Description Mark Janes 2016-07-07 19:51:52 UTC
The following tests fail on 32 bit platforms:

Nanley has investigated this and is working on Mesa and Crucible fixes.  This bug tracks that work.
Comment 1 Nanley Chery 2016-08-12 21:59:30 UTC
With the patches just pushed to master, the following tests should be fixed:

The 5-patch series that fixes the test ends with

    func.desc.dynamic: Use a correct reference image
    Commit 17685f385bad0f7e79772e2e5990e2e2572b6897 changed the uniform buffer
    test's reference image although the test logic would have generated the
    same image if it didn't have the bugs that commit introduced. Restore the
    original image.
    Since storage test's output is equivalent to that of the uniform test,
    remove its custom image and reference the uniform buffer test's image.

I'll look into func.first once I setup a 32-bit system.
Comment 2 Nanley Chery 2016-10-24 21:58:45 UTC
Thanks to some help from Jason I was able to get a 32-bit build of crucible on my 64-bit system with the following command:

 ./configure CC="gcc -m32" --build=x86_64-pc-linux-gnu --host=i686-pc-linux-gnu

It seems that func.first started passing with the following commit:

    Conform to Vulkan Specification 1.0.20

    I used the Vulkan Validation layers to determine the areas of

     * Provide required fields:
       - VkFramebufferCreateInfo::renderPass
       - VkSubmitInfo::sType
       - VkDeviceQueueCreateInfo::sType
       - VkDeviceQueueCreateInfo::pQueuePriorities
     * Assign the right bit to VkDescriptorPoolCreateInfo::flags for the
       freeing which occurs during cleanup.
     * Use the correct VkDescriptorPoolCreateInfo::poolSizeCount value.
       This fixes a bug in DescriptorPool creation in which DescriptorTypes
       after STORAGE_TEXEL_BUFFER were not being added to the pool.
     * Set VkGraphicsPipelineCreateInfo::pDynamicState to NULL if
       VkPipelineDynamicStateCreateInfo::dynamicStateCount is zero
