07:27 <lumag> elder: inside the IPA driver, would it be possible to load firmware on ndo_open() instead of probe time? It's not untypical to have IPA driver in the initramfs, with the firmware being available only after rootfs mount.

12:53 <elder> Maybe. It would move a bunch of the late stage initialization to that point, and we would have to ensure it happened only in the first ndo_open call. In many cases it’s not the AP that does the firmware load, but when it does I think that could work. I just fear we might bump into another issue while trying.

12:53 <elder> Anyway I think the answer is a cautious “yes.”

14:48 <Tofe> I just remarked that my downstream kernel used the rx_to_inject property in the msm_serial_hs_platform_data struct, for the uartdm... is there a matching way to inject that byte using upstream code ?

17:06 <lumag> elder: thanks!
