Vulkan Descriptor Update Extensions Wired Up For Intel's ANV Driver

Intel's ANV Vulkan driver in Mesa Git has picked up support for two more extensions of this week's big Vulkan update.

Mesa Git now has support for VK_KHR_descriptor_update_template and VK_KHR_push_descriptor within the Intel ANV driver. These descriptor update extensions are a new way to update resource references between draw/compute dispatch calls. VK_KHR_push_descriptor allows descriptors to be written into the command buffer and VK_KHR_descriptor_update_template makes it easier to update a fixed set of descriptors.

Supporting these descriptor update extensions in the Intel open-source Vulkan driver code-base just amounted to a few hundred new lines of code. More details via the commits.

The Intel developers are rather prepared for Vulkan 1.0.42 and keeping their Linux driver implementation in-step with the latest Khronos API changes. One of the open matters though they are currently deciding is whether to land the "KHX" experimental extensions into mainline Mesa Git or keep them in a branch until they've been declared stable.
