This post will explain “why” I wrote the kernel the way I did.The linker (link.exe) puts machine code of functions in the source text into the .text section in the order it finds them in the source.All PE headers never add up to a total size that exceeds 4K. So when file alignment is 4K (== memory alignment), the .text Kaushiknoreply@blogger.com3tag:blogger.com,1999:blog-12330967.post-1128194213340775162005-10-01T12:16:00.000-07:002012-01-29T04:12:34.432-08:00Writing multiboot PE kernels using Visual C++Update [1/29/2012]: Source code now available here.
Aspiring operating system developers who target x86 often don’t get beyond writing a boot sector (seldom do they even complete it) because of the inordinate amount of time needed to understand the “tricks” required to get the processor into a “sane” mode of operation before the kernel can start executing. That’s why newbie kernel developers areKaushiknoreply@blogger.com13tag:blogger.com,1999:blog-12330967.post-1125844602183074762005-09-04T07:36:00.000-07:002005-09-04T07:44:56.880-07:00Rotor callstack notes...Just in case I loose my handwritten copy…

All threads running managed code are suspended (after
bringing it to a “GC safe” place)
One or more generations are condemned
Liveliness trace is used to distinguish live from dead objects in- Gen
0 alone for ephemeral collection- Gen 0 + 1 for full collection
If ephemeral collection (copying collection)
Live ephemeral objects are promoted into the elder
