2014-02-27s390x/sclp: Add missing checks to SCLP handlerThomas Huth1-1/+1
If the 51 most significant bits of the SCCB address are zero or equal to the prefix, we should throw an specification exception, too. Also moved the check for privileged mode to sclp_service_call() to have all program checks in one place now.

2013-09-20s390/ebcdic: Move conversion tables to header fileHeinz Graalfs1-80/+1
Move conversion tables to header file. - In SCLP line mode processing EBCDIC/ASCII conversion is needed. - An additional EBCDIC to ASCII conversion function is added.

2013-09-20s390/kexec: Implement diag308 subcode 0Christian Borntraeger1-0/+26
This patch implements subcode 0 of diag 308. This is necessary for kexec (without kdump). The main difference to subcode 1 is that all CPUs get a full reset, instead of the architectured CPU reset (which leaves all registers untouched). Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>
2013-09-03cpu: Use QTAILQ for CPU listAndreas Färber1-4/+4
Introduce CPU_FOREACH(), CPU_FOREACH_SAFE() and CPU_NEXT() shorthand macros. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-08-30s390: Implement load normal resetChristian Borntraeger1-0/+30
kdump on s390 uses a load normal reset to bring the system in a defined state by doing a subsystem reset. The issuing CPUs will have an initial CPU reset, all other CPUs will have a CPU reset as defined in POP (no register content will change). Implement this as architectured.

2013-08-30s390/kvm: basic implementation of diagnose 308 subcode 6Eugene (jno) Dvurechenski1-0/+40
Linux uses a check for subcode 6 to decide if other subcodes are available. Provide a minimal implementation for subcode 6, as well as for subcode 5.

2013-01-18s390x: Remove inline function ebcdic_put and related data from cpu.hStefan Weil1-0/+81
The function is only used in misc_helper.c, so move it to that file. This reduces the size of debug executables (compiled without optimization) because they get unused code and data for each compilation which includes cpu.h. Executables with optimization don't change their size. ebcdic2ascii is currently unused and could be removed (not done here). The array ascii2ebcdic must be accessed with an unsigned index, therefore (int)ascii[i] was replaced by (uint8_t)ascii[i]. The old code would have failed for a signed char less than 0. The current code only converts "QEMU" and spaces to EBCDIC, so there is no problem today. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Alexander Graf <agraf@suse.de>

Make the user path more like the system path. Prepare for more kinds of runtime exceptions. Rename ILC to ILEN to make it clear that we want to pass around a full instruction length, rather than a "code" that happens to be stored one bit left in a larger field.

2012-10-29s390: sclp base supportHeinz Graalfs1-44/+1
This adds a more generic infrastructure for handling Service-Call requests on s390. Currently we only support a small subset of Read SCP Info directly in target-s390x. This patch provides the base infrastructure for supporting more commands and moves Read SCP Info. In the future we could add additional commands for hotplug, call home and event handling.
