| |
hi all,
since 2 weeks I can't get the agpgrat-module working on my intel-i810-chipset:
00:00.0 Host bridge: Intel Corporation: Unknown device 7124 (rev 03) 00:01.0 VGA compatible controller: Intel Corporation: Unknown device 7125 (rev 03)
I can't find the reason of the initial-error while loading agpgart. ("no supported devices found"). I made some tests and changes to the module-source but I need some background-information and don't know where to find them.
In the driver, there is no case-statement for "PCI_DEVICE_ID_INTEL_810_E_1" like the one for "PCI_DEVICE_ID_INTEL_810_E_0" but the one for "810_E_0" searches for "PCI_DEVICE_ID_INTEL_810_E_1".
case PCI_DEVICE_ID_INTEL_810_E_0: i810_dev = pci_find_device(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_810_E_1, NULL);
I copied this to a new case-statement:
case PCI_DEVICE_ID_INTEL_810_E_1: ..... return intel_i810_setup(i810_dev);
but on loading of the module I get a kernel-oops in
if ((INREG32(intel_i810_private.registers, I810_DRAM_CTL) & I810_DRAM_ROW_0) == I810_DRAM_ROW_0_SDRAM) { ....
Do you have any hints for me? I have no experience in kernel-driver development but I'll try to get the driver working. Can you tell me, where to find some other usefull information? (I have the intel-datasheets, but I'm not shure, if it is a chipset-problem, a bug or just a typo in the driver). Is here anybody who has an i810-chipset with a working agpgart-driver? Please send me an "lspci-listing" an the messages while loading the driver. I want to find out the difference to my chipset.
Thank you in advance
best regards wicki
