Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[libata] license change, other bits - changes license of all code from OSL+GPL to plain ole GPL - except for NVIDIA, who hasn't yet responded about sata_nv - copyright holders were already contacted privately - adds info in each driver about where hardware/protocol docs may be obtained - where I have made major contributions, updated copyright dates

[libata] allow ATAPI to be enabled with new atapi_enabled module option ATAPI is getting close to being ready. To increase exposure, we enable the code in the upstream kernel, but default it to off (present behavior). Users must pass atapi_enabled=1 as a module option (if module) or on the kernel command line (if built in) to turn on discovery of their ATAPI devices.

[libata] change ata_qc_complete() to take error mask as second arg The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

[PATCH] libata CHS: calculate read/write commands and protocol on the fly (revise #6) - merge ata_prot_to_cmd() and ata_dev_set_protocol() as ata_rwcmd_protocol() - pave road for read/write multiple support - remove usage of pre-cached command and protocol values and call ata_rwcmd_protocol() instead Signed-off-by: Albert Lee <albertcc@tw.ibm.com> ============== Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
