* Set UltraDMA transfer mode. Some (early?) SATA drives, such as the Maxtorkettenis2015-12-292-2/+25
| | | | | | | | | | | 7Y250M0, refuse to do DMA unless the transfer mode has been set. This causes reads (and presumably writes) to time out. Unlike the wdc code, this only sets the UltraDMA transfer mode. If we ever want to support ancient PATA drivers through the atascsi layer, we probably need to set the PIO and/or MWDMA transfer modes as well. ok jmatthew@, dlg@)

| | | | | | | | | ST-506 support. Remove redundant 'precomp' variables/fields and rename remaining few to 'features' to be consistant with the rest of the code. Consensus that no ST-506 disks (requiring ISA cards, <120MB, usually rife with bad sectors that can't be worked around) are still running OpenBSD.
* rename the probe and free members of atascsi_methods to ata_probedlg2015-05-152-7/+7
| | | | | | | | and ata_free. this makes them consistent with the rest of the members, and lets me #define free to weird debug things in the kernel without screwing these files up.
* Use config_suspend() instead of dereferencing ca_activate directly tompi2015-04-041-6/+2
| | | | | | | | | | support drivers that do not need any specific suspend/resume magic and do not have an activate function. config_suspend() will automagically propagate the event to the children of the driver. Needed at least by kauaiata(4/macppc). ok deraadt@, mlarkin@

* remove the second void * argument on tasks.dlg2015-01-271-5/+5
| | | | | | | | | | | | | | | | | | | | | when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

| | | | | | | | | | paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin
