From f0eb02af800ea1c4be6847ead0096d368d9276ff Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Thu, 26 Aug 2010 06:44:02 +0100 Subject: graw: Dynamically load graw libraries. This allows to build multiple graws libs simultaneously and avoid unnecessary rebuilds of the tests. Also remove graw_util.c from inside the graw implementation -- it was only being provided by one implementation, and graw tests were linking against gallium anyway. --- src/gallium/targets/graw-xlib/graw_util.c | 49 ------------------------------- 1 file changed, 49 deletions(-) delete mode 100644 src/gallium/targets/graw-xlib/graw_util.c (limited to 'src/gallium/targets/graw-xlib/graw_util.c') diff --git a/src/gallium/targets/graw-xlib/graw_util.c b/src/gallium/targets/graw-xlib/graw_util.c deleted file mode 100644 index 47aca4464db..00000000000 --- a/src/gallium/targets/graw-xlib/graw_util.c +++ /dev/null @@ -1,49 +0,0 @@ - -#include "pipe/p_compiler.h" -#include "pipe/p_context.h" -#include "tgsi/tgsi_text.h" -#include "util/u_memory.h" -#include "state_tracker/graw.h" - - -/* Helper functions.

Keith prefers a clean separation between graw applications and implementations, where apps do not link libgallium.a but instead get all functionality they need via graw interface. Although this is not incompatible with late loading of graw drivers, it it would make it very hard to maintain, as wrappers for every utility symbol exposed in graw would have to be written or generated somehow. --- SConstruct | 3 +- src/gallium/include/state_tracker/graw_dl.h | 153 ---------------------------- src/gallium/targets/SConscript | 5 + src/gallium/targets/graw-null/SConscript | 58 +++++++++++ src/gallium/targets/graw-null/graw_null.c | 95 +++++++++++++++++ src/gallium/targets/graw-xlib/SConscript | 1 + src/gallium/targets/graw-xlib/graw_util.c | 50 +++++++++ src/gallium/tests/graw/SConscript | 9 +- src/gallium/tests/graw/clear.c | 2 +- src/gallium/tests/graw/fs-test.c | 2 +- src/gallium/tests/graw/gs-test.c | 2 +- src/gallium/tests/graw/quad-tex.c | 2 +- src/gallium/tests/graw/tri-gs.c | 2 +- src/gallium/tests/graw/tri-instanced.c | 2 +- src/gallium/tests/graw/tri.c | 2 +- src/gallium/tests/graw/vs-test.c | 2 +- 16 files changed, 227 insertions(+), 163 deletions(-) delete mode 100644 src/gallium/include/state_tracker/graw_dl.h create mode 100644 src/gallium/targets/graw-null/SConscript create mode 100644 src/gallium/targets/graw-null/graw_null.c create mode 100644 src/gallium/targets/graw-xlib/graw_util.c (limited to 'src/gallium/targets/graw-xlib/graw_util.c') diff --git a/SConstruct b/SConstruct index 14663727f52..bb03e5055ea 100644 --- a/SConstruct +++ b/SConstruct @@ -31,7 +31,7 @@ import common # Configuration options default_statetrackers = 'mesa' -default_targets = 'none' +default_targets = 'graw-null' if common.default_platform in ('linux', 'freebsd', 'darwin'): default_drivers = 'softpipe,failover,svga,i915,i965,trace,identity,llvmpipe' @@ -69,6 +69,7 @@ opts.Add(ListVariable('targets', 'driver targets to build', default_targets, 'egl-swrast', 'egl-vmwgfx', 'graw-xlib', + 'graw-null', 'libgl-gdi', 'libgl-xlib', 'xorg-i915', diff --git a/src/gallium/include/state_tracker/graw_dl.h b/src/gallium/include/state_tracker/graw_dl.h deleted file mode 100644 index 3c5c3d86473..00000000000 --- a/src/gallium/include/state_tracker/graw_dl.h +++ /dev/null @@ -1,153 +0,0 @@ -#ifndef GALLIUM_RAW_DL_H -#define GALLIUM_RAW_DL_H - -/* This is an API for exercising gallium functionality in a - * platform-neutral fashion.
