2018-03-12qom: introduce object_class_get_list_sortedPaolo Bonzini
Unify half a dozen copies of very similar code (the only difference being whether comparisons were case-sensitive) and use it also in Tricore, which did not do any sorting of CPU model names. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-10-27alpha: cleanup cpu type name compositionIgor Mammedov
Introduce ALPHA_CPU_TYPE_NAME macro to replace rather ununique TYPE macro that alpha uses. With new macro it will follow the same naming convention as other targets. While at it put scattered TypeInfo into one array which places type desriptions at one place and reduces code a bit.

2017-09-07target/alpha: Switch to do_transaction_failed() hookPeter Maydell
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 Mammedov
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().

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.
