- d_diskstart callback now processes a single buffer only.
The new wrapper function dk_start processes the queue,
performs other buffer handling and also provides locking
for the the data structures.
- add d_discard callback to handle device specific function inside
the new dk_discard helper function.
Replace splbio with mutex to protect queue and disk structure.
Refactor common code in dk_strategy and dk_discard into dk_translate.
Adjust and simplify ld(4), cgd(4) and xbd(4) drivers accordingly.
ld(4) now becomes MP_SAFE.
Bump kernel version.
Merge common disk driver functionality in ld.c with dksubr.c.
Adjust the two previous users of dk_intf (cgd and xbd) to
the changes.
bump kernel version to 7.99.14
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
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.
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.
"poll" flag when called from ld_shutdown().
This is the infrastructure part of kern/38655 - in itself it doesn't
fix the panic referenced in that PR.
XXX: At least ld_twa.c and perhaps ld_iop.c and ld_icp.c need to
check for this new poll flag and do something useful.
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.
disk framework. This stops ld(4) from returning an error for various
ioctl() requests which actually *did* work. As a result fdisk(8) and
therefore also sysinst(8) work with ld(4) devices once again.
Based on a patch supplied by Todd Kover in PR kern/36244, successfully
tested with ld(4)@icp(4).
