Subject: [PATCH 1/1] Drivers: hv: Bind all vmbbus interrupts to the boot CPU
Date: Thu, 17 Jan 2013 21:00:51 -0800 [thread overview]
Message-ID: <1358485251-13801-1-git-send-email-kys@microsoft.com> (raw)
The default interrupt delivery model in Linux does not support the Hyper-V
vmbus delivery model when the guest is configured with multiple VCPUs. I have
sent a patch to address this - delivering the vmbus interrupt on a separate
IDT vector. Until this patch is applied, bind all vmbus interrupts to the boot
CPU.
