commit bc421a035e6cc8420866754af35b355c165c6ed2 Author: Eric Dumazet <[email protected]> Date: Mon Jul 29 10:24:04 2013 -0700 atl1c: use custom skb allocator BugLink: http://bugs.launchpad.net/bugs/1221794 [ Upstream commit 7b70176421993866e616f1cbc4d0dd4054f1bf78 ] We had reports ( https://bugzilla.kernel.org/show_bug.cgi?id=54021 ) that using high order pages for skb allocations is problematic for atl1c We do not know exactly what the problem is, but we suspect that crossing 4K pages is not well supported by this hardware. Use a custom allocator, using page allocator and 2K fragments for optimal stack behavior. We might make this allocator generic in future kernels. ** Bug watch added: Linux Kernel Bug Tracker #54021 http://bugzilla.kernel.org/show_bug.cgi?id=54021 ** Changed in: linux (Ubuntu) Status: Fix Committed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1132477 Title: DMA: Out of SW-IOMMU space for xx bytes at device [AR8151 network] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1132477/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
