  tarfeef101 c6987a2215 trying to add vm into the memory init so we never do physical allocation. not working rn though, can't run more than a couple tests sequentially without a tlb miss (Accessing NULL) 6 jaren geleden
  tarfeef101 a4fb607edb there were a few cases of getppages getting called directly, which caused issues after vm_init is true, as that sets first and last to 0 in ram.c, which is used by stealmem. so those would fail after init. hence the issue. i simply changed those to use alloc_kpages, so now there should be no exceptions. ran one set of tests, but those pass now 6 jaren geleden
  tarfeef101 ee5567e1fd got memory management working (no paging). tested. need to do paging, then try cool shit like VM in ram.c for never using physical allocation. i'm probably forgetting something, but that's all i can remember rn 6 jaren geleden
  tarfeef101 e22dd1c049 tlb now randomly kickes entries, code segments are read only 6 jaren geleden

  tarfeef101 2c7d850820 debugging of my weird error. details are on piazza, and can be inferred through comments and printfs when running uw-testbin/argtesttest 6 jaren geleden
  tarfeef101 74156bfff5 confirmed, bug with argtesttest is with a2b, not a2a (assuming a2a is actually fixed, of course) 6 jaren geleden
  tarfeef101 55542e5358 fixed a2a crap 6 jaren geleden
  tarfeef101 4a78e046da fuck piazza 6 jaren geleden
  tarfeef101 11fc2beeac got execv mostly working... arg2 and argc are kinda off with argtestest 6 jaren geleden
  tarfeef101 8b37d7e1e7 tested uw-testbin/argtest with argument passing (no execv), and it works flawlessly. so issue must be with execv specific code as discussed before, but now we have also validated the functionality of the argument copying 6 jaren geleden
  tarfeef101 03416ba12a seems that arg passing may be working after all, but the bad memory reference i get on hogparty is simply due to the execv base functionality not working. hogparty isn't supposed to use argv. perhaps i am not setting up the userspace pointers properly... 6 jaren geleden
  tarfeef101 b9192e35bf believe argument passing in runprogram working, have base execv without agrs working. with args is still not great 6 jaren geleden
  tarfeef101 4c3717c727 have a building kernel, can run old tests, but cannot run new ones. execv clearly needs work 6 jaren geleden
  tarfeef101 8f2d17547d started execv, not sure how caret.proj will do stuff, guess i'll find out when i repoen it. 6 jaren geleden

  tarfeef101 41d0d447bd added a script for non-complete building. also, fixed sys exit. issue was not deleting children that are zombies when parents die. i do that now 6 jaren geleden
  tarfeef101 2c8fab64f4 using the proper palin test, i am passing. think my sleep is the issue, or according to piazza the sleep is exposing issues with address spaces which could be a fork issue. 6 jaren geleden
