2015-07-09disas: QOMify target specific setupPeter Crosthwaite
Add a QOM function hook for target-specific disassembly setup. This allows removal of the #ifdeffery currently implementing target specific disas setup from disas.c.

2015-07-09disas: Add print_insn to disassemble infoPeter Crosthwaite
Add the print_insn pointer to the disassemble info structure. This is to prepare for QOMification support, where a QOM CPU hook function will be responsible for setting the print_insn() function. Add this function to the existing struct to consolidate such that only the one struct needs to be passed to the new QOM API.

2015-07-09cpu: Convert cpu_index into a bitmapBharata B Rao
Currently CPUState::cpu_index is monotonically increasing and a newly created CPU always gets the next higher index. The next available index is calculated by counting the existing number of CPUs. This is fine as long as we only add CPUs, but there are architectures which are starting to support CPU removal, too. For an architecture like PowerPC which derives its CPU identifier (device tree ID) from cpu_index, the existing logic of generating cpu_index values causes problems. With the currently proposed method of handling vCPU removal by parking the vCPU fd in QEMU (Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html), generating cpu_index this way will not work for PowerPC. This patch changes the way cpu_index is handed out by maintaining a bit map of the CPUs that tracks both addition and removal of CPUs. The CPU bitmap allocation logic is part of cpu_exec_init(), which is called by instance_init routines of various CPU targets. Newly added cpu_exec_exit() API handles the deallocation part and this routine is called from generic CPU instance_finalize. Note: This new CPU enumeration is for !CONFIG_USER_ONLY only. CONFIG_USER_ONLY continues to have the old enumeration logic.

Add an Error argument to cpu_exec_init() to let users collect the error. This is in preparation to change the CPU enumeration logic in cpu_exec_init(). With the new enumeration logic, cpu_exec_init() can fail if cpu_index values corresponding to max_cpus have already been handed out. Since all current callers of cpu_exec_init() are from instance_init, use error_abort Error argument to abort in case of an error.

2015-07-08ich9: implement strap SPKR pin logicPaulo Alcantara
If the signal is sampled high, this indicates that the system is strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system reboot feature). The status of this strap is readable via the NO_REBOOT bit (CC: offset 0x3410:bit 5). The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit may be set or cleared by software if the strap is sampled low but may not override the strap when it indicates "No Reboot". This patch implements the logic where hardware has ability to set SPKR pin through a property named "noreboot" and it's sampled high by default.

2015-07-07xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabledBharata B Rao
When supporting CPU hot removal by parking the vCPU fd and reusing it during hotplug again, there can be cases where we try to reenable KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled. Introduce a boolean member in ICPState to track this and don't reenable the CAP if it was already enabled earlier. Re-enabling this CAP should ideally work, but currently it results in kernel trying to create and associate ICP with this vCPU and that fails since there is already an ICP associated with it. Hence this patch is needed to work around this problem in the kernel. This change allows CPU hot removal to work for sPAPR.

The ram_limit field was imported from sPAPREnvironment where it predates the machine's ram size being available generically from machine->ram_size. Worse, the existing code was inconsistent about where it got the ram size from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size' and sometimes a local 'ram_size' masking the global. This cleans up the code to consistently use machine->ram_size, eliminating spapr->ram_limit in the process.

Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState.

The problem here is what happens if we start the target without -S and there happens one error during migration that puts current state as -EIO.

We need the names of RAMBlocks as they're loaded for RDMA, reuse a slightly modified ram_control_load_hook: a) Pass a 'data' parameter to use for the name in the block-reg case b) Only some hook types now require the presence of a hook function.

2015-07-07ich9: add TCO interface emulationPaulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

2015-07-07crypto: move built-in D3DES implementation into crypto/Daniel P. Berrange
To prepare for a generic internal cipher API, move the built-in D3DES implementation into the crypto/ directory. This is not in fact a normal D3DES implementation, it is D3DES with double & triple length modes removed, and the key bytes in reversed bit order. IOW it is crippled specifically for the "benefit" of RFB, so call the new files desrfb.c instead of d3des.c to make it clear that it isn't a generally useful impl. Signed-off-by: Daniel P.

2015-07-07crypto: introduce new module for computing hash digestsDaniel P. Berrange
Introduce a new crypto/ directory that will (eventually) contain all the cryptographic related code. This initially defines a wrapper for initializing gnutls and for computing hashes with gnutls. The former ensures that gnutls is guaranteed to be initialized exactly once in QEMU regardless of CLI args. The block quorum code currently fails to initialize gnutls so it only works by luck, if VNC server TLS is not requested. The hash APIs avoids the need to litter the rest of the code with preprocessor checks and simplifies callers by allocating the correct amount of memory for the requested hash.

2015-07-07vl: move rom_load_all after machine init doneEric Auger
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the memory preparation for boot until the machine init done notifier. This has for consequence to insert ROM at machine init done time. However the rom_load_all function stayed called before the ROM are inserted. As a consequence the rom_load_all function does not do everything it is expected to do, on ARM. It currently registers the ROM reset notifier but does not iterate through the registered ROM list. the isrom field is not set properly. This latter is used to report info in the monitor and also to decide whether the rom->data can be freed on ROM reset notifier. To fix that regression the patch moves the rom_load_all call after machine init done. We also take the opportunity to rename the rom_load_all function into rom_check_and_resgister_reset() and integrate the rom_load_done in it.

2015-07-06vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devicesGabriel Laupre
Fix pba_offset initialization value for Chelsio T5 Virtual Function device. The T5 hardware has a bug in it where it reports a Pending Interrupt Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead of the 0x1000 that the hardware actually uses internally. As the hardware doesn't return the correct pba_offset value, add a quirk to instead return a hardcoded value of 0x1000 when a Chelsio T5 VF device is detected. This bug has been fixed in the Chelsio's next chip series T6 but there are no plans to respin the T5 ASIC for this bug. It is just documented in the T5 Errata and left it at that.

2015-07-06hw/vfio/platform: add irqfd supportEric Auger
This patch aims at optimizing IRQ handling using irqfd framework. Instead of handling the eventfds on user-side they are handled on kernel side using - the KVM irqfd framework, - the VFIO driver virqfd framework. the virtual IRQ completion is trapped at interrupt controller This removes the need for fast/slow path swap. Overall this brings significant performance improvements.
