Retest :-)
p.s. part of the nouveau msi problems (from observation, might be not
100% accurate, I am lazy about testing kernels since I'm doing
development on 1 machine):
- It establishes an interrupt twice:
once in drm_pci_request_irq with NULL handler, because it doesn't initialize
.irq_handler
(maybe we can make this a KASSERT)
another time in nvkm_pci_init.
- with the #ifdef notyet
msi_enabled is never set to true.
so code like:
/* Ensure MSI interrupts are armed, for the case where there are
* already interrupts pending (for whatever reason) at load time.
*/
if (pci->msi)
pci->func->msi_rearm(pci);
doesn't happen.
I see upstream nouveau also uses its own pci init code. maybe I
can untangle and fix it there then backport for us for more sanity.
