What is mali-renderer? Is it kernel or user thread? When it will be executed? where mali-renderer definition is present? Who will call mali-renderer?
mali-renderer is a user-space thread one will find created only by older releases of the Mali user space driver (for Midgard GPUs up to and including r11p0). It is part of the work submission and work completion communication path between the user and kernel space driver, and would become active on events happening on either side.
