| | | | | | | | | | | | GL_ARB_separate_shader_objects adds the ability to specify location layouts for interstage inputs and outputs. In addition, this extension makes 'in' and 'out' generally available for shader inputs and outputs. This mimics the behavior of GL_ARB_explicit_attrib_location.

* i965: Create a hardware context before initializing state module.Kenneth Graunke2014-02-201-6/+6
| | | | | | | | | | | | | | | | | | | | | brw_init_state() calls brw_upload_initial_gpu_state(). If hardware contexts are enabled (brw->hw_ctx != NULL), this will upload some initial invariant state for the GPU. Without hardware contexts, we rely on this state being uploaded via atoms that subscribe to the BRW_NEW_CONTEXT bit. Commit 46d3c2bf4ddd227193b98861f1e632498fe547d8 accidentally moved the call to brw_init_state() before creating a hardware context. This meant brw_upload_initial_gpu_state would always early return. Except on Gen6+, we stopped uploading the initial GPU state via state atoms, so it never happened. Fixes a regression since 46d3c2bf4ddd227193b98861f1e632498fe547d8.

* i965: Store absolute thread count in max_wm_threads on Broadwell.Kenneth Graunke2014-02-202-2/+5
| | | | | | | | | | | | | | | | | | In the past, 3DSTATE_PS took an absolute number of threads. Conversely, on Broadwell you always program 64, and it implicitly scales based on the GT-level with no special programming. So, I stored 64 in brw_device_info::max_wm_threads. However, I didn't realize that we also use max_wm_threads to compute the size of the scratch space buffer. In that case, we really need the absolute number of threads. This patch hardcodes 3DSTATE_PS to use the value it expects, and changes max_wm_threads back to a (completely fake) absolute thread count (once again copied from Haswell).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the latest documentation, any PIPE_CONTROL with the "Command Streamer Stall" bit set must also have another bit set, with five different options: - Render Target Cache Flush - Depth Cache Flush - Stall at Pixel Scoreboard - Post-Sync Operation - Depth Stall I chose "Stall at Pixel Scoreboard" since we've used it effectively in the past, but the choice is fairly arbitrary. Implementing this in the PIPE_CONTROL emit helpers ensures that the workaround will always take effect when it ought to. Apparently, this workaround may be necessary on older hardware as well; for now I've only added it to Broadwell as it's absolutely necessary there. Subsequent patches could add it to older platforms, provided someone tests it there. v2: Only flag "Stall at Pixel Scoreboard" when none of the other bits are set (suggested by Ian Romanick). v3: Prefix the function with "gen8" (requested by Eric).

By merging layout qualifiers into state->in_qualifier, we allow multiple input qualifiers. For example, the primitive type can be specified specified separately from the invocations count (ARB_gpu_shader5). state->gs_input_prim_type is moved into state->in_qualifier->prim_type state->gs_input_prim_type_specified is still processed separately so we can determine when the input primitive is specified.

* gallivm: add smallfloat to float conversion not relying on cpu denorm handlingRoland Scheidegger2014-02-201-20/+65
| | | | | | | | | | | | | | | | | | | | | | The previous code relied on cpu denorm support for converting small float formats (such r11g11b10_float and r16_float) to floats, otherwise denorms are flushed to zero. We worked around that in llvmpipe blend code by reenabling denorms, but this did nothing for texture sampling. Now it would be possible to reenable it there too but I'm not really a fan of messing with fpu flags (and it seems we can't actually do it reliably with llvm in any case looking at some bug reports). (Not to mention if you actually have a lot of denorms in there, you can expect some order-of-magnitude slowdown with x86 cpus.) So instead use code which adjusts exponents etc. directly hence not relying on cpu denorm support for the rescaling mul. (We still need the fpu flag handling as we can't do float-to-smallfloat without using cpu denorms at least for now - I actually wanted to keep both the old and new code and using one or the other depending on from where it's called but that didn't work out as the parameter would have to be passed through too many layers than I'd like.)

| | | | | | | | | | | | | | | | | According to the "Point Multisample Rasterization" of the OpenGL specification (3.0 or later), smooth points are supposed to be enabled implicitly when multisampling, regardless of the GL_POINT_SMOOTH flag. However, if GL_POINT_SPRITE is enabled, you get square points no matter what. Core contexts always enable point sprites, so this effectively makes smooth points go away, even in the case of multisampling. Fixes Piglit's EXT_framebuffer_multisample/point-smooth tests.
