Support for Monticeto and Arches Intel is making changes for Montecito, and HP may have additional changes once we learn more about this new CPU (e.g. enhancements to MCA handling). At this time, we are not aware of any changes required, beyond the changes that Intel has already submitted into kernel.org (support for new instructions in Montecito). Also, there *may* need to be changes to the toolchain (gcc, assembler, etc.) to accomodate the new instructions. HP LOSL has just started an investgiation of Arches, and we will have more detail by January 2004 on the impact to Linux to support Arches. At this time we know that we will need to provide support for HPET and async clocks - we are currently working on this and the code will go into 2.6.
Montecito is Intel's dual-core, dual- and multiprocessor follow-on to the Madison 9n processor. Due early 2005. Has larger caches than Madison, plus 9nm technologies.
Conditionally accept if patches are upstream by May (A2).
HP will provide patches upstream for Arches by April 1; hardware as well (Montecito and Arches) by April 1.
SUBMIT_UPSTREAM for the code part, leaving open as NEEDINFO due to the requirement for hardware.
HP-IPF is currently evaluating schema to see whether any o/s changes need to be submitted upstream; to date, none is identified. Hardware (functional prototypes) (Montecito is the processor; Arches is the I/O chipset) now scheduled to be available to RH in April. Production protos to RH by early June; final systems to RH by August. (They'll replace the functional and production protos when final production systems out.)
*** Bug 108806 has been marked as a duplicate of this bug. ***
Update to this: Charline checking dates on when functional prototypes will be available. Was supposed to be April.

Including support for HPET > and async clocks Yes, on Arches support (that we know of to-date) No on HPET. Code complete, but waiting on Intel to validate ia32 issues before going into 2.6. HP would still like to get this into RHEL 4. HARDWARE DEADLINE was 4/01. Per above, Charline checking dates on when functional prototypes will be available.
Wasn't specified in time. Won't commit to do this for RHEL4. They have missed the deadline for RHEL4. Systems may work with RHEL4, but we can't guarantee it at this point, nor will it be a fully-supported configuration.
Splitting this out into two FZ's. * Arches hardware won't be available until 2Q2005 so new FZ created with target RHEL4_U1. * Montecito support is in U1 and will be base RHEL4. (this FZ) - Leaving this CLOSED-DEFERRED in case any new Monticeto fucntion is being requested per comment #11 above.
Arches FZ is Bug 124923
Base Montecito support shipped in RHEL3 U1 and will be in the RHEL4 base. If HP identifies additional support based on Intel's Monticeto changes and provides hardware, RH will make a best effort to incorporate these changes into RHEL4. However, if there are significant kernel updates required, they will need to wait for RHEL4 U1.
PM ACK for U2.
