2006-08-24[PATCH] sata_via: use old SCR access pattern on vt6420Tejun Heo
vt6420 has super-fragile SCR registers which can hang the whole machine if accessed with the wrong timings. This patch makes sata_via use SCR registers only during probing and with the same timings as before (pre new EH), which is proven to work.

2006-08-24[PATCH] ata_piix: implement force_pcs module parameterTejun Heo
This patch implements force_pcs module parameter for ata_piix. If 1, PCS is ignored, 2 honored. As there seem to be quite a few ICHs w/ impaired PCS, this option will be useful for cases where the default setting doesn't work.

2006-08-24[PATCH] ata_piix: ignore PCS on ICH5Tejun Heo
There have been a number of reports regarding some ICH5s failing to detect devices since the PCS handling update. Analysis shows that these problems are caused by bogus PCS values from those controllers. Before the PCS update, the driver didn't honor PCS regs exactly and probed them in many cases PCS reports no device. Now that PCS is honored exactly, these hardware problems are visible. This patch makes ICH5 ignore PCS. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-08-22[PATCH] ata_piix: fix ghost device probing by honoring PCS present bitsTejun Heo
Move out PCS handling from piix_sata_prereset() into piix_sata_present_mask() and use it from newly implemented piix_sata_softreset(). Class codes for devices which are indicated to be absent by PCS are cleared to ATA_DEV_NONE. This fixes ghost device problem reported on ICH6 and 7. This patch moves PCS handling from prereset to softreset, which makes two behavior changes. * perform softreset even when PCS indicates no device * PCS handling is repeated before retrying softresets due to reset failures. Both behavior changes are intended and more consistent with how other drivers behave. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-08-17[PPP]: handle kmalloc failures and convert to using kzallocPanagiotis Issaris
The PPP code contains two kmalloc()s followed by memset()s without handling a possible memory allocation failure. (Suggested by Joe Perches). And furthermore, conversions from kmalloc+memset to kzalloc.

2006-08-17[BNX2]: Fix tx race condition.Michael Chan
Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int() similar to the one in tg3 discovered by Herbert Xu: CPU0 CPU1 bnx2_start_xmit() if (tx_ring_full) { tx_lock bnx2_tx() if (!netif_queue_stopped) netif_stop_queue() if (!tx_ring_full) update_tx_ring netif_wake_queue() tx_unlock } Even though tx_ring is updated before the if statement in bnx2_tx_int() in program order, it can be re-ordered by the CPU as shown above. This scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has just freed up the entire tx_ring. The possibility of this happening should be very rare though. The following changes are made, very much identical to the tg3 fix: 1. Add memory barrier to fix the above race condition. 2. Eliminate the private tx_lock altogether and rely solely on netif_tx_lock. This eliminates one spinlock in bnx2_start_xmit() when the ring is full. 3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling netif_wake_queue(). 4. Add memory barrier to bnx2_tx_avail(). 5. Add bp->tx_wake_thresh which is set to half the tx ring size. 6. Check for the full wake queue condition before getting netif_tx_lock in tg3_tx(). This reduces the number of unnecessary spinlocks when the tx ring is full in a steady-state condition.

2006-08-09[PATCH] libata: clear sdev->locked on door lock failureTejun Heo
SCSI EH locks door if sdev->locked is set. Sometimes door lock command fails continuously (e.g. when medium is not present) and as libata uses EH to acquire sense data, this easily creates a loop where a failed lock door invokes EH and EH issues lock door on completion. This patch clears sdev->locked on door lock failure to break this loop. This problem has been spotted and diagnosed by Unicorn Chang <uchang@tw.ibm.com>.
