2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

2019-06-12Normalize position of header guardMarkus Armbruster
This is the common header guard idiom: /* * File comment */ #ifndef GUARD_SYMBOL_H #define GUARD_SYMBOL_H ... actual contents ... #endif A few of our headers have some #include before the guard. target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard. A few more have the #define elsewhere. Change them to match the common idiom. For spr_def_64.h, that means dropping #ifndef __DOXYGEN__. While there, rename guard symbols to make scripts/clean-header-guards.pl happy.

2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster
CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2019-01-11avoid TABs in files that only contain a fewPaolo Bonzini
Most files that have TABs only contain a handful of them. Change them to spaces so that we don't confuse people. disas, standard-headers, linux-headers and libdecnumber are imported from other projects and probably should be exempted from the check. Outside those, after this patch the following files still contain both 8-space and TAB sequences at the beginning of the line.

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.

Convert all existing readers of tb->cflags to tb_cflags, so that we use atomic_read and therefore avoid undefined behaviour in C11. Note that the remaining setters/getters of the field are protected by tb_lock, and therefore do not need conversion. Luckily all readers access the field via 'tb->cflags' (so no foo.cflags, bar->cflags in the code base), which makes the conversion easily scriptable: FILES=$(git grep 'tb->cflags' target include/exec/gen-icount.h \ accel/tcg/translator.c | cut -f1 -d':' | sort | uniq) perl -pi -e 's/([^.>])tb->cflags/$1tb_cflags(tb)/g' $FILES perl -pi -e 's/([a-z->.]*)(->|\.)tb->cflags/tb_cflags($1$2tb)/g' $FILES Then manually fixed the few errors that checkpatch reported.

2017-01-13qom/cpu: move tlb_flush to cpu_common_resetAlex Bennée
It is a common thing amongst the various cpu reset functions want to flush the SoftMMU's TLB entries. This is done either by calling tlb_flush directly or by way of a general memset of the CPU structure (sometimes both). This moves the tlb_flush call to the common reset function and additionally ensures it is only done for the CONFIG_SOFTMMU case and when tcg is enabled. In some target cases we add an empty end_of_reset_fields structure to the target vCPU structure so have a clear end point for any memset which is resetting value in the structure before CPU_COMMON (where the TLB structures are). While this is a nice clean-up in general it is also a precursor for changes coming to cputlb for MTTCG where the clearing of entries can't be done arbitrarily across vCPUs. Currently the cpu_reset function is usually called from the context of another vCPU as the architectural power up sequence is run. By using the cputlb API functions we can ensure the right behaviour in the future.

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.
