	The prstatus of an s390x dump contains several padding areas. Zero out these bytes to make reading the notes section easier with a hexdump. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>
2013-08-08	dump: rebase from host-private RAMBlock offsets to guest-physical addresses	Laszlo Ersek	1	-1/+2
	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>
2013-07-30	s390: Implement dump-guest-memory support for target s390x	Ekaterina Tumanova	1	-0/+212
	With this patch dump-guest-memory on s390 produces an ELF formatted, crash-readable dump. In order to implement this, the arch-specific part of dump-guest-memory was added: target-s390x/arch_dump.c contains the whole set of function for writing Elf note sections of all types for s390x.
