* ide: remove no longer needed BUG_ON()-s from init_irq()Bartlomiej Zolnierkiewicz2008-10-10
| | | | | | | | init_irq() is now called only during initial host registration so these BUG_ON()-s are no loner needed (+ the last one was done too late anyway). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: enhance ide_busy_sleep()Bartlomiej Zolnierkiewicz2008-10-10
| | | | | | | | | | | | | * Make ide_busy_sleep() take timeout value as a parameter and also allow use of AltStatus Register if requested with altstatus parameter. Update existing users accordingly. * Convert ide_driveid_update() and actual_try_to_identify() to use ide_busy_sleep(). There should be no functional changes caused by this patch.

* ide: make drive->id an union (take 2)Bartlomiej Zolnierkiewicz2008-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free. While at it: - Add missing KERN_CONTs in it821x.c. - Use ATA_ID_WORDS and ATA_ID_*_LEN defines. - Remove unnecessary checks for drive->id. - s/drive_table/table/ in ide_in_drive_list(). - Cleanup ide_config_drive_speed() a bit. - s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave(). v2: Fix typo in drivers/ide/ppc/pmac.c.

However, that was removed (by me!) years ago, so mthca can just use pci_request_regions() and pci_release_regions() instead of its own much more complicated code that avoids requesting the MSI-X tables.

| | | | | * | IPoIB: Use netif_tx_lock() and get rid of private tx_lock, LLTXRoland Dreier2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, IPoIB is an LLTX driver that uses its own IRQ-disabling tx_lock. Not only do we want to get rid of LLTX, this actually causes problems because of the skb_orphan() done with this tx_lock held: some skb destructors expect to be run with interrupts enabled. The simplest fix for this is to get rid of the driver-private tx_lock and stop using LLTX. We kill off priv->tx_lock and use netif_tx_lock[_bh]() instead; the patch to do this is a tiny bit tricky because we need to update places that take priv->lock inside the tx_lock to disable IRQs, rather than relying on tx_lock having already disabled IRQs. Also, there are a couple of places where we need to disable BHs to make sure we have a consistent context to call netif_tx_lock() (since we no longer can use _irqsave() variants), and we also have to change ipoib_send_comp_handler() to call drain_tx_cq() through a timer rather than directly, because ipoib_send_comp_handler() runs in interrupt context and drain_tx_cq() must run in BH context so it can call netif_tx_lock().

| | | | | * | IPoIB: Fix crash when path record fails after path flushRoland Dreier2008-09-25

This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

| | | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a QP goes into error state, it is required that CQ entries with a flush error status are delivered to the application for any outstanding work requests. eHCA does not do this in hardware, so this patch adds software flush CQE generation to the ehca driver. Whenever a QP gets into error state, it is added to the QP error list of its respective CQ. If the error QP list of a CQ is not empty, poll_cq() generates flush CQEs before polling the actual CQ.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running ibv_devinfo, the active_mtu returned is garbage. This is due to the field not being populated in the query_port function in the driver. The patch below populates the active_mtu field with a MTU of 2k. It also zeros the struct, so that any new additions to it will return 0.
