Subject: [dpdk-dev] [PATCH 0/2] fix virtio interrupt handling
Date: Mon,  9 Mar 2015 15:56:37 +0100
Message-ID: <1425912999-13118-1-git-send-email-david.marchand@6wind.com> (raw)
In-Reply-To: <CALwxeUuQtv685KnbmpZKCPkrAqmjLs558xeCW7c=-TPTsB423w@mail.gmail.com>

This patchset fixes a segfault in eal linux when using virtio pmd with link
status change interrupts in place because of an incorrect io privilege level.


Ouyang,

Fixing this has revealed some problems to be fixed (for 2.0.0 at least for the
first):
- changing link status from qemu monitor triggers this error message (even if
  link status seems to be correctly set)

testpmd> EAL: Error reading interrupts status for fd 0

- log macros in virtio pmd (especially for init) are still under a build option.
  They should be aligned on other pmds to make it easier to debug, see ixgbe pmd
  and/or thread:
  http://dpdk.org/ml/archives/dev/2014-September/005450.html

Can you look at these ?

Thanks.
