--- Comment #19 from Michel Dänzer <michel@daenzer.net> ---
Sorry, I should have realized this earlier: The radeonsi driver is known not to
work yet on big endian hosts. That probably explains the glamor failure.

(In reply to intermediadc@hotmail.com from comment #18)
> radeon_surface.c: In function ‘si_surface_init’:
> radeon_surface.c:1614:11: warning: ‘stencil_tile_mode’ may be used

FWIW, this is probably harmless. stencil_tile_mode is only used for stencil
surfaces, the compiler isn't smart enough yet to realize that.

Thanks for the reply Michel,
i hope will be fixed because all actual gpu are using SI and this made Linux
unusable on BE host if a new machine (like is mine) .

Mesa 13.06 complete buid log

here there is my complete log of building mesa.
in this case are the mesa 13.06 i sow many warning an incompatible pointer in
SI 
hope will help to resolve the SI issue on BE

Tried Glamor on a more recent xorg stack on my PM G5 11,2 which works perfectly
well! It's on a Radeon HD 6450 however, so a r600 card and not a radeonsi as
the HD 7750.

I am running:
sys-kernel/gentoo-sources-4.9.85
x11-libs/libdrm-2.4.90
x11-drivers/xf86-video-ati-7.10.0

Only downside at the moment is that I need to run a 4.9.x kernel to get 2D/3D
acceleration 'cause of bug #99851.
