Today we're hardcoding the PCI interrupt map in the e500 machine file. Instead, let's write it dynamically so that different machine types can have different slot properties. Signed-off-by: NAlexander Graf <agraf@suse.de>

The IRQ line calculation is more or less hardcoded today. Instead, let's write it as an algorithmic function that theoretically allows an arbitrary number of PCI slots. Signed-off-by: NAlexander Graf <agraf@suse.de>

When we're done with one interrupt, we need to search for the next pending interrupt in the queue. This search has grown quite big now that we have more than 256 possible irq lines. So let's memorize how many interrupts we have pending in our bitmaps, so that we can always bail out in the usual case - the one where we're all done. Signed-off-by: NAlexander Graf <agraf@suse.de>

This patch converts the OpenPIC device to qdev. Along the way it renames the "openpic" target to "raven" and the "mpic" target to "fsl_mpic_20", to better reflect the actual models they implement. This way we have a generic OpenPIC device now that can handle different flavors of the OpenPIC specification. Signed-off-by: NAlexander Graf <agraf@suse.de>

The openpic code has its own bitmap code to access bits inside of a bitmap. However, that is overkill when we simply want to check for a bit inside of a uint32_t. So instead, let's use normal bit masks and C builtin shifts and ands. Signed-off-by: NAlexander Graf <agraf@suse.de>

MPIC interrupt numbers in Linux (device tree) and in QEMU are different, because QEMU takes the sparseness of the IRQ number space into account. Remove that cleverness and instead assume a flat number space. This makes the code easier to understand, because we are actually aligned with Linux on the view of our worlds.

PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.

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.

Now that we have implemented PAPR compatible NVRAM interfaces in qemu, this updates the SLOF firmware to actually initialize and use the NVRAM as a PAPR guest firmware is expected to do. This SLOF update also includes an ugly but useful workaround for a bug in the SLES11 installer which caused it to fail under KVM.

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: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NAlexander Graf <agraf@suse.de>

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.

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.

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.

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.

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.
