- Update imported files to compile rtems-libbsd for i386 based BSPs
- Mostly commenting out parts which create compile or link errors in
RTEMS, but aren't needed
- The files in the i386 directory have been moved to common x86 directories by FreeBSD:
- freebsd/sys/x86/x86/legacy.c
- freebsd/sys/x86/include/machine/legacyvar.h
- freebsd/sys/x86/include/machine/specialreg.h
- Add header files in rtemsbsd directory to direct compiler to new files
- cpusets and SMP are currently not supported in libbsd for RTEMS
- Disable the ifc_cpus context variable and replace its usage,
essentially hard-coding for cpu 0
- callout_reset_on takes a cpu which is ignored by the subsequent call
to callout_reset_sbt_on in RTEMS.
- The macro is redefined to discard the cpu argument directly which
enables uses of it with cpu-dependent variables (disabled in
RETMS) without further changes, e.g. in iflib.c.
- Update FreeBSD files in libbsd.py to required by i386 based BSPs
- Some machine specific header files have moved to different directories
in FreeBSD
- Add missing files e1000 network driver (iflib*)
- path-mappings allow to fix autogenerated include paths for some corner
cases of target platforms without the need to change the build system
- Currently used for i386 based bsps
This is not a nice solution but it should work on all chips. As soon as
FreeBSD has a nice solution via the USB PHY driver, this should be
replaced.
Update #3869.
The rtems_bsd_mmcsd_attach_worker acquired the bus without releasing it.
If a MMC device has multiple hardware partitions (like eMMC which
typically has at least one boot partition) the
rtems_bsd_mmcsd_attach_worker would try to acquire the bus multiple
times. This doesn't work.
Doing it right would mean to acquire and release the bus for each
access which would have an performance impact. Beneath that it would
mean that partition switching has to be supported by the RTEMS code too.
There is currently no known use case where the access would be
necessary. Therefore this patch prefers the performance and just avoids
all further hardware partitions.
