Hi, all: When gfx executes batch buffer in render ring buffer, it will do context switch . Since only when the previous batch buffer has finished, the next batch buffer can start. the batch buffer is executed in order. So I think there is no need to do context switch. Why i915 driver introduce context switch ? If context switch is disabled, what error will occur ? Why gfx need context switch, can somebody give me a example to use context switch ? Thanks in advance.
