Trouble with Intel video drivers for i915
by admin ·
A regression bug in the Intel graphics driver causes the Linux kernel 5.3 with an Intel specific drivers significantly more power than the version 3.4.
The kernel developers James Bottomley has been a bug in the Linux kernel 3.5 arrest, which means that a system consumes significantly more power than its predecessor, with kernel 3.4. Blame for this regression is a patch for the DRM drivers (Direct Rendering Manager) of the Intel i915 graphics chip. The introduction of locking via semaphores should lead under favorable circumstances, even to the fact that less power is vebraucht. The opposite was the case during the operation of an X server on the test system, only an increase had the power to one watt to seven watts results in an X server used with the faulty driver with 14 watts more than doubled.
Now that, thanks Bottomleys detective working the culprit is found, the Intel developers are working on a new patch for their patch.
