Hi Andi,
What problem do they cause together? There's certainly no problem with
Xen+vdso (in fact, its actually very useful so that it picks up the
right libc with Xen-friendly TLS).
Methinks the compat VDSO support got broken in the config? Paravirt +
COMPAT_VDSO are incompatible.
Yes, that's true, but I'm looking at arch/i386/kernel/sysenter.c:
#ifdef CONFIG_PARAVIRT
unsigned int __read_mostly vdso_enabled = 0;
#else
unsigned int __read_mostly vdso_enabled = 1;
#endif
I can't think of any reason why that should be necessary.
It's not for us or Xen. Perhaps it came from lhype?
