2017-09-07target/alpha: Switch to do_transaction_failed() hookPeter Maydell4-13/+24
Switch the alpha target from the old unassigned_access hook to the new do_transaction_failed hook. This allows us to resolve a ??? in the old hook implementation. The only part of the alpha target that does physical memory accesses is reading the page table -- add a TODO comment there to the effect that we should handle bus faults on page table walks. (Since the palcode doesn't actually do anything useful on a bus fault anyway it's a bit moot for now.)

2017-09-01alpha: replace cpu_alpha_init() with cpu_generic_init()Igor Mammedov2-18/+6
cpu_alpha_init() used to provide default fallback if invalid (i.e. non existent) cpu_model were provided. dp264 machine provides its own default so sole user of fallback is [bsd|linux]-user targets which specifies 'any' cpu model that fallbacks to "ev67" in cpu_alpha_init(). Push fallback handling into alpha_cpu_class_by_name() and replace cpu_alpha_init() with cpu_generic_init().

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake1-2/+2
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth15-0/+6101
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.
