The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value. 2010-09-20T07:31:08Z Andriy Gapon avg@FreeBSD.org 2010-09-20T07:31:08Z urn:sha1:7973433a5afef5a1801cd6f671c685ba1a199547 2010-02-14T19:38:27Z Alexander Motin mav@FreeBSD.org 2010-02-14T19:38:27Z urn:sha1:50ae5fde8d275e57e290c224f774b1be55d24deb Large set of CAM improvements: - Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs. 2010-01-22T11:16:46Z Alexander Motin mav@FreeBSD.org 2010-01-22T11:16:46Z urn:sha1:d871d872fadda3aaa6ec6a6f8c25a0d585d3f35b Lock bus scan. 2009-11-04T16:58:26Z John Baldwin jhb@FreeBSD.org 2009-11-04T16:58:26Z urn:sha1:6fd3786837cbda28ee0c01e589ae48dc44d79f9c When the timeout backoff hits the maximum value, leave it capped at the maximum value rather than setting it to the result of a boolean expression that is always true. 2009-08-18T09:31:00Z Alexander Motin mav@FreeBSD.org 2009-08-18T09:31:00Z urn:sha1:a7f9e24d619c2e1bd41fd36029593334d01e05c4 Fix iSCSI initiator and vpo driver operation, broken by CAM changes.

This allows the lpt_release_ppbus() calls in those two routines to actually release the ppbus and thus fixes the hangs noticed with the lpt(4) driver since the recent ppbus changes. The old lpt(4) driver didn't actually check the HAVEBUS flag in lpt_release_ppbus() which is why these bugs weren't noticed before.
