Returns free memory size per node in "xm info". This info can help users who want to bind their guest domain in one node of their NUMA machines thought set CPU affinity. I also write IA64 part support which I would send to XEN-IA64 mail-list. Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi Alex: I was looking at an ia64 bug report and noticed that we don''t actually free IRQs in the free_irq_vector hypercall. This would eventually lead to alloc_irq_vector failing. Unless I''m mistaken something like calling pci_disable_device and pci_enable_device can lead to this situation. So I''m wondering what the original problem was and how could we resolve it

...g the array in the request expand from 11 to a variable size negotiated. But it had limits: this extension still limits the number of segments per request to 255 (as the total number must be specified in the request, which only has an 8-bit field for that purpose). The other solution (from Intel - Ronghui) was to create one extra ring that only has the ‘struct blkif_request_segment’ in them. The ‘struct blkif_request’ would be changed to have an index in said ‘segment ring’. There is only one segment ring. This means that the size of the initial ring is still the same. The requests would point to th...
