Regarding offcore requests

Hi all,

Will the offcore requests that are blocked due to superqueue full be discarded ? Then the front-end will issue them later when the superqueue is available ?

I found the following two events interesting:
OFFCORE_REQUESTS.ANY
OFFCORE_REQUESTS_SQ_FULL

My question is:
Does OFFCORE_REQUESTS.ANY also count the requests that are blocked ? (i.e. OFFCORE_REQUESTS.ANY is a super set of OFFCORE_REQUESTS_SQ_FULL), or OFFCORE_REQUESTS only counts admitted requests by the superqueue?

Thanks.

OFFCORE_REQUESTS.ANY? I only found OFFCORE_RESPONSE_0 which can measure all cache line activities, but OFFCORE_REQUESTS_SQ_FULL only measures the latency (cycles) when SQ is full.
