First I was reimplementing vm_fault_page as coroutine that returns before executing of mo_data_{unlock,request} calls to vm_fault. vm_fault had to analyse state of vm_fault_page for every page in loop and make a decision regarding further behavior (call mo_data_*, go to next page, etc.). But than I've got that this way is much worse, than doing everything in vm_fault_page (like in OSF mach), so I made a back-off and started working on clustered paging from the beginning (at least now I see clearer how things should be). + 8.06.12 Applied Neal's patch that reworks libpager, changed libdiskfs, tmpfs and ext2fs according to new interface. ext2fs isn't finished yet and should be reworked, but looks like I brought some bug to existing implementation and i want first to fix it and than finish rest of ext2fs. Also I pushed some code changes to hurd git repository into my branch mplaneta/gsoc12/working. Now I start working on gnumach implementation of clustered page reading. After this I'm going to implement madvise, than finish ext2fs and start porting of other translators. |
