2018-01-20target/ppc: add support for hypervisor doorbells on book3s CPUsCédric Le Goater
The hypervisor doorbells are used by skiboot and Linux on POWER9 processors to wake up secondaries. This adds processor control support to the Server architecture by reusing the Embedded support. They are very similar, only the bits definition of the CPU identifier differ. Still to be done is message broadcast to all threads of the same processor.

2017-04-26target/ppc: Flush TLB on write to PIDRSuraj Jitindar Singh
The PIDR (process id register) is used to store the id of the currently running process, which is used to select the process table entry used to perform address translation. This means that when we write to this register all the translations in the TLB become outdated as they are for a previously running process. Thus when this register is written to we need to invalidate the TLB entries to ensure stale entries aren't used to to perform translation for the new process, which would result in at best segfaults or alternatively just random memory being accessed.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
