* s390x: cleanup interrupt injectionCornelia Huck2014-06-101-1/+6
| | | | | | | Remove the need for a cpu to inject a floating interrupt on kvm. Acked-by: Thomas Huth <thuth@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
* s390x/kvm: enable/reset cmma via vm attributesDominik Dingel2014-06-101-0/+2
| | | | | | | | | | | | | | | | | | | Exploit the new api for userspace-controlled cmma. If supported, enable cmma during kvm initialization and register a reset handler for cmma, which is also called directly from the load IPL code. The reset functionality is needed to reset the cmma state of the guest pages, e.g. if a system reset is triggered via qemu monitor; otherwise this could result in data corruption. A guest triggered reboot may now lead to multiple cmma resets; this is OK, however, as this is slowpath anyway and the simplest way to achieve the intended effects.

* softmmu: introduce cpu_ldst.hPaolo Bonzini2014-06-051-1/+1
| | | | | | | | | | This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch.

* tcg: Invert the inclusion of helper.hRichard Henderson2014-05-281-1/+1
| | | | | | | | | | Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
* misc: Use cpu_physical_memory_read and cpu_physical_memory_writeStefan Weil2014-04-271-6/+6

| | | | | | | | | | | 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.

* s390/kexec: Implement diag308 subcode 0Christian Borntraeger2013-09-201-0/+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).

* s390: Implement load normal resetChristian Borntraeger2013-08-301-0/+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.

* s390x: Remove inline function ebcdic_put and related data from cpu.hStefan Weil2013-01-181-0/+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>
