There is:
Built-in Function: void * __builtin_assume_aligned (const void *exp,
size_t align, ...)
but I don't know how it is working out in practice. Note both direct
map arg and the address should be aligned.
However, an argument for dedicated routines is that on CPUs with ERMS
it is faster to
Very interesting, particularly the outrageous assembly for
pmap_{zero,copy}_page().
Is there some way to tell the compiler that the address is already
4096-aligned and avoid the conditionals? Failing that, we could just
adopt the FreeBSD assembly for this.
Does anyone see a problem with introduci
Hello,
I recently took an opportunity to run cross-systems microbenchmarks
