2010-03-01sata_via: Correctly setup PIO/DMA for pata slave on vt6421.Bart Hartgers1-3/+5
Before only the timings for master were set. Datasheet can be found here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF Surprisingly, a slave drive works without this patch. According to the datasheet, the controller by default derives the DMA mode from the Set Features command issued to a drive. Not sure about the PIO timings, though. The real problem is that the timings for the master effectively are the ones tuned for the slave. If these support different UDMA-settings, there is trouble, especially when the slave supports a higher UDMA than the master. Anyhow, using the same mechanism for both master and slave seems like a good idea.

2010-03-01libata: implement spurious irq handling for SFF and apply it to piixTejun Heo2-8/+47
Traditional IDE interface sucks in that it doesn't have a reliable IRQ pending bit, so if the controller raises IRQ while the driver is expecting it not to, the IRQ won't be cleared and eventually the IRQ line will be killed by interrupt subsystem. Some controllers have non-standard mechanism to indicate IRQ pending so that this condition can be detected and worked around. This patch adds an optional operation ->sff_irq_check() which will be called for each port from the ata_sff_interrupt() if an unexpected interrupt is received. If the operation returns %true, ->sff_check_status() and ->sff_irq_clear() will be cleared for the port. Note that this doesn't mark the interrupt as handled so it won't prevent IRQ subsystem from killing the IRQ if this mechanism fails to clear the spurious IRQ. This patch also implements ->sff_irq_check() for ata_piix. Note that this adds slight overhead to shared IRQ operation as IRQs which are destined for other controllers will trigger extra register accesses to check whether IDE interrupt is pending but this solves rare screaming IRQ cases and for some curious reason also helps weird BIOS related glitch on Samsung n130 as reported in bko#14314. http://bugzilla.kernel.org/show_bug.cgi?id=14314 * piix_base_ops dropped as suggested by Sergei. * Spurious IRQ detection doesn't kick in anymore if polling qc is in progress. This provides less protection but some controllers have possible data corruption issues if the wrong register is accessed while a command is in progress.

There's no need to clear the fast interrupt bit in hpt366_set_mode() since we're doing it in hpt366_init_chipset() already. While at it, rename 'addr1' local variable to 'addr' and exclude 'ap->port_no' from its calculation as HPT36x are single-channel-per-function chips.

2010-03-01pata_hpt{37x|3x2n}: unify mode programmingSergei Shtylyov2-116/+90
As these drivers' set_piomode() and set_dmamode() methods are almost identical, factor out the common hpt{37x|3x2n}_set_mode() function to be called by both of them, the same as in 'pata_hpt366' driver. This results in ~5% decrease in the 'pata_hpt37x' driver binary size and in ~4% decrease in the 'pata_hpt3x2n' driver binary size (as measured on x86-32).

[Resending with the proper subject. Sorry for the mess. ] This patch is based on the RFC of Stanislaw Gruszka. More specifically it fixes two possible races: - One, described by Stanislaw, may lead to permanent disabling of the Tx queue. This is fixed by adding the smp_wmb() to propagate the BD consumer change towards the memory. - Second may lead to bnx2x_start_xmit() returning NETDEV_TX_BUSY. This is fixed by taking a tx_lock() before rechecking the number of available Tx BDs. thanks, vlad Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Vladislav Zolotarov <vladz@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
