We are seeing that this change incorrectly disabled flash attention for Turing cards (cc=75) when llama.cpp was compiled for Volta cards only (cc=70). To fix, check that we have compiled for Volta or greater, and that the card is Turing or greater. If there is a better way to fix, please do advise.
To reproduce the breakage on the current build, compile with architecture
70
and without architecture75
, and generate with flash attention on a Turing card.
