Jung-uk Kim 3219f535d9 Rewrite x86bios and update its dependent drivers. ... - Do not map entire real mode memory (1MB). Instead, we map IVT/BDA and ROM area separately. Most notably, ROM area is mapped as device memory (uncacheable) as it should be. User memory is dynamically allocated and free'ed with contigmalloc(9) and contigfree(9). Remove now redundant and potentially dangerous x86bios_alloc.c. If this emulator ever grows to support non-PC hardware, we may implement it with rman(9) later. - Move all host-specific initializations from x86emu_util.c to x86bios.c and remove now unnecessary x86emu_util.c. Currently, non-PC hardware is not supported. We may use bus_space(9) later when the KPI is fixed. - Replace all bzero() calls for emulated registers with more obviously named x86bios_init_regs(). This function also initializes DS and SS properly. - Add x86bios_get_intr(). This function checks if the interrupt vector is available for the platform. It is not necessary for PC-compatible hardware but it may be needed later. ;-) - Do not try turning off monitor if DPMS does not support the state. - Allocate stable memory for VESA OEM strings instead of just holding pointers to them. They may or may not be accessible always. Fix a memory leak of video mode table while I am here. - Add (experimental) BIOS POST call for vesa(4). This function calls VGA BIOS POST code from the current VGA option ROM. Some video controllers cannot save and restore the state properly even if it is claimed to be supported. Usually the symptom is blank display after resuming from suspend state. If the video mode does not match the previous mode after restoring, we try BIOS POST and force the known good initial state. Some magic was taken from NetBSD (and it was taken from vbetool, I believe.) - Add a loader tunable for vgapci(4) to give a hint to dpms(4) and vesa(4) to identify who owns the VESA BIOS. This is very useful for multi-display adapter setup. By default, the POST video controller is automatically probed and the tunable "hw.pci.default_vgapci_unit" is set to corresponding vgapci unit number. You may override it from loader but it is very unlikely to be necessary. Unfortunately only AGP/PCI/PCI-E controllers can be matched because ISA controller does not have necessary device IDs. - Fix a long standing bug in state save/restore function. The state buffer pointer should be ES:BX, not ES:DI according to VBE 3.0. If it ever worked, that's because BX was always zero. :-) - Clean up register initializations more clearer per VBE 3.0. - Fix a lot of style issues with vesa(4).		2009-10-19 20:58:10 +00:00
