   Hello Debian Kernel Team,   
      
   I'm the Community Manager for the Xen Project. I'm writing on behalf of the   
   Xen Project community regarding a Linux kernel patch that improves   
   virtual-machine performance on AMD EPYC systems running Xen or KVM (with   
   Xen emulation).   
      
   The patch addresses a communication-performance issue between VMs on the   
   same host. A workaround already exists downstream, but inclusion in Debian   
   11’s 5.10 kernel would ensure stable performance without manual   
   adjustments. Greg KH declined to backport the series to 5.10 stable as it’s   
   a performance improvement rather than a bug fix, but it has proven reliable   
   in testing.   
      
   Patch reference:   
   - Mainline patch by Juergen Gross (SUSE)   
      
   or its backport:   
   - Backport by Teddy Astie (Vates)   
      
      
   Would you consider integrating this patch into Debian 11’s kernel?   
   Please let us know if you prefer that we open a bug for tracking.   
      
   Very best regards,
