* wayland: Don't rely on static variable for identifying wl_drm buffersKristian Høgsberg2013-10-116-15/+35
| | | | | | | | | | | | Now that libEGL has been fixed to not leak all kinds of symbols, gbm links to its own copy of the libwayland-drm.a helper library. That means we can't rely on comparing the addresses of a static vtable symbol in that library to determine if a wl_buffer is a wl_drm_buffer. Instead, we move the vtable into the wl_drm struct and use that for comparing. https://bugs.freedesktop.org/show_bug.cgi?id=69437 Cc: 9.2 <[email protected]>

* mesa: Allow external textures to use fallback (0, 0, 0, 1)Topi Pohjolainen2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes GL2ExtensionTests/egl_image_external/TestSimpleUnassociated.test which is part of gles2/3 conformance suite. Here image external textures are switched to be treated the same as 2D textures. These can be associated with the fallback texture providing fixed sample values of (0, 0, 0, 1). The OES_EGL_image_external spec says: "Sampling an external texture which is not associated with any EGLImage sibling will return a sample value of (0,0,0,1)." "External textures cannot be used with TexImage2D, TexSubImage2D, CompressedTexImage2D, CompressedTexSubImage2D, CopyTexImage2D, or CopyTexSubImage2D, and an INVALID_ENUM error will be generated if this is attempted." And quoting Chad: "That's enforced in _mesa_TexImage*() by calling legal_teximage_target(), and enforced in _mesa_TexSubImage*() by calling legal_texsubmimage_target(). Each of the legal_tex*image_target() functions reject external textures. Therefore, allowing GL_TEXTURE_EXTERNAL_OES in store_texsubimage() won't violate the above spec quote. I think it's safe to allow GL_TEXTURE_EXTERNAL_OES in store_texsubimage(), as long as the texture has only a single plane. Luckily, that's the only type of external textures that Mesa currently supports."

| | | | | | | | | | | | | | | The intel_screen.c used to be a dispatch to one of 3 driver functions, but was down to 1, so it was kind of a waste. In addition, it was trying to free all of the data that might have been partially freed in the kernel 3.6 check (which comes after intelInitContext, and thus might have had driverPrivate set and result in intelDestroyContext() doing work on the freed data).

* i965/fs: Convert gen7 to using GRFs for texture messages.Eric Anholt2013-10-109-109/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looking at Lightsmark's shaders, the way we used MRFs (or in gen7's case, GRFs) was bad in a couple of ways. One was that it prevented compute-to-MRF for the common case of a texcoord that gets used exactly once, but where the texcoord setup all gets emitted before the texture calls (such as when it's a bare fragment shader input, which gets interpolated before processing main()). Another was that it introduced a bunch of dependencies that constrained scheduling, and forced waits for texture operations to be done before they are required. For example, we can now move the compute-to-MRF interpolation for the second texture send down after the first send. The downside is that this generally prevents remove_duplicate_mrf_writes() from doing anything, whereas previously it avoided work for the case of sampling from the same texcoord twice. However, I suspect that most of the win that originally justified that code was in avoiding the WAR stall on the first send, which this patch also avoids, rather than the small cost of the extra instruction. We see instruction count regressions in shaders in unigine, yofrankie, savage2, hon, and gstreamer. Improves GLB2.7 performance by 0.633628% +/- 0.491809% (n=121/125, avg of ~66fps, outliers below 61 dropped). Improves openarena performance by 1.01092% +/- 0.66897% (n=425). No significant difference on Lightsmark (n=44). v2: Squash in the fix for register unspilling for send-from-GRF, fixing a segfault in lightsmark.

* i965/fs: Do live variables dataflow analysis on a per-channel level.Eric Anholt2013-10-102-17/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This significantly improves our handling of VGRFs of size > 1. Previously, we only marked VGRFs as def'd if the whole register was written by a single instruction. Large VGRFs which were written piecemeal would not be considered def'd at all, even if they were ultimately completely written. Without being def'd, these were then marked "live in" to the basic block, often extending the range to preceding blocks and sometimes even the start of the program. The new per-component tracking gives more accurate live intervals, which makes register coalescing more effective. In the future, this should help with texturing from GRFs on Gen7+. A sampler message might be represented by a 2-register VGRF which holds the texture coordinates. If those are incoming varyings, they'll be produced by two PLN instructions, which are piecemeal writes. No reduction in shader-db instruction counts. However, code which prints the live interval ranges does show that some VGRFs now have smaller (and more correct) live intervals. v2: Rebase on current send-from-GRF code requiring adding extra use[]s. v3: Rebase on live intervals fix to include defs in the end of the interval. v4 (Kenneth Graunke): Rebase; split off a few preparatory patches; add lots of comments; minor style changes; rewrite commit message. v5 (Eric Anholt): whitespace nit.

* glsl: Catch redeclaration of interface block instance names at compile time.Paul Berry2013-10-101-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From section 4.1.9 (Arrays) of the GLSL 4.40 spec (as of revision 7): However, unless noted otherwise, blocks cannot be redeclared; an unsized array in a user-declared block cannot be sized through redeclaration. The only place where the spec notes that interface blocks can be redeclared is to allow for redeclaration of built-in interface blocks such as gl_PerVertex. Therefore, user-defined interface blocks can never be redeclared. This is a clarification of previous intent (see Khronos bug 10659). We were already preventing interface block redeclaration using the same block name at compile time, but we weren't preventing interface block redeclaration using the same instance name (and different block names) at compile time. And we weren't preventing an instance name from conflicting with a previously-declared ordinary variable. In practice the problem would be caught at link time, but only because of a coincidence: since ast_interface_block::hir() wasn't doing any checking to see if the instance name already existed in the shader, it was creating a second ir_variable in the shader having the same name but a different type. Coincidentally, when the linker checked for intrastage consistency of global variable declarations, it treated the two declarations from the same shader as a conflict, so it reported a link error. But it seems dangerous to rely on that linker behaviour to catch illegal redeclarations that really ought to be detected at compile time. Reviewed-by: Ian Romanick <[email protected]>
