I'm still struggling with getting a system running with the x32 tune. I won't bother quoting my previous message, which didn't prompt any suggestions anyway, since I have a clearer scenario to describe. I built four systems (all with Morty):
1) I built core-image-minimal on a genericx86-64 machine, and it booted fine. 2) I built a core-image-minimal with an x32 tune, and it spewed out a ton of nonfatal bit size errors in grub-efi do_package_qa, but it booted fine. 3) I built a core-image-minimal with a realtime kernel (4.8), and got a bunch of warning messages about inapplicable kernel config items that were left out (all related to other architectures). When I booted it, the boot process hung fairly early on, following "clocksource: Switched to clocksource tsc", although I rather doubt there's anything wrong with the TSC. There's also a "Waiting for removable media..." message a bit earlier, which could be a clue. 4) I built a core-image-minimal with an x32 tune and a realtime kernel, and got the grub errors plus the config warnings. When I booted it, I got an immedate kernel panic, because it was unable to run init. The problem is that the kernel compilation ignored the x32 tune, and builds a regular 64-bit rt kernel, while everything else (executables, shared libraries, and loadable kernel modules) are 64-x32. So the big question is this: is the x32 tune not supported on yocto-kernel-rt 4.8? Or is this just some bug in the recipe, and I'm just the first person to try running this combination? The second smaller question is: am I selecting the rt kernel properly? I put the following in my local.conf: PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto-rt" PREFERRED_VERSION_linux-yocto-rt ?= "4.8%" Then, I created a layer (included in bblayers.conf) that contained nothing but a linux-yocto-rt_4.8.bbappend file containing COMPATIBLE_MACHINE = "genericx86-64" Is this the right way to select an rt kernel for a machine that isn't listed in the actual recipe (it only lists qemu* machines), or is there a way to do this entirely from local.conf? The third possibly unimportant question is: what can I do to get rid of the grub errors and the config warnings? -- Ciao, Paul D.
