I just updated my notebook to a newer -current.
It uses
radeon0: info: VRAM: 512M 0x - 0x1FFF (512M used)
radeon0: info: GTT: 1024M 0x2000 - 0x5FFF
kern info: [drm] Detected VRAM RAM=200M, BAR=256M
kern info: [drm] RAM width 64bits DDR
Zone kernel: Available graphics memory: 1124698 kiB
kern info: [drm] radeon: 512M of VRAM memory ready
kern info: [drm] radeon: 1024M of GTT memory ready.
kern info: [drm] Loading CEDAR Microcode
kern info: [drm] Internal thermal controller without fan control
kern info: [drm] radeon: dpm initialized
kern info: [drm] GART: num cpu pages 262144, num gpu pages 262144
kern info: [drm] PCIE GART of 1024M enabled (table at 0x0025E000).
...
and it is unusable under load. I have seen the X server being killed by UVM
due to memory shortage twice in half an hour now. This never happened
with the old kernel from Oct 13.
This might be a side effect of the load being too high due to bugs in
the pkgsrc firefox build system, but I am not sure the memory preasure
really is that much higher.
We *really* need to do something about it.
