* mesa/shaders: fix gl_NormalMatrix state parametersKeith Whitwell2009-07-031-1/+1
| | | | | | gl_NormalMatrix is the inverse transpose of the modelview matrix, but as every matrix here needs to be transposed, we end up with {MODELVIEW_MATRIX, INVERSE}.
* st/wgl: don't advertise WGL_EXT_swap_interval stringKeith Whitwell2009-07-031-1/+1
| | | | | | | | | | This is a tweak to a previous fix -- it's not necessary to actually advertise this extension to prevent these games from crashing -- they ignore the extension string anyway. It's sufficient to just have GetProcAddress return some dummy function addresses for SwapInterval. Given we don't really implement this funcitonality, this is a better fix.
* wgl: Lookup framebuffers by HWND whenever possible.José Fonseca2009-07-031-0/+10
| | | | | Some applications create several HDCs for the same window, so spite the WGL API is geared towards HDCs it is not reliable searching by HDC.

* Merge commit 'origin/dlist-statechange-shortcircuit' into mesa_7_5_branchKeith Whitwell2009-07-0214-37/+1011
|\ | | | | | | | | | | | | | | | | | | | | Conflicts: progs/trivial/Makefile Pull in a minimal version of statechange shortcircuiting in display list compilation. This affects only glMaterial and glShadeModel state, and includes quite a few tests to exercise various tricky cases. If this goes well, will consider extending to all state in the future.
| * mesa/vbo: fix compile and replay of nodes ending in a FALLBACKKeith Whitwell2009-06-303-13/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Where vbo save nodes are terminated with a call to DO_FALLBACK(), as in the case of a recursive CallList which is itself within a Begin/End pair, there two problems: 1) The display list node's primitive information was incorrect, stating the cut-off prim had zero vertices 2) On replay, we would get confused by a primitive that started in a node, but was terminated by individual opcodes. This change fixes the first problem by correctly terminating the last primitive on fallback, and the second by forcing the display list to use the Loopback path, converting all nodes into immediate-mode rendering. The loopback fix is a performance hit, but avoiding this would require a fairly large rework of this code.
| * mesa/dlist: fixes and improvements for material cachingKeith Whitwell2009-06-301-8/+16
| | | | | | | | | | | | | | | | | | | | | | Only short-circuit material call if *all* statechanges from this call are cached. Some material calls (eg with FRONT_AND_BACK) change more than one piece of state -- need to check all of them before returning. Also, Material calls are legal inside begin/end pairs, so don't need to be as careful about begin/end state as with regular statechanges (like ShadeModel) when caching. Take advantage of this and do better caching.
| * progs/trivial: add dlist-mat-tri.cKeith Whitwell2009-06-302-0/+183

| * progs/trivial: add test case for short-circuiting material changesKeith Whitwell2009-06-302-0/+175
| | | | | | | | | | Similar to dlist-tri-flat-tri, but using glMaterial calls, which have the extra property of being legal within Begin/End calls.
| * mesa/dlist: don't cache state which may not be replayed on CallListKeith Whitwell2009-06-301-1/+5
| | | | | | | | | | | | | | | | | | Statechanges which occur before the first End in a display list may not be replayed when the list is called, in particular if it is called from within a begin/end pair. Recognize vulnerable statechanges and do not use them to fill in the state cache.
| * progs/trivial: add dlist-flat-tri.cKeith Whitwell2009-06-302-0/+172
| | | | | | | | | | | | | | | | | | State-change functions which precede the first call to glEnd() in a compiled list are vulnerable to not being executed when that list is called. In particular this can happen if a list is invoked from within a begin/end pair, as in this example.
| * mesa/dlist: invalidate cached dlist compile state after CallListKeith Whitwell2009-06-301-16/+24
| | | | | | | | | | | | When compiling a display list containing a CallList, it is necessary to invalidate any assumption about the GL state after the recursive call completes.
| * progs/trivial: add dlist-recursive-callKeith Whitwell2009-06-302-0/+191
| | | | | | | | | | | | | | | | | | | | When one display list calls another display list, it is possible that the calling display list makes state-changes or other actions which invalidate any attempt at caching or state-change elimination in the calling list. This test exercises one such case, where the called list consists of just a single glShadeModel() call.
| * dlist-tri-flat-tri: make tri render differently if flatshade not enabledKeith Whitwell2009-06-301-1/+3
| | | | | | | | | | When testing flat-shading, it helps to specify per-vertex colors so that you can distinguish between flat & smooth shading.
| * Merge branch 'mesa_7_5_branch' into dlist-statechange-shortcircuitKeith Whitwell2009-06-3015-272/+345

| * | progs/trivial: test case for dlist statechange eliminationKeith Whitwell2009-06-302-0/+170
| | | | | | | | | | | | | | | | | | Creates a display list with redundant call to glShadeModel. View dlist contents with MESA_VERBOSE=list
| * | mesa/dlist: restore missing SAVE_FLUSH_VERTICES in save_ShadeModelKeith Whitwell2009-06-301-0/+1
| | | | | | | | | | | | | | | Reorganization of ShadeModel to avoid flushing vertices too often ended up never flushing vertices due to omitted line of code.
| * | mesa/vbo: use _lookup_prim_by_nr for debuggingKeith Whitwell2009-06-304-4/+4
| | | | | | | | | | | | Switch over to specialized enum lookup for primitives
| * | mesa: add debug printer for primitive nameKeith Whitwell2009-06-302-0/+28
| | | | | | | | | | | | | | | | | | Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive enum (GL_POINTS..GL_POLYGON). This avoids some annoying duplicates when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
| * | progs/glsl: link with GLEW libraryBrian Paul2009-06-301-1/+1

| * | mesa/dlist: shortcircuit some redundant statechanges at compile timeKeith Whitwell2009-06-302-19/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, state-changes in mesa display lists are more or less a verbatim recording of the GL calls made during compilation. This change introduces a minor optimization to recognize and eliminate cases where the application emits redundant state changes, eg: glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() The big win is when we can eliminate all the statechanges between two primitive blocks and combine them into a single VBO node. This commit implements state-change elimination for Material and ShadeModel only. This is enough to make a start on debugging, etc.

| | | | | | | | | | | | | | | | | | With recent changes to support frontfacing in glsl, it is necessary to ensure that the UsesFogFragCoord value is accurate in all shaders. We were previously not setting it for fixed-function and ARB_fs shaders.

* | | gallium: fix the front face semanticsZack Rusin2009-07-016-20/+60
| | | | | | | | | | | | | | | | | | | | | | | | mesa allocates both frontface and pointcoord registers within the fog coordinate register, by using swizzling. to make it cleaner and easier for drivers we want each of them in its own register. so when doing compilation from the mesa IR to tgsi allocate new registers for both and add new semantics to the respective declarations.

* | glx: plug a leakKristof Ralovich2009-06-301-0/+2
| | | | | | | | | | | | | | | | | | Swrast was missing a free for the culmination of driConcatConfigs. Use free(), not _mesa_free() since we shouldn't be calling any Mesa functions from the GLX code. driConcatConfigs() should probably use regular malloc/free to be consistant but the Mesa functions just wrap the libc functions anyway.

* | gallium: New PIPE_BUFFER_USAGE_FLUSH_EXPLICIT flag for ↵José Fonseca2009-06-303-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | buffer_flush_mapped_range. When a buffer was mapped for write and no explicit flush range was provided the existing semantics were that the whole buffer would be flushed, mostly for backwards compatability with non map-buffer-range aware code. However if the buffer was mapped/unmapped with nothing really written -- something that often happens with the vbo -- we were unnecessarily assuming that the whole buffer was written. The new PIPE_BUFFER_USAGE_FLUSH_EXPLICIT flag (based from ARB_map_buffer_range 's GL_MAP_FLUSH_EXPLICIT_BIT flag) allows to clearly distinguish the legacy usage from the nothing written usage.
