# UVM kernel module makefile

|
|
# The following UVM_BUILD_TYPEs are supported: debug, release, and develop.
|
|
# The first two are nearly self-explanatory, but "develop" deserves a little
|
|
# more explanation (below).
|
|
#
|
|
# Description of the UVM build types (UVM_BUILD_TYPE):
|
|
#
|
|
# debug builds: these get debug symbols, no optimization (in order to allow
|
|
# easier stepping through of functions), and debug printing.
|
|
#
|
|
# develop builds: these are "printing" builds, normally without debug symbols.
|
|
# These builds must run at close to normal speeds, so they are optimized, and
|
|
# do not have any debug symbols. However, they do have debug printing output.
|
|
# This allows a convenient way for QA (or anyone) to get a slightly deeper look
|
|
# at what the driver is doing, without the hassle of setting up kernel
|
|
# debugging.
|
|
#
|
|
# release builds: these are just the usual speed-optimized, no-debug,
|
|
# no-printing builds that you would expect most users to run.
