* ide: use correct IDE error recoverySuleiman Souhlal2007-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set. This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not busy) and really hoses up some drives (modern drives will not be able to recover using this error handling). The correct thing to do is issue a SRST followed by a SET FEATURES command. This is what Western Digital recommends for error recovery and what Western Digital says Windows does.  It also does not violate the ATA spec as far as I can tell. Bart: * port the patch over the current tree * undo the recalibration code removal * send SET FEATURES command after checking for good drive status * don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK} type because we need to send SET FEATURES before handling any requests * some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before other commands (except IDENTIFY) so send SET FEATURES only if there are no pending drive->special requests * update comments and patch description * any bugs introduced by this patch are mine and not Suleiman's :-) Signed-off-by: Suleiman Souhlal <suleiman@google.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* pdc202xx_new: Enable ATAPI DMAAlbert Lee2007-03-26
| | | | | | | | | | | | | | [ bart: the ressurection of 2 years old patch which slipped thru the cracks (thanks to Sergei Shtylyov for finding it) ] These is the patch to turn on pdc202xx_new for ATAPI DMA. When testing, it works fine without the (request_bufflen % 256) workaround as needed in libata. ide-scsi filters out (pc->request_transfer % 1024) and use PIO, so the pdc202xx ATAPI DMA problem is avoid. Both ide-cd and ide-scsi won't hit the ATAPI DMA problem on pdc202xx_new. Signed-off-by: Albert Lee <albertcc@tw.ibm.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: cosmetic adaption of drivers/ide/Kconfig concerning SATAPatrick Ringl2007-03-26
| | | | | | | | | | Since especially Serial ATA has it's own menu point now, I guess we can change the description of the deprecated SATA driver as well, since the new libATA subsystem is not configured through a SCSI low-level driver anymore, but has it's own menu point.

* ide: fix locking for manual DMA enable/disable ("hdparm -d")Bartlomiej Zolnierkiewicz2007-03-26
| | | | | | | | | | | | | | | | | Since hwif->ide_dma_check and hwif->ide_dma_on never queue any commands (ide_config_drive_speed() sets transfer mode using polling and has no error recovery) we are safe with setting hwgroup->busy for the time while DMA setting for a drive is changed (so it won't race against I/O commands in fly). I audited briefly all ->ide_dma_check/->ide_dma_on/->tuneproc/->speedproc implementations and they all look OK wrt to this change. This patch finally allowed me to close kernel bugzilla bug #8169 (once again thanks to Patrick Horn for reporting the issue & testing patches).

* ide: revert "ide: fix drive side 80c cable check, take 2" for nowBartlomiej Zolnierkiewicz2007-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | "ide: fix drive side 80c cable check, take 2" patch from Tejun Heo (commit fab59375b9543f84d1714f7dd00f5d11e531bd3e) fixed 80c bit test (bit13 of word93) but we also need to fix master/slave IDENTIFY order (slave device should be probed first in order to make it release PDIAG- signal) and we should also check for pre-ATA3 slave devices (which may not release PDIAG- signal). [ Unfortunately the fact that IDE driver doesn't reset devices itself helps only a bit as it seems that some BIOS-es reset ATA devices after programming the chipset, some BIOS-es can be set to not probe/configure selected devices, there may be no BIOS in case of add-on cards etc. ] Since we are quite late in the release cycle and the required changes will affect a lot of systems just revert the fix for now. [ Please also see libata commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c. ] Thanks goes out to Fernando Mitio Yamada for reporting the problem and patiently testing patches.

This problem was fixed by adding one bit to the field used for the offset, and subtracting one bit from the space used for the id. (2) In MANUALWLAN mode, the IRQ XMIT errors are generated. The cause of these errors has not yet been located. Any suggestions on debugging this problem would be greatly appreciated.

* | | [PATCH] i386: add command line option "local_apic_timer_c2_ok"Thomas Gleixner2007-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turned out that it is almost impossible to trust ACPI, BIOS & Co. regarding the C states. This was the reason to switch the local apic timer off in C2 state already. OTOH there are sane and well behaving systems, which get punished by that decision. Allow the user to confirm that the local apic timer is trustworthy in C2 state. This keeps the default behaviour on the safe side.

According to Intel only specific Intel models (Banias/Dothan) are broken in respect of not waking up from C2 with lapic. However, I am not sure about the naming of the parameter and how it could/should get integrated into the dyntick part (CONFIG_GENERIC_CLOCKEVENTS). There, a more fine grained check (TSC still running?, ..) is needed? Does this make sense (always use CLOCK_EVT_NOTIFY_BROADCAST_ON, but use OFF if forced by use_ipi=0: clockevents_notify(use_ipi ? CLOCK_EVT_NOTIFY_BROADCAST_ON : CLOCK_EVT_NOTIFY_BROADCAST_OFF, &pr->id); Signed-off-by: Thomas Renninger <trenn@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

However, it caused an immediate S3 resume on the HP nx6125. Apparently, on the HP, a GPE was getting re-enabled after the prepare, but before the enter. Close that window by restoring the GPE disable on enter. This is redundant in most cases, but closes this window, where S3 and S4 paths differ.
