docs: s390: convert docs to ReST and rename to *.rst

2019-06-11T07:48:14+00:00

Convert all text files with s390 documentation to ReST format. Tried to preserve as much as possible the original document format. Still, some of the files required some work in order for it to be visible on both plain text and after converted to html. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Heiko Carstens

s390/zcore: remove /sys/kernel/debug/zcore/mem

2015-11-27T08:24:12+00:00

New versions of the SCSI dumper use the /dev/vmcore interface instead of zcore mem. Remove the outdated interface. Acked-by: Michael Holzheu Signed-off-by: Martin Schwidefsky

s390/zfcpdump: Update documentation in zfcpdump.txt

2014-05-20T06:58:44+00:00

Do the following changes: - Document new /proc/vmcore interface - Document partition dump external initramfs with s390-tools-1.24.0 - Remove initramfs config file because initramfs is now built automatically in s390-tools - Replace description of kernel config options with "make zfcpdump_defconfig" - Some editorial changes Signed-off-by: Michael Holzheu Signed-off-by: Martin Schwidefsky

s390/dump: Remove CONFIG_ZFCPDUMP

2014-05-20T06:58:43+00:00

Currently there are two s390 kernel dump config options "CONFIG_ZFCPDUMP" and "CONFIG_CRASH_DUMP". In order to keep things simple and because the "CONFIG_ZFCPDUMP" option already has a dependency to "CONFIG_CRASH_DUMP" remove the CONFIG_ZFCPDUMP option.

[S390] zfcpdump support.

2007-04-27T14:01:44+00:00

s390 machines provide hardware support for creating Linux dumps on SCSI disks. For creating a dump a special purpose dump Linux is used. The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux. This patch exports memory and registers of the crashed Linux to userspace via a debugfs file. For more information refer to Documentation/s390/zfcpdump.txt, which is included in this patch.
