What steps will reproduce the problem?
1. Compile the attached file as usual (propeller-elf-gcc -m<model> tst.c -o
tst.elf
2. Run tst.elf on any board that supports XMMC and SD (e.g. a C3), using
propeller-load -b <board> -r -t tst.elf
3. Do this for models lmm and xmmc. In xmmc mode, run these additional tests:
propeller-load -b <board> -r -t -z tst.elf
propeller-load -b <board> -r -t -l tst.elf
What is the expected output? What do you see instead?
In LMM mode, there should be 7 cogs and 7 locks free. In XMMC mode, there
should be 6 cogs and 7 locks free. However, in both the -z and the -l cases,
there are only 6 locks free.
Additional information:
I believe the misplaced lock is the in the LMM kernel's lock for the C runtime
of the sd_loader.c or sd_cache_loader.c trampoline programs - nothing frees the
lock before handing over control to vm_start.s.
