I need to move on to new projects. :/ (I have some newer Sun and > SGI gear that might need some love someday if I can get the time.) Kyle has more than enough stuff here in Ottawa to keep GCC support going, and to help with further kernel development. A few WD drives would be useful if there are any still around. I'm thinking the rp3440 running hpux 11.31 would be very useful as a comparison base. If that could be arranged, it would be great. A issue came up this week where a 11.31 had a different behavior from 11.11 and 11.23. Currently, I'm seeing improved stability on my rp3440 running SMP. James' last patch to improve vmap flush/invalidate seems to be a a very important change. Comparing it versus the current code in update_mmu_cache, it seems we should limit the flush to when pfn_valid(page_to_pfn(page)) && page_mapping(page) is true. This seems to have further improved stability and I actually got through a full GCC build with make -j4 build. This was something of a build record, but running the testsuite is still painfully slow. I'm continuing to test, but I'm hopeful that we are finally gaining an understanding of the cache issues and the random segvs that result from cache corruption. This will make a broader range of machines usable. Dave -- J.
