Sorry to hijack this thread, but I have a question about i915
interrupts (945GM specifically) that I haven't gotten an answer to
yet, and this thread reminded me of it so I thought I'd ask again:
I hacked the kernel drm stuff on my laptop with 945GM graphics to do
pci_enable_msi() on the graphics device, and I don't see any
interrupts occur.
So can someone with access to details of the 945GM tell me if MSI
interrupts should work, and if so if there's some internal registers
that need to be poked to enable it (beyond what pci_enable_msi()
does).
It's not super-urgent-- I just like using shiny things like MSI, and I
already have ahci, iwl3945 and e1000 working with MSI on my laptop, so
the graphics are the only thing left with an MSI capability that's not
working.
Thanks!
Roland
