Dear All,
Sorry for such a big mail, i just want to put in detailed.
I am trying for hardware acceleration on Mesa 7.8.2 on RHEL6 which has kernel
version 2.6.32.
I compiled mesa with below configurations.
./configure --enable-gles2 --enable-egl --with-egl-platforms=drm
--with-dri-drivers=i965 --disable-glw --with-state-trackers=egl,dri,es
--enable-gallium-intel
it generated the below list of libraries

Runing my test application, i got below error
[srini at RHEL2 check_GLES]$ ./sphere
libEGL fatal: DRI2: did not find extension DRI_IMAGE version 1
then i changed few stuff in the file egl_dri2.c. the changes are this.
static struct dri2_extension_match dri2_core_extensions[] = {
{ __DRI2_FLUSH, 1, offsetof(struct dri2_egl_display, flush) },
{ __DRI_TEX_BUFFER, 2, offsetof(struct dri2_egl_display, tex_buffer) },
{ NULL },
{ __DRI_IMAGE, 1, offsetof(struct dri2_egl_display, image) }
};
originally it was like this.
static struct dri2_extension_match dri2_core_extensions[] = {
{ __DRI2_FLUSH, 1, offsetof(struct dri2_egl_display, flush) },
{ __DRI_TEX_BUFFER, 2, offsetof(struct dri2_egl_display, tex_buffer) },
{ __DRI_IMAGE, 1, offsetof(struct dri2_egl_display, image) },
{ NULL }
};
I changed this after seeing the below structure in the file dri_screen.c
static const __DRIextension *dri_screen_extensions[] = {
&driReadDrawableExtension,
&driCopySubBufferExtension.base,
&driSwapControlExtension.base,
&driFrameTrackingExtension.base,
&driMediaStreamCounterExtension.base,
&dri2TexBufferExtension.base,
&dri2FlushExtension.base,
NULL
};
which actually loads the dri_extension, doesn't have entry for image_extension.
with this change build,eglInitilization is successfull. which actually create
the screen, configurations everything.
but the application when comming to eglChooseConfig(), it could not find the
matching EGL attributes. below is my attribute list my application is quering
for.
static const EGLint attribs[] = {
EGL_RED_SIZE, 1,
EGL_GREEN_SIZE, 1,
EGL_BLUE_SIZE, 1,
EGL_DEPTH_SIZE, 1,
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
EGL_NONE
};
and i am endup with the error.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
but this application working fine if i set
EGL_DRIVER=/usr/local/lib/egl/egl_x11_i965.so
so, i seriously think it must be the bug from i965_dri2.so.
i am peeking in to the code as much as i do, and ends clueless.
please anyone confirm me where it is going wrong.
glade to give more details.
Thanking you.
Srini.
