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 that would not otherwise be able to execute common code. This series adds support to nouveau for two opcodes seen on VBIOSes prior to the locked-down PMU taking over responsibility for executing devinit scripts. Documentation for these two opcodes can be found at: https://github.com/envytools/envytools/pull/189 Rhys Kidd (2): drm/nouveau/bios/init: handle INIT_RESET_BEGUN devinit opcode drm/nouveau/bios/init: handle INIT_RESET_END devinit opcode .../gpu/drm/nouveau/nvkm/subdev/bios/init.c | 26 +++++++++++++++++-- 1 file changed, 24 insertions(+), 2 deletions(-) -- 2.20.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
