libata: always use polling SETXFER

2007-06-04T20:48:34+00:00

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.

[libata] sata_via, pata_via: Add PCI IDs.

2007-05-25T09:02:06+00:00

Supplied by VIA.

Also, convert named constants to hex values in the pata_via
PCI ID table.  (standard libata policy for PCI device IDs, which are
considered simply arbitrary hex numbers, without a need to create a
single-use constant in linux/pci_ids.h)

The sata_sis driver supports SATA and PATA ports. The broken support
of both types in one controller is fixed.

Fix build failure for drivers/ata/pata_scc.c

2007-05-25T08:17:31+00:00

The commit d4b2bab4f26345ea1803feb23ea92fbe3f6b77bc added deadline support
to prereset and reset methods to libbata the pata_scc driver wasn't
converted.  This patch is a naive attempt to bring this driver up to
scratch.

Build failures are:
drivers/ata/pata_scc.c: In function 'scc_pata_prereset':
drivers/ata/pata_scc.c:870: error: too few arguments to function 'ata_std_prereset'
drivers/ata/pata_scc.c: In function 'scc_error_handler':
drivers/ata/pata_scc.c:916: warning: passing argument 2 of 'ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c:916: warning: passing argument 3 of 'ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c: In function 'scc_pata_prereset':
drivers/ata/pata_scc.c:871: warning: control reaches end of non-void function

On a releated note scc_bus_post_reset() is (AFACT) identical to
ata_bus_post_reset(), would a patch to make ata_bus_post_reset() assesable
to drivers be accepted?
