2021-06-19tcg: Combine dh_is_64bit and dh_is_signed to dh_typecodeRichard Henderson2-45/+26
We will shortly be interested in distinguishing pointers from integers in the helper's declaration, as well as a true void return. We currently have two parallel 1 bit fields; merge them and expand to a 3 bit field. Our current maximum is 7 helper arguments, plus the return makes 8 * 3 = 24 bits used within the uint32_t typemask.

Currently the ARM SVE helper code defines locally some utility functions for swapping 16-bit halfwords within 32-bit or 64-bit values and for swapping 32-bit words within 64-bit values, parallel to the byte-swapping bswap16/32/64 functions. We want these also for the ARM MVE code, and they're potentially generally useful for other targets, so move them to bitops.h. (We don't put them in bswap.h with the bswap* functions because they are implemented in terms of the rotate operations also defined in bitops.h, and including bitops.h from bswap.h seems better avoided.)

2021-06-15hostmem: Wire up RAM_NORESERVE via "reserve" propertyDavid Hildenbrand1-1/+1
Let's provide a way to control the use of RAM_NORESERVE via memory backends using the "reserve" property which defaults to true (old behavior). Only Linux currently supports clearing the flag (and support is checked at runtime, depending on the setting of "/proc/sys/vm/overcommit_memory"). Windows and other POSIX systems will bail out with "reserve=false". The target use case is virtio-mem, which dynamically exposes memory inside a large, sparse memory area to the VM. This essentially allows avoiding to set "/proc/sys/vm/overcommit_memory == 0") when using virtio-mem and also supporting hugetlbfs in the future. As really only Linux implements RAM_NORESERVE right now, let's expose the property only with CONFIG_LINUX. Setting the property to "false" will then only fail in corner cases -- for example on very old kernels or when memory overcommit was completely disabled by the admin.

2021-06-15util/mmap-alloc: Support RAM_NORESERVE via MAP_NORESERVE under LinuxDavid Hildenbrand1-0/+3
Let's support RAM_NORESERVE via MAP_NORESERVE on Linux. The flag has no effect on most shared mappings - except for hugetlbfs and anonymous memory. Linux man page: "MAP_NORESERVE: Do not reserve swap space for this mapping. When swap space is reserved, one has the guarantee that it is possible to modify the mapping. When swap space is not reserved one might get SIGSEGV upon a write if no physical memory is available. See also the discussion of the file /proc/sys/vm/overcommit_memory in proc(5). In kernels before 2.6, this flag had effect only for private writable mappings." Note that the "guarantee" part is wrong with memory overcommit in Linux. Also, in Linux hugetlbfs is treated differently - we configure reservation of huge pages from the pool, not reservation of swap space (huge pages cannot be swapped). The rough behavior is [1]: a) !Hugetlbfs: 1) Without MAP_NORESERVE *or* with memory overcommit under Linux disabled ("/proc/sys/vm/overcommit_memory == 2"), the following accounting/reservation happens: For a file backed map SHARED or READ-only - 0 cost (the file is the map not swap) PRIVATE WRITABLE - size of mapping per instance For an anonymous or /dev/zero map SHARED - size of mapping PRIVATE READ-only - 0 cost (but of little use) PRIVATE WRITABLE - size of mapping per instance 2) With MAP_NORESERVE, no accounting/reservation happens. b) Hugetlbfs: 1) Without MAP_NORESERVE, huge pages are reserved. 2) With MAP_NORESERVE, no huge pages are reserved. Note: With "/proc/sys/vm/overcommit_memory == 0", we were already able to configure it for !hugetlbfs globally; this toggle now allows configuring it more fine-grained, not for the whole system. The target use case is virtio-mem, which dynamically exposes memory inside a large, sparse memory area to the VM.

2021-06-15memory: Introduce RAM_NORESERVE and wire it up in qemu_ram_mmap()David Hildenbrand4-5/+23
Let's introduce RAM_NORESERVE, allowing mmap'ing with MAP_NORESERVE. The new flag has the following semantics: " RAM is mmap-ed with MAP_NORESERVE. When set, reserving swap space (or huge pages if applicable) is skipped: will bail out if not supported. When not set, the OS will do the reservation, if supported for the memory type. " Allow passing it into: - memory_region_init_ram_nomigrate() - memory_region_init_resizeable_ram() - memory_region_init_ram_from_file() ... and teach qemu_ram_mmap() and qemu_anon_ram_alloc() about the flag. Bail out if the flag is not supported, which is the case right now for both, POSIX and win32. We will add Linux support next and allow specifying RAM_NORESERVE via memory backends.

Let's pass flags instead of bools to prepare for passing other flags and update the documentation of qemu_ram_mmap(). Introduce new QEMU_MAP_ flags that abstract the mmap() PROT_ and MAP_ flag handling and simplify it. We expose only flags that are currently supported by qemu_ram_mmap(). Maybe, we'll see qemu_mmap() in the future as well that can implement these flags. Note: We don't use MAP_ flags as some flags (e.g., MAP_SYNC) are only defined for some systems and we want to always be able to identify these flags reliably inside qemu_ram_mmap() -- for example, to properly warn when some future flags are not available or effective on a system. Also, this way we can simplify PROT_ handling as well.

2021-06-15softmmu/physmem: Fix ram_block_discard_range() to handle shared anonymous memoryDavid Hildenbrand1-2/+2
We can create shared anonymous memory via "-object memory-backend-ram,share=on,..." which is, for example, required by PVRDMA for mremap() to work. Shared anonymous memory is weird, though. Instead of MADV_DONTNEED, we have to use MADV_REMOVE: MADV_DONTNEED will only remove / zap all relevant page table entries of the current process, the backend storage will not get removed, resulting in no reduced memory consumption and a repopulation of previous content on next access. Shared anonymous memory is internally really just shmem, but without a fd exposed. As we cannot use fallocate() without the fd to discard the backing storage, MADV_REMOVE gets the same job done without a fd as documented in "man 2 madvise". Removing backing storage implicitly invalidates all page table entries with relevant mappings - an additional MADV_DONTNEED is not required.

2021-06-11tcg: Move in_code_gen_buffer and tests to region.cRichard Henderson1-10/+1
Shortly, the full code_gen_buffer will only be visible to region.c, so move in_code_gen_buffer out-of-line. Move the debugging versions of tcg_splitwx_to_{rx,rw} to region.c as well, so that the compiler gets to see the implementation of in_code_gen_buffer. This leaves exactly one use of in_code_gen_buffer outside of region.c, in cpu_restore_state. Which, being on the exception path, is not performance critical.

Long story short, we need a space here for the reference to work correctly. Longer story: Without the space, kerneldoc generates a line like this: one of :c:type:`MemoryListener.region_add\(\) <MemoryListener>`,:c:type:`MemoryListener.region_del\(\) Sphinx does not process the role information correctly, so we get this (my pseudo-notation) construct: <text>,:c:type:</text> <reference target="MemoryListener">MemoryListener.region_del()</reference> which does not reference the desired entity, and leaves some extra junk in the rendered output. See https://qemu-project.gitlab.io/qemu/devel/memory.html#c.MemoryListener member log_start for an example of the broken output as it looks today.

2021-06-04qemu-config: parse configuration files to a QDictPaolo Bonzini1-1/+6
Change the parser to put the values into a QDict and pass them to a callback. qemu_config_parse's QemuOpts creation is itself turned into a callback function. This is useful for -readconfig to support keyval-based options; getting a QDict from the parser removes a roundtrip from QDict to QemuOpts and then back to QDict. Unfortunately there is a disadvantage in that semantic errors will point to the last line of the group, because the entries of the QDict do not have a location attached.
