FreeBSD ***** 4.1.1-STABLE FreeBSD 4.1.1-STABLE #0: Thu Sep 28 18:03:48 CEST 2000 ***@******:/mnt/install/src/sys/compile/kernel i386
>Description:
The SiS630E (recognized as SiS 5591) Driver will do only UDMA33.
>How-To-Repeat:
Install FreeBSD on a ASUS CUSI-FX with UDMA66-Disk.
>Fix:
Its not a fix but adds UDMA66 to the SiS 5591 for the
primary master.
Dont use a UDMA33-Device there because it will fallback
to plain PIO later and I dont know where to fix this...
Bonnie shows no difference between UDMA33 and UDMA66.
Insert the following in sys/dev/ata/ata-dma.c just bevore line #409:
if (udmamode >= 4 && scp->unit == 0 && device == ATA_MASTER ) {
error = ata_command(scp, device, ATA_C_SETFEATURES, 0, 0, 0,
ATA_UDMA4, ATA_C_F_SETXFER, ATA_WAIT_READY);
if (bootverbose)
ata_printf(scp, device, "%s setting UDMA4 on SiS chip\n",
(error) ? "failed" : "success");
if (!error) {
pci_write_config(parent, 0x40 + (devno << 1), 0xa301, 2);
scp->mode[ATA_DEV(device)] = ATA_UDMA4;
return;
}
}
From /var/run/dmesg.boot:
