Here's a series of extensions necessary to perform reasonable direct
display operations, either directly through DRM with no window system,
or using RandR and Linux leases.
There's one new extension, MESA_query_timestamp which performs the
same operation as glGetInteger64v(GL_TIMESTAMP, ×tamp) -- it gets
the current GPU tick using an immediate register read so that the
application can correlate GPU and CPU times. I'd love to be able to
have a single call that got both CPU and GPU times so we could put
that in the kernel, but there's no standard timestamp for the various
winsys layers (although most (all?) appear to use MONOTONIC currently,
at least on Linux).
I've refactored this series so that each patch adds a single
extension, and the code for each extension is generally grouped
together. I did not split the code in the new wsi_common_display.c
apart; it's all related to implementing various modes related to
KHR_display, so I didn't see a good place to break it apart that
wouldn't end up with a bunch of extra complexity.

This adds support for the KHR_display extension to the anv and radv
Vulkan drivers. The drivers now attempt to open the master DRM node
when the KHR_display extension is requested so that the common winsys
code can perform the necessary operations.

To: mesa-dev; +Cc: Keith Packard, dri-devel
This extension is required to support EXT_display_control as it offers
a way to query whether the vblank counter is supported.
v2: Thanks to kisak
Fix spelling of VkSurfaceCapabilities2EXT in wsi_common_wayland.c,
it was using ext instead of EXT.
Fix spelling of VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_EXT
v3: Fix wayland WSI, regularize spelling
Misspelled 'surface' in get_capabilities2ext
Remove extra _ from get_capabilities_2ext in a couple of places
v4: Add anv support

This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.
v2: Remove DRM_CRTC_SEQUENCE_FIRST_PIXEL_OUT flag. This has
been removed from the proposed kernel API.
Add NULL parameter to drmCrtcQueueSequence ioctl as we
don't care what sequence the event was actually queued to.
v3: Adapt to pthread clock switch to MONOTONIC
v4: Add support for anv

From: Keith Packard @ 2018-02-10 4:45 UTC (permalink / raw)
To: mesa-dev; +Cc: Keith Packard, dri-devel
This extension adds a single function to query the current GPU
timestamp, just like glGetInteger64v(GL_TIMESTAMP, ×tamp). This
function is needed to complete the implementation of
GOOGLE_display_timing, which needs to be able to coorelate GPU and CPU
timestamps.

From: Keith Packard @ 2018-02-10 4:45 UTC (permalink / raw)
To: mesa-dev; +Cc: Keith Packard, dri-devel
This adds support for the VK_GOOGLE_display timing extension, which
provides two things:
1) Detailed information about when frames are displayed, including
slack time between GPU execution and display frame.
2) Absolute time control over swapchain queue processing. This allows
the application to request frames be displayed at specific
absolute times, using the same timebase as that provided in vblank
events.
Support for this extension has been implemented for the x11 and
display backends; adding support to other backends should be
reasonable straightforward for one familiar with those systems and
should not require any additional device-specific code.

Hi Keith,
A few top level comments:
- using card/primary node and (missing) authentication
Current code opens the primary node when VK_KHR_display is available.
Thus running a platform=drm,x11,wayland build will fail, as the client
is not authenticated with the X/WL server.
- reuse "drm" as a shorthand for the "display"
We've been using drm for egl/gbm, va/drm, etc, one less platform plus
no equivalent in either of egl/va/...
- remove conditional compilation based on library version/features.
Eg. checks like the following should be avoided.
#if DRM_EVENT_CONTEXT_VERSION
- use drmModeAddFB2 (or the withModifiers version even) over drmModeAddFB
Might help with the XXX just above it ;-)
- the spec says we're at VK_KHR_display rev 21, while the code advertises rev1
Extension('VK_KHR_display', 1,
'VK_USE_PLATFORM_DISPLAY_KHR'),
- there are plenty of unnecessary of headers #include(d)
- we could simplify the ifdef spaghetti by making
wsi_*_{init,finish}_wsi empty stubs
Definitely something that can be done, independently of your work.
HTH
Emil

That's actually intentional -- any system which supports 'drm' can
support the display backend as it's based on that. Maybe it should use a
different test? (note that I haven't been using the autotools backend
recently, so it may not be great at this point. At least my current tree
builds?)

Oh, good point -- I'd split out the RANDR and DISPLAY bits but didn't
simplify the meson stuff.

Thanks; I'll reconfigure my environment so that it uses tabs in that
directory, and re-indent the changes.

Good catch; those got left in both anv and radv directories after some
refactoring.

Could do; I could also just strip out the printf debugging, but when
you're doing timing-sensitive stuff at that level, printf debugging is
pretty useful.

Yeah, would probably look cleaner.

Thanks for reviewing the basic formatting and structure though; I
totally missed the tabs/spaces issue.

this is really mostly there to make it easy to test the KHR_display
backend without needing any further code. I added this only recently for
this purpose. I'm not sure how we should be selecting for opening the
primary device; perhaps another extension that adds a block in the pNext
chain to look for?
I don't know if you saw the first version of this series, but I had
specified a new extension which provided the device FD from the
application, letting you pass in whatever you could open (including a
leased FD from X or a primary opened from the application). That seems
like it could use some design ideas so we can make this do what we
want.
One option would be to remove the primary device code from the drivers
once the leasing code is added so that the only way to use KHR_display
is by leasing resources from the window system?
The radv driver goes a bit further and checks with the kernel to see if
rendering will work. For anv, the ioctls necessary for drawing are
permitting on a non-authenticated node. Both drivers work fine for
direct and X as-is, but I'm not very happy with having a random app with
the primary device open as that seems like a mistake waiting to happen.

Yeah, anything that supports drm can support display. I'll review the
build process and try to simplify it further.

Should I just have the build depend on a recent enough version of the library?

It won't help with that -- I just need more information from the
driver. However, that information could come back as a format instead of
depth/bpp, which would mean using drmModeAddFB2 instead of
drmModeAddFB. Thanks for reminding me of this XXX. wsi_create_*_image
gets a VkSwapchainCreateInfoKHR which has a VkFormat inside. Is that
sufficient to compute a fourcc format for AddFB2? I think I could
probably guess depth/bpp from it and be right most of the time?

Thanks. The version of the spec I've got (1.0.49) says it's already at
rev 23!

As is often the case. I can go trim things down.

That would be lovely.

I'm assuming the correlation is done outside the vulkan driver? With a
clock_gettime() maybe?
If that's the case, I'm afraid this will be highly inaccurate.
The kernel might execute other tasks when the ioctl() happens and that
might introduce (in my experience) a few milliseconds of delay.
I think if you want to do something like that, this has to be
implemented in the kernel, making sure you disable interruptions while
doing the correlation.

Yes, I agree. The trouble is that the window system layer works in one
time base while the rendering layer works in the other, so there's no
one driver which has access to both values, at least in Mesa.

That was my thinking originally, until I realized that there wasn't a
single place which knew of the two clocks.
Suggestions are welcome; I just don't know how the rendering driver is
supposed to know what timebase the window system is running in?

It seems a little odd to me to default to opening the master node and then
fall back to the render node if it doesn't work. I suppose that's probably
ok so long as we ensure that vkGetPhysicalDeviceDisplayPropertiesKHR
returns no displays if we're on the render node.
We could always go back to the DRM fd extension idea but I'm not coming up
with something nice and clean in the 60 seconds I've thought about it.

Any particular reason why the list of modes is global and not in the
connector? It seems like it would be a tiny bit more efficient and
convenient to put the list in the connector.

Since we're allocating these in a physical device query, we need to use the
INSTANCE scope. the OBJECT scope is intended for vkCreate functions to
allocated data that will live no longer than the associated vkDestroy
function.

Hooray for obviously false fixed constants!
I know the answer to this will be "EDIDs lie, never trust them!" but can we
get the real value somehow? As someone who has a 13" laptop with a
3200x1800 display, I know that number isn't always right. :-)

I know i915 can do better at least in some cases. Is there a practical way

This error is not allowed for this function. We should just write 0 to
property_count and return VK_SUCCESS. Maybe add some asserts for debug
builds if you really think this shouldn't ever happen.

This could be made a lot easier with vk_outarray:
VK_OUTARRAY_MAKE(conn, properties, property_count);
for (int c = 0; c < mode_res->count_connectors; c++) {
connector = wsi_display_get_connector(wsi_device,
mode_res->connectors[c]);
if (!connector) {
drmModeFreeResources(mode_res);
return VK_ERROR_OUT_OF_HOST_MEMORY;
}
if (connector->connected) {
vk_outarray_append(&conn, prop) {
wsi_display_fill_in_display_properties(wsi_device, connector,
prop);
}
}
}
drmModeFreeResources(mode_res);
return vk_outarray_status(&conn);
It's a bit magic but a lot less typing and you don't have to think about
all the details of whether or not you've gotten the return value right.

It's not entirely clear what the stack index for a disabled plane should
be. I guess 0 is as good as anything.

This isn't correct. The loop below could turn up no displays. Again,

One of these is wrong. Either you have zero displays or you have one
display and it's VK_NULL_HANDLE.

Yeah, I sound like a broken record now. vk_outarray. I think this one is
actually correct, so you could leave it alone if you wanted.

That would be good. I don't know enough about KMS to know where you'd get

I don't think INHERIT is really appropreate here. I don't think it's
practical to set the transparency using KMS without doing it as part of the
modeset. Since it really has to be insde the WSI code, we just want
OPAQUE_BIT for now.

As I said in the last comments about this section, Dave Airlie and I
added this code only recently so that we could test this extension
without also needing the kernel and X leasing changes.
I think we should decide how to enable this functionality "for real",
and I have two easy options:
1) Use my KEITHP_kms_display extension (presumably renamed MESA), which
exposes a way to pass the DRM fd from the application into the
driver. This makes it possible for the application to get the FD
through any mechanism at all (including RandR or the new Wayland
extension) and leave that out of the Vulkan code entirely.
2) Add a new extension which passes a new data structure that directs
the driver to open either the Render or Primary nodes.
When this is done, we can switch from the current code which tries to
open the Primary node whenever the KHR_display extension is requested.

Nope -- once we add the acquire_xlib extension, we get modes through
either X or DRM, depending on whether we're pre-lease or post-lease.

I think you're right. I have some vague memory of a lifetime issue with
connectors, but can't think of what it might be, even after reviewing
the relevant parts of the Vulkan spec. I've gone ahead and changed it;
seems to work fine.

Well, that was easy to fix -- the condition is now gone :-)

Thanks! The whole Vulkan memory model remains a mystery to me.
I've changed allocation of wsi_display_mode and wsi_display_connector to
use SCOPE_INSTANCE. VkIceSurfaceDisplay, wsi_display_fence and
wsi_display_swapchain remain using SCOPE_OBJECT.
I've also changed *all* instances of vk_alloc to use
vk_zalloc. These are all small data structures allocated only during
application startup, so I think the benefit of known memory contents is
worth the cost of memset.

Yes, we could dig the real value out of the EDID, but we'd have to parse
the entire EDID to manage that. I don't want to stick an EDID parser
directly in Mesa, so I'm kinda waiting for someone to create a separate
EDID parsing library that the X server, Mesa and others can share. Until
then, I'd prefer to just lie here.

Thx. I remember seeing this while reviewing patches and forgot all about
it...

I did this intentionally -- most monitors have a preferred resolution,
which is their native pixel size. And, we want to tell applications to
use that size, even if the monitor offers a larger (presumabl scaled)
resolution in their mode list.

Yeah, see response about not boiling the EDID ocean above ;-)

I'm not seeing this exposed through the common DRM mode interfaces
yet. We should probably consider adding this to the kernel and then
adding it here.

I bet it will happen if you VT switch away and then try this function.
I've added this at the end of the function:
bail:
*property_count = 0;
return VK_SUCCESS;

I've replaced all of the array returns with vk_outarray; I'm afraid I
found a bunch of open-coded versions of this and didn't stumble on
vk_outarray until too late. Thanks!

I think the real values will only be useful once we add multi-plane
support to this code. At this point, with only a single plane, I'm not
sure it's interesting to be able to pan it around? So, these values are
'safe', and sufficient to display a single plane covering the full
screen. When we want more, we can go actually hook up multi-plane

With just KHR_display, you can't get here without already having needed
a master FD -- you need a VkSurfaceKHR, and you create one of those
using vkCreateDisplayPlaneSurfaceKHR, which requires a plane and a mode;
a mode comes from vkGetDisplayModePropertiesKHR or
vkCreateDisplayModeKHR, both of which requires a VkDisplayKHR. A
VkDisplayKHR comes from vkGetPhysicalDeviceDisplayPropertiesKHR, which
fails if you don't have a master FD.
Once we have AcquireXlibDisplay, then you will be able to create display
surfaces before you have a master FD as you can create modes using X
resources. And, you can't actually tell if you will be able to get a
master FD until you try...

Yeah, another area which really needs to wait until we figure out what
we want for multi-plane support. If you only have one plane, you don't
exactly have any alpha compositing.

Thanks so much for your review so far; getting rid of the open-coded
property queries is really valuable, along with using vk_zalloc
everywhere.
The "new" patches are exactly the same code changes, just split into
core/anv/radv bits to make Dave Airlie happy. Feel free to either
continue with the old patches or to switch over. I've pushed out a
series of tiny patches which address each of the review comments above
separately if you want to check those over. I'll merge them into the
main patch series at some point.

I think I like option 1. If the client knows the difference between render
and primary for 2, then they are most likely already opening the master
node themselves or at least have access to the FD.
For an application that just wants to draw some stuff on the screen and is
ok with letting Vulkan fully handle KMS for it, the current code may be a
fine solution.
Sorry, I'm just not feeling all that opinionated about this at the moment.

Yes, *if* it has a preferred resolution, we should return that one. If it
doesn't, we should walk the list and return the largest instead of just
defaulting to 1024x768. At least that's what the spec seems to say to me.

Ok, I'll work on cleaning up that extension and renaming it. I have no
idea how to get new words into the Vulkan spec, but it would be good to
have that done too.
I guess the question is whether I should bother to leave the current
try-to-open-primary kludge in place. In good news, under X, both radv
and anv "fail" to use the primary device as another master is already
running, so at least we aren't running with a primary FD open?
> Sorry, I'm just not feeling all that opinionated about this at the moment.

No more than I; either way is fine with me, if you're happy to use
something like the existing code I've got, that's even nicer.

A library would be nice; we have the edid data everywhere, we just don't
have it in a useful form except inside the X server and kernel.

Oh. I totally missed that part. Yeah, that's just wrong. I've just
pushed a patch that finds the largest mode when there isn't a preferred
one. Oddly, I have no devices here which don't specify a preferred mode,
so it will be somewhat difficult to test...
> Yup. Let's just drop INHERIT and only advertise OPAQUE.
Done.
I've updated my drm-lease branch with all of these changes merged into
the existing patches (and so noted), plus the new patch described above
which looks for the largest mode when no preferred mode is specified.
Thanks again for all of your careful review; while we haven't changed
any significant semantics, we have found a bunch of outright bugs in the
code.

Once we're sure that's what we want, create an MR against the spec that
just adds enough to the XML to reserve your extension number. That will
get merged almost immediately. Then make a second one with the actual
extension text and we'll iterate on that either in Khronos gitlab or, if
you prefer, you can send it as a patch to mesa-dev and then make a Khrons
MR once it's baked.

Yeah, in the scary new world of Wayland compositors, having an edid library

properly themselves.

Glad to help. :-) I figure I should learn something about KMS one day and
reviewing this is as good an opportunity as any.

I just wrote up the full extension description for both extensions I
need (the one for passing a KMS fd to the driver, and the second to get
the GPU timestamp for doing GOOGLE_display_timing):

Yeah, I think I've got that all cleaned up now -- the code no longer
shares the same file for rendering and display.

Hi Keith,
If I read the patch correctly, the plane has been interpreted as the same as connector, and the stackIndex is the index of connector of current device.
Is it by intentional?
If the hardware don't have underlay/overlay supported, is it better to always report plane 0 rather than pretend to have multiple plane?
Thanks.
Best Regards,
David

Subject: [PATCH 1/7] vulkan: Add KHR_display extension to anv and radv using DRM
This adds support for the KHR_display extension to the anv and radv
Vulkan drivers. The drivers now attempt to open the master DRM node
when the KHR_display extension is requested so that the common winsys
code can perform the necessary operations.
