After a lot of patience(!) I now have a much-hacked version of Gentoo running on the HP RX2600, and have just updated the kernel to 4.15-rc9:
.................. [ OK ] Reached target Multi-User System. [ OK ] Reached target Graphical Interface. This is rgia64.unknown_domain (Linux ia64 4.15.0-rc9) 19:42:44 root@rgia64 ~ # uname -a Linux rgia64 4.15.0-rc9 #1 SMP Sun Jan 21 18:34:32 PST 2018 ia64 Madison GenuineIntel GNU/Linux root@rgia64 ~ # cat /proc/cpuinfo processor : 0 vendor : GenuineIntel arch : IA-64 family : 31 model : 1 model name : Madison revision : 5 archrev : 0 features : branchlong cpu number : 0 cpu regs : 4 cpu MHz : 1500.000 itc MHz : 1500.000000 BogoMIPS : 2246.65 siblings : 1 physical id: 0 processor : 1 vendor : GenuineIntel arch : IA-64 family : 31 model : 1 model name : Madison revision : 5 archrev : 0 features : branchlong cpu number : 0 cpu regs : 4 cpu MHz : 1500.000 itc MHz : 1500.000000 BogoMIPS : 2246.65 siblings : 1 physical id: 3
I have had problems with some web-related software, and some of this is explicitly prevented from compiling:
QtWebEngine can only be built for x86, x86-64, ARM, Aarch64, and MIPSel architectures.
QtWebEngine will not be built.
Firefox and Konqueror failed to compile, with ‘inlining‘ errors, and I have been unable to find a workaround, despite changing compiler parameters etc,..
The Gentoo java is no longer available, but I was able to get a reasonably recent IA64 version from the Sun/Oracle site..
root@rgia64 ~ # java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b0602)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b17, mixed mode)
At least the actual Kernel still compiles OK, but I found that the Gentoo instructions for EFI were a bit odd, and so kept the Fedora setup.. After
# make install, I have to copy the kernel vmlinuz… image to
/boot/EFI/EFI/redhat,and create the initrd there manually, but this works OK..
