-Memory in skiboot
------------------
-
-There are regions of memory we statically allocate for firmware as well as
-a HEAP region for boot and runtime allocations.
-
-A design principle of skiboot is to attempt not to allocate memory at runtime,
-or at least keep it to a minimum, and not do so in any critical code path
-for the system to remain running.
-
-At no point during runtime should a skiboot memory allocation failure cause
-the system to stop functioning.
-
-HEAP
-----
-
-Dynamic memory allocations go in a single heap. This is identified as
-Region ibm,firmware-heap and appears as a reserved section in the device tree.
-
-Originally, it was 12582912 bytes in size (declared in mem_map.h).
-Now, it is 13631488 bytes after being bumped as part of the GCOV work.
-
-We increased heap size as on larger systems, we were getting close to using
-all the heap once skiboot became 2MB with GCOV.
-
-Heap usage is printed before running the payload.
-
-For example, as of writing, on a dual socket Tuleta:
-[45215870591,5] SkiBoot skiboot-5.0.1-94-gb759ce2 starting...
-[3680939340,5] CUPD: T side MI Keyword = SV830_027
-[3680942658,5] CUPD: T side ML Keyword = FW830.00
-[15404383291,5] Region ibm,firmware-heap free: 5378072
-
-and on a palmetto:
-[24748502575,5] SkiBoot skiboot-5.0.1-94-gb759ce2 starting...
-[9870429550,5] Region ibm,firmware-heap free: 10814856
-
-Our memory allocator is simple, a use pattern of:
-A = malloc();
-B = malloc();
-free(A);
-
-is likely to generate fragmentation, so it should generally be avoided
-where possible.
