DataLA profiling upon TSX abort event?

Hi all,

I was looking at Intel SDM V3, section 18.10.5.1 Intel TSX and PEBS Support. Specifically, I am interested in the available PEBS support upon a RTM abort event. I saw that in the previous manual version (August 2012), there was an additional line suggesting that a DataLA field would be available (valid in the PEBS record):

Offset 0x98 Data Linear Address (if the uop that triggered PEBS was a load or a store),

But this line has been removed from the newer version of the manual. Could someone confirm or tell me about the possibility of DataLA profiling upon a transaction abort?

Thanks,
Sylvain

DataLA is not supported for TSX abort events, that is why it has been removed from the SDM.

OK, that's a pity

Thanks for the confirmation
