o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

- Use register macros instead of magic values in the code. [1]

than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us

- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the

Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]

o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which

o creator(4):
- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).
o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
- Attach syscons(4) as an own pseudo-device on the nexus rather than
directly in creator_upa_attach(), similiar to attaching syscons(4)
as a pseudo-device on isa(4) on other archs. This makes it a whole
lot easier to do the right thing in multi-head configs, especially
with different types of graphics adapters. [2]
- Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
box. [2]
