* panfrost: Refactor blend infrastructureAlyssa Rosenzweig2019-07-109-202/+455
| | | | | | | We would like to permit keying blend shaders against the framebuffer format, which requires some new blending abstractions. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/midgard: Use unsigned blend patch offsetAlyssa Rosenzweig2019-07-101-1/+1
| | | | | | | We would like the offset field to be unsigned, letting 0 represent "no offset" and positive represent an offset. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/midgard: Handle pure int formatsAlyssa Rosenzweig2019-07-101-14/+26
| | | | | | | | | | | | | I'm not sure I'm totally comfortable with this, but conceptually neither float nor pure-int formats require any format conversion, except size conversion. Going from a shaderable format (fp32 or i16, for instance) into a blendable format (fp16) is a separate question, one we can defer momentarily while we're not interested in actually blending. As an aside, I'd be fascinated by an integer-based blending implementation. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/mfbd: Handle pure int formatsAlyssa Rosenzweig2019-07-101-4/+16
| | | | | | | We see that the render target itself turns out to be typeless (surprise!) Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost/midgard: Implement preliminary float convertersAlyssa Rosenzweig2019-07-101-7/+33
| | | | | | | We'll need some careful handling, but for now, get some baseline code out for handling float formats in a blend shader. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost: Handle "blend disabled" blend shadersAlyssa Rosenzweig2019-07-101-12/+22
| | | | | | | | Normally, disabled blend can definitely be fixed-function'd away, but if a blend shader is used merely for format conversion rather than blending, this code path can be nevertheless hit. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost: Route format through fixed-function blendingAlyssa Rosenzweig2019-07-103-8/+51
| | | | | | Not all framebuffer formats are supported by the fixed-function blender. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost/midgard: Use Gallium framebuffer formatsAlyssa Rosenzweig2019-07-101-4/+37
| | | | | | | | | Ideally, we would keep Galliumisms far away from the compiler; unfortunately, Mesa hasn't standardized on system of format codes to be shared across APIs and across drivers, so using Gallium formats is our best bet in the short run. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/midgard: Use fp16 exclusively while blendingAlyssa Rosenzweig2019-07-102-9/+9
| | | | | | | | | We now have some preliminary fp16 support available. We're not able to expose this for GLSL quite yet, but for internal blend shaders, we're able to do control bitness ourselves just fine. So let's fp16 that stuff! Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/midgard: Remove opt_copy_prop_texAlyssa Rosenzweig2019-07-101-50/+0
| | | | | | | | Eventually this should be replaced by proper tex RA / not emitting so many silly moves to begin with / better general copy prop. For now remove it since it breaks things. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost/midgard: Hoist mask fieldAlyssa Rosenzweig2019-07-107-80/+70
| | | | | | | | | | Share a single mask field in midgard_instruction with a unified format, rather than using separate masks for each instruction tag with hardware-specific formats. Eliminates quite a bit of duplicated code and will enable vec8/vec16 masks as well (which don't map as cleanly to the hardware as we might like). Signed-off-by: Alyssa Rosenzweig <[email protected]>

| | | | | | | We can handle differing, but we'd prefer not to because there are restrictions on sizing which aren't accounted for yet. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost/midgard: NIRify blend load scale/convertAlyssa Rosenzweig2019-07-102-54/+8
| | | | | | | | The scale and type-convert can now be expressed in NIR, rather than MIR, which is significantly more maintainable and demonstrates correctness of the type conversion patches. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost/midgard: Implement upscaling type convertsAlyssa Rosenzweig2019-07-101-14/+59
| | | | | | | | Rather than using a dest_override, we upscale integers by using a half field with a sign-extend bit. A variant of this trick should also work for floats, but one step at a time! Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/midgard: Move blend load/store into NIRAlyssa Rosenzweig2019-07-102-78/+65
| | | | | | | | | We have dedicated intrinsics to access the raw contents of the tile buffer so we can use a dedicated NIR pass to lower appropriately for blend shaders, rather than introducing a bizarre hardcoded blend epilogue that only works for RGBA8_UNORM.

* panfrost/midgard: Implement integer downsize opsAlyssa Rosenzweig2019-07-102-3/+62
| | | | | | | | | | | | | | | | | | Oh, dear. No turning back now. We begin implementing non-32-bit types, using downsizing integer type conversions as the initial instructions. We implement them naively as type-converting moves; substantially more efficient operation is possible by copypropping the type conversion modifier, but this optimization is not implemented here. Size converting modifiers on Midgard allow an instruction to write to a destination 1/2 the size, or to read from a source 1/2 the size. If we need an extreme conversion (32-bit to 8-bit, for instance), multiple type converting ops are chained together, which here is handled via an algebraic pass.

* panfrost/midgard: Move scale from MIR to NIRAlyssa Rosenzweig2019-07-102-10/+7
| | | | | | | This begins the process of removing blend shader specific MIR into a more general NIR lowering pass for formats. Signed-off-by: Alyssa Rosenzweig <[email protected]>

* panfrost: Extend clear colour packingAlyssa Rosenzweig2019-07-104-26/+94
| | | | | | | | | | | Eventually, this will allow packing clear colours for all formats, including floating-point framebuffers, pure integer buffers, and special formats. Currently, a few of these formats are supported, and many more are handled through a generic Gallium colour packing path (which is not a perfect fit for the hardware, but works for many formats and is a sane default for the moment.) Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost/mfbd: Include codes for float framebuffersAlyssa Rosenzweig2019-07-101-1/+28
| | | | | | | | | We see the hardware doesn't actually support float framebuffers in the native sense -- rather, it just allows higher bpp framebuffers and lets a blend shader / additional clear_color fields sort out the formats. This will be.. interesting. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* panfrost: Prepare some code for MRTAlyssa Rosenzweig2019-07-101-26/+13
| | | | | | | | Full MRT support is a while away, but in the mean time, we can remove code that explicitly assumes nr_cbufs <= 0, to minimize the obstacles we'll face later when we add the whole thing. Signed-off-by: Alyssa Rosenzweig <[email protected]>

We don't want applications directly linking against libEGL_mesa.so (apps should always go through libEGL.so, regardless of who is providing it), so we shouldn't export any other symbols either.

* symbols-check: introduce new python scriptEric Engestrom2019-07-102-0/+116
| | | | | | | | | | | | | | | | | | | | I've re-written this in bash a couple times over the years, and then I realised python is much more portable and already required by Mesa, so we might as well make use of it. I decided to still use the build system's NM instead of re-implementing symbols extraction, to offload the complexity of keeping it compatible with many systems (Linux, Unix, BSD, MacOS, etc.), especially when cross-building. This new script checks not only that nothing is exported when it shouldn't be, but also that everything that should be exported is. Sometimes, some symbols _can_ be exported but don't have to be, in which case they can be prefixed with `(optional)`.
