rin | ld(4): Convert blkno argument for sc_dump() to daddr_t
PR kern/59153
(1) For backends that accept 64-bit block address, i.e.,
nvme(4), virtio(4), aac(4), iop(4), and mainbus(usermode/4),
this should enable to dump beyond 2Gi blocks.
(2) sdmmc(4) backend allows to dump up to the last block.
(3) For other backends, block address is handled as `int`.
Some of them may support blocks up to 4Gi, but I do not have
enough time to examine datasheets. So, continue to reject >2Gi
blocks as before.
XXX
This is KABI change, and cannot be pulled up into netbsd-{10,9}.
XXX
Compile-test only (for amd64/ALL) due to lack of large SSDs ;)
Thanks mlelstv@ for discussion and careful review!!

ld(4): Block requests while suspended until resumed.
Otherwise nothing stops us from continuing to feed I/O to the disk
controller when it expects that the queues are quiesced as it pokes
registers to change its power states. Fixes resume during disk

Remove unnecessary wait in ldbegindetach.
Like disk_begindetach, ldbegindetach only commits to detaching but
doesn't wait for existing xfers to drain; it is up to the driver to
abort them, once we are committed, and then ldenddetach to wait for
them to drain.

Add a flag to dk_dump for virtual disk devices.
If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.
If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.
With this, I can now dump to dk on cgd on dk on wd.

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.

Don't use BUFQ_FCFS. It degrades performance both for "smart" (Mylex
ExtremeRAID with NV cache) and "dumb" (3ware 6410) ld providers.
Instead, use the default buffer queue policy.
With the 3ware adapter, using the read priority strategy instead of FCFS,
for three extractions of pkgsrc, took 329 seconds instead of 331 -- but
with a dramatic improvement in perceived system response (latency for
I/O outside the main stream).
With the Mylex adapter, the improvement was dramatic: using read priority
instead of FCFS yielded an improvement from 381 seconds to 135 seconds!
There was a less-noticeable improvement in perceived latency as well.
The other disk drivers currently hard-wired to FCFS or another policy
should probably be changed as well.

by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Since the minor numbers belonging to the partitions of a disk are not
contigous anymore, we can't call vdevgone() for the whole range at once.
(we should probably change the vdevgone() interface)
This also fixes some wrong use of DISKUNIT().

device.
* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass
to VOP_REVOKE
* the revoke system call will revoke all aliases, as before, but not the
clones
* vdevgone is called when detaching a device, so make it use REVOKECLONE
to get rid of all clones as well
* clean up all uses of VOP_OPEN wrt. locking.
* add a few VOPS to spec_vnops that need to do something when it's a
clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
to the specinfo of a cloned vnode. could possibly redirect getattr to
the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
original device, and reassociates it with the specified dev_t. to be
used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
when debugging race conditions that still exist wrt. locking and
revoking vnodes.
* make the locking state of a vnode consistent when passed to
d_open and d_close (unlocked). locked would be better, but has
some deadlock issues

6) Remove individual open-coded delta-estimators for values from a few

clamp total number of sectors to UINT32_MAX instead of providing the
lower 32bit of the 64bit number.
No longer warn about differences bewteen disk size and total sector count
in disklabel when the latter is just clamped to the maximum.

|
| 1.94.2.2 |
| 19-Jul-2016 |
pgoyette | Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.
As suggested by riastradh@

pgoyette | Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
are built as modules.

now abandoned doe to cvs merge botch).
The branch now builds, and installs via anita. There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

While ld(4) is MP safe, many backends are not.
Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling
into a backend that doesn't have the flag set. Do the same for the
discard routine.
Fixes PR 52462.
Defer sdmmc discard operations to the sdmmc task queue. Fixes a panic
introduced by ld.c r1.102.
validate length for discard operation and split operation when byte length
doesn't fit into 'int'.
make the sc_discard interface for the ld backend asynchronous and
signal completion through new callback lddiscardend. Use a standard
struct buf to pass disk address and range instead of two off_t values.
make lddiscard synchronous again. This is a requirement of the current
ffs discard code.
Initialize error also in the case where len=0, which just succeeds.
while here, assert that the len is indeed non-negative. this is already
confirmed by sys_fdiscard, but let's be sure.

ld(4): Block requests while suspended until resumed.
Otherwise nothing stops us from continuing to feed I/O to the disk
controller when it expects that the queues are quiesced as it pokes
registers to change its power states. Fixes resume during disk
activity on my T480 with nvme.

Add a flag to dk_dump for virtual disk devices.
If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.
If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.
With this, I can now dump to dk on cgd on dk on wd.
