thorpej | branches: 1.53.8;
Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

|

| 27-Oct-2012 |
chs | branches: 1.47.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

| 1.46 |
| 02-Feb-2012 |
tls | branches: 1.46.6;
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.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
|
| 1.36 |

|

| 15-Oct-2005 |
yamt | - change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)

drochner | kill some more simple submatch() functions, use config_stdsubmatch()
|
| 1.29 |
| 25-Aug-2005 |
drochner | replace the "locdesc_t" structure carrying the number of locators
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks
|

|

just for sanity
|
| 1.24 |
| 30-Aug-2004 |
drochner | There is no point in using config_found_sm() if there is no submatch function.
(actually, there should be one...)

originating from Jonathon Gray and forwarded by jmc@openbsd.
|

christos | Fix uninitialized variable warnings
|
| 1.21 |
| 01-Nov-2002 |
mrg | branches: 1.21.6;
implement separate read/write disk statistics:
- disk_unbusy() gets a new parameter to tell the IO direction.
- struct disk_sysctl gets 4 new members for read/write bytes/transfers.
when processing hw.diskstats, add the read&write bytes/transfers for
the old combined stats to attempt to keep backwards compatibility.
unfortunately, due to multiple bugs, this will cause new kernels and old
vmstat/iostat/systat programs to fail. however, the next time this is
change it will not fail again.
this is just the kernel portion.

jdolecek | branches: 1.16.2;
edc_cmd_wait(): it is absolutely necessary to wait for the BSR_CMD_INPROGRESS
flag to clear, even when the COMMAND COMPLETE interrupt already did happen,
otherwise we get ATTENTION ERROR for next command if it happens soon
enough; this fixes the reliability problems introduced by previous change
some other cleanup & simlify of edc_cmd_wait()/edc_run_cmd(), the 'secs'
is just a hint used in !poll case only
add some comments
move status_block[] back to edc_mca_softc, to save stack memory
make #ifdef DEBUG #ifdef EDC_DEBUG and g/c some obsolete debug stuff
make some EAGAINs EIOs
edc_intr(): wakeup the waiter for any command, not just READ/WRITE DATA
|

| 31-Dec-2001 |
thorpej | Labels must be followed by statements.
|

jdolecek | it doesn't make sense to wait for resources during autoconfiguration
|
| 1.13 |
| 04-Dec-2001 |
sommerfeld | Fix so these files build with options DEBUG enabled.
The change to edc_mca.c may not work as I don't have any mca hardware.
|
| 1.12 |
| 02-Dec-2001 |
jdolecek | use the new MCABUS_DMA_16BIT flag to use 16bit DMA (not implicit anymore)
|
| 1.11 |
| 23-Nov-2001 |
jdolecek | Convert over to use the new MCA DMA facilities, which encapsulate
the MCA DMA controller access. This also means we gain >16MB RAM support.
While here, overhaul the driver to saner state, especially:
* simplify and clean the attach code a lot, and support the 'drive'
locator
* pass proper dev_t to readdisklabel() - formerly, the passed value was
completely broken (used incorrect major and wrong minor), but worked
by accident
* worker thread is now spawned per controller, rather than per-drive;
i/o cannot be done concurrently by different drivers, only one
i/o can be pending at any time
* simplify the command queue code, just sleep appropriately when
!poll case, g/c 'async' code formerly needed, move the bio code
from ed_mca.c to edc_mca.c:edc_bio()
* put all string arrays used by edc_dump_status_block() within #ifdef EDC_DEBUG,
and use numbers instead if it's not defined; this cuts object size by 5KB
* other misc cleanups
|

lukem | add RCSID
|
| 1.9 |
| 04-May-2001 |
jdolecek | branches: 1.9.2; 1.9.4;
Implement polled command mode, and use it for writing system dump
and for initial autoconf probes; the latter eliminates need for
deferred configuration (and makes dmesg a bit nicer).
g/c EDF_IODONE flag - protect against interrupt by calling tsleep()
at splbio in worker thread
g/c unneeded stuff, improve some autoconf messages
|
| 1.8 |

|
| 1.6 |
| 23-Apr-2001 |
jdolecek | branches: 1.6.2;
Compact autoconf info by printing the IRQ number together
with 'at mca0 slot foo' info.
|
| 1.5 |
| 22-Apr-2001 |
jdolecek | g/c edc_dev_status[]
|
| 1.4 |
| 22-Apr-2001 |
jdolecek | fix edc_dump_status_block() to correctly print Command Error Code and
Device Error Code/Status when appropriate
add one item to TODO - need support for kernel memory crash dumps (to be
implemented "soon")
|
| 1.3 |
| 22-Apr-2001 |
jdolecek | edc_dump_status_block(): print RBA # and block count as unsigned
|
| 1.2 |
| 22-Apr-2001 |
jdolecek | Fix serious bug in bounce buf handling - the EDF_BOUNCEBUF flag needs
to be cleared always in edmcadone(), otherwise if there is a write
via bounce buffer followed by read directly to buf, the read operation
would return trashed data (the buf data would get overwritten
by contents of bounce buffer in edmcadone()).
Reset b_resid as necessary when the i/o is done, too.
g/c some unneeded stuff, use lockmgr()-style locking in ed_[un]lock(),
better avoid some deadlocks
These changes make the driver quite a bit more stable. It's actually
reliable enough to be possible to newfs the drive and use it for
read/write filesystem now.
|
| 1.1 |
| 19-Apr-2001 |
jdolecek | Use "edc" instead of "dasd". As pointed out by Soren, dasd doesn't
mean anything special in IBM-talk. And edc better matches prior art, too.
