Yeah, I had similar thoughts about how to support multiple counter sizes. It should be relatively easy to add a counter_size field to the pfm_pmd structure and consult that in the overflow handling code. > I think having both 16 > and 32 bit counters would be useful on the cell, the 16 specifically > because one can allocate one counter per VPE. Actually, no. :( The current PMU design only allows counting events from two SPEs at a time (more specifically, two logic units within the CBE at a time). But this is due to how the event signals are routed from the SPEs through the debug-bus to the PMU. -- Kevin Corry [EMAIL PROTECTED] http://www.ibm.com/linux/ _______________________________________________ perfmon mailing list [email protected] http://www.hpl.hp.com/hosted/linux/mail-archives/perfmon/
