Hello,
I tried to build the branch 5-freebsd-12 for the pc686 BSP of the
current
RTEMS master.
The compilation stops at:
[ 64/1156] Compiling freebsd/sbin/sysctl/sysctl.c
../../freebsd/sbin/sysctl/sysctl.c:72:10: fatal error:
machine/pc/bios.h:

compilation terminated.

I tried to build the default and minimal buildset with the same results.
The missing bios.h is available in the full freebsd sources.
Do I need to use the freebsd-to-rtems.py script to integrate the missing
header into the freebsd directory or do I need to do something different?
The code worked on the pc at one point.
What is it getting from bios.h?
My first cut at it would be to import that file. Long term, we would probably
be better off if the PC BSP used more infrastructure from FreeBSD. The current
BSP
is marginally supporting non-legacy PCs.
With some local changes I got rtems-libbsd to compile again, but only without
the E1000 driver.
If the driver is included I get linker errors because it depends on iflib_*
functions.
If I understand libbsd.py correctly then iflib.h is included in the build, but
iflib.c is not.
I don't really get how other BSPs get around this dependency. Or don't they use
E1000 at all?
We only use libbsd on system on chips (m68k, arm and powerpc) without PCI.
