* [PATCH] pcmcia: remove prod_id indirectionDominik Brodowski2006-12-04
| | | | | | | | | As we read out the product information strings (VERS_1) from the PCMCIA device in the PCMCIA core, and device drivers can access those reliably in struct pcmcia_device's fields prod_id[], remove additional product information string detection logic from PCMCIA device drivers.

* [PATCH] pcmcia: multifunction card handling fixesDominik Brodowski2006-12-04
| | | | | | | | | | | | | | | | | | s->functions needs to be initialized earlier, for the "let's see how high it increases" approach means that pcmcia_request_irq() (which makes use of this value) is confused, and might request an exclusive IRQ first even though it is not supposed to. Also, a CIS override autoloaded using the firmware loader may allow for the use of more or less functions in a multifunction card. Therefore, we may need to schedule a call to add this second function later on, or simply remove the other function (it's always the first -valid- function which reaches this codepath).

| * [PATCH] sata_promise: PHYMODE4 fixupMikael Pettersson2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to fix up the PHYMODE4 "align timing" register value on second-generation Promise SATA chips. Failure to correct this value on non-x86 machines makes drive detection prone to failure due to timeouts. (I've observed about 50% detection failure rates on SPARC64.) The HW boots with a bad value in this register, but on x86 machines the Promise BIOS corrects it to the value recommended by the manual, so most people have been unaffected by this issue. After developing the patch I checked Promise's SATAII driver, and discovered that it also corrects PHYMODE4 just like this patch does. This patch depends on the sata_promise SATAII updates patch I sent recently. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: always use polling IDENTIFYTejun Heo2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was introduced. This has caused a lot of problems including device misdetection and phantom device. ATA_FLAG_DETECT_POLLING was added recently to selectively use polling IDENTIFY on problemetic drivers but many controllers and devices are affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING for each such case is diffcult and not very rewarding. This patch makes libata always use polling IDENTIFY. This is consistent with libata's original behavior and drivers/ide's behavior.

| * [PATCH] ahci: do not powerdown during initializationTejun Heo2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ahci_init_controller() calls ahci_deinit_port() to make sure the controller is stopped before initializing the controller. In turn, ahci_deinit_port() invokes ahci_power_down() to power down the port. If the controller supports slumber mode, the link is put into it. Unfortunately, some devices don't implement link powersaving mode properly and show erratic behavior after link is put into slumber mode. For example, HL-DT-ST DVD-RAM GSA-H30N completely locks up on slumber transition and can only be recovered with the *REAL* hard reset - power removal and reapply. Note that this makes the first probing reset different from all others. If the above dvd-ram is hotplugged after ahci is initialized, no problem occurs because ahci is already fully initialized with phy powered up. So, this might also be the reason for other weird AHCI initial probing abnormalities. This patch moves power up/down out of port init/deinit and call them only when needed. Power down is now called only when suspending. As system suspend usually involves powering down 12v for storage devices, this shouldn't cause problem even if the attached device doesn't support slumber mode. However, in partial power management and suspend failure cases, devices might lock up after suspend attempt. I thought about removing transition to slumber mode altogether but ahci spec mandates it before HBA D3 state transition. Blacklisting such devices might be the solution.

| * [PATCH] libata: make sure IRQ is cleared after ata_bmdma_freeze()Tejun Heo2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that BMDMA status is recorded in irq handler. ata_bmdma_freeze() is free to manipulate host status. Under certain circumstances, some controllers (ICH7 in enhanced mode w/ IRQ shared) raise IRQ when CTL register is written to and ATA_NIEN doesn't mask it. This patch makes ata_bmdma_freeze() clear all pending IRQs after freezing a port. This change makes explicit clearing in ata_device_add() unnecessary and thus kills it. The removed code was SFF-specific and was in the wrong place. Note that ->freeze() handler is always called under ap->lock held and irq disabled. Even if CTL manipulation causes stuck IRQ, it's cleared immediately. This should be safe (enough) even in SMP environment. More correct solution is to mask the IRQ from IRQ controller but that would be an overkill. Signed-off-by: Tejun Heo <htejun@gmail.com>

| * [PATCH] libata: set IRQF_SHARED for legacy PCI IDE IRQsTejun Heo2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are machines out there which share legacy PCI IDE IRQs w/ other devices. libata SFF interrupt/HSM code is ready for shared IRQ and has been setting IRQF_SHARED for devices in native PCI mode. Device in legacy mode is still a PCI device and thus supposedly uses active-low level triggered IRQ. Machines with such setup should be quite rare and w/o this flag libata is likely to fail loading and render the system unuseable. Also, IDE driver has been setting IRQF_SHARED for devices in legacy mode for a looooong time. Signed-off-by: Tejun Heo <htejun@gmail.com>
| * [PATCH] libata: remove unused HSM_ST_UNKNOWNTejun Heo2006-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HSM_ST_UNKNOWN is not used anywhere. Its value is zero and supposed to serve sanity check purpose but HSM_ST_IDLE is used for that purpose. This unused state causes confusion. After a port is initialized but before the first command is executed, the idle hsm state is UNKNOWN. However, once a command has completed, the idle hsm state is IDLE. This defeats sanity check in ata_pio_task() for the first command. This patch removes HSM_ST_UNKNOWN and consequently make HSM_ST_IDLE the default state. Signed-off-by: Tejun Heo <htejun@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv with ATAPI devices on controllers running in ADMA mode. Some of the logic in the nv_adma_bmdma_* functions was inverted causing a bunch of warnings and caused those functions not to work properly. Also, when an ATAPI device is connected, we need to use the legacy DMA engine. The code now disables the PCI configuration register bits for ADMA so that this works, and ensures that no ATAPI DMA commands go through until this is done.
