From 2a8f63caf3e4f96132812e02ac6200d6e33ecc44 Mon Sep 17 00:00:00 2001 From: Martin Peres Date: Sun, 4 Nov 2012 01:01:53 +0100 Subject: pbus: add a PBUS subdev that hands IRQs to the right subdevs We are going to use PTHERM's IRQs for thermal monitoring but we need to route them first. On nv31-50, PBUS's IRQ line is shared with GPIOs IRQs. It seems like nv10-31 GPIO interruptions aren't well handled. I kept the original behaviour but it is wrong and may lead to an IRQ storm. Since we enable all PBUS IRQs, we need a way to avoid being stormed if we don't handle them. The solution I used was to mask the IRQs that have not been handled. This will also print one message in the logs to let us know. v2: drop the shared intr handler because of was racy v3: style fixes v4: drop a useless construct in the chipset-dependent INTR v5: add BUS to the disable mask v6 (Ben Skeggs): - general tidy to match the rest of the driver's style - nva3->nvc0, nva3 can be serviced just fine with nv50.c, rnndb even notes that the THERM_ALARM bit got left in the hw until fermi anyway.. so, it's not going to conflict - removed the peephole and user stuff, for the moment.. will handle them later if we find a good reason to actually care.. - limited INTR_EN to just what we can handle for now, mostly to prevent spam of unknown status bits (seen on at least nv4x) Signed-off-by: Ben Skeggs Signed-off-by: Martin Peres --- configure.ac | 1 + 1 file changed, 1 insertion(+) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index b5c59d3a8..0c75e971e 100644 --- a/configure.ac +++ b/configure.ac @@ -70,6 +70,7 @@ AC_OUTPUT( Makefile \ nvkm/subdev/Makefile \ nvkm/subdev/bar/Makefile \ nvkm/subdev/bios/Makefile \ + nvkm/subdev/bus/Makefile \ nvkm/subdev/clock/Makefile \ nvkm/subdev/device/Makefile \ nvkm/subdev/devinit/Makefile \ -- cgit v1.2.1
