The Full Form of LKP is Linux Kernel Personality.

No special action is required to install the LKP kernel components; they are installed automatically by the UpdateSet during a fresh or update installation of Open UNIX 8.

The remainder of the LKP product on the Updates CD-ROM, and the additional Linux RPM CD-ROM, should be installed following the instructions found in the LKP Release Notes (relnotes_lkp), under the /info on either the Base Operating System CD-ROM (CD1) or the Updates CD-ROM (CD2).

Note that you’ll need at least 1.8GB disk space on your root disk to install LKP and all the packages on the Linux RPM CD-ROM.

LKP documentation is available in the lkpdoc package on the Updates CD-ROM. This package can be installed by inserting the Updates CD-ROM and entering:

   pkgadd -d cdrom1 lkpdoc

Once installed, the LKP documentation is found under the Linux Kernel Personality topic.

       Linux supports different execution domains, or personalities, for
       each process.  Among other things, execution domains tell Linux how
       to map signal numbers into signal actions.  The execution domain
       system allows Linux to provide limited support for binaries compiled
       under other UNIX-like operating systems.

       If persona is not 0xffffffff, then personality() sets the caller's
       execution domain to the value specified by persona.  Specifying
       persona as 0xffffffff provides a way of retrieving the current
       persona without changing it.
