* gallium: add PIPE_CAP_STREAM_OUTPUT_INTERLEAVE_BUFFERSIlia Mirkin2016-10-221-0/+1
| | | | | | | | | | | | | | This allows the driver to signal that it can't handle random interleaving of attributes across buffers. This is required for ARB_transform_feedback3, and it's initialized to whatever the previous value of PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME was except for nv50 where it is disabled. Note that the proprietary drivers never expose ARB_transform_feedback3 on any GT21x's (where nouveau previously did), and after some effort I was unable to get it to work.

* llvmpipe: Cap to 2 GB on 32 bitsAxel Davy2016-10-101-0/+6
| | | | | | | | | | | | | | On 32 bits system, application memory is quite limited. llvmpipe uses application memory. To help prevent memory exhaustion, limit reported memory availability to 2GB. Some gallium nine apps do check reported memory by allocating resources until memory is full. Gallium nine refuses allocations when 80% of the reported memory limit is used. This change helps some apps to start. Signed-off-by: Axel Davy <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>

* gallium: add a cap to expose whether driver supports mixed color/zs bitsIlia Mirkin2016-08-231-0/+1
| | | | | | | | | | Some hardware can't render to color/depth buffers of mixed bitness. When that happens a fallback has to happen, but this allows the driver to express that this isn't an optimal scenario. The purpose of this is to remove such fbconfigs from the GLX/EGL config list.

* llvmpipe: fix issues with depth clampRoland Scheidegger2016-08-203-49/+94
| | | | | | | | | | | | | | | | We only did depth clamp when the value was written from the fs. This is very wrong both for d3d10 and GL, and only passed the corresponding piglit test due to pure luck (it no longer does with the enhanced test). Also, interpolation clamped values to 1.0 always, which can legitimately happen if depth clip is disabled, so fix that as well (untested). There is one unresolved issue left, d3d10 always does depth clamping, whereas GL does not (but does [0,1] clamp instead for fs depth outputs) - this information isn't in any gallium state object, leave it as-is for now (though it looks like llvmpipe misses the [0,1] clamp as well). This (with the previous patch) fixes piglit depth-clamp-range test. Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: fix depth clamping wrt reversed near/far valuesRoland Scheidegger2016-08-201-9/+3
| | | | | | | | | | | This wasn't handled before (the result was that no matter what value got clamped, it always ended up as the near value in this case) (if clamping actually happened). Fix this by using the util helper for that (the math is otherwise "mostly" the same, mostly because there could actually be differences due to float rounding, but I don't even know which one would be more correct).

Some drivers only had 5. The goal is to have 1 indirect call for drivers that care. The resource type can be determined statically at most call sites.

* llvmpipe: hack-fix bugs due to bogus bind flagsRoland Scheidegger2016-06-146-17/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | The gallium contract would be that bind flags must indicate all possible bindings a resource might get used, but fact is the mesa state tracker does not set bind flags correctly, and this is more or less unfixable due to GL. This caused a bug with piglit arb_uniform_buffer_object-rendering-dsa since 6e6fd911da8a1d9cd62fe0a8a4cc0fb7bdccfe02 - the commit is correct, but it caused us to miss updates to fs UBOs completely, since the corresponding buffer didn't have the appropriate bind flag set (thus we wouldn't check if it is indeed currently bound). See the discussion about this starting here: https://lists.freedesktop.org/archives/mesa-dev/2016-June/119829.html So, update the bind flags when we detect such usage. Note we update this value for now only in places which matter for us - that is creating sampler/surface view, or binding constant buffer. There's plenty more places (setting streamout buffers, vertex/index buffers, ...) where things can be set with the wrong bind flags, but the bind flags there never matter. While here also make sure we only set dirty constant bit when it's a fs constant buffer - totally doesn't matter if it's vs/gs. Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | | | Some hardware supports primitive restart on patch primitives, and other hardware does not. Modern GL and ES include a query for this feature; adding a capability bit will allow us to answer it. As far as I know, AMD hardware does not support this feature, while NVIDIA and Intel hardware does. However, most Gallium drivers do not appear to support tessellation shaders yet.
