PCI Passthrough with 1068e onboard SAS controller

I am trying to pass a sas controller to a osol vm, has anyone got this working?

I followed the instructions here http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM to build the kernel with the correct options. I don't see anything in dmesg about iommu but i do see the following for DMAR. This is a supermicro X8ST3-F motherboard with the latest bios and vt-d enabled.

Code: 
dmesg | grep -e DMAR -e IOMMU
ACPI: DMAR 00000000df79e0d0 00120 (v01    AMI  OEMDMAR 00000001 MSFT 00000097)
I get the following errors when i boot osol build 133

Code: 
WARNING: /pci@0,0/pci15d9,5@5 (mpt0):
unknown ioc_status = 0
scsi_state = 0, transfer count = 0, scsi_status = 0
WARNING: /pci@0,0/pci15d9,5@5 (mpt0):

etc
and this error if i try to pass the controller into a windows 2008R2 vm (with osol shutdown), there are no devices on port 0 of the controller.
Code: 
The driver detected a controller error on \Device\RaidPort0.
and finally this error and stalls when trying to boot up a gentoo vm
Code:

dmesg shows shows that i have successfully unbound the device and bound it to the stub driver with this code

Am i missing something?
 
I suggest you test again as soon as we released pve-qemu-kvm 0.12.3
 
is pve-qemu-kvm 0.12.3 something that has already been released and i just cant find it?
 
not released, currently testing in our test lab.
 
do you happen to know when this might be released to the masses? few days or few weeks?
 
Current proxmox kernel 2.6.32-2-pve lacks DMAR/IOMMU support, at least for Intel platform.
To use PCI passthrough, please add following parameters to the kernel configuration:
CONFIG_DMAR_DEFAULT_ON=y
CONFIG_DMAR=y

I have tested this successfully with L5520 CPU and 5520 chipset. Hopefully it will be included in next Proxmox kernel release.

Hi, I need your help. Pleas tell me How to do it. Please post short how-to with it.

Where can I take src for 2.6.32-2-pve kernel?

That's a question I asked in another thread also, and Proxmox staff haven't answered it yet. Source should be at ftp://download.proxmox.com/sources/ but pve-kernel-2.6.32_2010-02-04.tar.gz builds into 2.6.32-1-pve kernel and 2.6.32-2-pve source is missing. For now, I used what's available and just changed the configuration. It's supposed to be quite straightforward -- download, unpack and run make.

Unfortunately the source package, when unmodified, does currently not build an identical kernel to the distributed binary. The catch is, that this 'source' does not contain actual kernel source, but depends on Ubuntu kernel repository to which it adds only proxmox-specific changes. Ubuntu repository contents have evolved in time and some configuration patches even don't apply cleanly, so you either have to hack it together on current sources OR do a checkout from the exact date when actual proxmox binary packages where built.
While otherwise Proxmox VE is a great product, I am somewhat dissapointed for the source issue. When I started to look for sources, I was hoping for debian source packages and/or a public git tree, but found only some outdated code drops.

I make it by:

Please tell how to do it correctly.

I need help. I'm not clean about make kernel.

Are you kidding me?
This pve-kernel-2.6.32_2010-05-25.tar.gz package contains exactly the same source as previous pve-kernel-2.6.32_2010-02-04.tar.gz (which, strangely, is not available any more).
Code: 
diff -urN pve-kernel-2.6.32_2010-02-04/ pve-kernel-2.6.32_2010-05-25/
gives zero differences.
Also, there is KREL=1 in Makefile, so it certainly doesn't compile into pve-kernel-2.6.32-2-pve. Neither does it correctly reproduce a pve-kernel-2.6.32-1-pve package, as make fails with
Code: 
cd linux-2.6.32; patch -p1 <../disable-fsam7400.diff
patching file ubuntu/Makefile
Hunk #1 FAILED at 5.
1 out of 1 hunk FAILED -- saving rejects to file ubuntu/Makefile.rej
make: *** [linux-2.6.32/README] Error 1
Even after patching it up into a compilable state, it doesn't compile into same kernel that is distributed in binary package. Distributed binary package is pve-kernel-2.6.32-1-pve_2.6.32-4_amd64.deb but Makefile contains PKGREL=5 and as all patches don't apply, I'm pretty sure that the source has changed.

As Proxmox VE is licenced under GPLv2, you have to provide source for all distributed binaries. And not just any random source, but exactly the source that builds into distributed binaries. I haven't looked into other packages, but kernel source distribution certainly has problems.
 
With the current unmodify kernel I have this error:

We always release the sources a few days after we update the repository. To save bandwidth, we try to make the packages as short as possible. If you really want to waste our time, I can burn and send you a CD with all sources included.
