for config_time.h) that contains, for example:
/* Sun Nov 17 05:37:51 2002 GMT */
#define CONFIG_TIME 1037511471
#define CONFIG_YEAR 2002
#define CONFIG_MONTH 11
#define CONFIG_DATE 17
#define CONFIG_HOUR 5
#define CONFIG_MINS 37
#define CONFIG_SECS 51
These values represent the current time as of when config was last
run, so that functions (eg, inittodr()) can use these values instead
of being updated once every year or so with the "current" time.
The associated modification to Makefile.kern.inc makes config_time.h
depend on this depend on this and the kernel Makefile, so that
granularity of kernel builds is not reduced.
XXX the dependencies for the kernel .ln files are just plain wrong. We
need some sort of extended make depend hack to do it right. We will
suffer with it for now.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
compile directory is not under /usr/src/sys (i.e. when 'S' is not
'../../../..'). Pointed out by Robert Elz in PR 17384.
Thanks again to Andrew Brown for figuring out how to rip .depend apart.
Makefiles. The main feature added by these targets is that they cover
ONLY the source files used for a given kernel and no other. Thus when
examining MD routines provided by all machines, you will see only
those applicable for your kernel.
ports. This includes cleaning out DBG, cleaning up the `clean'
target, and tweaking the warnings flags (cesfic, amigappc, and the arm
ports are a little less warning resistant).
Oh, and let's `install' the kernel into ${DESTDIR} if someone says
`make install'. We have to think about cross-compilers here.
that empty values for TEXTADDR and DATAADDR (and ENTRYPOINT) will not
screw things up. Add support for SYSTEM_LD_TAIL_EXTRA which some
ports (not yet converted) are using. Add support for GENASSYM_EXTRAS
which has just been added to (some of) the arm ports.
build features (such as ross's DEBUGLIST) can easily be applied to all
ports. This should reduce the complexity of each port's kernel
Makefile considerably. Line counts:
