Implement VOCTRL_GET_DISPLAY_FPS and VOCTRL_GET_DISPLAY_RES by returning
values obtained from Vulkan.
Currently, display fps and resolution info is not available in the
displayvk context. Display fps is needed for display sync to work
properly. The information is also used as the value of a few properties.
This slightly improves parity with the drm context.
Set UPDATE_VO to GPU API options that are only set on init.
To change multiple options without multiple reinits, use
set vo null; set opengl-foo 1; set opengl-bar 1; set vo gpu
Now that obj_settings_list is used for GPU contexts, detailed
descriptions can be added so that --gpu-context=help can print
the descriptions of the GPU contexts using standard
obj_settings_list help printing.
This change is mostly motivated by missing
VK_KHR_portability_enumeration instance extension when enumerating the
devices. Which causes issues with MoltenVK which does not advertise full
Vulkan conformance.
To avoid duplicating code use pl_vk_inst_create() which correctly query
availability and enables the mentioned extension.
While at it fix the VkInstance leaking in vk_validate_dev().
In many cases, this is purely cosmetic because poll still only accepts
microseconds. There's still a gain here however since
pthread_cond_timedwait can take a realtime ts now.
Additionally, 37d6604d70 changed the value
added to timeout_ms in X11 and Wayland to ensure that it would never be
0 and rounded up. This was both incomplete, several other parts of the
player have this same problem like drm, and not really needed. Instead
the MPCLAMP is just adjusted to have a min of 1.
While the basic Vulkan Display context can theoretically drive the
display without the involvement of any non-Vulkan code, that prevents
us from using VAAPI acceleration. When initialising VAAPI without a
window system, we need to provide it with an opened DRM render fd
corresponding to the device to use.
In the context of using VK_KHR_display, that means we need to identify
which DRM device matches the selected Vulkan device, and then open its
render fd and set the necessary state that VAAPI expects to find.
With that done, the normal VAAPI<->Vulkan interop can kick in and we
get working acceleration
If a plane is not connected to any displays, we won't set an entry in
the mapping of planes to displays. So ensure these unset entries are
null and skip them.
Fixes#8913
This is the Vulkan equivalent of the drm context for OpenGL, with
the big difference that it's implemented purely in terms of Vulkan
calls and doesn't actually require drm or kms.
The basic idea is to identify a display, mode, and plane on a device,
and then create a display backed surface for the swapchain. In theory,
past that point, everything is the same, and this is in fact the case
on Intel hardware. I can get a video playing on a vt.
On nvidia, naturally, things don't work that way. Instead, nvidia only
implemented the extension for scenarios where a VR application is
stealing a display from a running window system, and not for
standalone scenarios. With additional code, I've got this scenario to
work but that's a separate incremental change.
Other people have tested on AMD, and report roughly the same behaviour
as on Intel.
Note, that in this change, the VT will not be correctly restored after
qutting. The only way to restore the VT is to introduce some drm
specific code which I will illustrate in a separate change.
