[Xen-devel] bimodal PAE and compatibility



We currently ship a PAE 32-bit domU that we can trivially make bimodal,
except that if we set it to "bimodal", then older Xens will default to
thinking the domU is not PAE:

353     dsi->pae_kernel = PAEKERN_no;
354     if ( dsi->__elfnote_section )
355     {
356         p = xen_elfnote_string(dsi, XEN_ELFNOTE_PAE_MODE);
357         if ( p != NULL && strncmp(p, "yes", 3) == 0 )
358             dsi->pae_kernel = PAEKERN_extended_cr3;

Could we have a new note instead?

thanks
john
