I'm going to give it a spin and Richard, could you please apply Yinghai's
patch to see if your SRIOV code can work properly?
I did a quick test on my machine. This patch doesn't affect the MMIO
allocation on out platform, so SRIOV works fine.
I will spend more time to read the patch to get more understanding about the
problem.
Hi Marek,
Can you boot following branch with "debug ignore_loglevel pci=realloc"
on your setup?
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git
for-pci-allocate-fit-3.18
it has
8f74af9: PCI, x86: Allocate mmio near end of free range
1ff91c1: PCI: Don't allocate small resource in big free space.
108b43b: resources: Add allocate_resource_fit()
b6a22f0: resources: Make find_resource could return just fit resource
cf50e16: resources: Split out __allocate_resource()
on top the v3.18, and it will allocate resource in fit way.
Thanks
Yinghai
Hi Yinghai,
I have built and booted your branch and it works well. Do you want me to
attach some logs?
(I am new here and I have read http://www.tux.org/lkml/ and I don't want
to break some rules for attachment size)
Marek
