Reply With QuoteThe AGP 3850 card uses a PCIE GPU combined with a PCIE-to-AGP bridge chip, so it may use MSI interrupts between the GPU and the bridge chip, not sure.
If you enable MSI in the kernel does the error message go away ?

HD 3850 agp
Hi. I have this video card and Gentoo Linux. I downloaded driver from AMD site, installed it and get very high load cpu X in windows operations (60%-90%). I apply "backclear" patch and load cpu decreased, but not all windows operations. Now i install "radeon" driver and load cpu 20%-30%. I try install ati-driver from Gentoo portage and get this message:
But i have agp card. Why PCI_MCI? What to do?* You have DRM support built in to the kernel
* Direct rendering will not work.
* ati-drivers-9.11 requires MSI in the kernel.
* Please enable it:
* CONFIG_PCI_MSI=y
* in /usr/src/linux/.config or
* Bus options (PCI etc.) --->
*[*] Message Signaled Interrupts (MSI and MSI-X)
* in the kernel config.
*
* ERROR: x11-drivers/ati-drivers-9.11 failed.

I have not found CONFIG_PCI_MSI in .config. Kernel 2.6.30Originally Posted by bridgman

If it's left unchecked in the kernel config, it's doubtful that you will find it in the .config file.

Add manually?

Using xconfig is probably the easiest.

I can`t find this in menuconfig too.

make menuconfig
hit the '/' key and search for MSI

Select Local APIC support on uniprocessors and see if it shows up.
