* i965/fs: New peephole optimization to generate SEL.Matt Turner2013-12-044-0/+225
| | | | | | | | | | | | | | | | | | | | | fs_visitor::try_replace_with_sel optimizes only if statements whose "then" and "else" bodies contain a single MOV instruction. It also could not handle constant arguments, since they cause an extra MOV immediate to be generated (since we haven't run constant propagation, there are more than the single MOV). This peephole fixes both of these and operates as a normal optimization pass. fs_visitor::try_replace_with_sel is still arguably necessary, since it runs before pull constant loads are lowered. total instructions in shared programs: 1559129 -> 1545833 (-0.85%) instructions in affected programs: 167120 -> 153824 (-7.96%) GAINED: 13 LOST: 6 Reviewed-by: Paul Berry <[email protected]>

* i965/cfg: Rework to make IF & ELSE blocks flow into ENDIF.Matt Turner2013-12-042-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we made the basic block following an ENDIF instruction a successor of the basic blocks ending with IF and ELSE. The PRM says that IF and ELSE instructions jump *to* the ENDIF, rather than over it. This should be immaterial to dataflow analysis, except for if, break, endif sequences: START B1 <-B0 <-B9 0x00000100: cmp.g.f0(8) null g15<8,8,1>F g4<0,1,0>F 0x00000110: (+f0) if(8) 0 0 null 0x00000000UD END B1 ->B2 ->B4 START B2 <-B1 break 0x00000120: break(8) 0 0 null 0D END B2 ->B10 START B3 0x00000130: endif(8) 2 null 0x00000002UD END B3 ->B4 The ENDIF block would have no parents, so dataflow analysis would generate incorrect results, preventing copy propagation from eliminating some instructions. This patch changes the CFG to make ENDIF start rather than end basic blocks, so that it can be the jump target of the IF and ELSE instructions. It helps three programs (including two fs8/fs16 pairs). total instructions in shared programs: 1561126 -> 1561060 (-0.00%) instructions in affected programs: 837 -> 771 (-7.89%) More importantly, it allows copy propagation to handle more cases. Disabling the register_coalesce() pass before this patch hurts 58 programs, while afterward it only hurts 11 programs. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | | | This extension enabled the use of texture array with fixed-function and assembly fragment shaders. No applications are known to use this extension. NOTE: This patch regresses GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY cases of the copyteximage piglit test. The test is incorrectly using texture arrays with fixed function while only requiring the GL_EXT_texture_array extension.

* wayland: Add an extension to create wl_buffers from EGLImagesNeil Roberts2013-12-045-0/+113
| | | | | | | | | | | | | | | | | | This adds an extension called EGL_WL_create_wayland_buffer_from_image which adds the following single function: struct wl_buffer * eglCreateWaylandBufferFromImageWL(EGLDisplay dpy, EGLImageKHR image); The function creates a wl_buffer which shares its contents with the given EGLImage. The expected use case for this is in a nested Wayland compositor which is using subsurfaces to present buffers from its clients. Using this extension it can attach the client buffers directly to the subsurface without having to blit the contents into an intermediate buffer. The compositing can then be done in the parent compositor. The extension is only implemented in the Wayland EGL platform because of course it wouldn't make sense anywhere else.
* egl/wayland: Damage INT32_MAX x INT32_MAX region for eglSwapBuffersKristian Høgsberg2013-12-041-2/+2
| | | | | | | | | | | | | | | | If we're not using EGL_EXT_swap_buffers_with_damage, we have to damage the full extent. EGL operates on buffer coordinates, but wl_surface.damage takes surface coordinates. EGL doesn't know the buffer transformation (rotated or scaled) and can't post accurate damage in surface coordinates. The damage event however is clipped to the surface extents so we can just damage the maximum rectangle. In case of EGL_EXT_swap_buffers_with_damage, the application knows the buffer transform and is expected to pass in rectangles in surface space. https://bugs.freedesktop.org/show_bug.cgi?id=70250 Cc: "10.0" [email protected]

* egl/wayland: Send commit after flushing the driver contextKristian Høgsberg2013-12-041-2/+1
| | | | | | | | | | This typically won't make a difference, since we only send the requests at wl_display_flush() time. There might be a small race with another thread calling wl_display_flush() after our commit request, but before we flush the DRI driver. Moving the commit below the DRI driver flush call looks more natural and eliminates the small race. Cc: "10.0" [email protected]
* egl/wayland: Flush the wl_display at the end of SwapBuffersAxel Davy2013-12-041-0/+2
| | | | | | | | | | We would like the compositor to receive the commited buffer as soon as possible, so it has the time to treat it, and release old ones. We shouldn't rely on the client to flush the queue for us. Signed-off-by: Axel Davy <[email protected]> Cc: "10.0" [email protected]
* mesa: reduce memory used for short display listsBrian Paul2013-12-041-0/+35
| | | | | | | | | | | | | Display lists allocate memory in chunks of 256 tokens (1KB) at a time. If an app creates many short display lists or uses glXUseXFont() this can waste quite a bit of memory.

* mesa: begin reducing memory used by display listsBrian Paul2013-12-041-172/+252
| | | | | | | | | | | | | | | | | This is a first step in reducing memory used by display lists on 64-bit systems. On 64-bit systems, the gl_dlist_node union type is 8 bytes because of the 'data' and 'next' fields. This causes every display list node/token to occupy 8 bytes instead of 4 as originally designed. This basically doubles the memory used by some display lists on 64-bit systems. The fix is to remove the 64-bit 'data' and 'next' pointer fields from the union and instead store them as a pair of 32-bit values. Easily done with a few helper functions. The next patch will take care of the 'next' field. Reviewed-by: Ian Romanick <[email protected]>
