Debian with Reiser4-patched Linux kernel on IBM Power8

Debian with Reiser4-patched Linux kernel on IBM Power8

[Jose R R]

Niltze, all-

Looking over the Soflayer bare metal Power8 systems, I see that
Debian's kid, Ubuntu, is the default OS.

http://www.softlayer.com/power-servers

I was pondering an evaluation trial of Reiser4-enabled Debian on IBM
Power8. Up to now I have only successfully tested Reiser4 Software
Format Release Number (SFRN) 4.0.1 on AMD64 baremetal, virtualization
and cloud.

If am allowed to install my own OS,
is there any reason why Reiser4 SFRN 4.0.1-enabled Debian should not
run on Power8? I assume GPT should be selected whereas previously I
have tested -- on AMD64 baremetal and cloud -- only MSDOS disk
partitioning.


Best Professional Regards.

There might be some problems with the endianness of the system.

I have tested Reiser4 on 32bit PowerPC several years ago and as far as I
remember, mounting and using a preformatted partition (mkfs done on an x86
machine) was possible, but a partition formatted on PowerPC was unusable.
I can repeat the tests, if you are interested.

No, I won't bother you with that. Just gathering some preliminary
information prior to efforts at building the PPC Reiser4 UDEB module
for my Debian-Installer (d-i) hack.

Thank you much for your insight on 'endianness of the system'.


Best professional Regards.

Yup. Specifically, bitmap code sucks.
I don't remember details though..
