v-2018.Q4.3

Driver installation instruction

2018-12-4 update

New feature and improvement

• Enable VK_EXT_scalar_block_layout extension
• Enable VK_KHR_swapchain_mutable_format extension
• Enable on-chip GSVS ring on GFX9, seeing up to 10% performance gain
• Add dccBitsPerPixelThreshold setting
• Re-enable tracing of missing registers in thread trace
• Remove some useless settings

Issue fix

• Undefined reference to vk::OverrideDispatchTable_ND(vk::DispatchTable*)
• Errors with multiple monitors and direct display
• dEQP-VK.api.device_init.create_instance_device_intentional_alloc_fail test failure
• Crash issue on Raven caused by the implementation of VK_AMD_memory_overallocation_behavior extension
• dEQP-VK.glsl.atomic_operations.*signed64bit failure on gfx7
• ELEX crash with Steam Proton
• CopyTextureRegion failure when copying a MSAA Resource in D32_FLOAT or D16_UNORM to a R32_UINT format
• GFX9: CB_DCC_CONTROL register is programmed incorrectly
• Perf counter instance incorrect calculation

v-2018.Q4.2

Driver installation instruction

2018-11-19 update

New feature and improvement

• Enable sparse support by default
• Enable VK_AMD_memory_overallocation_behavior extension
• Enable degenerate triangles for conservative rasterizations
• Add setting for exiting after compilation failure
• Add setting CsCuEnLimitMask for limiting CUs enabled for compute shaders
• Add the ability to dump debug stack traces
• Set default -log-file-dbgs to "" (meaning stderr): this brings amdllpc into line with other LLVM tools

Issue fix

• Can't clear a mutable format image
• CTS memory.pipeline_barrier.transfer_dst_storage_image tests fail
• MGPU asserts when creating graphics pipeline
• Wrong target device ID passed to PAL
• Dual source bend is being enabled when blending is disabled
• Regression dEQP-VK.wsi.wayland.swapchain.create.min_image_count test crashes
• Dependency on x11/xcb libraries even there is no x11/xcb surface created
• Assert in dEQP-VK.binding_model.descriptorset_random.*

v-2018.Q4.1

Driver installation instruction

2018-11-8 update

New feature and improvement

• Tidy amdllpc's use of spvgen
• amdllpc switched to using static vfx library
• amdllpc remove need for -auto-layout-desc option
• New amdllpc -verify-ir option: this option adds a verify pass after each pass in the LLPC compilation process
• Add panel setting for debugging shader
• Refine wayland window system support

Issue fix

• CB_DCC_CONTROL register is programmed incorrectly
• Barrier secondary buffer test failure
• Empty perf traces under gfx9
• external_memory_host.bind_image_memory_and_render tests failing on Vega10
• GFX9's hardware specific CmdBarrier functions forget to call its base function
• [GpuProfiler] ThreadTraceViewer CRCs for full frame captures
