2008-10-03 | CELL: changes to generate SPU code for stenciling | Robert Ellison | |
This set of code changes are for stencil code generation support. Both one-sided and two-sided stenciling are supported. In addition to the raw code generation changes, these changes had to be made elsewhere in the system: - Added new "register set" feature to the SPE assembly generation. A "register set" is a way to allocate multiple registers and free them all at the same time, delegating register allocation management to the spe_function unit. It's quite useful in complex register allocation schemes (like stenciling). - Added and improved SPE macro calculations. These are operations between registers and unsigned integer immediates. In many cases, the calculation can be performed with a single instruction; the macros will generate the single instruction if possible, or generate a register load and register-to-register operation if not. These macro functions are: spe_load_uint() (which has new ways to load a value in a single instruction), spe_and_uint(), spe_xor_uint(), spe_compare_equal_uint(), and spe_compare_greater_uint(). - Added facing to fragment generation. While rendering, the rasterizer needs to be able to determine front- and back-facing fragments, in order to correctly apply two-sided stencil. That requires these changes: - Added front_winding field to the cell_command_render block, so that the state tracker could communicate to the rasterizer what it considered to be the front-facing direction. - Added fragment facing as an input to the fragment function. - Calculated facing is passed during emit_quad(). | |||
2008-10-03 | mesa: avoid generating constant vertex attributes in fixedfunc programs | Keith Whitwell | |
Keep track of enabled/active vertex attributes. Keep track of potential vertex program outputs. When generating fragment program, replace references to fragment attributes which are effectively non-varying and non-computed passthrough attributes with references to the new CURRENT_ATTRIB tracked state value. Only downside is slight ugliness in VBO code where we need to validate state twice in succession. | |||

2008-10-01 | util: Fix util_fast_pow/exp2/log2. | José Fonseca | |
- Use a lookup table for log2. - Compute (float) (1 << ipart) by tweaking with the exponent directly to avoid integer overflow and float conversion. - Also table negative exponents to avoid float division and branching. - Implement util_fast_exp as function of util_fast_exp2. | |||
2008-09-30 | tgsi: SSE2 optimized exp2, log2 and pow implementations. | José Fonseca | |
Special care must be taken when calling compiler generated SSE2 functions from the runtime generated SSE2: saving the xmm registers, and notify gcc the stack is not 16byte aligned. It would be more efficient to keep the stack pointer 16byte aligned, but too hairy, and not consistent in all x86 architectures. This has been tested in linux x86 and windows x86 userspace. Not tested on x86-64 because it is broken for other reasons (even without this change). | |||
