I am interested in $P$ that is smooth and proper over a field and such that the derived category of coherent sheaves $D^b(P)$ possesses a $t$-structure whose heart is the category of $R'$-modules for some (non-commutative) ring $R'$. Which examples are known? Do all of them support full exceptional collections (see https://en.wikipedia.org/wiki/Semiorthogonal_decomposition#Exceptional_collection)? This question is close to https://mathoverflow.net/questions/383657/bounded-derived-categories-of-which-smooth-projectives-possess-bounded-t-structu
