From: Roland Scheidegger Date: Wed, 11 Jul 2007 12:20:39 +0000 (+0200) Subject: some fixes, fake frontbuffer X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=43e24ff50773575d28763d899a4f25bb430418b5;p=mesa.git some fixes, fake frontbuffer still doesn't work quite right (resize). Fake frontbuffer doesn't copy in real frontbuffer. Don't even think about doing rotation/page flip/triple buffering for now... More cleanups needed (fake cliprects etc.) --- diff --git a/src/mesa/drivers/dri/i915tex/i915_vtbl.c b/src/mesa/drivers/dri/i915tex/i915_vtbl.c index f80e8d6327f..51aff688402 100644 --- a/src/mesa/drivers/dri/i915tex/i915_vtbl.c +++ b/src/mesa/drivers/dri/i915tex/i915_vtbl.c @@ -463,6 +463,7 @@ i915_state_draw_region(struct intel_context *intel, * Set stride/cpp values */ if (color_region) { +// fprintf(stderr, "color pitch %d\n", color_region->pitch); state->Buffer[I915_DESTREG_CBUFADDR0] = _3DSTATE_BUF_INFO_CMD; state->Buffer[I915_DESTREG_CBUFADDR1] = (BUF_3D_ID_COLOR_BACK | @@ -471,6 +472,7 @@ i915_state_draw_region(struct intel_context *intel, } if (depth_region) { +// fprintf(stderr, "depth pitch %d\n", depth_region->pitch); state->Buffer[I915_DESTREG_DBUFADDR0] = _3DSTATE_BUF_INFO_CMD; state->Buffer[I915_DESTREG_DBUFADDR1] = (BUF_3D_ID_DEPTH | diff --git a/src/mesa/drivers/dri/i915tex/intel_blit.c b/src/mesa/drivers/dri/i915tex/intel_blit.c index b4fc1691e6b..d6651f62be1 100644 --- a/src/mesa/drivers/dri/i915tex/intel_blit.c +++ b/src/mesa/drivers/dri/i915tex/intel_blit.c @@ -82,9 +82,11 @@ intelCopyBuffer(const __DRIdrawablePrivate * dPriv, if (dPriv && dPriv->numClipRects) { struct intel_framebuffer *intel_fb = dPriv->driverPrivate; const struct intel_region *frontRegion - = intel_get_rb_region(&intel_fb->Base, BUFFER_FRONT_LEFT); + = intelScreen->front_region; const struct intel_region *backRegion - = intel_get_rb_region(&intel_fb->Base, BUFFER_BACK_LEFT); + = intel->ctx.DrawBuffer->_ColorDrawBufferMask[0] == BUFFER_BIT_FRONT_LEFT ? + intel_get_rb_region(&intel_fb->Base, BUFFER_FRONT_LEFT) : + intel_get_rb_region(&intel_fb->Base, BUFFER_BACK_LEFT); const int nbox = dPriv->numClipRects; const drm_clip_rect_t *pbox = dPriv->pClipRects; const int pitch = frontRegion->pitch; @@ -100,7 +102,7 @@ intelCopyBuffer(const __DRIdrawablePrivate * dPriv, // ASSERT(frontRegion->pitch == backRegion->pitch); ASSERT(frontRegion->cpp == backRegion->cpp); - DBG("copy buffer, front pitch %d back pitch %d\n", + DBG("front pitch %d back pitch %d\n", frontRegion->pitch, backRegion->pitch); if (cpp == 2) { @@ -138,6 +140,11 @@ intelCopyBuffer(const __DRIdrawablePrivate * dPriv, continue; } + DBG("box x1 x2 y1 y2 %d %d %d %d\n", + box.x1, box.x2, box.y1, box.y2); + + /* XXX should make sure only the minimum area based on + old draw buffer and new front clip rects is copied */ sbox.x1 = box.x1 - dPriv->x; sbox.y1 = box.y1 - dPriv->y; @@ -417,9 +424,8 @@ intelClearWithBlit(GLcontext * ctx, GLbitfield mask) b = *box; } - if (0) - _mesa_printf("clear %d,%d..%d,%d, mask %x\n", - b.x1, b.y1, b.x2, b.y2, mask); + DBG("clear %d,%d..%d,%d, mask %x\n", + b.x1, b.y1, b.x2, b.y2, mask); /* Loop over all renderbuffers */ for (buf = 0; buf < BUFFER_COUNT && clearMask; buf++) { diff --git a/src/mesa/drivers/dri/i915tex/intel_buffers.c b/src/mesa/drivers/dri/i915tex/intel_buffers.c index e8dd7cd5240..fbaa4ee4f31 100644 --- a/src/mesa/drivers/dri/i915tex/intel_buffers.c +++ b/src/mesa/drivers/dri/i915tex/intel_buffers.c @@ -930,7 +930,7 @@ intelSwapBuffers(__DRIdrawablePrivate * dPriv) GLboolean missed_target; struct intel_framebuffer *intel_fb = dPriv->driverPrivate; int64_t ust; - + _mesa_notifySwapBuffers(ctx); /* flush pending rendering comands */ if (screen->current_rotation != 0 || @@ -956,6 +956,16 @@ intelSwapBuffers(__DRIdrawablePrivate * dPriv) intel_fb->swap_ust = ust; } + if (dPriv && intel->lastStamp != dPriv->lastStamp) { + /* XXX this doesn't appear to work quite right. + And in any case, it will never get called with single buffered + rendering here... + And if it's only a window move (not resize), don't need to do anything. */ + if (INTEL_DEBUG & DEBUG_LOCK) + _mesa_printf("doing defered drawable update\n"); + intelWindowMoved(intel); + intel->lastStamp = dPriv->lastStamp; + } } else { /* XXX this shouldn't be an error but we can't handle it for now */ @@ -1068,21 +1078,12 @@ intel_draw_buffer(GLcontext * ctx, struct gl_framebuffer *fb) * And set up cliprects. */ if (fb->Name == 0) { + intelSetPrivbufClipRects(intel); /* drawing to window system buffer */ if (front) { -#if 0 - intelSetFrontClipRects(intel); -#else - intelSetPrivbufClipRects(intel); -#endif colorRegion = intel_get_rb_region(fb, BUFFER_FRONT_LEFT); } else { -#if 0 - intelSetBackClipRects(intel); -#else - intelSetPrivbufClipRects(intel); -#endif colorRegion = intel_get_rb_region(fb, BUFFER_BACK_LEFT); } } diff --git a/src/mesa/drivers/dri/i915tex/intel_context.c b/src/mesa/drivers/dri/i915tex/intel_context.c index 028e57e5ab6..76426e3c882 100644 --- a/src/mesa/drivers/dri/i915tex/intel_context.c +++ b/src/mesa/drivers/dri/i915tex/intel_context.c @@ -282,18 +282,22 @@ intelFlush(GLcontext * ctx) * Check if we need to rotate/warp the front color buffer to the * rotated screen.
