Machine Access
--------------
Projects modifying their code impacting sun4u platforms also need to
test their code on an OPL platform. To get access to an OPL system,
please send email including the following subject as:
To : opl_hw_access at sun dot com
Subject: Need OPL Jupiter System Access
Upgrade Instruction for existing OPL systems
--------------------------------------------
Note that OPL Jupiter CPU is in limited quantity. Please
contact OPL Jupiter Software team for access and complete
installation/upgrade instruction.
OPL Jupiter CPU support requires upgrade of the following
software components prior to installing new Jupiter CPU
module.
- XSCF Software, includes
- Service Processor Software
- POST
- OBP
- Solaris with OPL Jupiter CPU support
OPL Jupiter Rev A chip not supported
-------------------------------------
Current revision of Jupiter Rev A CPU have bugs
that require low level (DDI and assembly level)
workarounds. These workarounds will not be putback
to Solaris.
Jupiter Rev B CPUs will be supported once they are
available towards the end of the year.
There are very few quantity of Jupiter Rev A CPU
available today and they will be phased out when
the Rev B CPUs arrive.
Teams that use Jupiter Rev A CPU should contact
Jupiter Software team for access of special Jupiter
development software with Rev A CPU support.
Bug Filing
