* Move dynamic sysctl(8) variable creation for the cd(4) and da(4) driversken2003-09-032-43/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | using 512 byte blocks). cam_ccb.h: Bump up volume_size and cylinders in ccb_calc_geometry to 64 bits and 32 bits respectively, so we can hold larger device sizes. cylinders would overflow at about 500GB. Bump CAM_VERSION for this change. Note that this will require a recompile of all applications that talk to the pass(4) driver. scsi_all.c: Add descriptions for READ/WRITE(16), update READ/WRITE(12) descriptions, add descriptions for SERVICE ACTION IN/OUT. Add a new function, scsi_read_capacity_16(), that issues the read capacity service action. (Necessary for arrays larger than 2^32 sectors.) Update scsi_read_write() to use a 64 bit LBA and issue READ(16) or WRITE(16) if necessary. NOTE the API change. This should be largely transparnet to most userland applications at compile time, but will break binary compatibility. The CAM_VERSION bump, above, also serves the purpose of forcing a recompile for any applications that talk to CAM. scsi_all.h: Add 16 byte READ/WRITE structures, structures for 16 byte READ CAPACITY/SERVICE ACTION IN. Add scsi_u64to8b() and scsi_8btou64. scsi_da.c: The da(4) driver probe now has two stages for devices larger than 2TB. If a standard READ CAPACITY(10) returns 0xffffffff, we issue the 16 byte version of read capacity to determine the true array capacity. We also do the same thing in daopen() -- use the 16 byte read capacity if the device is large enough. The sysctl/loader code has also been updated to accept 16 bytes as a minimum command size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel: Change statistics to use the *uptime() timescale (ie: relative to boottime) rather than the UTC aligned timescale. This makes the device statistics code oblivious to clock steps. Change timestamps to bintime format, they are cheaper. Remove the "busy_count", and replace it with two counter fields: "start_count" and "end_count", which are updated in the down and up paths respectively. This removes the locking constraint on devstat. Add a timestamp argument to devstat_start_transaction(), this will normally be a timestamp set by the *_bio() function in bp->bio_t0. Use this field to calculate duration of I/O operations. Add two timestamp arguments to devstat_end_transaction(), one is the current time, a NULL pointer means "take timestamp yourself", the other is the timestamp of when this transaction started (see above). Change calculation of busy_time to operate on "the salami principle": Only when we are idle, which we can determine by the start+end counts being identical, do we update the "busy_from" field in the down path. In the up path we accumulate the timeslice in busy_time and update busy_from. Change the byte_* and num_* fields into two arrays: bytes[] and operations[]. Userland: Change the misleading "busy_time" name to be called "snap_time" and make the time long double since that is what most users need anyway, fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same timescale as the kernel fields. Change devstat_compute_etime() to operate on struct bintime. Remove the version 2 legacy interface: the change to bintime makes compatibility far too expensive. Fix a bug in systat's "vm" page where boot relative busy times would be bogus. Bump __FreeBSD_version to 500107 Review & Collaboration by: ken
