I've been trying to analyze my issues with video rendering on this PC with an
intel G41 chipset.
Forgive me if my questions or observations are idiotic, but I've been trying to
understand how this
chipset is matched to a driver. And I think the mapping is expressed in the
/etc/driver_aliases file.
When I look at prtconf -v I believe the chipset is identified as
display, instance #0
Driver properties:
... stuff deleted
name='compatible' type=string items=7
value='pci8086,2e32.1458.d000.3' + 'pci8086,2e32.1458.d000'
+ 'pci1458,d000' + 'pci8086,2e32.3' + 'pci8086,2e32' + 'pciclass,030000' + 'pc
iclass,0300'
...stuff deleted
Device Minor Nodes:
dev=(99,0)
dev_path=/pci at 0,0/display at 2:text-0
spectype=chr type=minor
dev_link=/dev/fbs/text-0
dev_link=/dev/vt00
dev_link=/dev/fb
Minor properties:
name='ddi-kernel-ioctl' type=boolean dev=(99,0)
dev=(99,1)
dev_path=/pci at 0,0/display at 2:agpmaster0
spectype=chr type=minor
dev_link=/dev/agp/agpmaster0
But I cannot find any references to the "pci8086,2e32" anywhere.
So how does this chipset map to any driver. I'm not sure I understand all the
nomenclature in this output with respect the "1458" "subsystem".
I've poked into the opensolaris source and I can see where the driver_aliases
is
constructed and where most "GXX" chipsets are defined. And indeed in the
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/drm/drm_pciids.h
file there is
{0x8086, 0x2E32, CHIP_I9XX|CHIP_I965, "Intel G41"}, \
But there is no entry added to /etc/driver_aliases for "2e32" in the
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/pkgdefs/SUNWdrmr/postinstall
script which seems to reflect the /etc/drivers_aliases file on my system.
Again if I am missing something significant in this analysis, I'd appreciate a
kick in the
head. Or if it appears that I haven't read enough documentation to understand
the system
files, I'll take a pointer to some doc.
Thanks
