Lynne	ac092c6707	hwcontext_vulkan: guard all uses of new spec defines and fix stray bracket This fixes compilation with less recent Vulkan headers.	3 months ago
Lynne	356d1cc8ff	vulkan: parse instance list and add the DEBUG_UTILS extension Required to let users know whether debugging is active.	3 months ago
Lynne	535e5eb7f3	hwcontext_vulkan: enable VK_KHR_shader_relaxed_extended_instruction	3 months ago
Lynne	bc36fe6f1f	vulkan: use push descriptors where possible Push descriptors are in theory slightly faster, but come with limitations for which we have to check. Either way, they're not difficult to implement, so even though no one should be using peasant-tier descriptors, do it anyway.	3 months ago
Lynne	46c13834b6	hwcontext_vulkan: enable VK_KHR_video_maintenance1 We require it for encoding.	5 months ago
Lynne	2ce0e51503	hwcontext_vulkan: add support for Vulkan encoding	5 months ago
Lynne	55adcb4fc5	hwcontext_vulkan: add support for VK_EXT_shader_object We'd like to use it eventually, and its already covered by the minimum version of the headers we require.	5 months ago
Lynne	a30b7c0158	hwcontext_vulkan: initialize optical flow queues if available Lets us implement FPS conversion.	5 months ago
Lynne	ecdc94b97f	vulkan_av1: port to the new stable API Co-Authored-by: Dave Airlie <airlied@redhat.com>	9 months ago
Andreas Rheinhardt	0a05577d1e	avutil/vulkan_loader: Avoid relocations for strings To do so, concatenate all the names together to one big string name1\0name2\0....lastname\0\0. This avoids the pointer in the FunctionLoadInfo structure and thereby moves vk_load_info into .rodata (and makes it smaller by 888B).

Andreas Rheinhardt	674f20813d	avutil/vulkan_loader: Use smaller types Saves 16B per entry here (four of these 16 bytes are padding); leads to 1776 B of savings in each file that uses ff_vk_load_functions().

Andreas Rheinhardt	e9b4f4461f	avutil/vulkan_loader: Avoid redundant strings and relocations There are three possible names for the functions requested; they only differ in an extension: "", "EXT" or "KHR". Yet vk_load_info contained pointers to all these strings. This is wasteful and this commit changes it to avoid the latter two strings. This saves 6353B of strings, 1776 B of .data.rel.ro as well as 5328 B due to the removed relocations (corresponding to 2 * 111 removed pointers) in lavc/vulkan_decode.o alone (ff_vk_load_functions() is inlined in lavfi/vulkan_filter.c, lavu/hwcontext_vulkan.c and lavc_vulkan_decode.c, so the savings are three times this for shared builds; for static builds, the number may be smaller depending upon whether strings are deduplicated).

Lynne	358919506d	vulkan: enable VK_KHR_cooperative_matrix It's of interest to API users, and of interest to us, as a DCT/DST can be implemented via matrix multiplies.	1 year ago
