From 7ab1fffcd2a504024b16e408de329f7a94553ecc Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 9 Feb 2018 07:45:58 -0800 Subject: [PATCH] vulkan: Add EXT_acquire_xlib_display [v5] This extension adds the ability to borrow an X RandR output for temporary use directly by a Vulkan application. For DRM, we use the Linux resource leasing mechanism. v2: Clean up xlib_lease detection * Use separate temporary '_xlib_lease' variable to hold the option value to avoid changin the type of a variable. * Use boolean expressions instead of additional if statements to compute resulting with_xlib_lease value. * Simplify addition of VK_USE_PLATFORM_XLIB_XRANDR_KHR to vulkan_wsi_args Suggested-by: Eric Engestrom Move mode list from wsi_display to wsi_display_connector Fix scope for wsi_display_mode and wsi_display_connector allocs Suggested-by: Jason Ekstrand v3: Adopt Jason Ekstrand's coding conventions Declare variables at first use, eliminate extra whitespace between types and names. Wrap lines to 80 columns. Explicitly forbid multiple DRM leases. Making the code support this looks tricky and will require additional thought. Use xcb_randr_output_t throughout the internals of the implementation. Convert at the public API (wsi_get_randr_output_display). Clean up check for usable active_crtc (possible when only the desired output is connected to the crtc). Suggested-by: Jason Ekstrand v4: Move output resource fetching closer to use in wsi_display_get_output. This simplifies the error returns in earlier parts of the code a bit. Return VK_ERROR_INITIALIZATION_FAILED from wsi_acquire_xlib_display. Jason says this is the right error message. Suggested-by: Jason Ekstrand v5: randr doesn't pass vscan over the wire, so we set vscan to 0 for randr-acquired modes, and test wsi modes for vscan <= 1 when comparing against randr modes.
