Hi,
The ondemand delay value is calculated before calling dbs_check_cpu
which can lead to a delay value of sampling_rate*sampling_down_factor
but a frequency set to the lowest value. The main result is a slow
responsiveness during this period. This patch moves the calculation of
delay after the ca
I have now updated the spec with your comments, thanks!

Rob,
It is certainly analogous to the DRM access control interfaces, and I would
expect that access to memory objects from the graphics stack would go
through those interfaces (i.e. Xorg/EGL calls libdrm, calls DRM kernel
ioctl, calls memory manger inside the kernel), but we need to make sure we

What do you mean "write back is disable" ? You can only prevent
writebacks by using a write-through cache.
Any writeback cache, whether

Hi Jim, great work!
** Why can't we execute LAVA/Abrek directly on Android devices?
I agree that direct abrek is not the right solution for Android. I think
there is a class of use cases that also falls into this category:
