Windows Draft Build

Hi,

I'm having trouble building "dpdk.sln" from "windpdk-v18.08-clang" branch of "dpdk-draft-windows" repository using Visual Studio 2019 Community Edition. All projects are set up to use some "llvm" toolset. If I install LLVM Build Tools and switch toolset to Clang-cl, build fails because Platform SDK is not accessible. I tried to add Platform SDK include paths to Additional Include Directories, but ended up with multiple errors, indicating incompatibilities between Windows headers and Clang. Please find screenshots and logs attached.

"Netuio.sln" builds OK.

Dmitry...
Did you install the LLVM toolchain for VStudio:
https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain

You will need to ensure VS is closed before installing it.
It says it supports VS2017, but it will also work with VS2019, if VS2017 is already installed.

ranjit m.

Thanks Ranjit! Wouldn't have guessed I need VS2017 extension
for VS2019 development. "Dpdk.sln" builds OK, will try launching sample apps a bit later. I'm planning to use QEMU and virtio PMD (modern interface, because legacy uses PIO, which is not implemented by netuio) by adding a project similar to existing "librte_pmd_i40e".

Dmitry Kozlyuk

Hi,

Netuio driver consistently fails to install on Windows 10 in QEMU with virtio-net (modern interface). Described below is my attempt to install the driver from clean "windpdk-v18.08-clang" branch of "dpdk-draft-windows" repo. The only change is hardware ID in INF file. What am I doing wrong here?

1. QEMU version: 4.2.0

QEMU command line:

    qemu-system-x86_64 \
        -enable-kvm \
        -cpu host -smp 'cores=4,sockets=1,threads=1' \
        -m 6G \
        -drive "file=$disk,format=qcow2" \
        -nic "user,id=winnet,model=e1000,smb=$HOME/src/dpdk" \
        -netdev 'socket,listen=:10000,id=dp0' -device 'virtio-net-pci,disable-modern=off,disable-legacy=on,netdev=dp0' \
        -netdev 'socket,listen=:10001,id=dp1' -device 'virtio-net-pci,disable-modern=off,disable-legacy=on,netdev=dp1' \
        \
        -vga qxl

2. Loading unsigned drivers is enabled as follows:

Microsoft Windows [Version 10.0.18363.418]
(c) 2019 Microsoft Corporation. All rights reserved.

Z:\>bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS The operation completed successfully.

Z:\>bcdedit.exe -set TESTSIGNING ON
The operation completed successfully.

Z:\>shutdown -r -t 0

After that, the desktop message shows:

Test Mode
Windows 10 Pro
Build 18362.19h1_release.190318-1202

Including this step FTR, it works for other drivers.

3. Device status (no conflicting drivers):

The drivers for this device are not installed. (Code 28)

There are no compatible drivers for this device.

To find a driver for this device, click Update Driver.

Device event log (note the hardware ID part):

4. INF file is modified to include corresponding hardware ID:

Please find "C:\Windows\INF\setupapi.dev.log" attached as "clean_setupapi.dev.log". Using devcon.exe from DDK yields similar result and log.

I also tried to add event tracing to the driver, but the driver doesn't even get loaded, that is, DriverEntry is never called, so the cause shouldn't be in driver code.

Also tried doing this, attaching patches. Got the same result.

I start every new attempt to install a driver variant from clean system restored from disk snapshot. "Userpci" driver from my port installs and binds OK, so this is not an QEMU/Windows incompatibility issue.

Dmitry Kozlyuk

Oh boy! If DriverEntry() is not being called, the loader is finding something wrong and is unable to load the driver.

@Harini: Can Jeffrey (@MS) help here?

thanks,

Ranjit

By trial and error I determined that changing device class from "Net" to a custom one fixes the issue (see attached patch), root cause is still unknown.

From this point, running virtio PMD is blocked by lack of multi-BAR support in NETUIO, which is a separate concern, outside of scope of this thread.

Dmitry Kozlyuk

Dmitry...
This is a very interesting find. Will this change to a custom class allow the driver to load in the native (bare-metal) case, too? Also, Naty (Narcisa) has a patch for multi-BAR support, that we (Intel) were not able to successfully use...but it's working for her. If you'd like to try it out, she can send it to you.

ranjit m.

Hi Ranjit,

I don't have a DPDK-compatible hardware NIC right now, so I can't perform a complete test. However, I was able to successfully install netUIO with multi-BAR patches and custom class for QLogic BCM5706C 1GbE (bnx2 family, hardware ID PCI\VEN_14E4&DEV_164A&SUBSYS_3070103C&REV_02) on bare-metal Windows 10. Thus, installation and multi-BAR discovery works at least for some hardware (can't tell for multi-BAR mapping).

Dmitry Kozlyuk

Finally managed to run l2fwd with virtio PMD. Providing details as promised.

1. For some reason, when l2fwd is running, virtual screen stops updating. The system itself is NOT frozen: l2fwd forwards packets, processes can be launched using QEMU guest agent, input is received and processed. Since this doesn't happen with different driver and ported upstream DPDK, there is obviously a software bug either in netUIO or in draft DPDK, not in QEMU.

2. Testing setup

Validate connectivity:

root@alice# ping 172.16.0.2

3. Patch instruction is a bit involved:

* Base on windpdk-v18.08-clang.
* Import drivers/net/virtio from v18.08 (not attached due to size).
* Apply windpdk-virtio-1.patch (attached).
* Apply multi-BAR patches (not attached due to not being mine).
* Apply windpdk-virtio-2.patch (attached).

There is one patch in windpdk-virtio-2.patch that splits PCI config I/O of arbitrary size to a series of 4/2/1 accesses. It is implemented in user-mode because it was easier to debug, but maybe it should be moved to netUIO, so that any region of PCI config space can be read/written in a single syscall.

Dmitry Kozlyuk

Hi Dmitry,
I did not see any attachment of the above.
Can you send again?
Thanks
William

Attachments are dropped on the dev@ mailing list.
So please send the patches as you would do for a normal proposal, adding a RFC prefix if you prefer to tag them.

David Marchand

This patchset provides reference of the changes made to run virtio-net PMD with Windows draft DPDK, so that this could be reproduced. Is is not intended to be merged neither soon, nor "as is".

Patches must be applied over "multi-BAR" patchset yet to be released by Microsoft, those patches are not included. After applying Microsoft patches, the whole drivers/net/virtio directory from upstream v18.08 must be imported. It is also not included for brevity.

2.25.1

PCI bus kernel driver mandates accessing config space in a series of reads/writes by 4, 2, or 1 bytes. NETUIO driver checks this requirement before performing config space I/O. Users of DPDK PCI bus driver, however, access config space without regard for this requirement.

Make DPDK PCI bus driver split config I/O to a series of 4-, 2-, or 1-byte reads/writes. Each of these operations is a syscall to netUIO.

Hi Dmitry,

I'm looking at this patch and have some questions.

Why do we need these change below?
I thought to add a new Windows driver support, we only need to compile the drivers/net/xxx, and add the device ID to netuio.inf, at the dpdk-kmod repo?

Thanks
William

2021-08-14 08:55 (UTC-0700), William Tu:

1. At the time of the patch there was no dpdk-kmods repo.

2. The patch is for dpdk-draft-windows repo,
which was using Vistual Studio projects instead of meson.

Yes.
Particularly for virtio it would also be required to support reading PCI config space in bus/pci/windows (netuio already provides the support).

Now I understand, thanks. William
