Generalize it to also tidy up allocation of receive DMA maps. And change a
few of the symbol names involved to (1) make sure all uses have been fixed
and (2) make it clearer what's actually going on.
Previously the driver was using DMA maps off the free list without fully
allocating them, apparently in order to save two or three lines releasing
them on error paths. According to the submitter of the PR (H.Saito) this
was causing it to reuse a map already in use when under load, resulting
in panics.
I'm not sure if that ought to have been possible or if it reflected an
interrupt handling bug somewhere else, but the change is an improvement
regardless, so we'll go with it.
Compile-tested only, but I've crosschecked the diffs and all that and it's
a pretty noninvasive change.
(Is anyone actually using this driver rather than tlp?)
signals (i.e. SA_KILL), just if SIGKILL (or SIGCONT). Improve comments.
Make some functions static, remove unused sigrealloc() prototype.
Fixes PR/39814. Similar patch reviewed by <ad>.
address space available to processes. this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- patch sh, and csh to notice RLIMIT_AS. (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information. (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897. it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)
are dealt with in x86/tsc.c and callers don't have to care that much.
Also add some comments and make some variables static.
approved by ad (a while ago)
There are also sigtimedwait(2) et al. to catch signals without invoking
a signal handler. Fixes PR kern/41076 by Matteo Beccati (the first
test case, where the signal is sent before sigwaitinfo(2) gets called).
the quirk table. This way they attach as ahcisata and work, instead of
attaching as viaide and failing miserably.
Fixes PR kern/37826.
