Subject: [dpdk-dev] [PATCH] igb_uio: fix vmware e1000 input/output error
Date: Mon, 21 Mar 2016 17:01:14 +0800 [thread overview]
Message-ID: <1458550874-15709-1-git-send-email-qian.q.xu@intel.com> (raw)
In vmware esxi 6.0, add the emulated e1000 device to guest, then
launch the VM, we will see the error meassage as below:
EAL: Error reading from file descriptor 21: Input/output error
INTX is badly emulated in Vmware, INTX toggle check didn't work
with Vmware e1000 device. The patch is to fix the issue. And the
patch is from http://dpdk.org/dev/patchwork/patch/945/, so Masaru
OKI is the author. Qian just updated the patch for latest code.
