[Fix] https://github.com/intel/usbio- drivers/commit/fc527affa4654468cdb63f8803eacd1a71b02017 [Test Case] 1. install kernel headers packages. This should include kernel headers for generic-6.8, oem-6.8, linux-hwe-6.8/jammy according to kernel-versions dkms map. linux-oem-6.5 is outdated and is therefore skipped here. 2. install intel-usbio-dkms from -proposed and trigger dkms builds on all mentioned kernel versions 3. reboot into the kernels to check if usbio/gpio-usbio/i2c-usbio modules were loaded automatically as before. 4. the devices with BIOS of 69W or a newer version should work as before. [Where problems could occur] It appears the i2c protocol meant to be governed by this usbio is not in well control by the upstream collaborative peers, such that we fell into various problems due the the mismatch of firmware version, and therefore some ugly patch from Intel was added to work-around that. While we don't have too much details about the design and the solution, all we can do is to deploy extensive tests as possible. [Other Info] While linux-hwe-6.8 uses usbio-drivers/noble, the nominated candidates are Oracular and Noble. ========== kernel SRU ========== [Impact] ov08x40 camera sensor is not working on IPU6 platforms. [Fix] A few changes from upstream kernel as well as a not yet upstreamed patch in the Intel ipu6-drivers GitHub repo. * commit b1a42fde ("media: ov08x40: Avoid sensor probing in D0 state") * commit eea8f730 ("media: ov08x40: Modify the tline calculation in different modes") * https://github.com/intel/ipu6-drivers/blob/Release_20240624/patch/v6.8/0001-media-ov08x40-Add-Tline-calculation-and-handshake-pi.patch [Test Case] The proposed kernel should have been built along with the updated ipu6-drivers dkms. To verify ipu6-drivers alone, one will need experimental kernels from https://launchpad.net/~canonical-hwe- team/+archive/ubuntu/intermediate-kernel. Here are steps for verifying kernels from -proposed pocket: 1. test camera after rebooting into a proposed kernel, 2. run suspend/resume stress test plan. 3. verify camera still working [Where problems could occur] These fixes are quite limited to ipu6/ivsc platforms, and affected no power-consumption or other noticible problem. [Other Info] The fixing commits/patches were meant for in-tree driver, but yet it changes device power up sequence and may affect platforms not interested in IPU6 enablement. It is then duplicated into ipu6-drivers dkms to avoid any unexpected side effect. While some of the fixes are still under upstream review, meaning they're not yet available in any kernel release, linux- unstable/oracular/noble and oem-6.8/6.1x will be nominated for a rebuild against new dkms.
