designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
requiring a message, we will most likely get that from the spinup attempt
anyway.
This avoids the spurious "Check Condition on CDB, Not Ready, Medium Not
Present, Tray Closed" messages at boot/shutdown time.
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.
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.
good idea), at least set up all values to the fake values, as the caller
expects.
Should fix PR kern/39904, though if noone can find out why the fake value
would be needed, we should change it to just return 0 as suggested in the PR.
(and silently) check for presence of media. While this would be easy
to implement via SCIOCCOMMAND, our kernel has quirks for this
command, which otherwise would not be readily available to userland
applications.
- 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>).

partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.
No objections on tech-userlevel@.
device will remain in a wait-for-more-stuff-to-be-written state delaying other
SCSI calls, esp. some read-size or read-layout calls, until its told there is
no more comming.
To fix this, on last close explicitly flush the caches releasing the device
from this mode and allowing other SCSI commands to reach it.
This fixes PR 40528
partitions on optical media like CD/DVD/BD but also on all other media if
there is no NetBSD disklabel or MBR label.
Also fix cd's readdisklabel arguments so the ioctl's arrive at the right
device (!) and update its default label to make more sense.
up of write parameters call and a call to perform a series of operations on
these devices.
Note that the MMC framework interface is still not exposed to userland
unless the expose_mmc flag is set. This is to prevent applications to build
on a possibly still moving target. This flag will eventually be removed.
They state f.e. that a recordable CD-R is rewritable or completely forget
that the fixed packet size formatted CD-RW is strict overwrite rewritable
and not randomly rewritable.
(Sense code 0x04, 0x07) not a fatal error anymore but retry command later.
This sense code can be returned on a CD-MRW write that encounters a bad
block resulting in the drive being busy relocating it. During that time it
can return this sense code to indicate its busy for a while.
Also reduce waiting time for the other "Logical Unix Not Ready, Long Write
In Progress" to half a second.
conceptional bug in mmc_discinfo, improves DVD+R feature detection and
prevents corruption of mmc_trackinfo readout on some devices that return
short trackinfo structures.
