2015-03-09pseries: Move sPAPR RTC code into its own fileDavid Gibson
At the moment the RTAS (firmware/hypervisor) time of day functions are implemented in spapr_rtas.c along with a bunch of other things. Since we're going to be expanding these a bit, move the RTAS RTC related code out into new file spapr_rtc.c. Also add its own initialization function, spapr_rtc_init() called from the main machine init routine.

2014-11-04target-ppc: virtex-ml507 machine type should depend on CONFIG_XILINXDavid Gibson
The virtex-ml507 is a Xilinx CPU based system, and requires several sub devices which are only included with CONFIG_XILINX. Therefore, it should only be compiled if CONFIG_XILINX is set.

2014-06-27spapr_pci_vfio: Add spapr-pci-vfio-host-bridge to support vfioAlexey Kardashevskiy
The patch adds a spapr-pci-vfio-host-bridge device type which is a PCI Host Bridge with VFIO support. The new device inherits from the spapr-pci-host-bridge device and adds an "iommu" property which is an IOMMU id. This ID represents a minimal entity for which IOMMU isolation can be guaranteed. In SPAPR architecture IOMMU group is called a Partitionable Endpoint (PE). Current implementation supports one IOMMU id per QEMU VFIO PHB. Since SPAPR allows multiple PHB for no extra cost, this does not seem to be a problem. This limitation may change in the future though. Example of use: Configure and Add 3 functions of a multifunctional device to QEMU: (the NEC PCI USB card is used as an example here): -device spapr-pci-vfio-host-bridge,id=USB,iommu=4,index=7 \ -device vfio-pci,host=4:0:1.0,addr=1.0,bus=USB,multifunction=true -device vfio-pci,host=4:0:1.1,addr=1.1,bus=USB -device vfio-pci,host=4:0:1.2,addr=1.2,bus=USB where: * index=7 is a QEMU PHB index (used as source for MMIO/MSI/IO windows offset); * iommu=4 is an IOMMU id which can be found in sysfs: [aik@vpl2 ~]$ cd /sys/bus/pci/devices/0004:00:00.0/ [aik@vpl2 0004:00:00.0]$ ls -l iommu_group lrwxrwxrwx 1 root root 0 Jun 5 12:49 iommu_group -> ../../../kernel/iommu_groups/4 Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>

2012-12-14pseries: Implement PAPR NVRAMDavid Gibson
The PAPR specification requires a certain amount of NVRAM, accessed via RTAS, which we don't currently implement in qemu. This patch addresses this deficiency, implementing the NVRAM as a VIO device, with some glue to instantiate it automatically based on a machine option. The machine option specifies a drive id, which is used to back the NVRAM, making it persistent. If nothing is specified, the driver instead simply allocates space for the NVRAM, which will not be persistent Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-10-29pseries: Implement qemu initiated shutdowns using EPOW eventsDavid Gibson
At present, using 'system_powerdown' from the monitor or otherwise instructing qemu to (cleanly) shut down a pseries guest will not work, because we did not have a method of signalling the shutdown request to the guest. PAPR does include a usable mechanism for this, though it is rather more involved than the equivalent on x86. This involves sending an EPOW (Environmental and POwer Warning) event through the PAPR event and error logging mechanism, which also has a number of other functions. This patch implements just enough of the event/error logging functionality to be able to send a shutdown event to the guest. At least with modern guest kernels and a userspace that is up and running, this means that system_powerdown from the qemu monitor should now work correctly on pseries guests.

2012-08-15PPC: e500: add generic e500 platformScott Wood
This gives the kernel a paravirtualized machine to target, without requiring both sides to pretend to be targeting a specific board that likely has little to do with the host in KVM scenarios. This avoids the need to add new boards to QEMU, just to be able to run KVM on new CPUs.

2012-06-27pseries: Convert sPAPR TCEs to use generic IOMMU infrastructureDavid Gibson
The pseries platform already contains an IOMMU implementation, since it is essential for the platform's paravirtualized VIO devices. This IOMMU support is currently built into the implementation of the VIO "bus" and the various VIO devices. This patch converts this code to make use of the new common IOMMU infrastructure. We don't yet handle synchronization of map/unmap callbacks vs. invalidations, this will require some complex interaction with the kernel and is not a major concern at this stage.

2012-06-24PPC: e500: require libfdtAlexander Graf
Now that we're moving all of the device tree generation from an external pre-execution generated blob to runtime generation using libfdt, we absolutely must have libfdt around. This requirement was there before already, as the only way to not require libfdt with e500 was to not use -kernel, which was the only way to boot the mpc8544ds machine. This patch only manifests said requirement in the build system. Signed-off-by: Alexander Graf <agraf@suse.de>
