PSARC 1994/188	PowerPC Base Kernel		Prasad Singamsetty 

-----------------------------------------------------------------------------

1.  What specifically is the proposal that we are reviewing?  

    This project is the Base Kernel for Solaris port to PowerPC platform.

    Please refer to the section 2 of the 1pager and section 4 of
    project plan (for OSSC review) for deliverables.

    The attachments (appendices) that has additional information on the
    project are:

	kern.1pager		One Pager for this project.

	kern.project_plan	Project plan that was presented for OSSC
				review.

	kern.issues		File that briefly describes the issues that
				need to be addressed by PSARC.

	kern.common.changes	File that lists the common files that were
				affected for this project and the diff outputs
				on these files.

	kern.project.files	File that lists all the base kernel files
				that are specific to PowerPC and the nature
				of work done on these files. Also lists the
				kernel binary modules that are part of the
				base kernel.

2.  What is the motivation for it? 

    Please see the section 5 of the 1pager and section 3.1 of the
    project plan.

3.  What is its plan?

    Please refer to the project plan for details.

- What is its current status?

    The system is being integrated/tested for an EA release.

- Has a design review been done?

    Major areas of design review was done with the respective groups.
    VM/HAT design was reviewed by VM group, Locking primitives
    for PPC was reviewed by Joe Eykholt and the rest of the areas
    which use existing interfaces/design may be considered for review.

4.  Are there related projects in Sun?  

    Yes, there are three other projects that are closely related to this.

	Solaris Header Files for PowerPC  (PSARC 1994/196)
	Solaris Commands for PowerPC	  (PSARC 1994/197)
	Solaris Libraries for PowerPC	  (PSARC 1994/198)

    Other projects that are of interest to this project:

	Solaris FUSION project (VM/HAT interface component).

5.  What is the technical content of the project? Please provide diagrams that 
    make the project's interfaces clear.

    Please refer to sections 2.1 and 7.3 of the project plan.

6.  How is the project delivered into the system?  Identify packages, 
    directories, libraries, databases, ...?

    This project leads towards a full set of PowerPC packages built by the ON
    Consolidation.

7.  What are the project's hardware platform dependencies?  Is it expected to 
    work on SPARC and Intel (and PowerPC)?  What will be affected in porting?

    This is part of the Solaris port to PowerPC platform and it should not
    have any effect on Sparc and Intel.

12.  What are its other significant internal interfaces (inter-subsystem and 
     inter-invocation)?

    N/A.

13. How do the interfaces deal with applicable standards?

    N/A.

14. Is the interface extensible?  How is the interface expected to evolve? 

    N/A.

15. How do the interfaces adapt to a changing world?

    N/A.

16. What internationalization issues are involved? (if strings are used, how 
    are they accessed?

   None.

17. How will the project contribute (positively or negatively) to "system load" 
    and "perceived performance":						

   N/A.

18. How does the project deal with failure and recovery?

   N/A.

19. Issues? Please identify the issues which you would like the ARC to address.

    Issues:	Kernel module linking.
		Console support.
		Promif support.
		Platform Specific Module (PSM) support.

	  proposed classifications.
	- One-Pager.
	- Prototype specification.
	- References to other documents (copies to be places in case directory).
