* sata_mv use hweight16() for bit counting (V2)Mark Lord2008-05-061-12/+6
| | | | | | | | | | Some tidying as suggested by Grant Grundler. Nuke local bit-counting function from sata_mv in favour of using hweight16(). Also add a short explanation for the 15msec timeout used when waiting for empty/idle. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sata_mv NCQ-EH for FIS-based switchingMark Lord2008-05-061-0/+165
| | | | | | | | | | | | | | | | | | | | | | | | Convert sata_mv's EH for FIS-based switching (FBS) over to the sequence recommended by Marvell. This enables us to catch/analyze multiple failed links on a port-multiplier when using NCQ. To do this, we clear the ERR_DEV bit in the EDMA Halt-Conditions register, so that the EDMA engine doesn't self-disable on the first NCQ error. Our EH code sets the MV_PP_FLAG_DELAYED_EH flag to prevent new commands being queued while we await completion of all outstanding NCQ commands on all links of the failed PM. The SATA Test Control register tells us which links have failed, so we must only wait for any other active links to finish up before we stop the EDMA and run the .error_handler afterward. The patch also includes skeleton code for handling of non-NCQ FBS operation. This is more for documentation purposes right now, as that mode is not yet enabled in sata_mv.

* sata_mv delayed eh handlingMark Lord2008-05-061-1/+37
| | | | | | | | | | | | | | | | | | | | | | | Introduce a new "delayed error handling" mechanism in sata_mv, to enable us to eventually deal with multiple simultaneous NCQ failures on a single host link when a PM is present. This involves a port flag (MV_PP_FLAG_DELAYED_EH) to prevent new commands being queued, and a pmp bitmap to indicate which pmp links had NCQ errors. The new mv_pmp_error_handler() uses those values to invoke ata_eh_analyze_ncq_error() on each failed link, prior to freezing the port and passing control to sata_pmp_error_handler(). This is based upon a strategy suggested by Tejun. For now, we just implement the delayed mechanism. The next patch in this series will add the multiple-NCQ EH code to take advantage of it.

* sata_mv NCQ and SError fixes for mv_err_intrMark Lord2008-05-061-21/+43
| | | | | | | | | | | | | | | | | | Sigh. Undo some earlier changes to mv_port_intr(), so that we now read/clear SError again in all cases. Arrange the top of the function to be as close as possible to what we need for a later update (in this series) for ERR_DEV handling. Fix things so that libata-eh can attempt a READ_LOG_EXT_10H in response to a failed NCQ command, by just doing a local mv_eh_freeze() rather than ata_port_freeze(). This will now fully handle NCQ errors much of the time, but more fixes are needed for FBS/PMP, and for certain chip errata.

| | | | | | | | | | | The EDMA engine cannot tolerate a mix of NCQ/non-NCQ commands, and cannot be used for PIO at all. So we need to prevent libata from trying to feed us such mixtures.

* sata_mv wait for empty+idleMark Lord2008-05-061-0/+20
| | | | | | | | | | | | | | | | When performing EH, it is recommended to wait for the EDMA engine to empty out requests-in-progress before disabling EDMA. Introduce code to poll the EDMA_STATUS register for idle/empty bits before disabling EDMA. For non-EH operation, this will normally exit without delay, other than the register read. A later series of patches may focus on eliminating this and various other register reads (when possible) throughout the driver, but for now we're focussing on solid reliablity.

* libata: improve post-reset device ready testTejun Heo2008-05-062-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that the device isn't ready yet. It looks like they use 0xff if device presence is detected but connection isn't established. 0x77 or 0x7f after connection is established and use the value from signature FIS after receiving it. This patch implements ata_check_ready(), which takes TF status value and determines whether the port is ready or not considering the above and other conditions, and use it in @check_ready() functions. This is safe as both 0x77 and 0x7f aren't valid ready status value even though they have BSY bit cleared. This fixes hot plug detection failures which can be triggered with certain drives if they aren't already spun up when the data connector is hot plugged. Tested on sil, sil24, ahci (jmb/ich), piix and inic162x combined with eight drives from all major vendors. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| * IB/ipoib: Fix transmit queue stalling foreverEli Cohen2008-05-013-6/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f56bcd80 ("IPoIB: Use separate CQ for UD send completions") introduced a bug where the transmit queue could get stopped and never woken up. The problem is that send completions are only polled at the end of the xmit function, so if the send queue fills up and the xmit path stops the queue, then there is no way for send completions to ever get polled, and so the transmit queue stays stopped forever. Fix this by arming the send CQ just before posting the last send request that fills the send queue. Then, when the completion event handler is called, drain the send CQ. Since it is possible that not enough send completions are in the CQ, verify that the the net queue has been woken up after draining the send CQ, and if not arm a timer and drain again at the timer function.

| * IB/mlx4: Fix off-by-one errors in calls to mlx4_ib_free_cq_buf()Roland Dreier2008-05-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I merged bbf8eed1 ("IB/mlx4: Add support for resizing CQs") I changed things around so that mlx4_ib_alloc_cq_buf() and mlx4_ib_free_cq_buf() were used everywhere they could be. However, I screwed up the number of entries passed into mlx4_ib_alloc_cq_buf() in a couple places -- the function bumps the number of entries internally, so the caller shouldn't add 1 as well. Passing a too-big value for the number of entries to mlx4_ib_free_cq_buf() can cause the cleanup to go off the end of an array and corrupt allocator state in interesting ways.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds init/exit function callbacks to pda_power, to provide a place where the platform code can request/free GPIOs that it wants to use in the is_ac_online, is_usb_online and set_charge functions.

The jumbo rx buffer page size is now configurable and set to the proper PAGE_SIZE. Before, it was assumed to be always 4K. 2. Driver sometimes would crash when receiving jumbo packets mixed with firmware management packets. This was caused by the old firmware DMA'ing to the wrong address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should zero out the context memory for 5709 before each reset. When we resume after suspend for example, the memory may not be zero and the chip may not function correctly.

As a result, the GMII/MII MAC mode does not get setup properly. To fix this problem, we add an initial poll of the link state after chip reset. With this change, the setting of the initial carrier state in the init code can be eliminated.

This feature is implemented in firmware and is largely transparent to the driver, except... It turns out that the UMP firmware needs to know the current status of the link. Because the firmware cannot touch the PHY registers while the driver is in control of the device, it needs the driver to report link status changes through an additional handshaking mechanism. Without this handshake, it has been observed in the field that the UMP firmware will not operate correctly. This patch implements the new handshake with the UMP firmware. Since the handshake uses the same mechanism ASF heartbeats use, code was added to detect and wait for completion of a pending previous event.
