Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S. Habibulin (Blade 100 w/ on-board Rage XL)

Make sparc64 compatible with NEW_PCIB and enable it: - 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 machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4).

- Declare lookup tables etc. const. [1] - Add a missing "ATI" in one of the device descriptions. - In machfb_init_engine() adjust a wait_for_fifo() call to the actual number of operations. - As a speed optimization cache setting the foreground and back- ground colors. - I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn off and not blank like turn on and clear the screen. So move clearing the screen to machfb_clear() were it hopefully belongs. - Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko work. [1] - Implement machfb_load_palette() and machfb_save_palette() and set the V_ADP_PALETTE flag. This makes fade_saver.ko work. [2] - Install our 16-color color map only once and with an offset of 16 as the OBP driver expects white to be at index 0 and black at 255. This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down. This hopefully will fix the screen corruption happening occasionally when shutting down the X server and which is present until switching to another VTY.

[2] - Install our 16-color color map only once and with an offset of 16 as the OBP driver expects white to be at index 0 and black at 255. This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down.

[1] - Add a missing "ATI" in one of the device descriptions. - In machfb_init_engine() adjust a wait_for_fifo() call to the actual number of operations. - As a speed optimization cache setting the foreground and back- ground colors. - I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn off and not blank like turn on and clear the screen. So move clearing the screen to machfb_clear() were it hopefully belongs. - Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko work. [1] - Implement machfb_load_palette() and machfb_save_palette() and set the V_ADP_PALETTE flag. This makes fade_saver.ko work. [2] - Install our 16-color color map only once and with an offset of 16 as the OBP driver expects white to be at index 0 and black at 255. This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down. This hopefully will fix the screen corruption happening occasionally when shutting down the X server and which is present until switching to another VTY.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S.

This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down. This hopefully will fix the screen corruption happening occasionally when shutting down the X server and which is present until switching to another VTY.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4).

In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4).

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products.

Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S.

- Declare lookup tables etc. const. [1] - Add a missing "ATI" in one of the device descriptions. - In machfb_init_engine() adjust a wait_for_fifo() call to the actual number of operations. - As a speed optimization cache setting the foreground and back- ground colors. - I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn off and not blank like turn on and clear the screen. So move clearing the screen to machfb_clear() were it hopefully belongs. - Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko work. [1] - Implement machfb_load_palette() and machfb_save_palette() and set the V_ADP_PALETTE flag. This makes fade_saver.ko work. [2] - Install our 16-color color map only once and with an offset of 16 as the OBP driver expects white to be at index 0 and black at 255. This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down. This hopefully will fix the screen corruption happening occasionally when shutting down the X server and which is present until switching to another VTY.

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S.

The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast.

In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port).

Make sparc64 compatible with NEW_PCIB and enable it: - 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 machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64.

Make sparc64 compatible with NEW_PCIB and enable it: - 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 machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips. Depending on the version of the OBP Mach64 cards destined for use in i386 machines also work in sun4u machines. The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP.

- Declare lookup tables etc. const. [1] - Add a missing "ATI" in one of the device descriptions. - In machfb_init_engine() adjust a wait_for_fifo() call to the actual number of operations. - As a speed optimization cache setting the foreground and back- ground colors. - I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn off and not blank like turn on and clear the screen. So move clearing the screen to machfb_clear() were it hopefully belongs. - Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko work. [1] - Implement machfb_load_palette() and machfb_save_palette() and set the V_ADP_PALETTE flag. This makes fade_saver.ko work. [2] - Install our 16-color color map only once and with an offset of 16 as the OBP driver expects white to be at index 0 and black at 255. This fixes the inversion of the colors back at the boot prompt after shutting down FreeBSD. This will also be handy if we ever want to implement breaking into OFW. Unfortunately there doesn't seem to be a better way to achieve this as e.g. bypassing the color map isn't supported by all Mach64 chips. - Move invalidating the cache variables to machfb_set_mode() and set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to be called when the X server shuts down. This hopefully will fix the screen corruption happening occasionally when shutting down the X server and which is present until switching to another VTY.

The driver uses pixel mode with hardware acceleration as far as syscons(4) currently permits on sparc64 so text mode is already quite fast. The hardware cursor is used for the mouse pointer; for one because this is a "restriction" induced in syscons(4) on sparc64 by creator(4) and also because of issues with mapping the aperture when used as a low-level early during boot. Due to insufficiencies in the available documentation I didn't manage to get mode switch work properly (sync problems), yet. So for now this driver relies on the OBP having initialised a mode (as does creator(4)). On all of the tested machines is even true when using a serial console (and also not only when the OBP switched to a serial console because no keyboard is present). In general however the states the Mach64 chips are left in by the OBP vary a lot depending on the version of the OBP. This e.g. includes the aperture not being mapped in even when used as the console and the OBP just barfing when asked to map it. The latter is also the reason for the existence of this native driver in FreeBSD rather than taking an OFW frambuffer approach. Xorg is also happy to talk to these chips by mmap'ing them through this driver. For some hardware configs like on the Blade 100 a fix for the Xorg sparc64 MD bus code is however needed (added in version 6.8.2_2 of the xorg-server port). The video driver font loading and saving methods are not implemented, yet, as syscons(4) needs more work in that area to work viable on sparc64. With minor modifications machfb(4) would most likely also work on powerpc, when #ifdef'ing the OFW and possibly implementing mode setting probably also on the other archs. The latter is however not very practible at the moment as it would conflict with vga(4). Tested/developed with: Rage II+ add-on card on AX1105 and AXi board, AXe board (on-board Rage Pro) Additional testing by: marcel (Ultra 5 w/ on-board Rage Pro), scottl (Naturetech GENIALstation 777S w/ on-board Rage Mobility M1), Michiel Boland and Ilmar S. Habibulin (Blade 100 w/ on-board Rage XL)

Add machfb(4), a driver for ATI Mach64 graphics chips intended for use with syscons(4) on sparc64. It's based on the respective NetBSD driver with some additional info (initialisation/hardware cursor) obtained from the Xorg 'ati' driver and some ideas taken from creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low- end graphics chips in PCI-based sun4u machines and are used on-board in e.g. Blade 100 and a couple of OEM products. Most if not all of the Sun PGX add-on cards family (descriptions of the PGX32 are conflicting but most say it's a Rage Pro) are also based on these chips.
