Andriy Gapon 9d6810819c MFV r329713: 8731 ASSERT3U(nui64s, <=, UINT16_MAX) fails for large blocks illumos/illumos-gate@a6c1eb3c08 `a6c1eb3c08` https://www.illumos.org/issues/8731 annotate_ecksum() asserts that nui64s, calculated as nui64s = size / sizeof (uint64_t), is not greater than UINT16_MAX. This restriction is needed because histograms of incorrectly set and cleared bits have 16 bit counters and if the buffer consists of too many 64-bit words, then a counter can potentially overflow producing an incorrect result. When the largest buffer size was 128KB the greatest value of nui64s was 16K, well within the limit. But now we have support for large buffers and for buffer sizes of 512KB and above the restriction is violated.

README.md

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.

The buildkernel and installkernel targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

Note: If you want to build and install the kernel with the buildkernel and installkernel targets, you might need to build world before. More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
