In gv11b, fb flush is generating membar.gl instead of membar.sys, which is an issue. To fix this issue. following WAR is used: 1. Use bar1 engine id and bind it to a particular pdb, 2. Then instead of a fb_flush, issue a tlb invalidate of the bar1 pdb. Now allocation of vm for bar1 instance block and bar1 binding is done without check for bar1 support. Only bar1 register mapping is done based on bar1 support enabled.
