2018-07-09hw/timer/cmsdk-apb-timer: Correct ptimer policy settingsPeter Maydell
The CMSDK timer interrupt triggers when the counter goes from 1 to 0, so we want to trigger immediately, rather than waiting for a clock cycle. Drop the incorrect NO_IMMEDIATE_TRIGGER setting. We also do not want to get an interrupt if the guest sets the counter directly to zero, so use the new TRIGGER_ONLY_ON_DECREMENT policy.

2018-07-09ptimer: Add TRIGGER_ONLY_ON_DECREMENT policy optionPeter Maydell
The CMSDK timer behaviour is that an interrupt is triggered when the counter counts down from 1 to 0; however one is not triggered if the counter is manually set to 0 by a guest write to the counter register. Currently ptimer can't handle this; add a policy option to allow a ptimer user to request this behaviour.

2018-07-09hw/arm/smmu-common: Fix devfn computation in smmu_iommu_mrEric Auger
smmu_iommu_mr() aims at returning the IOMMUMemoryRegion corresponding to a given sid. The function extracts both the PCIe bus number and the devfn to return this data. Current computation of devfn is wrong as it only returns the PCIe function instead of slot | function.

2018-07-09sam460ex: Make sam460ex_load_device_tree() handle all errors internallyDavid Gibson
sam460ex_load_device_tree() handles nearly all possible errors by simply exiting (within helper functions and macros). It handles two early error cases by returning an error. There's no particular point to this, so make it handle those directly as well, removing the need for the caller to handle a failure. As a bonus it gives us more specific error messages.

2018-07-09sam460ex: Don't check for errors from qemu_fdt_*()David Gibson

2018-07-09sam460ex: Check for errors from libfdt functionsDavid Gibson
In a couple of places sam460ex_load_device_tree() calls "raw" libfdt functions which can fail, but doesn't check for error codes. At best, if these fail the guest will be silently started in a non-standard state, or it could fail entirely. Fix this by using the _FDT() helper macro which aborts on a libfdt failure.

Commit 29f9cef "ppc: Include vga cirrus card into the compiling process" changed the default display adapter for all PPC machines to cirrus. Unfortunately it missed setting the default display type to stdvga for both PReP machines causing the display to fail to initialise under OpenHackWare.

2018-07-03ehci: Don't fetch a NULL current qtd but advance the queue instead.Sebastian Bauer
Fetching qtd with the NULL address most likely makes no sense so from now on, we handle it this case similarly as if the terminate (T) bit is not set, which is already an exception as according to section 3.6 of the EHCI spec there is no T bit defined for the current_qtd field. The spec is a bit vague on how an EHCI driver should initialize these fields: "The general operational model is that the host controller can detect whether the overlay area contains a description of an active transfer" (p. 49). QEMU primarily uses the QTD_TOKEN_ACTIVE bit of the queue header to infer the activity state but there are other ways conceivable. This change allows QEMU to boot further into AmigaOS. The public available version of the EHCI driver recycles queue heads in some rare conditions but only clears the current_qtd field but not the status field. This works with many available EHCI PCI cards but e.g., not with the Freescale USB controller's found on the P5040. On the emulated EHCI controller of QEMU the consequence is that some garbage was read in, which resulted in a reset of the controller. This change fixes the problem.

2018-07-03ppc: Include vga cirrus card into the compiling processSebastian Bauer
Drivers for this card exists on PPC-based AmigaOS guests so it is useful to allow users to emulate the graphics card for PPC machines. As cirrus vga is currently preferred over std(vga) in absence of any user choice, this change also sets the default display of spapr machines to std as otherwise qemu refuses to start these machines. Not specifying an explicit graphics mode is for instance done by 'make check'. Signed-off-by: Sebastian Bauer <mail@sebastianbauer.info> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-07-03spapr: compute default value of "hpt-max-page-size" laterGreg Kurz
It is currently not possible to run a pseries-2.12 or older machine with HV KVM. QEMU prints the following and exits right away. qemu-system-ppc64: KVM doesn't support for base page shift 34 The "hpt-max-page-size" capability was recently added to spapr to hide host configuration details from HPT mode guests. Its default value for newer machine types is 64k. For backwards compatibility, pseries-2.12 and older machine types need a different value. This is handled as usual in a class init function. The default value is 16G, ie, all page sizes supported by POWER7 and newer CPUs, but HV KVM requires guest pages to be hpa contiguous as well as gpa contiguous. The default value is the page size used to back the guest RAM in this case. Unfortunately kvmppc_hpt_needs_host_contiguous_pages()->kvm_enabled() is called way before KVM init and returns false, even if the user requested KVM. We thus end up selecting 16G, which isn't supported by HV KVM. The default value must be set during machine init, because we can safely assume that KVM is initialized at this point. We fix this by moving the logic to default_caps_with_cpu(). Since the user cannot pass cap-hpt-max-page-size=0, we set the default to 0 in the pseries-2.12 class init function and use that as a flag to do the real work.

2018-07-03hw/ppc: Give sam46ex its own config optionDavid Gibson
At present the Sam460ex board is activated by the general CONFIG_PPC4XX option. However that includes the board for both ppc-softmmu and (deprecated) ppcemb-softmmu builds. As Sam460ex is developed, that would require adding more things into ppcemb-softmmu, which we don't want to do. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

commit d35aefa9ae15 ("ppc/pnv: introduce a new intc_create() operation to the chip model") changed the object link in the pnv_core_realize() routine but a return was forgotten in case of error, which can lead to more problems afterwards (segv) Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Greg Kurz <groug@kaod.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-07-03ppc/xics: rework the ICS classes inheritance treeCédric Le Goater
With the previous changes, we can now let the ICS_KVM class inherit directly from ICS_BASE class and not from the intermediate ICS_SIMPLE. It makes the class hierarchy much cleaner. What is left in the top classes is the low level interface to access the KVM XICS device in ICS_KVM and the XICS emulating handlers in ICS_SIMPLE. This should not break migration compatibility.
