2007-07-09ide: add short cables supportBartlomiej Zolnierkiewicz
This patch allows users to override both host and device side cable detection with "ideX=ata66" kernel parameter. Thanks to this it should be now possible to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable instead of 80-pin one. Next patches add automatic detection of some systems using short cables. Changes: * Rename hwif->udma_four to hwif->cbl and make it u8. * Convert all existing users accordingly (use ATA_CBL_* defines while at it). * Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three(). * Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

Currently when system which have HPA require HPA to be detected and disabled upon resume from RAM or disk. The current IDE drivers do not do this nor does libata (obviously it since it doesn't support HPA yet). I have implemented this into the current IDE drivers and it has been tested by many others since 7/15/2006 in bug number 6840: http://bugzilla.kernel.org/show_bug.cgi?id=6840 and it has been confirmed to work fine with no problems. bart: added drv != NULL check to generic_ide_suspend() From: Lee Trager <lt73@cs.drexel.edu> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-05-10ide: legacy PCI bus order probing fixesBartlomiej Zolnierkiewicz
IDE PCI host drivers should register themselves with IDE core only when IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI host drivers are also modular) the code has no effect and just complicates the probing. Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when needed and invisible to the user) and covering by #ifdef/#endif the code in question. It turned out that "ide=reverse" was silently accepted but did nothing in case when IDE driver was modular, this is fixed now. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-03-26ide: fix locking for manual DMA enable/disable ("hdparm -d")Bartlomiej Zolnierkiewicz
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).

2007-03-17ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config optionsBartlomiej Zolnierkiewicz
All modern distributions have been setting these options to "y" for ages. (additionally "n" cases have been obsoleted for few years). Therefore use DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used to enable DMA support and which were forced to PIO mode by "ide: don't allow DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no functionality loss because "ide=nodma" kernel option is still available.

2007-02-07ACPI support for IDE devicesHannes Reinecke
This patch implements ACPI integration for generic IDE devices. The ACPI spec mandates that some methods are called during suspend and resume. And consequently there most modern Laptops cannot resume properly without it. According to the spec, we should call '_GTM' (Get Timing) upon suspend to store the current IDE adapter settings. Upon resume we should call '_STM' (Set Timing) to initialize the adapter with the stored settings; afterwards '_GTF' (Get Taskfile) should be called which returns a buffer with some IDE initialisation commands. Those commands should be passed to the drive. There are two module params which control the behaviour of this patch: 'ide=noacpi' Do not call any ACPI methods (Disables any ACPI method calls) 'ide=acpigtf' Enable execution of _GTF methods upon resume. Has no effect if 'ide=noacpi' is set. 'ide=acpionboot' Enable execution of ACPI methods during boot. This might be required on some machines if 'ide=acpigtf' is selected as some machines modify the _GTF information depending on the drive identification passed down with _STM.

2006-06-23[PATCH] m68k: completely initialize hw_regs_t in ide_setup_portsRoman Zippel
ide_setup_ports does not completely initialize the hw_regs_t structure which can cause random failures, as the structure is often on the stack. None of the callers expect a partially initialized structure, i.e. none of them do any setup of their own before calling ide_setup_ports().

2006-03-25[PATCH] ide: fix section mismatch warningSam Ravnborg
In latest -mm ide-code.o gave a number of warnings like the following: WARNING: drivers/ide/ide-core.o - Section mismatch: reference to \ .init.text: from .text between 'init_module' (at offset 0x1f97) and \ 'cleanup_module' The warning was caused by init_module() calling parse_option() and ide_init() both declared __init. Declaring init_module() __init fixes the warnings.

2006-02-03[PATCH] stop CompactFlash devices being marked as removableRichard Purdie
This patch stops CompactFlash devices being marked as removable. They are not removable (as defined by Linux) as the media and device are inseparable. When a card is removed, the whole device is removed from the system and never sits in a media-less state. This stops some nasty udev device creation/destruction loops. Further, once this change is made, there is no need for ide to can be removed from ide_drive_t.

The patch changes semaphores that are initialized as locked to complete(). Source: MontaVista Software, Inc. Modified-by: Steven Rostedt <rostedt@goodmis.org> The following patch is from Montavista.
