Add one more step in test plan that launch gst to check actual camera behavior.
And, @raof, the section is named "Where problems could occur", and we don't have the hardware specification, we don't have the meaning of the parameters, what's your suggestions to identify "where problems could occur"? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2084059 Title: OVTI08F4:00: number of CSI2 data lanes 2 is not supported Status in ipu6-drivers package in Ubuntu: Fix Released Status in linux package in Ubuntu: In Progress Status in linux-oem-6.11 package in Ubuntu: Invalid Status in ipu6-drivers source package in Noble: Won't Fix Status in linux source package in Noble: Won't Fix Status in linux-oem-6.11 source package in Noble: Fix Released Status in ipu6-drivers source package in Oracular: Incomplete Status in linux source package in Oracular: Fix Committed Status in linux-oem-6.11 source package in Oracular: Invalid Status in ipu6-drivers source package in Plucky: Fix Released Status in linux source package in Plucky: In Progress Status in linux-oem-6.11 source package in Plucky: Invalid Bug description: [SRU Justification] [Impact] OVTI08F4 camera sensor is used in a different hardware config that is not currently supported: ``` $ sudo dmesg ... usbio-i2c usbio-i2c.3.auto: hid INTC10B6 uid VIC0 new uid1 ov08x40 i2c-OVTI08F4:00: number of CSI2 data lanes 2 is not supported ov08x40 i2c-OVTI08F4:00: failed to check hwcfg: -22 ov08x40 i2c-OVTI08F4:00: probe with driver ov08x40 failed with error -22 ``` [Fix] Proposed fix in: * https://github.com/intel/ipu6-drivers/pull/286 There are two parts. One in the kernel tree that is to be SRU-ed in this pull request. It adds two additional link frequencies so that ipu-bridge may probe this case. The other part is in the camera sensor driver itself that goes to ipu6-drivers. [Test Case] With patch applied, install kernel and intel-ipu6-dkms from -proposed pocket: ``` $ sudo dmesg ... intel_ipu7_psys.psys intel_ipu7.psys.40: psys probe minor: 0 intel_ipu7_isys.isys intel_ipu7.isys.40: bind ov08x40 14-0036 nlanes is 2 port is 0 intel_ipu7_isys.isys intel_ipu7.isys.40: All sensor registration completed. ``` Check if camera actually works: ``` $ sudo gst-launch-1.0 icamerasrc ! autovideosink ``` [Where problems could occur] This is a new hardware configuration for OVTI08F4. Expect further issues. [Other Info] So far this configuration is bound to Intel Lunar Lake platform that is only supported by v6.11 kernels and ipu6-drivers/oracular, ipu7/drivers/oracular. Nominate for linux/oracular, linux- oem-6.11/noble and linux-unstable-6.12. ========== original bug report ========== $ sudo dmesg|grep ov0 [ 4.793991] ov08x40 i2c-OVTI08F4:00: number of CSI2 data lanes 2 is not supported [ 4.793997] ov08x40 i2c-OVTI08F4:00: failed to check hwcfg: -22 [ 4.815076] ov08x40 i2c-OVTI08F4:00: probe with driver ov08x40 failed with error -22 --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: gdm 1400 F.... pipewire CRDA: N/A CasperMD5CheckResult: pass DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2024-10-18 (4 days ago) InstallationMedia: Ubuntu 24.04.1 LTS "Noble Numbat" - Release amd64 (20240827.1) IwConfig: lo no wireless extensions. enx00e04c6801fa no wireless extensions. wwan0 no wireless extensions.
