Patrick,
I've only done a very quick search, but I found some newer documentation
that might provide some clues. There's a "redpiece" that got published
recently here:

Starting on page 5 there's a brief section on HMC configuration. There
Thanks for the response, Timothy. I've read that book cover to cover but
it doesn't seem to answer my question: are the physical PCICC coprocessors
available to a linux guest running in an IFL?

There's a redbook (SG24-6870) which seems to offer an answer, specifically
in Section 7.1. Here's what it says:
- - - - -
Linux on zSeries does not support the CCF coprocessors. Instead, a generic
device driver, z90crypt, is provided to route the cryptographic work to
the PCICC or PCICA cards
I'm running two test zVM 5.2 LPARs on a z900 IFL. The z900 has two PCICC
cards installed (4 processors). All four PCICC processors are defined in
the LPAR's access and candidate lists.
There's some confusion (OK, lots) as to the availability of the PCICC
processors to a Linux guest. The Linux mach
