【Vulkan】 Question About VK_EXT_fragment_density_map

Togchen

Hi,

About VK_EXT_fragment_density_map(VkPhysicalDeviceFragmentDensityMapFeaturesEXT) (registry.khronos.org/.../vkspec.html

when used VK_EXT_fragment_density_map , mali gpu (Device1 & Device2) has crashed In vkCmdEndRenderPass (crash stack in attachment , No Validation Error)，and Adreno  gpu (Device3) has succeed

Device1(mali)

  •  Oppo Reno5 Pro 5G
  •  GpuFamily：ARM Mali-G77 MC9
  •  AndroidVersion：12
  • GlVersion：OpenGL ES 3.2 v1.r32p1-01eac0.111ce79c0e85a639772bd634d9e734cf,) 
  • VulkanVersion: 1.1.177

Device2(mali)

  • GpuFamily: Mali-G77 MC9
  • AndroidVersion: 11
  • GlVersion: OpenGL ES 3.2 v1.r26p0-01eac0.bed3b8f44871361148086fa6397ba747
  • VulkanVersion: 1.1.131

Device3(Adreno)

  • vivo
  • GpuFamily: Adreno (TM) 660
  • AndroidVersion: 11
  • GlVersion: OpenGL ES 3.2 V@0525.0 (GIT@f7fceaaafa, I5121de8c99, 1605177106) (Date:11/12/20)
  • VulkanVersion: 1.1.128

Code Setting:

  1. VK_EXT_fragment_density_map be Supported （By vkEnumerateDeviceExtensionProperties）
  2. VkPhysicalDeviceFragmentDensityMapFeaturesEXT.fragmentDensityMap is true (By vkGetPhysicalDeviceFeatures2)
  3. When create device, I added extension VK_EXT_fragment_density_map (Supported By Device) (means VkDeviceCreateInfo.ppEnabledExtensionNames = "xxx"...,"VK_EXT_fragment_density_map",..."") & pNext to VkPhysicalDeviceFragmentDensityMapFeaturesEXT (means VkDeviceCreateInfo.pNext = ... &VkPhysicalDeviceFragmentDensityMapFeaturesEXT ....)

Is  Vulkan driver (mali)  bug ?
