Subject: PCI Radeon RV100 detection hang on sparc64
Date: Thu, 6 Sep 2012 17:41:13 +0300 (EEST) [thread overview]
Message-ID: <alpine.SOC.1.00.1209061032360.371@math.ut.ee> (raw)
This is with initialyy unmodified 3.6.0-rc4-00101-g0809095 kernel in
Ultra 10 (clean, without my "Video RAM" hack that I talked in other
sparclinux posts). When I saw that Sun XVR-100 was detected fine by the
kernel, I compiled radeon drm driver with modesetting enabled and tried
it:
[drm] radeon defaulting to kernel modesetting.
[drm] radeon kernel modesetting enabled.
PCI: Enabling device: (0000:02:02.0), cmd 82
[drm] initializing kernel modesetting (RV100 0x1002:0x5159 0x1002:0x0908).
[drm] register mmio base: 0x10000000
[drm] register mmio size: 32768
[drm:radeon_device_init] *ERROR* Unable to find PCI I/O BAR
And here the machine hangs. Debugging printk-s reveal that it does not
find any active I/O port resources and then continues into initializing
the card. Down in igp_read_bios_from_vram() it successfully ioremaps
memory region 0 (vram_base=1ff08000000 and size=40000) and tries to read
2 bytes from there and hangs on reading bios[0].
With radeon.modeset=0, it boots and I collected the following info:
