From cdc81aece8041fd5437bdabde6c543cdeb2891a8 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 26 Nov 2021 11:30:03 +0100 Subject: [PATCH] powerpc/ptdump: Fix display a BAT's size unit We have wrong units on BAT's sizes (G instead of M, M instead of ...) ---[ Instruction Block Address Translation ]--- 0: 0xc0000000-0xc03fffff 0x00000000 4G Kernel x m 1: 0xc0400000-0xc05fffff 0x00400000 2G Kernel x m 2: 0xc0600000-0xc06fffff 0x00600000 1G Kernel x m 3: 0xc0700000-0xc077ffff 0x00700000 512M Kernel x m 4: 0xc0780000-0xc079ffff 0x00780000 128M Kernel x m 5: 0xc07a0000-0xc07bffff 0x007a0000 128M Kernel x m 6: - 7: - This is because pt_dump_size() expects a size in Kbytes but bat_show_603() gives the size in bytes. To avoid risk of confusion, change pt_dump_size() to take bytes.
