Alexandre Julliard : opengl32: Don't use ENTER_GL/ LEAVE_GL around calls to driver functions.
Module: wine Branch: master Commit: 6e01e4aa519e99ea1981b97f925e0d7a7bf7c90a URL: http://source.winehq.org/git/wine.git/?a=commit;h=6e01e4aa519e99ea1981b97f92... Author: Alexandre Julliard <julliard(a)winehq.org> Date: Tue Dec 12 18:21:01 2006 +0100 opengl32: Don't use ENTER_GL/LEAVE_GL around calls to driver functions. This causes lock inversions when the driver accesses the DC. --- dlls/opengl32/wgl.c | 18 +---------- dlls/winex11.drv/opengl.c | 72 ++++++++++++++++++++++++++++---------------- 2 files changed, 47 insertions(+), 43 deletions(-) diff --git a/dlls/opengl32/wgl.c b/dlls/opengl32/wgl.c index 792707e..344af98 100644 --- a/dlls/opengl32/wgl.c +++ b/dlls/opengl32/wgl.c @@ -569,9 +569,7 @@ BOOL WINAPI wglUseFontOutlinesW(HDC hdc, void WINAPI wine_glEnable( GLenum cap ) { TRACE("(%d)\n", cap ); - ENTER_GL(); wine_wgl.p_wglEnable(cap); - LEAVE_GL(); } /*********************************************************************** @@ -579,12 +577,8 @@ void WINAPI wine_glEnable( GLenum cap ) */ GLboolean WINAPI wine_glIsEnabled( GLenum cap ) { - GLboolean ret_value; TRACE("(%d)\n", cap ); - ENTER_GL(); - ret_value = wine_wgl.p_wglIsEnabled(cap); - LEAVE_GL(); - return ret_value; + return wine_wgl.p_wglIsEnabled(cap); } /*********************************************************************** @@ -593,9 +587,7 @@ GLboolean WINAPI wine_glIsEnabled( GLenu void WINAPI wine_glDisable( GLenum cap ) { TRACE("(%d)\n", cap ); - ENTER_GL(); wine_wgl.p_wglDisable(cap); - LEAVE_GL(); } /*********************************************************************** @@ -604,9 +596,7 @@ void WINAPI wine_glDisable( GLenum cap ) void WINAPI wine_glScissor( GLint x, GLint y, GLsizei width, GLsizei height ) { TRACE("(%d, %d, %d, %d)\n", x, y, width, height ); - ENTER_GL(); wine_wgl.p_wglScissor(x, y, width, height); - LEAVE_GL(); } /*********************************************************************** @@ -615,9 +605,7 @@ void WINAPI wine_glScissor( GLint x, GLi void WINAPI wine_glViewport( GLint x, GLint y, GLsizei width, GLsizei height ) { TRACE("(%d, %d, %d, %d)\n", x, y, width, height ); - ENTER_GL(); wine_wgl.p_wglViewport(x, y, width, height); - LEAVE_GL(); } /*********************************************************************** @@ -678,11 +666,7 @@ const GLubyte * WINAPI wine_glGetString( */ void WINAPI wine_glGetIntegerv( GLenum pname, GLint* params ) { - ENTER_GL(); - glGetIntegerv(pname, params); - /* A few parameters like GL_DEPTH_BITS differ between WGL and GLX, the wglGetIntegerv helper function handles those */ wine_wgl.p_wglGetIntegerv(pname, params); - LEAVE_GL(); } diff --git a/dlls/winex11.drv/opengl.c b/dlls/winex11.drv/opengl.c index 927abfc..2769580 100644 --- a/dlls/winex11.drv/opengl.c +++ b/dlls/winex11.drv/opengl.c @@ -1463,6 +1463,8 @@ static void sync_current_drawable(void) width = ctx->physDev->dc_rect.right - ctx->physDev->dc_rect.left; height = ctx->physDev->dc_rect.bottom - ctx->physDev->dc_rect.top; + wine_tsx11_lock(); + pglViewport(ctx->physDev->dc_rect.left + ctx->viewport.left, dy + ctx->viewport.top, ctx->viewport.right ?
