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
