Colin Percival 217fce1377 pci: Make PCIe Eject timeout configurable
PCIe mandates a 5 second delay between when the "Attention Button" is
pressed and when the associated device is detached; this is to allow
for the button to be pressed a second time to cancel the ejection.  On
some systems this 5 second delay may not be desireable; so introduce a
hw.pci.pcie_hp_detach_timeout sysctl (which can also be set as a loader
tunable) which specifies the timeout in milliseconds (default 5000).
If set to zero, the device is detached immediately.

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.
