It is not advisable to perform devinit if it has already been done. VBIOS will very likely have invoked devinit if the GPU is the primary graphics device, but there is no accurate way to detect this fact yet. This patch adds such a method for gf100 and later chips, by means of the NV_PTOP_SCRATCH1_DEVINIT_COMPLETED bit. This bit is set...

In case of successful suspend, devinit will have to be run and this is the behavior currently hardcoded. However, as FD bug 94725 suggests, there might be cases where runtime suspend leaves the GPU powered, and in such cases devinit should not be run on resume. On GF100+ we have a reliable way to know whether we need to run devinit. Us...

Hello Ben Skeggs, The patch 88524bc06926: "drm/nouveau/devinit: move simple pll setting routines to devinit" from Mar 5, 2013, leads to the following static checker warning: drivers/gpu/drm/nouveau/nvkm/subdev/devinit/nv50.c:53 nv50_devinit_pll_set() info: return a literal instead of 'ret' drivers/gpu/drm/nouveau/nvkm/subdev/devinit/nv50.c...

Turns out some VBIOSes don't actually set the bit in question in 2240c. Use the nv50-style detection to try avoiding running the vbios twice.

NVIDIA GPUs include a common scripting language (devinit) that can be interpreted by a number of "engines", e.g. within a kernel-mode software driver, the VGA BIOS or an on-board small microcontroller which provides certain security assertions (the 'PMU'). This system allows a GPU programming sequence to be shared by multiple entities...
