Title:
Please add support for Qualcomm IPC Router in 5.4 focal kernel
Status in linux package in Ubuntu:
Incomplete
Bug description:
The modemmanager debian package in focal was recently upgraded to 1.18
(apparently the jammy version was backported). 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.
