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.

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:

That's right, there's still more power saving to go! Starting with kepler 2, nvidia hardware has an additional level of clockgating known as second level clockgating. The details of this are not exact, but it seems to work by waiting for a collection of dependent hardware blocks to be gated before taking affect. As with the previous series, this results in another noticeable drop in power consumption and is programmed in the same manner. Signed-off-by:

This enables BLCG optimization for kepler1. When using clockgating, nvidia's firmware has a set of registers which are initially programmed by the vbios with various engine delays and other mysterious settings that are safe enough to bring up the GPU. However, the values used by the vbios are more power hungry then they need to be, so the nvidia driver writes it's own more optimized set of BLCG settings before enabling CG_CTRL. This adds support for programming the optimized BLCG values during engine/subdev init, which enables rather significant power savings. This introduces the nvkm_therm_clkgate_init() helper, which we use to program the optimized BLCG settings before enabling clockgating with nvkm_therm_clkgate_enable. As well, this commit shares a lot more code with Fermi since BLCG is mostly the same there as far as we can tell. In the future, it's likely we'll reformat the clkgate_packs for kepler1 so that they share a list of mmio packs with Fermi. Signed-off-by:

This adds support for enabling automatic clockgating on nvidia GPUs for Kepler1. While this is not technically a clockgating level, it does enable clockgating using the clockgating values initially set by the vbios (which should be safe to use). This introduces two therm helpers for controlling basic clockgating: nvkm_therm_clkgate_enable() - enables clockgating through CG_CTRL, done after initializing the GPU fully nvkm_therm_clkgate_fini() - prepares clockgating for suspend or driver unload A lot of this code was originally going to be based off of fermi; however it turns out that while Fermi's the first line of GPUs that introduced this kind of power saving, Fermi requires more fine tuned control of the CG_CTRL registers from the driver while reclocking that we don't entirely understand yet. For the simple parts we will be sharing with Fermi for certain however, we at least add those into a new subdev/therm/gf100.h header. Signed-off-by:

We've still been directly using the legacy crtc gamma_set() hook even after conversion to atomic modesetting. For userspace clients this was fine, however, fbcon will use the atomic property when it's running on an atomic driver, which means we miss its colormap updates - which is particularly bad for 8bpp framebuffers! This commit converts the driver to use the atomic property + the helper function implementing the legacy hook on top of atomic.

For some reason forgotten by history, we've been using a 1025-entry LUT mode, and sparsely filling it with the 256-entry LUT we're handed. Until we land support for the full atomic colour management properties, this commit switches to using the 257-entry mode to fix colour mapping with depth 30 framebuffers. Reported-by:

This is what was done prior to the big refactor in kernel 3.8, and what was done by xf86-video-nv. Experimentally, it seems like there's some sort of issue with the high-res lut to be used there. Tested on G92. This ends up mattering because fbcon/fbdev chooses the C8 fb format for low-vram systems, which can occur with some IGP-based configurations with little "stolen" vram.

Fixes failure to compile with recent envyas as a result of the 'movw' alias being removed for v5. A bit of history: v3 only has a 16-bit sign-extended immediate mov op. In order to set the high bits, there's a separate 'sethi' op. envyas validates that the value passed to mov(imm) is between -0x8000 and 0x7fff. In order to simplify macros that load both the low and high word, a 'movw' alias was added which takes an unsigned 16-bit immediate. However the actual hardware op still sign extends. v5 has a full 32-bit immediate mov op. The v3 16-bit immediate mov op is gone (loads 0 into the dst reg). However due to a bug in envyas, the movw alias still existed, and selected the no-longer-present v3 16-bit immediate mov op. As a result usage of movw on v5 is the same as mov with a 0x0 argument. The proper fix throughout is to only ever use the 'movw' alias in combination with 'sethi'. Anything else should get the sign-extended validation to ensure that the intended value ends up in the destination register. Changes in fuc3 binaries is the result of a different encoding being selected for a mov with an 8-bit value. v2: added commit message written by Ilia, thanks for that! v3: messed up rebasing, now it should apply Signed-off-by:
