Rename (with #defines) the variables use for aligning partitions to
separate them from the bios geometry.
All in advance of allowing other partition alignments (eg 2048 sectors).
support for short reads.
Ironically, in some cases this works *worse* than the previous
incorrect implementation which silently ignored short reads.
Namely, I can now probe my sd@umass USB stick only once without
having to replug it. Some ugen "bus reset" is probably needed,
but what exactly is unknown, and manual handjobs will have to
suffice for now.
an absolute time instead of a delta. Fix bug which caused timed
tsleeps to always wake up immediately (unless the system clock was
around "0", which was not very probable ;).
read/write/accept, then the expectation is that the blocked thread will
exit and the close complete.
Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.
Also rename fo_abort() to fo_restart() (this used to be fo_drain()).
Fixes PR/26567
- mach_init: use mips_init_lwp0_uarea(), do not hardcode it. Do not call
ksyms_init(), it's called in MI. Also, avoid struct user in few places.
- findroot: use deviter interface.
- give nmi_sun* ENTRY() points so they show up in symbols properly
- add some disabled code to use this cpu's idlelwp area when hatching
a cpu, but right now it makes this worse not better...
- if a cpu doesn't have any mappings allocated, don't copy them. this
occurs if a cpu isn't attached (such as a MP kernel with only "cpu0"
listed in the config file..)
to EAFNOSUPPORT on NetBSD(!). Additionally, at least slowaris and
linux talk only about PF_LOCAL. Finally, since I'm reading a NetBSD
man page, I foremost care about the code working on NetBSD.
Allocate ksiginfo on stack since it is safe and sigget() assumes that it is
not allocated from pool (pending signals via sigput()/sigget() "mill" should
be dynamically allocated, however). Might be useful to revisit later.
Likely the cause of PR/40750 and indirect cause of PR/39283.
in sparc/amd7930intr.s and sparc/bsd_fdintr.s until they are
rewritten to adapt new MI softint(9) API.
No particular comments on PR port-sparc/42192, but
this fixes timeout problem on floppy access on my SPARCstation 1+.
XXX: floppy support on sun4m seems to have another problem (data overrun).
