* Tidy up the locking of the bounce pages structures.Maxime Henrion2003-03-171-13/+21
| | | | | | | | | | | | | | | - Use SYSINIT to initialize the structures instead of checking total_bpages against 0 in alloc_bounce_pages(), which could lead to several initializations being done at the same time. - Add missing locking in bus_dmamap_load(), the bounce pages mutex must be held when calling reserve_bounce_pages() and when touching the bounce_map_waitinglist list. - Remove the useless splhigh() and splx() calls. - Assert that the bounce pages mutex is held in reserve_bounce_pages() to catch regressions.

* Remove bogus KASSERT. The 802.11 layer and the resume from suspendWarner Losh2003-03-171-2/+0
| | | | | | | | | | | | | | code both seem to call wi_start (directly or via the if_start pointer) without checking to see if OACTIVE is 0. In addition, I think that with the use of 3 transmit buffers this routine can be called with OACTIVE set, but I might be mistaken about that (and it doesn't matter).

* (This commit certainly increases the need for a wash&clean of vfs_cache.c,Poul-Henning Kamp2003-03-172-412/+377
| | | | | | | | | | | | | | | | | | | | but I decided that it was important for this patch to not bit-rot, and since it is mainly moving code around, the total amount of entropy is epsilon /phk) This is a patch to move the common parts of linux_getcwd() back into kern/vfs_cache.c so that the standard FreeBSD libc getcwd() can use it's extended functionality. The linux syscall linux_getcwd() in compat/linux/linux_getcwd.c has been rewritten to use it too. It should be possible to simplify libc's getcwd() after this. No doubt this code needs some cleaning up, since I've left in the sysctl variables I used for debugging.

* Made the prototypes for pmap_kenter and pmap_kremove MD. These functionsJake Burkholder2003-03-167-2/+12
| | | | | | | | | | | | are machine dependent because they are not required to update the tlb when mappings are added or removed, and doing so is machine dependent. In addition, an implementation may require that pages mapped with pmap_kenter have a backing vm_page_t, which is not necessarily true of all physical pages, and so may choose to pass the vm_page_t to pmap_kenter instead of the physical address in order to make this requirement clear.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=112288
