* i965/blorp: Cleanup leftovers from push constant disablingTopi Pohjolainen2016-07-132-65/+12
| | | | | | | | | Setup for pixel shader push constants is the same as for other stages. Note that on gen8+ the if-else branches were identical and the generation check for packet size redundant. Signed-off-by: Topi Pohjolainen <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* i965/blorp/gen7+: Bring back push constant setupTopi Pohjolainen2016-07-132-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is partial revert of commit cc2d0e64. It looks that even though blorp disables a stage the corresponding 3DSTATE_CONSTANT_XS packet is needed to be programmed. Hardware seems to try to fetch the constants even for disabled stages. Therefore care needs to be taken that the constant buffer is set up properly. Blorp will continue to trash it into non-existing such as before. It is possible that this could be omitted on SKL where the constant buffer is considered when the corresponding binding table settings are changed. Bspec: "The 3DSTATE_CONSTANT_* command is not committed to the shader unit until the corresponding (same shader) 3DSTATE_BINDING_TABLE_POINTER_* command is parsed." However, as CONSTANT_XS packet itself does not seem to stall on its own, it is safer to emit the packets for SKL also. Possible alternative to blorp trashing could have been to setup defaults in the beginning of each batch buffer. However, hardware doesn't seem to tolerate these packets being programmed multiple times per primitive. Bspec for IVB: "It is invalid to execute this command more than once between 3D_PRIMITIVE commands."

| | | | | | | | | | | | So far we only used instructions with this size in situations where we did not operate per-channel and we wanted to ignore the execution mask, but gen7 fp64 will need to emit code with a width of 4 that needs normal execution masking. v2: - Modify the assert instead of deleting it (Curro) Reviewed-by: Francisco Jerez <[email protected]>
* i965/fs/gen7: split instructions that run into exec masking bugsIago Toral Quiroga2016-07-131-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In fp64 we can produce code like this: mov(16) vgrf2<2>:UD, vgrf3<2>:UD That our simd lowering pass would typically split in instructions with a width of 8, writing to two consecutive registers each. Unfortunately, gen7 hardware has a bug affecting execution masking and as a result, the second GRF register write won't work properly. Curro verified this: "The problem is that pre-Gen8 EUs are hardwired to use the QtrCtrl+1 (where QtrCtrl is the 8-bit quarter of the execution mask signals specified in the instruction control fields) for the second compressed half of any single-precision instruction (for double-precision instructions it's hardwired to use NibCtrl+1, at least on HSW), which means that the EU will apply the wrong execution controls for the second sequential GRF write if the number of channels per GRF is not exactly eight in single-precision mode (or four in double-float mode)." In practice, this means that we cannot write more than one consecutive GRF in a single instruction if the number of channels per GRF is not exactly eight in single-precision mode (or four in double-float mode). This patch makes our SIMD lowering pass split this kind of instructions so that the split versions only write to a single register. In the example above this means that we split the write in 4 instructions, each one writing 4 UD elements (width = 4) to a single register. v2 (Curro): - Make explicit that the thing about hardwiring NibCtrl+1 for the second compressed half is known to happen in Haswell and the issue with IVB might not be exactly the same. - Assign max_width instead of returning early so that we can handle multiple restrictions affecting to the same instruction. - Avoid division by 0 if the instruction does not write any registers. - Ignore instructions what have WE_all set. - Use the instruction execution type size instead of the dst type size. v3 (Curro): - Move the implementation down so it is not placed in the middle of another workaround. - Declare channels_per_grf as const. - Don't break the loop early if we find a BAD_FILE source. - Fix the number of channels that the hardware shifts for the second half of a compressed instruction to be 8 in single precision and 4 in double precision.

| | | | | | | | | | | | | | | | | | | Gen7 hardware does not support double immediates so these need to be moved in 32-bit chunks to a regular vgrf instead.

| | | | | | | Previously, there were occasionally NIR registers in our programs, but they were always actually used SSA-only. Now that we're trying to support control flow, we need to actually conditionally move to registers based on whether channels are active or not.

* vc4: Add kernel support for branching in shader validation.Eric Anholt2016-07-123-17/+280
| | | | | | | | | | | | | | | | | | | | | We're already checking that branch instructions are within the contents of the shader and the proper PROG_END sequence is present. The other thing we need in the presence of branching is to verify that the shader doesn't overflow past the end of the uniforms stream. To do that, we require that at the start of any basic block reading uniforms have the following instructions: load_imm temp, <offset within uniform stream> add unif_addr, temp, unif The instructions are generated by userspace, and the kernel verifies that the load_imm is of the expected offset, and that the add adds it to a uniform. We track which uniform in the stream that is, and at draw call time fix up the uniform stream to have the address of the start of the shader's uniforms for that draw call.

* vc4: Add a bitmap of branch targets in kernel validation.Eric Anholt2016-07-123-2/+133
| | | | | | This isn't used yet, it's just a first step toward loop validation. During the main parsing of instructions, we need to know when we hit a new basic block so that we can reset validated state.
* vc4: Track the current instruction into the validation_state.Eric Anholt2016-07-121-24/+30

| | | | | This only happens when live variables are set up, which is not in the normal dump, but is set up when we've failed to register allocate.
* vc4: Implement live intervals using a CFG.Eric Anholt2016-07-126-39/+393
| | | | | Right now our CFG is always a trivial single basic block, but that will change when enable loops.
* vc4: Make vc4_qir_schedule handle each block in the program.Eric Anholt2016-07-121-14/+23
| | | | | | | | Basically we just treat each block independently. The only inter-block scheduling I can think of that would be be interesting would be to move texture result collection to after a short loop/if block that doesn't do texturing. However, the kernel disallows that as part of its security validation.
* vc4: Convert uniforms lowering to work with multiple blocks.Eric Anholt2016-07-121-29/+44
| | | | | | | | | We still decide which uniform to lower based on how many instructions-that-need-lowering use that uniform, but now we emit a new temporary uniform load in each of the basic blocks containing an instruction being lowered. This commit is best reviewed with diff -b.

| | | | | | We need to apply the peephole pass to each of the blocks in the program. We don't do dataflow analysis for SF across blocks, but we also don't generate code that would need us to do so.
* vc4: Create a basic block structure and move the instructions into it.Eric Anholt2016-07-126-20/+122
| | | | | | | The optimization passes and scheduling aren't actually ready for multiple blocks with control flow yet (as seen by the "cur_block" references in them instead of iterating over blocks), but this creates the structures necessary for converting them.
* vc4: Add a "qir_for_each_inst_inorder" macro and use it in many places.Eric Anholt2016-07-1212-14/+17
| | | | | | | | We have the prior list_foreach() all over the code, but I need to move where instructions live as part of adding support for control flow. Start by just converting to a helper iterator macro. (The simpler "qir_for_each_inst()" will be used for the for-each-inst-in-a-block iterator macro later)

| | | | | | | | This avoids a bunch of code gen regressions when enabling loops in vc4. Prior to that, the GLSL that would have generated these optimizable phi nodes was being lowered to csels between either (undef, a) or (a, a), and those were being dealt with by nir_opt_undef and nir_opt_algebraic.

* st/omx/dec: convert decoder video buffer to progressiveLeo Liu2016-07-122-3/+68
| | | | | | | | | | | | | | | | | | | | | | with encode tunneling The idea of encode tunneling is to use video buffer directly for encoder, but currently the encoder doesn’t support interlaced surface, the OMX decoder set progressive surface before on that purpose. Since now we are polling the driver for interlacing information for decoder, we got the interlaced as preferred as other APIs(VDPAU, VA-API), thus breaking the transcode with tunneling. The solution is when with tunnel detected, re-allocate progressive target buffers, and then converting the interlaced decoder results to there. This has been tested with transcode results bit to bit matching as before with surface from progressive to progressive.
