dump: rebase from host-private RAMBlock offsets to guest-physical addresses
RAMBlock.offset --> GuestPhysBlock.target_start RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end RAMBlock.length --> GuestPhysBlock.target_end - GuestPhysBlock.target_start "GuestPhysBlock.host_addr" is only used when writing the dump contents. This patch enables "crash" to work with the vmcore by rebasing the vmcore from the left side of the following diagram to the right side: host-private offset relative to ram_addr RAMBlock guest-visible paddrs 0 +-------------------+.....+-------------------+ 0 | ^ | | ^ | | 640 KB | | 640 KB | | v | | v | 0x0000a0000 +-------------------+.....+-------------------+ 0x0000a0000 | ^ | |XXXXXXXXXXXXXXXXXXX| | 384 KB | |XXXXXXXXXXXXXXXXXXX| | v | |XXXXXXXXXXXXXXXXXXX| 0x000100000 +-------------------+.....+-------------------+ 0x000100000 | ^ | | ^ | | 3583 MB | | 3583 MB | | v | | v | 0x0e0000000 +-------------------+.....+-------------------+ 0x0e0000000 | ^ |. |XXXXXXXXXXXXXXXXXXX| | above_4g_mem_size | . |XXXX PCI hole XXXXX| | v | . |XXXX XXXXX| ram_size +-------------------+ . |XXXX 512 MB XXXXX| . .|XXXXXXXXXXXXXXXXXXX| . +-------------------+ 0x100000000 . | ^ | . | above_4g_mem_size | .| v | +-------------------+ ram_size + 512 MB Related RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=981582 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
