[PATCH] Revert "drm/amdkfd: only allow heavy-weight TLB flush on some ASICs for SVM too"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This reverts commit a129dbca92edaeb5a515a0e5b63ada71cf9b981a.

It causes SVM regressions on Vega10 with XNACK-ON. Just revert it
at the moment.
