Hello Dave, When I am using "vm -p" command, I feel it is chaotic when too much data is printed. I think it is clear to display one vma each time. In the patch, I compare all vmas with the argument of -s option. If an equal vma is found, it will be printed like below. crash> vm -ps ffff88028ff7d3a0 VMA START END FLAGS FILE ffff88028ff7d3a0 7fff29b71000 7fff29b87000 100173 VIRTUAL PHYSICAL 7fff29b71000 (not mapped) 7fff29b72000 (not mapped) 7fff29b73000 (not mapped) 7fff29b74000 (not mapped) 7fff29b75000 (not mapped) 7fff29b76000 (not mapped) 7fff29b77000 27faad000 7fff29b78000 2807aa000 7fff29b79000 280781000 7fff29b7a000 280787000 7fff29b7b000 280776000 7fff29b7c000 280786000 7fff29b7d000 27f2df000 7fff29b7e000 27f2e0000 7fff29b7f000 27f2e1000 7fff29b80000 27f2d7000 7fff29b81000 28b1ac000 7fff29b82000 28ecc1000 7fff29b83000 28c5c2000 7fff29b84000 28aaf4000 7fff29b85000 28aaf9000 7fff29b86000 289566000 crash> -- -- Regards Qiao Nuohan
