| |
For a while, I've been having this on my dmesg:
agpgart: Xorg tried to set rate=x12. Setting to AGP3 x8 mode. agpgart: Putting AGP V2 device at 0000:00:00.1 into 2x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 2x mode [drm] Loading R200 Microcode
This is really weird since my motherboard (CNB20HE chipset) only supports 2x AGP cards and my xorg.conf file has this:
Section "Device" Identifier "RADEON9200SE" Driver "radeon" Option "AGPMode" "2" EndSection
Looking at the code I found out that the code path being run to get this printk is: ------------------------------------------------------------------ /* Check to see if we are operating in 3.0 mode */ if (agp_bridge->mode & AGPSTAT_MODE_3_0) agp_v3_parse_one(&requested_mode, &bridge_agpstat, &vga_agpstat); <---------- else agp_v2_parse_one(&requested_mode, &bridge_agpstat, &vga_agpstat); ------------------------------------------------------------------
so it looks like agp_brige->mode is not being initializated properly, it is sworks-agp.c:serverworks_configure() who initializates it in my box so something has to be wrong with one of these 2 lines?: ------------------------------------------------------------------ agp_bridge->capndx = pci_find_capability(serverworks_private.svrwrks_dev, PCI_CAP_ID_AGP);
/* Fill in the mode register */ pci_read_config_dword(serverworks_private.svrwrks_dev, agp_bridge->capndx+PCI_AGP_STATUS, &agp_bridge->mode); ------------------------------------------------------------------
What is going on, is this a know bug, should I just ignore it (it doesn't harms anything), file a bugzilla bug? My dmesg says: Linux agpgart interface v0.101 (c) Dave Jones agpgart: AGP aperture is 128M @ 0xd0000000 agpgart: Detected ServerWorks CNB20HE chipset: No AGP present. agpgart: Detected ServerWorks CNB20HE chipset: No AGP present.
Full lspci output is included.
