[gentoo-ppc-user] Are there any Pegasos users?

[Johannes Geiss]

Hi here,

are there any Pegasos users using Gentoo?

Especially the hardware platform Pegasos II?

I am looking for experiences about building an own kernel for this
architecture. I compile them by myself for some years, but I think I could
be better if I find someone else who is building kernels for Pegasos
II. I am interested to exchange/talk about config files and so on.

Unfortunately Gentoo seems to have dropped kernel support for Pegasos
for some years. No installation disk contains a kernel for this
hardware.

Bye
Johannes

Re: [gentoo-ppc-user] Pegasos II + Radeon 9000: No DRI and wrong colours for OpenGL

I did a little investigation of my problem and saw this:

xorg-server-1.5.3-r6 has a library called libglx.so. This library uses 

drmOpenOnce(NULL, "pci:0001:01:08.0", ...)

to get the graphics card.

lspci reports

0001:01:08.0 VGA compatible controller:
ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01)

So the PCI Bus ID seems to be correct.

libdrm-2.4.5 has the function drmOpenOnce(). This function goes down to
drmOpen(NULL, "pci:0001:01:08.0") and
drmOpenByBusid("pci:0001:01:08.0").

Now drmGetBusid(fd) is called and returns "pci::01:08.0". Which is
wrong, because it differs from the original PCI Bus ID. So my graphics
card will not be used with hardware accelerated OpenGL.

drmGetBusid() calls the kernel module drm via IOCTL
DRM_IOCTL_GET_UNIQUE. (see file drm_ioc32.c). So is it a bug in the
kernel? Whom can I report this?

Thanks for any suggestions
Johannes

[gentoo-ppc-user] Pegasos II + Radeon 9000: No DRI and wrong colours for OpenGL

[Johannes Geiss]

Hi there,

I updated my xorg-server to the latest version 1.5.3-r6 and now my X11
performance for OpenGL (Mesa 7.3-r1) is bad and has wrong colours (eg.
glxgears).

grep -e "\[drm\]" Xorg.0.log

(II) [drm] DRM interface version 1.3
(II) [drm] DRM open master succeeded.
(II) RADEON(0): [drm] Using the DRM lock SAREA also for drawables.
(II) RADEON(0): [drm] framebuffer handle = 0xc000
(II) RADEON(0): [drm] added 1 reserved context for kernel
(II) RADEON(0): [drm] installed DRM signal handler
(II) RADEON(0): [drm] register handle = 0x2900
(II) RADEON(0): [drm] Added 32 65536 byte vertex/indirect buffers
(II) RADEON(0): [drm] Mapped 32 vertex/indirect buffers
(II) RADEON(0): [drm] failure adding irq handler, there is a device
already using that irq
[drm] falling back to irq-free operation
(II) RADEON(0): [drm] Initialized kernel GART heap manager, 5111808

grep -e "^(EE)" Xorg.0.log

(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) AIGLX error: drmOpenOnce failed (Operation not permitted)
(EE) AIGLX: reverting to software rendering
(EE) PreInit returned NULL for "MOSIC  SPEED-LINK Competition Pro"
(EE) config/hal: NewInputDeviceRequest failed
(EE) PreInit returned NULL for "MOSIC  USB 2A4K  GamePad"
(EE) config/hal: NewInputDeviceRequest failed

It seems to be a problem with AIGLX (drmOpenOnce failed). But I have

Section "DRI"
Mode 0666
EndSection

and

Option  "BusType"   "PCI"

in my xorg.conf

Does anybody have a suggestion?

Thanks for any help
Johannes
