12 Più precisamente, il kernel viene compilato con ``gcc`` [it-gcc]_ usando
13 l'opzione ``-std=gnu11`` [it-gcc-c-dialect-options]_: il dialetto GNU
15 Linux supporta anche ``clang`` [it-clang]_, leggete la documentazione
18 Questo dialetto contiene diverse estensioni al linguaggio [it-gnu-extensions]_,

134 - Write 0 to disable it, and 1 to enable it.
135 - Read 0 means it's disabled, 1 it's enabled.
137 If it's enabled, that means that the GPU is free to enter into GFXOFF mode as
138 needed. Disabled means that it will never enter GFXOFF mode.
143 Read it to check current GFXOFF's status of a GPU::
154 getting into 0 when possible. When it's disabled, it's always at 2. Returns
155 ``-EINVAL`` if it's not supported.
