SRU: http://10.131.201.69/kernel/jammy-linux-oem/pulls/77 (linux-
oem-6.5)
** Description changed:
[SRU Justification]
+
+ ========== linux/linux-oem-6.5 ==========
+
+ [Impact]
+
+ Need kernel driver fixes for int3472/iommu for Intel IPU6 platform on
+ MTL.
+
+ [Fix]
+
+ Two fixes in need. One, we need IOMMU passthrough for MTL platform. The
+ other, fix is for handshake pin support for Lattice MIPI aggregator.
+
+ [Test Case]
+
+ ```
+ $ sudo dmesg | grep "Passthrough IOMMU for integrated Intel IPU"
+ $ sudo dmesg | grep int3472
+ # should have no "int3472-discrete INT3472:0c: GPIO type 0x12 unknown; the
sensor may not work"
+ ```
+
+ [Where problems could occur]
+
+ IOMMU Passthrough as necessary to enable IPU6 on Intel platforms, and it
+ has been patching a few generations e.g. Bug 1989041 for Raptor Lake,
+ Bug 1958004 for TGL and ADL. As IPU is not an external facing device
+ which is not risky.
+
+ For INT3472, the proposed patch might receive further updates per
+ current upstream reviewers' opinions.
+
+ [Other Info]
+
+ Nominated for linux/mantic and oem-6.5/jammy as they're for MTL.
+
+ ========== linux-firmware ==========
[Impact]
Missing Intel MIPI firmware for Meteor Lake platform.
[Fix]
Firmware blobs from upstream ipu6-camera-bins repository.
[Test Case]
With firmware loaded correctly, there should be firmware version
printed:
intel-ipu6 intel-ipu: FW version: 20220510
For camera functions, we'll need also updates in the ipu6-drivers,
ivsc-drivers
dkms as well.
[Where problems could occur]
This is a new platform. We've been verifying its functions and features, and
are still polishing it.
[Other Info]
While Intel Meteor Lake is only supported by linux-oem-6.5/jammy and
linux/mantic, so only Jammy/Mantic are nominated.
** Changed in: linux (Ubuntu Mantic)
Status: Triaged => In Progress
** Changed in: linux-oem-6.5 (Ubuntu Jammy)
Status: Triaged => In Progress
