drm/nouveau/mmu: ALIGN_DOWN correct variable

2018-03-16T01:55:04Z

Commit 7110c89bb8852ff8b0f88ce05b332b3fe22bd11e ("mmu: swap out round for ALIGN") replaced two calls to round/rounddown with ALIGN/ALIGN_DOWN, but erroneously applied ALIGN_DOWN to a different variable (addr) and left intended variable (tail) not rounded/ALIGNed. As a result screen corruption, X lockups are observable.

drm/nouveau: Make clock gate support conditional

2018-02-16T04:07:58Z

The recently introduced clock gate support breaks on Tegra chips because no thermal support is enabled for those devices. Conditionalize the code on the existence of thermal support to fix this.

drm/nouveau/clk: fix gcc-7 -Wint-in-bool-context warning

2018-02-02T05:24:10Z

gcc thinks that interpreting a multiplication result as a bool is confusing: drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c: In function 'read_pll': drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c:133:8: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] Adding a temporary variable to contain the divisor helps make it clear what is going on and avoids that warning.

drm/nouveau: Introduce NvPmEnableGating option

2018-02-02T05:24:10Z

This adds the NvPmEnableGating config option to nouveau, which can be used to enable or disable clockgating for supported chipsets. Enabling can be done by passing config=NvPmEnableGating=1 To nouveau. If your chipset supports it, you'll see a message in your kernel log indicating that clockgating is enabled. Since clockgating has only had limited testing thus far, we leave this option disabled by default for now. Signed-off-by: Lyude Paul Reviewed-by: Martin Peres Signed-off-by: Ben Skeggs
