[PATCH v28 0/8] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) 25 Jun '24

25 Jun '24

This MR adds support for creating file mapping objects backed by large pages on Linux, by making the following changes: ## wineserver * On Linux, `create_temp_file` will first attempt to use memfds as the backing fd. If it fails, it'll return to the current codepath, creating a temporary file in either the server or config directory. * The created memfd will be sealed against writes, if the caller requesting the appropriate page protection flags. * This removes the requirement that FDs be only created on filesystems/directories that aren't `noexec`. * In the server method `create_mapping` , if large pages have been requested by the caller, hold that the calling thread's token holds `SeLockMemoryPrivilege` . * Additionally, add `SeLockMemoryPrivilege` to the list of privileges enabled for the Administrator. ## `ntdll` * Add `virtual_get_min_large_page_size` and its exported wrapper `wine_unix_get_min_large_page_size`. * On Linux, the minimum page size is determined by going through `/sys/kernel/mm/hugepages`. If hugepage support was not detected, `STATUS_NOT_SUPPORTED` is returned instead. On other platforms, the older hard-coded value of 2\*1024\*1024 is returned instead. * `NtCreateSection` will validate certain parameters if large pages are requested. Specifically, it will return STATUS_INVALID_PARAMETER if the requested mapping is not anonymous/unnamed, or the size is not a multiple of the minimum supported page size. ## `kernelbase` * `GetLargePageMinimum` will use `wine_unix_get_min_large_page_size`. ## `kernel32/tests` * Add new test test_large_page_file_mapping, which validates privilege enforcements and parameter validation while creating large pages backed file mapping obejcts. The tests are skipped if `GetLargePageMinimum` returns 0. -- v28: psapi: Add tests for querying information for large pages. ntdll: Use PAGEMAP_SCAN ioctl to implement get_working_set_ex, if available. kernel32: Add tests for large pages support. ntdll: Support allocating virtual memory, creating and mapping files backed by large pages (SEC_LARGE_PAGES, MEM_LARGE_PAGES). https://gitlab.winehq.org/wine/wine/-/merge_requests/5769

[PATCH v2 0/3] MR5915: include: Tweak atexit and cpuid declarations, guard DECLSPEC_UUID definition.
by Rémi Bernon 25 Jun '24

25 Jun '24

IIUC atexit isn't exported by ucrtbase, but still exists (maybe as a builtin) and is resolved to a module-local symbol which can be used to register functions executed on module process detach. It is called implicitly by C++ compilers to register static destructors. -- v2: include: Define __cpuid(ex) as intrinsics when _MSC_VER is defined. include: Don't import atexit when building with ucrtbase. include: Guard rpcndr.h DECLSPEC_UUID definition. https://gitlab.winehq.org/wine/wine/-/merge_requests/5915
