Expand struct scsipi_bustype {} in a ABI-backward-compatible way to
pass more informations about the bus:
- bustype_type has 2 different bytes, one holding the existing
SCSIPI_BUSTYPE_* (scsi, atapi, ata), and one for a per-SCSIPI_BUSTYPE_*
subtype. Introduce macros to build or extract bustype_type.
- for SCSIPI_BUSTYPE_SCSI, define subtypes for parallel SCSI, Fibre Channel,
SAS and USB, to specify the transport method. SCSIPI_BUSTYPE_SCSI_PSCSI
is 0 so that bustype_type value doesn't change for existing code
- for non-SCSIPI_BUSTYPE_SCSI busses there's no defined subtype yet,
so the bustype_type value doesn't change.
- provide scsi_fc_bustype, scsi_sas_bustype and scsi_usb_bustype
along with scsi_bustype to be used by bus driver where appropriate
- scsipi_print_xfer_mode(): more existing code under a
(SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_PSCSI) case, as
sync/wide parameters only make sense for parallel SCSI.
For (SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_FC) and
(SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_SAS), only print
tagged queing status if enabled. Just be silent for other
bustypes.
This change is prompted by this problem:
right now, FC (e.g. isp(4)) and SAS (e.g. mfi(4)) don't
do anything for ADAPTER_REQ_SET_XFER_MODE, and especially never
call scsipi_async_event(ASYNC_EVENT_XFER_MODE), so sd(4) always
runs untagged. Doing a scsipi_async_event(ASYNC_EVENT_XFER_MODE) with
appropriate parameters is enough to enable tagged queuing,
but then scsipi will print:
sd0: async, 8-bit transfers, tagged queueing
which is harmless (async, 8-bit transfers doens't make sense on SAS anyway)
but will confuse users. With this change scsipi will only print:
sd0: tagged queueing
which is correct.
In the long run, knowning the underlying transport in scsipi will
allow better handling of device which are not parallel SCSI.
Another change adding an extra callback to struct scsipi_bustype {}
will come (so that scsipi_print_xfer_mode(), which is SCSI-specific,
can be moved out of scsipi_base, and split into per-subtype callback),
but this will break kernel ABI and so is not suitable for
netbsd-6, so will be commmited later. The above is enough to get
tagged queuing on FC and SAS in netbsd-6.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.
ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

rmind | Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).
Discussed on <tech-kern>, reviewed by <ad>.

pgoyette | 1. Move the mode_select functionality into common code (in st.c) and
invoke the common routine for both scsi and atapi tapes.
2. Replace a numeric constant with some sizeof's when calculating the
size of the mode_select command buffer, clear the entire buffer, and
KASSERT to ensure the page_0_size loaded from quirk table is valid.
3. Add a quirk for my Seagate Travan-40 tape drive.

thorpej | Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.

bouyer | Make the xxstart() functions reentrant again, as some drivers HBA can call
scsipi_done() from their scsipi_request().
For this, add a struct scsipi_xfer * argument to scsipi_command().
If not NULL scsipi_command() will use this to enqueue this xfer, otherwise
it'll try to allocate a new one. This scsipi_xfer has to be allocated
and initialised by scsipi_make_xs() or equivalent.
In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL,
dequeue the buffer before calling scsipi_command(). This makes sure that
scsipi_command() will not fail, and also makes sure that xxstart() won't
be called again between the BUFQ_PEEK() and BUFQ_GET().
Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in
private mail and Andreas Wrede on current-users@.
Thanks to Jason Thorpe and Chuck Silver for review, and Andreas Wrede for
testing the patch.

he | Pull up revision 1.12 (via patch, requested by bouyer in ticket #837):
Improve handling of memory shortage, to fix problems like:
sd3(mpt0:0:1:0): unable to allocate scsipi_xfer
sd3: not queued, error 12
The theory is that other consumers of pool memory is causing
this memory shortage in certain somewhat hard to reproduce
situations.
This is done by giving scsipi_command an extra argument to
optionally pass a preallocated scsipi_xfer, and allocating a
scsipi_xfer before dequeueing a buffer in the various *start()
functions. If the allocation of a scsipi_xfer fails, schedule
a callout for delayed invocation of the start function. Also
reserve one page for scsipi_xfer structs, to ensure that we will
eventually have some available once pending commands complete.
Should fix PR#25670.
