2018-01-25accel/tcg: add size paremeter in tlb_fill()Laurent Vivier
The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

2018-01-09target/sparc: remove MemoryRegionSection check code from ↵Jean-Christophe Dubois
sparc_cpu_get_phys_page_debug() This code is preventing the MMU debug code from displaying virtual mappings of IO devices (anything that is not located in the RAM). Before this patch, Qemu would output 0xffffffffffffffff (-1) as the physical address corresponding to an IO device virtual address. With this patch the intended physical address is displayed.

2017-11-07linux-user/sparc: Put address for data faults where linux-user expects itPeter Maydell
In the user-mode-only version of sparc_cpu_handle_mmu_fault(), we must save the fault address for a data fault into the CPU state's mmu registers, because the code in linux-user/main.c expects to find it there in order to populate the si_addr field of the guest siginfo.

2017-09-01sparc: embed sparc_def_t into CPUSPARCStateIgor Mammedov
Make CPUSPARCState::def embedded so it would be allocated as part of cpu instance and we won't have to worry about cleaning def pointer up mannualy on cpu destruction.

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.
