Hello!
I've tried fresh (as of 24-Dec-2005) CURRENT on my ASUS M5A notebook
(based on Intel 915GM Express chipset), and got a problem with agp
module attachment. Here is the relevant part of pciconf -lv:
hostb0@pci0:0:0: class=0x060000 card=0x19971043 chip=0x25908086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82915PM/GM/GMS, 82910GML Host Bridge'
class = bridge
subclass = HOST-PCI
vgapci0@pci0:2:0: class=0x030000 card=0x18821043 chip=0x25928086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82915GM/GMS, 82910GML Integrated Graphics Device'
class = display
subclass = VGA
vgapci1@pci0:2:1: class=0x038000 card=0x18821043 chip=0x27928086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82915GM/GMS,82910GML Mobile Express Family Graphics
Controller (??)'
class = display
I've tried both to compile devices agp,drm,i915 to the kernel and load them
via /boot/loader.conf - result with the stock kernel was the same:
vgapci0: <VGA-compatible display> port 0xec00-0xec07 mem
0xfeb80000-0xfebfffff,0xd0000000-0xdfffffff,0xfeb40000-0xfeb7ffff irq 16
at device 2.0 on pci0
drm0: <Intel i915GM> on vgapci0
error: [drm:pid0:drm_load] *ERROR* Card isn't AGP, or couldn't initialize AGP.
device_attach: drm0 attach returned 12
I had to hack /sys/dev/pci/vga_pci.c:
--- vga_pci.c.orig Thu Dec 22 18:25:22 2005
+++ vga_pci.c Sun Dec 25 13:04:09 2005
@@ -74,7 +74,7 @@

- if (pci_find_extcap(dev, PCIY_AGP, NULL) == 0)
+// if (pci_find_extcap(dev, PCIY_AGP, NULL) == 0)
device_add_child(dev, "agp", -1);
in order to get proper (I hope!) attachment of agp and drm:
vgapci0: <VGA-compatible display> port 0xec00-0xec07 mem
0xfeb80000-0xfebfffff,0xd0000000-0xdfffffff,0xfeb40000-0xfeb7ffff irq 16
at device 2.0 on pci0
agp0: <Intel 82915GM (915GM GMCH) SVGA controller> on vgapci0
agp0: detected 7932k stolen memory
agp0: aperture size is 256M
drm0: <Intel i915GM> on vgapci0
info: [drm] AGP at 0xfeb80000 0MB
info: [drm] Initialized i915 1.2.0 20041217
Why doesn't vgapci want to attach an agp module on my notebook? What relevant
info should I dig further?
P.S. Here is my kernel config:
