Heyas folks --
It looks like nearly everything is now supported on NetBSD and the
net5501. The last major remaining issue seems to be USB 2.0; from our
ehci(4) driver:
ehci0 at pci0 dev 20 function 5: Advanced Micro Devices CS5536 EHCI
USB Controller (rev. 0x02)
ehci0: interrupting at irq 15
ehci0: pre-2.0 USB rev
The "pre-2.0 USB rev" message is displayed when PCI configuration
register 0x60 reports itself as < USB 2.0 (and as a result, the
driver fails to attach). Upon further inspection, it appears that the
firmware doesn't configure the device correctly at all -- a dump of
non-standard PCI registers for PCI 0:20:5 follows:
Device-dependent header:
0x40: 0xc8020001 0x00000000 0x00000000 0x00000000
0x50: 0x00000000 0x00000000 0x00000000 0x00000000
0x60: 0x00000000 0x00000000 0x00000000 0x00000000
0x70: 0x00000000 0x00000000 0x00000000 0x00000000
0x80: 0x00000000 0x00000000 0x00000000 0x00000000
0x90: 0x00000000 0x00000000 0x00000000 0x00000000
0xa0: 0x00000000 0x00000000 0x00000000 0x00000000
0xb0: 0x00000000 0x00000000 0x00000000 0x00000000
0xc0: 0x00000000 0x00000000 0x00000000 0x00000000
0xd0: 0x00000000 0x00000000 0x00000000 0x00000000
0xe0: 0x00000000 0x00000000 0x00000000 0x00000000
0xf0: 0x00000000 0x00000000 0x00000000 0x00000000
A read of PCI configuration register 0x60 should return 0x20 for a
USB 2.0-compliant device.
Modifying the driver to assume USB 2.0 when the USB revision register
returns 0 causes the standard EHCI driver to fail later on; as if the
firmware hasn't configured the device properly.
Is this a known issue with the shipping BIOS?
Cheers,
Jared
