* broadcom/compiler: Set up passthrough Z when doing FS discards.Eric Anholt2017-10-103-2/+15
| | | | | | | | In order to keep early-Z from writing early in a discard shader, you need to set the "modifies Z" bit in the shader state (which the new prog_data.discards will indicate). Then, in the shader we do a TLB write to make Z passthrough happen (the QPU result is ignored, so we use a NULL source).
* broadcom/compiler: Don't forget the discard state on TLB Z writes.Eric Anholt2017-10-101-0/+1
| | | | We don't want to write Z for discarded fragments.
* broadcom/compiler: Use defines instead of magic values in TLB write setup.Eric Anholt2017-10-101-6/+33

* broadcom/xml: Add the vc5 Base Vertex/Base Instance packet.Eric Anholt2017-10-101-0/+6
| | | | This lets us do index_bias and ARB_base_instance.
* broadcom/xml: Add a bunch more vc5 tile list management packets.Eric Anholt2017-10-101-0/+60
| | | | We're going to need these for MSAA, and to use the generic per-tile list.
* broadcom/xml: Remove vc5 base packet for tile bin/render mode config.Eric Anholt2017-10-101-10/+0
| | | | | | These existed so I could unpack just the sub-id field to switch on in the old manual CLIF dumper. The new codegen handles sub-id automatically, but only if these stub packets aren't there with an implicit sub-id=0.
* braodcom/xml: Fix a pasteo in vc5 store tile buffer general.Eric Anholt2017-10-101-1/+1

* broadcom: Add VC5 NIR compiler.Eric Anholt2017-10-1017-0/+7498
| | | | | | | | | | | This is a pretty straightforward fork of VC4's NIR compiler to VC5. The condition codes, registers, and I/O have all changed, making the backend hard to share, though their heritage is still recognizable. v2: Move to src/broadcom/compiler to match intel's layout, rename more "vc5" to "v3d", rename QIR to VIR ("V3D IR") to avoid symbol conflicts with vc4, use new v3d_debug header, add compiler init/free functions, do texture swizzling in NIR to allow optimization.
* broadcom: Add vc5 CLIF dumpingEric Anholt2017-10-103-0/+312
| | | | | | | | This will be usable with "VC5_DEBUG=cl" on the vc5 driver to stream a CLIF file (the Broadcom equivalent of i965's AUB) to stderr. I haven't tested that this is actually usable with the internal CLIF-consuming tools, but is close enough as a baseline and is useful for visually inspecting the command stream.
* broadcom: Add V3D 3.3 QPU instruction pack, unpack, and disasm.Eric Anholt2017-10-1012-0/+2774
| | | | | | | | | | | | | | | | | Unlike VC4, I've defined an unpacked instruction format with pack/unpack functions to convert to 64-bit encoded instructions. This will let us incrementally put together our instructions and validate them in a more natural way than the QPU_GET_FIELD/QPU_SET_FIELD used to. The pack/unpack unfortuantely are written by hand. While I could define genxml for parts of it, there are many special cases (like operand order of commutative binops choosing which binop is being performed!) and it probably wouldn't come out much cleaner. The disasm unit test ensures that we have the same assembly format as Broadcom's internal tools, other than whitespace changes. v2: Fix automake variable redefinition complaints, add test to .gitignore
* broadcom: Introduce a v3d_debug.h header for vc5 and broadcom Vulkan.Eric Anholt2017-10-103-0/+173
| | | | | | | Unlike vc4, where the compiler and gallium driver live together, for vc5 the compiler will live up in the shared broadcom directory, and need access to the debug flags. Define a set of debug flags and helpers there, so it can be shared between compiler, vc5, and vulkan.
* broadcom: Fix out-of-tree build include pathDaniel Stone2017-10-051-1/+3
| | | | | Reviewed-by: Eric Anholt <[email protected]> Fixes: 5b102160ae ("broadcom/genxml: Introduce a V3D packet/struct decoder.")
* broadcom/genxml: Set up enums for VC5 blending, depth, stencil, and prims.Eric Anholt2017-09-191-46/+77
| | | | | These will be used in tables in the Vulkan driver, and give us pretty CLIF dump output.
* broadcom/genxml: Add support for enum-typed fields.Eric Anholt2017-09-191-3/+13
| | | | | This basically comes from the intel genxml script. This will help improve gdb and CLIF output once we convert fields over.
* broadcom/genxml: Add V3D 3.3 packet definitions.Eric Anholt2017-08-183-0/+802
| | | | | This will be used by the new vc5 gallium driver, and a future Vulkan driver.
* broadcom/genxml: Check the sub-id field when decoding instructions.Eric Anholt2017-08-181-5/+26
| | | | | | VC5 introduces packet variants where the same opcode has behavior that is decided by a sub-id field in the early bits of the packet. Keep iterating over packets until we find the one with the matching sub-id.
* broadcom/genxml: Emit code for default headers for structs as well.Eric Anholt2017-08-181-14/+13
| | | | | | In the vc5 NIR backend, I want to use the XML code-generation to set up pack/unpack of structs for the texture uniforms, and setting up the unpacked copy needs a default header.
* broadcom: Add v3d_xml.h to gitignore.Eric Anholt2017-08-151-0/+1

* broadcom: Add missing libexpat cflags for the decoder.Eric Anholt2017-08-151-0/+3
| | | | | The Raspbian ARMv6 cross compiler wasn't picking up my (amd64) system copy of the header the way that the system gcc and armhf cross-compile did.
* broadcom/vc4: Switch the V3D 2.1 XML over to restricted address fields.Eric Anholt2017-07-251-4/+4
| | | | | | This keeps the flags out of v3d_decode.c's output. In the generated code, only the unpack functions see any change (where they now get the restricted start value), and vc4 doesn't use the unpack functions yet.
* broadcom/genxml: Support address fields with <32 bitsEric Anholt2017-07-251-1/+1
| | | | | | | | | | I was writing the XML such that the address field overlapped various flags in the alignment bits, which caused pain when trying to unpack for decode. Instead, keep the XML matching the docs (address fields don't overlap), and just infer the appropriate shift value during decode. During pack, the address is just applied to the appropriate bits already, ignoring the sub-byte start/end fields.
* broadcom/vc4: Switch the Viewport Center fields to a fixed-point representation.Eric Anholt2017-07-251-2/+2
| | | | | | This gets us automatic CL decoding to a floating-point value, and drops a magic number from the emit code. 250x250 shader runner tests now say they have a center of 125.0 instead of 2000.
* broadcom/genxml: Introduce a V3D packet/struct decoder.Eric Anholt2017-07-259-0/+1066
| | | | | | | This is copied from Intel's XML decoder, modified to handle V3D's byte-oriented packets. v2: Squash in robher's fixes for Android

| | | | | This was an oversight in the original XML support, because unpacking wasn't used much. The new XML-based CL dumper will want it, though.

* vc4: Introduce XML-based packet header generation like Intel's.Eric Anholt2017-06-309-0/+1133
I really liked this idea, as it should help with management of packet parsing tools like the CL dump. The python script is forked off of theirs because our packets are byte-based instead of dwords, and the changes to do so while avoiding performance regressions due to unaligned accesses were quite invasive. v2: Fix Android.mk paths, drop shebang for python script, fix overlap detection.
