From: Chia-I Wu Date: Sun, 21 Feb 2010 02:58:22 +0000 (+0800) Subject: st/egl: Add event support to the native display interface. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e38f28ddedd6d4902ae18b1bf243e67d4b16decb;p=mesa.git st/egl: Add event support to the native display interface. There is only invalid_surface event right now. When EGL receives the event, it sets the force_validate flag of the context binding to the surface. This helps skip an unnecessary check. --- diff --git a/src/gallium/state_trackers/egl/common/egl_g3d.c b/src/gallium/state_trackers/egl/common/egl_g3d.c index 04268c71c5a..ddb1ef1bf1f 100644 --- a/src/gallium/state_trackers/egl/common/egl_g3d.c +++ b/src/gallium/state_trackers/egl/common/egl_g3d.c @@ -531,6 +531,24 @@ egl_g3d_update_buffer(struct pipe_screen *screen, void *context_private) egl_g3d_validate_context(gctx->base.Resource.Display, &gctx->base); } +static void +egl_g3d_invalid_surface(struct native_display *ndpy, + struct native_surface *nsurf, + unsigned int seq_num) +{ + /* XXX not thread safe? */ + struct egl_g3d_surface *gsurf = egl_g3d_surface(nsurf->user_data); + struct egl_g3d_context *gctx = egl_g3d_context(gsurf->base.CurrentContext); + + /* set force_validate to skip an unnecessary check */ + if (gctx) + gctx->force_validate = TRUE; +} + +static struct native_event_handler egl_g3d_native_event_handler = { + .invalid_surface = egl_g3d_invalid_surface +}; + static EGLBoolean egl_g3d_terminate(_EGLDriver *drv, _EGLDisplay *dpy) { @@ -575,12 +593,14 @@ egl_g3d_initialize(_EGLDriver *drv, _EGLDisplay *dpy, } dpy->DriverData = gdpy; - gdpy->native = native_create_display(dpy->NativeDisplay); + gdpy->native = native_create_display(dpy->NativeDisplay, + &egl_g3d_native_event_handler); if (!gdpy->native) { _eglError(EGL_NOT_INITIALIZED, "eglInitialize(no usable display)"); goto fail; } + gdpy->native->user_data = (void *) dpy; gdpy->native->screen->flush_frontbuffer = egl_g3d_flush_frontbuffer; gdpy->native->screen->update_buffer = egl_g3d_update_buffer; @@ -776,6 +796,7 @@ egl_g3d_create_surface(_EGLDriver *drv, _EGLDisplay *dpy, _EGLConfig *conf, return NULL; } + nsurf->user_data = &gsurf->base; gsurf->native = nsurf; gsurf->render_att = (gsurf->base.RenderBuffer == EGL_SINGLE_BUFFER) ? diff --git a/src/gallium/state_trackers/egl/common/native.h b/src/gallium/state_trackers/egl/common/native.h index 4f9758545ab..1bf2804db5d 100644 --- a/src/gallium/state_trackers/egl/common/native.h +++ b/src/gallium/state_trackers/egl/common/native.h @@ -69,6 +69,11 @@ struct native_probe { }; struct native_surface { + /** + * Available for caller's use. + */ + void *user_data; + void (*destroy)(struct native_surface *nsurf); /** @@ -143,6 +148,11 @@ struct native_display { */ struct pipe_screen *screen; + /** + * Available for caller's use. + */ + void *user_data; + void (*destroy)(struct native_display *ndpy); /** @@ -238,6 +248,20 @@ struct native_display_modeset { const struct native_mode *nmode); }; +/** + * The handler for events that a native display may generate.
