* loader: ifdef libdrm specific code and includeEmil Velikov2014-01-195-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | Mesa provides the flexibility of building without the need to have libdrm present on the system. The situation has regressed with the recent commit commit 8c2e7fd8460750543367053b1be9368cc38e1d6a Author: Emil Velikov <[email protected]> Date: Fri Jan 10 23:36:16 2014 +0000 loader: introduce the loader util lib By isolating libdrm code by #ifndef __NOT_HAVE_DRM_H we can have libdrm-less builds on across all build systems. This patch converts Android's _EGL_NO_DRM to __NOT_HAVE_DRM_H to provide consistency with the other cases within mesa, allows compilation of libloader on libdrm-less scons and conditionally links against libdrm if present under automake.

* i965: Add a new representation for Broadwell shader instructions.Kenneth Graunke2014-01-184-0/+835
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Broadwell significantly changes the EU instruction encoding. Many of the fields got moved to different bit positions; some even got split in two. With so many changes, it was infeasible to continue using struct brw_instruction. We needed a new representation. This new approach is a bit different: rather than a struct, I created a class that has four DWords, and helper functions that read/write various bits. This has several advantages: 1. We can create several different names for the same bits. For example, conditional modifiers, SFID for SEND instructions, and the MATH instruction's function opcode are all stored in bits 27:24. In each situation, we can use the appropriate setter function: set_sfid(), set_math_function(), or set_cond_modifier(). This is much easier to follow. 2. Since the fields are expressed using the original 128-bit numbers, the code to create the getter/setter functions follows the table in the documentation very closely. To aid in debugging, I've enabled -fkeep-inline-functions when building gen8_instruction.c. Otherwise, these functions cannot be called by gdb, making it insanely difficult to print out anything. Kenneth Graunke wrote most of this code. Damien Lespiau ported it to C99. Xiang Haihao added media fields. Zhao Yakui added indirect addressing support. Eric Anholt added an assertion to make sure that values fit in the alloted number of bits. v2: Update for brw_reg_type_to_hw_type(), which necessitates passing brw_context pointers around everywhere.

| | | | | | | | | | | | | | | | | | | | | | OpenGL does whole-point clipping, that is a large point is either fully clipped or fully unclipped (the latter means it may extend beyond the viewport as long as the center is inside the viewport). d3d9 (d3d10 has no large points) however requires points to be clipped after they are expanded to a rectangle. (Note some IHVs are known to ignore GL rules at least with some hw/drivers.) Hence add a rasterizer bit indicating which way points should be clipped (some drivers probably will always ignore this), and add the draw interaction this requires. Drivers wanting to support this and using draw must support large points on their own as draw doesn't implement vp clipping on the expanded points (it potentially could but the complexity doesn't seem warranted), and the driver needs to do viewport scissoring on such points.

* llvmpipe: do constant buffer bounds checking in shadersZack Rusin2014-01-169-43/+174
| | | | | | | | | | | | | | | | | | | | It's possible to bind a smaller buffer as a constant buffer, than what the shader actually uses/requires. This could cause nasty crashes. This patch adds the architecture to pass the maximum allowable constant buffer index to the jit to let it make sure that the constant buffer indices are always within bounds. The behavior follows the d3d10 spec, which says the overflow should always return all zeros, and overflow is only defined as access beyond the size of the currently bound buffer. Accesses beyond the declared shader constant register size are not considered an overflow and expected to return garbage but consistent garbage (we follow the behavior which some wlk tests expect which is to return the actual values from the bound buffer).
