Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily.

* Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.Ed Schouten2011-11-071-1/+1
| | | | | | | | | The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static. Notes: svn path=/head/; revision=227309
* Make sparc64 compatible with NEW_PCIB and enable it:Marius Strobl2011-10-021-55/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Implement bus_adjust_resource() methods as far as necessary and in non-PCI bridge drivers as far as feasible without rototilling them. - As NEW_PCIB does a layering violation by activating resources at layers above pci(4) without previously bubbling up their allocation there, move the assignment of bus tags and handles from the bus_alloc_resource() to the bus_activate_resource() methods like at least the other NEW_PCIB enabled architectures do. This is somewhat unfortunate as previously sparc64 (ab)used resource activation to indicate whether SYS_RES_MEMORY resources should be mapped into KVA, which is only necessary if their going to be accessed via the pointer returned from rman_get_virtual() but not for bus_space(9) as the later always uses physical access on sparc64. Besides wasting KVA if we always map in SYS_RES_MEMORY resources, a driver also may deliberately not map them in if the firmware already has done so, possibly in a special way. So in order to still allow a driver to decide whether a SYS_RES_MEMORY resource should be mapped into KVA we let it indicate that by calling bus_space_map(9) with BUS_SPACE_MAP_LINEAR as actually documented in the bus_space(9) page. This is implemented by allocating a separate bus tag per SYS_RES_MEMORY resource and passing the resource via the previously unused bus tag cookie so we later on can call rman_set_virtual() in sparc64_bus_mem_map(). As a side effect this now also allows to actually indicate that a SYS_RES_MEMORY resource should be mapped in as cacheable and/or read-only via BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_READONLY respectively. - Do some minor cleanup like taking advantage of rman_init_from_resource(), factor out the common part of bus tag allocation into a newly added sparc64_alloc_bus_tag(), hook up some missing newbus methods and replace some homegrown versions with the generic counterparts etc. - While at it, let apb_attach() (which can't use the generic NEW_PCIB code as APB bridges just don't have the base and limit registers implemented) regarding the config space registers cached in pcib_softc and the SYSCTL reporting nodes set up.

* Add an experimental feature to shadow video BIOS. Long ago, this trick wasJung-uk Kim2010-08-251-10/+57
| | | | | | | | | | | | | supported by many BIOSes to improve performance of VESA BIOS calls for real mode OSes but it is not our intention here. However, this may help some platforms where the video ROMs are inaccessible after suspend, for example. Note it may consume up to 64K bytes of contiguous memory depending on video controller model when it is enabled. This feature can be disabled by setting zero to 'debug.vesa.shadow_rom' loader tunable via loader(8) or loader.conf(5). The default is 1 (enabled), for now. Notes: svn path=/head/; revision=211827

Now we don't have to set `hint.sc.0.vesa_mode' to get the default palette data. - Add a new adapter flag, V_ADP_DAC8 to track whether the controller is using 8-bit palette format and load correct palette when switching modes. - Set 8-bit DAC mode only for non-VGA compatible graphics mode.

* Fix VESA color palette corruption:Jung-uk Kim2009-11-031-59/+36
| | | | | | | | | | | | | | | - VBE 3.0 says palette format resets to 6-bit mode when video mode changes. We simply set 8-bit mode when we switch modes if the adapter supports it. - VBE 3.0 also says if the mode is not VGA compatible, we must use VBE function to save/restore palette. Otherwise, VGA function may be used. Thus, reinstate the save/load palette functions only for non-VGA compatible modes regardless of its palette format. - Let vesa(4) set VESA modes even if vga(4) claims to support it. - Reset default palette if VESA pixel mode is set initially. - Fix more style nits.

| | | | | | | | | | | | | | | | function may not work properly if we don't. Turn off hardware cursor as vesa_set_mode() does. - Add VBE 3.0 specific fields in VESA mode structure and pack it. Note the padding is 190 bytes although VBE 3.0 says 189 bytes. It must be wrong because the size of structure becomes 255 bytes and the specification says it must be 256 bytes in total. In fact, an example code in the spec. does it right, though. While we are at it, fix some i386-isms. - Remove state buffer size limitation. It is no longer necessary since sys/compat/x86bios/x86bios.c r198251. - Move int 0x10 vector test into vesa_bios_post() as we always do it anyway. Notes: svn path=/head/; revision=198419
* Rewrite x86bios and update its dependent drivers.Jung-uk Kim2009-10-191-301/+487
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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).
