2018-05-04uninorth: create new uninorth deviceMark Cave-Ayland
Commit 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" added a TODO which was to convert the uninorth registers hack to a proper device. Move these registers to a new uninorth device, removing the old hacks from mac_newworld.c.

2018-05-04spapr: Clean up handling of LPCR power-saving exit bitsDavid Gibson
To prevent spurious wakeups on cpus that are supposed to be disabled, we need to clear the LPCR bits which control certain wakeup events. spapr_cpu_reset() has separate cases here for boot and non-boot (initially inactive) cpus. rtas_start_cpu() then turns the LPCR bits on when the non-boot cpus are activated. But explicit checks against first_cpu are not how we usually do things: instead spapr_cpu_reset() generally sets things up for non-boot (inactive) cpus, then spapr_machine_reset() and/or rtas_start_cpu() override as necessary. So, do that instead. Because the LPCR activation is identical for boot cpus and non-boot cpus just activated with rtas_start_cpu() we can put the code common in spapr_cpu_set_entry_state().

2018-05-04spapr: Move PAPR mode cpu setup fully to spapr codeDavid Gibson
cpu_ppc_set_papr() does several things: 1) it sets up the virtual hypervisor interface 2) it prevents the cpu from ever entering hypervisor mode 3) it tells KVM that we're emulating a cpu in PAPR mode and 4) it configures the LPCR and AMOR (hypervisor privileged registers) so that TCG will behave correctly for PAPR guests, without attempting to emulate the cpu in hypervisor mode (1) & (2) make sense for any virtual hypervisor (if another one ever exists). (3) belongs more properly in the machine type specific to a PAPR guest, so move it to spapr_cpu_init(). While we're at it, remove an ugly test on kvm_enabled() by making kvmppc_set_papr() a safe no-op on non-KVM. (4) also belongs more properly in the machine type specific code. (4) is done by mangling the default values of the SPRs, so that they will be set correctly at reset time. Manipulating usually-static parameters of the cpu model like this is kind of ugly, especially since the values used really have more to do with the platform than the cpu. The spapr code already has places for PAPR specific initializations of register state in spapr_cpu_reset(), so move this handling there.

2018-05-04target/ppc: Delay initialization of LPCR_UPRT for secondary cpusDavid Gibson
In cpu_ppc_set_papr() the UPRT and GTSE bits of the LPCR default value are initialized based on on ppc64_radix_guest(). Which seems reasonable, except that ppc64_radix_guest() is based on spapr->patb_entry which is only set up in spapr_machine_reset, called _after_ cpu_ppc_set_papr() for boot cpus. Well, and the fact that modifying the SPR default value for an instance rather than a class is kind of yucky. The initialization here is really only necessary or valid for hotplugged cpus; the base cpu initialization already sets a value that's good enough for the boot cpus until the guest uses an hcall to configure it's preferred MMU mode. So, move this initialization to the rtas_start_cpu() path, at which point ppc64_radix_guest() will have a sensible value, to make sure secondary cpus come up in an MMU mode matching the existing cpus.

2018-05-04spapr: Clean up LPCR updates from hypercallsDavid Gibson
There are several places in spapr_hcall.c where we need to update the LPCR value on all CPUs. We do this with the set_spr() helper. That's not really correct because this directly sets the SPR value, without going through the ppc_store_lpcr() helper which may need to update state based on the LPCR change. In fact, set_spr() is only ever used for the LPCR, so replace it with an explicit LPCR updated which uses the right low-level helper. While we're there, move the CPU_FOREACH() which was in every one of the callers into the new helper: set_all_lpcrs().

2018-05-04spapr: Make a helper to set up cpu entry point stateDavid Gibson
Under PAPR, only the boot CPU is active when the system starts. Other cpus must be explicitly activated using an RTAS call. The entry state for the boot and secondary cpus isn't identical, but it has some things in common. We're going to add a bit more common setup later, too, so to simplify make a helper which sets up the common entry state for both boot and secondary cpu threads.

2018-05-04spapr: Remove unhelpful helpers from rtas_start_cpu()David Gibson
rtas_start_cpu() calls spapr_cpu_update_tb_offset() and spapr_cpu_set_endianness() to initialize certain things in the new cpu's state. This is the only caller of those helpers, and they're each only a few lines long, so we might as well just fold them into the caller. In addition, those helpers initialize state on the new cpu to match that of the first cpu. That will generally work, but might be at least logically incorrect if the first cpu has been set offline by the guest. So, instead base the state on that of the cpu invoking the RTAS call, which is obviously active already.

2018-05-04spapr: Remove support for explicitly allocated RMAsDavid Gibson
Current POWER cpus allow for a VRMA, a special mapping which describes a guest's view of memory when in real mode (MMU off, from the guest's point of view). Older cpus didn't have that which meant that to support a guest a special host-contiguous region of memory was needed to give the guest its Real Mode Area (RMA). KVM used to provide special calls to allocate a contiguous RMA for those cases. This was useful in the early days of KVM on Power to allow it to be tested on PowerPC 970 chips as used in Macintosh G5 machines. Now, those machines are so old as to be almost irrelevant. The normal qemu deprecation process would require this to be marked deprecated then removed in 2 releases. However, this can only be used with corresponding support in the host kernel - which was dropped years ago (in c17b98cf "KVM: PPC: Book3S HV: Remove code for PPC970 processors" of 2014-12-03 to be precise). Therefore it should be ok to drop this immediately. Just to be clear this only affects *KVM HV* guests with PowerPC 970, and those already require an ancient host kernel. TCG and KVM PR guests with PowerPC 970 should still work. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Thomas Huth <thuth@redhat.com>

2018-04-27uninorth: introduce temporary pic_irqs device propertyMark Cave-Ayland
This is in preparation for moving the PCI bus wiring inside the uninorth host bridge devices. In the future it will be possible to remove this once the PICs have been switched to use qdev GPIOs.

2018-04-27uninorth: move PCI mmio memory region initialisation into init functionMark Cave-Ayland
Whilst we are here, rename the memory regions to better reflect whether they belong to either a PCI or an AGP bus. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-04-27mac_oldworld: move wiring of macio IRQs to macio_oldworld_realize()Mark Cave-Ayland
Since the macio device has a link to the PIC device, we can now wire up the IRQs directly via qdev GPIOs rather than having to use an intermediate array. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-04-27mac_oldworld: remove pics IRQ array and wire up macio to heathrow directlyMark Cave-Ayland

2018-04-27grackle: general tidy-up and QOMifyMark Cave-Ayland
This is the first step towards removing the old-style pci_grackle_init() function. Following on from the previous commit we can now pass the heathrow device as an object link and wire up the heathrow IRQs via qdev GPIOs.
