...or first slight signs of screen corruption (white rectangles around window frames) at the times of the hangs. The error messages that I find in /var/log/messages probably associated with the hangs (sorry, I can't get any messages ot of dmesg due to the hang...) seem to be the following: [drm:drm_mm_takedown] *ERROR* Memory manager not clean.

Hi all, First thing first: It works, I now no longer have a few dropped frames every 10s on my testbox here with the pageflip i-g-t tests. Random notes: - New design has per-crtc locks to protect the crtc input-side (pageflip, cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It also required completely revamped fb lifecycle management, those are now refcounted

Hi, This is third approach (complete this time) for replacing struct dma_attrs with unsigned long. The main patch (2/45) doing the change is split into many subpatches for easier review (3-43). They should be squashed together when applying. *Important:* Patchset is *only* build tested on allyesconfigs: ARM, ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests for other
