| * [libata] mark certain hardware (or drivers) with a no-atapi flagJeff Garzik2005-12-131-1/+2
| | | | | | | | | | | | | | | | | | | | Some hardware does not support the PACKET command at all. Other hardware supports ATAPI, but the driver does something nasty such as calling BUG() when an ATAPI command is issued. For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI. Initial version contributed by Ben Collins.
* | [PATCH] libata: move err_mask to ata_queued_cmdAlbert Lee2005-12-061-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | - remove err_mask from the parameter list of the complete functions - move err_mask to ata_queued_cmd - initialize qc->err_mask when needed - for each function call to ata_qc_complete(), replace the err_mask parameter with qc->err_mask.

|/ | | | | | | | | | | Hi, the patch below marks several libata (and libata-driver) structures const so that they end up in the .rodata segment and don't false-share cachelines with things that get dirtied often.

* [libata sata_mv] handle lack of hardware nIEN supportJeff Garzik2005-11-171-1/+6
| | | | | | | | | | | Handle errata (it was unintentional on this h/w, whereas its intentional on others) whereby the nIEN bit in Device Control is ignored, leading to a situation where a hardware interrupt completes the qc before the polling code has a chance to. This will get fixed The Right Way(tm) once Albert Lee's irq-pio branch is merged, as the more natural PIO method on this hardware is interrupt-driven.
* [libata sata_mv] SATA probe, DMA boundary fixesJeff Garzik2005-11-171-18/+70
| | | | | | | | - DMA boundary was being handled incorrectly. Copied the code from ata_fill_sg(), since Marvell has the same DMA boundary needs. (we can't use ata_fill_sg directly since we have different hardware descriptors) - cleaned up the SATA phy reset code, to deal with various errata

* [libata sata_mv] mv_hw_ops for hardware families; new errataJeff Garzik2005-11-121-138/+158

| | | | | | | Use ata_pad_{alloc,free} in two drivers, to factor out common code. Add ata_pad_{alloc,free} to two other drivers, which needed the padding but had not been updated.

| * [libata] use dev_printk() throughout driversJeff Garzik2005-10-301-6/+6
| | | | | | | | | | | | A few drivers were not following the standard meme of printing out their driver name and version at module load time; this is fixed as well.

| * [libata] change ata_qc_complete() to take error mask as second argJeff Garzik2005-10-301-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

* [PATCH] libata: Marvell SATA support (DMA mode) (resend: v0.22)Brett Russ2005-10-031-189/+749
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is my libata compatible low level driver for the Marvell SATA family. Currently it runs in DMA mode on a 6081 chip. The 5xxx series parts are not yet DMA capable in this driver because the registers have differences that haven't been accounted for yet. Basically, I'm focused on the 6xxx series right now. I apologize for those seeing problems on the 5xxx series, I've not had a chance to look at those problems yet. For those curious, the previous bug causing the SCSI timeout and subsequent panics was caused by an improper clear of hc_irq_cause in mv_host_intr(). This version is running well in my environment (6081 chips, with/without SW raid1) and is showing equal or better performance compared to the Marvell driver (mv_sata) in my initial tests (timed dd's of reads/writes to/from memory/disk). I still need to look at the causes of occasional problems such as this: ata11: translating stat 0x35 err 0x00 to sense ata11: status=0x35 { DeviceFault SeekComplete CorrectedError Error } SCSI error : <10 0 0 0> return code = 0x8000002 Current sda: sense key Hardware Error end_request: I/O error, dev sda, sector 3155010 and this, seen at init time: ATA: abnormal status 0x80 on port 0xE093911C but they aren't showstoppers.

* [PATCH] libata: Marvell SATA support (PIO mode)Brett Russ2005-09-071-0/+827
This is my libata compatible low level driver for the Marvell SATA family. Currently it successfully runs in PIO mode on a 6081 chip. EDMA support is in the works and should be done shortly. Review, testing (especially on other flavors of Marvell), comments welcome. Signed-off-by: Brett Russ <russb@emc.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
