This makes flashrom sleep more eagerly rather than busy-waiting, observing that most delays in flashrom are either less than 100 microseconds (barely enough time to get any work done, even on a fast machine) or much more than 1 millisecond (very wasteful to busy-loop). Since we believe most systems offer good timer resolution that should provide sleep latency on the order of 100 microseconds, this is a reasonable default. For DOS, the default is set to 50ms because the best available timing source on DOS only ticks at about 20 Hz.

# This file is for cross compiling flashrom for DOS with DJGPP.
|
|
#
|
|
# Make sure the program names match your toolchain
|
|
#
|
|
# Make sure pkg-config can find your self compiles libpci
|
|
# or add the path of your libpci.pc as 'pkg_config_libdir'
|
|
# under [properies] below.
|
|
#
|
|
# If cross-compiling, you may need to set sys_root in the [properties]
|
|
# section because meson otherwise assumes the same sysroot as the
|
|
# system on which you're building and will get the wrong include files
|
|
# (from /usr/include/x86_64 for example) among other possible issues.
