Title:
Please add support for Qualcomm IPC Router in 5.4 focal kernel
Status in OEM Priority Project:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
The modemmanager debian package in focal was recently upgraded to 1.18
(the jammy version was backported - see LP: #1965901). This version
has broken some Qualcomm modems as it start to require the Qualcomm
IPC Router for them, which drivers are not enabled in Ubuntu kernel
5.4. To fix this we need these options enabled in the focal kernel:
CONFIG_QRTR=m
CONFIG_QRTR_SMD=m
CONFIG_QRTR_TUN=m
CONFIG_QRTR_MHI=m
The options are already enabled in more modern Ubuntu kernel, i.e.
5.17.
