[Bug 745632] New: openSUSE i586 kernel compiled with i686 X86_CMOV feature
https://bugzilla.novell.com/show_bug.cgi?id=745632 https://bugzilla.novell.com/show_bug.cgi?id=745632#c0 Summary: openSUSE i586 kernel compiled with i686 X86_CMOV feature Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: i586 OS/Version: openSUSE 12.1 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: whiteheadm@acm.org QAContact: qa@suse.de Found By: Customer Blocker: --- The kernel config/i386/* files for i586 openSUSE include the CONFIG_X86_CMOV option. This is incompatible with an i586 release as it is an i686 feature. Both the kernel and the userland tools (ie gcc) use the cmov instruction, and therefore don't run on true i585 systems (pre-Pentium Pro/Pentium II). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Using CMOV wasn't an oversight. It was a conscious decision to break with legacy hardware. We decided it was a reasonable requirement to have a CPU manufactured within the last 15 years. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Someone did go through all the trouble to do something specific. It's just that they did it in 2004 for SUSE 9.2 when obsoleting i586 would have been far too aggressive. It's still there, I'd expect, mostly due to inertia. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The legacy kernel-default for ix86 should theoretically still run on i586 systems. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

KMPs will still be i586 though. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The .i686.rpms are not copied to :full/ since they don't match the arch being built for (i586), and so, kmod packages end up in the "unresolved" state: $ osc r -v openSUSE_12.1 x86_64 succeeded openSUSE_12.1 i586 unresolvable: nothing provides kernel-desktop-devel = 3.3.1~jng5-7 needed by kernel-syms nothing provides kernel-pae-devel = 3.3.1~jng5-7 needed by kernel-syms nothing provides kernel-xen-devel = 3.3.1~jng5-7 needed by kernel-syms How was this solved on b.o.o? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Either add a Exportfilter of i686 to i586 repos or (IMHO the better way) build against 12.2 instead. Coolo told me he changed a lot there to get this working again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So any project config should be inherited. So any fix should be done in the configuration of the openSUSE:* projects. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
