* i965/fs: fix offset when loading double vector input varyingsSamuel Iglesias Gonsálvez2016-06-061-1/+21
| | | | | | | | | | | | | | | | | When we are not packing a double input varying, we might need to read its data in a non-aligned to 64-bit offset, so we read the wrong data. This is happening when using explicit locations in varyings because Mesa disables packing varying for that case. const_index is in 32-bit size units but offset() is multiplying it by destination type size units. When operating with double input varyings, const_index value could be not aligned to 64 bits. To fix it, we load the double vector as if it was a float based vector with twice the number of components.

* i965/vec4: Fix cmod propagation not to propagate non-identity cmod into CMP(N).Francisco Jerez2016-06-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | The conditional mod of these instructions determines the semantics of the comparison itself (rather than being evaluated based on the result of the instruction as is usually the case for most other instructions that allow conditional mods), so it's in general not legal to propagate a conditional mod into a CMP instruction. This prevents cmod propagation from (mis)optimizing: cmp.z.f0 tmp, ... mov.z.f0 null, tmp into: cmp.z.f0 tmp, ... which gives the negation of the flag result of the original sequence. I originally noticed this while working on SIMD32 in the scalar back-end, but the same scenario is likely to be possible in vec4 programs so this commit ports the bugfix with the same name from the scalar back-end to the vec4 cmod propagation pass.

* i965: Enable cross-thread constants and compact local IDs for hsw+Jordan Justen2016-06-013-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cross thread constant support appears on Haswell. It allows us to upload a set of uniform data for all threads without duplicating it per thread. One complication is that cross-thread constants are loaded into registers before per-thread constants. Previously, our local IDs were loaded before the uniform data and treated as 'payload' data, even though they were actually pushed into the registers like the other uniform data. Therefore, in this patch we simultaneously enable a newer layout where each thread now uses a single uniform slot for a unique local ID for the thread. This uniform is handled specially to make sure it is added last into the uniform push constant registers. This minimizes our usage of push constant registers, and maximizes our ability to use cross-thread constants for registers. To swap from the old to the new layout, we also need to flip some lowering pass switches to let our driver handle the lowering instead. We also no longer force thread_local_id_index to -1. v4: * Minimize size of patch that switches from the old local ID layout to the new layout (Jason) Cc: "12.0" <[email protected]> Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | We need information about push constants in a few places for the GL driver, and another couple places for the vulkan driver. When we add support for uploading both a common (cross-thread) set of push constants, combined with the previous per-thread push constant data, things are going to get even more complicated. To simplify things, we add push constant info into the cs prog_data struct. The cross-thread constant support is added as of Haswell. To support it we need to make sure all push constants with uniform values are added to earlier registers. The register that varies per thread and holds the thread invocation's unique local ID needs to be added last. For now we add the code that would calculate cross-thread constatn information for hsw+, but we force it (cross_thread_supported) off until the other parts of the driver support it. v4: * Support older local ID push constant layout as well.

It is important for this uniform to be added in the last push constant register. fs_visitor::assign_constant_locations is updated to make sure this happens.

| | | | | | | | | | | | | | | | | | We know that there cannot be any destination dependency race if we reach the beginning or end of the program without having found any other instruction the send could possibly race with. This avoids emitting a pile of useless moves at the beginning or end of the program in the most common case in which the program has a single basic block only. On the original i965 I get the following shader-db results: total instructions in shared programs: 3354165 -> 3215637 (-4.13%) instructions in affected programs: 3183065 -> 3044537 (-4.35%) helped: 13498 HURT: 0 Reviewed-by: Jason Ekstrand <[email protected]>
