I have have attached a patch for RSB that will enable SMP support for
the sis simulator. This is done by pulling in a second sis patch on top
of the existing one, containing the SMP feature. To enable SMP
operation, start sis with -m <n> where n is between 2 and 4:
$ sparc-rtems5-sis -leon3 -m 4
SIS - SPARC instruction simulator 2.9, copyright Jiri Gaisler 1995
Bug-reports to j...@gaisler.se
LEON3 emulation enabled, 4 cpus online, delta 50 clocks
sis>
I have updated the README files in sis to reflect the new features.
Debugging in gdb works as before, but breakpoints are global until I
manage to add RTEMS threads awareness to sis.
A second (simple) patch is attached for leon3-sis.ini in rtems-tools,
just to allow rtems-test to run the SMP tests.
I will now move to gdb-8.2+ and merge RISCV support to sis.
Jiri.
