2014-11-04PPC: E500: Instantiate MPC8XXX gpio controller on virt machineAlexander Graf
With the e500 virt machine, we don't have to adhere to the exact hardware layout of an mpc8544ds board. So there we can just add a qoriq compatible GPIO controller into the system that we can add a power off hook to. Signed-off-by: Alexander Graf <agraf@suse.de>

2014-11-04spapr: Cleanup machine naming conventions, and prepare for 2.2 releaseDavid Gibson
As of qemu-2.1, spapr/pseries, has a set of versioned machine classes to represent the machine type as it appeared to the guest in different qemu versions. This allows for safe migration of guests between current and future qemu versions. However, these are organized a bit differently from those for PC: on PC, the default plain "pc" machine type is just an alias for the most recent versioned machine type. In sPAPR, it names the base machine class from which the versioned types are derived. The PC approach is preferable; it makes it clearer which explicit version is the current one. Additionally updating the "current" machine as the base class makes it even more likely than otherwise to incorrectly alter the versioned machines' behaviour when updating the current machine. Therefore this patch changes sPAPR to the PC approach - the base class becomes abstract, and plain "pseries" becomes an alias for the most recent versioned machine class. Since qemu-2.1 is now released, we also create a new pseries-2.2 machine type, to incorporate changes during this development cycle (for now it is identical to pseries-2.1).

Such address translation is needed when load address recorded in uImage is a virtual address. When the actual load address is requested, return untranslated address: user that needs the translated address can always apply translation function to it and those that need it untranslated don't need to do the inverse translation.

2014-11-02virtio-pci: fix migration for pci bus masterMichael S. Tsirkin
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out this code, and replace it: - Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG so just drop it for latest machine type. - For compat machine types, set PCI_COMMAND if DRIVER_OK is set. As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h to a new common header. Cc: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Michael S.

2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster
Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member.

2014-10-03ide: Update ide_drive_get to be HBA agnosticJohn Snow
Instead of duplicating the logic for the if_ide (bus,unit) mappings, rely on the blockdev layer for managing those mappings for us, and use the drive_get_by_index call instead. This allows ide_drive_get to work for AHCI HBAs as well, and can be used in the Q35 initialization. Lastly, change the nature of the argument to ide_drive_get so that represents the number of total drives we can support, and not the total number of buses. This will prevent array overflows if the units-per-default-bus property ever needs to be adjusted for compatibility reasons.

2014-09-08spapr_pci: map the MSI window in each PHBGreg Kurz
On sPAPR, virtio devices are connected to the PCI bus and use MSI-X. Commit cc943c36faa192cd4b32af8fe5edb31894017d35 has modified MSI-X so that writes are made using the bus master address space and follow the IOMMU path. Unfortunately, the IOMMU address space address space does not have an MSI window: the notification is silently dropped in unassigned_mem_write instead of reaching the guest... The most visible effect is that all virtio devices are non-functional on sPAPR since then. :( This patch does the following: 1) map the MSI window into the IOMMU address space for each PHB - since each PHB instantiates its own IOMMU address space, we can safely map the window at a fixed address (SPAPR_PCI_MSI_WINDOW) - no real need to keep the MSI window setup in a separate function, the spapr_pci_msi_init() code moves to spapr_phb_realize(). 2) kill the global MSI window as it is not needed in the end Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>

If this happened on a device which does not support MSI (but does support MSIX, otherwise "ibm,change-msi" would not be called), this device would have PCIDevice::msi_cap field (MSI capability offset) set to zero and writing a vector would actually clear PCI status.

2014-09-08PPC: Cuda: Use cuda timer to expose tbfreq to guestAlexander Graf
Mac OS X calibrates a number of frequencies on bootup based on reading tb values on bootup and comparing them to via cuda timer values. The only variable we can really steer well (thanks to KVM) is the cuda frequency. So let's use that one to fake Mac OS X into believing the bus frequency is tbfreq * 4. That way Mac OS X will automatically calculate the correct timebase frequency. With this patch and the patch set I posted earlier I can successfully run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

2014-09-08spapr: Locate RTAS and device-tree based on real RMABenjamin Herrenschmidt
We currently calculate the final RTAS and FDT location based on the early estimate of the RMA size, cropped to 256M on KVM since we only know the real RMA size at reset time which happens much later in the boot process. This means the FDT and RTAS end up right below 256M while they could be much higher, using precious RMA space and limiting what the OS bootloader can put there which has proved to be a problem with some OSes (such as when using very large initrd's) Fortunately, we do the actual copy of the device-tree into guest memory much later, during reset, late enough to be able to do it using the final RMA value, we just need to move the calculation to the right place. However, RTAS is still loaded too early, so we change the code to load the tiny blob into qemu memory early on, and then copy it into guest memory at reset time. It's small enough that the memory usage doesn't matter.

2014-09-08PPC: mac99: Move NVRAM to page boundary when necessaryAlexander Graf
When running KVM we have to adhere to host page boundaries for memory slots. Unfortunately the NVRAM on mac99 is a 4k RAM hole inside of an MMIO flash area. So if our host is configured with 64k page size, we can't use the mac99 target with KVM. This is a real shame, as this limitation is not really an issue - we can easily map NVRAM somewhere else and at least Linux and Mac OS X use it at their new location. So in that emergency case when it's about failing to run at all and moving NVRAM to a place it shouldn't be at, choose the latter. This patch enables -M mac99 with KVM on 64k page size hosts.

2014-09-08PPC: KVM: Fix g3beige and mac99 when HV is loadedAlexander Graf
On PPC we have 2 different styles of KVM: PR and HV. HV can only virtualize sPAPR guests while PR can virtualize everything that's reasonably close to the host hardware platform. As long as only one kernel module (PR or HV) is loaded, the "default" kvm type is the module that's loaded. So if your hardware only supports PR mode you can easily spawn a Mac VM. However, if both HV and PR are loaded we default to HV mode. And in that case the Mac machines have to explicitly ask for PR mode to get a working VM. Fix this up by explicitly having the Mac machines ask for PR style KVM. This fixes bootup of Mac VMs on systems where bot HV and PR kvm modules are loaded for me.

This implements an NMI interface POWERPC SPAPR machine. This enables an "nmi" HMP/QMP command supported on SPAPR. This calls POWERPC_EXCP_RESET (vector 0x100) in the guest to deliver NMI to every CPU. The expected result is XMON (in-kernel debugger) invocation.

2014-07-22ppc: fix -mem-path failureHu Tao
commit e938ba0c tried to enable -mem-path for ppc but breaked some ppc boards. The problems are: 1. it fails when allocating memory for rom, sram whose sizes are less than huge page size: ./ppc-softmmu/qemu-system-ppc -m 512 -mem-path /hugepages/ \ -kernel /home/hutao/Downloads/vmlinux-ppc -initrd \ /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed. 2. if there is a numa node backed by memory backend object, qemu fails with message: ./ppc-softmmu/qemu-system-ppc -m 512 \ -object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \ -numa node,nodeid=0,memdev=f0 \ -kernel /home/hutao/Downloads/vmlinux-ppc \ -initrd /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value. This patch does following: 1. replaces memory_region_allocate_system_memory() with memory_region_init_ram() for rom, sram. Then only system memory is backed by hugepages when specifying mem-path. 2. for memory banks, allocates all ram with one memory_region_allocate_system_memory(), and use memory_region_init_alias() to initialize memory banks.

2014-07-15spapr: Enable use of huge pagesAlexey Kardashevskiy
0b183fc87 "memory: move mem_path handling to memory_region_allocate_system_memory" disabled -mempath use for all machines that do not use memory_region_allocate_system_memory() to register RAM. Since SPAPR uses memory_region_init_ram(), the huge pages support was disabled for it. This replaces memory_region_init_ram()+vmstate_register_ram_global() with memory_region_allocate_system_memory() to get huge pages back. This changes RAM size from (ram_limit - rma_alloc_size) to ram_limit as the previous patch moved RMA memory region allocation after RAM allocation and therefore this change does not have immediate effect but simplifies the code.

2014-07-15spapr: Move RMA memory region registration codeAlexey Kardashevskiy
PPC970 does not support VRMA (virtual RMA) so real memory required for SLOF to execute must be allocated by the KVM_ALLOCATE_RMA ioctl. Later this memory is used as a part of the guest RAM area. The RMA allocating code also registers a memory region for this piece of RAM. We are going to simplify memory regions layout: RMA memory region will be a subregion in the RAM memory region, both starting from zero. This way we will not have to take care of start address alignment for the piece of RAM next to the RMA. This moves memory region business closer to the RAM memory region creation/allocation code. As this is a mechanical patch, no change in behaviour is expected.

memory_region_allocate_system_memory Commit 0b183fc871:"memory: move mem_path handling to memory_region_allocate_system_memory" split memory_region_init_ram and memory_region_init_ram_from_file. Also it moved mem-path handling a step up from memory_region_init_ram to memory_region_allocate_system_memory. Therefore for any board that uses memory_region_init_ram directly, -mem-path is not supported. Fix this by replacing memory_region_init_ram with memory_region_allocate_system_memory.
