2006-05-22In wdcprobe(), directly invoke wdc_do_reset() instead of using the resetMiod Vallat
reset function pointer, as this can cause a NULL pointer dereference on some systems.
2006-05-08Revert last commit till a better method can be found.Jonathan Gray
At least one system (Ben Lovett's) had issues with the change.

SATA drive. ok grange@
2006-05-03Provide a function pointer that allows for the wdc resetJonathan Gray
method to be changed as required. This will be required for dealing with several chips in pciide.

2004-10-17Add a callback drv_probe() to allow underlying ata controller driverAlexander Yurchenko
to probe for drives in its own way. It's a no-op for now but will be needed for native sata support.

2004-02-19wdc logs fixes from costa@:Alexander Yurchenko
1) wdc_get_log is at splbio() to prevent interrupt handlers from updating the log 2) work hard to ensure that wdc_tail and wdc_head are between 0 and wdc_log_cap, even if wdc_log or wdc_get_log is run concurrently against itself. With this patch, running concurrent wdc_log's may corrupt the log, but it should not cause any panics. 3) Make sure the buffer always starts on a record boundary. Otherwise said, wdc_tail should always be on a record boundary.
2004-01-23Use %b to display status register, this will make bug reports moreAlexander Yurchenko
informative. Also convert WDCS_BITS string to caps.

2003-11-17Don't wait for DRQ after issuing IDENTIFY command; instead check for DRQAlexander Yurchenko
asserted after BSY is cleared in data read codepath. Solves delays in probe. The first version of this diff was done by costa@ a long time ago but had some issues. This one is a partial sync with NetBSD. ok costa@

2003-10-27Skip ATA modes detection for SATA drives, it's useless and someAlexander Yurchenko
SATA drives really don't like it. Add a delay between drive reset and issuing IDENTIFY command, some drives need it (from NetBSD). This fixes problems with SATA drives reported by Jonathon Fletcher <jonathon.fletcher@pobox.com>. He also provided access to the test machine.
2003-10-26Print error registers values in debug message after reset too.Alexander Yurchenko
2003-10-26Device reset improvements:Alexander Yurchenko
- put the reset protocol itself in the separate function __wdcdo_reset() so we don't need anymore to keep in sync two reset code paths; - change the reset protocol to something like FreeBSD and NetBSD do, this fixes slave ATA drive detect with weird ATAPI master (reported by fgsch@); Discussed with costa@. Tested by me, fgsch@, millert@, canacar@.

Tom: I did not commit a couple of your changes. i did not include some punctuation fixes (full stops, etc.) mnemorable -> mnemonic: i decided memorable was probably better instrunctions -> instruction: i kept the plural

2003-10-17Merge an old fix from NetBSD:Alexander Yurchenko
- do not stop/unload current DMA operation if an IRQ was not detected by DMA engine unless the force flag was given, fixes DMA problems in shared IRQ setups; - ack interrupt before entering DMA codepath Tested by many. Work by niklas@ but he doesn't want to commit it for some reason.

2002-01-23Pool deals fairly well with physical memory shortage, but it doesn't dealArtur Grabowski
well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
