Modern Kernel IA64 support?


Yes - I mean Itanium 2s

I'm trying to compile a kernel, presently 4.9.61, and I'm looking for some way to cross compile it for an IA64 system.

I can find a ton of built-in support for x86 flavored things, but nothing for IA64. It appears to still be supported though, at least the source code has arch/ia64 populated.

Did they silently drop support? That'd be weird as intel is still coming out with new chips...


edit::


it looks like invoking make differently gets me a little farther:

ARCH=ia64 make menuconfig

ARCH=ia64 make


but it's still broken and I get a ton of errors...

I think debian does/used to do an ia64 port. When kernel-3.0 came out, we all had our noses shoved into the requirements doc, as it needed certain versions to go of many things. Have you got the requirements to build ia64? If so, you could give us all a laugh by posting the errors :-P.

It is a matter of distro which you are using.

Gentoo offers a lot of exotic choices, also an ia64 installation.

I never stepped into crosscompiling so far.

I am kinda certain gentoo / arch wiki has decent guides. Also there are for sure decent examples on how to do it for the popular arm platform by now.

Most common architecture is amd64 and arm in my point of view.

Distrowatch shows that Gentoo, RHEL, and FreeBSD still support the architecture, so with Gentoo listed, it would appear that it's still supported to me.

I'd take a look at the gentoo ia64 kernel installation wiki page to see if that's any help.

A good way to do it is with CLFS. Even reading the book gives you the howto.

Specifying target architecture for kernel compile

I believe the correct invocation for compiling for any target architecture is:

PLATFORM=target
make $PLATFORM_defconfig ,

where "target" is the architecture specifier.

See /usr/src/linux/README, /usr/src/linux/arch

Your target should be "ia64". Again, see ./arch; it will be the directory name in most cases.


Hope this helps.
