I'm now testing the mt9m114 on an Asus T100ta with modded atomisp bios option to 02 linux with MX Linux live ahs, containing kernel 6.10.10-1-liquorix-amd64. After adding the required shisp_2400b0_v21.bin I still see the power up message,
but I also have massages like Failed to find EFI gmin variable gmin_V1P8GPIO, using default -1. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.19 in Ubuntu. https://bugs.launchpad.net/bugs/2008111 Title: mt9m114 webcam sensor power-up failed Status in linux-signed-hwe-5.19 package in Ubuntu: Confirmed Bug description: On my ASUS T100TAM (old Bay Trail 2-in-1 laptop) the webcam is the last non-working piece of hardware.
