Before coming to Microsoft, I wrote my own EngAlphaBlend() accelerator driver in 2003 or so. I knew a lot about how things worked from disassembly but after coming to MS in 2004 I quickly destroyed a lot of my own assumptions. Mess? no. Complicated? yes.
well I mean it was too much of a mess in my own work, I know a bit about win32k, but trying to deal with all the xxx, yyy,zzz functions and the locks and everything kinda confused me, and so I gave up. :(
