* wdc logs fixes from costa@:grange2004-02-191-57/+81
| | | | | | | | | | | 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.

* Skip ATA modes detection for SATA drives, it's useless and somegrange2003-10-271-3/+19
| | | | | | | | | | 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.

* Device reset improvements:grange2003-10-261-9/+15
| | | | | | | | | | | - 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@.

* Merge an old fix from NetBSD:grange2003-10-171-1/+41
| | | | | | | | | | - 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.

* Pool deals fairly well with physical memory shortage, but it doesn't dealart2002-01-231-2/+2
| | | | | | | | | | | | | | | | | | 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.

Move fix for a flash device that doesn't wake up until a command is sent Try to supress spurious interrupts. However, if one does happen, acknowledge it anyway by reading status. This prevents the interrupt condition from persisting.
