Hi,

this commit d54468e introduces SPI CS handling in the spi controller driver while it should be and is handled in spi_transfer_one_message().
https://github.com/intel/linux-intel-lts/blob/5.15/linux/drivers/spi/spi.c#L1361

This breaks any message consisting of two transfers, e.g. generated by spi-nor via spi-mem.
https://elixir.bootlin.com/linux/v5.10.156/source/drivers/spi/spi-mem.c#L329

spi-nor constructs a message consisting of at least two transfers, one byte for the command SPINOR_OP_RDID and another one for the response id. https://elixir.bootlin.com/linux/v5.10.156/source/drivers/spi/spi-mem.c#L329
Releasing the chipselect after SPINOR_OP_RDID interrupts the transfer, so no chip id is read.

To my knowledge this patch never made it into vanilla kernel as well.

Best regards,
Markus

Hi. There is a missing file, .config in 5.4/yocto branch which causes building debian package to fail.

Makefile:632: include/config/auto.conf: No such file or directory
Makefile:678: include/config/auto.conf.cmd: No such file or directory

*** Configuration file ".config" not found!

*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").

Makefile:681: recipe for target '.config' failed
make: *** [.config] Error 1

With the kernel v5.15.129 and using the i915 driver as built-in module on my hardware it hang the kernel load on the follow log:

[drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0

Making some debug by print I reach the i915_hwmon_register which is the function that does not return.
My hardware is an Intel(R) Atom(TM) x5-Z8350

Interestingly, this did not occur in v5.10...

Hi Intel Kernel Team,

I noticed a compilation issue.
I use 4.14/base - 4.14.212 + 4.14/base-cve - CVE quilt release for 4.14/base : 210126T093613Z.

drivers/crypto/ccp/ccp-ops.c: In function ‘ccp_run_sha_cmd’:

Maybe a patch from CVE, it's not completed.
Can you help me with this problem?

I know they recommend using the 4.4 kernel with the patches they provided, but I am wondering if the same gpu libraries should work with the patches currently present in this repo.

Hi,
What is the difference/aim of this kernel vs the mainframe linux branch ?
Regards,
S.Ancelot

i noticed that the i915 fixes a lot of errors and enabled SR-IOV feature. When will it be merge into the linux mainline?

I bought a mini-PC as my home server with a Core i7 12650H inside it. Now I want to make use of its iGPU SRIOV feature to share the ability of parallel computation across multiple VMs. By now, all the tech blogs available to the public are using KVM as hypervisors when enabling the iGPU SRIOV feature. But I'm looking for a type-I hypervisor to achieve better stability and isolation. I'm listing the questions I want to know below:

1. Theoretically, is Xen expected to work correctly with the current i915 SRIOV driver?
2. Have there been any tests by Intel or will I be the first to experiment?
3. If the driver cannot work correctly, will there be a high possibility of breaking the hardware? (say if the firmware is not loaded correctly)

Hi Intel Kernel Team,

I try to build this kernel, but observe issue on compile.
I use 4.14/base branch for create a new kernel.

Hello,

Anytime I restart my up2 board with the 8260NGW wifi card installed it doesn't work. A cold boot works just fine. A 7265NGW works just fine. I'm hoping this is a kernel issue, rather than a BIOS bug as I have been unable to get even basic support from AAeon or emutex for their the up2 board.
Running 4.9.126-intel-pk-standard on latest BIOS v3.3.

Firstly, on Windows 11 using ffmpeg 6.0, ffmpeg -i Downloads/FPS_test_1080p60_L4.2.mkv -c:v vp9_qsv -f null test just hangs. So for whatever reason a Windows guest cannot use VP9 encoding.

Secondly, when a Windows 11 guest is running a h264/h265 encode (Eg. ffmpeg -i Downloads/FPS_test_1080p60_L4.2.mkv -c:v h264_qsv -f null test) and a linux guest (sharing the same partitioned iGPU) starts a VP9 encode, the Window's encode locks up. Stopping the linux encode allows the windows encode to proceed as expected.

I haven't tried a linux-linux scenario.

Isn't this bad behavior? It seems like a linux guest is able to deny access to the quicksync encoder for any other Windows guest.

Header files does not mention any license but .c files does. Can we safely assume that header files are also dual licensed like .c files?

Hello,

Something I've been wondering about, is it possible to create a fake/virtual monitor with the SR-IOV feature ?

Currently, when passing-through the VF devices inside a Windows guest, there's no display/monitors attached to them which makes it impossible to have an accelerated display (we are stuck using a remote display protocol currently from my research and understanding).

There's currently two approaches I think that could solve the problem:

• Modify the Intel GPU driver inside the Windows guest to have the possibility to create dummy video output so that https://looking-glass.io can be used ? (it means that Intel needs to modify the proprietary Windows driver)
• A virtual monitor could be created, so that we can display inside the linux host the Windows guest by modifying the i915's SR-IOV driver somehow ? (I could do that if it's possible, but I guess I'll need some guidance)

Sorry if it has been already answered, already asked or solved.

Thank you.

I am unable to get audio over i2s working on EHL B0 using Beta 3 FW. I am using 5.4/yocto branch and get the below errors after booting. I already have the sof/sof-tplg in place as well.

Is there BIOS changes that are needed to enable audio over i2s on EHL?

config-5.10.52.txt

Hi team,
I am new to this group and looking for kernel which support TGPIO for Xeon SPR-EE platform. After compile the kernel "linux-intel-lts-lts-v5.15.113-rt64-preempt-rt-230530T192215Z.tar.gz" and reboot the system, it stuck on nothing but a cursor on left-up corner of screen.

May I know if kernel in this linux-intel-lts is suitable for Xeon-SP? Thank you for help.

Having Raptor Lake-P laptop (Dell Precision 3581, 13th Gen Intel Core i7-13700H), i915 driver with SR-IOV brings the issue with sleep mode. Even without /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs initialization the system (Fedora 38) unable to get back from sleep - only power-off via button longpress can reset it.

I tried i915 as DKMS module with various kernel versions up to 6.3.8 and just plain Intel LTS kernel from this repo (including today's 6.1/linux branch) - the behavior is the same: everything works, I even have Windows QEMU VM with vGPU passed through with great FPS in 3D tests, but... the host just hungs forever right after sleep. I tried to disable rc6, most of "workarounds" in boot string, nothing helps. I would appreciate any idea that will help to remove this roadblock on the way to have a great SR-IOV Iris XE feature.

After updating to the latest version of meta-intel, the PSE Ethernet on our Elkhart Lake hardware stopped working. In tcpdump, we are seeing complete corruption of the headers of received packets. Example of a DHCP packet:

The corruption spans the first 42 bytes, exactly the length of the Ethernet+IPv4+UDP headers.

Both lts-v5.10.41-yocto-210621T194959Z and lts-v5.10.41-yocto-210707T232614Z are affected (I haven't tested other versions). A bisect found d95b18b ("stmmac: align RX buffers") as the culprit; reverting this commit solves the issue.

Can support be added for CRL driver framework and IPU4 for Apollo Lake?

Hey there,

I cannot find any way to use the XMM 7360 LTE on any linux based hostsystem. It is built in an HP G5 Elitebook and I have to carry an extra LTE modem. Since the notebook has only two usb slots, it is pretty annoying for mobile use case (the two slots are no problem of intel, though).

The respective output of lspci -nnk is as followed:

3b:00.0 Wireless controller [0d40]: Intel Corporation Device [8086:7360] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:8337]

No kernel module is mentioned.

I'm considering whether to upgrade my G7400. Can the i5-13400 use SR-IOV?

Hi Intel Kernel Team,

I also tried to change revision number but still got the error.
Can anyone help with this issue?

Thanks

Alchemist has been released, and I think these technical details should be revealed should no longer be limited by the NDA.

Since drivers for SR-IOV have already been completed in this fork, could these drivers be mainlined into the kernel?

4.14.170-intel-lts-base - 4.14/base

Hello,

I've been trying to figure out how to get the XMM 7560 working on my HP Spectre Folio's Ubuntu install. As far as I can tell the drivers would end up implemented here, but it's not done yet.

Output of lspci -nnk:

6d:00.0 Wireless controller [0d40]: Intel Corporation Device [8086:7560] (rev 01)
	Subsystem: Hewlett-Packard Company Device [103c:8507]

I figure this is closely related to #7 but it seems sensible to track it separately.

Alternately, Is there enough publicly available information on the XMM 7560 to write a driver for it? Low level PCI interface docs? Source for the windows driver? It's been a while since I've written a device driver, but as long as I don't have to reverse engineer the thing from assembly I'd be willing to try.

Hi Intel Kernel Team,

I observe this:

Is a kernel regression with ACPI component?

Not certain how you want these, but I keep having this kernel error pop up on every boot. Using an Up2 board with NV4200. Primarily using default kernel options from meta-intel and meta-up-board, with a just a few extra kernel modules compiled in.

Hi Intel Kernel Team,

I try to compile new version with 5.10 branch.
But i notice one issue with MTD config option.
I can't enable it. And if I write it to the .config configuration file, it disappears during make oldconfig.

CONFIG_MTD_PSTORE=m

1. with issue: linux-intel-lts, branch: 5.10/yocto, version: 5.10.52, sha: 2241189
2. with not issue: linux-intel-lts, branch: 5.10/yocto, version: 5.10.47, sha: 3ebd33d

Is a kernel regression?

Have a good day.

I compiled the kernel at TAG: lts-v6.1.8-linux-230201T082419Z

• CPU: 11th Gen Intel i7-1165G7 (8) @ 4.700GHz
• GPU: Intel TigerLake-LP GT2 [Iris Xe Graphics]

I created 7 VFs with:
sudo bash -c "echo 7 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs"

sudo systemctl hibernate freezes the machine with the display turned off.
I must force it off and boot again.

If I run
sudo bash -c "echo 0 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs"
before sudo systemctl hibernate the hibernation works without issue.

I checked dmesg and the last entry is Mar 03 09:48:13 Elizabeth kernel: PM: hibernation: hibernation entry with no obvious error present.

I just tested sudo systemctl suspend exhibits the same issue.

suspend.dmesg.txt

The commit ec9d20c introduced a bug that results in chips not responding any longer.

This was analyzed one year ago in this issue #38 but the bug was reintroduced in May by the commit mentioned above.
