Symptoms:
	PHKL_29425:
	( SR:8606314986 CR:JAGae77728 )
	Hardware Enablement: This product update enables perfmon
	support for the Intel(r) Itanium(r) 2 processors 1.3 GHz
	with 3M L3 cache.

	Systems using the 1.3GHz replacement processors for the
	Intel(r) Erratum 60 issue will see the message:

	  "PERFMON: Unrecognized processor model!"

	during boot or by running "dmesg | grep PERFMON".

	Applications using Perfmon, such as Caliper will not
	function properly without this product update.

Defect Description:
	PHKL_29425:
	( SR:8606314986 CR:JAGae77728 )
	This product update contains minor enhancements required
	to allow Perfmon to support for Intel(r) Itanium(r) 2
	processors with 3M L3 cache.

	This processor has a different model number -1- than the
	Intel(r) Itanium(r) 2 processor 1.0 GHz with 3M L3 cache
	-0-, and therefore is not recognised by the Perfmon
	subsystem. The CPU model number can be checked by running
	machinfo on Itanium(r) systems.

	The Perfmon kernel subsystem provides access to the
	processor's Performance Monitoring Unit (PMU), which is
	used by tools doing hardware perfmormance monitoring, such
	as Caliper.
	Since the PMU may change from model to model, Perfmon will
	not initialize if it does not have the CPU model in its
	database.

	Resolution:
	Update the Kernel Registry Database (KRS) to add definitions
	for newer Intel(r) Itanium(r) 2 processors, including the
	Intel Itanium(r) 2 1.3 GHz processor with 3M L3 cache.
	This product update will have no impact if applied on
	systems that do not have the newer processor models.

	Caliper users will also need to upgrade to version 3.1 or
	later, as the application also has to be aware of the
	processor model and OS version.

Enhancement:
	No

	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHKL_29425

	5. Run swinstall to install the patch:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -s /tmp/PHKL_29425.depot

	By default swinstall will archive the original software in 
	/var/adm/sw/save/PHKL_29425.  If you do not wish to retain a
	copy of the original software, include the patch_save_files
	option in the swinstall command above:

		-x patch_save_files=false

	WARNING: If patch_save_files is false when a patch is installed,
		 the patch cannot be deinstalled.  Please be careful
		 when using this feature.

	For future reference, the contents of the PHKL_29425.text file is 
	available in the product readme:

		swlist -l product -a readme -d @ /tmp/PHKL_29425.depot

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHKL_29425.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	PHKL_29425 cannot be installed during a cold-install
	session.  If included in a cold-install depot, it will be
	excluded from installation and a notice will be printed in
	the log file.  PHKL_29425 may be installed after the
	operating system has been installed.
