Hi,
In guest Linux and Windows using short format VHPT,
there is no performance degradation for this patch.
So I wish it to be applied.
(and besides my machine's PAL is 8.09)
Even on latest PAL, the following patch is needed.
if(vpta.vf){
pval = ia64_call_vsa(PAL_VPS_THASH, vadr, vrr.rrval,
vpta.val, 0, 0, 0, 0);
- pval = vpta.val & ~0xffff;
}else{
vhpt_offset=((vadr>>vrr.ps)<<3)&((1UL<<(vpta.size))-1);
pval = (vadr & VRN_MASK) |
Thanks,
Kouya
