Mt6739 Firmware 'link'

The true constraint, however, is memory. Paired usually with 1GB or 2GB of LPDDR3 RAM, the MT6739 exists in a state of perpetual memory pressure. The firmware for this chip is where the Linux kernel becomes a ruthless librarian. It swaps aggressively, compresses pages in ZRAM with breathless frequency, and kills background processes with the cold efficiency of a Thanos snap. Writing a driver for the MT6739 requires a specific paranoia about memory allocation: if you kmalloc too much, the entire UI will jitter. If you leak a single page, the camera app will take three seconds to launch.
