Hi David, Chris and lists
I am inquiring about the current status of #2024 [1]
Problem: Kernels 5.7.x , 5.8.x, current 5.9-rcs and drm-tip have a large
regression on (some?) Haswell (HSW)
This is verified by _multiple people_ using different methods.
All his is documented in [1] , Kernel 5.6.1
Add support for static memory reserved from Device Tree. Since we're
using GEM buffers backed by CMA, it is interesting to have an option to
specify the CMA area where the GEM buffers will be allocated.

Old Ingenic SoCs can overclock very well, up to +50% of their nominal
clock rate, whithout requiring overvolting or anything like that, just
by changing the rate of the main PLL. Unfortunately, all clocks on the
system are derived from that PLL, and when the PLL rate is updated, so

Hi Dave,
I think we should just completely nuke ttm_tt_bind() and ttm_tt_unbind()
and all of that.
Drivers can to this from their move_notify() callback now instead.
