2008-05-06pata_atiixp: Don't disableAlan Cox
A couple of distributions (Fedora, Ubuntu) were having weird problems with the ATI IXP series PATA controllers being reported as simplex. At the heart of the problem is that both distros ignored the recommendations to load pata_acpi and ata_generic *AFTER* specific host drivers. The underlying cause however is that if you D3 and then D0 an ATI IXP it helpfully throws away some configuration and won't let you rewrite it. Add checks to ata_generic and pata_acpi to pin ATIIXP devices. Possibly the real answer here is to quirk them and pin them, but right now we can't do that before they've been pcim_enable()'d by a driver. I'm indebted to David Gero for this. His bug report not only reported the problem but identified the cause correctly and he had tested the right values to prove what was going on [If you backport this for 2.6.24 you will need to pull in the 2.6.25 removal of the bogus WARN_ON() in pcim_enagle] Signed-off-by: Alan Cox <alan@redhat.com> Tested-by: David Gero <davidg@havidave.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

sata_inic162x now doesn't use any SFF features. Remove all SFF related stuff. * Mask unsolicited ATA interrupts. This removes our primary source of spurious interrupts and spurious interrupt handling can be tightened up. There's no need to clear ATA interrupts by reading status register either. * Don't dance with IDMA_CTL_ATA_NIEN and simplify accesses to IDMA_CTL. * Inherit from sata_port_ops instead of ata_sff_port_ops. * Don't initialize or use ioaddr.

2008-05-06sata_inic162x: use IDMA for ATAPI commandsTejun Heo
Use IDMA for ATAPI commands. Write and some misc commands time out when executed using ATAPI_PROT_DMA but ATAPI_PROT_PIO works fine. As PIO is driven by DMA too, it doesn't make any noticeable difference for native SATA devices. inic_check_atapi_dma() is implemented to force PIO for those ATAPI commands. After this change, sata_inic162x issues all commands using IDMA. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-06sata_inic162x: use IDMA for non DMA ATA commandsTejun Heo
Use IDMA for PIO and non-data commands. This allows sata_inic162x to safely drive LBA48 devices. Kill inic_dev_config() which contains code to reject LBA48 devices.

2008-05-06sata_inic162x: use IDMA for ATA_PROT_DMATejun Heo
The modified driver on initio site has enough clue on how to use IDMA. Use IDMA for ATA_PROT_DMA. * LBA48 now works as long as it uses DMA (LBA48 devices still aren't allowed as it can destroy data if PIO is used for any reason). * No need to mask IRQs for read DMAs as IDMA_DONE is properly raised after transfer to memory is actually completed. There will be some spurious interrupts but host_intr will handle it correctly and manipulating port IRQ mask interacts badly with the other port for some reason, so command type dependent port IRQ masking is not used anymore.

2008-05-06sata_inic162x: update TF read handlingTejun Heo
inic162x can't reliably read back TF or at least we don't know how to do it yet. The only values which seem reliable are status and error. This patch updates access to TF. * implement inic_tf_read() which reads the TF area in mmio area * implement custom inic_qc_fill_rtf() which only returns true if status indicates device error. it'll be returning bogus addresses for device errors but it'll be able to report why it failed at least. * implement custom inic_check_ready() and use ata_wait_after_reset() instead of the SFF version. * use inic_tf_read() for classification. This is not perfect but it fixes hotplug detection failure and at least makes the driver report 0's instead of random garbages while reporting valid status and error for device errors.

2008-05-06sata_mv NCQ-EH for FIS-based switchingMark Lord
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. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-06sata_mv delayed eh handlingMark Lord
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.

2008-05-06sata_mv NCQ and SError fixes for mv_err_intrMark Lord
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.

2008-05-06sata_mv rearrange mv_config_fbsMark Lord

2008-05-06sata_mv new mv_qc_defer methodMark Lord

2008-05-06sata_mv wait for empty+idleMark Lord
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.

2008-05-06libata: improve post-reset device ready testTejun Heo
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>

x86.git testing found the following build failure in latest -git: drivers/built-in.o: In function `nsc_ircc_pnp_probe': nsc-ircc.c:(.text+0xdf1b6): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf1d4): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf1ee): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf237): undefined reference to `pnp_get_resource' nsc-ircc.c:(.text+0xdf24c): undefined reference to `pnp_get_resource' drivers/built-in.o:nsc-ircc.c:(.text+0xdf266): more undefined references to `pnp_get_resource' follow make: *** [.tmp_vmlinux1] Error 1 triggered via this config: http://redhat.com/~mingo/misc/config-Sat_May__3_20_53_13_CEST_2008.bad while generally most users will have PNP enabled, drivers can support non-PNP build mode too - and most drivers implement it. That is typically done by providing a dummy pnp_driver structure that will not probe anything. The fallback routines in the driver will handle this dumber mode of operation too. This patch implements that. I have not tested whether this actually works on real hardware so take care. It does resolve the build bug. [ Another solution that is used by a few drivers is to exclude the driver in the Kconfig if PNP is disabled, via "depends on PNP", but this would limit the availability of the driver needlessly. ] Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David S.

2008-05-04ide: IDE_HFLAG_SERIALIZE_DMA bugfixBartlomiej Zolnierkiewicz
Patch re-ordering could be harmful: commit 1fd1890594bd355a4217f5658a34763e77decee3 Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Date: Sat Apr 26 22:25:24 2008 +0200 ide: add IDE_HFLAG_SERIALIZE_DMA host flag ... is buggy because ->init_dma method / ide_hwif_setup_dma() is called before IDE_HFLAG_SERIALIZE_DMA host flag is checked. Fix it by checking IDE_HFLAG_SERIALIZE[_DMA] after DMA initialization. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-05-04niu: Fix probing regression for maramba on-board chips.David S. Miller
Changeset 7f7c4072ea552f97a0898331322f71986a97299c ("niu: Determine the # of ports from the card's VPD data") caused maramba on-board NIU ports to stop probing properly. The old code had a fallback that would use a num_ports value of 4 if all the probing methods failed, but that was removed. This restores the fallback of 4 ports, to get things working again. Bump driver version and release date. Signed-off-by: David S. Miller <davem@davemloft.net>
