* Change the disk(9) API in order to make device removal more robust.Poul-Henning Kamp2004-02-182-44/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly. Notes: svn path=/head/; revision=125975

This should also eliminate the need for the initial TUR in cdsize(). cam_periph.c: Don't keep retrying if the error we get back is a fatal error. This should help us detect the transition from "Logical unit not ready, cause not reportable" to "Medium not present" in the "TUR many" handler. (The TUR many handler gets triggered for Logical unit not ready, cause not reportable errors.) scsi_cd.c: Remove the initial test unit ready in cdsize().

* Move dynamic sysctl(8) variable creation for the cd(4) and da(4) driversKenneth D. Merry2003-09-032-43/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | out of cdregister() and daregister(), which are run from interrupt context. The sysctl code does blocking mallocs (M_WAITOK), which causes problems if malloc(9) actually needs to sleep. The eventual fix for this issue will involve moving the CAM probe process inside a kernel thread. For now, though, I have fixed the issue by moving dynamic sysctl variable creation for these two drivers to a task queue running in a kernel thread. The existing task queues (taskqueue_swi and taskqueue_swi_giant) run in software interrupt handlers, which wouldn't fix the problem at hand. So I have created a new task queue, taskqueue_thread, that runs inside a kernel thread. (It also runs outside of Giant -- clients must explicitly acquire and release Giant in their taskqueue functions.) scsi_cd.c: Remove sysctl variable creation code from cdregister(), and move it to a new function, cdsysctlinit(). Queue cdsysctlinit() to the taskqueue_thread taskqueue once we have fully registered the cd(4) driver instance. scsi_da.c: Remove sysctl variable creation code from daregister(), and move it to move it to a new function, dasysctlinit(). Queue dasysctlinit() to the taskqueue_thread taskqueue once we have fully registered the da(4) instance. taskqueue.h: Declare the new taskqueue_thread taskqueue, update some comments. subr_taskqueue.c: Create the new kernel thread taskqueue. This taskqueue runs outside of Giant, so any functions queued to it would need to explicitly acquire/release Giant if they need it. cd.4: Update the cd(4) man page to talk about the minimum command size sysctl/loader tunable. Also note that the changer variables are available as loader tunables as well. da.4: Update the da(4) man page to cover the retry_count, default_timeout and minimum_cmd_size sysctl variables/loader tunables. Remove references to /dev/r???, they aren't used any longer. cd.9: Update the cd(9) man page to describe the CD_Q_10_BYTE_ONLY quirk. taskqueue.9: Update the taskqueue(9) man page to describe the new thread task queue, and the taskqueue_swi_giant queue.
