[Intel-gfx] i915 driver slowdown after 1-2 days?

[Clemens Eisserer]

Hi,

It would be interesting to know wether the slowdown also occurs
without suspending the system.

A good debug-tool for slowdowns like this is "sysprof", simply install
all relevant debugging symbols,
wait for the system to become really slow - and run sysprof while
excercising the system's slowness.
This should give some idea where all the time is spent.
