; index < length / sizeof (struct regspec); index++) { 14567c478bd9Sstevel@tonic-gate if (reg[index].regspec_bustype != hival) 14577c478bd9Sstevel@tonic-gate continue; 14587c478bd9Sstevel@tonic-gate if (reg[index].regspec_addr > addr) 14597c478bd9Sstevel@tonic-gate continue; 14607c478bd9Sstevel@tonic-gate if (reg[index].regspec_addr + reg[index].regspec_size <= addr) 14617c478bd9Sstevel@tonic-gate continue; 14627c478bd9Sstevel@tonic-gate 14637c478bd9Sstevel@tonic-gate *offset = addr - reg[index].regspec_addr; 14647c478bd9Sstevel@tonic-gate kmem_free(reg, (size_t)length); 14657c478bd9Sstevel@tonic-gate return (index); 14667c478bd9Sstevel@tonic-gate } 14677c478bd9Sstevel@tonic-gate kmem_free(reg, (size_t)length); 14687c478bd9Sstevel@tonic-gate 14697c478bd9Sstevel@tonic-gate return (-1); 14707c478bd9Sstevel@tonic-gate } 1471
