src/sys/dev/qlnx, branch releng/14.3 FreeBSD source tree log2: move log2 functions from linuxkpi to libkern 2025-02-10T10:29:23+00:00 Doug Moore dougm@FreeBSD.org 2024-06-24T07:00:31+00:00 6f309b9d5654b0ddada8d66c23ce028ba009dbcd Linux has a header file that defines an ilog2 function and some simple functions/macros that use it: roundup_pow_of_two, is_power_of_2, rounddown_pow_of_two, and order_base_2. This change moves three of those simple functions (all but is_power_of_2) from linuxkpi to libkern. It also deletes a few implementations of these functions that have previously been copied into code for various device drivers, so that they can use the libkern version. The is_power_of_2 macro was not moved because powerof2 in param.h provides almost the same service already (except that they disagree about whether 0 is a power of two). Since the linux definitions of these functions were copied into FreeBSD 11 years ago, linux has improved them, and this change provides those improvements. In particular, a giant table of log values for evaluating ilog2 for constant values is no longer necessary.
