* intel/device: make internal functions privateMark Janes2019-08-012-84/+68
| | | | | | | | | | | | | The device info initializer makes several fuctions internal: - handling of device override - updating topology from kernel information The implementation file is slightly reordered due to the renamed functions being static.

| | | | | | | | | | | | | | | | | | Rename the original device info initialization routine so callers don't mistakenly call the wrong one: gen_get_device_info_from_fd: Queries kernel for full device info, including topology details. gen_get_device_info_from_pci_id: Partially initializes device info based on PCI ID lookup, when the kernel is not available.

* i965: Move device info initialization to common codeMark Janes2019-08-012-0/+137
| | | | | | | | | | | With perf queries, initializing the device info is much more complex than just getting a PCI ID and calling gen_get_device_info. This commit adds a new gen_get_device_info_from_fd helper in common code which does all of the requisite kernel queries to get device info including all of the topology information.

* iris: Implement INTEL_DEBUG=pc for pipe control logging.Kenneth Graunke2019-06-202-0/+2
| | | | | | | | This prints a log of every PIPE_CONTROL flush we emit, noting which bits were set, and also the reason for the flush. That way we can see which are caused by hardware workarounds, render-to-texture, buffer updates, and so on. It should make it easier to determine whether we're doing too many flushes and why.

* intel/compiler: Implement TCS 8_PATCH mode and INTEL_DEBUG=tcs8Kenneth Graunke2019-05-142-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our tessellation control shaders can be dispatched in several modes. - SINGLE_PATCH (Gen7+) processes a single patch per thread, with each channel corresponding to a different patch vertex. PATCHLIST_N will launch (N / 8) threads. If N is less than 8, some channels will be disabled, leaving some untapped hardware capabilities. Conditionals based on gl_InvocationID are non-uniform, which means that they'll often have to execute both paths. However, if there are fewer than 8 vertices, all invocations will happen within a single thread, so barriers can become no-ops, which is nice. We also burn a maximum of 4 registers for ICP handles, so we can compile without regard for the value of N. It also works in all cases. - DUAL_PATCH mode processes up to two patches at a time, where the first four channels come from patch 1, and the second group of four come from patch 2. This tries to provide better EU utilization for small patches (N <= 4). It cannot be used in all cases. - 8_PATCH mode processes 8 patches at a time, with a thread launched per vertex in the patch. Each channel corresponds to the same vertex, but in each of the 8 patches. This utilizes all channels even for small patches. It also makes conditions on gl_InvocationID uniform, leading to proper jumps. Barriers, unfortunately, become real. Worse, for PATCHLIST_N, the thread payload burns N registers for ICP handles. This can burn up to 32 registers, or 1/4 of our register file, for URB handles. For Vulkan (and DX), we know the number of vertices at compile time, so we can limit the amount of waste. In GL, the patch dimension is dynamic state, so we either would have to waste all 32 (not reasonable) or guess (badly) and recompile. This is unfortunate. Because we can only spawn 16 thread instances, we can only use this mode for PATCHLIST_16 and smaller. The rest must use SINGLE_PATCH. This patch implements the new 8_PATCH TCS mode, but leaves us using SINGLE_PATCH by default. A new INTEL_DEBUG=tcs8 flag will switch to using 8_PATCH mode for testing and benchmarking purposes. We may want to consider using 8_PATCH mode in Vulkan in some cases. The data I've seen shows that 8_PATCH mode can be more efficient in some cases, but SINGLE_PATCH mode (the one we use today) is faster in other cases. Ultimately, the TES matters much more than the TCS for performance, so the decision may not matter much. Reviewed-by: Jason Ekstrand <[email protected]>

* i965: perf: query topologyLionel Landwerlin2018-03-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the introduction of asymmetric slices in CNL, we cannot rely on the previous SUBSLICE_MASK getparam to tell userspace what subslices are available. We introduce a new uAPI in the kernel driver to report exactly what part of the GPU are fused and require this to be available on Gen10+. Prior generations can continue to rely on GETPARAM on older kernels. This patch is quite a lot of code because we have to support lots of different kernel versions, ranging from not providing any information (for Haswell on 4.13 through 4.17), to being able to query through GETPARAM (for gen8/9 on 4.13 through 4.17), to finally requiring 4.17 for Gen10+. This change stores topology information in a unified way on brw_context.topology from the various kernel APIs. And then generates the appropriate values for the equations from that unified topology. v2: Move slice/subslice masks fields to gen_device_info (Rafael) v3: Add a gen_device_info_subslice_available() helper (Lionel) Signed-off-by: Lionel Landwerlin <[email protected]> Acked-by: Rafael Antognolli <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

It's also a requirement for CNL as this platform has asymetric subslices and the first method SUBSLICE_MASK value is assumed uniform across slices. v2: Change gen_device_info_update_from_masks() to generate topology and call into gen_device_info_update_from_topology (Lionel/Ken) Signed-off-by: Lionel Landwerlin <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
