Hi,
(discret GPU, no vce and no uvd memory access)
Is there some hardware counters which allow us to count how much the GFX/compute block
has its memory stalled because of the DC block ?
I presume the new on-die cache in vega is to mitigate the demanding DC block
over the GFX/compute block.
I started to wonder how effective is this watermark systems (not to mention the
new framebuffer compression) in real life workloads on discret GPUs.
regards,

Sylvain
