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)

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

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

debugging of my weird error. details are on piazza, and can be inferred through comments and printfs when running uw-testbin/argtesttest

confirmed, bug with argtesttest is with a2b, not a2a (assuming a2a is actually fixed, of course)

got execv mostly working... arg2 and argc are kinda off with argtestest

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

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...

believe argument passing in runprogram working, have base execv without agrs working. with args is still not great

have a building kernel, can run old tests, but cannot run new ones. execv clearly needs work

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.
