[Nouveau] [PATCH 0/6] drm/nouveau: Enable HDMI Stereoscopy
This is an initial implementation of HDMI 3D mode support for the
nouveau kernel driver. It works on all of the hardware that I have
available to test at the moment, but I am unsure as to the overall
approach taken for setting HDMI InfoFrames, there's no support for g84
or gf119 disps, and the criteria for enabling stereo support for an
output seems a bit iffy.
The first four patches arrange to set the HDMI InfoFrames for gt215
and gk104 disps, and provide the parsing side of support for g84 and
gf119 disps.
The fifth patch removes code that sets up the "mandatory" 3D modes.
The requirement is that a display that supports 3D support at least
one of these modes, not that it must support all of them.
The sixth patch enables stereo support on all TMDS outputs, and adds a
term (copied from the i915 driver) to adjust the clock required for
frame-packed stereo modes. The criteria used here for enabling stereo
on an output seems wrong to me, but it's the least wrong thing that
I've been able to come up with so far.
Even just taking the InfoFrame patches and leaving the stereoscopy
patches until the rest of the InfoFrame support is worked out would
probably be a win.

[Nouveau] [PATCH 1/6] drm/nouveau: Extend NVKM HDMI power control method to set InfoFrames
The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode. These days, it
uses a fixed set of InfoFrames. Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.
At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).

[Nouveau] [PATCH 2/6] drm/nouveau: Pass mode-dependent AVI and Vendor HDMI InfoFrames to NVKM
Now that we have mechanism by which to pass mode-dependent HDMI
InfoFrames to the low-level hardware driver, it is incumbent upon
us to do so.
Experimentation on a gt215 device suggests that the Audio InfoFrame
is not required here, possibly being provided by the HDA device
when necessary (because where else would it come from?).

[Nouveau] [PATCH 3/6] drm/nouveau: Use supplied HDMI InfoFrames on GT215 hardware
Now that we have the InfoFrame data being provided, for the most
part, program the hardware to use it.
While we're here, and since the functionality will come in handy
for supporting 3D stereoscopy, implement setting the Vendor
("generic") InfoFrame.
Also don't enable any InfoFrame that is not provided, and disable
the Vendor InfoFrame when disabling the output.
This change should have two net effects: The Audio infoframe will
no longer be configured (because it's not being supplied, not
that it appears to be necessary), and the AVI and Vendor
InfoFrames will start being emitted correctly for the selected
video mode... For GT215 hardware only.

[Nouveau] [PATCH 4/6] drm/nouveau: Use supplied HDMI InfoFrames on GK104 hardware
Now that we have the InfoFrame data being provided, for the most
part, program the hardware to use it.
While we're here, and since the functionality will come in handy
for supporting 3D stereoscopy, implement setting the Vendor
("generic"?) InfoFrame.
Also don't enable any InfoFrame that is not provided, and disable
the Vendor InfoFrame when disabling the output.
Ignore the Audio InfoFrame: We don't supply it, and there is no
indication that the hardware supports it through this interface.

[Nouveau] [PATCH 5/6] drm: Delete "mandatory" stereographic modes
HDMI specification 1.4a, table 8-15 is very explicitly a "must
support at least one of" table, not a "must support all of"
table.
It is not hard to find hardware that does not support some of the
so-called "mandatory" modes.
More seriously, this code generates invalid display modes for both
of the 3D-capable panels that I have (a 42-inch LG TV and a Sony
PlayStation 3D Display).
If we want to be persnickety, one option would be to check the
final list of modes against the table and give some message if
none of them are valid, but it's a whole lot easier just to delete
the code in question.

[Nouveau] [PATCH 6/6] drm/nouveau: Enable stereoscopic 3D output over HDMI
This is a bit sketchy in terms of implementation, with some rough
edges, but for the most part IT WORKS.
That is to say, I get an obvious 3D output when using the
"testdisplay" program from intel-gpu-tools with the "-3"
parameter
and outputting to a 3D-capable HDMI display.
Rough edges include: the criteria for when to enable 3D mode
selection, and the inconsistent support for setting InfoFrames on
HDMI outputs.

Looks like there's no helper for computing such a thing in drm_edid. It's a pretty fixed setup on G84... you're supposed to hook the audio from your sound card into an internal S/PDIF connector, so just leaving the default audio infoframe on in there might be enough.> > Signed-off-by: Alastair Bridgewater <alastair.bridgewater at gmail.com> > --- > drivers/gpu/drm/nouveau/nv50_display.c | 49 +++++++++++++++++++++++++++++++++- > 1 file changed, 48 insertions(+), 1 deletion(-) > > diff --git a/drivers/gpu/drm/nouveau/nv50_display.c b/drivers/gpu/drm/nouveau/nv50_display.c > index 2c2c645..d52d0b8 100644 > --- a/drivers/gpu/drm/nouveau/nv50_display.c > +++ b/drivers/gpu/drm/nouveau/nv50_display.c > @@ -23,6 +23,7 @@ > */ > > #include <linux/dma-mapping.h> > +#include <linux/hdmi.h> > > #include <drm/drmP.h> > #include <drm/drm_atomic.h> > @@ -31,6 +32,7 @@ > #include <drm/drm_dp_helper.h> > #include <drm/drm_fb_helper.h> > #include <drm/drm_plane_helper.h> > +#include <drm/drm_edid.h> > > #include <nvif/class.h> > #include <nvif/cl0002.h> > @@ -2772,6 +2774,28 @@ nv50_hdmi_disable(struct drm_encoder *encoder, struct nouveau_crtc *nv_crtc) > nvif_mthd(disp->disp, 0, &args, sizeof(args)); > } > > +static ssize_t > +nv50_hdmi_pack_infoframe(struct nv50_disp_sor_hdmi_pwr_v0_infoframe *frame_out, > + union hdmi_infoframe *frame_in) > +{ > + uint8_t buffer[17]; /* The header plus two "subpacks" */ > + ssize_t len; > + > + len = hdmi_infoframe_pack(frame_in, buffer, sizeof(buffer)); > + > + frame_out->header = buffer[0] | (buffer[1] << 8) | (buffer[2] << 16); > + frame_out->subpack0_low = buffer[3] | (buffer[4] << 8) | > + (buffer[5] << 16) | (buffer[6] << 24); > + frame_out->subpack0_high = buffer[7] | (buffer[8] << 8) | > + (buffer[9] << 16); > + frame_out->subpack1_low = buffer[10] | (buffer[11] << 8) | > + (buffer[12] << 16) | (buffer[13] << 24); > + frame_out->subpack1_high = buffer[14] | (buffer[15] << 8) | > + (buffer[16] << 16); > + > + return len; > +} > + > static void > nv50_hdmi_enable(struct drm_encoder *encoder, struct drm_display_mode *mode) > { > @@ -2781,6 +2805,7 @@ nv50_hdmi_enable(struct drm_encoder *encoder, struct drm_display_mode *mode) > struct { > struct nv50_disp_mthd_v1 base; > struct nv50_disp_sor_hdmi_pwr_v0 pwr; > + struct nv50_disp_sor_hdmi_pwr_v0_infoframe iframe[3]; > } args = { > .base.version = 1, > .base.method = NV50_DISP_MTHD_V1_SOR_HDMI_PWR, > @@ -2792,17 +2817,39 @@ nv50_hdmi_enable(struct drm_encoder *encoder, struct drm_display_mode *mode) > }; > struct nouveau_connector *nv_connector; > u32 max_ac_packet; > + union hdmi_infoframe avi_frame; > + union hdmi_infoframe vendor_frame; > + int ret; > + int size; > + int frame = 0; > > nv_connector = nouveau_encoder_connector_get(nv_encoder); > if (!drm_detect_hdmi_monitor(nv_connector->edid)) > return; > > + /* Audio InfoFrame apparently not required (supplied by HDA device?) */ > + > + ret = drm_hdmi_avi_infoframe_from_display_mode(&avi_frame.avi, mode); > + if (ret >= 0) {if (!ret) or if (ret == 0) is more idiomatic.> + /* We have an AVI InfoFrame, populate it to the display */ > + args.pwr.flags |= NV50_DISP_MTHD_V1_SOR_HDMI_PWR_FLAG_AVI_INFOFRAME; > + nv50_hdmi_pack_infoframe(&args.iframe[frame++], &avi_frame); > + } > + > + ret = drm_hdmi_vendor_infoframe_from_display_mode(&vendor_frame.vendor.hdmi, mode); > + if (ret >= 0) { > + /* We have a Vendor InfoFrame, populate it to the display */ > + args.pwr.flags |= NV50_DISP_MTHD_V1_SOR_HDMI_PWR_FLAG_VENDOR_INFOFRAME; > + nv50_hdmi_pack_infoframe(&args.iframe[frame++], &vendor_frame); > + } > + > max_ac_packet = mode->htotal - mode->hdisplay; > max_ac_packet -= args.pwr.rekey; > max_ac_packet -= 18; /* constant from tegra */ > args.pwr.max_ac_packet = max_ac_packet / 32; > > - nvif_mthd(disp->disp, 0, &args, sizeof(args)); > + size = sizeof(args.base) + sizeof(args.pwr) + frame * sizeof(args.iframe[0]); > + nvif_mthd(disp->disp, 0, &args, size); > nv50_audio_enable(encoder, mode); > } > > -- > 2.10.2 > > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/nouveau

[Nouveau] [PATCH v2 00/10] Enable HDMI Stereoscopy
HDMI 3D mode support, round two. Revisions include no longer dealing
with audio InfoFrames, passing infoframe data to NVKM as bags of bytes
rather than as data pre-packed for the hardware, more-normal return
value checking for drm_hdmi_*_infoframe_from_display_mode() results,
Frame-Packing mode support, more-principled logic for enabling stereo
mode support on a connector, and support for all four nv50+ DISPs.
Additionally, this patch set is being sent to the dri-devel list as
well as the nouveau list. Dropped in this version is the removal of
the "mandatory" 3D mode logic. After discussion, I'm still
convinced
that it's wrong, but now I'm convinced that it's too conservative
rather than my original belief which was that it was too liberal.
Thanks to Ilia Mirkin, Damien Lespiau, and Ben Skeggs for feedback on
the original patch set. If I have neglected to mention anyone, mea
culpa.
The first patch perhaps isn't technically necessary, but simplifies
the later logic for fixing frame-packing mode timing. There may be
some effect from applying this, as drm_mode_set_crtcinfo() does
something with vscan which can affect the given CRTC timing. I'm
not sure what's going on there, if there's any behavioral change or
not, and if there is what to do about it (other than using
drm_mode_set_crtcinfo() twice, once with CRTC_NO_VSCAN and once
without).
The second through eighth patches are all the InfoFrame logic again,
this time with support for all four DISP types. This does not appear
to cause regressions in HDMI audio on GT215, GF119, or GK104. I hope
that it doesn't cause a regression on G84, but haven't yet managed to
set up a test case for G84 and HDMI audio.
The ninth patch is to fix up frame-packing mode timings and geometry.
As the patch comment says, there are clearly-correct parts, and there
are possibly-hacky parts. But it gets frame-packing modes working,
and we can revise from there if necessary.
And the tenth patch enables stereo mode support... on HDMI and DPort
connectors on nv50+ hardware. HDMI connectors because obvious. DPort
connectors because of DPort to HDMI adaptors. eDP connectors because
it shouldn't do any harm, and someone might have been maniac enough to
set up an eDP port to point to something with an HDMI 3D setup. And
nv50+ hardware only because while I'm not aware of any pre-nv50 cards
that have HDMI outputs, there could be a setup out there like the PS3
that uses an external HDMI encoder on pre-nv50 hardware, at which
point none of the mode timing or InfoFrame support is in place for it.

[Nouveau] [PATCH v2 01/10] drm/nouveau: Use drm_mode_set_crtcinfo() to compensate for vscan / ilace
* 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.
* Also prefer using the mode->crtc_* fields generally instead of
the non-crtc_-prefixed versions, largely to avoid potential
confusion as to why some fields are the crtc_ versions and some
are not, but also in case drm_mode_set_crtcinfo() adds some more
mode-specific logic that we might want to use.
* In one case, we use the non-crtc_-prefixed version of a mode
field, because the original form didn't include a "vscan / ilace"
term.

[Nouveau] [PATCH v2 02/10] drm/nouveau: Extend NVKM HDMI power control method to set InfoFrames
The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode. These days, it
uses a fixed set of InfoFrames. Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.
At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).

[Nouveau] [PATCH v2 03/10] drm/nouveau: Pass mode-dependent AVI and Vendor HDMI InfoFrames to NVKM
Now that we have mechanism by which to pass mode-dependent HDMI
InfoFrames to the low-level hardware driver, it is incumbent upon
us to do so.

[Nouveau] [PATCH v2 04/10] drm/nouveau: Add mechanism to convert HDMI InfoFrames to hardware format
HDMI InfoFrames are passed to NVKM as bags of bytes, but the
hardware needs them to be packed into words. Rather than having
four (or more) copies of the packing logic introduce a single copy
now, in a central place.
We currently need these for AVI and Vendor InfoFrames, but we may
also expect to need them for Audio InfoFrames at some point.

[Nouveau] [PATCH v2 07/10] drm/nouveau: Use supplied HDMI InfoFrames on GF119 hardware
Now that we have the InfoFrame data being provided, for the most
part, program the hardware to use it.
While we're here, and since the functionality will come in handy
for supporting 3D stereoscopy, implement setting the Vendor
("generic"?) InfoFrame.
Also don't enable any InfoFrame that is not provided, and disable
the Vendor InfoFrame when disabling the output.

[Nouveau] [PATCH v2 09/10] drm/nouveau: Handle frame-packing mode geometry and timing effects
* Frame-packing modes add an extra vtotal raster lines to each
frame above and beyond what the basic mode description calls for.
Account for this during scaler configuration (possibly a bit of a
hack), during CRTC configuration (clearly not a hack), and when
checking that a mode is vaild for a given connector (cribbed from
the i915 driver).

[Nouveau] [PATCH v2 10/10] drm/nouveau: Enable stereoscopic 3D output over HDMI
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" program from intel-gpu-tools with the "-3" parameter and outputting to a 3D-capable HDMI display, for all available 3D modes (be they TB, SBSH, or FP) on all four G80+ DISPs.

HDMI connectors because obvious. DPort > connectors because of DPort to HDMI adaptors.Do you mean DP++ or actual protocol converters? DP++ is just HDMI with a some electrical tweaks, but IIRC proper DP defines 3D stereo quite differently than HDMI.

[Nouveau] [PATCH v3 00/10] drm/nouveau Enable HDMI Stereoscopy
HDMI 3D mode support, round three. Rebased to drm-next as it was on
Sunday morning. Overall structure is the same as v2.
Substantially rewrote the first patch (nv50_head_atomic_check_mode())
since a recent change to the calculation of m->v.blankus caused a
merge conflict and problems with frame-packed and interlaced 3D modes,
and I found a much saner model for how the timing parameters work
while I was sorting that out. Observable behavior changes from this
patch should be limited to better values for m->v.blankus on
interlaced non-doublescan modes and non-interlaced doublescan modes,
and some sort of effect on any mode with mode->vscan set (I don't know
if this case actually happens, but if it did then I would expect it to
have had some sort of problem in the previous implementation anyway).
Of the entire series, this first patch is more cleanup-and-bugfix than
anything else, and may be a candidate for merging early even if the
rest of the series is deferred until the next merge window.
Typo-busted the ninth patch (frame-packing geometry and timing) and
adjusted for the rename of drm_crtc_get_hv_timing() to
drm_mode_get_hv_timing().
Possibly some minor whitespace changes in one or two patches, plus
reformatted some of the patch comments.
Tested on my gt215 hardware only at this time, since I'm away from the
rest of my test hardware for about another week. That said, all of
the changes are in the generic nv50 code, rather than being specific
to some chipset or family.
Thanks to Roy Spliet for assistance (mostly background information) in
working out what was going on with m->v.blankus.

[Nouveau] [PATCH v3 01/10] drm/nouveau: Clean up nv50_head_atomic_check_mode() and fix blankus calculation
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.

[Nouveau] [PATCH v3 02/10] drm/nouveau: Extend NVKM HDMI power control method to set InfoFrames
The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode. These days, it
uses a fixed set of InfoFrames. Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.
At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).

[Nouveau] [PATCH v3 04/10] drm/nouveau: Add mechanism to convert HDMI InfoFrames to hardware format
HDMI InfoFrames are passed to NVKM as bags of bytes, but the
hardware needs them to be packed into words. Rather than having
four (or more) copies of the packing logic introduce a single copy
now, in a central place.
We currently need these for AVI and Vendor InfoFrames, but we may
also expect to need them for Audio InfoFrames at some point.

[Nouveau] [PATCH v3 05/10] drm/nouveau: Use supplied HDMI InfoFrames on G84 hardware
Now that we have the InfoFrame data being provided, for the most
part, program the hardware to use it.
While we're here, and since the functionality will come in handy
for supporting 3D stereoscopy, implement setting the Vendor
("generic"?) InfoFrame.
Also don't enable any AVI or Vendor InfoFrame that is not provided,
and disable the Vendor InfoFrame when disabling the output.
Ignore the Audio InfoFrame: We don't supply it, and altering HDMI
audio semantics (for better or worse) on this hardware is out of
scope for me at this time.

[Nouveau] [PATCH v3 09/10] drm/nouveau: Handle frame-packing mode geometry and timing effects
Frame-packing modes add an extra vtotal raster lines to each frame
above and beyond what the basic mode description calls for.
Account for this during scaler configuration (possibly a bit of a
hack), during CRTC configuration (clearly not a hack), and when
checking that a mode is valid for a given connector (cribbed from
the i915 driver).

[Nouveau] [PATCH v3 10/10] drm/nouveau: Enable stereoscopic 3D output over HDMI
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" program from intel-gpu-tools with the "-3" parameter and outputting to a 3D-capable HDMI display, for all available 3D modes (be they TB, SBSH, or FP) on all four G80+ DISPs.
