2022-10-26accel/tcg: Simplify page_get/alloc_target_dataRichard Henderson
Since the only user, Arm MTE, always requires allocation, merge the get and alloc functions to always produce a non-null result. Also assume that the user has already checked page validity.

2022-10-26accel/tcg: Call tb_invalidate_phys_page for PAGE_RESETRichard Henderson
When PAGE_RESET is set, we are replacing pages with new content, which means that we need to invalidate existing cached data, such as TranslationBlocks. Perform the reset invalidate while we're doing other invalidates, which allows us to remove the separate invalidates from the user-only mmap/munmap/mprotect routines. In addition, restrict invalidation to PAGE_EXEC pages. Since cdf713085131, we have validated PAGE_EXEC is present before translation, which means we can assume that if the bit is not present, there are no translations to invalidate.

2022-10-26accel/tcg: Add a quicker check for breakpointsLeandro Lupori
Profiling QEMU during Fedora 35 for PPC64 boot revealed that a considerable amount of time was being spent in check_for_breakpoints() (0.61% of total time on PPC64 and 2.19% on amd64), even though it was just checking that its queue was empty and returning, when no breakpoints were set. It turns out this function is not inlined by the compiler and it's always called by helper_lookup_tb_ptr(), one of the most called functions. By leaving only the check for empty queue in check_for_breakpoints() and moving the remaining code to check_for_breakpoints_slow(), called only when the queue is not empty, it's possible to avoid the call overhead. An improvement of about 3% in total time was measured on POWER9.

2022-10-25Revert "accel/tcg: Init TCG cflags in vCPU thread handler"Peter Maydell
Commit a82fd5a4ec24d was intended to be a code cleanup, but unfortunately it has a bug. It moves the initialization of the TCG cflags from the "start a new vcpu" function to the thread handler; this is fine when each vcpu has its own thread, but when we are doing round-robin of vcpus on a single thread we end up only initializing the cflags for CPU 0, not for any of the others. The most obvious effect of this bug is that running in icount mode with more than one CPU is broken; typically the guest hangs shortly after it brings up the secondary CPUs. This reverts commit a82fd5a4ec24d923ff1e6da128c0fd4a74079d99.

2022-10-25linux-user: Add guest memory layout to exception dumpHelge Deller
When the emulation stops with a hard exception it's very useful for debugging purposes to dump the current guest memory layout (for an example see /proc/self/maps) beside the CPU registers. The open_self_maps() function provides such a memory dump, but since it's located in the syscall.c file, various changes (add #includes, make this function externally visible, ...) are needed to be able to call it from the existing EXCP_DUMP() macro. This patch takes another approach by re-defining EXCP_DUMP() to call target_exception_dump(), which is in syscall.c, consolidates the log print functions and allows to add the call to dump the memory layout. Beside a reduced code footprint, this approach keeps the changes across the various callers minimal, and keeps EXCP_DUMP() highlighted as important macro/function.

2022-10-24ui: remove useless typecastsVolker Rümelin
Commit 8f9abdf586 ("chardev: src buffer const for write functions") changed the type of the second parameter of qemu_chr_be_write() from uint8_t * to const uint8_t *. Remove the now useless type casts from qemu_chr_be_write() function calls in ui/console.c and ui/gtk.c.

2022-10-24hw/mem/nvdimm: fix error message for 'unarmed' flagJulia Suvorova
In the ACPI specification [1], the 'unarmed' bit is set when a device cannot accept a persistent write. This means that when a memdev is read-only, the 'unarmed' flag must be turned on. The logic is correct, just changing the error message.
