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.

a0f79082bd drm/nouveau: Add support for SLCG for Kepler2
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.

1bab09acc9 drm/nouveau: Add support for BLCG on Kepler1
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.

b138eca661 drm/nouveau: Add support for basic clockgating on Kepler1
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.

f4778f08a0 drm/nouveau/kms/nv50: fix handling of gamma since atomic conversion
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.

e75182f68b drm/nouveau/kms/nv50: use "low res" lut for indexed mode
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.

fe9748b7b4 drm/nouveau/pmu/fuc: don't use movw directly anymore
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.

v3: messed up rebasing, now it should apply

Single irq regression fix

  drm/nouveau: Move irq setup/teardown to pci ctor/dtor
2018-01-26 15:27:07 +10:00
Lyude Paul
0fd189a95f drm/nouveau: Move irq setup/teardown to pci ctor/dtor
For a while we've been having issues with seemingly random interrupts
coming from nvidia cards when resuming them. Originally the fix for this
was thought to be just re-arming the MSI interrupt registers right after
re-allocating our IRQs, however it seems a lot of what we do is both
wrong and not even nessecary.

This was made apparent by what appeared to be a regression in the
mainline kernel that started introducing suspend/resume issues for
nouveau:

        a0c9259dc4 (irq/matrix: Spread interrupts on allocation)

After this commit was introduced, we started getting interrupts from the
GPU before we actually re-allocated our own IRQ (see references below)
and assigned the IRQ handler. Investigating this turned out that the
problem was not with the commit, but the fact that nouveau even
free/allocates it's irqs before and after suspend/resume.

For starters: drivers in the linux kernel haven't had to handle
freeing/re-allocating their IRQs during suspend/resume cycles for quite
a while now. Nouveau seems to be one of the few drivers left that still
does this, despite the fact there's no reason we actually need to since
disabling interrupts from the device side should be enough, as the
kernel is already smart enough to know to disable host-side interrupts
for us before going into suspend. Since we were tearing down our IRQs by
hand however, that means there was a short period during resume where
interrupts could be received before we re-allocated our IRQ which would
lead to us getting an unhandled IRQ. Since we never handle said IRQ and
re-arm the interrupt registers, this would cause us to miss all of the
interrupts from the GPU and cause our init process to start timing out
on anything requiring interrupts.

So, since this whole setup/teardown every suspend/resume cycle is
useless anyway, move irq setup/teardown into the pci subdev's ctor/dtor
functions instead so they're only called at driver load and driver
unload. This should fix most of the issues with pending interrupts on
resume, along with getting suspend/resume for nouveau to work again.

As well, this probably means we can also just remove the msi rearm call
inside nvkm_pci_init(). But since our main focus here is to fix
suspend/resume before 4.15, we'll save that for a later patch.

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

No functional changes as the code already uses crtc_state->mode
to populate the clip, which is also what drm_mode_get_hv_timing()
uses.

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

e062a01e6d drm/nouveau/bar/gk20a: Avoid bar teardown during init
Commit bbb163e189 ("drm/nouveau/bar: implement bar1 teardown")
introduced add a teardown helper function for BAR1. During
initialisation of the Nouveau, initially all the teardown helpers are
called once, before calling their init counterparts. For gk20a, after
the BAR1 teardown function is called, the device is hanging during the
initialisation of the FB sub-device. At this point it is unclear why
this is happening and this is still under investigation. However, this
change is preventing Tegra124 devices from booting when Nouveau is
enabled. To allow Tegra124 to boot, remove the teardown helper for
gk20a.

This is based upon a previous patch by Guillaume Tucker but limits
the workaround to only gk20a GPUs.

74a39954a4 drm/nouveau: use alternate memory type for system-memory buffers with kind != 0
Fixes bug on Tegra where we'd strip kind information from system memory
(ie. all) buffers, resulting in misrendering.

Behaviour on dGPU should be unchanged.

f29f18eb95 drm/nouveau: avoid GPU page sizes > PAGE_SIZE for buffer objects in host memory
While the Tegra (GK20A, GM20B, GP10B) MMUs support large pages in host
memory, we're currently lacking IOMMU support for merging system pages
into large enough chunks to be mapped as such by the GPU.

The core VMM code actually supports automatically determining the best
page size to map with, which is intended for these situations, but for
various complicated reasons the DRM is currently forcing the page size
selection on a per-BO basis.

This should fix breakage reported on Tegra GPUs in the meantime, until
one or both of the above issues are resolved properly.

a121027d27 drm/nouveau/pci: do a msi rearm on init
On my GP107 when I load nouveau after unloading it, for some reason the
GPU stopped sending or the CPU stopped receiving interrupts if MSI was
enabled.

Doing a rearm once before getting any interrupts fixes this.

34112bf493 drm/nouveau/fbcon: fix NULL pointer access in nouveau_fbcon_destroy
When the fbcon object is initialized, but nouveau_fbcon_create is not
called, we run into a NULL pointer access within nouveau_fbcon_create when
unloading nouveau.

The call to drm_fb_helper_funcs.fb_probe is deferred until there is a
display for real since 4.14, that's why fbcon->helper.fb is still not set.
