* mesa: reference built-in uniforms into gl_uniform_storageMartin Peres2015-06-0414-49/+73
| | | | | | | | | | | | | | | This change introduces a new field in gl_uniform_storage to explicitely say that a uniform is built-in. In the case where it is, no storage is defined to make it clear that it is read-only from the mesa side. I fixed all the places in the code that made use of the structure that I changed. Any place making a wrong assumption and using the storage straight away will just crash. This patch seems to implement the path of least resistance towards listing built-in uniforms in GL_ACTIVE_UNIFORM (and other APIs).

| | | | | | | | | | | | | | | | | | lower_phis_to_scalar() pass recurses the instruction dependence graph to determine if all the sources of a given instruction are scalarizable. To prevent cycles, it temporary marks the phi instruction before recursing in, then updates the entry with the resulting value. However, it does not consider that the entry value may have changed after a recursion pass, hence causing a use-after-free situation and a crash. This patch fixes this by reloading the entry corresponding to the 'phi' after recursing and before updating its value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation makes it pretty clear that we shouldn't use this: "Under normal conditions SW shall specify DMask, as the GS stage will provide a Dispatch Mask appropriate to SIMD4x2 or SIMD8 thread execution (as a function of dispatch mode). E.g., for SIMD4x2 execution, the GS stage will generate a Dispatch Mask that is equal to what the EU would use as the Vector Mask. For SIMD8 execution there is no known usage model for use of Vector Mask (as there is for PS shaders)." I also managed to find descriptions of DMask and VMask, in the "State Register" (sr0.2/3) field descriptions: "Dispatch Mask (DMask). This 32-bit field specifies which channels are active at Dispatch time." "Vector Mask (VMask). This 32-bit field contains, for each 4-bit group, the OR of the corresponding 4-bit group in the dispatch mask." SIMD4x2 shaders process one or two vec4 values, with each 4-bit group corresponding to xyzw channel enables (either all on, or all off). Thus, DMask = VMask in SIMD4x2 mode. But in SIMD8 mode, 4-bit groups are meaningless, so it just messes up your values. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ben Widawsky <[email protected]>

* i965: Don't add base_binding_table_index if it's zeroNeil Roberts2015-05-312-2/+4
| | | | | | | | | | | | | | | When calculating the binding table index for non-constant sampler array indexing it needs to add the base binding table index which is a constant within the generated code. Often this base is zero so we can avoid a redundant instruction in that case. It looks like nothing in shader-db is doing non-constant sampler array indexing so this patch doesn't make any difference but it might be worth having anyway.

* i965: Don't use a temporary when generating an indirect sampleNeil Roberts2015-05-312-26/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously when generating the send instruction for a sample instruction with an indirect sampler it would use the destination register as a temporary store. This breaks when used in combination with the opt_sampler_eot optimisation because that forces the destination to be null. This patch fixes that by avoiding the temp register altogether. The reason the temporary register was needed was because it was trying to ensure the binding table index doesn't overflow a byte by and'ing it with 0xff. The result is then or'd with samper_index<<8. This patch instead just and's the whole thing by 0xfff. This will ensure that a bogus sampler index won't overflow into the rest of the message descriptor but unlike the previous code it won't ensure that the binding table index doesn't overflow into the sampler index. It doesn't seem like that should matter very much though because if the shader is generating a bogus sampler index then it's going to just get garbage out either way. Instead of doing sampler_index<<8|(sampler_index+base_table_index) the new code avoids one operation by doing sampler_index*0x101+base_table_index which should be equivalent. However if we wanted to avoid the multiply for some reason we could do this by adding an extra or instruction still without needing the temporary register.

| | | | | | | | | | | | | We were returning the most recently freed BO, without checking if it was idle yet. This meant that we generally stalled immediately on the previous frame when generating a new one. Instead, allocate new BOs when the *oldest* BO is still busy, so that the cache scales with how much is needed to keep some frames outstanding, as originally intended. Note that if you don't have some throttling happening, this means that you can accidentally run the system out of memory. The kernel is now applying some throttling on all execs, to hopefully avoid this.

* i965: Disable compaction for EOT send messagesBen Widawsky2015-05-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | AFAICT, there is no real way to make sure a send message with EOT is properly ignored from compact, nor can I see a way to actually encode EOT while compacting. Before the single send optimization we'd always bail because we hit the is_immediate && !is_compactable_immediate case. However, with single send, is_immediate is not true, and so we end up trying to compact the un-compactible. Without this, any compacting single send instruction will hang because the EOT isn't there. I am not sure how I didn't hit this when I originally enabled the optimization. I didn't check if some surrounding code changed. I know Neil and Matt were both looking into this. I did a quick search and didn't see any patches out there to handle this. Please ignore if this has already been sent by someone. (Direct me to it and I will review it).
