I've been confused about the status of the various architectures/BSPs
in the RTEMS >=5 era. My questions for each are:
1. Is libbsd (new network stack) supported?
2. Does it build?
3. Does it boot in emulation? (assuming there is an emulator)
4. Has it been tested on metal?
I think I can answer "yes" to the first 3 for i386/pc686 and powerpc/mvme3100.
Another surprising (to me) question which came up recently is whether
the VME bridge driver is usable on targets without libbsd support.
So maybe my question 1. should be which features depend on libbsd?
The current set of BSPs with configuration in EPICS 7.0 series
repository are:
arm
at91rm9200ek
powerpc
beatnik
mcp750
mvme2100
mvme2700
mvme3100
mvme5500
psim
i386
pc386 (we're switching to pc686 w/ RTEMS5)
m68k
gen68360
mvme167
uC5282
* Toolchain builds
It seems like everyone I know who is working with RTEMS5 is using a different
process to build RTEMS. Some people are using RSB in part or in full. Others
build some piece individually with autoconf or waf (I guess). The result has
been repeatability and "works for me" issues. I'd love to have a recommended
recipe to focus everyone on.
