It appears that MSI does not work on either G5 PPC nor on a E5500-based
platform, where other hardware is reported to work fine with MSI.
Both tests were conducted with NV4x hardware, so perhaps other (or even
this) hardware can be made to work. It's still possible to force-enable
with config=NvMSI=1 on load.

drm_crtc_init exposes the XRGB8888 and ARGB8888 formats. In actuality,
ARGB8888's 32-bit depth messes up some formulas that weren't meant for
it, and the alpha is fairly meaningless for the primary plane.
The modesetting logic appears to be fully prepared for RGB565 as well as
XRGB1555 however, as tested with modetest.

We were previously setting the pitch based on a perfectly packed buffer.
This does not necessarily happen. Either modetest started generating
such buffers recently, or earlier testing only happened with well-picked
overlay sizes.
While we're at it, beef up and refactor the error state detection.

Pre-nv50 YUV overlays have stringent requirements for working with the

should instead prevent the framebuffers from being created in the first
place.

Forked from GP107 implementation. Secboot/gr left out as we don't have
signed blobs from NVIDIA in linux-firmware.
(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
so not able to 100% confirm that no other changes from GP107
are needed. Quick testing shows it seems to work well enough
for display. Due to NVIDIA dragging their heels on getting
signed firmware to us, this is the best we can do for now.

The most recent merge commit in airlied/drm-next has problems with
confusing old_crtc_state and new_crtc_state. Use the
for_each_oldnew_crtc_in_state macros to clean up the confusion,
and explicitly look at the correct state instead of looking at
asyh->state.
With these fixes it becomes more obvious what the code is trying to do,
which will hopefully prevent future confusion.

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.
Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:
- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.
After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.

Enable stereoscopic output for HDMI and DisplayPort connectors on
NV50+ (G80+) hardware. We do not enable stereoscopy on older
hardware in case there is some older board that still has HDMI
output but for which we have no logic for setting the Vendor
InfoFrame.
With this, I get an obvious 3D output when using the "testdisplay"

to a 3D-capable HDMI display, for all available 3D modes (be they

drm_mode_set_crtcinfo() does compensation for interlace and
doublescan timing effects already, so do it first and use the
compensated figures instead of the constant "vscan / ilace" terms
that we had before.
And then it turns out that the hardware model for how the timing
parameters are configured is basically the standard model, but
starting one clock before the sync pulse rather than at the start
of the display area, which lets us drastically simplify the
overall timing calculations (verifying the changes by algebraic
operations is left as an exercise for the reader).
Finally, there were a couple of issues with the computation of
m->v.blankus that are addressed here. Interlaced modes would
generate a negative intermediate result. Double scan modes would
generate an overestimate rather than an underestimate. And when
enabling frame-packing modes, a rather extreme overestimate would
be generated. Fixed, by using the timings as adjusted for the
CRTC to find the length of the vertical blanking period instead of
mixing adjusted and pre-adjustment timing parameters.

Reusing the list_head for both is a bad idea. Callback execution is done
with the lock dropped so that alarms can be rescheduled from the callback,
which means that with some unfortunate timing, lists can get corrupted.

that uses it can only be called from a single context.

Backmerge tag 'v4.12-rc3' into drm-next
Linux 4.12-rc3
Daniel has requested this for some drm-intel-next work.
Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.
Changes since v3:
- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment
Changes since v2:
- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:
- Moved defines from drm.h to drm_mode.h
- Changed define prefix from DRM_ to DRM_MODE_PROP_
- Updated uses of the defines to the new prefix
- Removed include from drm_rect.c
- Stopped using the BIT() macro

Commit cae9ff036e effectively disabled the drm poll_helper by checking
the wrong flag to see if the driver should enable the poll or not:
mode_config.poll_enabled is only set to true by poll_init and it is not
indicating if the poll is enabled or not.
nouveau_display_create() will initialize the poll and going to disable it
right away. After poll_init() the mode_config.poll_enabled will be true,
but the poll itself is disabled.
To avoid the race caused by calling the poll_enable() from different paths,
this patch will enable the poll from one place, in the
nouveau_display_hpd_work().
In case the pm_runtime is disabled we will enable the poll in
nouveau_drm_load() once.

The idea here was to avoid having to "manually" program the HW if there's

At least therm/fantog "attempts" to work around this issue, which could

If we restrict this helper to only kms drivers (which is the case) we
can look up the correct mode easily ourselves. But it's a bit tricky:
- All legacy drivers look at crtc->hwmode. But that is updated already
at the beginning of the modeset helper, which means when we disable
a pipe. Hence the final timestamps might be a bit off. But since
this is an existing bug I'm not going to change it, but just try to
be bug-for-bug compatible with the current code. This only applies
to radeon&amdgpu.
- i915 tries to get it perfect by updating crtc->hwmode when the pipe
is off (i.e. vblank->enabled = false).
- All other atomic drivers look at crtc->state->adjusted_mode. Those
that look at state->requested_mode simply don't adjust their mode,
so it's the same. That has two problems: Accessing crtc->state from
interrupt handling code is unsafe, and it's updated before we shut
down the pipe. For nonblocking modesets it's even worse.
For atomic drivers try to implement what i915 does. To do that we add
a new hwmode field to the vblank structure, and update it from
drm_calc_timestamping_constants(). For atomic drivers that's called
from the right spot by the helper library already, so all fine. But
for safety let's enforce that.
For legacy driver this function is only called at the end (oh the
fun), which is broken, so again let's not bother and just stay
bug-for-bug compatible.
The benefit is that we can use drm_calc_vbltimestamp_from_scanoutpos
directly to implement ->get_vblank_timestamp in every driver, deleting
a lot of code.
v2: Completely new approach, trying to mimick the i915 solution.
v3: Fixup kerneldoc.
v4: Drop the WARN_ON to check that the vblank is off, atomic helpers
currently unconditionally call this. Recomputing the same stuff should
be harmless.
v5: Fix typos and move misplaced hunks to the right patches (Neil).
v6: Undo hunk movement (kbuild).

It's overkill to have a flag parameter which is essentially used just
as a boolean. This takes care of core + adjusting drivers.
Adjusting the scanout position callback is a bit harder, since radeon

There's really no reason for anything more:
- Calling this while the crtc vblank stuff isn't set up is a driver
bug. Those places alrready DRM_ERROR.
- Calling this when the crtc is off is either a driver bug (calling
drm_crtc_handle_vblank at the wrong time) or a core bug (for
anything else). Again, we DRM_ERROR.
- EINVAL is checked at higher levels already, and if we'd use struct
drm_crtc * instead of (dev, pipe) it would be real obvious that
those are again core bugs.
The only valid failure mode is crap hardware that couldn't sample a
useful timestamp, to ask the core to just grab a not-so-accurate
timestamp. Bool is perfectly fine for that.
v2: Also fix up the one caller, I lost that in the shuffling (Jani).
v3: Fixup commit message (Neil).

There are many code paths opencoding kvmalloc. Let's use the helper
instead. The main difference to kvmalloc is that those users are
usually not considering all the aspects of the memory allocator. E.g.
allocation requests <= 32kB (with 4kB pages) are basically never failing
and invoke OOM killer to satisfy the allocation. This sounds too
disruptive for something that has a reasonable fallback - the vmalloc.
On the other hand those requests might fallback to vmalloc even when the
memory allocator would succeed after several more reclaim/compaction
attempts previously. There is no guarantee something like that happens
though.
This patch converts many of those places to kv[mz]alloc* helpers because
they are more conservative.

So far we only allowed for 1 retry and just failed the query
- and thereby high precision vblank timestamping - if we did
not get a reasonable result, as such a failure wasn't considered
all too horrible. There are a few NVidia gpu models out there which
may need a bit more than 1 retry to get a successful query result
under some conditions.
Since Linux 4.4 the update code for vblank counter and timestamp
in drm_update_vblank_count() changed so that the implementation
assumes that high precision vblank timestamping of a kms driver
either consistently succeeds or consistently fails for a given
video mode and encoder/connector combo. Iow. switching from success
to fail or vice versa on a modeset or connector change is ok, but
spurious temporary failure for a given setup can confuse the core
code and potentially cause bad miscounting of vblanks and confusion
or hangs in userspace clients which rely on vblank stuff, e.g.,
desktop compositors.
Therefore change the max retry count to a larger number - more than
any gpu so far is known to need to succeed, but still low enough
so that these queries which do also happen in vblank interrupt are
still fast enough to be not disastrously long if something would
go badly wrong with them.
As such sporadic retries only happen seldom even on affected gpu's,
this could mean a vblank irq could take a few dozen microseconds
longer every few hours of uptime -- better than a desktop compositor
randomly hanging every couple of hours or days of uptime in a hard
to reproduce manner.

Atomic helpers really want this instead of the hacked-up legacy
backoff trick, which unfortunately prevents drivers from using their
own private drm_modeset_locks.
Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which
don't yet use the new atomic color mgmt/gamma table stuff. Would be
nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

since gen6), but with atomic and all the ww_mutex stuff it's indeed
hopeless.
Remove ->mode_set_base_atomic from the 2 atomic drivers (i915 and
nouveau) that still had one (both had dummy implementations already
anyway), and shunt atomic drivers in the helpers debug_enter/leave
functions.
I'll leave the code in for radeon and amdgpu, but I think as soon as
amdgpu is atomic we should think about just ripping it out. Only
having it around for radeon and pre-nv50 is rather pointless. This
would also allow us to nuke all that code from fbdev.
Funny part is that _all_ kms drivers set this hook, despite that no
one else provides the required ->mode_set_base_atomic implementation.
The reason I'm jumping on this is that I want to wire up a full
acquire ctx for the benefit of atomic drivers, everywhere. And the
debug_enter/leave implementations call ->gamma_set. And there's just
no way ever we can create an acquire_ctx in the nmi context of kgdb.

The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP
and PCI varieties, rather than a core PCIE chip with a bridge for
AGP/PCI as necessary. As a result, it appears that the MMU is also
non-functional. For AGP cards, the vast majority of the NV4A lineup,
this worked out since we force AGP cards to use the nv04 mmu. However
for PCI variants, this did not work.
Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for
the suggestion. This should be a no-op for NV4A AGP boards, as they were
using it already.

The trouble here is that it does multiple atomic commits under one
drm_modeset_lock_all, which breaks the behind-the-scenes acquire
context magic that function pulls off. It's much better to have one
overall atomic commit. That we still have multiple atomic commits
prevents us from adding some pretty useful debug checks to the atomic
machinery.
Hence it is really a bad idea to call the legacy
drm_crtc_force_disable_all() function. There's 2 atomic drivers using
this still, nouveau and tinydrm. To fix this, introduce a new
drm_atomic_helper_shutdown() by extracting the code from i915.
While at it improve kernel-doc and catch future offenders by
sprinkling a WARN_ON into the legacy function. We should probably move
those into the legacy modeset helpers, too ...
v2: Make it compile on arm drivers too (Noralf).
v3: Correct kerneldoc to point at _disable_all().

This commit reworks the RAM detection algorithm, using RAM-per-LTC to
determine whether a board has a mixed-memory configuration instead of
using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it
should handle all currently known configurations in the very least.
This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB
isn't fully accessible, as well as only detecting half the VRAM on
GF108 boards.
As a nice side-effect, GP10x memory detection now reuses the majority

Since the HS blobs are provided and signed by NVIDIA, we cannot expect
always-consistent behavior. In this case, on GP10x the unload blob may
return 0x1d even though things have run perfectly well. This behavior
has been confirmed by NVIDIA.
So let the callers of the run_blob() hook receive the blob return's
value (a positive integer) and decide what it means. This allows us to
workaround the 0x1d code instead of issuing an error.

On some secure boot instances (e.g. gp10x) the load and unload blobs do
not run on the same falcon. Support this case by introducing a new
member to the ACR structure and making related functions take the falcon
to use as an argument instead of assuming the boot falcon is to be used.
The rule is that the load blob can be run on either the SEC or PMU
falcons, but the unload blob must be always run on PMU.

On SEC, DMEM is unaccessible by the CPU when the falcon is running in LS
mode. This makes communication with the firmware using DMEM impossible.
For this purpose, a new kind of memory (EMEM) has been added. It works
similarly to DMEM, with the difference that its address space starts at
0x1000000. For this reason, it makes sense to treat it like a special
case of DMEM.

SEC2 is the name given by NVIDIA to the SEC engine post-Fermi (reasons
unknown). Even though it shares the same address range as SEC, its usage
is quite different and this justifies a new engine. Add this engine and
make TOP use it all post-TOP devices should use this implementation and
not the older SEC.
Also quickly add the short gp102 implementation which will be used for
falcon booting purposes.

Both registers allow to bind a new context, but NXTCTX will work on all

After setting NXTCTX we trigger a context switch by writing 0x090 and

PMU support has been enabled for r352 ACR, but it must remain optional
if we want to preserve existing user-space that do not include it. Allow
ACR to be instanciated with a list of optional LS falcons, that will not
produce a fatal error if their firmware is not loaded. Also change the
secure boot bootstrap logic to be able to fall back to legacy behavior
if it turns out the boot falcon's LS firmware cannot be loaded.

Adapt secboot's behavior if a PMU firmware is present, in particular
the way LS falcons are reset. Without PMU firmware, secboot needs to be
performed again from scratch so all LS falcons are reset. With PMU
firmware, we can ask the PMU's ACR unit to reset a specific falcon
through a PMU message.
As we must preserve the old behavior to avoid breaking user-space, add a
few conditionals to the way falcons are reset.

A message queue firmware implements a specific protocol allowing the
host to send "commands" to a falcon, and the falcon to reply using
"messages". This patch implements the common part of this protocol and
defines the interface that the host can use.
Due to the way the firmware is developped internally at NVIDIA (where
kernel driver and firmware evolve in lockstep), firmwares taken at
different points in time can have frustratingly subtle differences that
must be taken into account. This code is architectured to make
implementing such differences as easy as possible.
