* vc4: Add a flag in the screen to track control flow support.Eric Anholt2016-07-123-1/+14
| | | | | For now it's still always false, but I need it in place for kernel backwards compat support as I extend the backend for control flow.
* vc4: Define a QIR branch instructionEric Anholt2016-07-124-9/+61
| | | | | | This uses the branch condition code in inst->cond to jump to either successor[0] (condition matches) or successor[0] (condition doesn't match).
* 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 reduces how much we need to pass around as arguments, which was becoming more of a problem with looping validation.
* vc4: Add QPU support for generating BRANCH instructions.Eric Anholt2016-07-125-1/+85

* vc4: Print live variable start/ends during QIR dumping.Eric Anholt2016-07-121-0/+45
| | | | | 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.
* vc4: Convert vc4_opt_peephole_sf to work with control flow.Eric Anholt2016-07-121-4/+18
| | | | | | 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)
* vc4: Also enable phi elimination.Eric Anholt2016-07-121-0/+1
| | | | | | | | 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.
* vc4: fix memory leakEric Engestrom2016-07-121-1/+1

* vc4: Close our screen's fd on screen close.Eric Anholt2016-07-121-0/+3

* 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.

* clover: Move back to using build_error to signal compilation failure.Francisco Jerez2016-07-115-17/+17
| | | | | | | | | | | | | | This partially reverts 7e0180d57d330bd8d3047e841086712376b2a1cc. Having two different exception subclasses for compilation and linking makes it more difficult to share or move code between the two codepaths, because the exact same function under the same error condition would need to throw one exception or the other depending on what top-level API is being implemented with it. There is little benefit anyway because clCompileProgram() and clLinkProgram() can tell whether they are linking or compiling a program.
