Hi all,
My test machine has an Nvidia plugin card that I'm using with the free software nv driver.
I've attached a diff between the Xorg.0.log file booted into the proprietary BIOS, and into LinuxBIOS (Xorg.diff). These are the most interesting bits (lines starting with + are LinuxBIOS):
GeForce Go 7900 GTX, Quadro FX 2500M, Quadro FX 1500M, GeForce 6150, GeForce 6150 LE, GeForce 6100, GeForce Go 6150, GeForce Go 6100 (II) Primary Device is: PCI 02:00:0 +(WW) NV: No matching Device section for instance (BusID PCI:0:1:3) found (--) Chipset Unknown NVIDIA chip found (II) resource ranges after xf86ClaimFixedResources() call:
This PCI:0:1:3 device is new. It didn't exist under the proprietary BIOS, and is identified as such by lspci:
0000:00:01.3 Co-processor: nVidia Corporation: Unknown device 036b (rev a2)
and lspci -n
0000:00:01.3 0b40: 10de:036b (rev a2)
What is this thing? A co-processor?
The other interesting difference is:
(II) Reloading /usr/lib/xorg/modules/libint10.so (II) NV(0): Initializing int10 -(II) NV(0): Primary V_BIOS segment is: 0xc000 +(EE) NV(0): V_BIOS address 0x420 out of range (--) NV(0): Chipset: "Unknown NVIDIA chipset" (**) NV(0): Depth 24, (--) framebuffer bpp 32
Not sure if it is related, but there is a 30+ second delay in the X startup at this point:
(II) Loading sub module "ddc" (II) LoadModule: "ddc" (II) Reloading /usr/lib/xorg/modules/libddc.so (II) NV(0): I2C bus "DDC" initialized. (II) NV(0): Probing for analog device on output A... (--) NV(0): ...can't find one (II) NV(0): Probing for analog device on output B... (--) NV(0): ...can't find one (II) NV(0): Probing for EDID on I2C bus A... (II) NV(0): I2C device "DDC:ddc2" registered at address 0xA0.
...... very long delay .......
(II) NV(0): I2C device "DDC:ddc2" removed. (--) NV(0): DDC detected a DFP: (II) NV(0): Manufacturer: SAM Model: 1ae Serial#: 1112683056
Any ideas as to what's going on here?
Hints greatly appreciated, as always.
Thanks, Ward.

Is some IPMI processor, We could disable it.... but it doesn't hurt.

To follow up on my own message, I have traced the problem down to the xf86DoEDID_DDC2 function in X11, which lives in hw/xfree86/ddc/xf86DDC.c in the xorg source tree.
If I disable DDC2 in my xorg.conf file like this:
Section "Device" ... Option "NoDDC2" ... EndSection
the delay is gone.
So - is this a driver issue, or a LinuxBIOS issue?
Thanks, Ward.
It seems some code is doing probe via I2C. Maybe some I2C need to set for it.
