Here are two documents that contain updates on the items listed below, all
of which are added as requirements.

Reqmnts subgroup would know when the official doc is going to be updated,
but I think the deadline is mid-Sep.

Okay.  More questions.

Those first questions (below) came from mapping ABAT suites to requirements.
Now, I've tried to map all validation suites to requirements and came up
with a few more that don't map.  I've been told that these will be added to
the requirements document soon.  =


I was wondering if there was any update on:
- requirement numbers and
- requirement categories =

for these items as we'd need those in order to be able to create suites?

Here are the items:
92 - Enhanced locking primitives
93 - Locking primitives
94 - Remove kernel locks
95 - Counter scalability
97 - Kernel debug security
98 - Hyperthreading (discussed below)
99 - Multithreaded core dump

Thanks.

Panic handler enhancements is Req 3.11. Hyperthreading was recently included
as a requirement - not sure if there is a number assigned yet.

Ownership for item 79 and 99 was discussed in the release coordination
meeting yesterday. Validatinon chair has the AR to try and sign up
maintainers for these by 9/16.

I'm hoping someone on this list can answer my questions.

I'm looking at the validation suites listed in milestone M3, and there were
two suites where I was unsure which requirement in the CGLE requirements
document they applied to.  Those suites were:

Item 82 - Panic Handler Enhancements
Item 98 - Hyper-threading support with Processor Affinity

Can anyone tell me which requirement number these suites are testing?

Also, I may have missed the discussion, but do we have validation suite
owners for:

Item 79 - Disk and Volume Management
Item 99 - Multithreaded core dump

Thanks.

"hardware and software" but requirements only hardware.  Align.
3.3 App HB -- Configurable 1.1 -- NOTE: The
specification has not been widely viewed and accepted in the kernel or
other communities, therefore its eventual acceptance is unknown.
(Change from: Proposed to Core 2.0, awaiting status of spec (not yet
publicised for community review) and final decision.  Seems if we can
get specification (on which code is based) to where we believe it
would be accepted can keep code.)
3.4.1 Bonding aggregate -- Configurable 1.1
3.4.2 Bonding failover -- Configurable 1.1
3.5.1 RAID 1 -- Configurable 1.1
3.6 Resilient filesystem -- Configurable 1.1
3.7 Disk and Volume management -- Configurable 1.1
4.1.1 Resource monitor specification -- Configurable 1.1 -- NOTE:
The specification has not been widely viewed and accepted in the
kernel or other communities, therefore its eventual acceptance is
unknown.  Therefore, make all related items Configurable to match.
4.1.2 Resource monitor framework -- Configurable 1.1
4.1.3 Resource monitor subsystem -- Configurable 1.1

4.2.1 Kernel dump targets -- Core 1.1
4.2.2 Kernel summary dump -- Core 1.1
4.3 Kernel message structuring -- Configurable 1.1 -- NOTE: There is
not yet an accepted way to do this that has been widely viewed and
accepted in the kernel or other communities, therefore its eventual

4.4 Dynamic debug probe insertion -- Configurable 1.1 -- NOTE: This
project is widely known across the community, but is not accepted as a
base item as yet.

2.7 Alternate  boot selection (automatic) -- Core 2.0
3.2.2 Watchdog timer pre-timeout -- Core 2.0
3.8.1 Software live upgrade minimal reboot -- Configurable 2.0 --
NOTE: This is an item that we should define standards, behaviors,
expectations, and push to have a distribution-independent method.
However, current distributions use this to help differentiate and we
should continue to not preclude that so long as they meet some
standards.  Whichever method is chosen though must provide all of
these features as listed here, Configurable doesn't mean that they can
leave some off.
3.8.2 Software live upgrade version check -- Configurable 2.0
3.8.3 Software live upgrade log -- Configurable 2.0
3.8.4 Software live upgrade rollback -- Configurable 2.0
4.7 Fast boot time enabling -- Configurable 1.1 -- NOTE: how does this
compare with the 'fast reboot' item (see below) we just voted in?
4.8.1 System device enumeration framework -- Core 2.0 -- NOTE:  Wrong
order, specification first, then framework.  In any case, nothing has
been exposed to community, well, depends on how you count devfs and
such work.

4.9.3 Diagnostics support through CIM, CIMOM -- Configurable 2.0
4.10 Force unmount -- Core 2.0

5.4.2 Fault injection framework -- Configurable 2.0
5.4.3 Fault injection points -- Configurable 2.0
5.5.1 Kernel flat graph execution profile -- Configurable 2.0 --
NOTE: Could be Configurable 1.1 but no work on pulling in any of the
relevant projects.
5.5.2 Kernel sampling capability -- Configurable 2.0
5.6 System tools to analyze execution profiles -- Configurable 2.0
6.1.2 Concurrent thread scaling analysis -- NA

other communities, therefore its eventual acceptance is unknown.
6.8 Page flushing -- Configurable 2.0 -- NOTE: The
specification has not been widely viewed and accepted in the kernel or =

other communities, therefore its eventual acceptance is unknown.
6.9 Process affinity -- Core 2.0 -- NOTE:  Support is in the kernel
for this and a method/API exists, but we haven't identified it to be
pulled in yet.
6.10 Selectable scheduler policies -- Configurable 1.1
1.9 Service Availability Forum standards -- Configurable 2.0 -- NOTE:
The specification has not been widely viewed and accepted in the
kernel or other communities, therefore its eventual acceptance is
unknown. =

3.11 Multi-node volume management -- Configurable 2.0
3.12 Cluster filesystem -- Configurable 2.0

OSDL CGL-WG Requirements subgroup minutes - 6 Sept 2002

Attendees: Peter Badovinatz, John Cherry, Mika Kukkonen, Karl
Klashinsky, Stephanie Glass, Randy Dunlap, Stephano Campadello,
Ibrahim Haddad, Andy Cress, Pradeep Kathail

Pradeep registered his opposition and annoyance at the hyperthreading
requirement.  I (Peter) described that the proposal to add it had been
posted, discussed and accepted, minutes had been posted documenting
the whole process.  As the subgroup has accepted it, he agreed to
leave it at that.  [Summary of a number of minutes of discussion, and
no, he did not agree that easily :o).]

AR: For all, ensure that we crispen the processes to bring new and
changed items to documents.

Craig suggested that the 'justifications' for why Requirements are NOT
considered 'CORE 1.1' be included when I update the Requirements
document.

AR: Peter - accepted, will do.

Rest of call was spent going through the list of Requirements to
discuss my assignment of them using Core, Configurable, External, to
1.1, 2.0 or 3.0.  This list is being used to update the Requirements
document, which will be posted to php before 8:00 AM, Monday, 9
September, EUROPEAN time.

Monday's phone call will be (mostly) Architecture, going over the
updates.

AR: Get updates to John C. (I am one of the chosen.)

List: (also posted as 'core_config_UPDATE.txt')
UPDATE_0906: I have updated each item with the results of the 6
September Requirements call.  This is quicker for verification and the
info will be captured in the 1.1 Document.

Items in the 1.0 Requirements document.  Analyze them using the 'new'
Core, Configurable, External descriptions.  Moot this through the
group and then update the requirements document.

These items are in same order as they are in the Requirements 1.0
specification.
