Hi guys i have a very newbie question about msi. This is my scenario: Dom0: [ 84.379221] get owner for dev 0 get 1 [ 84.379319] map irq failed [ 84.379416] error enable msi for guest 1 status fffffff0 DomU: [ 33.912465] pci frontend enable msi failed for dev 0:8 This is normal?

This means something wrong. Which changeset of xen are you using? --jyh>-----Original Message----- >From: xen-users-bounces@lists.xensource.com >[mailto:xen-users-bounces@lists.xensource.com] On Behalf Of >Antonio Galindo Castro >Sent: 2009年3月26日 9:33 >To: xen-users@lists.xensource.com >Subject: [Xen-users] A question about msi. > >Hi guys i have a very newbie question about msi. >This is my scenario: > >Dom0: > >[ 84.379221] get owner for dev 0 get 1 >[ 84.379319] map irq failed >[ 84.379416] error enable msi for guest 1 status fffffff0 > >DomU: > >[ 33.912465] pci frontend enable msi failed for dev 0:8 > > >This is normal? > >Regards. > >-- >Luis Antonio Galindo Castro aka FunkyM0nk3y >Fingerprint: 237E EFE1 6055 BCEB ACD0 7A49 30FC A883 0044 A85E > >_______________________________________________ >Xen-users mailing list >Xen-users@lists.xensource.com >http://lists.xensource.com/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Antoher question regarding MSI support. When I have a motherboard where two PCIe slots and one PCI slot share an interrupt when using current Xen and kernel with GSI, when I now use Xen 3.4-unstable and latest kernel, it will use the MSI (as the Two PCIe slots are occupied by realtek NICs and their modules are MSI aware). Two different MSI show up in /proc/interrupts. Does this now mean that I can pass-through the PCI slot into a pv DomU, because the GSI is now exclusively used by the PCI slot (what I could not do before, as NICs shared GSI with the network cards)? For your Info: Xen 3.3.1 and latest kernel will not work for me. Thanks, Carsten. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

BTW, if a device can be assigned to a guest are determined by many factor, like FLR support etc (at least for HVM domain).> >For your Info: Xen 3.3.1 and latest kernel will not work for me. > >Thanks, >Carsten. > > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
