| | | | | | | | | Get the list of Pstates from OPAL, and use special registers to request a Pstate or check the current Pstate. The turbo Pstates are higher than the cpu's nominal speed, but the OCC's firmware should throttle down the cpu if it would overheat. ok kettenis@

* base tree had only two uses of the printf %n format string, in this file.deraadt2020-07-101-2/+2
| | | | | | | | | Appending "%n" to the format string to capture the output-length in bytes (into an uninitialized variable) is exactly the same as using the printf return value. Why did they do this so unnaturally? (normally we don't change gcc import code, but I'm doing a study of %n prevelance) ok millert
* As suggested by deraadt@, rewrite most of the printf(3) manual pageschwarze2020-07-101-453/+586
| | | | | | | | | | | | | | to properly show the (differing) syntaxes of all the conversion specifications, and reduce the amount of forward references from the list of modifiers to the list of specifiers. While here, properly explain %lc and %ls. Also correct RETURN VALUES, which incorrectly talked about counting characters while actually bytes are counted. Using feedback from millert@, deraadt@, tb@, and Martin Vahlensieck. OK deraadt@, millert@, and tb@ on intermediate versions of this diff and no objections from jmc@.

| | | | | | | | and change bits in the page table entries that doesn't seem to happen reliably on the POWER9 CPU I'm looking at. So make our pmap not depend on this and emulate these bits instead. As far as I can determine Linux doesn't rely on the hardware bits either.

* Fix a warning false positive from clang 10.millert2020-07-091-2/+2
| | | | | | | blf_enc() takes a number of 64-bit blocks to encrypt, but using sizeof(uint64_t) in the calculation triggers a warning from clang 10 because the actual data type is uint32_t. Pass BCRYPT_WORDS / 2 for the number of blocks like libc bcrypt(3) does. OK kettenis@
