           Summary: [RADEON-KMS, Evergreen, Eyefinity 5] Invalid output on
                    4th monitor
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ishikawa@hanzubon.jp


Current Radeon KMS does not support Eyefinity 5 ?

I tested Eyefinity 5 with 4 monitors, 3 of these monitors outputs are fine,
but last monitor (4th monitor)'s output is very ugly.

Hardware setup:
 Graphic Card:
   - PowerColor Eyefinity 5 HD5770 1GB GDDR5
   - http://www.powercolor.com/Global/products_features.asp?id=240
   - This Graphic card has 5 mini DisplayPorts

 Monitors:
  2 x HYUNDAI W240D
   - Resolution: 1920x1200
   - connected to the card with mini-DP to Dual Link DVI passive convertor
     (this cable included the graphic card package)

  2 x BenQ G2400DW
   - Resolution: 1920x1200
   - connected to the card with mini-DP to DP cable (included the package)
     and DP to DVI active convertor (This one
     http://akiba-pc.watch.impress.co.jp/hotline/20100529/ni_cawesome.html
     this is a Japanese page. Sorry, I can not find English informations)

Software setup:
 Linux kernel version 2.6.36-rc3
 (from linus git tree, commit 2bfc96a127bc1cc94d26bfaa40159966064f9c8c)


 * Output images are attached.
   Picture 1 is monitor connected mini-DP port 1. It is a normal output of
   'ps aux on linux console'. Monitors connected on port 2 and port 3 are some
as
   this one.
   Picture 2 is monitor conncted port 4 on the same time. I saw some kind of
   timing problem with noises.


 * On xf86-driver-ati (evergreen git branch) with individual output on all
monitors
   xrandr setup, monitor 1,2,3's output are correct. But Monitor 4's output is
   same as Monitor 3 with some kind of timeing problem (timing problem and
noises looks
   same as KMS console display).
   So, I think monitor 4 output on KMS is same as monitor 3 with some timing
glitch.


 * A monitor connected largest number of port is ugly when 4 monitors are
connected.
   When connected with only 3 monitors, these are fine.
   Ugly output is not depend on a kind of links and port.

   For example: (DP means connected with active convertor on this setting)

    Port 1 -> DVI1
    Port 2 -> DVI2
    Port 3 -> DP1
    Port 4 -> DP2
    Port 5 -> none

      Problem on DP2 monitor only



    Port 1 -> DVI1
    Port 2 -> DVI2
    Port 3 -> DP1
    Port 4 -> none
    Port 5 -> DP2

      Problem on DP2 monitor only



    Port 1 -> DP1
    Port 2 -> DP2
    Port 3 -> DVI1
    Port 4 -> DVI2
    Port 5 -> none

      Problem on DVI2 monitor only



    Port 1 -> DP1
    Port 2 -> DVI1
    Port 3 -> DP2
    Port 4 -> DVI2
    Port 5 -> none

      Problem on DVI2 monitor only



    Port 1 -> DP1
    Port 2 -> DVI1
    Port 3 -> DVI2
    Port 4 -> none
    Port 5 -> DP2

      Problem on DP2 monitor only



    Port 1 -> DP1
    Port 2 -> DVI1
    Port 3 -> DP2
    Port 4 -> DVI2
    Port 5 -> none

      Problem on DVI2 monitor only



    Port 1 -> DVI1
    Port 2 -> DVI2
    Port 3 -> DP1
    Port 4 -> none
    Port 5 -> none

      All 3 monitors are fine.



    Port 1 -> DVI1
    Port 2 -> DVI2
    Port 3 -> none
    Port 4 -> DP1
    Port 5 -> none

      All 3 monitors are fine.



    Port 1 -> DVI1
    Port 2 -> none
    Port 3 -> none
    Port 4 -> DVI2
    Port 5 -> DP1

      All 3 monitors are fine.


 * I know the Eyefinity restriction(related clock source). 2 of 4 monitor are
linked
   with DisplayPort (with Active DVI convertor), other 2 are linked with DVI.
These
   link settings are OK for Eyefinity 5. I checked this link config does works
on
   Windows 7 (Individual Items are displyed on each monitor).

 * I think it is not a hardware problem. Monitors and link cables, active
convetor
   exchange each other is not effect on the problems. And all hardwares works
fine
   on other Graphic cards or Other OSs (e.g Windows).
