There are these events defined:
PMU_XP_UPLOAD_STARVATION Upload starvation. Signaled when this XP sets the H-bit, perchannel, per-direction.
PMU_XP_DOWNLOAD_STARVATION Download starvation. Signaled when this XP sets the S-bit, perchannel, per-direction.
PMU_XP_RESPIN Respin. Signaled when this XP sets the P-Cnt, per-channel, perdirection.
In the entire " ARM® CoreLink CCN-512 Cache Coherent Network Revision: r0p0 Technical Reference Manual" I see no mention on "H-bit", "S-bit" and "P-cnt" except the above.
Can you explain to me what these are?
I can collect these events but for that reason I don't know how to interpret them.
