2015-10-23openpic: add to misc categoryLaurent Vivier
openpic is a programmable interrupt controller, so add it to the misc category. Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2015-06-22qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster
These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

2015-03-09openpic: fix up loadvm under -M mac99Mark Cave-Ayland
Issuing loadvm under -M mac99 would fail for two reasons: firstly an incorrect version number for openpic would cause openpic_load() to abort, and secondly a cut/paste error when restoring the IVPR and IDR registers caused subsequent vmstate sections to become misaligned and abort early.

2014-06-16openpic: Reset IRQ source private membersPaul Janzen
The openpic emulation code maintains an allowable-CPU's bitmap ("destmask") for each IRQ source which is calculated from the IDR register value whenever the guest OS writes to it. However, if the guest OS relies on the system to set the IDR register to a default value at reset, and does not write IDR, then destmask does not get updated, and interrupts do not get propagated to the guest. Additionally, if an IRQ source is marked as critical, the source's internal "output" and "nomask" fields are not correctly reset when the PIC is reset. Fix both these issues by calling write_IRQreg_idr from within openpic_reset, instead of simply setting the IDR register to the specified idr_reset value.

2014-06-16openpic: Move definition of openpic_resetPaul Janzen
This patch moves the definition of openpic_reset after the various register read/write functions. No functional change. It is in preparation for using the register read/write functions in openpic_reset. Signed-off-by: Paul Janzen <pcj@pauljanzen.org> Signed-off-by: Alexander Graf <agraf@suse.de>

2014-05-05openpic: avoid buffer overrun on incoming migrationMichael Roth
CVE-2013-4534 opp->nb_cpus is read from the wire and used to determine how many IRQDest elements to read into opp->dst[]. If the value exceeds the length of opp->dst[], MAX_CPU, opp->dst[] can be overrun with arbitrary data from the wire. Fix this by failing migration if the value read from the wire exceeds MAX_CPU.

Since current_cpu is CPUState it no longer depends on CPUPPCState. Move ppce500_set_mpic_proxy() to a new hw/ppc/ppc_e500.h because hw/ppc/ppc.h is too heavily using CPUPPCState and PowerPCCPU. Signed-off-by: Andreas Färber <afaerber@suse.de>
