2005-10-25[PATCH] libata kernel-doc fixesRandy Dunlap
Correct some function names in kernel-doc. Add some kernel-doc descriptions. Fix some typos. Remove a few blank lines. Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-22libata: const-ification bombing runJeff Garzik
Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.
2005-10-21Add ide-timing functionality to libata.Alan Cox
This is needed for full AMD and VIA drivers and possibly more. Functions to turn actual clocking and cycle timings into register values. Also to merge shared timings to compute an optimal timing set.

2005-10-21[PATCH] enum safety (sata_qstor)Al Viro
sata_qstor strays into a nasty area - gcc handling of wide enums is full of bugs that got fixed between gcc versions creating portability nightmare. Single-member enums are safe, so are ones that stay within the range of int or unsigned int. Anything beyond that is asking for trouble. Declaration of constants split in two enums, taking the ~0UL one into a separate enum. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-10-17[PATCH] Fix and clean up quirk_intel_ide_combined() configurationJeff Garzik
This change makes quirk_intel_ide_combined() dependent on the precise conditions under which it is needed: * IDE is built in * IDE SATA option is not set * ata_piix or ahci drivers are enabled This fixes an issue where some modular configurations would not cause the quirk to be enabled.

This patch adds support for sil_3131 and sil_3531. Both are identical to 3124 except that they have only one port. Bits 30 and 31 of ata_port_info->host_flags is used to encode available port numbers. Version number is bumped to 0.22. Edward Falk supplied all the necessary information and preliminary patch.

2005-10-09[libata scsi] improve scsi error handling with ata_scsi_set_sense()Douglas Gilbert
- change "xlat" and "fill" actors in libata-scsi so they are responsible for SCSI status and sense data when they return 1. This allows GOOD status or a specialized error to be set. - yield an error for mode sense requests for saved values [sat-r06] - remove static inlines for ata_bad_scsiop() and ata_bad_cdb() which are no longer used Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

1) note urgent bug, that completes command twice 2) only fix up INQUIRY data if the SCSI version is zero (typically indicates ATAPI MMC-ish device) 3) if there is a problem on the ATA bus, don't bother with REQUEST SENSE, just directly handle the error based on Status/Error registers.

2005-10-04libata: bitmask based pci init functions for one or two portsAlan Cox
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)
