* [PATCH] x86_64 irq: Scream but don't die if we receive an unexpected irqEric W. Biederman2006-10-09
| | | | | | | | | | | | | | | | | | | | | | | Due to code bugs or misbehaving hardware it is possible that we can receive an interrupt that we have not mapped into a linux irq. Calling BUG when that happens is very rude, and if the problem is mild enough prevents anything else from getting done. So instead of calling BUG just scream loudly about the problem and continue running. We don't have enough knowledge to know which interrupt triggered this behavior so we don't acknowledge it. This will likely prevent a recurrence of the problem by jamming up the works with an unacknowledged interrupt. If the interrupt was something important it is quite possible that nothing productive will happen past this point. But it is now at least possible to keep working if the kernel can survive without the interrupt we dropped on the floor. Solutions like irqpoll should generally make dropped irqs non-fatal.

Proposed fix: - make "writer holds lock" distinguishable from "reader tries to grab lock" - have __raw_read_trylock() try to acquire the mutex (in LSB of lock), terminating spin if we see that there's writer holding it.

* | | | [PATCH] x86_64 irq: Allocate a vector across all cpus for genapic_flat.Eric W. Biederman2006-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem we can't take advantage of lowest priority delivery mode if the vectors are allocated for only one cpu at a time. Nor can we work around hardware that assumes lowest priority delivery mode is always used with several cpus. So this patch introduces the concept of a vector_allocation_domain. A set of cpus that will receive an irq on the same vector. Currently the code for implementing this is placed in the genapic structure so we can vary this depending on how we are using the io_apics. This allows us to restore the previous behaviour of genapic_flat without removing the benefits of having separate vector allocation for large machines. This should also fix the problem report where a hyperthreaded cpu was receving the irq on the wrong hyperthread when in logical delivery mode because the previous behaviour is restored. This patch properly records our allocation of the first 16 irqs to the first 16 available vectors on all cpus. This should be fine but it may run into problems with multiple interrupts at the same interrupt level. Except for some badly maintained comments in the code and the behaviour of the interrupt allocator I have no real understanding of that problem. Signed-off-by: Eric W.
