Hello
I am testing the new dpm code on my RV730 card:
$ lspci -v
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI
RV730/M96 [Mobility Radeon HD 4650/5165] (prog-if 00 [VGA controller])
Subsystem: COMPAL Electronics Inc Device 003e
Flags: bus master, fast devsel, latency 0, IRQ 50
Memory at d0000000 (32-bit, prefetchable) [size=256M]
I/O ports at 2000 [size=256]
Memory at cfef0000 (32-bit, non-prefetchable) [size=64K]
[virtual] Expansion ROM at cfe00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: radeon
The screen constantly flickers, everytime I interact with the computer like
moving the mouse og touching the keyboard. If I don't interact the computer,
the flickering is alot less. If I boot without radeon.dpm=1, the flicker
dissapears.
The flickering is best descripted as if the screen is jumping up and down very
fast.
Using the latest ucode for my card:
- R700_rlc.bin
- RV730_smc.bin
- RV730_pfp.bin
Using Xorg edgers in Ubuntu 13.04.
Using Ubuntu drm-next kernel:
<a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-07-04-saucy/">http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-07-04-saucy/</a>
Git: 69163ea82732894e8c1e17df4010372ed078efdd
Attached dmesg, but there is no errors to be seen.</pre>
