Kyle Evans 9c2aaaa997 arm64: lop off another 24MB of KVA for early device mappings
This grows the block enough to fit a 4K 32-bit depth framebuffer; some
firmware would present smaller GOP modes to be able to boot with a
smaller framebuffer on these devices, but the Windows Devkit firmware
is simply not that nice.  Instead, it offers exactly one GOP mode that
matches the current resolution of the attached display, so with limited
control over resolution on most of my displays it'd be nice if we could
Just Work(TM) at 4K.

andrew notes that he has some ideas for removing PMAP_MAPDEV_EARLY_SIZE
entirely, so this limitation could end up removed altogether in the
future.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
