2006-12-26PHY probe not working properly for ibm_emac (PPC4xx)Hynek Petrak
I have a system with AMCC PowerPC 405EP and PHY Intel LXT971A. Linux 2.6.18.3 is not able to detect the PHY ID correctly. The PHY ID detected is 0, but should be 0x1d. This is because phy_read() (__emac_mdio_read() resp.) from drivers/net/ibm_emac/ibm_emac_core.c might return -ETIMEDOUT or -EREMOTEIO on error. This is ignored inside the int mii_phy_probe(struct mii_phy *phy, int address) from drivers/net/ibm_emac/ibm_emac_phy.c as the return value is assigned to an u32 variable.

It is really a bug in the base power management resume code, and this workaround is temporary until the change to PM code works it's way through the release process.

2006-12-26e1000: Do not truncate TSO TCP header with 82544 workaroundHerbert Xu
The e1000 driver has a workaround for 82544 on PCI-X where if the terminating byte of a buffer is at addresses 0-3 mod 8, then 4 bytes are shaved off it and defered to a new segment. This is due to an erratum that could otherwise cause TX hangs. Unfortunately this breaks TSO because it may cause the TCP header to be split over two segments which itself causes TX hangs. The solution is to pull 4 bytes of data up from the next segment rather than pushing 4 bytes off. This ensures the TCP header remains in one piece and works around the PCI-X hang. This patch is based on one from Jesse Brandeburg. This bug has been trigered by both CONFIG_DEBUG_SLAB as well as Xen. Note that the only reason we don't see this normally is because the TCP stack starts writing from the end, i.e., it writes the TCP header first then slaps on the IP header, etc. So the end of the TCP header (skb->tail - 1 here) is always aligned correctly. Had we made the start of the IP header (e.g., IPv6) 8-byte aligned instead, this would happen for normal TCP traffic as well.

2006-12-26myri10ge: move request_irq to myri10ge_openBrice Goglin

2006-12-26myri10ge: match number of save_state and restoreBrice Goglin
Since pci_save_state() pushes MSI and PCIe states on a kind of stack, myri10ge saving the state in advance for parity recovery will push the state again on the stack on suspend. This leads to some memory leak. We add a couple additional calls to save_state and restore_state so that we don't leak anymore. For the future, we are thinking of a better way to recover from parity error without using pci_save_state(). Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-12-26[PATCH] e1000: No-delay link detection at interface upJesse Brandeburg
Currently after an interface up, the link state is detected 2 seconds later when the first watchdog timer runs. This patch changes that by triggering the hardware to generate a link-change interrupt from the up() function instead. This has the result that the link state gets detected immediately and without races. This has the potential to speed up booting since a normal distribution boot process waits for a link before DHCP is attempted.

We use the fixmap for accessing pci config space in pci_mmcfg_read/write(). The problem is in pci_exp_set_dev_base().

So, second pci_mmcfg_read() on cpu0 accesses a device-A via a previous TLB cache. This problem became the cause of several strange behavior. This patches fixes this situation by adds "mmcfg_last_accessed_cpu" check. [ Alternatively, we could make a per-cpu mapping area or something.
