* i965: Delete gen7_upload_sampler_state_table and vtable mechanism.Kenneth Graunke2014-08-025-70/+3
| | | | | | | | | | | brw_upload_sampler_state_table now handles all generations, so we don't need the vtable mechanism either. There's still a lot of code duplication; the next patches will address that. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Topi Pohjolainen <[email protected]>
* i965: Make brw_upload_sampler_state_table handle Gen7+ as well.Kenneth Graunke2014-08-023-5/+49
| | | | | | | | | | | | | | | | This copies a few changes from gen7_upload_sampler_state_table; the next patch will delete that function. Gen7+ has per-stage sampler state pointer update packets, so we emit them as soon as we emit a new table for a stage. On Gen6 and earlier, we have a single packet, so we delay until we've changed everything that's going to be changed. v2: Split 3DSTATE_SAMPLER_STATE_POINTERS_XS packet emission into a helper function (suggested by Topi Pohjolainen).

* i965: Shift brw_upload_sampler_state_table away from structures.Kenneth Graunke2014-08-021-8/+15
| | | | | | | | | | | | The Gen4-6 and Gen7+ code is virtually identical, but both use different structure types. Switching to use a uint32_t pointer and operate on the number of DWords will make it possible to share code. It turns out that SURFACE_STATE is the same number of DWords on every platform currently; it will be easy to handle a change there, though.

| | | | | | | | | | | | Other than this, brw_update_sampler_state only deals with a single SAMPLER_STATE structure, and doesn't need to know which position it is in the table. The caller takes care of dealing with multiple surface states. Pushing this up a level allows us to drop the ss_index parameter.

| | | | | | | | | | | | | | | When the driver was originally written, it only supported texturing in the pixel shader backend; vertex and geometry shader texturing came much later. Originally, the pixel shader was referred to as "WM" (the Windowizer/Masker unit). So, this code happened to only be relevant for the WM stage, at the time. However, sampler state really applies to all stages, so putting "wm" in the filename doesn't make sense. I dropped it in gen7_sampler_state.c; at this point the asymmetry just trips people up.

| | | | | | | | | | | | | | | | This could be recalculated, though it turns out the only use of it after resource allocation is for calculating whole resource size (for scene size accounting though that isn't quite ideal neither).

| | | | | | | | | | | | | | | | | | | When using (d3d10) conformant out-of-bound behavior for texel fetching (currently always enabled) the level still needs to be set to a safe value even though the offset in the end won't get used because the level is used to look up the mip offset itself and the actual strides, which might otherwise crash. For simplicity, we'll use level 0 in this case (this ought to be safe, llvmpipe does not actually fill in level 0 information if first_level is larger, but some random strides / offsets shouldn't hurt as ultimately we always use offset 0 in this case). Fixes a crash in some in-house test where random huge levels appear in lp_build_fetch_texel() (the test actually uses level 0 always but if the fetching happens in a block with a execution mask random values may appear).

* dri: Add a new capabilities for drivers that can't share buffersGiovanni Campagna2014-07-307-12/+69
| | | | | | | | | | | | | | | | | | | The kms-dri swrast driver cannot share buffers using the GEM, so it must tell the loader to disable extensions relying on that, without disabling the image DRI extension altogether (which would prevent the loader from working at all). This requires a new gallium capability (which is queried on the pipe_screen and for swrast drivers it's forwarded to the winsys), and requires a new version of the DRI image extension.

Ages ago, Mesa's build system only added -g in dri-debug builds (yay for the static Makefiles).

| | | | | | | | | | | | | | | | | | | | | | | | We've had multiple bugs in the past where we have been inadvertently matching the default rule, (which we never want to do). We recently added a catch-all rule to avoid this, (and made this rule robust for future start conditions). Kristian pointed out that flex allows us to go one step better. This syntax: %option warn nodefault instructs flex to not generate the default rule at all. Further, flex will generate a warning at compile time if the set of rules we provide are inadequate, (such that it would be possible for the default rule to be matched). With this warning in place, I found that the catch-all rule was in fact missing something. The catch-all rule uses a pattern of "." which doesn't match newlines.

| | | | | | | | | | | | | | | | | | In some of the recent glcpp bug-fixing, we found that glcpp was emitting unrecognized characters from the input source file to stdout, and dropping them from the source passed onto the compiler proper. This was obviously confusing, and totally undesired. The bogus behavior comes from an implicit default rule in flex, which is that any unmatched character is implicitly matched and printed to stdout. To avoid this implicit matching and printing, here we add an explicit catch-all rule. If this rule ever matches it prints an internal compiler error. The correct response for any such error is fixing glcpp to handle the unexpected character in the correct way. Reviewed-by: Jordan Justen <[email protected]>

| | | | | | | | | | | | | | | | | | | Previously, the '\r' character was not explicitly matched by any lexer rule. This means that glcpp would have been using the default flex rule to match '\r' characters, (where they would have been printed to stdout rather than actually correctly handled). With this commit, we treat '\r' as equivalent to '\n'. This is clearly an improvement the bogus printing to stdout. The resulting behavior is compliant with the GLSL specification for any source file that uses exclusively '\r' or '\n' to separate lines. For shaders that use a multiple-character line separator, (such as "\r\n"), glcpp won't be precisely compliant with the specification, (treating these as two newline characters rather than one), but this should not introduce any semantic changes to the shader programs.

For the curious: The bug happened when the NEWLINE_CATCHUP code didn't actually return the NEWLINE token (due to the skipping). This resulted in the lexer continuing on through all the subsequent rules while still in the NEWLINE_CATCHUP start condition, (which then triggered the internal-compiler-error catch-all rule).
