Substractive Resource
by Li-Ta Lo 03 Dec '04

03 Dec '04

Eric, You explained substractive decoding to me long time ago but I really forgot what it is. Could you tell me again ? Hoe do you determine if some resource of some device is substractive ? Form the data sheet ? Ollie

amd8111_nic fix
by Liu Tao 02 Dec '04

02 Dec '04

Hello, On my board I have amd8111 nic + realtek 8201 PHY, but 8111nic use active high reset signal to reset PHY while RTL8201 accepts active low reset signal. However amd8111 nic provides PHY_RESET_POLARITY bit in CMD3 register, so I add the "phy_lowreset" register to handle this. attached is the patch. Regards, Liu Tao

I don't know about need but I think it could be handy to have. Especially as we don't have many users of i2c code in the tree at the present time. Eric

devices/pci_devices.c
by mark.wilkinson＠2pmtech.com 02 Dec '04

Hi Eric, Ron, I noticed what might be a slight problem with some error messages in the pci_level_irq routine. When it reports the new settings, it masks off the lower nibble of intBits to compare against the byte read. If an interrupt line is set in the upper nibble of the byte, then the error message will always be displayed even if the setting was successful. I've included a diff that should fix the masks. Regards Mark Wilkinson. ---------------------------------------------------------------- This message was sent using ISPMailNow.com

irq routing table
by Gin 01 Dec '04

01 Dec '04

If I have a wrong checksum for my irq routing table, would that stops me from booting successfully? The question should be, does the irq_routing table matter at all? Linuxbios runs through till it jumps to the entry of payload. I am just trying to figure out why. Gin
