2012-10-29s390: sclp base supportHeinz Graalfs
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.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-09-10target-s390x: switch to AREG0 free modeBlue Swirl
Add an explicit CPUState parameter instead of relying on AREG0. Remove temporary wrappers and switch to AREG0 free mode. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> [agraf: fix conflicts] Signed-off-by: Alexander Graf <agraf@suse.de>
2012-09-10target-s390x: avoid AREG0 for FPU helpersBlue Swirl
Make FPU helpers take a parameter for CPUState instead of relying on global env. Introduce temporary wrappers for FPU load and store ops. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>

2012-08-15s390: provide interface for service interrupt/introduce interrupt.cChristian Borntraeger
This patch creates interrupt.c. The first user is a callback for hw/* code to trigger an service interrupt for a given sccb value. Several interrupt types for s390 are floating (can be delivered to all CPUs). so this code does not belong to a specific CPU. Other interrupts (like the virtio one) are also floating and can be moved here later on. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>

2011-11-14s390x: Add shutdown for TCG s390-virtio machineAlexander Graf
Now that we have code in place to do refcounting of online CPUs, we can drag the TCG code along and implement shutdown for that one too, so it doesn't feel left out by its KVM counterpart. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-11-14s390: Fix cpu shutdown for KVMChristian Borntraeger
On s390 a shutdown is the state of all CPUs being either stopped or disabled (for interrupts) waiting. We have to track the overall number of running CPUs to call the shutdown sequence accordingly. This patch implements the counting and shutdown handling for the kvm path in qemu. Lets also wrap changes to env->halted and env->exception_index.

2011-11-14s390x: update R and C bits in storage keyAlexander Graf
When the s390x maps a page or writes happen to a page, the R and C bits get updated. The easiest way to implement this in qemu is to simply update them whenever we map a TLB translation and act according to the permissions. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-09-03Use new macro QEMU_PACKED for packed structuresStefan Weil
Most changes were made using these commands: git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__((__packed__))'|xargs perl -pi -e 's/__attribute__\(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((__packed__))'|xargs perl -pi -e 's/__attribute__ \(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute((packed))'|xargs perl -pi -e 's/__attribute\(\(packed\)\)/QEMU_PACKED/' Whitespace in linux-user/syscall_defs.h was fixed manually to avoid warnings from scripts/checkpatch.pl. Manual changes were also applied to hw/pc.c. I did not fix indentation with tabs in block/vvfat.c. The patch will show 4 errors with scripts/checkpatch.pl.

2011-08-07Remove unused is_softmmu parameter from cpu_handle_mmu_faultBlue Swirl
Parameter is_softmmu (and its evil mutant twin brother is_softmuu) is not used in cpu_*_handle_mmu_fault() functions, remove them and adjust callers. Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26Move cpu_has_work and cpu_pc_from_tb to cpu.hBlue Swirl
Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is needed by later patches. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-20Switch build system to accompanied kernel headersJan Kiszka
This helps reducing our build-time checks for feature support in the available Linux kernel headers. And it helps users that do not have sufficiently recent headers installed on their build machine. Consequently, the patch removes and build-time checks for kvm and vhost in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are supposed to be provided by QEMU only. s390 needs some extra love as it carries redefinitions from kernel headers.

2011-05-20s390x: remove compatibility cc fieldAlexander Graf
Remove the now unused cc field that was only required to not break bisectability. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20s390x: Shift variables in CPUState for memset(0)Alexander Graf
The default reset handler does a memset(0) until right in between CPU_COMMON. I incorrectly changed that behavior on the s390x port, so let's move the fields in CPUState around to reflect the correct split up to which point memset(0) zeros out everything. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20s390x: keep hint on virtio managing sizeAlexander Graf
The s390x virtio bus keeps management information on virtio after the top of the guest's RAM. We need to be able to tell the guest the size of its RAM (without virtio stuff), but also be able to trap when the guest accesses RAM outside of its scope (including virtio stuff). So we need a variable telling us the size of the virtio stuff, so we can calculate the highest available RAM address from that. While at it, also increase the maximum number of virtio pages, so we play along well with more recent kernels that spawn a ridiculous number of virtio console adapters. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20s390x: make kvm exported functions conditional on kvmAlexander Graf
We have some helper functions we use to directly invoke KVM functionality from device emulation code. This patch replaces those exported functions with static inline stubs when not building with KVM enabled. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-04-18s390x: Prepare cpu.h for emulationAlexander Graf
We need to add some more logic to the CPU description to leverage emulation of an s390x CPU. This patch adds all the required helpers, fields in CPUState and constant definitions required for user and system emulation.

2009-12-05S/390 CPU fake emulationAlexander Graf
Because Qemu currently requires a TCG target to exist and there are quite some useful helpers here to lay the groundwork for out KVM target, let's create a stub TCG emulation target for S390X CPUs. This is required to make tcg happy. The emulation target itself won't work though. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
