The PDC202xx older devices do not support ATAPI DMA via the usual interfaces. What documentation I have isn't sufficient to support DMA and it isn't clear if the Windows drivers do this or it is possible at all. (Neither do the drivers/ide old drivers) So turn it ATAPI DMA off, these are disk optimised controllers.

Turns out distros always enabled burst mode and it is pretty essential so do the same. Also sort out the post DMA mode restore properly. My 20263 card now seems happy but needs some four drive tests done yet (when I've persuaded the kernel not to hang in the edd boot code if I plug them in ..)

I've been doing an audit of this driver to try and find out why we have problems with some Clevo boxes that use it. Didn't get anywhere other than to discover all the bug reporters I have use vmware, which may or may not be chance. In the process however I did find out our MWDMA2 performance was a bit low and code review showed the MWDMA0/2 timings are reversed due to a thinko in the table ordering Signed-off-by: NAlan Cox <alan@redhat.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

* ->irq_ack() is redundant to what the irq handler already performs... chk-status + irq-clear. Furthermore, it is only called in one place, when screaming-irq-debugging is enabled, so we don't want to bother with a hook just for that. * ata_dummy_irq_on() is only ever used in drivers that have no callpath reaching ->irq_on(). Remove .irq_on hook from those drivers, and the now-unused ata_dummy_irq_on() Signed-off-by: NJeff Garzik <jeff@garzik.org>

The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers. It's simple enough. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Reimplement suspend/resume support using sdev->manage_start_stop. * Device suspend/resume is now SCSI layer's responsibility and the code is simplified a lot. * DPM is dropped. This also simplifies code a lot. Suspend/resume status is port-wide now. * ata_scsi_device_suspend/resume() and ata_dev_ready() removed. * Resume now has to wait for disk to spin up before proceeding. I couldn't find easy way out as libata is in EH waiting for the disk to be ready and sd is waiting for EH to complete to issue START_STOP. * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config(). This fixes spindown on shutdown and suspend-to-disk. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Fix wrong "port" calculations in pdc202xx_{configure_piomode,set_dmamode}() They were broken for all configurations except one (master device on primary channel, no other devices) and as a result device settings + PIO/DMA timings were being programmed into the wrong PCI registers. This could result in a large variety of problems including data corruption, hangs etc. (depending on devices used and your luck :-). ap->port_no ap->devno used PCI registers correct PCI registers 0 0 0x60-0x62 0x60-0x62 0 1 0x62-0x64 0x64-0x66 1 0 0x64-0x66 0x68-0x6a 1 1 0x66-0x68 0x6c-0x6e Also forward port recent fixes from drivers/ide pdc202xx_old driver: * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) and finally bump driver version.

This patch is against each libata driver. Two IRQ calls are added in ata_port_operations. - irq_on() is used to enable interrupts. - irq_ack() is used to acknowledge a device interrupt. In most drivers, ata_irq_on() and ata_irq_ack() are used for irq_on and irq_ack respectively. In some drivers (ex: ahci, sata_sil24) which cannot use them as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

libata used two separate sets of variables to record request size and current offset for ATA and ATAPI. This is confusing and fragile. This patch replaces qc->nsect/cursect with qc->nbytes/curbytes and kills them. Also, ata_pio_sector() is updated to use bytes for qc->cursg_ofs instead of sectors. The field used to be used in bytes for ATAPI and in sectors for ATA. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>
