From acd35c8758dc732409035cb0488c9d1c896f636d Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Thu, 25 Aug 2016 14:28:48 +0100 Subject: egl/android: tweak droid_add_configs_for_visuals() Iterate over the driver_configs first in order to cut down the number of getConfigAttrib() calls by a factor of 5. While we're here, also drop the sentinel of the visuals array. We already know its size so we can use that and save a few bytes. v2: Use correct comparison in loop conditional (Eric) Use valid C initializer (Gurchetan) Signed-off-by: Emil Velikov Reviewed-by: Eric Engestrom --- src/egl/drivers/dri2/platform_android.c | 40 +++++++++++++++++---------------- 1 file changed, 21 insertions(+), 19 deletions(-) (limited to 'src/egl/drivers/dri2/platform_android.c') diff --git a/src/egl/drivers/dri2/platform_android.c b/src/egl/drivers/dri2/platform_android.c index ac9072a..6a4122a 100644 --- a/src/egl/drivers/dri2/platform_android.c +++ b/src/egl/drivers/dri2/platform_android.c @@ -760,7 +760,6 @@ droid_add_configs_for_visuals(_EGLDriver *drv, _EGLDisplay *dpy) { HAL_PIXEL_FORMAT_RGB_888, { 0xff, 0xff00, 0xff0000, 0x0 } }, { HAL_PIXEL_FORMAT_RGB_565, { 0xf800, 0x7e0, 0x1f, 0x0 } }, { HAL_PIXEL_FORMAT_BGRA_8888, { 0xff0000, 0xff00, 0xff, 0xff000000 } }, - { 0, { 0, 0, 0, 0 } } }; EGLint config_attrs[] = { EGL_NATIVE_VISUAL_ID, 0, @@ -771,38 +770,41 @@ droid_add_configs_for_visuals(_EGLDriver *drv, _EGLDisplay *dpy) EGL_MAX_PBUFFER_HEIGHT, _EGL_MAX_PBUFFER_HEIGHT, EGL_NONE }; + unsigned int format_count[ARRAY_SIZE(visuals)] = { 0 }; int count, i, j; count = 0; - for (i = 0; visuals[i].format; i++) { - int format_count = 0; + for (i = 0; dri2_dpy->driver_configs[i]; i++) { + const EGLint surface_type = EGL_WINDOW_BIT | EGL_PBUFFER_BIT; + struct dri2_egl_config *dri2_conf; + unsigned int double_buffered = 0; - config_attrs[1] = visuals[i].format; - config_attrs[3] = visuals[i].format; + dri2_dpy->core->getConfigAttrib(dri2_dpy->driver_configs[i], + __DRI_ATTRIB_DOUBLE_BUFFER, &double_buffered); - for (j = 0; dri2_dpy->driver_configs[j]; j++) { - const EGLint surface_type = EGL_WINDOW_BIT | EGL_PBUFFER_BIT; - struct dri2_egl_config *dri2_conf; - unsigned int double_buffered = 0; + /* support only double buffered configs */ + if (!double_buffered) + continue; - dri2_dpy->core->getConfigAttrib(dri2_dpy->driver_configs[j], - __DRI_ATTRIB_DOUBLE_BUFFER, &double_buffered); + for (j = 0; j < ARRAY_SIZE(visuals); j++) { + int format_count = 0; - /* support only double buffered configs */ - if (!double_buffered) - continue; + config_attrs[1] = visuals[j].format; + config_attrs[3] = visuals[j].format; - dri2_conf = dri2_add_config(dpy, dri2_dpy->driver_configs[j], - count + 1, surface_type, config_attrs, visuals[i].rgba_masks); + dri2_conf = dri2_add_config(dpy, dri2_dpy->driver_configs[i], + count + 1, surface_type, config_attrs, visuals[j].rgba_masks); if (dri2_conf) { count++; - format_count++; + format_count[j]++; } } + } - if (!format_count) { + for (i = 0; i < ARRAY_SIZE(format_count); i++) { + if (!format_count[i]) { _eglLog(_EGL_DEBUG, "No DRI config supports native format 0x%x", - visuals[i].format); + visuals[i].format); } } -- cgit v1.1
