[Mesa-dev] [PATCH mesa 01/21] vulkan: Add KHR_display extension using DRM [v4]
Keith Packard
keithp at keithp.com
Thu Mar 8 07:24:59 UTC 2018
This adds support for the KHR_display extension support to the vulkan
WSI layer. Driver support will be added separately.
v2:
* fix double ;; in wsi_common_display.c
* Move mode list from wsi_display to wsi_display_connector
* Fix scope for wsi_display_mode andwsi_display_connector
allocs
* Switch all allocations to vk_zalloc instead of vk_alloc.
* Fix DRM failure in
wsi_display_get_physical_device_display_properties
When DRM fails, or when we don't have a master fd
(presumably due to application errors), just return 0
properties from this function, which is at least a valid
response.
* Use vk_outarray for all property queries
This is a bit less error-prone than open-coding the same
stuff.
* Remove VK_COMPOSITE_ALPHA_INHERIT_BIT_KHR from surface caps
Until we have multi-plane support, we shouldn't pretend to
have any multi-plane semantics, even if undefined.
Suggested-by: Jason Ekstrand <jason at jlekstrand.net>
* Simplify addition of VK_USE_PLATFORM_DISPLAY_KHR to
vulkan_wsi_args
Suggested-by: Eric Engestrom <eric.engestrom at imgtec.com>
v3:
Add separate 'display_fd' and 'render_fd' arguments to
wsi_device_init API. This allows drivers to use different FDs
for the different aspects of the device.
Use largest mode as display size when no preferred mode.
If the display doesn't provide a preferred mode, we'll assume
that the largest supported mode is the "physical size" of the
device and report that.
v4:
Make wsi_image_state enumeration values uppercase.
Follow more common mesa conventions.
Remove 'render_fd' from wsi_device_init API. The
wsi_common_display code doesn't use this fd at all, so stop
passing it in. This avoids any potential confusion over which
fd to use when creating display-relative object handles.
Remove call to wsi_create_prime_image which would never have
been reached as the necessary condition (use_prime_blit) is
never set.
whitespace cleanups in wsi_common_display.c
Suggested-by: Jason Ekstrand <jason at jlekstrand.net>
Add depth/bpp info to available surface formats. Instead of
hard-coding depth 24 bpp 32 in the drmModeAddFB call, use the
requested format to find suitable values.
Destroy kernel buffers and FBs when swapchain is destroyed. We
were leaking both of these kernel objects across swapchain
destruction.
Note that wsi_display_wait_for_event waits for anything to
happen. wsi_display_wait_for_event is simply a yield so that
the caller can then check to see if the desired state change
has occurred.
Record swapchain failures in chain for later return. If some
asynchronous swapchain activity fails, we need to tell the
application eventually. Record the failure in the swapchain
and report it at the next acquire_next_image or queue_present
call.
Fix error returns from wsi_display_setup_connector. If a
malloc failed, then the result should be
VK_ERROR_OUT_OF_HOST_MEMORY. Otherwise, the associated ioctl
failed and we're either VT switched away, or our lease has
been revoked, in which case we should return
VK_ERROR_OUT_OF_DATE_KHR.
Make sure both sides of if/else brace use matches
Note that we assume drmModeSetCrtc is synchronous. Add a
comment explaining why we can idle any previous displayed
image as soon as the mode set returns.
Note that EACCES from drmModePageFlip means VT inactive. When
vt switched away drmModePageFlip returns EACCES. Poll once a
second waiting until we get some other return value back.
Clean up after alloc failure in
wsi_display_surface_create_swapchain. Destroy any created
images, free the swapchain.
Remove physical_device from wsi_display_init_wsi. We never
need this value, so remove it from the API and from the
internal wsi_display structure.
Use drmModeAddFB2 in wsi_display_image_init. This takes a drm
format instead of depth/bpp, which provides more control over
the format of the data.
