2018-06-04linux-user: SPARC "rd %tick" can be used by user applicationLaurent Vivier
we have the same problem decribed in 7d6b1daedd ("linux-user, ppc: mftbl can be used by user application") for ppc in the case of sparc. When we use an application trying to resolve a name, it hangs in 0x00000000ff5dd40c: rd %tick, %o5 0x00000000ff5dd410: srlx %o5, 0x20, %o4 0x00000000ff5dd414: btst %o5, %g4 0x00000000ff5dd418: be %icc, 0xff5dd40c because %tick is staying at 0.

Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well.

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).

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.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
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.

2017-03-09sparc/sparc64: grab BQL before calling cpu_check_irqsAlex Bennée
IRQ modification is part of device emulation and should be done while the BQL is held to prevent races when MTTCG is enabled. This adds assertions in the hw emulation layer and wraps the calls from helpers in the BQL.

2017-02-24cputlb and arm/sparc targets: convert mmuidx flushes from varg to bitmapAlex Bennée
While the vargs approach was flexible the original MTTCG ended up having munge the bits to a bitmap so the data could be used in deferred work helpers. Instead of hiding that in cputlb we push the change to the API to make it take a bitmap of MMU indexes instead. For ARM some the resulting flushes end up being quite long so to aid readability I've tended to move the index shifting to a new line so all the bits being or-ed together line up nicely, for example: tlb_flush_page_by_mmuidx(other_cs, pageaddr, (1 << ARMMMUIdx_S1SE1) | (1 << ARMMMUIdx_S1SE0)); Signed-off-by: Alex Bennée <alex.bennee@linaro.org> [AT: SPARC parts only] Reviewed-by: Artyom Tarasenko <atar4qemu@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net> [PM: ARM parts only] Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
2017-02-21monitor: Fix crashes when using HMP commands without CPUThomas Huth
When running certain HMP commands ("info registers", "info cpustats", "info tlb", "nmi", "memsave" or dumping virtual memory) with the "none" machine, QEMU crashes with a segmentation fault. This happens because the "none" machine does not have any CPUs by default, but these HMP commands did not check for a valid CPU pointer yet. Add such checks now, so we get an error message about the missing CPU instead.
