[Bug 489846] New: pci passthrough error "non-page-aligned MMIO BAR found"

Please use the "reassigndev=" command line option,
will do ...
which is a requirement
i've clearly missed this ... hints as to where it's mentioned?
to pass through devices that have misaligned MMIO regions (and that you can't make the BIOS assign at a page boundary).
if i add reassigndev=(04:07.0) should physdev_dom0_hide=(04:07.0) also/still be used? removed? not clear about the relationship, if any, between the two. thanks! -- 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.

Such a kernel option simply doesn't exist to my knowledge. Hiding is done by using either pciback's pci_devs_to_hide= option or the sysfs interface. Second, the format of the value to be passed to reassigndev= is a comma separated list of ssss:bb:dd.f or bb:dd.f (i.e. without any parentheses). The reason I closed this and 489735 as invalid is because you're not really reporting bugs here - you're rather asking support style questions, which you should be using mailing lists for (not sure if there are any other support methods for OpenSuSE products). -- 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.

hm. that's news to me, http://wiki.xensource.com/xenwiki/XenBooting?highlight=%28physdev_dom0_hide%... "physdev_dom0_hide=List of PCI slots to hide from domain 0, Format is '(%02x:%02x.%1x)(%02x:%02x.%1x)' and so on." although, my cp-n-paste mistake above -- it's on the kernel line ... afaict, there's no mention whatsoever of "pci_devs_to_hide" @ the xen site can you share where that's documented?
Second, the format of the value to be passed to reassigndev= is a comma separated list of ssss:bb:dd.f or bb:dd.f (i.e. without any parentheses).
ok, thanks. again, no mention on the xen wiki or opensuse sites. did find, http://article.gmane.org/gmane.comp.emulators.xen.devel/56940 docs?

well, ok. i'll disagree -- reporting reproducible "errors" that are a result of not-implementing un-documented parameters seems legitimate as a bug -- not a support issue; but my opinion doesn't matter here. thanks. -- 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.

I'm looking at the sources. But sorry, the module option really just is hide= (but still doesn't belong on the´kernel line for our kernels).

that's a completely _different_ discussion about xen, xen on opensuse & xen on sles ;-) anyway, made the recommended changes; now getting a crash. per suggestion, reticently moving this to the lists, http://lists.opensuse.org/opensuse-virtual/2009-03/msg00015.html -- 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.
