yes they all show up as 1024K
cat /sys/devices/system/cpu/cpu*/cache/index*/size

If I am reading the AMD docs right, the L1 cache for each core should
be smaller, and in two parts, (data and instruction cache)
Also appears that L2 should be shared, as far as I can tell, it is
not
shared in this case.
Am I looking at this wrong?
No, that's the right interpretation of lstopo's output.
However, the bug probably lies into your kernel's code. Could you
check
/sys/devices/system/cpu/cpu*/cache/index*/size
?
