including soft interrupt, and this is way too low in some use (lots of domains,
or domains with lots of xennet, or even hardware with lots of devices at
different interrupts).
Based on idea from YAMAMOTO Takashi, keep one list of handler per-event and
one per-IPL (so the same handler is now in 2 lists). In the common case were
an event is received at low IPL, we can call the handlers quickly (there
is usually only one handler per event, unless the event is mapped to a
physical interrupt and this interrupt is shared by different devices).
Deffered events and software interrupts are handled by a bitmask (as before)
with one bit per IPL. When one IPL has an event pending all handlers for
this IPL will be called.
With this change, it is now possible to have all the 1024 events active.
While here, handle debug event in a special way: the handler is always called,
regardless of the current IPL. Make the handler print usefull informations
about events and IPL states.
Also remove code not used on Xen in files inherited from the x86 port.
and a number of sectors per track.
According to sys/fs/msdosfs/msdosfs_vfsops.c:msdosfs_mountfs(),
the kernel doesn't accept BPB with spt (sector per track) > 63
or hds (drive heads) > 255, so if values taken from disklabel
don't match these restrictions, use popular BIOS default values
(255/63) instead.
started based on the eeprom values and adapter capabilities.
Avoid the driver to negotiate wide transfers with a wide drive connected
to a non-wide capable controller.
Problem reported and fix tested by Dan LaBell on netbsd-help.
- distinguish paddr_t and bus_addr_t.
for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm. we can always grab
machine address from pte.
that a strictly conforming C program uses that name itself, so it had to
be removed. Also put the long comment above the #if 0, because it describes
the #if, not the isblank() macro. Added two blank lines to make the grouping
clear. Approved by kleink.
conversion to construct a quiet NaN on hppa, mips, sh3, and sh5 as well.
Also, remove the portion constructing a ROP on vax; this is not required
by the standard, and in its consequences it is not an appropriate
substitute for a qNaN.
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
entropy collected. It's undocumented, noone else does it and
it leads to "named" errors during boot for me.
Generally, consumers of "/dev/random" should be prepared to wait.
(The other uses of "rnd_have_entropy" look bogus to me too,
but this needs more consideration.)
(they already had default values; we could kill the [...=N] syntax
completely or at least have config(8) assume that a locator with
a default is optional)
if CM descriptor is NOT found but UNION descriotor is found,
use the data interface in it.
Do not require CM or ACM descriptors as long as
the data interface is found.
Should fix NetBSD PR #29754 by rivo nurges.
