* semihosting: Move include/hw/semihosting/ -> include/semihosting/Philippe Mathieu-Daudé2021-03-101-1/+1
| | | | | | | | | | | | | | We want to move the semihosting code out of hw/ in the next patch. This patch contains the mechanical steps, created using: $ git mv include/hw/semihosting/ include/ $ sed -i s,hw/semihosting,semihosting, $(git grep -l hw/semihosting) Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210226131356.3964782-2-f4bug@amsat.org> Message-Id: <20210305135451.15427-2-alex.bennee@linaro.org>
* semihosting: move semihosting configuration into its own directoryAlex Bennée2019-05-281-1/+1
| | | | | | | | | | | | In preparation for having some more common semihosting code let's excise the current config magic from vl.c into its own file. We shall later add more conditionals to the build configurations so we can avoid building this if we don't need it.

* tcg: Use CPUClass::tlb_fill in cputlb.cRichard Henderson2019-05-101-6/+0Star
| | | | | | | | | | | | We can now use the CPUClass hook instead of a named function. Create a static tlb_fill function to avoid other changes within cputlb.c. This also isolates the asserts within. Remove the named tlb_fill function from all of the targets.

* qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster2019-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | 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 *.

* Include qapi/error.h exactly where neededMarkus Armbruster2018-02-091-1/+0Star
| | | | | | | | | | | | | | This cleanup makes the number of objects depending on qapi/error.h drop from 1910 (out of 4743) to 1612 in my "build everything" tree. While there, separate #include from file comment with a blank line, and drop a useless comment on why qemu/osdep.h is included first.

* accel/tcg: add size paremeter in tlb_fill()Laurent Vivier2018-01-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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).
