I am studying the pin_user_pages*() family of functions, and I wonder if the outlined workflow requires it. The hugepages do not page out, but they can move WebInstead of having to write to the hugepage to allocate it, we can populate the page right away and it will show up in used pages right away: man mmap ( ...)

Webexplanation of the working of the code and nr_hugepages are configured as required. Finally, the file running the testcase is modified in order to prevent skipping of hugetlb testcases of va_high_addr_switch. This series has been tested on 6.3.0-rc3 kernel, both on arm64 and x86 platforms. Gentle ping, any updates? Web8 May 2024 · Huge page allocations cannot be 100% of a host's memory, there are 4k only uses, and VM hosts should not overcommit guest memory. Approximately, at least a few percent for kernel, caches, administrative programs, and a little free. Most of the remainder could work for huge pages. WebCheck how large your hugepages are: $ grep Hugepagesize /proc/meminfo Normally that should be 2048 kB ≙ 2 MB. Let us say you want to run your virtual machine with 1024 MB. 1024 / 2 = 512. Add a few extra so we can round this up to 550. Now tell your machine how many hugepages you want: # echo 550 > /proc/sys/vm/nr_hugepages jean \\u0026 judes franklin park il
