Radeon HD 5450 support?

I installed a new ati hd 5450 on debian amd64, and the new sdk 2.01

all the opencl samples are working with --device cpu, but with gpu :

Error: clCreateContextFromType failed. Error code : CL_DEVICE_NOT_FOUND

what can i do to fix this?

Which version of debian are you using? Did you install the drivers ? Could you run the CAL sample 'FindNumDevices' to see if the driver is installed properly and devices are being detected.?


i am using debian lenny x64 with kernel 2.6.33-2-amd64

i downloaded the drivers this friday :

(II) LoadModule: "fglrx"
(II) Loading /usr/lib/xorg/modules/drivers//
(II) Module fglrx: vendor="FireGL - ATI Technologies Inc."
        compiled for 7.1.0, module version = 8.70.3
        Module class: X.Org Video Driver
(II) Loading sub module "fglrxdrm"
(II) LoadModule: "fglrxdrm"
(II) Loading /usr/lib/xorg/modules/linux//
(II) Module fglrxdrm: vendor="FireGL - ATI Technologies Inc."
        compiled for 7.1.0, module version = 8.70.3

CAL Finddevices says:

Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.553
Use -? for help
CAL initialized.
Finding out number of devices :-
Device Count = 0
CAL shutdown successful.

aticonfig finds:

* 0. 01:00.0 ATI Radeon HD 5400 Series

* - Default adapter


i guess, it can't compile the driver, because i dont have the linux-headers installed

but it should work, isn't? i mean, it is supported in linux?



Catalyst driver supports Linux(OpenSUSE 11.0, Ubuntu 9.10 and RHEL 5.3 are the officially supported versions.)



ok, it worked without problems

you need to compile the module. The installer said nothing about that, but it complies the module. I suggest to report this in some way.

after that, i ran aticonfig, and the server was properly configured.

I run a linux box connected with ssh, with the xserver installed in a chroot jail (only the xserver). I is important for me to keep the install minimal, as i want to run apps that dont need x-window, while

so, execute xinit to start a dummy xserver, and then, you can connect with ssh, and run opencl commands. But it is important that:

export DISPLAY=":0"
