2014-11-27qemu-timer: Avoid overflows when converting timeout to struct timespecPeter Maydell
In qemu_poll_ns(), when we convert an int64_t nanosecond timeout into a struct timespec, we may accidentally run into overflow problems if the timeout is very long. This happens because the tv_sec field is a time_t, which is signed, so we might end up setting it to a negative value by mistake. This will result in what was intended to be a near-infinite timeout turning into an instantaneous timeout, and we'll busy loop. Cap the maximum timeout at INT32_MAX seconds (about 68 years) to avoid this problem. This specifically manifested on ARM hosts as an extreme slowdown on guest shutdown (when the guest reprogrammed the PL031 RTC to not generate alarms using a very long timeout) but could happen on other hosts and guests too.

2014-11-24pc: count in 1Gb hugepage alignment when sizing hotplug-memory containerIgor Mammedov
if DIMMs with different size/alignment are interleaved in creation order, it could lead to hotplug-memory container fragmentation and following inability to use all RAM upto maxmem. For example: -m 4G,slots=3,maxmem=7G -object memory-backend-file,id=mem-1,size=256M,mem-path=/pagesize-2MB -device pc-dimm,id=mem1,memdev=mem-1 -object memory-backend-file,id=mem-2,size=1G,mem-path=/pagesize-1GB -device pc-dimm,id=mem2,memdev=mem-2 -object memory-backend-file,id=mem-3,size=256M,mem-path=/pagesize-2MB -device pc-dimm,id=mem3,memdev=mem-3 fragments hotplug-memory container and doesn't allow to use 1GB hugepage backend to consume remainig 1Gb.

2014-11-24apic: fix incorrect handling of ExtINT interrupts wrt processor priorityPaolo Bonzini
This fixes another failure with ExtINT, demonstrated by QNX. The failure mode is as follows: - IPI sent to cpu 0 (bit set in APIC irr) - IPI accepted by cpu 0 (bit cleared in irr, set in isr) - IPI sent to cpu 0 (bit set in both irr and isr) - PIC interrupt sent to cpu 0 The PIC interrupt causes CPU_INTERRUPT_HARD to be set, but apic_irq_pending observes that the highest pending APIC interrupt priority (the IPI) is the same as the processor priority (since the IPI is still being handled), so apic_get_interrupt returns a spurious interrupt rather than the pending PIC interrupt. The result is an endless sequence of spurious interrupts, since nothing will clear CPU_INTERRUPT_HARD. Instead, ExtINT interrupts should have ignored the processor priority. Calling apic_check_pic early in apic_get_interrupt ensures that apic_deliver_pic_intr is called instead of delivering the spurious interrupt. apic_deliver_pic_intr then clears CPU_INTERRUPT_HARD if needed.

2014-11-24apic: fix loss of IPI due to masked ExtINTPaolo Bonzini
This patch fixes an obscure failure of the QNX kernel on QEMU x86 SMP. In QNX, all hardware interrupts come via the PIC, and are delivered by the cpu 0 LAPIC in ExtINT mode, while IPIs are delivered by the LAPIC in fixed mode. This bug happens as follows: - cpu 0 masks a particular PIC interrupt - IPI sent to cpu 0 (CPU_INTERRUPT_HARD is set) - before the IPI is accepted, the masked interrupt line is asserted by the device Since the interrupt is masked, apic_deliver_pic_intr will clear CPU_INTERRUPT_HARD. The IPI will still be set in the APIC irr, but since CPU_INTERRUPT_HARD is not set the cpu will not notice. Depending on the scenario this can cause a system hang, i.e. if cpu 0 is expected to unmask the interrupt. In order to fix this, do a full check of the APIC before an EXTINT is acknowledged. This can result in clearing CPU_INTERRUPT_HARD, but can also result in delivering the lost IPI.

2014-11-24apic: avoid getting out of halted state on masked PIC interruptsPaolo Bonzini
After the next patch, if a masked PIC interrupts causes CPU_INTERRUPT_POLL to be set, the CPU will spuriously get out of halted state. While this is technically valid, we should avoid that. Make CPU_INTERRUPT_POLL run apic_update_irq in the right thread and then look at CPU_INTERRUPT_HARD. If CPU_INTERRUPT_HARD does not get set, do not report the CPU as having work. Also move the handling of software-disabled APIC from apic_update_irq to apic_irq_pending, and always trigger CPU_INTERRUPT_POLL. This will be important once we will add a case that resets CPU_INTERRUPT_HARD from apic_update_irq. We want to run it even if we go through CPU_INTERRUPT_POLL, and even if the local APIC is software disabled.

The main reason for reverting this commit before the 2.2 release is that it adds a QAPI interface that we don't want to keep: The 'nocow' flag doesn't generally make sense for block nodes, but only for the raw-posix driver. It should therefore be part of ImageInfoSpecific rather than ImageInfo. The commit contains more problems, but unlike the API stability issue they wouldn't justify reverting it.

into staging Patch queue for ppc - 2014-11-20 Hopefully the last few fixups for 2.2: - KVM memory slot fix (should usually only occur on PPC) - e300 fix - Altivec mtvscr instruction fix # gpg: Signature made Thu 20 Nov 2014 13:53:34 GMT using RSA key ID 03FEDC60 # gpg: Good signature from "Alexander Graf <agraf@suse.de>" # gpg: aka "Alexander Graf <alex@csgraf.de>" * remotes/agraf/tags/signed-ppc-for-upstream: target-ppc: Altivec's mtvscr Decodes Wrong Register kvm: Fix memory slot page alignment logic target-ppc: Fix breakpoint registers for e300 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2014-11-20target-ppc: Altivec's mtvscr Decodes Wrong RegisterTom Musta
The Move to Vector Status and Control Register (mtvscr) instruction uses VRB as the source register. Fix the code generator to correctly decode the VRB field. That is, use "rB(ctx->opcode)" instead of "rD(ctx->opcode)". Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-20kvm: Fix memory slot page alignment logicAlexander Graf
Memory slots have to be page aligned to get entered into KVM. There is existing logic that tries to ensure that we pad memory slots that are not page aligned to the biggest region that would still fit in the alignment requirements. Unfortunately, that logic is broken. It tries to calculate the start offset based on the region size. Fix up the logic to do the thing it was intended to do and document it properly in the comment above it. With this patch applied, I can successfully run an e500 guest with more than 3GB RAM (at which point RAM starts overlapping subpage memory regions).

staging Fix from a while back that unfortunately got ignored.
