The current allocator returns IRQ numbers from a pool and does not support IRQs reuse in any form as it did not keep track of what it previously returned, it only keeps the last returned IRQ. Some use cases such as PCI hot(un)plug may require IRQ release and reallocation. This moves an allocator from SPAPR to XICS. This switches IRQ users to use new API. This uses LSI/MSI flags to know if interrupt is allocated. The interrupt release function will be posted as a separate patch.

The existing interrupt allocation scheme in SPAPR assumes that interrupts are allocated at the start time, continously and the config will not change. However, there are cases when this is not going to work such as: 1. migration - we will have to have an ability to choose interrupt numbers for devices in the command line and this will create gaps in interrupt space. 2. PCI hotplug - interrupts from unplugged device need to be returned back to interrupt pool, otherwise we will quickly run out of interrupts. This replaces a separate lslsi[] array with a byte in the ICSIRQState struct and defines "LSI" and "MSI" flags. Neither of these flags set signals that the descriptor is not allocated and not in use.

At the moment spapr_rtas_register() allocates a new token number for every new RTAS callback so numbers are not fixed and depend on the number of supported RTAS handlers and the exact order of spapr_rtas_register() calls. These tokens are copied into the device tree and remain the same during the guest lifetime. When we start another guest to receive a migration, it calls spapr_rtas_register() as well. If the number of RTAS handlers or their order is different in QEMU on source and destination sides, the "/rtas" node in the device tree will differ. Since migration overwrites the device tree (as it overwrites the entire RAM), the actual RTAS config on the destination side gets broken. This defines global contant values for every RTAS token which QEMU is using today. This changes spapr_rtas_register() to accept a token number instead of allocating one. This changes all users of spapr_rtas_register(). This changes XICS-KVM not to cache tokens registered with KVM as they constant now. This makes TOKEN_BASE global as RTAS_XXX use TOKEN_BASE as a base. TOKEN_MAX is moved and renamed too and its value is changed to the last token + 1. Boundary checks for token values are adjusted. This reserves token numbers for "os-term" handlers and PCI hotplug which we are working on. Signed-off-by: NAlexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: NAlexander Graf <agraf@suse.de>

When we trigger a system reset, the in-kernel openpic controller should also get reset. This happens through a write to the GCR.RESET register which is the same mechanism a guest would use to manually reset the device. Signed-off-by: NAlexander Graf <agraf@suse.de>

由 Paul Janzen 提交于
The openpic emulation code maintains an allowable-CPU's bitmap ("destmask") for each IRQ source which is calculated from the IDR register value whenever the guest OS writes to it. However, if the guest OS relies on the system to set the IDR register to a default value at reset, and does not write IDR, then destmask does not get updated, and interrupts do not get propagated to the guest. Additionally, if an IRQ source is marked as critical, the source's internal "output" and "nomask" fields are not correctly reset when the PIC is reset. Fix both these issues by calling write_IRQreg_idr from within openpic_reset, instead of simply setting the IDR register to the specified idr_reset value.

Using error_is_set(ERRP) to find out whether a function failed is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f06). I guess the error_is_set(errp) in the DeviceClass realize() methods are merely fragile right now, because I can't find a call chain that passes a null errp argument. Make the code more robust and more obviously correct: receive the error in a local variable, then propagate it through the parameter.
