2019-08-21spapr/pci: Free MSIs during resetGreg Kurz
When the machine is reset, the MSI bitmap is cleared but the allocated MSIs are not freed. Some operating systems, such as AIX, can detect the previous configuration and assert. Empty the MSI cache, this performs the needed cleanup.

2019-08-21spapr/pci: Consolidate de-allocation of MSIsGreg Kurz
When freeing MSIs, we need to: - remove them from the machine's MSI bitmap - remove them from the IC backend - remove them from the PHB's MSI cache This is currently open coded in two places in rtas_ibm_change_msi(), and we're about to need this in spapr_phb_reset() as well. Instead of duplicating this code again, make it a destroy function for the PHB's MSI cache. Removing an MSI device from the cache will call the destroy function internally.

2019-08-21spapr: Implement ibm,suspend-meNicholas Piggin
This has been useful to modify and test the Linux pseries suspend code but it requires modification to the guest to call it (due to being gated by other unimplemented features). It is not otherwise used by Linux yet, but work is slowly progressing there. This allows a (lightly modified) guest kernel to suspend with `echo mem > /sys/power/state` and be resumed with system_wakeup monitor command.

2019-08-21ppc/xive: Provide silent escalation supportCédric Le Goater
When the 's' bit is set the escalation is said to be 'silent' or 'silent/gather'. In such configuration, the notification sequence is skipped and only the escalation sequence is performed. This is used to configure all the EQs of a vCPU to escalate on a single EQ which will then target the hypervisor.

2019-08-21ppc/xive: Provide escalation supportCédric Le Goater
If the XIVE presenter can not find the NVT dispatched on any of the HW threads, it can not deliver the interrupt. XIVE offers an escalation mechanism to handle such scenarios and inform the hypervisor that an action should be taken. Escalation is configured by setting the 'e' bit and the EAS in word 4 & 5 to let the HW look for the escalation END on which to trigger a new event.

2019-08-21ppc/xive: Implement TM_PULL_OS_CTX special commandCédric Le Goater
When a vCPU is not dispatched anymore on a HW thread, the Hypervisor (KVM on Linux) invalidates the OS interrupt context of a vCPU with this special command. It returns the OS CAM line value and resets the VO bit.

2019-08-21spapr: initial implementation for H_TPM_COMM/spapr-tpm-proxyMichael Roth
This implements the H_TPM_COMM hypercall, which is used by an Ultravisor to pass TPM commands directly to the host's TPM device, or a TPM Resource Manager associated with the device. This also introduces a new virtual device, spapr-tpm-proxy, which is used to configure the host TPM path to be used to service requests sent by H_TPM_COMM hcalls, for example: -device spapr-tpm-proxy,id=tpmp0,host-path=/dev/tpmrm0 By default, no spapr-tpm-proxy will be created, and hcalls will return H_FUNCTION. The full specification for this hypercall can be found in docs/specs/ppc-spapr-uv-hcalls.txt Since SVM-related hcalls like H_TPM_COMM use a reserved range of 0xEF00-0xEF80, we introduce a separate hcall table here to handle them.

2019-08-21migration: Do not re-read the clock on pre_save in case of paused guestMaxiwell S. Garcia
Re-read the timebase before migrate was ported from x86 commit: 6053a86fe7bd: kvmclock: reduce kvmclock difference on migration The clock move makes the guest knows about the paused time between the stop and migrate commands. This is an issue in an already-paused VM because some side effects, like process stalls, could happen after migration. So, this patch checks the runstate of guest in the pre_save handler and do not re-reads the timebase in case of paused state (cold migration). Signed-off-by: Maxiwell S.

2019-08-16Set ENET_BD_BDU in I.MX FEC controllerAaron Hill
This commit properly sets the ENET_BD_BDU flag once the emulated FEC controller has finished processing the last descriptor. This is done for both transmit and receive descriptors. This allows the QNX 7.0.0 BSP for the Sabrelite board (which can be found at http://blackberry.qnx.com/en/developers/bsp) to properly control the FEC. Without this patch, the BSP ethernet driver will never re-use FEC descriptors, as the unset ENET_BD_BDU flag will cause it to believe that the descriptors are still in use by the NIC. Note that Linux does not appear to use this field at all, and is unaffected by this patch. Without this patch, QNX will think that the NIC is still processing its transaction descriptors, and won't send any more data over the network. For reference: On page 1192 of the I.MX 6DQ reference manual revision (Rev. 5, 06/2018), which can be found at https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-6-processors/i.mx-6quad-processors-high-performance-3d-graphics-hd-video-arm-cortex-a9-core:i.MX6Q?&tab=Documentation_Tab&linkline=Application-Note the 'BDU' field is described as follows for the 'Enhanced transmit buffer descriptor': 'Last buffer descriptor update done. Indicates that the last BD data has been updated by uDMA. This field is written by the user (=0) and uDMA (=1).' The same description is used for the receive buffer descriptor.

2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-08-16sysemu: Move the VMChangeStateEntry typedef to qemu/typedefs.hMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 1800 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous commit). Several headers include sysemu/sysemu.h just to get typedef VMChangeStateEntry. Move it from sysemu/sysemu.h to qemu/typedefs.h. Spell its structure tag the same while there. Drop the now superfluous includes of sysemu/sysemu.h from headers. Touching sysemu/sysemu.h now recompiles some 1100 objects. qemu/uuid.h also drops from 1800 to 1100, and qapi/qapi-types-run-state.h from 5000 to 4400.

2019-08-16Include sysemu/sysemu.h a lot lessMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/qdev-core.h includes sysemu/sysemu.h since recent commit e965ffa70a "qdev: add qdev_add_vm_change_state_handler()". This is a bad idea: hw/qdev-core.h is widely included. Move the declaration of qdev_add_vm_change_state_handler() to sysemu/sysemu.h, and drop the problematic include from hw/qdev-core.h. Touching sysemu/sysemu.h now recompiles some 1800 objects. qemu/uuid.h also drops from 5400 to 1800. A few more headers show smaller improvement: qemu/notify.h drops from 5600 to 5200, qemu/timer.h from 5600 to 4500, and qapi/qapi-types-run-state.h from 5500 to 5000.

2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.
