Tristan, How about the patch to upstream? Xiantao -----Original Message----- From: Jes Sorensen [mailto:jes@xxxxxxx] Sent: Wednesday, June 03, 2009 11:07 PM To: Tristan Gingold Cc: Zhang, Xiantao; kvm-ia64@xxxxxxxxxxxxxxx Subject: [patch] vEFI SRAT support Hi, Here's a patch adding SRAT support to the vEFI image. It's fairly basic, simply putting all vCPUs and memory onto node zero. The benefit of creating the SRAT, even for smaller systems is that the current Linux kernels rely on it to count possibly CPUs, and without it, they will allocate per-CPU space for 32 CPUs. It should result in slightly less kernel memory being consumed for small setups and it allows for booting guests with > 32 vCPUs (and > 64 with older kernels). I also changed the ACPI OEM ID to say XenKVM instead of just Xen, hope thats ok. If you prefer, feel free to ignore this part. Last I added a typecase to the memcpy() #define to avoid a compiler warning.
