The QEMU ELF loader does not zero the bss segment. This resulted in several bugs, e.g. see commit 5d739a4787a5 (s390-ccw.img: Fix sporadic errors with ccw boot image - initialize css) commit 6a40fa2669d3 (s390-ccw.img: Initialize next_idx) commit 8775d91a0f42 (pc-bios/s390-ccw: Fix problem with invalid virtio-scsi LUN when rebooting) Let's fix this once and forever by letting the BIOS zero the bss itself.

2017-12-14s390x/migration: use zero flag parameterChristian Borntraeger1-8/+8
valgrind pointed out that we call KVM_S390_GET_IRQ_STATE with an undefined value for flags. Kernels prior to 4.15 did not use that field, and later kernels ignore it for compatibility reasons, but we better play safe. The same is true for SET_IRQ_STATE. We should make sure to not use the flag field, either.

Provide HMP monitor command execution result as it would be seen by user who established an HMP monitor session. Currently many commands may silently fail without any sign of that. This patch let this info to be printed once test is running in verbose mode. For the future it might be useful to fail the test if command has failed, however it would require a bit of rework inside test engine itself. A simple example of silent failure without reporting it would to add some non-existent HMP command into 'hmp_cmds' list. In this case test will report it successfully passed without error.

2017-12-13target/arm: Provide fault type enum and FSR conversion functionsPeter Maydell1-0/+185
Currently get_phys_addr() and its various subfunctions return a hard-coded fault status register value for translation failures. This is awkward because FSR values these days may be either long-descriptor format or short-descriptor format. Worse, the right FSR type to use doesn't depend only on the translation table being walked -- some cases, like fault info reported to AArch32 EL2 for some kinds of ATS operation, must be in long-descriptor format even if the translation table being walked was short format. We can't get those cases right with our current approach. Provide fields in the ARMMMUFaultInfo struct which allow get_phys_addr() to provide sufficient information for a caller to construct an FSR value themselves, and utility functions which do this for both long and short format FSR values, as a first step in switching get_phys_addr() and its children to only returning the failure cause in the ARMMMUFaultInfo struct.

2017-12-13target/arm: Split M profile MNegPri mmu index into user and privPeter Maydell4-29/+50
For M profile, we currently have an mmu index MNegPri for "requested execution priority negative". This fails to distinguish "requested execution priority negative, privileged" from "requested execution priority negative, usermode", but the two can return different results for MPU lookups. Fix this by splitting MNegPri into MNegPriPriv and MNegPriUser, and similarly for the Secure equivalent MSNegPri. This takes us from 6 M profile MMU modes to 8, which means we need to bump NB_MMU_MODES; this is OK since the point where we are forced to reduce TLB sizes is 9 MMU modes. (It would in theory be possible to stick with 6 MMU indexes: {mpu-disabled,user,privileged} x {secure,nonsecure} since in the MPU-disabled case the result of an MPU lookup is always the same for both user and privileged code. However we would then need to rework the TB flags handling to put user/priv into the TB flags separately from the mmuidx. Adding an extra couple of mmu indexes is simpler.)

2017-12-13target/arm: Allow explicit writes to CONTROL.SPSEL in Handler modePeter Maydell1-1/+4
In ARMv7M the CPU ignores explicit writes to CONTROL.SPSEL in Handler mode. In v8M the behaviour is slightly different: writes to the bit are permitted but will have no effect. We've already done the hard work to handle the value in CONTROL.SPSEL being out of sync with what stack pointer is actually in use, so all we need to do to fix this last loose end is to update the condition we use to guard whether we call write_v7m_control_spsel() on the register write.

2017-12-13target/arm: Handle SPSEL and current stack being out of sync in MSP/PSP readsPeter Maydell1-6/+4
For v8M it is possible for the CONTROL.SPSEL bit value and the current stack to be out of sync. This means we need to update the checks used in reads and writes of the PSP and MSP special registers to use v7m_using_psp() rather than directly checking the SPSEL bit in the control register.

2017-12-13hw/intc/arm_gicv3_its: Implement full resetEric Auger1-1/+8
Voiding the ITS caches is not supposed to happen via individual register writes. So we introduced a dedicated ITS KVM device ioctl to perform a cold reset of the ITS: KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_ITS_CTRL_RESET. Let's use this latter if the kernel supports it.

2017-12-13hw/intc/arm_gicv3_its: Implement a minimalist resetEric Auger1-0/+42
At the moment the ITS is not properly reset and this causes various bugs on save/restore. We implement a minimalist reset through individual register writes but for kernel versions before v4.15 this fails voiding the vITS cache. We cannot claim we have a comprehensive reset (hence the error message) but that's better than nothing.
