* libata: fix assigned IRQ reportingTejun Heo2007-07-03
| | | | | | | | | | | | | | host->irq and host->irq2 should be set before ata_host_register() for IRQ reporting to work. Move up host->irq assignment in ata_host_activate() and add it to ata_pci_init_one() native path and pata_cs5520. The port info printing in ata_host_register() doesn't fit all the different controllers. It should probably be moved out to LLDs with some helpers in the future.

* libata: PATA-mode fixes for sis_sataUwe Koziolek2007-07-02
| | | | | | | | | | | | | | | | Changed PATA handler for PATA-ports used by sata_sis. This patch was originally submitted by Jeff Garzik. Added PCI-ID 1180 for SiS966 Controller in pata_sis. The 1180 mode is fully compatible to other SiS PATA-controller. The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis. 1183 is not working if simply added to pata_sis. This handling fixes issues with SiS968. Signed-off-by: Uwe Koziolek <uwe.koziolek@gmx.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* libata: pata_pdc2027x PLL input clock fixAlbert Lee2007-07-02
| | | | | | | | | | | | | | | Recently the PLL input clock of pata_pdc2027x is sometimes detected higer than expected (e.g. 20.027 MHz compared to 16.714 MHz). It seems sometimes the mdelay() function is not as precise as it used to be. Per Alan's advice, HT or power management might affect the precision of mdelay(). This patch calls gettimeofday() to mesure the time elapsed and calculate the PLL input clock accordingly.

* libata: kill ATA_HORKAGE_DMA_RW_ONLYTejun Heo2007-06-27
| | | | | | | | | | ATA_HORKAGE_DMA_RW_ONLY for TORiSAN is verified to be subset of using DMA for ATAPI commands which aren't aligned to 16 bytes.

* libata: use PIO for non-16 byte aligned ATAPI commandsTejun Heo2007-06-27
| | | | | | | | | | | | | | | | | | | | | | | The IDE driver used DMA for ATAPI commands if READ/WRITE command is multiple of sector size or sg command is multiple of 16 bytes. For libata, READ/WRITE sector alignment is guaranteed by the high level driver (sr), so we only have to worry about the 16 byte alignment. This patch makes ata_check_atapi_dma() always request PIO for all data transfer commands which are not multiple of 16 bytes.

* pata_it821x: (partially) fix DMA in RAID modeBartlomiej Zolnierkiewicz2007-06-20
| | | | | | | | | | | | | | | | | | | | Code intended to check DMA status was checking DMA command register. Moreover firmware seems to "forget" to set DMA capable bit for the slave device (at least in RAID mode but without ITE RAID volumes) so check device ID for DMA capable bit when deciding whether to use DMA and remove DMA status check completely. Thanks to Pavol Simo for the bugreport and testing the initial fix. This change unfortunately still doesn't fix DMA in RAID mode (which works fine with IDE it821x) but Alan is working on the missing pieces (pata_it821x vs libata EH issues).

* libata: limit post SRST nsect/lbal wait to ~100msTejun Heo2007-06-11
| | | | | | | | | | | | | | | | | | | After SRST, libata used to wait for nsect/lbal to be set to 1/1 for the slave device. However, some ATAPI devices don't set nsect/lbal after SRST and the wait itself isn't too useful as we're gonna wait for !BSY right after that anyway. Before reset-seq update, nsect/lbal wait failure used to be ignored and caused 30sec delay during detection. After reset-seq, all timeouts are considered error conditions making libata fail to detect such ATAPI devices. This patch limits nsect/lbal wait to around 100ms. This should give acceptable behavior to such ATAPI devices while not disturbing the heavily used code path too much.

* libata-core/sff: Fix multiple assumptions about DMAAlan Cox2007-06-09
| | | | | | | | | | | | | | | The ata IRQ ack functions are only used when debugging. Unfortunately almost every controller that calls them can cause crashes in some configurations as there are missing checks for bmdma presence. In addition ata_port_start insists of installing DMA buffers and pad buffers for controllers regardless. The SFF controllers actually need to make that decision dynamically at controller setup time and all need the same helper - so we add ata_sff_port_start. Future patches will switch the SFF drivers to use this. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* sata_promise: use TF interface for polling NODATA commandsTejun Heo2007-06-08
| | | | | | | | | | | | | | | | | | | | | | sata_promise uses two different command modes - packet and TF. Packet mode is intelligent low-overhead mode while TF is the same old taskfile interface. As with other advanced interface (ahci/sil24), ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are issued using TF interface in polling mode, so pdc_interrupt() considers interrupts spurious if ATA_TFLAG_POLLING is set. This is broken for polling NODATA commands because command is issued using packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING. Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued using TF interface if ATA_TFLAG_POLLING is set. This patch fixes detection failure introduced by polling SETXFERMODE.

* libata: always use polling SETXFERTejun Heo2007-06-04
| | | | | | | | | | | | | | | | | | | | | | Several people have reported LITE-ON LTR-48246S detection failed because SETXFER fails. It seems the device raises IRQ too early after SETXFER. This is controller independent. The same problem has been reported for different controllers. So, now we have pata_via where the controller raises IRQ before it's ready after SETXFER and a device which does similar thing. This patch makes libata always execute SETXFER via polling. As this only happens during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is also moved from issue hot path to ata_dev_set_xfermode() - the only place where SETXFER can be issued. Note that ATA_TFLAG_POLLING applies only to drivers which implement SFF TF interface and use libata HSM. More advanced controllers ignore the flag. This doesn't matter for this fix as SFF TF controllers are the problematic ones. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
