* [libata] sata_nv: add PCI IDsJeff Garzik2006-06-221-0/+4

* [libata] sata_nv: s/spin_lock_irqsave/spin_lock/ in irq handlerJeff Garzik2006-06-201-6/+4
| | | | | | | | | We don't need to use the heavier spin lock in the irq handler. It's quite possible we can do this in nv_generic_interrupt() as well, but I didn't take the time to pursue that train of thought. Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [PATCH] sata_nv: better irq handlersTejun Heo2006-06-201-17/+194
| | | | | | | | | | | | | nf2/3 and ck804 have irq status register. Implement better irq handler for those flavors of nv. This patch makes different flavors of nv controllers use different irq handlers by using separate port_info for each flavor. This change also makes following EH and hotplug updates easier to integrate. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [PATCH] PATCH: libata. Add ->data_xfer methodAlan Cox2006-05-241-0/+1
| | | | | | | | | | | We need to pass the device in order to do per device checks such as 32bit I/O enables. With the changes to include dev->ap we now don't have to add parameters however just clean them up. Also add data_xfer methods to the existing drivers except ata_piix (which is in the other block of patches). If you reject the piix one just add a data_xfer to it...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

| * [PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 driveAndrew Chew2006-01-091-6/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works around a problem with spurious interrupts seen at boot time when a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

| * libata: bitmask based pci init functions for one or two portsAlan Cox2005-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This redoes the n_ports logic I proposed before as a bitmask. ata_pci_init_native_mode is now used with a mask allowing for mixed mode stuff later on. ata_pci_init_legacy_port is called with port number and does one port now not two. Instead it is called twice by the ata init logic which cleans both of them up. There are stil limits in the original code left over - IRQ/port mapping for legacy mode should be arch specific values - You can have one legacy mode IDE adapter per PCI root bridge on some systems - Doesn't handle mixed mode devices yet (but is now a lot closer to it)

| * [PATCH] fix atapi_packet_task vs. intr race (take 2)Tejun Heo2005-08-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupts from devices sharing the same IRQ could cause ata_host_intr to finish commands being processed by atapi_packet_task if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA protocol. This is because libata interrupt handler is unaware that interrupts are not expected during that period. This patch adds ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not expecting interrupts. Note that once proper HSM is implemented for interrupt-driven PIO, this should be merged into it and this flag will be removed. ahci.c is a different kind of beast, so it's left alone. * The following drivers use ata_qc_issue_prot and ata_interrupt, so changes in libata core will do. ata_piix sata_sil sata_svw sata_via sata_sis sata_uli * The following drivers use ata_qc_issue_prot and custom intr handler. They need this change to work correctly. sata_nv sata_vsc * The following drivers use custom issue function and intr handler. Currently all custom issue functions don't support ATAPI, so this change is irrelevant, updated for consistency and to avoid later mistakes. sata_promise sata_qstor sata_sx4 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* libata: Fix use-after-iounmapJeff Garzik2005-05-261-0/+2
| | | | | | | | | | | | | | | | | | Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch.
