2012-12-14e500: Adding CCSR memory regionBharat Bhushan1-23/+40
All devices are also placed under CCSR memory region. The CCSR memory region is exported to pci device. The MSI interrupt generation is the main reason to export the CCSR region to PCI device. This put the requirement to move mpic under CCSR region, but logically all devices should be under CCSR. So this patch places all emulated devices under ccsr region.

2012-12-14pseries: Implement PAPR NVRAMDavid Gibson4-1/+232
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>
2012-12-14pseries: Split xics irq configuration from state informationDavid Gibson1-12/+8
Currently the XICS irq controller code has a per-irq state structure which amongst other things includes whether the interrupt is level or message triggered - this is configured by the platform code, and is not directly visible to the guest. This leads to a slightly awkward construct at reset time where we need to reset everything in the state structure _except_ the lsi/msi flag, which needs to retain the information given at platform init time. More importantly this flag will make matching the qemu state to the KVM state for the upcoming in-kernel XICS implementation more awkward. This patch, therefore, removes this flag from the per-irq state structure, instead adding a parallel array giving the lsi/msi configuration per irq.

2012-12-14pseries: Allow RTAS tokens without a qemu handlerBen Herrenschmidt1-1/+1
Kernel-based RTAS calls will not have a qemu handler, but will still be registered in qemu in order to be assigned a token number and appear in the device-tree.

2012-12-14pseries: Return the token when we register an RTAS callMichael Ellerman2-3/+3
The kernel will soon be able to service some RTAS calls. However the choice of tokens will still be up to userspace. To support this have spapr_rtas_register() return the token that is allocated for an RTAS call, that allows the calling code to tell the kernel what the token value is.

2012-12-14pseries: Use #define for XICS base irq numberBen Herrenschmidt3-2/+3
Currently the lowest "real" irq number for the XICS irq controller (as opposed to numbers reserved for IPIs and other special purposes) is hard coded as 16 in two places - in xics_system_init() and in spapr.c. As well as being generally bad practice, we're going to need to change this number soon to fit in with the in-kernel XICS implementation. This patch adds a #define for this number to avoid future breakage.

2012-12-14pseries: Fix incorrect initialization of interrupt controllerDavid Gibson1-1/+1
Currently in the reset code for the XICS interrupt controller, we initialize the pending_priority field to 0 (most favored, by XICS convention). This is incorrect, since there is no pending interrupt, it should be set to least favored - 0xff. At the moment our XICS implementation doesn't get hurt by this edge case, but it does confuse the upcoming kernel XICS implementation.

Check for a 0 "distance" value to avoid infinite loop when the expired FCR timer was not programed with auto-increment. With this change the behavior is coherent with the same type of code in the exynos4210_gfrc_restart() function in the same file. Linux seems to mostly use this timer with auto-increment which explain why it is not a problem most of the time. However other OS might have a problem with this if they don't use the auto-increment feature.

commit 7b482bcf xilinx_zynq: added QSPI controller Adds one QSPI controller, which has two spi buses, one is for spi0, and another is for spi1.

The GIC architecture specification for v1 and v2 GICs (as found on the Cortex-A9 and newer) states that the GICC_PMR reset value is zero; this differs from the 0xf0 reset value used on 11MPCore. The NVIC is different again in not having a CPU interface; since we share the GIC code we must force the priority mask field to allow through all interrupts.

2012-12-11hw/arm_boot, exynos4210, highbank: Fix secondary boot GIC initPeter Maydell3-8/+26
Fix the code in the secondary CPU boot stubs so that it correctly initialises the GIC rather than relying on bugs or implementation dependent aspects of the QEMU GIC implementation: * set the GIC_PMR.Priority field to all-ones, so that all interrupts are passed through. The default of all-zeroes means all interrupts are masked, and QEMU only booted because of a bug in the priority masking in our GIC implementation. * add a barrier after GIC setup and before WFI to ensure that GIC config is complete before we go into a possible low power state. This isn't needed with the software GIC model but could be required when using KVM and executing this code on the real hardware CPU. Note that of the three secondary stub implementations, only the common generic one needs to support both v6 and v7 DSB encodings; highbank and exynos4210 will always be v7 CPUs.

2012-12-11Support default block interfaces per QEMUMachineChristian Borntraeger14-44/+30
There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a default/standard interface to their block devices / drives. Therefore, this patch introduces a new field default_block_type per QEMUMachine struct. The prior use_scsi field becomes thereby obsolete and is replaced through .default_block_type = IF_SCSI. This patch also changes the default for s390x to IF_VIRTIO and removes an early hack that converts IF_IDE drives. Other parties have already claimed interest (e.g. IF_SD for exynos) To create a sane default, for machines that dont specify a default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1. I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c) as well as IF_IDE and it seems that it is ok to change the defines - in other words, I found no obvious (to me) assumption in the code regarding IF_NONE==0. IF_NONE is only set if there is an explicit if=none. Without if=* the interface becomes IF_DEFAULT. I would suggest to have some additional care, e.g. by letting this patch sit some days in the block tree.

2012-12-11virtio-blk: Remove duplicate property definitionDavid Gibson2-2/+0
For the virtio-blk device (via virtio-pci) the property "config-wce" is defined in two places. First, it's defined from the DEFINE_VIRTIO_BLK_FEATURES macro, second it's defined directly in virtio-pci, just two lines above the call to that macro. The direct definition in virtio-pci.c is broken, since it operates on the 'config_wce' field of VirtIOBlkConf, which is never used anywhere else. Therefore, this patch removes both the extra property definition and the redundant field it works on.
