Hi,
Moving on to 256 GB guest, the hyp is failing the XENMEM_populate_physmap
hcall in compat_memory_op(). The problem is size too large for continuation
encoding:
/* Is size too large for us to encode a continuation? */
if ( cmp.rsrv.nr_extents > (UINT_MAX >> MEMOP_EXTENT_SHIFT))
return start_extent;
for 256 GB : nr_extents == 0x4000000
Currently at a loss on this one!
Thanks,
Mukesh
