* e1000e: don't inadvertently re-set INTX_DISABLEDean Nelson2010-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Should e1000_test_msi() fail to see an msi interrupt, it attempts to fallback to legacy INTx interrupts. But an error in the code may prevent this from happening correctly. Before calling e1000_test_msi_interrupt(), e1000_test_msi() disables SERR by clearing the SERR bit from the just read PCI_COMMAND bits as it writes them back out. Upon return from calling e1000_test_msi_interrupt(), it re-enables SERR by writing out the version of PCI_COMMAND it had previously read. The problem with this is that e1000_test_msi_interrupt() calls pci_disable_msi(), which eventually ends up in pci_intx(). And because pci_intx() was called with enable set to 1, the INTX_DISABLE bit gets cleared from PCI_COMMAND, which is what we want. But when we get back to e1000_test_msi(), the INTX_DISABLE bit gets inadvertently re-set because of the attempt by e1000_test_msi() to re-enable SERR. The solution is to have e1000_test_msi() re-read the PCI_COMMAND bits as part of its attempt to re-enable SERR. During debugging/testing of this issue I found that not all the systems I ran on had the SERR bit set to begin with. And on some of the systems the same could be said for the INTX_DISABLE bit. Needless to say these latter systems didn't have a problem falling back to legacy INTx interrupts with the code as is.

* 3c59x: Specify window explicitly for access to windowed registersBen Hutchings2010-06-29
| | | | | | | | | | | | | | | | | | | Currently much of the code assumes that a specific window has been selected, while a few functions save and restore the window. This makes it impossible to introduce fine-grained locking. Make those assumptions explicit by introducing wrapper functions to set the window and read/write a register. Use these everywhere except vortex_interrupt(), vortex_start_xmit() and vortex_rx(). These set the window just once, or not at all in the case of vortex_rx() as it should always be called from vortex_interrupt(). Cache the current window in struct vortex_private to avoid unnecessary hardware writes.

* dccp: make implementation of Syn-RTT symmetricGerrit Renker2010-06-26
| | | | | | | | | | | | | | | | | | This patch is thanks to Andre Noll who reported the issue and helped testing. The Syn-RTT sampled during the initial handshake currently only works for the client sending the DCCP-Request. TFRC penalizes the absence of an RTT sample with a very slow initial speed (1 packet per second), which delays slow-start significantly, resulting in sluggish performance. This patch mirrors the "Syn RTT" principle by adding a timestamp also onto the DCCP-Response, producing an RTT sample when the (Data)Ack completing the handshake arrives. Also changed the documentation to 'TFRC' since Syn RTTs are also used by CCID-4. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
