New Revision: 25501
URL: http://svn.reactos.org/svn/reactos?rev=25501&view=rev
Log:
[10 bug fixes]:
- Simplify KiSelectReadyThread.
- Use ASSERT_IRQL_EQUAL instead of ASSERT_IRQL, because ASSERT_IRQL is braindead and
doesn't actually do what the name proposes. This caused us to miss many critical bugs.
- Don't lower IRQL to PASSIVE_LEVEL after KeInsertQueueApc. This caused a call to
KiExitDispatcher at PASSIVE, which is completely fucked. Also do the same fix in
KeFreezeAllThreads and KeThawAllThreads.
- Implement code in KiDispatchInterrupt to switch to a new thread, but don't enable
for now.
- Fix the KiMask32Array. One of the values was totally off and screwed up
priority/affinity masks.
- Exit the dispatcher in KiAdjustQuantumThread. This wasn't done, thus causing a weird
system state.
- Fix a bug in KiSetPriorityThread which wasn't properly checking the
ProcessReadyQueue member and thus not applying priority changes.
- Fixup lock release and dispatcher exit in wait functions in the NoWait case. It was
inverted and messed up, leading to system inconsistency.
