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 <<a href="mailto:jason@jlekstrand.net">jason@jlekstrand.net</a>> * Simplify addition of VK_USE_PLATFORM_DISPLAY_KHR to vulkan_wsi_args Suggested-by: Eric Engestrom <<a href="mailto:eric.engestrom@imgtec.com">eric.engestrom@imgtec.com</a>> 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 <<a href="mailto:jason@jlekstrand.net">jason@jlekstrand.net</a>> 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. v5: Set the 'currentStackIndex' member of the VkDisplayPlanePropertiesKHR record to zero, instead of indexing across all displays. This value is the stack depth of the plane within an individual display, and as the current code supports only a single plane per display, should be set to zero for all elements Discovered-by: David Mao <<a href="mailto:David.Mao@amd.com">David.Mao@amd.com</a>> v6: Remove 'platform_display' bits from the build and use the existing 'platform_drm' instead. v7: Ensure VK_ICD_WSI_PLATFORM_MAX is large enough by setting to VK_ICD_WSI_PLATFORM_DISPLAY + 1 v8: Simplify wsi_device_init failure from wsi_display_init_wsi by using the same pattern as the other wsi layers. Adopt Jason Ekstrand's white space and variable declaration suggestions. Declare variables at first use, eliminate extra whitespace between types and names, add list iterator helpers, switch to lower-case list_ macros. Respond to Jason's April 8 review: * Create a function to convert relative to absolute timeouts to catch overflow issues in one place * use VK_NULL_HANDLE to clear prop->currentDisplay * Get rid of available_present_modes array. * return OUT_OF_DATE_KHR when display_queue_next called after display has been released. * Make errors from mode setting fatal in display_queue_next * Remove duplicate pthread_mutex_init call * Add wsi_init_pthread_cond_monotonic helper function to isolate pthread error handling from wsi_display_init_wsi Suggested-by: Jason Ekstrand <<a href="mailto:jason.ekstrand@intel.com">jason.ekstrand@intel.com</a>> Signed-off-by: Keith Packard <<a href="mailto:keithp@keithp.com">keithp@keithp.com</a>> --- src/amd/vulkan/radv_device.c | 8 + src/amd/vulkan/radv_private.h | 1 + src/amd/vulkan/radv_wsi.c | 3 +- src/intel/vulkan/anv_device.c | 4 + src/intel/vulkan/anv_private.h | 1 + src/intel/vulkan/anv_wsi.c | 3 +- src/vulkan/Makefile.am | 7 + src/vulkan/Makefile.sources | 4 + src/vulkan/wsi/meson.build | 8 + src/vulkan/wsi/wsi_common.c | 12 +- src/vulkan/wsi/wsi_common.h | 5 +- src/vulkan/wsi/wsi_common_display.c | 1432 +++++++++++++++++++++++++++ src/vulkan/wsi/wsi_common_display.h | 77 ++ src/vulkan/wsi/wsi_common_private.h | 9 + 14 files changed, 1569 insertions(+), 5 deletions(-) create mode 100644 src/vulkan/wsi/wsi_common_display.c create mode 100644 src/vulkan/wsi/wsi_common_display.h </blockquote></div></div></div>
