dc block memory access impact metrology

[sylvain.bertrand at gmail.com]

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,
