So the msi=1 param replaces the msi_irq_enable param. This is a recent change right?

Hi Stephen Spector, Can you help to update the Xen wiki http://wiki.xensource.com/xenwiki/VTdHowTo ? Thanks! ----------------------------- How to enable MSI/MSI-X for assigned devices? Before changeset 18127: 89d05940cc1c: Add an option "msi_irq_enable=1" in grub. It should appear like "kernel xen.gz msi_irq_enable=1 <your other options>".>From changeset 18127: 89d05940cc1c to changeset 18453: 7f1c71c6d4c8:The paramerter is "msi=1">From changeset 18454: 65dc37be0443 on, we always have msi=1. We can''t use a Xen grub parameter to set the value.----------------------------- How to list the currently assignable devices in a host?>From changeset: 18047:39c2cab9e765 on, there is a shell utility "xm pci-list-assignable-devices".The utility finds all the devices owned by pciback, checks if they have proper FLR method, checks if they have page-alinged MMIO BARs, and checks if the devices have been already assigned, finally it prints out the assignable devices. Note: the utility assumes the integrated devices (whose bus numbers are 0) have proper FLR method. -- Dexuan -----Original Message----- From: Akio Takebe [mailto:takebe_akio@jp.fujitsu.com] Sent: 2008年9月11日 12:15 To: Han, Weidong Cc: Cui, Dexuan; xen-devel@lists.xensource.com; Ross Philipson Subject: Re: [Xen-devel] [PATCH] [VTD] Update vtd.txt Hi, all Someone have the permission?
