From: Roland Scheidegger Date: Fri, 28 May 2010 23:28:21 +0000 (+0200) Subject: i915g: adapt to clear interface changes X-Git-Tag: 062012170305~12030^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4bc7b14224bfb9c5efe37e1505345fb90ba69d9e;p=profile%2Fivi%2Fmesa.git i915g: adapt to clear interface changes should in theory support separate depth/stencil clears (untested). Also fix some format omissions? --- diff --git a/src/gallium/drivers/i915/i915_blit.c b/src/gallium/drivers/i915/i915_blit.c index 6717e46..c5b5979 100644 --- a/src/gallium/drivers/i915/i915_blit.c +++ b/src/gallium/drivers/i915/i915_blit.c @@ -36,6 +36,7 @@ void i915_fill_blit(struct i915_context *i915, unsigned cpp, + unsigned rgba_mask, unsigned short dst_pitch, struct i915_winsys_buffer *dst_buffer, unsigned dst_offset, @@ -62,8 +63,7 @@ i915_fill_blit(struct i915_context *i915, case 4: BR13 = (((int) dst_pitch) & 0xffff) | (0xF0 << 16) | (1 << 24) | (1 << 25); - CMD = (XY_COLOR_BLT_CMD | XY_COLOR_BLT_WRITE_ALPHA | - XY_COLOR_BLT_WRITE_RGB); + CMD = (XY_COLOR_BLT_CMD | rgba_mask); break; default: return; diff --git a/src/gallium/drivers/i915/i915_blit.h b/src/gallium/drivers/i915/i915_blit.h index 43f8e7c..d82d2f2 100644 --- a/src/gallium/drivers/i915/i915_blit.h +++ b/src/gallium/drivers/i915/i915_blit.h @@ -44,6 +44,7 @@ extern void i915_copy_blit(struct i915_context *i915, extern void i915_fill_blit(struct i915_context *i915, unsigned cpp, + unsigned rgba_mask, unsigned short dst_pitch, struct i915_winsys_buffer *dst_buffer, unsigned dst_offset, diff --git a/src/gallium/drivers/i915/i915_clear.c b/src/gallium/drivers/i915/i915_clear.c index 0d0859f..6d824a5 100644 --- a/src/gallium/drivers/i915/i915_clear.c +++ b/src/gallium/drivers/i915/i915_clear.c @@ -40,7 +40,7 @@ */ void i915_clear(struct pipe_context *pipe, unsigned buffers, const float *rgba, - double depth, unsigned stencil) + double depth, unsigned stencil) { util_clear(pipe, &i915_context(pipe)->framebuffer, buffers, rgba, depth, stencil); diff --git a/src/gallium/drivers/i915/i915_screen.c b/src/gallium/drivers/i915/i915_screen.c index 0897a86..3e2d082 100644 --- a/src/gallium/drivers/i915/i915_screen.c +++ b/src/gallium/drivers/i915/i915_screen.c @@ -129,6 +129,9 @@ i915_get_param(struct pipe_screen *screen, enum pipe_cap param) case PIPE_CAP_TGSI_FS_COORD_ORIGIN_LOWER_LEFT: case PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_INTEGER: return 0; + case PIPE_CAP_DEPTHSTENCIL_CLEAR_SEPARATE: + /* disable for now */ + return 0; default: return 0; } @@ -181,6 +184,9 @@ i915_is_format_supported(struct pipe_screen *screen, PIPE_FORMAT_L8A8_UNORM, PIPE_FORMAT_UYVY, PIPE_FORMAT_YUYV, + /* XXX why not?
