SRU v2: https://lists.ubuntu.com/archives/kernel- team/2023-October/146475.html (mantic)
** 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. + + The Intel IPU6 camera drivers are not yet all upstreamed yet. So far + Intel VSC, LJCA (the previous MIPI aggregator for ADL/RPL platforms) are + in v6.6 already, and IPU6 ISYS is under upstream review. More components + to come according to Intel. + + These two fixes are therefore for related components for not-yet fully + upstreamed IPU6 as needed for out-of-tree dkms drivers. [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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2031412 Title: Support mipi camera on Intel Meteor Lake platform Status in HWE Next: New Status in ipu6-drivers package in Ubuntu: New Status in ivsc-driver package in Ubuntu: New Status in linux package in Ubuntu: Triaged Status in linux-firmware package in Ubuntu: Fix Released Status in linux-oem-6.5 package in Ubuntu: Invalid Status in ipu6-drivers source package in Jammy: New Status in ivsc-driver source package in Jammy: New Status in linux source package in Jammy: Won't Fix Status in linux-firmware source package in Jammy: Fix Released Status in linux-oem-6.5 source package in Jammy: In Progress Status in ipu6-drivers source package in Mantic: New Status in ivsc-driver source package in Mantic: New Status in linux source package in Mantic: In Progress Status in linux-firmware source package in Mantic: Fix Released Status in linux-oem-6.5 source package in Mantic: Invalid Bug description: [SRU Justification] ========== linux/linux-oem-6.5 ========== [Impact] Need kernel driver fixes for int3472/iommu for Intel IPU6 platform on MTL.
