Sorry for the late reply. I was confused by weird kernel behaviors when memory shortage. But, I think that I slowly came to understand that :). Yes, modular kernel requires more memory, mainly because KERN_AS is changed from ``library'' to ``obj'': https://nxr.netbsd.org/xref/src/sys/lib/libkern/Makefile.inc#8 This pulls in all libkern routines to kernel. However, I think that modularization is the only way to prolong sun2 port as far as I can tell. We need to reduce kernel text as much as possible. This is because (1) Our bootloader mapps only 2MB for kernel image. (2) Even though bootloader can load kernel, it hangs here and there, if kernel size is near 2MB. For (1), our GENERIC is very close to this limit, even though almost all additional features are stripped off. I managed to map more 128KB memory, (maybe) not used by firmware, at least on TME: http://www.netbsd.org/~rin/sun2_bootloader_20200315.patch But I don't know whether it works or not on real hardwares. (2) is more serious. When kernel hangs, it is trapped in pagedaemon. I built a kernel with DIAGNOSTIC and LOCKDEBUG, but no failures are detected. Now, I imagine its scenario as follows: Our kernel allocates many memory on demand. Hangs may be the normal operation (not a bug) when memory is allocated with KM_SLEEP or M_WAITOK, but pagedaemon cannot free memory. Swap is not ready in early boot stage, or all memory is wired, or thrashing takes place like ping-pong; suppose two memory segments are required at the same time. pagedaemon swaps out segment 1 to swap in segment 2, and immediately after, it frees segment 2 to pull in segment 1. Then, ``deadlock'' is effectively formed, which is cannot detected by neither DIAGNOSTIC nor LOCKDEBUG. Hangs due to (2) are remarkably mitigated by modularization. More features can be loaded by modload(8), even if kernel stops working when that are statically linked into kernel. This is because kernel text is wired, whereas modules are pageable. 8MB? luxury? :) i've been testing in 4MB tme :) Sorry, s/8MB/7MB/ in the commit log. Framebuffer and etc. reside at PA 0x70 and above. I think that we can no longer support 4MB system because of (2); hangs due to (2) are much more serious for 4MB system than it is in 7MB system. Modern kernel allocates too much things on demand rather than statically allocating them in data segment... GENERIC became not working again due to (2) (even for 7MB). Can I go further, i.e., strip more features that can be provided by modules, or do you have any other ideas? P.S. In many cases of hangs due to (2), I can break into DDB from console. However, in some cases, especially due to "ifconfig lo0 127.0.0.1" in /etc/rc, it does not even accept input from console. I suspect that someone in our network code allocates memory with KM_SLEEP or M_WAITOK in the interrupt context, or with spl raised... Thanks, rin
