I'm evaluating the radeon driver on my card with rawhide.<br>It is a Sapphire X1900 crossfire edition card, that has 512MB of memory:<br><br>lspci -v<br>01:00.0 VGA compatible controller: ATI Technologies Inc R580 [Radeon X1900 XT] (Primary) (prog-if 00 [VGA controller])<br>
Subsystem: ATI Technologies Inc Unknown device 0d02<br>
Flags: bus master, fast devsel, latency 0, IRQ 16<br> Memory at 80000000 (64-bit, prefetchable) [size=256M]<br> Memory at 90200000 (64-bit, non-prefetchable) [size=64K]<br> I/O ports at 2000 [size=256]<br>
Expansion ROM at 90220000 [disabled] [size=128K]<br> Capabilities: [50] Power Management version 2<br> Capabilities: [58] Express Endpoint, MSI 00<br> Capabilities: [80] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-<br>
<br>01:00.1 Display controller: ATI Technologies Inc R580 [Radeon X1900 XT] (Secondary)<br> Subsystem: ATI Technologies Inc Unknown device 0d03<br> Flags: bus master, fast devsel, latency 0<br> Memory at 90210000 (64-bit, non-prefetchable) [size=64K]<br>
Capabilities: [50] Power Management version 2<br> Capabilities: [58] Express Endpoint, MSI 00<br><br>At the end of March I could use only text installer in rawhide because both vesa and radeon drivers failed to load.<br>
With latest updates ( anaconda-11.4.0.71-1 ) radeon driver is successfully used and loads during installation. Well!<br>In the system, after install, I see this in my Xorg log:<br><br><br>(II) RADEON(0): Detected total video RAM=524288K, accessible=262144K (PCI BAR=262144K)<br>
(--) RADEON(0): Mapped VideoRAM: 262144 kByte (64 bit DDR SDRAM)<br>
<br>So it seems I only use half the available memory, correct?<br>How to get rid of this problem, in case?<br>I'm using EXA accel method because it is the only one that allows xvideo with radeon driver.<br>And it seems stable, at least on my configuration, but it is not the default one at the moment...<br>
