After consulting with the SMF team, I have updated the case write-up to
reflect the following changes:
1. Project name has been changed to
Introducing non-persistent property group config_ovr.
2. Boolean type property config_ovr/fastreboot_default will be used.
3. The library interface will be called
scf_fastreboot_default_set_transiet()
The updated write-up has been copied to the materials directory.
Thanks,
Sherry

Introducing non-persistent property group config_ovr.

1.3.1. Date this project was conceived:

2. Project Summary
2.1. Project Description:
To provide an override mechanism to disable Fast Reboot for the
next reboot only.
4. Technical Description:
4.1. Details:
With the putback of Fast Reboot by Default (PSARC 2008/760,
2009/091 and 2009/092), a Fast Reboot capable system will
bypass firmware when "reboot" or "init 6" is invoked. For
those users who wish to reboot through firmware, they can
invoke "reboot -p" directly, or set config/fastreboot_default
to false, then reboot.
However, there are cases where a user would like to reboot
through firmware only for the next reboot. One of such case is
to fully reset the hardware based on vendor recommendation for
newly flashed firmware to take effect on the Hermon cards.
While "reboot -p" should suffice, it's preferable if user
doesn't have to type the additional "-p" option directly.
Another usage model is the "Restart" button from the "Shutdown"
menu in GNOME desktop, which currently invokes "init 6". A new
"Restart through PROM" button could be added to perform the
equivalent of "reboot -p", but with all the clean shutdown
currently performed by "init 6".
To enable the above usage models, a new non-persistent property
group "config_ovr" will be introduced to
svc:/system/boot-config:default. The only supported property
in the "config_ovr" property group is "fastreboot_default".
The setting of "config_ovr/fastreboot_default" takes
precendence over "config/fastreboot_default".

4.6. Doc Impact:
4.6.1 Man pages for scf_fastreboot_default_set_transient(3LIB)
int scf_fastreboot_default_set_transient(boolean_t val); |
|
The scf_fastreboot_default_set_transient() function sets |
the config_ovr/fastreboot_default property in |
svc:/system/boot-config:default to the passed in value, |
which overrides the setting of config/fastreboot_default. |
If it's FALSE, the next reboot will go through firmware; |
if it's TRUE, the next reboot will bypass firmware. |
